ITEM 1 SUMMARY
The Wabamisk project, situated approximately 290 kilometres north of the town of Matagami in the province of Québec, occurs in the James Bay territory a few kilometres south of the Eastmain River near the evacuator on the Opinaca Reservoir (Figure 1). In geological terms, the Wabamisk property occurs in the La Grande Subprovince in the central part of the Superior Province, and more specifically in the Lower Eastmain greenstone belt.
From 2005 to 2009, several gold showings were discovered on the Wabamisk property by Virginia Mines. The Isabelle showing, discovered in 2007, is one of the most significant mineralized zones found to-date with values of 6.48 g/t Au over 3.0 m, 4.20 g/t Au over 13.61 m and 316 g/t Au over 1.00 meter from surface channelling. The best drilling results also came from the Isabelle showing with values of 46.5 g/t Au over 4.0 metres from 2010 drilling campaign. Detailed mapping revealed the shear-hosted nature and early timing of the gold mineralization and identified at least 3 phases of deformation. More recently, field exploration carried out by Virginia in 2010 uncovered several gold showings including 359.6 g/t Au and 15.6 g/t Au in grab samples from the NE part of the property.
Drilling was undertaken during the winter of 2011 but results were not up to expectations. Following this the summer 2011 exploration program focused on other gold occurrences that had been previously discovered in the area. This led to the discovery of a dozen new Au showings associated with quartz veining and arsenopyrite disseminations within locally altered wacke. Except for the Ross showing that returned values up to 70 g/t Au and the Boomerang showing that returned values up to 27.7 g/t Au, the others returned values between 1.0 to 10.0 g/t Au.
In the summer of 2012 prospecting and mechanical stripping exposed a new, significant gold system characterized by a field of quartz veins with visible gold occurring in a sequence of folded metawackes for over 900 m in strike length. The centimetre- to metre-scale quartz veins are locally accompanied by an envelope of intense alteration (silica-sericite-sulphide) up to a few metres thick.
The main gold-bearing structure, the Mustang vein, was exposed by trenching for a distance of over 425 m in a SW-NE direction. As seen at surface, the Mustang vein and its alteration envelope form a slightly sigmoidal structure up to a few metres thick. The vein is oriented WSW-ENE and dips steeply (75°- 80°) to the north. Many gold grains were found in several locations along the entire length of the Mustang vein. Although sulphides are not generally abundant in the vein, the alteration envelope contains up to 5% disseminated arsenopyrite and a few gold grains. Values of 9.66 g/t Au over 4 metres, 3.3 g/t Au over 3.5 metres, 1.99 g/t Au over 1 metre, 18.35 g/t Au over 1 metre, 23.28 uncut (11.14 cut) g/t Au over 4.6 metres, 18.15 g/t Au over 1.7 metres, 8.47 g/t Au over 2.4 metres, 4.46 g/t Au over 2.7 metres, 3.71 g/t Au over 3 metres, 10.15 g/t Au over 0.85 metres, 3.6 g/t Au over 5 metres, 7.65 g/t Au over 1.7 metres and 3.29 g/t Au over 2 metres were returned from channel samples spaced at approximately equal intervals along the length of the Mustang vein.
Other mineralized zones just to the NE of the Mustang vein in the Main Stripped zone also returned significant intersections from channel samples, including 3.45 g/t Au over 6.95 metres, 2.47 g/t Au over 6.8 metres, 3.09 g/t Au over 1.3 metres, 5.47 g/t Au over 4 metres and 4.99 g/t Au over 3 metres. In several cases, these zones appear to be associated with a network of quartz veins and veinlets rather than a single structure as is the case of the Mustang vein.
Mapping and prospecting carried out outside the Main Stripped zone also led to the discovery of other interesting gold showings in several locations on the Wabamisk grid. Most of these showings consist of centimetre- to decimeter-scale quartz veins locally containing visible gold and hosted within variably silicified and chloritized metawackes with traces of sulphides (arsenopyrite and pyrrhotite). Grab samples collected to characterize these new showings returned values varying between 1.6 and 27.6 g/t Au while channel samples yielded results ranging from low values to values of up to 6.73 g/t Au over 2 metres.
In February of 2013 a diamond drill program was undertaken to discover gold-bearing structures at depth. Three main areas were drilled: (1) the Mustang vein, (2) the Sandpit and east Sandpit, and (3) the Power Line east of the Main Stripped zone. In all, 29 boreholes were drilled for a total of 4472 metres. Gold mineralization was cut in
Virginia Mines

almost all boreholes and the Mustang and other gold-bearing veins were successfully intersected at depth. The most significant intersections from the Mustang vein include 3.66 g/t Au over 1.5 m (WB-13-002), 22.65 g/t Au over 2.25 m (WB-13-005) and 3.93 g/t Au over 2.8 m (WB-13-005). Other significant intersections from the Main Stripped zone include 3.99 g/t Au over 1.1 m (WB-13-005), 1.98 g/t Au over 13.4 m, including 4.14 g/t Au over 4.0 m, (WB-13-015), 5.66 g/t Au over 1.0 m (WB-13-018) and 6.06 g/t Au over 3.2 m and 18.05 over 0.8 m (WB-13-025). There were no significant intersections over 0.5 g/t Au from the three boreholes drilled near the power line to the east of the Main Stripped zone.
The summer/fall exploration program on the Wabamisk property extended from the beginning of June to the middle of October. Work on the Wabamisk property was conducted concurrently with work on the adjacent Anatacau property, which is filed in a separate report. The exploration program consisted of prospecting, mechanical stripping, channel sampling, whole-rock analysis and till sampling on both properties. This work was done on two cut-line grids upon which a pole-dipole IP survey was completed during the winter of 2013, at the same time as the winter 2013 drilling campaign. The grids were designed to follow favourable gold-bearing rocks and structures to the NW and SW of the significant gold discoveries (Mustang zone) exposed by trenching in 2012 and drilling in 2013. Targets for trenching were selected on the basis of their geophysical anomalies, host-rocks and structures.
The 2013 campaign was successful in discovering several new gold showings and extensions of gold mineralization discovered by earlier Virginia programs. The most significant new result was the discovery late in the summer of a gold-bearing corridor approximately 8 km to the WNW of the Mustang vein. This corridor, in which the gold showings appear to occur in two clusters at either end, is almost 3 km long along an E-W direction. The gold occurs in quartz veins, quartz veinlets and to some extent the enclosing altered greywacke wall rock. For the most part, the host rocks consist of fresh fine to medium grained greywacke which becomes variably silicified, sericitized and chloritized as the veins are approached. Actinolite and tourmaline are also present. The altered greywacke is also sulfidized, and disseminated pyrite, pyrrhotite and arsenopyrite form up to 7.5% of the rock. Native gold occurs as fine to medium grains in the quartz vein and adjacent wall rock. Locally, several dozen gold grains may be observed in hand sample, and grab samples returned values of up to 278 g/t Au (364347). Channel samples, however, returned more modest values up to 5.67 g/t Au (364510) over 1.0 m.
The 2013 campaign was also successful in increasing the extent of gold showings that had been previously discovered by Virginia Mines, such as the Powerline and adjacent showings discovered in 2009 and 2011. These gold-bearing veins occur in greywacke, gabbro and conglomerate to the east of the new gold corridor, and may in fact represent its continuation to the east. If so, than this corridor would be almost 6 km long and become a significant new target for exploration in the future.

As of December 2013 the Wabamisk property consisted of 1004 map-designated claims for a total of 52732.02 hectares (Figure 2). A block of 99 map-designated claims totalling 5219.33 hectares was dropped from the property in early 2013. The 69-claims block (formerly known as the Lac H property) was acquired from SOQUEM Inc. and Ressources D'Arianne Inc. The obligations that must be met in order to retain the property and the expiration date of the claims are listed in Appendix 1.
These claims are 100% held by Virginia Mines Inc. The former 69 claims from Lac H property are subject to royalty, 38 of which are subject to a 1.5% NSR in favour of Inco Vale (formerly Inco Ltd.). Half of this royalty (0.75% NSR) is redeemable for $750,000. The 31 remaining claims are subject to a total 1.5% NSR to SOQUEM and D’Arianne. Half of this royalty (0.75% NSR) is redeemable at any time for $750,000. All other claims on the property are free of any royalty, back-in rights or other encumbrances and there are no known environmental liabilities.

ITEM 5 ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE AND PHYSIOGRAPHY
The property is located approximately 60 km northwest of the Cree community of Nemaska (Figure 1), and about 20 km east of the James Bay highway linking Matagami to Radisson. Two high-voltage (735 kV) power lines run along the eastern edge of the property and a lower-voltage (69 kV) power line crosses the property south of the Eastmain River.
The northern part of the property is accessible by road while the southern part is accessible by air. The camp may be reached by either the paved James Bay highway to kilometre 395, then along 45 km of all-weather gravel road. Alternatively the camp may be reached via the all-season gravel highway that runs north from Chibougamau to the Nemiscau outpost and north again to the Hydro-Quebec installations along the Eastmain River and beyond to the Opinaca aerodrome (now closed). This road links up with the gravel road running east from the James Bay highway. Since the fall of 2007, an ATV trail leads to the central part of the project (northeast part of Anatacau Lake) and also to the Isabelle showing on the southwest shore of Anatacau Lake. The Opinaca aerodrome lies on the property 2 km southwest of the exploration camp.
Topographic relief on the property is typical for the James Bay area of Québec. It is characterized by gentle relief with rolling hills, abundant lakes, rivers, streams, and swamps and sparse to medium-density conifer forests. Altitudes range between 190 and 310 metres above sea level. The drainage pattern is marked by the presence of numerous lakes on the property, including Anatacau Lake in the central part. Numerous bogs and fens occur in the southern half of the property. Water drains north, towards the Eastmain River.
The ground is snow covered from the end of October to mid-May preventing all fieldwork with the exception of drilling and geophysical survey.
ITEM 6 HISTORY
6.1. Property ownership
The Lac H property was the object of an agreement pursuant to which the Company acquired a 100% interest in the 69 claims constituting the Lac H property, equally owned by SOQUEM Inc. (“SOQUEM”) and D’Arianne, in consideration of the issuance of a total of 50,000 common shares of the Company’s share capital (25,000 to SOQUEM and 25,000 to D’Arianne). Of the 69 claims constituting the property, 38 are subject to a 1.5% NSR in favour of Inco Vale (formerly Inco Ltd.). Half of this royalty (0.75% NSR) is redeemable for $750,000. As for the 31 remaining claims, they are subject to a total 1.5% NSR to SOQUEM and D’Arianne. Half of this royalty (0.75% NSR) is redeemable, at any time, for $750,000. The claims constituting the Lac H property have been merged with the Wabamisk property owned by the Company immediately west.

ITEM 7 GEOLOGICAL SETTING AND MINERALIZATION
7.1. Regional Geology
The Wabamisk project is located in the James Bay region within in the central Superior Province. Four geological subprovinces of Archean age are present from north to south: the La Grande, Opinaca, Nemiscau, and Opatica subprovinces. These subprovinces are essentially composed of metamorphosed volcanic, plutonic, and sedimentary rocks that were subsequently intruded by post- or late-tectonic granitic intrusions. The Wabamisk property is underlain by rocks of the La Grande subprovince (Figure 3).
The La Grande subprovince is primarily composed of volcanic and plutonic rocks (Card and Ciesieski, 1986). It wraps around the Opinaca subprovince to the west, forming a large crescent. The geological contacts with the Nemiscau and Opinaca subprovinces are transitional, grading from dominantly volcano-sedimentary rocks to paragneiss. No ductile faults are reported along the contact zone. The La Grande subprovince comprises about 85% syn- to late-tectonic plutonic rocks and two greenstone belts, the La Grande (LGGSB) and the Middle and Lower Eastmain greenstone belt (MLEGSB). The Wabamisk property overlies the west part of the Lower Eastmain greenstone belt.
The MLEGSB extends along an east-west axis for about 300 km, is 10 to 70 km wide, and is bounded to the south by a major unconformity. It is composed of volcanic and sedimentary rocks that formed in an oceanic setting with mid-oceanic ridges, oceanic plateaus and volcanic arcs. These rocks were intruded by calc-alkaline rocks ranging in composition from gabbro to monzogranite.
The MLEGSB is characterized by volcanic rocks of the Eastmain Group, which is subdivided into 4 volcanic cycles and 5 formations(Boily and Moukhsil, 2003). The Kauputauch Formation forms the first volcanic cycle (2752-2739 Ma) and is composed of massive to pillowed flows of tholeiitic metabasalts and andesitic basalts, and felsic flows overlain by a sequence of felsic to mafic tuffs.
The Natel Formation is part of the second volcanic cycle (2739-2720 Ma) and is composed of komatiite, komatiitic basalt, and massive to pillowed tholeiitic basalt and andesite.
The Anatacau-Pivert Formation, which occurs in the project area, forms the third volcanic cycle (2720-2705 Ma). This formation is composed of metabasalt, amphibolitized andesite, rhyolite and tuff. The entire assemblage is overlain by sedimentary rocks including siltslate, mudslate, wacke and conglomerate. Volcanic activity in this cycle was accompanied by moderate, mainly syntectonic plutonism.
The Komo and Kasak formations, which represent the fourth and last volcanic cycle (<2705 Ma), mainly consist of massive or pillowed basalts, komatiitic basalts and minor andesite. These rocks are amphibolitized and have a tholeiitic affinity. Minor units of felsic ash tuff are intercalated in this formation. Calc-alkaline felsic lapilli tuffs also alternate with minor amounts of mafic tuff (Moukhsil and Doucet, 1999).
Two periods of sedimentation occurred after these volcanic cycles, and were accompanied by various episodes of plutonic magmatism. The Wabamisk Formation (>2705 Ma) was deposited during the first period of sedimentation. Its base is composed of volcaniclastic layers, with andesitic lapilli tuffs and beds of crystal tuff, polygenic blocky tuff, mafic to felsic blocky tuff, ash tuff and crystal tuff. The top of the Wabamisk Formation consists of polygenic conglomerate dominated by tonalitic pebbles and another unit of polygenic to monogenic conglomerate with diorite and granodiorite pebbles, interbedded with sandstone beds, tuff layers and iron formations. According to Moukhsil et al. (2003), the Wabamisk Formation overlies the older rocks in erosional discordance.
The dominantly metasedimentary Auclair Formation (<2648 ±50 Ma), formed during the second sedimentary period, is dominated by paragneiss. Most of the paragneiss (80%) is derived from greywacke, with the balance

derived largely from pelite. The Auclair Formation is interpreted as the weakly metamorphosed equivalent of metatexites of the Laguiche Basin in the Opinaca subprovince.
Tonalitic to granodioritic plutons are grouped into three categories, synvolcanic, syntectonic, or post- to late-tectonic. Gabbro dykes crosscut all of the above.
Previous work conducted in the MLEGSB outlined three phases of deformation. The first (D1) is characterized by an E-W-trending schistosity ranging in age from 2710 to 2697 Ma. The second phase of deformation (D2) is marked by a NE-SW-trending schistosity which is broadly N-S in many locations, the age of which is estimated between 2668 and 2706 Ma. The third phase of deformation (D3) affects syn- to post-tectonic intrusions and is less penetrative and thus not as obvious on a regional scale. It is mostly visible in metasedimentary rocks in the form of a WNW-ESE to NW-SE-trending schistosity. This last deformation event is dated at <2688 Ma, which corresponds to the age of metamorphism. Given the age of the Nemiscau subprovince (<2697 Ma), it is unlikely to bear traces of the first phase of deformation (D1) recognized in the MLEGSB.

7.2. Property Geology
Mapping conducted from 2006 to 2012 has improved the understanding of the lithologies on the Wabamisk property (Figure 4). The mapping of outcrops during this time allowed Virginia to refine the geology of the property within the framework proposed by geologists of the provincial government (Moukhsil, 2000). The geology of the property is summarized below from stratigraphic base to top. The regional metamorphic grade observed in volcanic and sedimentary rocks on the Wabamisk property is generally the amphibolite facies and the greenschist facies.
The Anatacau-Pivert Formation forms a NE-SW oriented band across the SE part of the main block of the property. On the adjacent Opinaca property to the east the sheared contact zone between amphibolitized basalt and siliciclastic rocks at the top of the formation hosts significant gold mineralization that occurs in several zones. On the adjacent Wabamisk property, only a few gold showings have been found to date in rhyolite and rhyodacite (Lac H volcanic complex) and siltslate, mudslate and chert. Trenching and mapping by Virginia Mines has revealed the presence of abundant mafic lava, gabbro, siltslate, mudslate and felsic lava in the Anatacau-Pivert Formation. Other subordinate lithologies such as lapilli tuff, arenite, mudrock, exhalite, ultramafic intrusives and QFP dykes were also recognized.
The Wabamisk Formation forms a NW-SE oriented belt across the NW part of the property. This formation is characterised by mafic lavas, intermediate to felsic tuff and sedimentary rocks ranging from conglomerate to arkose. According the government the younging direction is from the north to south, passing from amphibolitized basalt and intermediate tuff to felsic tuff up-section.
The sedimentary Auclair Formation consists of paragneiss and weakly metamorphosed sedimentary rocks such as arenite, wacke and iron formation. It forms a large crescent-shaped band across the property. Most of the gold mineralization on the property occurs within rocks of this formation.
Plutonic bodies of varying age occur along outboard areas and margins of the property, and in general these bodies were not routinely mapped by Virginia Mines’ geologists. For instance, the core of the Aupiskach tonalitic intrusive in the south part of the project area was not mapped, although its granodioritic rim was investigated along the contact with the Anatacau-Pivert Formation. The Kapiwak pluton was observed in rocks adjacent to the Auclair Formation in the western part of the property. The Kawachusi pluton is present at the north contact of the Wabamisk Formation and it marks the northern limit of the property.
Mapping by Virginia geologists has over the years refined the nature and position of geological contacts presented on the government maps to reveal that sedimentary rocks are probably more abundant than previously reported. The geology of the property has also been reinterpreted using a high definition magnetic airborne survey. The Virginia interpretation, as shown in Figure 4, recognizes the existence of a folded package of interlayered siliciclastic metasedimentary rocks (greywacke, siltstone, mudstone, arenite and conglomerate), iron formation and gabbro across the central part of the property.
Gold occurs almost exclusively in quartz veins accompanied by locally intense alteration that formed varying amounts of quartz, sericite, feldspar, chlorite, biotite and tourmaline. Some gold also occurs in the altered host-rocks which consist predominantly of greywacke and arenite. Veins and host-rocks are deformed and show evidence of N-S shortening accompanied by transposition. This deformation gives rise to folded veins and/or boudinage along transposition planes. Not all veins have undergone the same degree of deformation. Some early veins are strongly dismembered, whereas later veins show little evidence of deformation.

7.3 Mineralization
Several different types of mineral occurrences are reported in the MLEGSB (Moukhsil and al., 2002; Gauthier and Laroque, 1998). They may be classified according to their genetic model and age of emplacement as follows: 1) synvolcanic mineralization (2710-2752 Ma), 2) syntectonic mineralization (2697-2710 Ma), and 3) post-tectonic mineralization (~2687 Ma).
Synvolcanic occurrences represent nearly 50% of known showings in the MLEGSB, and include sulphide-facies iron formations (Fe, Cu, Au, Ag), volcanogenic showings (Cu, Zn, Ag, Au), and magmatic showings such as porphyry-mantos-type (Cu, Au, Ag, Mo) and epithermal (Au, Ag, Cu, Zn, Pb).
Virginia Mines

Wabamisk Project

Syntectonic occurrences represent slightly more than 40% of known showings and include orogenic deposits Au, As, Sb) related to D1 and D2 phases of deformation. This category also includes gold deposits associated with oxide- or silicate-facies iron formation (Au, As). Finally, the few post-tectonic occurrences that are present correspond to lithium- or molybdenum-enriched pegmatites.
Mineralization is widespread on the Wabamisk property. Pyrrhotite and arsenopyrite are the most common sulphide minerals, followed by pyrite, locally occurring in significant concentrations. Chalcopyrite and bornite were observed in a few locations. Sulphides occur in all mapped units, whether sedimentary, volcanic, or intrusive in origin. Sulphides generally occur as disseminations, replacements and occasionally as thin mm- to cm-scale veins and veinlets.
In iron formation, pyrrhotite is the dominant iron sulphide (<25%) followed by pyrite. Mafic lavas contain more pyrite than pyrrhotite. Disseminated arsenopyrite (<10%) occurs mostly in metasedimentary rock in the north-central part of the property. Very high arsenopyrite percentages are occasionally observed in mafic lavas and tuffs associated with QFP dykes and quartz-tourmaline veins. Most gold anomalies are associated with mafic lavas or metasedimentary units that have been cross-cut by quartz veins and veinlets.
The Isabelle showing, discovered by Virginia Mines in 2007, consists of a series of parallel, steeply-dipping, N-S striking laminated fault-fill quartz veins in a fine- to coarse-grained greywacke. The gold-bearing veins are contained in an envelope that is 10-20 m thick that has been exposed at surface over a strike length of 80 m (Poitras, 2010). Very little sulphide mineralization (<1% pyrrhotite, pyrite and chalcopyrite) is associated with gold mineralization. Visible gold is common. The greywacke is cross-cut by syn-deformation and syn-mineralization feldspar porphyry dykes up to 4 m thick. Some of the best gold grades occur in quartz veins cross-cutting the feldspar porphyry. The mineralized sedimentary rock is in faulted contact with metabasalts to the west and an intrusive contact with an undeformed granodiorite-tonalite pluton to the east. Down-dip mineral lineations observed on the walls of the gold-bearing veins indicate emplacement in a reverse fault. This faulting event has also created folds with horizontal fold hinges. The veins were subsequently folded to create tight folds with vertical fold hinges. These two orthogonal deformation events created distinct, circular interference patterns in the fine-grained sedimentary rocks (Poitras, 2010). Moderate to weak biotite alteration is observed in the wall rock adjacent to the gold bearing quartz veins and weak to moderate garnet alteration is observed in the hanging wall of the steeply east-dipping zone.
The Main Stripped area at Wabamisk was the most significant mineralization zone discovered during the summer of 2012 by Virginia Mines, and was the focus of the winter 2013 drill program. Visible gold in quartz veins and in altered wacke was identified over a lateral distance of 850 metres within this system, which remains open towards the east, west and at depth. The gold mineralization consists of variably deformed generations of veins occurring within folded metasedimentary rocks. The centimetre- to metre-scale quartz veins are locally accompanied by an envelope of alteration several centimetres to a few metres wide composed of quartz-feldspar-sericite-chlorite. This alteration assemblage confers a bleached and locally banded and fragmented texture to the greywacke. The mineralization is structurally controlled and formed in sheared and foliated zones, fractures, stockworks, breccias and fold hinges. Pyrrhotite is the dominant sulphide mineral followed by arsenopyrite and pyrite. Locally, traces of chalcopyrite were found. Very little sulphide mineralization is present in the quartz veins (<3%). Disseminated mineralization up to 15% occurs mainly in vein walls and pervasively in the greywacke near the veins. Pyrrhotite occurs as fine millimetre-scale stringers parallel to the main schistosity. Arsenopyrite is localized mainly in the walls of gold-bearing veins, but trace to 10% arsenopyrite locally occurs as disseminated grains along the main schistosity. It is usually found as hypidiomorphic to idiomorphic crystals greater than 0.25 mm in diameter. Pressure shadows created by these grains are filled by pyrrhotite. When mineralization is found in quartz veins, it often forms clusters. Disseminated mineralization occurs in different modes including replacements and in breccia, stockwork, clusters, veins and veinlets.
Gold occurs as isolated to clustered grains and more rarely as veinlets up to a few millimetres long. It is found in quartz veins at the contact between altered wall rock and the vein itself. In some cases, gold is directly associated with arsenopyrite, either enclosed in the grains of sulphide or surrounding them. In the Mustang vein, gold grains locally form trains of between 5 to 30 grains in the main schistosity plane and parallel to the chlorite-sericite laminae in the quartz vein.

ITEM 8 DEPOSIT TYPES
Orogenic lode-gold mineralization is the main deposit type being sought by Virginia Mines on the Wabamisk property. Although these deposits can occur in any lithology, the exploration program paid particular attention to sedimentary rocks given that both the Éléonore deposit and the Isabelle zone occur in greywacke. The primary exploration targets are fault zones and theses are targeted using lineaments analysis on regional magnetic surveys, topographic maps and satellite images. Other targets include bends in regional foliation, lithological contacts, borders of intrusions, metamorphic gradients and contacts between sub-provinces. It is important to bear in mind that in orogenic systems, there may be coexistence of sterile veins and auriferous veins. Thus sampling all the veins is essential.
Cu-Au porphyry deposits are the secondary deposit type being investigated on the Wabamisk property. Several Cu-Au ± Ag veins have been identified in the northern and central portions of the property which are spatially related to feldspar porphyry dykes and or intrusions. No clear genetic relation has been established between mineralization and intrusive bodies. Exploration targeting for this type of deposit involves the identification of potassic alteration and major fault zones. For both types of deposit exploration by Virginia Mines is heavily dependent on foot traverses, grab and boulder sampling and outcrop descriptions. Once a gold showing has been identified exploration then proceeds with stripping, channel sampling, detailed mapping and drilling.
ITEM 9 EXPLORATION
During the month of January 2013 two grids totalling 102.2 line-kilometres were cut on the property to facilitate future IP surveys, prospecting and mapping (Figure 5). The lines were spaced at 200 m intervals. One grid was cut to extend the existing Wabamisk grid to the NE, and the other to extend the Wabamisk grid southwestward to the north of Anatacau Lake.
During February and March of 2013 Abitibi Geophysics of Val-d’Or completed an 89.3 line-kilometre pole-dipole IP survey on these two new grids. One hundred and thirteen IP anomalies were interpreted from the data by Martin Dubois, geo, B.Sc., senior geophysicist with Abitibi Geophysics. This data was used to guide the summer 2013 trenching campaign. Details of this campaign and the IP survey are filed as separate reports.
The 2013 Wabamisk exploration program, which was undertaken from the beginning of July to the middle of October, consisted of prospecting, trenching and channel sampling, till sampling and whole-rock sampling. This work was for the most part carried out on the central part of the 2012 grid, the NW extension of the Wabamisk grid and in an area adjacent to the western part of the NW grid. In addition, a geological map at the scale of 1:2500 was completed in an area centered on the Main Stripped zone gold mineralization exposed by trenching in 2012. This work, the subject of a M.Sc. A. study undertaken by Anne-Marie Beauchamp at INRS in Québec City under the direction of doctors Benoit Dubé and Michel Malo, will not be discussed further in this report.
Exploration work during the summer was supervised by geologists Francis Chartrand and Jérôme Lavoie. Geologist Isabelle Roy and trainee geologists Tonny Girard and Simon Hébert supervised the late summer and fall portions of the program during which time the whole-rock and till surveys were completed. These five are full-time employees of Virginia Mines. Trainee geologists Anne-Marie Beauchamp, Audrey Roussel-Lallier, Jean-François Dupuis, Antoine Fecteau, Charles Gaumond and Julien Avard were involved with the project as well. The geology students that worked on the project were Émilie Gosselin, Alexandre Martel, Alexandre Rodrique and Jeanne Lavoie. Technical and logistical support was supervised by David De Champlain, assisted by Paul-Émile Poirier, Martin Gagnon and trainee Sebastian Forget. Marie-Pier Savard and Alain Piché worked as the cooks. Helicopter support was provided by Héli-Explore of La Sarre, Québec and Wapchiwem Helicopters of Radisson, Quebec. Finally, the excavator used to dig the trenches was provided by Felco Excavation from St-Félicien, Québec.
Note that the exploration work was interrupted from July 4th to July 10th when the camp was evacuated as a safety precaution due to the intense forest fires that burned through the general area.

Assay certificates from prospecting grab samples, whole-rock samples and channel samples are presented in Appendix 3. Outcrop and boulder descriptions are summarized in Appendix 4. Grab sample descriptions are presented in Appendix 5, while their analytical results are found in Appendix 6. Channel sample descriptions in the form of logs are found in Appendix 7, while their analytical results are shown in Appendix 8. Results of the till survey are found in Appendix 9. WRA sample descriptions and analytical results are presented in appendices 10 and 11, respectively. Process charts for the gold standards used during the campaign are presented in Appendix 12, while the gold concentrations in the blanks are shown in Appendix 13.
During the prospecting phase, a total of 850 grab samples for gold and multi-element analyses were collected from 718 outcrops and 47 boulders (figures 6 and 7, maps 1, 2 and 4). The most significant values (greater than 1.0 g/t Au) obtained by prospecting are presented in Table 2.
A total of 47 trenches were excavated during the summer (Figure 8, figures 11-15, 17 to xxx and Map 3). Seven of these were extensions of trenches that had been previously excavated by Virginia Mines during earlier campaigns. These trenches cover an area of 17085 m2. In all, 1600 samples were collected from 1526.5 m of channels in these trenches. Most of the samples were 1 m in length. Trench location and channel parameters are presented in tables 3 and 4, respectively. The most significant results for gold are presented in Table 5.
A few days prospecting was also done by helicopter on the block of claims to the NE of the main property just to the north of the Eastmain River, as well as on another block at the southern limit of the property. This work was done to see if sedimentary rocks similar to those that host the gold mineralization at Wabamisk were present.
An orientation till survey and a whole-rock survey were also undertaken during the latter part of the summer and into the early fall. The till was sampled in five areas down-ice from existing gold showings (Figure 9). For the till survey a total of 223 till samples of 1-kg each were analyzed for gold and multi-elements (Map 6). Gold grains in the till samples were also counted and described. Lastly, 180 samples of unaltered or least-altered rock for whole-rock analysis were taken more-or-less systematically across the property (Figure 7 and Map 5).

9.1 Prospecting, outcrop and boulder sampling
A total of 850 grab samples for gold and multi-element analyses were collected from 718 outcrops and 47 boulders (figures 6 and 7, maps 1, 2 and 4). The most significant values (greater than 1.0 g/t Au) are presented in Table 2. Prospecting was undertaken in three main areas during the summer and fall of 2013, on the central portion of the 2012 grid, on part of the 2013NW grid, and an area to the SW of the 2013NW grid. It was the latter prospecting that resulted in the discovery of part of the new gold-bearing trend, the CIT corridor (an acronym for new showing’s names, Challenger-Interceptor-Trailblazer). The location of outcrops, boulders and samples are shown on figures 6 and 7 and on maps 1, 2 and 4 (in pocket). In order to streamline the rock description, the prefix “meta” will be dropped from the rock names from herein.
The rocks on the 2012 and 2013 cut-line grids have been metamorphosed to the greenschist facies and, moving to the west, to the amphibolite facies. Multiple generations of folds and faults have affected the rocks in the area. In general, the bedding and S1, which are oriented in a more-or less NW-SE direction, have been refolded, transposed and faulted along a NE-SW direction. Thus, the dominant rock fabric (long axes of cobbles and pebbles, the dominant schistosity SP, P2 axial planes, transposition planes) are oriented at 250o with steep dips to the north. A third phase of folding, manifesting itself as a crenulation cleavage and open folds, are locally observed.
For the most part, the rocks encountered during prospecting in 2013 were dominated by sedimentary units, specifically greywacke with lesser siltstone, arenite, conglomerate and iron-rich siliceous beds. These rocks are intercalated with basaltic lava and injected by gabbroic to pyroxenitic sills and dykes that very in thickness from less than 1 m to several metres. There are also minor intrusions of diorite locally present on the NW grid.
The greywackes occur as massive to graded beds that form homogeneous sequences, as well as occurring with intercalations of arenite and siltstone. Bedding varies in thickness from the m-scale down to the cm-scale and thinner, forming laminations. Bedding structures such as grading, cross-bedding and erosional surfaces are locally present. The greywackes are composed of detrital monocrystalline and polycrystalline quartz, feldspar and minor lithic fragments in a fine-grained matrix now composed of chlorite, biotite, white mica, epidote and Fe-Ti opaques. The arenites have essentially the same mineralogy as the greywackes but with more feldspar in the framework and less matrix. Very minor quantities of disseminated iron sulfides are generally present in the rock as well.
The siltstones are composed of fine- to very-fine grained quartz, feldspar, biotite and white mica in a clay matrix. They are generally homogeneous and locally interbedded with thin argillite horizons. The conglomerates are polygenic and for the most matrix-supported. The fragments are dominated by felsic and mafic rock. Minor disseminated iron sulfides are present in most of the beds, imparting a rust-coloured stain to the rock. The conglomeratic beds also show the effects of deformation, as the fragments are flattened parallel to the dominant schistosity plane. The conglomerates are most common on the 2013NW grid where they form a discontinuous band oriented NE-SW.
The mafic rocks are generally composed of medium-grained actinolite, chlorite, plagioclase and opaque minerals (Fe-Ti oxides, Fe-sulfides). They are generally massive and foliated, with deformed pillows occurring locally.
At least three generations of quartz veins were observed, early veins that are subparallel to straight and folded bedding, axial plane veins that are almost always straight, and late veins that occur with minor faults that cut the older veins. Subhorizontal veins are also present, but their relationship with the other veins is unclear.
As mentioned above, the host rocks of the quartz veins are locally altered. Siliciclastic rocks such as the greywackes tend to be less altered than the more reactive mafic rocks. In any case the alteration appears to be limited to a few cm to dm around the veins depending on the thickness of the quartz vein. The most common alteration appears to be silicification. Other alteration minerals include actinolite, sericite, biotite and tourmaline. Disseminated pyrrhotite, pyrite and arsenopyrite also form with these silicates. Arsenopyrite in particular appears to be associated with gold mineralization, forming mm-scale idioblastic crystals that compose up to 20% of the alteration envelope around the vein. An assemblage of actinolite-garnet-feldspar-carbonate also forms discontinuous bands parallel to bedding, and thus appears to be a more widespread type of alteration.

Of the 850 grab samples taken on the Wabamisk property this summer, 281 had gold values above the detection limit of 5 ppb Au. Of these, 29 had gold values greater than 0.25 g/t, and of the latter group 12 had values above 1.0 g/t Au. The highest gold value, 278 g/t Au, came from a sample of a quartz vein with visible gold at the Challenger showing.
Several new significant gold showings were discovered in 2013 just to the north of Lake Nikawin. These are aligned along a 2.75 km long E-W axis that is called the CIT corridor. Three main showings, each with visible gold grains, comprise the corridor, the Challenger and Interceptor showings to the west, and the Trailblazer showing to the east. These showings occur in the same general area as a few other older showing discovered by Virginia Mines over the past few years. Together, these showings form a lineament over 5.75 km long.
The Challenger showing (Figure 10, photo 1) was discovered by prospecting in the latter part of the summer of 2013. It is composed of several dm- to m-scale quartz veins that are oriented SW-NE and that dip steeply to the north for the most part. The veins are injected parallel and subparallel to the schistosity planes of the greywacke, which is the dominant host-rock. The veins are discontinuous along the injection planes, where they pinch and swell to form pods several metres in length. One of these veins has scores of fine- to locally medium-grained gold disseminations. This vein measures over 7 m long by 20 cm thick. Gold samples such as these are responsible for the Bonanza-style grades up to 278 g/t Au (364347) in grab samples. Other grades are less spectacular, ranging from several 10s of grams per tonne down to sub-gram values. Within a few decimeters of the veins the host greywacke is partially altered to quartz-sericite-actinolite-chlorite, with minor quantities of pyrrhotite-arsenopyrite occurring as finely disseminated grains.
The Challenger showing was mechanically stripped in the late summer. The results will be discussed below in the section concerned with trenches.
The Interceptor showing lies approximately 300 m to the east of the Challenger showing (Figure 10, photos 2 and 5). The Interceptor showing consists of a m-scale gold-bearing quartz vein that occurs in greywacke. An alteration zone composed of sericite, actinolite, chlorite, pyrrhotite and arsenopyrite encloses the vein. A few gold grains were observed in the quartz vein. Together the vein and the alteration envelope are up to 2.5 m thick, and extend for several tens of metres along strike. The best gold grade, at 8.63 g/t, came from sample 362967 to the east of the stripped zone. This showing was also mechanically stripped.
The third significant mineralized zone discovered in 2013 was the Trailblazer showing (Figure 11, photos 3 and 4. Grab samples from an irregular, folded dm-scale quartz vein that occurs at the contact between gabbro to the north and greywacke to the south returned values up to 29.7 g /t Au (360436). The vein was observed for several tens of metres before disappearing under overburden. The vein shows laminar structure (Photo 4) and locally hosts scores of disseminated gold grains varying in size from fine- to medium-grained. The alteration assemblage around the vein is dominated by biotite and pyrrhotite and arsenopyrite. Other similar textured veins also occur nearby on the same outcrop.

9.2 Trenching and channel sampling
A total of 47 trenches and stripped zones were excavated during the 2013 exploration campaign (Figure 8, figures 11- xxx and Map 3). Of these seven were extensions of trenches that had been previously excavated by Virginia Mines during earlier campaigns. In all the trenches cover an area of 17085 m2. A total of 1600 samples were collected from 1526.5 m of channels in these trenches. In all there are 225 channel samples and saw-cut grabs. Most of the samples were 1 m in length.
Trench location and channel parameters are presented in tables 3 and 4, respectively. The most significant results for gold are presented in Table 5. These excavations targeted certain IP anomalies, extensions of known gold-bearing structures and new showings discovered in 2013 such as the Challenger, Interceptor and Trailblazer showings. Unfortunately due to time constraints only one of the excavated zones was mapped in detail. Instead work focused on channel sampling.
For the most part, the excavations revealed the presence of greywacke and other sedimentary units such as siltstone, arenite and conglomerate. Mafic rock such as gabbro and basalt are also present locally. These rocks are locally cut by dm- to m-scale quartz veins that in some instances are gold-bearing. Sterile veins tend to be massive and milky white in colour. The IP anomalies were usually explained by the presence of disseminated sulfide zones (pyrrhotite and more rarely arsenopyrite) in sedimentary horizons as well as in fault and shear zones.

Table 5 – Channel samples with more than 1 g/t Au
Out of the 1600 samples 541 were at or below the 5 ppb detection limit for gold. From the 1059 sample that had detectable gold 77 had gold values above 0.25 g/t and of these 26 had values above 1.0 g/t. The highest values, 351 g/t Au (364453) and 169.5 g/t Au (364454) were samples with visible gold from the Trailblazer showing. The other Bonanza sample, 107.5 g/t Au, came from a sample of quartz vein with visible gold in WB2011TR002-EXT, and is part of the Boomerang showing discovered in 2010.
Four trenches will be discussed below; three in the CIT corridor as well as one which extended WB2012TR015 so as to expose the interval of 6.06 g/t Au over 3.2 m that was collared by borehole WB-13-025.
9.2.1 Trench WB2013TR035, the Trailblazer showing
This stripped zone was excavated to expose the gold-bearing quartz vein that was discovered during the summer (figures 11 and 12). The excavation revealed the presence of a dm-scale, irregular quartz vein with complex, bifurcating geometry at or near the irregular contact of a mafic sill or dyke (photos 3 and 4). Despite the seemingly complex nature of the veins the principal vein appears to be present for approximately 50 m along a NW-SE direction before disappearing under the overburden.
Despite the presence of a grab sample of 29.7 g/t Au (360436) and saw-cut grab samples of 351 g/t Au (364453), the best result from channel sampling returned 3.85 g/t Au over 0.7 m (364442). This suggests that the gold was precipitated in the veins and along narrow vein selvedges.

Figure 12 – Channel and grab samples from the Trailblazer showing, trench WB2013TR035
9.2.2 Trench WB2013TR039, the Challenger showing
This trench was excavated to expose the gold-bearing vein that returned bonanza grades with scores of visible gold grains (figures 11 and 13). Despite the presence of Bonanza grades up to 278 g/t Au in grab samples (364347), no channel samples returned comparable values. In fact, the best grade was 5.67 g/t Au over 1.0 m from channel WB2013TR039-R1 (364510). However, the altered greywacke wall rocks that enclose this vein are highly anomalous in gold, returning 0.25 g/t over 8.0 m (open, WB2013TR039-R1) and 0.35 g/t Au over 4.0 m (WB2013TR039-R2). This suggests that a more penetrative style of gold mineralization is present in the Challenger showing.

9.2.3 The Interceptor showing, trench WB2013TR040
This trench was excavated to expose the m-scale quartz vein with visible gold of the Interceptor showing (figures 11 and 14). This vein is folded and dislocated, and incorporates several slices of the altered greywacke that forms the wall rock (Photo 5). Unfortunately, despite the presence of visible gold, the best channel sample returned a value of 2.48 g/t Au over 0.9 m (364492) from channel WB2013TR040-R4. However, as is the case for the Challenger showing, the wall rock appears to be anomalous in gold, with values up to 0.332 g/t Au.

9.2.4 WB2012TR015-Ext
Drillhole WB-13-025 intersected a near-surface gold zone that graded 6.06 g/t Au over 3.2 m in a quartz vein within altered greywacke. The surface projection of this intersection proved to be immediately to the north of trench WB2012TR015. This trench was extended to the north, west and east so as to expose the vein at surface (Figure 15).
At surface this zone returned a comparable value of 5.7 g/t Au over 2.0 m. The gold-bearing structure is a deformed laminated semi-transparent quartz vein with enclosed fragments of altered greywacke (Photo 6). Adjacent to the vein the greywacke is partially altered to actinolite and sericite. There are other sterile quartz veins exposed in the trench but they are typically massive and milky-white. The gold-bearing vein is similar in structure and composition to a dm-scale vein occurring at the south end of the trench that returned 4.98 g/t Au over 3.0 m in 2012.

Wabamisk Project
March 2014
An orientation whole-rock survey were also undertaken during the latter part of the summer and into the early fall. 180 samples of unaltered or least-altered siliciclastic sedimentary rock (greywacke, arenite and siltstone) and lesser mafic-ultramafic igneous rock were selected for whole-rock analyses more-or-less systematically across the property (Figure 7 and Map 5). The Al2O3-TiO2 ratios were then examined and the rocks separated into 3 groups (Figure 51). With the exception of group 3, the mafic-ultramafic rocks, the TiO2-Al2O3 ratio in siliciclastic sedimentary rock can be used to qualitatively determine provenance. Groups 1 and 1A, with the lowest TiO2 values, appear to have a more granitic provenance than groups 2 and 4, which could have been derived from more mafic rocks such as andesites. Group 5 only has a few samples so not much more can be said regarding its origins.

9.4. Till survey
An orientation till survey was undertaken during the latter part of the summer and into the early fall. The till was sampled in five areas down-ice from existing gold showings (Figure 9). For the till survey a total of 223 till samples of 1-kg each were analyzed for gold and multi-elements (Map 6). Gold grains in the till samples were also counted and described.
Although results have not yet been studied in detail, it is evident that the presence of the gold showings does not appear to be reflected in the till. This suggests that the till in these areas could be exotic and not locally derived.

ITEM 11 SAMPLE PREPARATION, ANALYSES AND SECURITY
Outcrop and channel samples were collected by Virginia personnel and stored at the campsite. Samples from outcrop were collected by using a mallet and cold chisel, while channel samples were sawn with a gas-powered diamond blade rock saw. The samples were placed into plastic bags with a sample tag and then brought to the camp, where they awaited shipment to the ALS laboratory in Val-d’Or by truck. The driver of the vehicle, Pascal Morissette, is employed by Services Techniques Géonordique, a consulting firm hired on a regular basis by Virginia Mines. The channel samples were shipped to the laboratory in batches of 20.
Gold was analyzed by fire assay fusion/atomic absorption, the Au-AA23 method of ALSCHEMEX laboratories, when the presence of coarse grained gold was not anticipated. These samples were crushed in their entirety at the ALS Minerals preparation laboratory in Val-d’Or to >70% passing 2 mm (10 mesh; ALS Minerals procedure CRU-31). A 200- to 250-g sub-sample was obtained after splitting the finer material (< 2 mm). The split portion derived from the crushing process was pulverized using a ring mill to > 85% passing 75 µm (200 mesh - ALS Minerals procedure PUL-31). From each such pulp, a 100-g sub-sample was obtained from another splitting and shipped to the ALS Minerals laboratory for assay, typically on a 30 gram sample. For the samples with the values higher than 10 g/t Au, the analysis was repeated with the Au-GRA21 procedure (AAS followed by gravimetric finish). Other concentration of other elements, including Ag, Al, As, B, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, Hg, K, La, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sb, Sc, Sn, Sr, Th, Ti, Tl, U, V, W and Zn, were determined by the ME-ICP41 procedure (aqua regia digestion followed by ICP-AES analysis). The remainder of the pulp (nominally 100 to 150 g) and the rejects are held at the processing lab for future reference.
The authors are of the opinion that sample preparation, security and analytical procedures were adequate to ensure the quality of the analytical results.
ITEM 12 DATA VERIFICATION
The authors of the present report were directly involved in collecting, recording, interpreting and presenting the data in this report and in the accompanying maps and sections. Data was reviewed and checked by the authors and is believed to be accurate.
In addition to the internal quality checks used by the ALS CHEMEX laboratory, the exploration work conducted by Virginia Mines was undertaken using a quality assurance and quality control program according to industry standards for early-stage exploration projects. These procedures are essential to monitor and control (1) accuracy, (2) precision and (3) possible contamination of the samples. For this campaign, gold standards and blanks were employed to monitor the assay results of the drill core samples.
Typically, each batch of 20 consisted of sixteen channel samples, a blank and three gold standards of different grade. In all, five gold standards from Rocklabs Inc. and two standards from Analytical Solutions Limited were used during the campaign. The blank and standards were placed numbered sequence at pre-determined positions. In all, 99 blanks, 31 SH65 standards, 20 SH69 standards, 46 SK62 standards, 53 SL61 standards, 45 WG1 standards, 49 OREAS-203 standards and 53 OREAS-208 standards were used during the campaign. This represents a total of 396 quality control samples that were used to monitor 1600 channel samples analyses, or 24.75%. The Rocklabs’ reference materials used, which are composed of various mixtures of feldspar, basalt, pyrite and gold-bearing minerals, were (1) SH65, grading 1.348 g/t Au; (2) SH69, grading 1.346 g/t Au; (3) SK62, grading 4.074 g/t Au; (4) SL61, grading 5.931 g/t Au and (5) WG1, grading 1.42 g/t Au. The Analytical Solutions reference materials used, which are composed of mafic volcanic rock, were OREAS 203, grading 0.871 g/t Au and OREAS 208, grading 9.248 g/t Au. Two types of uncertified blanks were used that commonly employed in the landscaping industry, crushed limestone and crushed dolomitic limestone.

12.1 Reference material validation
The standards were used to monitor accuracy and precision. Their values were inserted into a Microsoft Excel template designed by the qualified staff at Rocklabs and interpreted according to the recommendations listed in the template and given a qualifier (good, industry typical, need improvement or something wrong). The results for each standard using the Au-AA23 method for analyzing gold are described below.
12.1.1. Standard SH65 (1.348 g/t Au)
The process charts and table results are presented in Appendix 12a-b. The precision for Au expressed as the percentage of relative standard deviation, is 4.5% (industry typical), while the accuracy expressed as the percentage difference from the assigned value is -2.5%. There are no gross outliers (good). There are no gross outliers (good).
12.1.2. Standard SH69 (1.346 g/t Au)
The process charts and table results are presented in Appendix 12c-d. The precision for Au expressed as the percentage of relative standard deviation, is 2.4% (good), while the accuracy expressed as the percentage difference from the assigned value is -2.2%. There are no gross outliers (good).
12.1.3. Standard SK62 (4.075 g/t Au)
The process charts and table results are presented in Appendix 12e-f. The precision for Au expressed as the percentage of relative standard deviation, is 3.8% (industry typical), while the accuracy expressed as the percentage difference from the assigned value is -3.6%. There are no gross outliers (good).
12.1.4. Standard SL61 (5.931 g/t Au)
The process charts and table results are presented in Appendix 12g-h. The precision for Au expressed as the percentage of relative standard deviation, is 2.4% (good), while the accuracy expressed as the percentage difference from the assigned value is -3.2%. There are no gross outliers (good).
12.1.5. Standard OREAS 203 (0.871 g/t Au)
The process chart and table results are presented in Appendix 12i-j. The precision for Au expressed as the percentage of relative standard deviation, is 3.8% (industry typical), while the accuracy expressed as the percentage difference from the assigned value is -3.8%. There is one gross outlier (industry typical) that is higher than the declared standard value. It is possible that the standard became contaminated from the previous sample (361655 at 0.288 ppm Au), but if so the contamination is limited to the standard. It is also possible that another standard such as SH65 or SL69 was used by mistake.
12.1.6. Standard OREAS 208 (9.25 g/t Au)
Virginia Mines
Page 88
Wabamisk Project
March 2014
The process charts and table results are presented in Appendix 12k-l. The precision for Au expressed as the percentage of relative standard deviation, is 4.6% (industry typical), while the accuracy expressed as the percentage difference from the assigned value is -0.1%. There are no gross outliers (good).
12.1.7 Standard WG1 (1.42 g/t Au)
The process charts and table results are presented in Appendix 12m-n. The precision for Au expressed as the percentage of relative standard deviation, is 4.7% (industry typical), while the accuracy expressed as the percentage difference from the assigned value is -2.0%. There are no gross outliers (good).
12.2 Blank validation
Blank samples were employed to monitor contamination in the laboratory. A total of 99 blank samples were inserted in the routine sampling line. All gold concentrations of the blanks are listed in Appendix 13. Assays for blanks should be less than 5 times the limit of detection of the analytical method, in this case 0.005 ppm Au for the Au-AA23 method. Therefore, the gold content in the blank sample should be less than < 0.025 g/t Au to be considered acceptable. All blank samples, except for number 363431 at 0.64 g/t Au, are under these acceptable limits so we can assume that no significant detectable contamination occurred. Samples adjacent to number 363431 have very low gold values below 0.1 ppm so no significant contamination appears to have occurred in the sample stream.

ITEM 23 ADJACENT PROPERTIES
The Wabamisk project is adjacent to the north, northeast and west to the Anatacau project. The Anatacau 207map-designated claims, totalling 10 952.03 hectares (109.52 km2), are 100% held by IAMGOLD-Québec Management Inc. Under an agreement with Virginia Mines Inc., the latter may earn 100% interest in the project by investing 3 million dollars in exploration before the end of 2015. IAMGOLD retains a 2% NSR royalty, half of which (1%) may be bought back by Virginia. During the 2012 exploration program on Anatacau, samples with visible gold collected from outcrops AN2012JFD-070 and AN2012JFD-005 returned significant analytical results of27.6 g/t Au (sample 280964) and13.1 g/t Au (sample 281185) respectively (Chartrand and Beauchamp, 2013). In all, 23 samples of the 562 collected had gold values greater than 0.1 g/t including 11 with greater than 0.3 g/t Au.
The Opinaca property, under option to Virginia Mines from Ressources d’Arianne, occurs to the east of the Wabamisk project, straddling the Eastmain road towards the Hydro-Quebec installations at Eastmain-1. During the summer of 2012, three prospecting teams spent 2 days on the Opinaca property in few areas that remained relatively unexplored. Most samples collected by the teams returned Au values below detection limits. However, one sample collected from a minor quartz vein in basalt graded3.4 g/t Au. Another sample of rusty basalt returned0.48 g/t Au, 939 ppm Cu and 9630 ppm Pb.
Eastmain Resources has a property to the northeast of the Wabamisk claims that contains the historic Bear Island and Reservoir showings. Dios Exploration has the AU33 West property to the ESE of the Wabamisk property. Exploration work from 2011-2012 returned several interesting gold values from a tonalitic-granodioritic intrusive complex to the south of the EM-1 – Muskeg road. The best results were returned from the T7 trench on the Heberto showing (5.0 g/t gold over 5.25 m and 1.12 g/t gold over 4.5 m over a sheared tonalite. Several anomalous results in the order of 0.5 to 1.1 g/t gold over sections of 0.75 to 2.25 m were obtained from the other trenches. Dios Exploration property blocks also adjoin the Wabamisk and Anatacau properties to the south. Independent geologist Peter Bambic holds ground to the west of Wabamisk.
The Assini property, 100% held by Virginia Mines Inc., is adjacent to the northwest part of the Wabamisk property. During the 2012 prospecting, seven (7) samples returned anomalous values in gold or copper. The best sample, returning8.44 g/t Au and 390 ppm Cu, occurs just outside the Assini property and is actually on the adjacent Wabamisk property along the shore of the Eastmain River. A few other anomalous Au or Cu samples were found along the band of greywacke and paragneiss that lies adjacent to the volcanic belt that was the focus of exploration in previous campaigns. One of these samples occurs approximately 500 meters to the east of a 2011 sample which returned 2.5 g/t Au from a cm-scale quartz vein injected into a greywacke sequence. Another sample approximately 700 m NE of the James Bay highway returned 0.671 g/t Au from a sheared greywacke outcrop. Lastly, two samples from the eastern part of the property returned 1.12 and 1.27 g/t Au from weakly sulfidized greywacke adjacent to quartz veins. The latter two samples occur a few hundred meters to the SE of the 2011 channel sample discovery of 16.1 g/t Au. Channel samples taken near the 2011 channel samples of Assini, one of which returned 16.1 g/t Au, returned weak values with the highest being 2.68 g/t Au over 1.0 m.

ITEM 24 OTHER RELEVANT DATA AND INFORMATION
This section is not applicable to this report.
ITEM 25 INTERPRETATION AND CONCLUSIONS
The 2013 campaign was successful in discovering several new gold showings and extensions of gold mineralization discovered by earlier Virginia programs. The most significant new result was the discovery late in the summer of a gold-bearing corridor approximately 8 km to the WNW of the Mustang vein. This corridor, in which the gold showings appear to occur in two clusters at either end, is almost 3 km long along an E-W direction. Three gold showings, each with visible gold grains, occur in the corridor. They are, from west to east, the Challenger, Interceptor and Trailblazer showings.
In the case of the Challenger and Trailblazer showings, scores of fine gold grains were locally observed in the veins. The gold occurs in quartz veins, quartz veinlets and to some extent the enclosing altered greywacke wall rock. For the most part, the host rocks consist of fresh fine to medium grained greywacke which becomes variably silicified, sericitized and chloritized as the veins are approached. Actinolite and tourmaline are also present. The altered greywacke is also sulfidized, and disseminated pyrite, pyrrhotite and arsenopyrite form up to 7.5% of the rock. Native gold occurs as fine to medium grains in the quartz vein and adjacent wall rock. Locally, several dozen gold grains may be observed in hand sample, and grab samples returned values of up to 278 g/t Au (364347) and 351 g/t Au (364453). Channel samples, however, returned more modest values up to 5.67 g/t Au (364510) over 1.0 m.
The 2013 campaign was also successful in increasing the extent of gold showings that had been previously discovered by Virginia Mines, such as the Powerline and adjacent showings discovered in 2009 and 2011. These gold-bearing veins occur in greywacke, gabbro and conglomerate to the east of the new gold corridor, and may in fact represent its continuation to the east. If so, than this corridor would be almost 6 km long and become a significant new target for exploration in the future.
In almost all cases the gold mineralization is associated with centimeter- to meter-scale quartz veins that transect and pervade greywacke and to a lesser extent arenite and siltstone. When gold occurs in the wall rock, quartz veinlets are almost always present. However, anomalous gold values found in the altered wall rocks of the Challenger and Interceptor showings may represent a more penetrative style of mineralization. This style of mineralization may also have been discovered in 2013 on the adjacent Anatacau property.
ITEM 26 RECOMMENDATIONS
Given that significant gold mineralization discovered in the CIT corridor, and that the mineralization appears to be open at either end and at depth, a few diamond boreholes should be drilled to test for mineralization at Challenger, Interceptor and Trailblazer. A first-pass program should test down to approximately 50 m depth. These holes could be done at the same time as a second-pass borehole program that should be done on the Mustang vein and Main Stripped zone areas to continue the drilling that was stared in the winter of 2013.
Secondly, since most of the corridor lies outside the 2013 IP survey, the area to the west of the 2013 NW grid should also be covered by a pole-dipole IP survey with 200 m line spacing. This area should also be prospected in detail during the summer of 2014. Trenching of IP anomalies and gold showings discovered in 2014 should also be trenched and channel sampled.
