For each 10 cents of a dollar over US $1.50 of the international price for one pound of copper, we will increase on 1% COMIBOL'S share up to a ceiling of 22% of the operational cash flow's share (e.g.: for US$ 1.60 for one pound copper, COMIBOL'S share will be 16%, for US$ 1.70 it will be 17%, etc.). ===== The advantage of applying this scale as a function of the market's price for copper is that COMIBOL'S share improves when the project by itself considers it feasible; that is to say, improves COMIBOL'S share whilst at the same time the company's situation improves. ===== ASC BOLIVIA LDC does not wish to speculate and we do not refuse to offer fixed share percentages before knowing the results from the feasibility study; we think that it should be clear that our wish is to offer COMIBOL a substantial share when the market conditions so allow. ===== SEAL: Legal Advisory COMIBO.- It is a faithful copy of the original.- La Paz, 13 Sept. 1996.- Signed: Dr. Jorge Eyzaguirre Duran.- RUC 02199106.- C.

Depending on the results it will be decided whether or not to continue with exploration works during the second year. ===== The First Phase will be divided in three stages: Stage 1 will include a prospection visit, rocks outcrops mapping and sampling; Stage 2 will consist of the enabling and ventilation of old mining workings, soil geochemistry, geophysics of trenches; finally Stage 3 will include primary drillings using reverse circulation, metallurgical tests and a pre-feasibility conceptual study. ===== We propose to gradually perform the following tasks: ===== YEAR 1: Mapping, sampling, geochemistry/geophysics. ===== YEAR 2: Trenches, preliminary drilling, metallurgical tests and pre-feasibility study. ===== A field team will be working permanently during Year one and a second team will be added in Year two for the start and continuation of the drilling if we decide to continue with more than one concession. ===== Apart from the geological field work to be completed during Year one of the First Phase, we will pay greater attention in the neighboring areas to COMIBOL'S concessions with the objective of obtaining new concessions in case that the results of the exploration done so justify. ===== FIRST PHASE IN COBRIZOS AND REINTEGRO.- In July nineteen ninety five, our company signed an agreement with the Litoral Cooperative in order to explore the Cobrizos concession in the understanding that this Cooperative had a lease CONTRACT in force with COMIBOL. Based on this agreement we have completed Stage One of the exploration program of the First Phase for Cobrizos. It will be required to execute Stage One in Reintegro and then the program will continue until the First Phase is completed in both concessions. ===== FIRST PHASE IN THE REMAINING CONCESSIONS.- The exploration in the other concession (Ines, Kohollpani, Puntialls, Santo Tomas and Santo Tomas II), will start after the mapping/sampling is done in Reintegro.- The team will got to the extreme southwest and will start the geological mapping and sampling in Santo Tomas, then in Santo Tomas II, Ines, Puntillas and finally Kohollpani. All this work will be done during the first year. ===== Where the results from the first year work be favorable, we will continue with the next exploration stages programmed for the First Phase, otherwise the property(ies) will be rejected. ===== Chart No. 1 shows a general chronogram for the execution of the works programmed. =============================== 24 "A S C B O L I V A L D C" CHART NO. 1 GENERAL CHRONOGRAM *********************************************************************************************************************************** CONCESSIONS FIRST PHASE: SECOND PHASE: THIRD PHASE: NAME/ACTIVITY EXPLORATION FEASIBILITY DEVELOPMENT YEAR 1 YEAR 2 YEAR 1 YEAR 2 YEAR 1 YEAR 2 - ----------------------------------------------------------------------------------------------------------------------------------- COBRIZOS MAPPING done SAMPLING partially done REHABILITATION OF GALLERIES X GEOCHEMISTRY done GEOPHYSICS/TRENCHES X PRELIMINARY DRILLINGS X METALLURGICAL TESTS X PRE-FEASIBILITY X DRILLING TO TEST RESERVES X FEASIBILITY X FINANCING X START OF DEVELOPMENT X - ---------------------------------------------------------------------------------------------------------------------------------- REINTEGRO MAPPING X SAMPLING X REHABILITATION OF GALLERIES X GEOCHEMISTRY X GEOPHYSICS/TRENCHES X PRELIMINARY DRILLINGS X METALLURGICAL TESTS X PRE-FEASIBILITY X DRILLING TO TEST RESERVES X FEASIBILITY X FINANCING X START OF DEVELOPMENT X - ----------------------------------------------------------------------------------------------------------------------------------- PUNTILLAS-INES MAPPING X SAMPLING X REHABILITATION OF GALLERIES X GEOCHEMISTRY X GEOPHYSICS/TRENCHES X PRELIMINARY DRILLINGS X METALLURGICAL TESTS X X PRE-FEASIBILITY X DRILLING TO TEST RESERVES X FEASIBILITY X FINANCING X START OF DEVELOPMENT X - ----------------------------------------------------------------------------------------------------------------------------------- SANTO TOMAS I - II MAPPING X SAMPLING X REHABILITATION OF GALLERIES X - ----------------------------------------------------------------------------------------------------------------------------------- 25 ************************************************************************************************************************************ CONCESSIONS FIRST PHASE: SECOND PHASE: THIRD PHASE: NAME/ACTIVITY EXPLORATION FEASIBILITY DEVELOPMENT YEAR 1 YEAR 2 YEAR 1 YEAR 2 YEAR 1 YEAR 2 - ----------------------------------------------------------------------------------------------------------------------------------- GEOCHEMISTRY X GEOPHYSICS/TRENCHES X PRELIMINARY DRILLINGS X METALLURGICAL TESTS X PRE-FEASIBILITY X DRILLING TO TEST RESERVES X FEASIBILITY X FINANCING X START OF DEVELOPMENT X - ----------------------------------------------------------------------------------------------------------------------------------- KOHOLLPANI MAPPING X SAMPLING X REHABILITATION OF GALLERIES X GEOCHEMISTRY X GEOPHYSICS/TRENCHES X PRELIMINARY DRILLINGS X METALLURGICAL TESTS X PRE-FEASIBILITY X DRILLING TO TEST RESERVES X FEASIBILITY X FINANCING X START OF DEVELOPMENT X - ----------------------------------------------------------------------------------------------------------------------------------- 26 WORK SCOPE, METHODOLOGY AND EXCUTORS - FIRST PHASE. ======= Using Cobrizos as an example, we proposed the following work scope: ===== MAPPING.- The geological mapping will be done at scales of 1:2,000 and 1:10,000. Where there are underground workings, the mappings will be done at a scale of 1:200. These mappings will be done by Scott McDonald, a geologist from Andean Silver, and/or Dra. Catrin Ellis Jones, geologist from MINTEC.- The mapping at Cobrizos has been finished except in areas where there are old underground workings, where the mapping will be done at a scale 1:500 after clearing and an adequate ventilation. ===== SAMPLING.- The exact nature of the sampling programs will depend on the own characteristics of each mining concession.- In some places we will sample intensively the rock outcrops; in other places the rock wall will be sampled in order to determine if dissemination exists or not.- Approximately 300 samples will be taken from the outcrops and mining workings at Cobrizos; to date, 83 samples have already been obtained, the remainder will be obtained from underground workings once they have been cleared and ventilated. Geochemical sampling programs will be executed in each concession.- Recently, at Cobrizos we have done a geochemical sampling in an area 750 x 750 meters, taking samples every 25 meters on a square grid. In total, 480 samples have been obtained that will be analyzed for Au, Ag, Cu, Pb and Zn. We propose to perform similar programs at each of the concessions of interest. These works will also be executed by geologists Scott McDonald and Catrin Ellis Jones and support personnel from MINTEC. ===== TRENCHES AND/OR GEOPHYSICS.- In areas where there are no rock outcrops, low frequency geophysical methods will be employed in order to determine the most propitious places to dig trenches, which will be mapped and sampled in detail. Also, when necessary and advisable, detailed geophysical surveys in order to direct and if possible, pinpoint the drilling objectives. ==== A local services company that has experience in similar jobs and good quality equipment, will be hired for trench digging; an alternative is Terra Ltda. That has already done several similar jobs for MINTEC's projects.- The geophysical surveys will be executed by a specialized company from Canada or U.S.A. (Val D'or, Gradient, Quantec, etc.).- The mapping and sampling will be done by the aforementioned geologists. ====== PRELIMINARY DRILLING.- For these works we will hire with priority the known drilling services company Layne Drilling; the supervision, control and samples preparation will be in charge of specialized personnel from MINTEC, the samples' chemical analysis will be done at Bondar Clegg's laboratory in Oruro or S.G.S. in La Paz; the control for these analysis will be done in prestigious laboratories in Canada or U.S.A. ====== 1,200 meters will be drilled in six wells using reverse circulation equipment in order to verify geological concepts and estimate mineral contents. Each well will have an approximate depth of 200 meters, with a 5.5" diameter and samples to be analyzed will be taken every meter. ===== METALLURGICAL TESTS.- At present we are using and will continue to do so, the services from Kappes Cassidy to perform metallurgical tests; also, should the case be, we would hire the University of Cardiff to do this work for Cobrizos and those concessions related with possible copper-silver deposits.- These laboratories will perform, at our request, cyaniding tests (cyanide leach), flotation tests, solvent extraction tests and other required mineralogical tests. ===== PRE-FEASIBILITY STUDY.- Before starting with 27 the drilling program in detail, a pre-feasibility conceptual study will be made for the Cobrizos - Reintegro projects and for any concession reaching this exploration stage.- In order to make this study, the services of Pincock Allen & Holt will be hired, who have already done similar studies for ASC Peru LDC. ==== SECOND PHASE.- With the execution of the Second Phase in Cobrizos -Reintegro, it is hoped to reach the target of delimiting a minimum of 10 million tons of reserves indicated up to 50 million tons depending on the results from the metallurgical tests and pre-feasibility analysis. At the present state of our knowledge, it is not yet possible even to estimate the reach of the Second Phase at the rest of the mining properties. ====== DRILLING TO DELIMIT RESERVES.- In order to delimit a minimum of 10 million tons, approximately 2,250 meters will be drilled with reverse circulation, distributed in 15 wells of around 150 meters deep each. Should the metallurgical tests and other results indicate that we can hope to delimit some 50 million tons, 25 wells, 200 meters deep each, will be drilled, totaling 5,000 meters of drilling of an equivalent amount depending on the nature of the deposit. ====== FEASIBILITY STUDY.- In order to perform this study, the services of Pincock Allen & Holt will be hired.- This study will be done if and when the drilling results are sufficient; otherwise more drilling and other works will be done to prepare this study during the Third Phase. ====================================== PAYMENT ------- RECEIPT FOR THE "COBRIZOS" MINING LICENSES.- DATE: La Paz, 15 March 1996.- - -------------------------------------------- NAME: CORPORATION MINERA DE BOLIVIA.- Register No. 03.- TRADE NAME: GRUPO MINERO NOR LIPEZ.- Address: Potosi.- KEYS: 526.0.4.- 1165.0.5.- 1123.0.0.- TAX CODE.- 1105.0.7. ===== DETAILS: Payment for mining licenses call CONCESSION: 25 de Julio.- Aguilar.- Alianza.- Bolivar.- COBRIZOS.- Copacabana.- - ----------- Don Bruno.- El Morro.- German Busch.- Ines. === COUNTY: Soniquera.- Soniquera. - -San Agustin.- San Cristobal. - Rio Grande.- Soniquera.- San Agustin.- San Agustin.- San Agustin ====PROVINCES: -Nor Lipez.
