	1	Organization and Liquidity:

	Petro River Oil Corp (the “Company”) is an enterprise engaged in the exploration and exploitation of heavy oil properties. The Company’s principal administrative office is located in Houston, Texas and its principal operations are in Kansas and Western Missouri.

	Petro River Oil LLC (“Petro”) was incorporated under the laws of the State of Delaware on March 3, 2011. Through proceeds received from the issuance of various promissory notes, on February 1, 2012, Petro purchased various interests in oil and gas leases, wells, records, data and related personal property located along the Mississippi Lime play in the state of Kansas from Metro Energy Corporation (“Metro”), a Louisiana company, and other interrelated entities, which were in financial distress. These assets were purchased by Petro from Metro through a court approved order as Metro was undergoing Chapter 11 Bankruptcy proceedings as a Debtor-In-Possession of these various oil and gas assets. Petro purchased these assets for cash consideration of $2,000,000 as well as a 25% non-managing membership interest in the Company. Subsequent to the Metro purchase the Company engaged Energy Source Advisors to renew a number of the leases acquired in the Metro purchase and to lease additional acreage. As a result of the asset purchase from Metro and the completion of the additional lease renewals and additional acreage purchases, the Company obtained a total of 115,000 gross/85,000 net acres of leases, having unproven reserves at the time of acquisition, in the Mississippi Lime in Southeast Kansas for total cost of $12.2 million.

	On April 23, 2013, the Company executed and consummated a securities purchase agreement (the “Securities Purchase Agreement”) by and among the Company, Petro, and the investors in Petro (the “Investors,”), namely, the holders of outstanding secured promissory notes of Petro (the “Notes”), and the members of Petro holding membership interests in Petro (the “Membership Interests”, and, together with the Notes, the “Acquired Securities”) sold by the Company (the “Share Exchange”).

	In the Share Exchange, the Investors exchanged their Acquired Securities for 591,021,011 newly issued shares of common stock of the Company (“Common Stock”). As a result, upon completion of the Share Exchange, Petro became the Company’s wholly-owned subsidiary.

	As a result of the Share Exchange, the Company acquired 100% of the member units of Petro and consequently, control of the business and operations of Petro. Under generally accepted accounting principles in the United States, (“U.S. GAAP”) because Petro’s former members and note holders held 80% of the issued and outstanding shares of the Company as a result of the Share Exchange, Petro is deemed the accounting acquirer while the Company remains the legal acquirer. Petro adopted the fiscal year of the Company. Prior to the Share Exchange, all historical financial statements presented are those of Petro. The equity of the Company is the historical equity of Petro, retrospectively restated to reflect the number of shares issued by the Company in the transaction.

	Liquidity and Management Plans

	The Company is focused on developing its recently acquired Mississippi Lime acreage. Over the last 12 months the Company has continued to build out its leadership and technical team. Additionally, the Company has been in discussions with industry partners to capitalize and develop acreage in the Mississippi Lime. The Company continues to seek out joint venture partners and acquisition targets.

	Projects related to our legacy heavy oil reservoirs are still in technical review but a determination has been made to continue to testing pilot technologies and processes on the Missouri heavy oil assets. In Missouri, we are continuing to analyze reservoir data and testing results. The data is being utilized in the understanding and test phases to develop an economic heavy oil production reserve base.

	Projects related to the heavy oil reservoirs are in technical review. The Company has an extensive amount of technical and reservoir information on both Missouri and Kansas positions. The data is being utilized in the understanding and test phases to develop an economic heavy oil production reserve base.

	The ultimate goal of the management of the Company is to maximize shareholder value. Specific targets include: increasing production by developing its acreage, increasing profitability margins by evaluating and optimizing its production, and executing its business plan to increase property values, prove its reserves, and expand its asset base.

	At April 30, 2014, the Company had working capital of approximately $7.5 million and has incurred losses since it commenced operations and utilized cash in its operating activities to date. In addition, Petro has a limited operating history. At April 30, 2014, the Company had cash and cash equivalents of approximately $8.4 million. Management believes that the current level of working capital is sufficient to maintain current operations in Kansas and Missouri as well as the planned added operations for the next 12 months. Management intends to continue to raise capital through debt and equity instruments in order to achieve its business plans. Management can provide no assurances that the Company will be successful in capital raising efforts.

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies:

(a)

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include volumes of oil and natural gas reserves, abandonment obligations, impairment of oil and natural gas properties, depreciation and accretion, income taxes, fair value of financial instruments, and contingencies.

Oil and gas proven reserve estimates, which are the basis for unit-of-production depletion and the full cost ceiling test, have a number of inherent uncertainties. The accuracy of any reserve estimate is a function of the quality of available data and of engineering and geological interpretation and judgment. Results of drilling, testing, and production subsequent to the date of the estimate may justify revision of such estimate. Accordingly, reserve estimates are often different from the quantities of oil and gas that are ultimately recovered. In addition, reserve estimates are vulnerable to changes in prices of crude oil and gas. Such prices have been volatile in the past and can be expected to be volatile in the future. As of April 30, 2014 and 2013, the Company had no estimated proven reserves.

(b)

Cash and Cash Equivalents:

Cash and cash equivalents include all highly liquid monetary instruments with original maturities of three months or less when purchased to be cash equivalents. These investments are carried at cost, which approximates fair value. Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash deposits. The Company maintains its cash in institutions insured by the Federal Deposit Insurance Corporation (“FDIC”). At times, the Company’s cash and cash equivalent balances may be uninsured or in amounts that exceed the FDIC insurance limits.

(c)

Oil and Gas Operations:

Oil and Gas Properties: The Company uses the full-cost method of accounting for its exploration and development activities. Under this method of accounting, the costs of both successful and unsuccessful exploration and development activities are capitalized as oil and gas property and equipment. Proceeds from the sale or disposition of oil and gas properties are accounted for as a reduction to capitalized costs unless the gain or loss would significantly alter the relationship between capitalized costs and proved reserves of oil and natural gas attributable to a country, in which case a gain or loss would be recognized in the statement of operations. All of the Company’s oil and gas properties are located within the continental United States, its sole cost center.

Oil and gas properties may include costs that are excluded from costs being depleted. Oil and gas costs excluded represent investments in unproved properties and major development projects in which the Company owns a direct interest. These unproved property costs include non-producing leasehold, geological and geophysical costs associated with leasehold or drilling interests and in process exploration drilling costs. All costs excluded are reviewed at least annually to determine if impairment has occurred.

The Company accounts for its unproven long-lived assets in accordance with Accounting Standards Codification (“ASC”) Topic 360-10-05, “Accounting for the Impairment or Disposal of Long-Lived Assets.” ASC Topic 360-10-05 requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the historical cost carrying value of an asset may no longer be appropriate. The Company performed a comparable study of unproven long-lived assets as of April 30, 2013 and determined that none of its long-term assets at April 30, 2013 were impaired. As of April 30, 2014, management performed a third party study of the oil and gas assets. Management concluded that the Montana assets was impaired by $75,000 and the Kansas assets were impaired by $4,638,973. The Company recorded a $4,713,973 impairment to the statement of operations during the year ended April 30, 2014.

Proved Oil and Gas Reserves: In accordance with Rule 4-10 of SEC Regulation S-X, proved oil and gas reserves are the estimated quantities of crude oil, natural gas and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. All the oil and gas properties with proven reserves were impaired to the salvage value prior to the merger. The price used to establish economic producibility is the average price during the 12-month period preceding the end of the entity’s fiscal year and calculated as the un-weighted arithmetic average of the first-day-of-the-month price for each month within such 12-month period.

Depletion, Depreciation and Amortization: Depletion, depreciation and amortization is provided using the unit-of-production method based upon estimates of proved oil and gas reserves with oil and gas production being converted to a common unit of measure based upon their relative energy content. For the year ended April 30, 2014, the four month period ended April 30, 2013 and the period February 2, 2012 (commencement of operations) to December 31, 2012, all oil and gas reserves were classified as unproven. Investments in unproved properties and major development projects are not amortized until proved reserves associated with the projects can be determined or until impairment occurs. If the results of an assessment indicate that the properties are impaired, the amount of the impairment is deducted from the capitalized costs to be amortized. Once the assessment of unproved properties is complete and when major development projects are evaluated, the costs previously excluded from amortization are transferred to the full cost pool and amortization begins. The amortizable base includes estimated future development costs and, where significant, dismantlement, restoration and abandonment costs, net of estimated salvage value.

In arriving at rates under the unit-of-production method, the quantities of recoverable oil and natural gas reserves are established based on estimates made by the Company’s geologists and engineers which require significant judgment, as does the projection of future production volumes and levels of future costs, including future development costs. In addition, considerable judgment is necessary in determining when unproved properties become impaired and in determining the existence of proved reserves once a well has been drilled. All of these judgments may have significant impact on the calculation of depletion expenses. There have been no material changes in the methodology used by the Company in calculating depletion, depreciation and amortization of oil and gas properties under the full cost method during the year ended April 30, 2014, the four month period ended April 30, 2013 and the period February 2, 2012 (commencement of operations) to December 31, 2012.

(d)

Asset Retirement Obligations:

The Company recognizes a liability for the estimated fair value of site restoration and abandonment costs when the obligations are legally incurred and the fair value can be reasonably estimated. The fair value of the obligations is based on the estimated cash flow required to settle the obligations discounted using the Company’s credit adjusted risk-free interest rate. The obligation is recorded as a liability with a corresponding increase in the carrying amount of the oil and gas assets. The capitalized amount will be depleted on a unit-of-production method. The liability is increased each period, or accretes, due to the passage of time and a corresponding amount is recorded in the statement of operations.

Revisions to the estimated fair value would result in an adjustment to the liability and the capitalized amount in oil and gas assets.

(e)

Oil and Gas Revenue:

Sales of oil and gas, net of any royalties, are recognized when oil has been delivered to a custody transfer point, persuasive evidence of a sales arrangement exists, the rights and responsibility of ownership pass to the purchaser upon delivery, collection of revenue from the sale is reasonably assured, and the sales price is fixed or determinable. The Company sells oil and gas on a monthly basis. Virtually all of its contracts’ pricing provisions are tied to a market index, with certain adjustments based on, among other factors, whether a well delivers to a gathering or transmission line, the quality of the oil and gas, and prevailing supply and demand conditions, so that the price of the oil and gas fluctuates to remain competitive with other available oil supplies.

(f)

Stock-Based Compensation:

Generally, all forms of stock-based compensation, including stock option grants, warrants, and restricted stock grants are measured at their fair value utilizing an option pricing model on the award’s grant date, based on the estimated number of awards that are ultimately expected to vest. Share-based compensation awards issued to non-employees for services rendered are recorded at either the fair value of the services rendered or the fair value of the share-based payment, whichever is more readily determinable. The expenses resulting from stock-based compensation are recorded as general and administrative expenses in the consolidated statement of operations, depending on the nature of the services provided.

(g)

Income Taxes:

Prior to the Share Exchange, Petro was not subject to income taxes in any jurisdiction. The members of Petro were responsible for the tax liability, if any, related to Petro’s taxable income. Accordingly, no provision for income taxes was reflected in the accompanying consolidated financial statements. The Petro members have concluded that Petro was a pass-through entity and there were no uncertain tax positions that would require recognition in the consolidated financial statements. If Petro were to incur an income tax liability in the future, interest on any income tax liability would be reported as interest expense and penalties on any income tax liability would be reported as income taxes. For the year ended April 30, 2014, the four month period ended April 30, 2013 and the period February 2, 2012 (commencement of operations) to December 31, 2012, no interest and penalties were required to be recorded. The Members’ conclusions regarding uncertain tax positions may be subject to review and adjustment at a later date based upon ongoing analyses of tax laws, regulations and interpretations thereof as well as other factors. At the time of the share exchange, all undistributed losses were closed to additional paid in capital.

Subsequent to the Share Exchange, the Company applies the elements of ASC 740-10 “Income Taxes — Overall” regarding accounting for uncertainty in income taxes. This clarifies the accounting for uncertainty in income taxes recognized in consolidated financial statements and requires the impact of a tax position to be recognized in the consolidated financial statements if that position is more likely than not of being sustained by the taxing authority. As of April 30, 2014 and 2013, the Company did not have any unrecognized tax benefits. The Company does not expect that the amount of unrecognized tax benefits will significantly increase or decrease within the next twelve months. The Company’s federal and state income tax returns are subject to examination by tax authorities beginning with the tax year ended April 30, 2009.

The Company operates in Kansas, Texas and Missouri. The Company accounts for any tax penalties and interest as general and administrative expenses.

Deferred taxes are computed based on the tax liability or benefit in future years of the reversal of temporary differences in the recognition of income or deduction of expenses between financial and tax reporting purposes. The net difference, if any, between the provision for taxes and taxes currently payable is reflected in the balance sheet as deferred taxes. Deferred tax assets and/or liabilities, if any, are classified as current and non-current based on the classification of the related asset or liability for financial reporting purposes, or based on the expected reversal date for deferred taxes that are not related to an asset or liability. Valuation allowances are recorded to reduce deferred tax assets to that amount which is more likely than not to be realized.

Per Share Amounts:

Basic net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net earnings (loss) per common share is determined using the weighted-average number of common shares outstanding during the period, adjusted for the dilutive effect of common stock equivalents. In periods when losses are reported, which is the case for the year ended April 30, 2014, the four month period ended April 30, 2013, and the period February 2, 2012 (commencement of operations) to December 31, 2012 presented in these consolidated financial statements, the weighted-average number of common shares outstanding excludes common stock equivalents because their inclusion would be anti-dilutive.

The Company had the following common stock equivalents at April 30, 2014, April 30, 2013 and December 31, 2012:

Fair Value of Financial Instruments:

All financial instruments, including cash and cash equivalents, accounts receivable, prepaid expenses and accounts payable and accrued expenses are to be recognized on the consolidated balance sheet initially at carrying value. The carrying value of these assets approximates their fair value due to their short-term maturities.

At each balance sheet date, the Company assesses financial assets for impairment with any impairment recorded in the consolidated statement of operations. To assess loans and receivables for impairment, the Company evaluates the probability of collection of accounts receivable and records an allowance for doubtful accounts, which reduces loans and receivables to the amount management reasonably believes will be collected. In determining the amount of the allowance, the following factors are considered: the length of the time the receivable has been outstanding, specific knowledge of each customer’s financial condition and historical experience.

Market risk is the risk that changes in commodity prices will affect the Company’s oil sales, cash flows or the value of its financial instruments. The objective of commodity price risk management is to manage and control market risk exposures within acceptable limits while maximizing returns.

The Company is exposed to changes in oil prices which impact its revenues and to changes in natural gas process which impact its operating expenses.

The Company does not utilize financial derivatives or other contracts to manage commodity price risks.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price).

Fair value measurements are categorized using a valuation hierarchy for disclosure of the inputs used to measure fair value, which prioritize the inputs into three broad levels:

Level 1 - Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 - Pricing inputs are other than quoted prices in active markets included in level 1, which are either directly or indirectly observable as of the reported date, and include those financial instruments that are valued using models or other valuation methodologies.

Level 3 - Pricing inputs include significant inputs that are generally less observable from objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value.

Subsequent Events:

The Company evaluates subsequent events through the date when the consolidated financial statements are issued.

Recent Accounting Pronouncements:

In July 2013, the FASB issued ASU 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” Under this new guidance, companies must present this unrecognized tax benefit in the financial statements as a reduction to deferred tax assets created by net operating losses or other tax credits from prior periods that occur in the same taxing jurisdiction. If the unrecognized tax benefit exceeds such credits it should be presented in the financial statements as a liability. This update is effective for annual and interim reporting periods for fiscal years beginning after December 15, 2013. The Company is currently evaluating the effects of ASU 2013-11 on the consolidated financial statements.

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers. Amendments in this ASU create Topic 606, Revenue from Contracts with Customers, and supersede the revenue recognition requirements in Topic 605, Revenue Recognition, including most industry-specific revenue recognition guidance throughout the Industry Topics of the Codification. In addition, the amendments supersede the cost guidance in Subtopic 605-35, Revenue Recognition—Construction-Type and Production-Type Contracts, and create new Subtopic 340-40, Other Assets and Deferred Costs—Contracts with Customers. In summary, the core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU is the final version of Proposed Accounting Standards Update 2011-230—Revenue Recognition (Topic 605) and Proposed Accounting Standards Update 2011–250—Revenue Recognition (Topic 605): Codification Amendments, both of which have been deleted. The amendments in this ASU are effective for the Company for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. The Company is currently evaluating the effects of ASU 2014-09 on the consolidated financial statements.

In June 2014, the FASB issued ASU 2014-12, Compensation- Stock Compensation. The amendments in this update apply to reporting entities that grant their employees share-based payments in which the terms of the award provide that a performance target can be achieved after the requisite service period. This ASU is the final version of Proposed Accounting Standards Update EITF-13D—Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period, which has been deleted. The proposed amendments would apply to reporting entities that grant their employees share-based payments in which the terms of the award provide that a performance target could be achieved after the requisite service period. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015, and early adoption is permitted. The Company is currently evaluating the effects of ASU 2014-12 on the consolidated financial statements.

Management does not believe that any recently issued, but not yet effective accounting pronouncements, if adopted, would have a material effect on the accompanying consolidated financial statements.

	The Company performed a test of oil and gas assets as of April 30, 2013, and concluded that the excess purchase price paid for its Missouri property exceeded it net realizable value, and as a result it recognized an impairment in the amount of $1,093,527.

	As of April 30, 2014, management performed an impairment test of the oil and gas assets. All Montana leases expired during the year ended April 30, 2014, and as a result, management fully impaired the Montana assets by $75,000. In addition, management engaged an independent third party to test the Kansas assets for impairment. Management was not aware of any impairment indicators, but the third party specialist concluded that the Kansas assets were impaired by $4,638,973, specifically as a result of expiring leases and comparable acreage values. The Company recorded a $4,713,973 impairment to the statement of operations during the year ended April 30, 2014.

	Missouri

	At April 30, 2014, the Company’s Missouri lease holdings totaled 1,272 gross acres with 98.4% working interest.

	On separate pilot projects at Deerfield, the Company built two 500 barrel of oil per day steam drive production facilities (Marmaton River and Grassy Creek) comprised of 116 production wells, 39 steam injection wells and 14 service and observation wells. Throughout the Deerfield area, the Company has drilled 73 exploration/delineation wells with a 67% success rate.

	As of April 30, 2014 and 2013, all Missouri assets were carried at salvage value, since the Company’s current business plans do not contemplate raising the necessary capital to develop these properties. The Company is in current discussions with third parties to use the acreage as a testing site for heavy oil solutions with contemplated profit sharing opportunities.

	Kentucky

	As a result of the share exchange, the Company acquired Kentucky lease holdings which include a 37.5% working interest in 27,150 unproved gross acres (10,181 net acres). At April 30, 2014 the Kentucky lease holdings acquired as a result of the share exchange have expired.

	Montana

	As of April 30, 2014, the Montana leasehold in the Devils Basin prospect have expired.

	As April 30, 2013, the assets were carried at salvage value. During the year ended April 30, 2014, management fully impaired the asset to zero due to the expiration of the leases.

	Kansas

	Through proceeds received from the issuance of various promissory notes, on February 1, 2012 Petro purchased various interests in oil and gas leases, wells, records, data and related personal property located along the Mississippi Lime play in the state of Kansas from Metro Energy Corporation (“Metro”), a Louisiana company and other interrelated entities, which were in financial distress. These assets were purchased by Petro from Metro through a court approved order as Metro was undergoing Chapter 11 Bankruptcy proceedings as a Debtor-In-Possession of these various oil and gas assets. Petro purchased these assets for cash considerations of $2,000,000 as well as a 25% non-managing membership interest in the Company. Subsequent to the Metro purchase the Company engaged Energy Source Advisors to renew a number of the leases acquired in the Metro purchase and to lease additional acreage. As a result of the asset purchase from Metro and the completion of the additional lease renewals and additional acreage purchases, the Company obtained a total of 115,000 gross/85,000 net acres of leases, having unproven reserves at the time of acquisition, in the Mississippi Lime play in Southeast Kansas for total cost of $12.2 million. The Company also acquired over 60 square miles of proprietary 3D seismic data over prospective Mississippi Lime acreage in the same area. During the year ended April 30, 2014, the period January 1, 2013 to April 30, 2013 and for the period February 2, 2012 (commencement of operations) to December 31, 2012, the Company capitalized approximately $327,002, $98,764 and $12,191,965 of Kansas oil and gas expenditures. As of April 30, 2014, management engaged an independent third party to test the Kansas assets for impairment. Throughout the year, management was not aware of any impairment indicators, but during the annual impairment test, the third party specialist concluded that the Kansas assets were impaired by $4,638,973, principally due to comparable acreage values.

	Other

	Other property consists primarily of four used steam generators and related equipment that will be assigned to future projects. As of April 30, 2014, management concluded that impairment was not necessary as all other assets were carried at salvage value.

	12	Income Taxes:

	As of April 30, 2014 and April 30, 2013, the Company had approximately $6.4 million and $3.5 million of net operating loss carryovers (“NOLs”) which expire beginning in 2027. The U.S. net operating loss carryovers are subject to limitation under Internal Revenue Code Section 382 should there be a greater than 50% ownership change as determined under the regulations. Management has determined that a change in ownership occurred as a result of the share exchange on April 23, 2013. Therefore, the net operating loss carryovers are subject to an annual limitation of approximately $156,000.

	The income tax expense (benefit) consists of the following:

		For the year ended			For the period			For the period
		30-Apr-14			January 1, 2013 to			February 2, 2012 (Commencement

	In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. Based on this assessment management has established a full valuation allowance against all of the deferred tax assets for every period, since it is more likely than not that all of the deferred tax assets will not be realized.

	The Company’s deferred tax assets (liabilities) consisted of the effects of temporary differences attributable to the following:

		30-Apr-14			30-Apr-13			31-Dec-12

	U.S. Net operating loss carryovers	$	2,473,922		$	1,203,780		$	-

Commitments and Contingencies Disclosure [Abstract]	'
Contingency and Contractual Obligations	'
	13	Contingency and Contractual Obligations:

	As a result of the Share Exchange, the Company inherited the following contingencies:

	(a) In January 2010, the Company experienced a flood in its Calgary office premises as a result of a broken water pipe. There was significant damage to the premises rendering them unusable until remediation was completed by the landlord. Pursuant to the lease contract, the Company asserted that rent should be abated during the remediation process and accordingly, the Company ceased making rent payments in December 2009. During the remediation process, the Company engaged an independent environmental testing company to test for air quality and for the existence of other potentially hazardous conditions. The testing revealed the existence of potentially hazardous mold and the consultant provided specific written instructions for the effective remediation of the premises. During the remediation process, the landlord did not follow the consultant’s instructions to correct the potentially hazardous mold situation, and subsequently in June 2010, gave notice and declared the premises to be ready for occupancy. The Company re-engaged the consultant to re-test the premises and the testing results again revealed the presence of potentially hazardous mold. The Company determined that the premises were not fit for re-occupancy, considered the landlord to be in default of the lease, and considered the lease to be terminated.

	The landlord disputed the Company’s position and gave notice that it considers the Company to be in default of the lease for failure to re-occupy the premises.

	The landlord has previously claimed that the Company owed monthly rent for the premises from January 2010 to June 30, 2010 in the amount of $247,348 and as a result of the alleged default, pursuant to the terms of the lease, the Company owed three months accelerated rent in the amount of $114,837. The landlord previously also asserted that the Company would be liable for an amount up to the full lease obligation of $1,596,329 which otherwise would have been due as follows:

	Year Ended April 30
	2011		$	473,055
	2012			473,055
	2013			473,055
	2014			177,164
	Total		$	1,596,329

	On January 30, 2014, the landlord filed a Statement of Claim with the Court of Queen’s Bench of Alberta against the Company in the approximate amount of $759,000. On March 26, 2014, the Company filed a Statement of Defence in which it challenged the allegations made by the landlord. The Company claims that the two year limitation period as defined under the “Limitations Act”, as established in Alberta, Canada, has been exceeded and therefore the Statement of Claim filed by the landlord should be barred in its entirety.

	(b) On March 15, 2013, a former employee of the Company (VP-Operations) commenced an action in the Court of Queen’s Bench of Alberta claiming wrongful termination and seeking severance in an amount approximating US$185,000. On May 3, 2013, the Company reached a settlement with the former employee and entered into a formal settlement and release of claims agreement. As consideration for full settlement and mutual release, the Company issued the former employee 200,000 shares of common stock of the Company, valued at $0.40 per share or $80,000, and paid $50,000 during the year ended April 30, 2014, respectively.

	(c) In September 2013, the Company was notified by the Railroad Commission of Texas (the “Commission”) that the Company was not in compliance with regulations promulgated by the Commission. The Company was therefore deemed to have lost its corporate privileges within the State of Texas and as a result, all wells within the state would have to be plugged. The Commission therefore collected $25,000 from the Company, which was originally deposited with the Commission, to cover a portion of the estimated costs of $88,960 to plug the wells. In addition to the above, the Commission also reserved its right to separately seek any remedies against the Company resulting from its noncompliance.

	(d) The Company is from time to time involved in legal proceedings in the ordinary course of business. It does not believe that any of these claims and proceedings against it is likely to have, individually or in the aggregate, a material adverse effect on its financial condition or results of operations.
