The Registrant's management has been working to finalize the accounting adjustments resulting from the initial transition from International Financial Reporting Standards to U.S. Generally Accepted Accounting Principles. As a result, the Registrant is unable to file its Annual Report on Form 10-K within the prescribed time period without unreasonable effort or expense. The Registrant expects to file within the extension period.

If answer is no, identify report(s).

[ x ] Yes [ ] No

(3)

Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof ?

[ x ] Yes [ ] No

If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

Previously, the Registrant’s financial statements were prepared in accordance with International Financial Reporting Standards (“IFRS”) issued by the International Accounting Standards Board, as permitted by securities regulators in Canada, as well as in the United States under the status of a “foreign private issuer” as defined under Rule 3b-4 under the Securities Exchange Act of 1934, as amended. At the end of the second quarter of 2016, the Registrant determined that it no longer qualified as a “foreign private issuer” under the Securities and Exchange Commission rules. Consequently, the Registrant is now required to prepare its consolidated financial statements in accordance with United States generally accepted accounting principles ("US GAAP"), which requires retrospective application since the Registrant’s inception. Due to differences in accounting treatments between IFRS and US GAAP, certain amounts historically reported for the Registrant's financial position, operating results, and cash flows under IFRS will change under US GAAP standards and; therefore, will be incomparable to amounts previously reported under IFRS, for all previous periods.

During the preparation of its financial statements, the Registrant has determined that, among other things, differences exist in US GAAP and IFRS standards with respect to the following items and topics: 1) capitalization of costs for long-lived assets, 2) recognition of derivative financial instruments and related effects, 3) measurement of asset retirement obligations, 4) recognition of depreciation and depletion through cost of sales, 5) and income taxes. Additionally, the presentation and disclosure requirements for balances and transactions differs under IFRS and US GAAP.

Due to the fact that the Registrant has not yet finalized its review of the financial statements, the Registrant is not able to provide a reasonable estimate of the results.
