| Significant Accounting Policies [Abstract] | |
| Basis of presentation | Basis of presentation The consolidated financial statements of the Company have been prepared in accordance with GAAP applicable to exploration stage enterprises, and are expressed in U.S. dollars. The Company's fiscal year end is 30 June. |
| Principles of consolidation | Principles of consolidation These consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary Dynamic Gravel Holdings Ltd. (Dynamic Gravel), a company incorporated in the province of Alberta on 21 November 2007. All significant inter-company balances and transactions have been eliminated upon consolidation. |
| Cash and cash equivalents | Cash and cash equivalents Cash and cash equivalents include highly liquid investments with original maturities of three months or less. |
| Derivative financial instruments | Derivative financial instruments The Company has not, to the date of these consolidated financial statements, entered into derivative instruments to offset the impact of foreign currency fluctuations. |
| Mineral property costs | Mineral property costs The Company is primarily engaged in the acquisition, exploration and development of mineral properties. Mineral property acquisition costs are initially capitalized as tangible assets when purchased. At the end of each fiscal quarter end, the Company assesses the carrying costs for impairment. If proven and probable reserves are established for a property and it has been determined that a mineral property can be economically developed, costs will be amortized using the units-of-production method over the estimated life of the probable reserve. Mineral property exploration costs are expensed as incurred. Estimated future removal and site restoration costs, when determinable are provided over the life of proven reserves on a units-of-production basis. Costs, which include production equipment removal and environmental remediation, are estimated each period by management based on current regulations, actual expenses incurred, and technology and industry standards. Any charge is included in exploration expense or the provision for depletion and depreciation during the period and the actual restoration expenditures are charged to the accumulated provision amounts as incurred.
As of the date of these consolidated financial statements, the Company has not established any proven or probable reserves on its mineral properties and incurred only acquisition and exploration costs (Note 3). Although the Company has taken steps to verify title to mineral properties in which it has an interest, according to the usual industry standards for the stage of exploration of such properties, these procedures do not guarantee the Company's title. Such properties may be subject to prior agreements or transfers and title may be affected by undetected defects. |
| Environmental expenditures | Environmental expenditures The operations of the Company have been, and may in the future, be affected from time to time, in varying degrees, by changes in environmental regulations, including those for future reclamation and site restoration costs. Both the likelihood of new regulations and their overall effect upon the Company vary greatly and are not predictable. The Company's policy is to meet or, if possible, surpass standards set by relevant legislation, by application of technically proven and economically feasible measures. Environmental expenditures that relate to ongoing environmental and reclamation programs are charged against earnings as incurred or capitalized and amortized depending on their future economic benefits. Estimated future reclamation and site restoration costs, when the ultimate liability is reasonably determinable, are charged against earnings over the estimated remaining life of the related business operation, net of expected recoveries. |
| Income taxes | Income taxes Deferred income taxes are reported for timing differences between items of income or expense reported in the consolidated financial statements and those reported for income tax purposes in accordance with ASC 740, Income Taxes |
| Comprehensive loss | Comprehensive loss ASC 220, Comprehensive Income |
| Basic and diluted net loss per share | Basic and diluted net loss per share The Company computes net income (loss) per share in accordance with ASC 260, Earnings per Share |
| Segments of an enterprise and related information | Segments of an enterprise and related information ASC 280, Segment Reporting |
| Start-up expenses | Start-up expenses The Company has adopted ASC 720-15, Start-Up Costs |
| Foreign currency translation | Foreign currency translation The Company's functional and reporting currency is U.S. dollars. The consolidated financial statements of the Company are translated to U.S. dollars in accordance with ASC 830, Foreign Currency Matters |
| Use of estimates and assumptions | Use of estimates and assumptions The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenditures during the reporting period. Actual results could differ from these estimates. |
| Comparative figures | Comparative figures Certain comparative figures have been adjusted to conform to the current year's presentation. |
| Recent adopted accounting pronouncements | Recent adopted accounting pronouncements In April 2014, ASC guidance was issued related to Discontinued Operations which changed the criteria for determining which disposals can be presented as discontinued operations and modified related disclosure requirements. The updated guidance requires an entity to only classify discontinued operations due to a major strategic shift or a major effect on an entity's operations in the financial statements. The updated guidance will also require additional disclosures relating to discontinued operations. Adoption of the new guidance had no impact on the consolidated financial position, results of operations or cash flows. In July 2013, ASC guidance was issued related to the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss or a tax credit carryforwards exists. The updated guidance requires an entity to net its unrecognized tax benefits against its jurisdictional deferred tax assets related to net operating loss carryforward, a similar tax loss, or tax credit carryforwards. A gross presentation will be required only if such carryforwards are not available or would not be used by the entity to settle any additional income taxes resulting from disallowance of the uncertain tax position. Adoption of the new guidance, effective for the fiscal year beginning 1 July 2014, had no impact on the consolidated financial position, results of operations or cash flows. In March 2013, ASC guidance was issued related to foreign currency matters to clarify the treatment of cumulative translation adjustments when a parent sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity. The updated guidance also resolves the diversity in practice for the treatment of business combinations achieved in stages in a foreign entity. Adoption of the new guidance, effective for the fiscal year beginning 1 July 2014, had no impact on the consolidated financial position, results of operations or cash flows. |
| Recently issued accounting pronouncements | Recently issued accounting pronouncements In June 2014, Accounting Standards Update (ASU) guidance was issued to resolve the diversity of practice relating to the accounting for stock based performance awards that the performance target could be achieved after the employee completes the required service period. The update is effective prospectively or retrospectively beginning 1 July 2015. The Company does not expect the updated guidance to have an impact on the consolidated financial position, results of operations or cash flows. In May 2014, ASU guidance was issued related to revenue from contracts with customers. The new standard provides a five-step approach to be applied to all contracts with customers and also requires expanded disclosures about revenue recognition. The ASU is effective for annual reporting periods beginning after 15 December 2016, including interim periods and is to be retrospectively applied. Early adoption is not permitted. The Company is currently evaluating this guidance and the impact it will have on its Consolidated Financial Statements. |
