Mining Claims
Other Commitments, Description	A portion of the Company’s mining claims on the Company’s properties are subject to lease and option agreements with various terms, obligations, and royalties payable in certain circumstances.
Claim Maintenance Fees
Other Commitments, Description	The Company pays federal and county claim maintenance fees on unpatented claims that are included in the Company’s mineral exploration properties. Should the Company continue to explore all of the Company’s mineral properties, it expects annual fees to total approximately $202,950 per year in the future, of which $97,587 is for claims maintenance fees for LM LLC. These will be remitted by the Company, due to PM&G’s failure to meet the required minimum work commitment on that property and the resulting future dissolution of LM LLC into the Company (See Note 3).
