Dec. 31, 2012
CONCENTRATIONS OF CREDIT RISK [Text Block]	22. CONCENTRATIONS OF CREDIT RISK Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of temporary cash investments, marketable securities, accounts receivable, and derivatives. The Company places its cash and marketable securities with high quality financial institutions and limits its credit exposure with any one financial institution. At times, the Company’s bank account balances may exceed federally insured limits. As of December 31, 2012 and 2011, 0% and 95%, respectively, of the Company’s total accounts receivable were from one customer to whom 100% of the Company’s copper production is sold. The Company neither deposited nor holds any collateral related to its derivative financial instruments. In addition, to date, the Company has not required any of its counterparties or customers to post collateral.

The entire disclosure for any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact. This disclosure informs financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date.
