Debt Disclosure [Text Block] | Note 6: Credit Facilities and Capital Leases Credit Facilities We have a $150 million senior secured revolving credit facility, which is collateralized by the shares of common stock held in our material subsidiaries and by our joint venture interests in the Greens Creek mine, all of our rights and interests in the joint venture agreement, and all of our rights and interests in the assets of the joint venture. This credit facility originated with a $60 million senior secured revolving credit agreement entered into in October 2009 that has been amended several times to its current form. Amounts borrowed under the credit agreement are available for general corporate purposes. The interest rate on outstanding loans under the agreement is between 3.00% and 3.75% above the LIBOR or an alternative base rate plus an applicable margin of between 2.00% and 2.75%. We are required to pay a standby fee of between 0.825% and 1.05% per annum on undrawn amounts under the revolving credit agreement. The credit facility is effective until August 1, 2015. In 2012, we incurred $0.5 million in interest expense for the amortization of loan origination fees and $1.0 million in interest expense for commitment fees relating to the credit agreement. The credit agreement includes various covenants and other limitations related to our various financial ratios and indebtedness and investments, as well as other information and reporting requirements, including the following limitations:
| • | Leverage ratio (calculated as total debt divided by EBITDA) of not more than 3.0:1.
| • | Interest coverage ratio (calculated as EBITDA divided by interest expense) of not less than 3.0:1.
| • | Current ratio (calculated as current assets divided by current liabilities) of not less than 1.10:1.
| • | Tangible net worth of greater than $500 million.
We were in compliance with all covenants under the credit agreement as of December 31, 2012. We have not drawn funds on the current revolving credit facility as of the filing date of this Form 10-K. Capital Leases Since 2009, we have entered into various lease agreements for equipment at our Greens Creek and Lucky Friday units, which we have determined to be capital leases. At December 31, 2012, the total liability balance associated with capital leases, including purchase option amounts, was $17.5 million, with $5.6 million of the liability classified as current and $11.9 million classified as non-current. At December 31, 2011, the total liability balance associated with capital leases was $10.3 million, with $4.0 million of the liability classified as current and $6.3 million classified as non-current.
