The Mina Isidora mine is currently operating. All ore is processed through the La Camorra mill, about 70 miles south of Mina Isidora, which is located on Hecla’s Block B concession. Hecla, the largest gold miner in Venezuela, has been operating successfully since 1999. In 2007, the La Camorra Unit produced 87,490 ounces of gold at an average total cash cost of $537 per ounce.

Information with respect to the La Camorra unit’s production and average costs per ounce of gold produced is set forth in the table below.

(1) During 2007, 2006 and 2005, 16,582, 23,802 and 17,252 tons milled, respectively, and 4,114, 5,407 and 4,602 gold ounces produced were generated from our custom milling business and purchases from third parties, of ore and sands not mined at the La Camorra unit.

(2) Cash costs per ounce of gold represent measurements that are not in accordance with GAAP that management uses to monitor and evaluate the performance of our mining operations. We believe cash costs per ounce of gold provide an indicator of profitability and efficiency at each location and on a consolidated basis, as well as providing a meaningful basis to compare our results to those of other mining companies and other mining operating properties.
