Maybe you are thinking of this:

Assuming an antimony price of $2.25/lb and a gold price at $700/ounce, and process recovery rates of 85% for antimony and 90% for gold, a seasonally operated 125 tpd concentrating plant could ship stibnite concentrates during a five year period and make a profit of about $27 million over the life of the operation. The mine would pay back capital costs in the third or fourth quarter of the third year of development. Antimony, which accounts for 77 percent of the value of the product under the mining scenario, would clearly drive the project although gold (23 percent of total value) is a significant byproduct. Gold bars would be produced at the mine site thus creating early cash flow. Maintaining stibnite (ore of antimony) concentrate quality for overseas markets is very important to the success of the proposed development. Preliminary metallurgical testing of a bulk sample from the Workman’s Bench Lode shows high recovery rates of gold and antimony. Other impacting factors include wall rock stability underground permitting issues, and metal price trends of both antimony and gold

Man, have prices changed since Jan 5-2009 when TB said this....
