February 19, 2013. Thompson Falls, Montana. United States Antimony Corporation (“USAC”, NYSE MKT “UAMY”) announced initial mill feed assays from its Los Juarez silver-antimony-gold property. The assays were 0.728 % antimony, 6.22 ounces of silver (193 grams) per metric ton, and 0.023 ounces of gold (0.7 grams) per metric ton and represent 1,415 tons of dump rock mixed with soil from the Minas Grande open pit that was 30 meters deep. There is no assurance that these values will continue in other areas of the property
The disseminated Los Juarez mineralization is in vertical jasperoid zones mapped for 2.18 miles (3.5 kilometers) along strike and over a width of 0.5 miles (0.8 kilometers). The deposit is open in all directions.
USAC’s Chief Executive Officer, John Lawrence, commented that these values are exceptional for an open-pit, bulk-mineable deposit where mining costs are less than $10.00 per metric ton.
USAC is a diversified producer of antimony, precious metals, and zeolite with operations in the Unites States and Mexico.
It means that each ton in that sample would generate revenue above $300. Deduct mining costs of $10/t and separation costs of x and multiply by processing capacity and u can get an idea about gross revenue and gross profit if these grades are widespread over the deposit.
The surface area of the deposit is 3,500 meters X 800 meters. One issue is the depth of the deposit. But this press release talks about mining 30 meters deep. My understanding is that 1 cubic meter = If these values hold throughout the entire deposit
"6.22 ounces of silver (193 grams) per metric ton."
How good is this?
It's better than Revett's [1 ounce per ton]
It's better than Silver Crest's [1.3 ounces per ton]
It's better than Coeur d'Alene's [2.9 ounces per ton]
It's better than First Majestic's [in Q2 2011 it reported 3.7 ounces per ton]
It's better than Fortuna's [4.7 ounce per ton]
It's better than Pan American's [4.7 ounces per ton]
It's better than Silver Standard's [5.5 ounces per ton]
It's almost as good as Silver Corp's [6.8 ounces per ton]
Better than this assay is Hecla, whose ore in 2011 was 8.8 ounces per ton
Better than this assay is U.S. Silver's, whose ore was 9 ounces per ton.
