The Company has developed proprietary technology to smelt a variety of raw materials and remove impurities such as lead, arsenic, bismuth, mercury, selenium, silver, and gold. MEXICAN ANTIMONY DEPOSITS Most of the Mexican antimony deposits are oxide ores or mixed oxide sulfide deposits. The oxides, primarily the mineral senarmontite, are recoverable by gravimetric methods, typically jigs and tables. The sulfide ores, typically the mineral stibnite, are recoverable by flotation. During World War II, the United States had relied on Mexico for antimony. Historically, Mexico was at one point the second largest producer of antimony in the world. RS – NOVEMBER, 2012 4

INVENTORY USAC has accumulated large inventories of raw materials at Madero, Puerto Blanco, and the Los Juarez property and is now planning to process and sell as much inventory as possible before the end of 2012. STRATEGIC METAL Antimony is considered a “strategic metal” and wartime applications include antimony oxide used as a flame retardant in plastics and textiles for vehicles and aircraft, antimony metal used in storage batteries and in ordnance to harden lead.

MINING LOS JUAREZ PROPERTY, QUERETARO, MEXICO At the Los Juarez property in Queretaro, Mexico, USAC relied on a Mexican Government publication, Consejo de Recursos Minerales, Monografia Geologico-Minera del Estado de Querearo, pages 74 -75. The paper reported a reserve of 1, 000 metric tons containing 253 grams per ton silver and 1. 8% antimony. The deposit was interpreted as a manto (layered) deposit up to 5 meters thick. Although USAC used Los Juarez mine face, "Minas Grande West“, the report to start mining, it was disallowed by is one of five faces, Los Juarez, Queretaro, Mexico. the S. E. C. as a basis for reserves. Preliminary progress includes surface mapping, analytic procedures, property acquisition, permitting, mining procedures, trucking negotiations, mill preparations, mill feed grade determinations, mill recovery, and smelting considerations. Detailed mapping and sampling delineated jasperoid mineralization over an east-west strike length of 3. 5 kilometers with a maximum width of 1 kilometer. In all cases, the silver and gold mineralization is associated with antimony. Preliminary exploration indicates that this could be a deep-seated jasperoid. RS – NOVEMBER, 2012 8

Drilling and blasting is establishing faces in the jasperoids. Truckload samples have assayed approximately 2% antimony, 8 ounces of silver and 0. 015 ounces of gold per ton. Presently, the Company has more than 8, 000 tons of mill feed from Los Juarez. New paved road to Los Juarez, partially completed entire distance. The antimony, silver, and gold are recoverable by flotation methods. The concentrate grade will be improved by depressing carbonaceous material in the feed. RS – NOVEMBER, 2012 9

Preliminary smelting has indicated good recovery and an excellent product grade. An initial mill trial of 250 tons of dump rock from Los Juarez has been completed. The dump rock was badly diluted with soil from the mine and mud from the mill yard. The results were as follows: Item Range of head assays Range of tail assays Range of concentrate assays Average grade of concentrates RS – NOVEMBER, 2012 Antimony 0. 47 -1. 12% 0. 14 -0. 51% 32. 5 -44. 4% 38. 6% Silver Gold 3. 26 -6. 38 ounces 0. 006 -0. 057 ounces per metric ton 0. 47 -3. 33 ounces 0. 018 -0. 077 ounces per metric ton 270. 8 -306. 86 0. 46 -0. 6 ounces per metric ton 288. 9 ounces 0. 548 ounces per metric ton 10

MILLING PUERTO BLANCO MILL, GUANAJUATO, MEXICO The crushing circuit is run one shift to operate the mill for three shifts. It also includes a large pre-crusher for oversize rock from the Los Juarez deposit. Currently, the combination flotation-gravity mill has a capacity of 150 metric tpd. RS – NOVEMBER, 2012 11

Puerto Blanco mill, Guanajuato, Mexico showing lined tailings pond The Company had mined a property in the late 1980 s known as “Sierra Guadalupe” in the State of Zacatecas. To our knowledge, there were no documented reports of on the geology, reserves, or production. Currently, the property is being mined by a third party who is delivering 2. 5 to 5% mill feed at a rate of up to 1, 000 tpm. They can produce up to 3, 000 tpm when underground operations are resumed. USAC claims no reserves at this property. USAC is sourcing mill feed and Direct Shipping Ore (DSO) for Madero from the Soyatal District in the State of Queretaro, Mexico. The deposit was the third largest producer in Mexico. Donald E. White (U. S. Geological Survey Bulletin 960 -B, Antimony Deposits of Soyatal District, State of Queretaro, Mexico, 1948) prepared an extensive report and said that the production (p. 40) was estimated through 1943 at 25, 630 metric tons of metal contained. USAC has an option to buy this property but claims no reserves. RS – NOVEMBER, 2012 14

SMELTING THOMPSON FALLS SMELTER, MONTANA The Thompson Falls smelter produces antimony oxide, metal, and antimony tri-sulfide from sources around the world including the Madero smelter in Mexico. Aerial view of Antimony, Silver and Gold Smelter RS – NOVEMBER, 2012 Using antimony metal as a feed, the plant is capable of producing 12, 000 ppy (pounds per year) of finished oxide. 16

MADERO SMELTER, COAHUILA, MEXICO USAC is in the process of doubling the smelter capacity with the goal of completion by the end of 2012. The capacity to produce will depend on the grade of the feed. With low grade 20 -25% feed, the furnaces will produce 2, 000 to 3, 000 pounds per day (ppd) of contained antimony metal. With high-grade feed, such as flotation concentrates, the plant will produce 8, 000 to 10, 000 ppd of contained antimony metal. More furnaces will be added in Madero Smelter, Coahuila, Mexico the future if supported by market conditions. Smelter feed is being provided by several satellite mines and also by the USAC flotation-gravity mill at Puerto Blanco. USAC is also sourcing direct shipping ore (DSO) from the San Jose Mines near Wadley, San Luis Potosi, Mexico. The U. S. Geological Survey Bulletin 946 -E, San Jose Antimony Mines Near Wadley, State of San Luis Potosi, Mexico, 1946, Donald E. White and Jenaro Gonzales R. prepared an extensive report and said the production through 1943 was 57, 612 metric tons of metal contained. USAC claims no reserves at this property. A natural gas pipeline is being installed that is intended to reduce current fuel costs by 78%. Fuel costs are second only to raw materials. RS – NOVEMBER, 2012 17

SILVER AND GOLD SOURCES Silver and gold is shipped from the Thompson Falls plant from resources in Canada and Europe. PRODUCTION Later this year our silver and gold production will begin on a much larger scale from the Los Juarez deposit in Mexico. PAYMENT We are expecting a 92%-94% payment for new precious metal (PM) production. COSTS The Company expects costs for PM will be minimal to include transportation and in some cases casting. Most of the historic production, that will continue, involves no cost.
