All statements of historical fact, included in this presentation are forward-looking statements that involve risks and uncertainties. The words “believe”, “expect”, “anticipate”, “contemplate”, “target”, “plan”, “intends”, “continue”, “budget”, “estimate”, “forecast”, “may”, “will”, “schedule”, and similar expressions identify forward-looking statements. Forward-looking statements include, among other things, statements regarding targets, estimates and assumptions in respect of antimony, zeolite, gold and silver and gold equivalent production and prices, cash and operating costs, results and capital expenditures, mineral reserves and mineral resources and anticipated grades, recovery rates, future financial or operating performances, margins, operating and exploration expenditures, costs and timing of the development of new deposits, costs and timing of construction, costs and timing of future exploration and reclamation expenses, anticipated 2011 results, our ability to fully fund our business model, including our capital and exploration program, internally, anticipated 2011 year-end interim and annual gold and silver production and the cash and operating costs associated with the same, the ability to achieve productivity and operational efficiencies, the ability to achieve cash flow margin improvements, the ability to develop and put into production our exploration targets and the timing of each thereof. Forward-looking statements are necessarily based upon a number of estimates and assumptions that, while considered reasonable by United States Antimony Corporation, are inherently subject to significant business, economic, competitive, political and social uncertainties and contingencies. Important factors that could cause actual results to differ materially from United States Antimony Corporation expectations include, among others, risks related to international operations, the actual results of current exploration activities, conclusions of economic evaluations and changes in project parameters as plans continue to be refined, future prices of antimony, zeolite, silver and gold, known and unknown uncertainties and risks relating to additional funding requirements, reserve and resource estimates, hedging activities, development and operating risks, illegal miners, uninsurable risks, competition, limited mining operations, production risks, environmental regulation and liability, government regulation, currency fluctuations, recent losses and write-downs, dependence on key employees, possible variations of ore grade or recovery rates, failure of plant, equipment or process to operate as anticipated, or accidents. Although United States Antimony has attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such statements will prove to be accurate as actual results and future events could differ materially from those anticipated in such statements. Forward-looking statements are not guarantees of future performance. Accordingly, readers should not place undue reliance on forward-looking statements. GHS July 19, 2011 17
