Basis of Presentation	The unaudited consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America for interim financial information, as well as the instructions to Form 10-Q. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of the Company’s management, all adjustments (consisting of only normal recurring accruals) considered necessary for a fair presentation of the interim financial statements have been included. Operating results for the three month period ended March 31, 2021 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2021.

Going Concern Consideration At March 31, 2021, the Company’s consolidated financial statements show working capital of approximately $21.6 million and an accumulated deficit of approximately $33 million. The Company has incurred losses for the past two years which are principally a result of the Company’s antimony operations due to both depressed antimony prices and production costs incurred in Mexico. To improve conditions, the Company continues searching for areas to reduce these production costs. In the first quarter of 2021, the Company raised net proceeds of approximately $23.3 million from sale of shares of its common stock and approximately $1.8 million from the exercise of stock purchase warrants. These funds have been and will continue to be used for general corporate purposes, working capital, hiring of additional labor, leverage for reducing legacy contracts, a geochemical, geological, and geophysical study of the Los Juarez property, an analysis and survey of the tailings at its Puerto Blanco floatation mill, additional managerial staff at USAC and BRZ headquarters, a revised website including measures aimed at increased visibility for advertising, more labor at its Mexican smelter, repair and improved infrastructure at the Mexican smelter, potential securement of additional antimony mine reserves in Mexico, and improvement of furnaces in Montana. With the funds raised, management believes the Company has sufficient funds to sustain its operations and meet its financial obligations during the 12 months following the date of issuance of these consolidated financial statements.

At March 31, 2021, the Company’s consolidated financial statements show working capital of approximately $21.6 million and an accumulated deficit of approximately $33 million.
