Basis of Presentation
1. Basis of Presentation	1. 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 and six month periods ended June 30, 2021 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2021. For further information refer to the financial statements and footnotes thereto in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. Going Concern Consideration At June 30, 2021, the Company’s consolidated financial statements show working capital of approximately $21.6 million and an accumulated deficit of approximately $32.6 million. The Company has incurred losses for the past two fiscal 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 six months 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, 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.

Net loss per share of common stock
3. Income (Loss) Per Common Share	3. Income (Loss) Per Common Share Basic income (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted income (loss) per share reflects the potential dilution that could occur if stock warrants were exercised. The following is a reconciliation of the numerator and denominator used in the basic and diluted computation of net income (loss) per share: Three months ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 Numerator: Net income (loss) available to shareholders $ 324,979 $ (286,445 ) $ (22,672 ) $ (607,490 Denominator: Basic weighted average shares outstanding 106,315,419 70,177,677 99,513,378 69,937,144 Incremental shares 2,381,285 - - - Diluted weighted average shares outstanding 108,696,704 70,177,677 99,513,378 69,937,144 Net income (loss) per common share: Basic EPS $ Nil $ (0.01 ) $ Nil $ (0.01 ) Diluted EPS $ Nil $ (0.01 ) $ Nil $ (0.01 ) For the three months ended June 30, 2021, common stock equivalent shares consisted of stock warrants and were included in the calculation of diluted earnings per share.

Income and Other Taxes
11. Income and Other Taxes	11. Income and Other Taxes Mexican Tax Assessment In 2015, the Mexican tax authority (“SAT”) initiated an audit of the USAMSA’s 2013 income tax return. In October 2016, as a result of its audit, SAT assessed the Company $13.8 million pesos, which was approximately $666,400 in U.S. Dollars (“USD”) as of December 31, 2016. SAT’s assessment was based on the disallowance of specific costs that the Company deducted on the 2013 USAMSA income tax return. The Company engaged accountants and tax attorneys in Mexico to defend its position. The assessment was settled in 2018 with no assessment against the Company. In early 2019, the Company was notified that SAT re-opened its audit of USAMSA’s 2013 income tax return and, in November 2019, SAT assessed the Company $16.3 million pesos, which was approximately $818,000 USD as of June 30, 2021. Management reviewed the 2019 assessment notice from SAT and, similar to the earlier assessment, believes the findings have no merit. The Company engaged a tax attorney in Mexico to defend its position. An appeal was filed by the Company in November 2019 suspending SAT from taking immediate action regarding the assessment. The Company posted a guarantee of the amount in March 2020 as is required under the appeal process. In August 2020, the Company filed a lawsuit against SAT for resolution of the process and, in December 2020, filed closing arguments. Management expects the appeal process to continue through 2021. At June 30, 2021 and December 31, 2020, management assessed the possible outcomes for this tax audit and believes, based on discussions with its tax attorney in Mexico, that the most likely outcome will be that the Company will be successful in its appeal resulting in no tax due. Management determined that no amount should be accrued at June 30, 2021 and December 31, 2020 relating to this potential tax liability. There can be no assurance that the Company’s ultimate liability, if any, will not have a material adverse effect on the Company’s results of operations or financial position. If an issue addressed during the SAT audit is resolved in a manner inconsistent with management expectations, the Company will adjust its current net operating loss carryforward, or accrue penalties, interest, and tax associated with the assessment. Other Taxes In 2016, USAMSA imported coal from the United States to its smelter in Mexico to process Australian concentrates associated with the Hillgrove agreement (Note 12). At that time, the Company applied for and was granted a Maquiladora (IMMEX), in accordance with a Manufacturing and Export Services Industry program offered by the Mexican government to attract and promote foreign investment in Mexico. With the IMMEX, all imported goods to Mexico that are also exported in altered form are exempt from the requirement of paying the 16% tax (IVA). The Company did not pay IVA on any of the imported coal used to process the Australian concentrates. In 2020, the Company was informed by the SAT that it owed the 16% IVA money for all the coal imported for the processing of the Australian concentrates. Additionally, there were penalties and fees that SAT added to the total amount. In late 2020, the Company filed a motion before the Taxpayer’s Defense Agency (PRODECON), but the motion was denied. To avoid exorbitant penalties, the Company elected to pay the assessed amount in early 2021. For the year ended December 31, 2020, the Company recognized an export tax expense of $1,120,730 and accrued a liability for this assessment. The assessment was settled with a payment of $1,120,730 during the three month period ended March 31, 2021.

The Puerto Blanco mill and the Madero smelter at the Company’s Mexico operation bring antimony up to an intermediate or finished stage, which may be sold directly or shipped to the United States operation for finishing at the Thompson Falls, Montana plant. The Puerto Blanco mill in Mexico is the site of our crushing and flotation plant, and a cyanide leach plant which will recover precious metals after the ore goes through the crushing and flotation cycles. A precious metals recovery plant is operated in conjunction with the antimony processing plant at Thompson Falls, Montana, where a 99% precious metals mix will be produced. The zeolite operation produces zeolite near Preston, Idaho. Almost all of the sales of products from the United States antimony and zeolite operations are to customers in the United States, although the Company does have a sales operation in Canada.
