1. Basis of Presentation

Accounting Policies [Abstract]
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, 2018 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2018. 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, 2017. Going Concern Consideration At June 30, 2018, the Company’s consolidated financial statements show negative working capital of approximately $2.8 million and accumulated deficit of approximately $27.2 million. In addition, the Company had recurring net losses. These factors indicate that there may be doubt regarding the ability to continue as a going concern for the next twelve months. The continuing losses are principally a result of the Company’s antimony operations and in particular to the production costs incurred in Mexico. Regarding the antimony division, prices improved during 2017 with an average sale price of $4.01 per pound. Through June 30, 2018, the average sale price for antimony is approximately $4.28 per pound. Additionally, in November 2017, the Company renegotiated its domestic sodium antimonite supply agreement resulting in a lower cost per antimony per pound of approximately $0.44. During the first six months of 2018, we endured supply interruptions from our North American supplier, and they have notified us that, due to a lack of raw material, they will be suspending shipments to us from September 17, 2018 to November 5, 2018. We anticipate that normal supply quantities will resume for the remainder of 2018 after November 5. We have been able to continue with operations due to our Mexican raw material, and we will be directing our resources to increasing that supply source. The new supply agreement with our North American supplier has helped us with our cash flow in 2018 from our antimony division. In 2017, we reduced costs for labor at the Mexico locations which has resulted in a lower overall production costs in Mexico which has continued into 2018. In the fourth quarter 2017, we adjusted operating approaches at Madero that has resulted decreased operating costs for fuel, natural gas, electricity, and reagents for 2018. Although total production activity in Mexico decreased in 2017 due to the lack of Hillgrove concentrates, the Company’s 2018 plan involves ramping up production at its own antimony properties in Mexico. We are anticipating agreements that will provide us with operating capital to achieve this (See Note 14). In addition, a new leach circuit expected to come on line during 2018 in Mexico will result in more extraction of precious metals. The portion of the precious metals recovery system at the Madero smelter is complete and the cyanide leach circuit being built at the Puerto Blanco plant is expected to be completed this fall. In 2017, management implemented wage and other cost reductions at the corporate level that has kept administrative costs stable in 2018. The Company expects to continue paying a low cost for propane in Montana through 2018, which in years past has been a major operating cost. Over the past several years, the Company has been able to make required principal payments on its debt from cash generated from operations without the need for additional borrowings or selling shares of its common stock. The Company plans to continue keeping current on its debt payments in 2018 through cash flows from operations while using the additional operating capital to continue with the expansion of our Mexican operation and to improve our working capital. Management believes that the actions taken to increase production and reduce costs, along with the expected additional operating capital, will enable the Company meet its obligations for the next twelve months.

Developments In Accounting Pronouncements
Developments in Accounting Pronouncements	Accounting Standard Updates Adopted In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09 Revenue Recognition, replacing guidance currently codified in Subtopic 605-10 Revenue Recognition-Overall. The new ASU establishes a new five step principles-based framework in an effort to significantly enhance comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets. In August 2015, the FASB issued ASU No. 2015-14 Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. ASU No. 2015-14 deferred the effective date of ASU No. 2014-09 until annual and interim reporting periods beginning after December 15, 2017. We adopted ASU No. 2014-09 as of January 1, 2018 using the modified-retrospective transition approach. There was no impact of adoption of the update to our consolidated financial statements for the three and six months ended June 30, 2018. We performed an assessment of the impact of implementation of ASU No. 2014-09, and concluded it does not change the timing of revenue recognition or amounts of revenue recognized compared to how we recognize revenue under our current policies. Adoption of ASU No. 2014-09 involves additional disclosures, where applicable, on (i) contracts with customers, (ii) significant judgments and changes in judgments in determining the timing of satisfaction of performance obligations and the transaction price, and (iii) assets recognized for costs to obtain or fulfill contracts. See Note 4 for information on our sales of products. In August 2016, the FASB issued ASU No. 2016-15 Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The update provides guidance on classification for cash receipts and payments related to eight specific issues. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. We adopted this update as of January 1, 2018. In November 2016, the FASB issued ASU No. 2016-18 Statement of Cash Flows (Topic 230): Restricted Cash. The update requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. We adopted this update as of January 1, 2018. Cash, cash equivalents, and restricted cash on the consolidated statements of cash flows includes restricted cash of $63,345 as of June 30, 2018 and December 31, 2017 and $63,274 as of June 30, 2017 and December 31, 2016, as well as amounts previously reported for cash and cash equivalents. Accounting Standards Updates to Become Effective in Future Periods In February 2016, the FASB issued ASU No. 2016-02 Leases (Topic 842). The update modifies the classification criteria and requires lessees to recognize the assets and liabilities on the balance sheet for most leases. The update is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. We are currently reviewing our leases and compiling the information required to implement the new guidance. We are currently evaluating the potential impact of implementing this update on our consolidated financial statements.

Net income (loss) per share of common stock:
Income (Loss) Per Common Share	Basic earnings per share is calculated by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated based on the weighted average number of common shares outstanding during the period plus the effect of potentially dilutive common stock equivalents, including warrants to purchase the Company's common stock and convertible preferred stock. Management has determined that the calculation of diluted earnings per share for the quarter and six month periods ended June 30, 2018 and June 30, 2017, is not applicable since any additions to outstanding shares related to common stock equivalents would be anti-dilutive. As of June 30, 2018 and 2017, the potentially dilutive common stock equivalents not included in the calculation of diluted earnings per share as their effect would have been anti-dilutive are as follows: June 30, 2018 June 30, 2017 Warrants 250,000 250,000 Convertible preferred stock 1,751,005 1,751,005 Total possible dilution 2,001,005 2,001,005

Revenue Recognition [Abstract]
Revenue Recognition	Our products consist of the following: ● Antimony: includes antimony oxide, sodium antimonate, and antimony metal ● Zeolite: includes course and fine zeolite crushed in various sizes. ● Precious Metals: includes refined gold and silver For our antimony and zeolite products, revenue is recognized upon the completion of the performance obligation which is met when the transaction price can be reasonably estimated and revenue is recognized generally at the time when risk is transferred. We have determined the performance obligation is met and title is transferred either upon shipment from our warehouse locations or upon receipt by the customer as specified in individual sales orders. The performance obligation is met because at that time, 1) legal title is transferred to the customer, 2) the customer has accepted the product and obtained the ability to realize all of the benefits from the product, 3) the customer has the significant risks and rewards of ownership to it, 4) it is very unlikely product will be rejected by the customer upon physical receipt, and 5) we have the right to payment for the product. Shipping costs related to the sales of antimony and zeolite products are recorded to cost of sales as incurred. For zeolite products, royalty expense due a third party by the Company is also recorded to cost of sales upon sale in accordance with terms of underlying royalty agreements. For sales of precious metals, the performance obligation is met, the transaction price is known, and revenue is recognized at the time of transfer of control of the agreed-upon metal quantities to the customer. Refining and shipping costs related to sales of precious metals are recorded to cost of sales as incurred. Sales of products for the three and six month periods ended June 30, 2018 and 2017 were as follows: Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Antimony $ 1,492,520 $ 2,077,300 $ 3,174,333 $ 4,063,808 Zeolite 682,534 616,414 1,373,240 1,228,426 Precious metals 81,293 144,766 141,703 165,577 $ 2,256,347 $ 2,838,480 $ 4,689,276 $ 5,457,811 The following is sales information by geographic area based on the location of customers for the three and six month periods ended June 30, 2018 and 2017: Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 United States $ 1,878,244 $ 2,653,227 $ 4,125,935 $ 4,950,282 Canada 378,103 185,253 563,341 507,529 $ 2,256,347 $ 2,838,480 $ 4,689,276 $ 5,457,811 Sales of products to significant customers were as follows for the three and six month periods ended June 30, 2018 and 2017: For the Three Months Ended For the Six Months Ended June 30, 2018 June 30, 2017 June 30, 2018 June 30, 2017 Mexichem Speciality Compounds $ 669,103 $ 769,998 $ 1,397,681 $ 1,556,423 East Penn Manufacturing Inc. - 363,979 - 512,621 Kohler Corporation 334,778 501,320 651,550 946,498 Ampacet Corporation 146,118 - 330,260 - ZEO, Inc. 185,730 - 306,701 - $ 1,335,729 $ 1,635,297 $ 2,686,192 $ 3,015,542 % of Total Revenues 59.20 % 57.60 % 57.30 % 55.30 % Accounts receivable from largest customers were as follows for June 30, 2018 and December 31, 2017: June 30, 2018 December 31, 2017 Nutreco Canada, Inc. $ - $ 25,657 Ralco Mix Products - 16,000 Mexichem Speciality Compounds 148,211 - Axens North America, Inc. 38,404 - Teck American, Inc. 82,733 241,627 $ 269,348 $ 283,284 % of Total Receivables 58.40 % 78.10 % Our trade accounts receivable balance related to contracts with customers was $461,291 at June 30, 2018 and $362,579 at December 31, 2017. Our products do not involve any warranty agreements and product returns are not typical. We have determined our contracts do not include a significant financing component. For antimony and zeolite sales contracts, we may factor certain receivables and receive final payment within 30 days of the performance obligation being met. For antimony and zeolite receivables not factored, we typically receive payment within 10 days. For precious metals sales, a provisional payment of 75% is typically received within 45 days of the date the product is delivered to the customer. After an exchange of assays, a final payment is normally received within 90 days of product delivery.

Notes to Financial Statements
Accounts Receivable and Due to Factor	The Company factors designated trade receivables pursuant to a factoring agreement with LSQ Funding Group L.C., an unrelated factor (the “Factor”). The agreement specifies that eligible trade receivables are factored with recourse. We submit selected trade receivables to the factor, and receive 83% of the face value of the receivable by wire transfer. The Factor withholds 15% as retainage, and 2% as a servicing fee. Upon payment by the customer, we receive the remainder of the amount due from the factor. The 2% servicing fee is recorded on the consolidated statement of operations in the period of sale to the factor. John Lawrence, CEO, is a personal guarantor of the amount due to Factor. Trade receivables assigned to the Factor are carried at the original invoice amount less an estimate made for doubtful accounts. Under the terms of the recourse provision, the Company is required to reimburse the Factor, upon demand, for factored receivables that are not paid on time. Accordingly, these receivables are accounted for as a secured financing arrangement and not as a sale of financial assets. The allowance for doubtful accounts (if any) is based on management’s regular evaluation of individual customer’s receivables and consideration of a customer’s financial condition and credit history.

Related Party Transactions [Abstract]
Income Taxes	During the three and six months ended June 30, 2018, and the year ended December 31, 2017, the Company determined that a valuation allowance equal to 100% of any deferred tax asset was appropriate, as management of the Company cannot determine that it is more likely than not the Company will realize the benefit of a net deferred tax asset. The net effect is that the deferred tax asset is fully reserved for at June 30, 2018 and December 31, 2017. Management estimates the effective tax rate at 0% for the current year. 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. Approximately $285,000 USD of the total assessment is interest and penalties. SAT’s assessment is based on the disallowance of specific costs that the Company deducted on the 2013 USAMSA income tax return. These disallowed costs were incurred by the Company for USAMSA’s business operations. SAT claims that the costs were not deductible or were not supported by appropriate documentation. At June 30, 2018, the assessed amount is $694,752 in U.S dollars. Management has reviewed the assessment notice from SAT and believes numerous findings have no merit. The Company has engaged accountants and tax attorneys in Mexico to defend its position. An appeal has been filed. At December 31, 2016, management estimated possible outcomes for this assessment and believes it will ultimately pay an amount ranging from 30% of the total assessment to the total assessed amount. The Company’s agreement with the tax professionals is that the professionals will receive 30% of the amount of tax relief they are able to achieve. At December 31, 2016, the Company accrued a potential liability of $410,510 USD of which $285,048 was for unpaid income taxes, $75,510 was for interest expense, and $49,952 was for penalties. The amount accrued represents management’s best estimate of the amount that will ultimately be paid. The outcome could vary from this estimate. For the three and six months ended June 30, 2018, the Company recognized a $62,752 and $12,752 decrease, respectively, and for the three and six months ended June 30, 2017, recognized a $51,642 and $10,191 decrease, respectively, due to the change in exchange rates. Fluctuation in exchange rates has an ongoing impact on the amount the Company will pay in U.S. dollars. If an issue addressed during the SAT audit is resolved in a manner inconsistent with management expectations, the Company will adjust its net operating loss carryforward, or accrue any additional penalties, interest, and tax associated with the audit. The Company’s tax professionals in Mexico have reviewed and filed tax returns with the SAT for other tax years and have advised the Company that they do not expect the Company to have a tax liability for those years relating to similar issues.
