Newsroom 2017

Forward Looking Statements:

December 3, 2018. Thompson Falls, Montana. United States Antimony Corporation (“USAC”, NYSE American “UAMY”) reported that most of the equipment for the Puerto Blanco leach plant is being installed at the Puerto Blanco mill in Mexico.  Projects underway include finishing the tailings pond, wiring, plumbing, and completing the building. A fire assay lab with an atomic adsorption spectrophotometer to analyze gold, silver, and other elements is being assembled to provide quick results at the mill and confirm recoveries. Reagents and supplies are being sourced.

For the first time, two truckloads of Wadley ore were delivered to the Madero smelter in one week. Although this will probably not happen each week at the present time, it is the objective prior to the installation of the compressors. The compressors and pneumatic hammers should be delivered to the Wadley mine in January and are expected to increase production substantially.

The dismantling and transportation of the Great Lakes Chemical Corporation, LANXESS Holding Company US Inc. antimony plant in Reynosa, Mexico is expected to be completed by the end of January 2019. As previously reported, the real property has been sold, and much of the equipment will be used at other USAC properties.

Estimated production for November 2018 was as follows:

The average Rotterdam price for antimony metal during November 2018 was $8,089 per ton or $3.669 per pound.

November 5 2018. Thompson Falls, Montana. United States Antimony Corporation (“USAC”, NYSE American “UAMY”) reported that most of the equipment for the Puerto Blanco leach plant has been built in Montana and is ready to transport. Projects remaining include finishing the tailings pond, wiring, plumbing and completing the building. Hopefully, testing should begin at the end of this year. The Los Juarez gold, silver, and antimony property is regarded as potentially the largest corporate asset and has been on hold due to metallurgical and permitting delays.

At the Sierra de Guadalupe Mines in Zacatecas, Mexico there are now eight contractors and we believe more on the way. Production could eventually rival Wadley which is geologically very similar. At the Soyatal District in Queretaro, Mexico, mining has been slower due to the need for explosives. An explosives license is being pursued. Equipment is being delivered to the Wadley Mine to increase production. The latest acquisition is a -5 ton truck to transport ore from the mine down to the Herradura mill for crushing and sampling. The mine delivers a load of ore each Monday to Madero. 

Progress on the dismantling and transportation of the Great Lakes Chemical Corporation, LANXESS Holding Company US Inc. antimony plant in Reynosa, Mexico is estimated at 50% completion.

Estimated production for September and October 2018 is as follows:

Despite a reduction in raw material supplies from North America, USAC has sustained production as a result of our Mexican mines.

The average Rotterdam price for antimony metal during October 2018 was $8,293 per ton or $3.76 per pound. The average price during September 2018 was $8,393 per ton or $3.80 per pound, a decrease of 1.06%.

At the Sierra de Guadalupe Mines in Zacatecas, Mexico mining has begun in the Santa Fe drift which is oxide with grades of 30-45% antimony. The direct shipping ore (DSO) is now being sent directly to the Madero smelter in Coahuila. Moving forward at Sierra de Guadalupe, the next mine to be opened is the Santa Monica where the ore is primarily sulfide which can be upgraded to a high grade 60-70% antimony floatation concentrate at the USAC Puerto Blanco mill  to make antimony tri-sulfide for the production of primers in all center-fired ordnance. The mines are equipped with load-haul-dump equipment (LHD), compressors, drills, and explosives.

At the Soyatal District in Queretaro, Mexico, 35 to 45% DSO is being mined and shipped to the Puerto Blanco mill for crushing and sampling and is then shipped to the Madero smelter. An explosives license is currently being pursued.

The Wadley Mine in San Luis Potosi, Mexico is now producing one 20 metric ton truck per week of 35 to 40% antimony DSO that is crushed and then shipped to Madero. Current progress is being made to rehabilitate the main drift, the “General Level,” with LHD equipment to increase mill feed. Simultaneously, preparations are being made to install a power line and 200- horsepower compressor. The improvements will allow the use of pneumatic chipping hammers in the mine further increasing production..

Progress on the dismantling and transportation of the Great Lakes Chemical Corporation, LANXESS Holding Company US Inc. antimony plant in Reynosa, Mexico is estimated at 25% completion. Most of the equipment will be used at  USAC Mexican mines and plants and also in the United States for operations in Montana and Idaho. When the plant is stripped of all production equipment, the 184,213 square feet of buildings including a two- story office building, and large warehouse with four loading docks occupying approximately seven acres zoned commercial will be listed for sale. An additional eight acres will be listed for sale as residential property.  

Construction of the cyanide leach plant for the Los Juarez gold/silver/antimony plant at the Puerto Blanco Mill in Guanajuato is on schedule and should allow pilot testing during Q4 of 2018. Much of the equipment from Reynosa will be used at the project. At the same time, progress continues on the 400- metric ton per day mill for the Los Juarez project.

Estimated sales for Q3 of 2018 and actual sales for 2017 are as follows:

The decrease in the production of antimony, silver and gold in 2018 was a result of a 42% reduction in raw material supplies from North America.

The average Rotterdam price for antimony metal during Q3 2018 was    

$8,077.73 per ton or $3.66 per pound. The average price during Q3 2017 was $8,310.15 per ton or $3.789 per pound a decrease of $0.135.

September 10, 2018. Thompson Falls, Montana. United States Antimony Corporation (“USAC”, NYSE American “UAMY”) reported major plans to increase the production of antimony, gold and silver from Mexico.

On August 31, 2018, USAC closed on a Member Interest and Share Capital Agreement between and among Great Lakes Chemical Corporation, LANXESS Holding Company US Inc., the “seller”, and USAC, the “buyer.” The Seller has paid USAC $1,500,000 to dismantle and transport all the equipment and cleanup an antimony plant in Reynosa, Mexico which has become the property of USAC. The weight of the equipment has been estimated at 1,500 tons, and it will involve numerous large cranes and heavy equipment and has been estimated to take six months to complete. The trucking will involve more than 50 truckloads. The equipment will be used at all USAC Mexican mines and plants and also in the United States for operations in Montana and Idaho.

At the Wadley Mine in San Luis Potosi, the main drift, the “General Level” will be reactivated by cleaning up the waste with an Eimco 911 load-haul-dump (LHD) loader and Plymouth locomotive with cars. This will provide access and transportation of the lower grade for the mill that has not been run for more than a year. Simultaneously, a larger primary power line and transformer will be installed to run a 200 horsepower compressor. This will allow the use of pneumatic chipping hammers in the mine. These two steps could double production.

The Santa Monica drift at Sierra de Guadalupe in Zacatecas will be restarted. The mine is equipped with an Eimco 911 LHD, several compressors, drills, and an explosives license. The ore is primarily sulfide and can be upgraded to a high grade 60-70% antimony floatation concentrate at the USAC Puerto Blanco mill  to make antimony tri-sulfide for the production of primers in all center-fired ordnance.  The higher grade sorted ore (direct shipping ore or “DSO”) will ship to the USAC smelter at Madero. There are no records from previous production at Guadalupe, but the deposit is very similar in geology and size to Wadley.

At the Soyatal District in Queretaro, Mexico, a buying program will be started to purchase DSO for the Madero smelter. The District rivaled Wadley production in the past and is expected to go to sulfides at depth that can be milled at Puerto Blanco.

Construction of the cyanide leach plant for the Los Juarez gold/silver/antimony plant should allow pilot testing to commence during Q4 of 2018. Installation of the tailings pond liner should begin by the end of September 2018. Meanwhile the construction of the leach tanks, acid wash circuit, elutriation circuit, Merrill Crowe plant, and carbon regeneration kiln are underway in Montana. Much of this equipment will be ready to put on the new floor of the leach plant during October. The Los Juarez deposit is an open pit bulk-mineable property with a grade of approximately $125.00 per metric ton. The mineralized zone has a strike length of 3.5 kilometers and a width of more than 1 kilometer. Following the confirmation of the beneficiation, a drill program will be initiated and the installation of the 400- ton mill will be resumed.  

When installed, the equipment from the Reynosa plant will increase the capacity of the Madero Smelter in Coahuila, Mexico to approximately 30,000,000 pounds per year of antimony oxide.

Estimated sales for the month of August 2018 were as follows:

The average Rotterdam price for antimony metal during August 2018 was $7,995.45 per ton or $3.626 per pound. The price has been increasingly slowly in Q3 2018.

During the construction period, the Montana metallurgical lab has been busy testing and confirming the metallurgy. Three technical discoveries were made that will expedite long term processing and cut cash costs substantially.

Estimated sales for the month of July 2018 were as follows:

The average Rotterdam price for antimony metal during July 2018 was $7,927.27 per metric ton or $3.595 per pound.  

July 2, 2018. Thompson Falls, Montana. United States Antimony Corporation (“USAC”, NYSE American “UAMY”) reported successful testing of a new product, antimony tri-sulfide (also called “needle antimony” or “crudum”). The product is used as a primer component in center- fired ordnance. China has historically been the principal source of the product in the United States and most other countries. The USAC antimony tri-sulfide has complied with the military specification of MIL-A-159D. The product is now being offered to commercial manufacturers of ordnance. USAC will source the antimony ore from one of its Mexican mines and it will be transported to its floatation mill in Guanajuato, Mexico. The floatation concentrate will be shipped directly to Montana for processing. The processing cost using a proprietary method developed by USAC will be cheaper than the production of antimony metal or oxide. Additionally, the price for the contained antimony is significantly higher than that in antimony oxide or antimony metal.   Besides the ordnance market, a larger market for the product is in the friction brake industry. The Company has received request for the product from Japan and Europe.

Antimony has always been considered a “strategic metal” during wars. The USAC Stibnite Mine in Thompson Falls contributed antimony during World Wars I and II and the Korean and Viet Nam Wars. Antimony metal is used to harden lead in bullets and heavy duty military batteries for vehicles, tanks, ships, and submarines. Antimony oxide is used as a flame retardant in plastics in aircraft, ships, and vehicle interiors and in insulation on electrical wire. Antimony tri-sulfide is used for ordnance primers, tracer bullets, pyrotechnics, and for friction brakes. On May 18, 2018, the Department of Interior named antimony as a “critical commodity” for the “Nations security and economic prosperity.”

The construction of the cyanide leach-plant for the processing of the Los Juarez gold/silver/antimony ore is on schedule for testing during Q4, 2018. 

Estimated sales for the month of June 2018 were as follows:

The average Rotterdam price for antimony metal during June was $8,207.14 per metric ton or $3.722 per pound.  

June 4, 2018. Thompson Falls, Montana. United States Antimony Corporation (“USAC”, NYSE American “UAMY”) reported initial testing of the Los Juarez gold/silver/antimony floatation concentrates in Montana. Following is a flow diagram of the operation:

The Los Juarez mine, Puerto Blanco mill, and Madero smelter are operational and the cyanide leach plant is being constructed.  Gold, silver and antimony are being recovered from the Los Juarez flotation concentrates in Montana on a test basis. Testing of the plant is anticipated in Q4 2018.

On May 18, 2018 the Department of Interior published the Final List of Critical Minerals 2018 stating “The United States is heavily reliant on import of certain mineral commodities that are vital to the Nation’s security and economic prosperity.” The list names antimony as a “critical commodity”.

BRZ zeolite orders for most applications were up again in May, but the plant had a maintenance problem that delayed production of more than 300 tons that had been ordered. We anticipate filling these orders by the end of Q2, 2018

Estimated sales for the month of May 2018 were as follows:

The average Rotterdam price for antimony metal during May was $8,114.00 per metric ton or $3.68 per pound. USAC generally sells antimony contained for more than $4.00 per pound. Mexican production exceeds our North American supply.

CEO John Lawrence said “We are excited to start the shake down of the Los Juarez pilot plant in Q4 2018 and to continue construction of the 400 ton mill. We expect to announce our progress on several additional strategic and financial opportunities that do not involve dilution of any kind.”

About U.S. Antimony

US Antimony is a growing, vertically-integrated natural resource company that has production and diversified operations in precious metals, zeolite and antimony. 

Estimated sales for the month of April 2018 were as follows:

April 2, 2018. Thompson Falls, Montana. United States Antimony Corporation (“USAC”, NYSE American “UAMY”) reported 90,000 pounds of antimony production from Mexico that has very low impurities. In Montana, this production is converted to antimony trioxide a flame retardant and also metal that is used in lead alloys such as ordnance in Montana. Antimony raw materials from the North American source cannot be converted to metal due to impurities. We negotiated a new supply agreement with our North American raw material supplier that will result in cost reductions of more than $.40 per pound.  This could result in a cash savings of approximately $600,000 in 2018 for us. 

Progress on the construction of the cyanide leach plant for the Los Juarez gold-silver-antimony deposit in Queretaro, Mexico continues with the preparation of the tailings pond, leach plant floor, and carbon circuit. Initial production is anticipated in Q4 2018.

BRZ zeolite sales for water filtration, animal feed, air filtration, and numerous other applications were up sharply in March.

Estimated sales for the month of March 2018 were as follows:

CEO John Lawrence said “We are excited about the increased cash flow from the new antimony supply agreement, increased Mexican antimony production, and increased BRZ zeolite sales. We expect to announce our progress on several additional strategic and financial opportunities that do not involve dilution of any kind.

After the successful testing of the leach circuit, the production will be ramped up to the 100 ton per day mill capacity.

Commodity prices for February were as follows:

Antimony sales were 135,896 pounds or 177% greater in January 2018 than December 2017 due to the fact that customers do not want large inventories at year end. USAC’s Mexican production has been more meaningful as the North American supply of raw materials has slowed down.

Zeolite sales were 428 tons or 47% greater in January 2018 than in December 2017 due to new orders and customers. The BRZ zeolite has out- performed other domestic and Canadian zeolites producers and has been chosen for nuclear remediation and the removal of ammonium from water. Orders for BRZ are strong for the first half of 2018.    

Commodity prices for January 2018 were as follows:

Construction of the pilot cyanide leach circuit at the Puerto Blanco mill for the leaching of the Los Juarez gold and silver tailings continues making progress. After the successful testing of the leach circuit, the production will be ramped up to the 100 ton per day mill capacity. Thereafter, work will begin on the 400 ton per day mill, and the same leach circuit can be expanded to accommodate the 400 ton per day mill at a minimal expense. 

CEO John Lawrence said “We are excited about the sharp increase in antimony and zeolite sales in January and the startup of gold and silver production from Los Juarez. We are still working on several strategic and financial opportunities presented to the Company that do not involve dilution of any kind.”

 Estimated sales for the month of December 2017 were as follows:

Antimony sales were lower in December as an additional 98,851 pounds had been produced, but the customers did not want to take delivery until the first of 2018 due to inventory reasons. Otherwise, the antimony production would have been 175,719 pounds for the month. During December, USAC only received raw materials from North America containing approximately 36,600 pounds of antimony due to supplier maintenance issues. Normally this would have been approximately 110,000 pounds. Mexico provided raw materials containing approximately 44,284 pounds. In December, Mexico provided 55% of the raw materials.

Zeolite sales would have been higher, but a shortage of trucks prevented the delivery of another 451 tons of finished product.

Estimated sales for 2016 and 2017 we as follows:

Antimony production in 2017 was down due to the loss of raw materials from Australia.

Commodity prices for the year were as follows:

Construction of the cyanide leach tailings pond at the Puerto Blanco mill for the leaching of the los Juarez tailings is underway for the placement of the plastic membrane. Equipment for the leach plant is being built in Montana.

CEO John Lawrence said “We are excited about the commencement of construction of the pilot leach plant for Los Juarez. Additionally, the Company added 30 new customers for the BRZ zeolite, and we expect to see sales grow during 2018. In the near future, we expect to announce our progress on several additional strategic and financial opportunities presented to the Company that do not involve dilution of any kind.
