U.S. Antimony Reports Major Antimony Cost Reductions


THOMPSON FALLS, MT / ACCESSWIRE / August 7, 2017 / United States Antimony Corporation (“USAC”) (NYSE American: UAMY) reported major cost reductions at its Mexican antimony smelter. As a result of metallurgical changes, the Company has drastically cut costs and increased production rates. The approximate reductions for fuel costs are 50%, electricity 55%, and reagents 75%. Maintenance and other costs are being evaluated. Extra manpower will be assigned to processing Los Juarez production. The Company expects to see these lower costs impacting the Company’s reported financials beginning in Q3 2017.



July 3, 2017. Thompson Falls, Montana. United States Antimony Corporation (“USAC”, NYSE MKT “UAMY”) reported that following the milling of 400 metric tons of Los Juarez gold/silver/antimony at the Puerto Blanco mill in Guanajuato, Mexico that it will proceed with the cyanide circuit to increase the recoveries of both the silver and gold from the flotation mill tailings. Initial results of the floatation assays without the cyanide circuit are as follows:

Item Gold Silver Antimony
Heads 0.035 opmt 3.27 opmt 0.652%
Tails 0.016 opmt 1.618 opmt 0.348%
Recovered grade 0.019 opmt 1.65 opmt 0.17%
% recovery 52.8% 49.6% 31.5

(opmt = ounces per metric ton)

The flotation concentrate contained 2.52 opmt gold, 496.4 opmt silver, and 52.0% antimony. The floatation concentrates will be processed by the caustic leach circuit which is operational.

Cyanide testing of the mill tailings has indicated excellent recoveries, and the antimony recovery has been on the order of 70% at lower depths. The estimated recovery of the values after the caustic leach and cyanide circuit of the tailings is as follows:

Metal Assay Recovery Value Value /mt
Gold 0.035 opmt 90% $1,250/oz $39.38
Silver 3.27 opmt 90% $16.50/oz $48.56
Antimony 0.652% 70% $3.90/lb $39.12
Total $127.06

Construction of the cyanide leach circuit for the Puerto Blanco mill tailings will begin when the permit is approved by SEMARNAT (Mexican equivalent of the EPA). Tentatively, the plan is to leach in Mexico and handle the second part of the process in Montana which is expected to cut Capex costs significantly, reduce operating costs, and expedite the start of the circuit.

Following are the sales estimates for Q2 2017 compared to Q2 2016:

Product Q2 2017 Q2 2016 % change
Antimony pounds 505,760 732,802 -31.0
Zeolite tons 3,352 4,218 -20.5
Silver ounces 17,552.32 29,219.25 -39.9
Gold ounces 61.1552 76.09 -19.62

U.S. Antimony Reports Mining in Mexico


THOMPSON FALLS, MT / ACCESSWIRE / April 3, 2017 / United States Antimony Corporation (“USAC,” NYSE MKT: UAMY) reports the following production estimates for Q1, 2017:

Product Q1, 2017 Q1, 2016 % Change
Antimony pounds 591,942 912,841 -35
Zeolite tons 3,356 3,097 +8
Gold ounces, North America 24.6 40.0 -38.5
Gold ounces, Australia 56.3867 34.977 +61.2
Silver ounces, North America 8,639 12,973 -33.4

Q1 2017 antimony production was lower than Q1 2016 due to the end of the processing of Australian concentrates. Since the beginning of 2017, the Company has accelerated the mining at Wadley and Soyatal to compensate for the Australian supply. During Q1 2017, these two properties produced an estimated 200,000 pounds of contained antimony for the Madero smelter. The smelter has only processed 132,092 pounds of metal that is being shipped to the United States as finished metal. During this period, more furnaces were brought on line at Madero.

The Rotterdam price of antimony grade I metal has increased during Q1 2017 from $7,350 per metric ton ($3.33 per pound) to $8,750 per metric ton ($3.97 per pound). USAC will benefit from the increased prices especially with Mexican production.

U.S. Antimony Reports Antimony Prices and Production


THOMPSON FALLS, MT / ACCESSWIRE / March 6, 2017 / United States Antimony Corporation (“USAC”) (NYSE MKT: UAMY) reports significant price increases in antimony and that it has successfully transitioned from custom smelting antimony concentrates at the Madero, Coahuila, Mexico plant to its own mine production. This Company’s antimony business plan is to accelerate production from its Mexican antimony mines with internal cash flow. The mines had been idle for two years.

With its own antimony raw materials, USAC will benefit fully from price increases, rather than just the smelting fees and small percentages of the price increases. Additionally, the company will enjoy lower processing and trucking costs.
