Americas Gold and Silver Signs Joint Venture Agreement with US Antimony to Construct Antimony Processing Facility in Idaho's Silver Valley - Unlocking Value from Its Antimony Production and Strengthening U.S. Critical Mineral Security
Americas Gold and Silver pivots from silver miner to critical mineral powerhouse through Idaho antimony JV

The February 10, 2026, announcement details a definitive joint venture (JV) agreement between Americas Gold and Silver (USA) and United States Antimony Corporation (UAMY). The objective is to construct and operate an antimony processing facility in Idaho’s Silver Valley. USA will hold a 51% majority stake, while UAMY will hold 49% and act as the operator. Americas is contributing the site at its 100%-owned Galena Complex and providing the antimony feed material. UAMY provides technical and marketing expertise. This facility aims to capture downstream profits from antimony production that were previously lost under standard offtake terms where antimony was treated as a byproduct or even a penalty element.
This news is a significant strategic evolution for the company. Historically, Americas focused on silver, lead, and zinc. By securing a JV for a dedicated processing plant, the company is verticalizing its antimony business. - Revenue Enhancement: In 2025, the company produced 561,000 lbs of antimony. Under the new JV, USA will be paid market rates for the raw feed and capture 51% of the processing profits. - Strategic Positioning: The company is leveraging its status as the "largest antimony producer in the U.S." during a period of heightened concern over domestic critical mineral security. - Capital Commitment: While specific budget figures were not disclosed, capital contributions are based on ownership. Given the recent US$132 million financing, the company appears well-funded for this initiative. - Synergy: This follows the 2025 acquisition of the Crescent Mine, which also contains antimony, providing a centralized hub for Idaho-based critical minerals.
Americas Gold and Silver is a North American miner with two main operational hubs: the Galena Complex in Idaho (100% owned as of Dec 2024) and the Cosalá Operations in Mexico. The Galena Complex is the flagship, having produced over 20 million pounds of antimony historically. The company is transitioning toward becoming a silver-dominant producer (targeting 80% silver revenue) while maximizing high-grade critical mineral byproducts (Antimony and Copper).
