en.Wedoany.com Reported - Silver exploration achieves four in-mine discoveries at the operating mine. Americas Gold & Silver announced on April 30, 2026, that its Galena Complex in Idaho's Silver Valley has made its fourth significant discovery in the past 12 months, identifying a total of six new high-grade silver-copper-antimony veins, collectively referred to as the 43L-TJ Vein System Complex. Drilling intercepts include 1.9 meters grading 1,392 g/t silver, 1.5% copper, and 1.5% antimony, and 0.7 meters grading 2,563 g/t silver, 1.8% copper, and 1.4% antimony. These intercepts are located just 25 meters from existing infrastructure on the 4300 Level.
The mine operates within a 130-year-old historic mine complex, with infrastructure distributed between the 2000-foot level and the 6000-foot level. Oliver Turner, Executive Vice President of Corporate Development, stated: "We are not drilling 600-meter-deep holes that take a year to develop; we are talking about in-mine discoveries." The proximity of mineralization to existing facilities eliminates the need for new shafts, ramps, and utilities, significantly reducing development capital. The capital expenditure for the Phase 2 upgrade of the No. 3 Shaft is estimated at only $1.1 million, increasing total hoisting capacity to 1,350 short tons per day, with completion targeted for mid-May 2026. The mill's current processing capacity is 410 to 420 short tons per day, with plans to expand to 1,200 short tons per day by the end of 2026.
The discovery rate in silver exploration continues to enhance value within existing permits. The company previously disclosed the 034 Vein, the 149 Vein System Complex, and the 520 Vein, all located near existing infrastructure, with the 034 Vein's resource growing from an estimated 1 million ounces to over 7 million ounces. In 2026, the company has allocated a $20 million exploration budget, deploying a 64,000-meter drilling program using short holes from underground platforms to rapidly acquire data and directly inform mining sequence decisions. The geological system remains open at depth, with all infrastructure situated between the 2000 and 6000-foot levels, while the neighboring Hecla Lucky Friday mine operates below the 10,000-foot level.
Capacity expansion within the operating mine drives unit cost reduction. The company's 2026 growth capital budget ranges between $60 million and $80 million, with key focuses including the construction of a paste backfill plant (capex of $11.9 million) and the rehabilitation of an idle shaft ($7.3 million) to support the transition to long-hole stoping. The nine completed long-hole stopes, each with a mining width of 1 meter, are expected to reduce mining costs per ton by 40% to 50%. The proportion of long-hole stoping is projected to reach 70% by the end of 2027, supporting multi-year operating cost reductions. The Crescent Mine, acquired in December 2025 and located 9 miles from Galena, is undergoing rehabilitation, including restoring safety systems in three adits, with a 2026 capital budget of $30 million to $40 million, and has already reduced power costs by replacing diesel generation with cable power.
In silver exploration, existing infrastructure redefines the development risk of in-mine discoveries. Brownfield projects offer shorter development timelines, lower capital intensity, and permits already in place compared to greenfield projects. Turner stated: "As these veins continue to extend at depth, the exploration upside is substantial. The Galena Mine will continue operating for decades to come." The economic calculation for each additional ounce is based on built infrastructure, deployed capital, and an operational team already in place. The combination of discovery rate, infrastructure utilization, and capital efficiency makes the economics of brownfield resource conversion significantly different from greenfield project development.
