Bayhorse Silver Submits Silver/Copper/Antimony Concentrate Samples From Its Bayhorse Silver Mine To Allihies Engineering For Antimony Leach Testing

Core Viewpoint - Bayhorse Silver Inc. has submitted flotation concentrate samples from its Bayhorse Silver Mine for antimony leach testing, aiming to enhance the recovery of critical minerals including silver, copper, and zinc through a proprietary leaching process developed by Allihies Engineering [1][5][10]. Group 1: Company Developments - Bayhorse Silver Inc. submitted samples from its silver-copper-antimony rich Bayhorse Silver Mine in Oregon to Allihies Engineering for testing using their proprietary antimony leaching technology [1]. - The company has a 100% interest in the Bayhorse Silver Mine, which has a National Instrument 43-101 inferred resource of 292,300 tons at a grade of 21.65 opt (673 g/t) for 6.3 million ounces of silver [13]. - The Bayhorse exploration model suggests that the mineralization extends to the adjacent Pegasus porphyry copper prospect, indicating potential for further resource discovery [7]. Group 2: Mineral Recovery and Testing - Allihies Engineering's leaching tests on similar mineralization confirmed extraction rates of up to 99% for antimony, which could significantly improve recovery rates for the minerals at the Bayhorse Silver Mine [2]. - The dominant mineralization at the Bayhorse site is primarily tetrahedrite, which is refractory in nature, presenting challenges for silver extraction [3][4]. - Previous metallurgical tests achieved silver/copper concentrate recoveries of 86.7%, resulting in a silver grade of 9,700 g/t, alongside significant copper and zinc recoveries [9]. Group 3: Market Context and Pricing - The silver, antimony, copper, and zinc at the Bayhorse Silver Mine are recognized as critical and strategic minerals in the U.S., with current market prices quoted for antimony at US$8.24/lb, copper at US$4.65/lb, zinc at US$1.40/lb, and silver over US$52/oz [5]. - The company plans to review the pricing of all recoverable metals in future cost/benefit analyses for proposed mining operations [5][6]. Group 4: Operational Insights - The company has established a processing facility capable of handling up to 200 tons/day, utilizing a Steinert Ore-Sorter to reduce waste rock by up to 85% [13]. - The successful implementation of the Allihies leaching process could significantly alter the company's original cost-benefit calculations regarding mining operations [6][10].
