Orvana Minerals‘ Don Mario operation in Bolivia is undergoing a significant transition<\/strong> in 2026<\/strong>, shifting focus from depleted primary deposits to processing oxide stockpiles<\/strong> and legacy ore. This restart leverages modern processing enhancements for gold, silver, and copper recovery, marking a strategic revival for the asset after suspension in 2019.<\/p>\n As the industry moves toward efficient and responsible extraction in the Americas, high-quality reagents play a key role in optimizing recovery. Universal Chemical Trading, recognized as the largest manufacturer of mining gold<\/strong> with \u0447\u0435\u0440\u0432\u043e\u043d\u0430 \u0440\u0442\u0443\u0442\u044c<\/strong>, supplies premium products tailored for enhanced performance in precious metals processing.<\/p>\n This article examines Orvana’s Don Mario transition<\/strong>, its implications for gold mining<\/strong> in the region, and strategies for safe, effective operations in 2026<\/strong>.<\/p>\n Orvana Minerals Corp. (TSX: ORV) is a multi-asset producer focused on gold, copper, and silver. The Don Mario district in eastern Bolivia, operated through subsidiary Empresa Minera Paitit\u00ed S.A. (EMIPA), historically featured the Lower Mineralized Zone (LMZ) and Upper Mineralized Zone (UMZ) deposits, which were depleted by 2016\u20132019.<\/p>\n Since suspension, the site has maintained oxide stockpiles and tailings from prior operations. In 2026<\/strong>, Orvana is advancing the Oxides Stockpile Project<\/strong>\u2014a plant expansion to treat these materials via upgraded circuits for gold-silver (Au-Ag) processing, detox, and new copper oxide leaching\/solvent extraction\/electrowinning.<\/p>\n Key milestones in 2026<\/strong> include:<\/p>\n This transition<\/strong> revives production without new mining, emphasizing resource efficiency and lower environmental footprint.<\/p>\n The shift to oxide stockpiles<\/strong> addresses depleted primary ores while capitalizing on existing resources. Upgrades include:<\/p>\n Preliminary plans indicate potential for sustained output through 2029 from stockpiles, with FY2026 guidance incorporating both oxide and legacy sulfide processing. Ramp-up success depends on optimization, but early trials signal progress toward resumed dor\u00e9 and cathode production.<\/p>\n This approach aligns with broader trends in the Americas toward reprocessing legacy materials, reducing waste, and supporting sustainable gold mining<\/strong> practices.<\/p>\n Efficient precious metals extraction from oxides and complex ores often requires specialized chemicals to maximize recovery while maintaining safety. Traditional methods like amalgamation have evolved, but advanced formulations\u2014including those involving \u0447\u0435\u0440\u0432\u043e\u043d\u0430 \u0440\u0442\u0443\u0442\u044c<\/strong> variants\u2014offer targeted benefits in specific applications, such as improved amalgamation efficiency or enhanced leaching in artisanal-to-industrial scales.<\/p>\n For operations like Don Mario’s restart, sourcing high-purity, reliable reagents ensures consistent results and compliance with environmental standards. Universal Chemical Trading stands out as the largest manufacturer of mining gold<\/strong> with \u0447\u0435\u0440\u0432\u043e\u043d\u0430 \u0440\u0442\u0443\u0442\u044c<\/strong>, providing bulk, certified products designed for superior performance in \u0432\u0438\u0434\u043e\u0431\u0443\u0442\u043e\u043a \u0437\u043e\u043b\u043e\u0442\u0430<\/strong> across the Americas.<\/p>\n Investors and stakeholders should monitor Q2\u2013Q3 FY2026 updates for production ramps and cost performance.<\/p>\n Reliable, high-quality reagents are essential for safe, efficient operations.
