What Kappes, Cassiday & Associates does

Kappes, Cassiday & Associates (KCA) is a privately held metallurgical engineering firm founded in 1972 and headquartered in Reno, Nevada, specializing in process development, heap leaching, and cyanide processing for the international gold and silver mining industry. The company operates with approximately 80-81 staff, including 35 metallurgical laboratory specialists and 25 process engineers, from a 3,800 square meter headquarters that also houses a 20,000 square foot fabrication facility. KCA delivers an integrated service portfolio spanning metallurgical process testing, scoping and bankable feasibility studies, basic and detailed engineering design, and full Engineering, Procurement and Construction Management (EPCM) services, with documented EPCM contract values ranging from US$53M to US$140M for major projects.

The company's underlying technology combines proprietary equipment with specialized metallurgical expertise developed over more than five decades. Core technical assets include the patented KCA LifterBottle (US Patent No. 9,187,211 B2) for bottle roll leach testing, the KCA Carbon Converter for recovering gold and silver from carbon fines, a pilot-scale ThyssenKrupp Polycom HPGR unit (one of few in North America), and a suite of modular and site-built recovery plants (ADR and Merrill-Crowe configurations), electrolytic cells, smelting furnaces, mercury retorts, and rotary splitters. KCA's laboratory tests over 100 different ore types annually and has supported more than 1,000 gold recovery projects across 70+ process plants in 30+ countries, with unique process expertise spanning the SART process, the world's only primary chloride leaching plant for silver (Itos), and flowsheets for battery-grade manganese sulfate production.

KCA generates revenue through professional services (metallurgical testing, feasibility, engineering, and EPCM contracts), equipment and plant fabrication sales, and procurement/logistics services delivered through its subsidiary Kappes Cassiday del Norte (KCN) in Mexico and affiliate KCA Australia (KCAA). The firm serves both enterprise majors—including Agnico Eagle, Barrick Gold, Kinross, IAMGOLD, Pan American Silver, and SSR Mining—and a growing roster of junior-to-mid-tier explorers. Distribution is direct and sales-led via professional networks, technical conference presentations, and published papers; KCA does not maintain a consumer-facing marketing presence. The company has no public listing, no identified institutional investors, and no parent company.
