Since 1972, Kappes, Cassiday & Assocaites (KCA) has provided process metallurgical services to the international mining industry. KCA specializes in all aspects of heap leach and cyanide processing, including laboratory testing, project feasibility studies, engineering design, construction, and operations management.

While primarily known for its heap leach expertise, KCA's staff includes experienced professionals with design capabilities in a wide range of metallurgical processes. KCA has recently engineered a complex acid leach process for a Bolivian silver project. Since 1993, KCA has maintained an active bio-leaching program for several clients with refractory ores, including a program for a major mining company.

For several years, KCA has routinely expanded its client base and service capabilities. KCA occupies a 3800 square meter building in Reno, NV, which greatly increases KCA's capacity for engineering, manufacturing, purchasing, warehousing, and testing. Florin Analytical Services, part of the KCA group, operates as an independent commercial analytical lab, providing high quality, reliable assays.
