There’s something alchemical about extracting precious gold using deadly mercury and cyanide. But for the many who work in artisanal and small-scale mining (ASM), this bit of alchemy is a grim reality that often results in mercury or cyanide poisoning, death, and environmental degradation.

In the alchemy of social change, technology is only one part of the formula. The other, arguably more complex part, is people. This can be seen in the journey to bring the technology dubbed CLINN-GEM, or the Community-Led Integrated Non-Cyanide Non-Mercury Gold Extraction Method, out of project leader Dr. Herman D. Mendoza’s laboratory at the UP Department of Mining, Metallurgical and Materials Engineering, and into the communities and day-to-day lives of the country’s artisanal and small-scale miners (ASMs).
