This was amplified by the move toward simplified, low-capital plants with low manning levels and automated processes. This drove down operating costs, which in turn made possible the treatment of lower-grade ores. This is typified by the low-grade oxide orebodies of Western Australia, many with head grades around 1 g/t.

A commerative gold ingot from the first gold pour using our cyanide-free recovery method. The infrastructure for a processing plant that uses cyanidation typically costs $30 million, and is therefore, a barrier to entry for gold miners with smaller deposits that do not fit into the large-scale economies of gold production.
