Can gold miners say 'sayonara' to cyanide?

The company is targeting small to medium scale miners that can't afford a conventional cyanide plant or want to avoid using cyanide. According to CSIRO, the cost of a typical cyanide-based processing plant is around $30 million, but the new technology, which is scalable, can cost as little as $2-2.5 million.
