I am a economic geologist (hard rock mining) that got my master's degree in PGC/Copper mining. Neat article. Their recovery rate of gold is low at 80% and should be around 90-94%. Up at Red Lake in Ontario, and also Sudbury, mining recovered 93% gold. And the article is true, mining companies use cyandie to recover the gold.
Briefly, cyanide is the only thing known to dissolve cold into solution. Once the gold is in solution the cyanide is then run over steel rods with steel wool attached to them, which uniquely enough the steel wool leaching the gold back out of solution and into the solid state again. It is a simple process then to collect the gold off the steel wool. However, cyanide is bad for the environment and humans. There has been instances of cyanide releasing into streams. About a year ago, a holding pond of cyanide broke and 1,000 of gallons flowed down into the local river killing everything (fish, plants, etc) for over 100 miles. The cleanup cost put the company out of business.
My best guess right now - is to use the new hydrometallurgical process that uses water and gravitation separation for PGE (platinum group elements) minerals.

Good luck to both of you.
If you get the 10 Mil maybe you will want to have a giveaway..?
