In late November 2014, the Goldstrike mine poured a small but significant bar of gold. At 107 ounces, the pour amounted to just one-eighth the size of a typical doré gold bar, but it marked the first time the mine had produced gold using its patented thiosulfate processing method. In fact, it marked the first time any company in the western world had successfully produced gold using thiosulfate.

Long viewed as a potential alternative to cyanide, which is typically used to recover gold that is trapped inside ore, thiosulfate is a difficult chemical to master. Barrick spent more than two decades perfecting its thiosulfate processing method and relied on an unmatched level of scientific and technological expertise.

“It’s the culmination of years of hard work and a good example of how our partnership culture is manifesting itself on the ground,” says Goldstrike General Manager Andy Cole. “This was a huge initiative, and it would not have succeeded if it weren’t for the collaboration, trust and accountability that developed between our project team, the construction group and the Goldstrike operations team.”
