NEVADA 1984 The Dee Gold Mine in Elko County, Nevada, was discovered in 1980 by Whit Delamare, an employee of Cordex Exploration Co. In 1982, a feasibility study was commissioned, and in 1983, the decision to start production was made. The mine began producing mill-grade ore in 1984, and a heap leaching operation for lower-grade ore commenced on June 1, 1985. In the 1980s, it was owned by the Cordex Syndicate, with stakeholders including Rayrock Yellowknife Resources (44%), International Corona Corp. (44%), and John S. Livermore (12%). The mine had a small output. Ownership changed to Glamis Gold, Ltd. in 2002, and its last year of production was in 2001.

However, this event was followed by a significant turn of events later that year. Johnson Matthey's banking and gold-trading division, Johnson Matthey Bankers Ltd, suffered a catastrophic collapse on September 30, 1984, less than a year after the notorious Brink's-Mat robbery. During this audacious heist, a staggering £26 million worth of gold bullion, diamonds, and cash were pilfered from a Brink's-Mat warehouse. Notably, the purloined bullion belonged to Johnson Matthey Bankers Ltd, and to this day, most of the gold remains unrecovered.
