THIS SUMMARY focuses on the past history of the Getchell property, its general geology, and current published information relative to gold mineralization. It should provide background and a geologic context for the field tour of Getchell. The Getchell property dates to 1934 gold discoveries, and its history includes some of the earliest open-pit oxide and sul-fide gold production in Nevada. In retrospect, the early gold discoveries were some of the first discoveries of what is now known as sediment hosted, micron gold, Carlin-type deposits. Several other open-pit mines were developed on similar deposits in what is now Nevada’s Getchell gold trend.

Current Getchell Gold Corporation land holdings in the Getchell Trend cover 50 mi2 at the northern end of the Os-good Mountains and the Dry Hills. With the 1991 discovery of the high-grade underground orebodies from the Getchell main (sulfide) open pit and the 1994 discovery and initial shaft development of the underground Turquoise Ridge Deposit, the Getchell Trend is entering a new era of bulk tonnage underground gold mining (Table 1).

Placer Dome merged with the Getchell Gold Corporation in the spring of 1999. Getchell Gold is the mine operator and is currently optimizing the Turquoise Ridge and Getchell mines through predevelopment work for bulk tonnage underground production. Placer Dome is conducting exploration aimed at reserve and resource expansion and the discovery of new deposits in outlying areas of the property.
