The heat source was magmatic but the exact mechanism is still under debate. Like most Carlin type gold deposits in Nevada the gold was epithermally deposited in carbonate or silicate sedimentary rocks.
Goldstrike is northwest of the Carlin mine on the Carlin Trend. The Goldstrike mine adjoins Newmont Mining's Carlin mine complex. The Goldstrike mine complex comprises the Betze-Post-Screamer and Meikle-Rodeo deposits. Barrick acquired 100% ownership of the property in December 1986, and mining started in 1987. The JV delineated ore reserves for the Post deposit in 1986. In 1978, Western State Minerals Corporation entered into a joint venture (JV) with PanCana. Gold was first mined from the upper, well-oxidized portion of what became the Post deposit in 1975 by PanCana Minerals Ltd., in a small open-pit heap leach operation. The first discovery of gold in the Goldstrike property was in 1962 by Atlas Minerals. Since Barrick acquired Goldstrike in 1986, until 2018 it produced 44.4 million ounces of gold. It is owned and operated by Barrick Gold. It is located on the Carlin Trend, a prolific gold mining district. Goldstrike is a gold mine in Eureka County in north-eastern Nevada.
