A Au-Hg-Ag occurrence/mine located in sec. 33, T39N, R42E, MDM, 6.6 km (4.1 miles) NE of Adam Peak and 0.8 km (2,600 feet) SSW of the Getchell Mine proper, on private land (located claim, minerals only). Owned & operated by the First Mississippi Corp. (100.00%), Nevada (1987-1991); by Firstmiss Gold, Inc. 2670145 (100.00%), Nevada (1991-1997); and by the Getchell Gold Corp. (100.00%), Colorado (1997). The MRDS database stated accuracy for this location is 500 meters. This mine is on the same property as the Getchell Mine but not connected.
Mineralization occurred between the Cretaceous and Miocene. Carlin-type gold mine. The ore body strikes N25W and dips 67°E at a thickness of 12 meters, a width of 1,000 meters, and a length of 2,100 meters. Ore body No. 1 is disseminated and irregular, and ore body No. 2 is tabular and replacement. The primary mode of origin was hydrothermal. Primary ore control was faulting, and secondary was folding. Control was also exercised by fracturing and lithology. Wallrock alteration included silicification, decarbonization, argillic, chloritic, and sericitization. Local rocks include granitic rocks.
Reserve/resource data: August 1997: The resource at Turquoise Ridge increased by 2.1 million ounces - the total is now 6.4 million ounces Au.
