Joralemon (1951) observed microscopic metallic grains in the Getchell ore that he concluded were native silver, although the particles were so small that conclusive chemical tests were not possible. Lone Tree is an open pit operation and was acquired through the Santa Fe merger and began operations in 1991. The NNW trending faulting of the Getchell Fault Zone post dates east-west crossing structures, but pre-dates, or is contemporaneous with, north-east and north-west trending structures and joint swarms. Converted from S&A FileMaker format to Oracle. Open pit mining occurred on the property between 1980 and 1999 and underground test mining (the Pinson Mine) was conducted in the early 2010s. Modeling of gold grade shows that much of ore at the north end of Turquoise Ridge is hosted by the sedimentary debris flow breccias. This agreement is the formal start of Phase 2 with Barrick, after the implementation during 2022 of Nevada . No other silver minerals have been recognized except for very rare grains of electrum. Heap leaching of waste rock dumps from previous mining operations commenced at the end of fiscal 1985, producing 91 ounces of gold in that fiscal year. Gold is micron-scale generally intergrown with arsenical pyrite, which in turn, is encrusted in barren, diagenetic pyrite. Nevada Gold Mines, LLC Barrick Turquoise Ridge, Inc.

The basin margin is defined by a sharp, N60-70?W-trending southern margin to a lower sequence of pillowed basalt and underlying sedimentary breccias. Table of contents The monocline is interpreted to have formed by syn-depositional normal movement along a buried WNW-trending fault. Metals Mined: Gold, Copper, Silver The Turquoise Ridge Underground deposit is a typical Carlin-type deposit and is characterized by structurally and stratigraphically controlled, sediment-hosted, replacement deposits containing micron-sized gold. The low-angle faults and associated folds are the result of Devonian and Permian-age compressional events and the higher angle faults and fracture sets formed during Tertiary extension. Metals Mined: Gold Prior to July 1, 2019 Twin Creeks production was included within our Newmont Nevada mine profile. Conoco subleased the property from 1975 to 1978 to General Electric Co. who conducted tungsten exploration along the margins of the Osgood Stock. Geochemical work at the Getchell mine and vicinity has demonstrated that As-W-Hg anomalies occur in rocks and soils over the arsenic-gold deposits and that these anomalies are not broad haloes but are restricted to the mineralized area. Nevada Gold Mines is a joint venture between Barrick Gold Corporation (61.5%) and Newmont Goldcorp Corporation (38.5%), combining their significant assets across Nevada to create the.
