Overview
The Long Canyon mine is an open-pit gold and silver operation located in Elko County, Nevada, United States, on the eastern flank of the Pequop Mountains. It is part of the Nevada Gold Mines joint venture, owned and operated by Barrick Gold Corporation (61.5%) and Newmont Corporation (38.5%). Mining operations were temporarily ceased in 2022, and the mine was placed on long-term care and maintenance at the end of 2023. In the fourth quarter of 2024, Barrick decided to place the mine into closure.
Production
The mine produced 22,000 ounces of gold in 2016, 174,000 ounces of gold in 2017, 89,988 ounces of gold and 2,054 ounces of silver in 2022, 15,002 ounces of gold and 897 ounces of silver in 2023, and 8,839 ounces of gold and 622 ounces of silver from residual leaching in 2024.
Processing
The primary processing method is a heap leach facility with a carbon-in-column plant. Ore is leached on a synthetically lined pad, and the resulting gold-bearing carbon is transported to Newmont's Carlin facilities for final processing into doré. The facility is permitted to process up to five million tonnes of ore annually.
Equipment
The mining equipment fleet includes blast-hole drills, hydraulic shovels, front-end loaders, and off-highway trucks, supported by dozers, loaders, graders, and water trucks.
Expansion
Plans for a 'Phase 2' expansion of the mine were dropped. Nevada Gold Mines had temporarily suspended expansion plans in August 2020 to conduct further hydrologic studies. In March 2024, Barrick Gold decided not to pursue permitting for the expansion.

Overview
The Twin Creeks mine in Humboldt County, Nevada, is an active gold and silver operation, formed in 1993 by the consolidation of the Chimney Creek and Rabbit Creek mines. It is managed as part of the Turquoise Ridge Complex, operated by Nevada Gold Mines LLC, a joint venture between Barrick Gold Corporation (61.5%) and Newmont Corporation (38.5%). The mine includes both surface open pit operations, such as the Mega Pit and Vista Pit, and an underground component, the Vista Underground mine, which concluded production in May 2024.
Production
In 2023, the mine produced 514,386 ounces of gold and 163,388 ounces of silver. The Turquoise Ridge Complex, including Twin Creeks, produced approximately 500,000 ounces of gold in 2022.
Processing
Ore processing at Twin Creeks includes the Sage Autoclave for refractory ore, the Juniper Oxide carbon-in-leach (CIL) plant, and extensive heap leach facilities. Refractory ore processing involves pressure oxidation, cyanide leaching, carbon adsorption, electrowinning, and refining. The mine is permitted to process up to 15,536,330 tonnes of ore per year through conventional heap leach cyanidation and milling.
Equipment
Sage Autoclave, Juniper Oxide CIL (carbon-in-leach) plant, heap leach facilities
Expansion
The Cut 40 expansion of the Mega Pit involves extending the pit 500 feet to the north and deepening it by 240 feet. Drilling at the southern end of the Mega pit has also intercepted significant mineralisation.

The Carlin Complex in Nevada, United States, is an extensive mining operation and part of Nevada Gold Mines, a joint venture between Barrick Gold Corporation (61.5 per cent ownership) and Newmont Corporation (38.5 per cent ownership). Formed on 1 July 2019, it integrated Barrick's Goldstrike and Newmont's Carlin properties. It is an active operation, comprising both open pit and underground mines, and is a major contributor to Nevada's gold production. The complex includes several major open pit operations such as Goldstrike, Gold Quarry, Goldstar, Rain/Emigrant, and South Arturo, as well as key underground mines like Goldstrike, Leeville, and the Carlin Portal Mines (Pete Bajo, Exodus, El Nino, and Rita K).
Production
Gold production for the Carlin Complex was 1,570,731 ounces in 2022 and 1,411,382 ounces in 2023. Silver production was recorded at 138,921 ounces in 2023 and 33,497 ounces in 2024.
Processing
Ore processing at the Carlin Complex is handled by a series of integrated facilities including the Gold Quarry Roaster, Goldstrike Roaster, Goldstrike Autoclave, South Area Leach, and North Area Leach. Processing methods are diverse, employing roasting, autoclaving, and heap leaching with cyanide to recover gold.
Equipment
The mining fleet for open pit operations includes P&H and Hitachi electric and hydraulic shovels, alongside Komatsu and CAT haul trucks. In October 2023, an agreement was made to purchase 62 new Komatsu 930E-5 haul trucks, with 40 designated for the Carlin Complex. Underground operations utilise a fleet of load-haul-dump units, haul trucks, and various drilling and support machinery.
Expansion
Significant expansion projects are underway to extend the life of the mine and increase production. The Goldrush Underground project is expected to increase gold output to approximately 400,000 ounces per year by 2028. The REN Project, a high-grade underground extension of the Goldstrike Mine, is anticipated to be in full production by 2027, with an average annual output of 140,000 ounces of gold. These expansions are expected to extend the mine's operational life to at least 2038.
