South Dakota's only operating gold mine is the Wharf mine at Lead, a Coeur Mining open pit heap leach operation that produced 109,000 ounces of gold in 2016. Tennessee. In 1827, on Coker Creek in Monroe County, Tennessee, Placer gold was discovered. Some 9,000 troy ounces (280 kg) were produced by the district.
The White Dam Gold Operation is a heap leach project and since, 2010 has produced approximately 175,000 oz gold from heap leaching of ~7.5 Mt of ore which has been mined from two open pits. Available reconciliation of mining against resource estimates is good and indicates that a significant tonnage of mineralised material remains to be mined
Öksüt was planned as a conventional truck and shovel open pit heap leach mining operation with a stacking rate of 11,000 tonnes per day. The initial eight-year mine life was expected to process approximately 1.2 million contained ounces of gold from two open pits, the Keltepe pit and the smaller Güneytepe pit.

Dec 31, 2019· The Moss Mine is an open pit gold-silver operation, with a favorable strip ratio of approximately 1.85:1 (waste to ore) and minimal haul distances to the crushing plant. The most economic and effective way to process the ore is through crushing, agglomeration and heap leaching followed by processing at the on-site Merrill Crowe metal recovery

Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined. Heap Leaching
Equinox Gold's Mesquite Mine in California is an open-pit heap leach mine that has been in production since 1985. The Company's Castle Mountain Phase 1 Mine in California commenced operations in September, with first gold pour targeted for Q4-2020.
The primary mining option for this ore deposit was for underground mining, because the ore area lies at a depth over 430 m, therefore an open pit option was completely ruled out, considering the high ore waste rates which this type of mining would imply.

The Mulatos mine is a conventional open-pit, heap-leach operation with gold recovered through a carbon-in-column circuit. Ore is sourced from a number of open pits within the Mulatos District providing stable low-cost gold production. These include the main Mulatos and Cerro Pelon open pits as well as existing stockpiles.
Oct 26, 2020· The Gold Bar project is an open-pit heap leach operation owned by McEwen Mining (MMI). Located in Eureka County, Central Nevada, US, the mine is situated within the Battle Mountain-Eureka-Cortez gold trend. It is located approximately 25 miles (40.2km) away from Waterton Global's Ruby Hill Mine and 35 miles (56.3km) from Barrick's Cortez Mine.
Dec 24, 2018· Barrick Nevada's Cortez property is still going, with ore drawn from the Pipeline complex open pit, and Cortez Hills, a combination underground/ open pit mine. Heap leaching technology was a major breakthrough because it significantly reduced gold recovery costs (versus traditional cyanide leaching - see section below on gold recovery costs
