The Tambo de Oro is an underground gold mine located in Coquimbo Region in north-central Chile. More precisely it lies near the Pacific in the commune of Punitaqui in the mining district of Punitaqui. The mine is operated by HMC Gold, a subsidiary of Haldeman Mining. In December 2021 the mine obtained permission from the Environmental Assessment Service to extend its operations for seven more years.[1] In addition, the mine was allowed in increase its monthly average production from 15,000 to 15,317 metric tons.[1] The mine has been required to install private security system after it was declared a "strategic enterprize" by the Ministry of the Interior in November 2023.[2] Haldeman Mining has disputed this designation in courts.[2]
In September 2020 two miners died as result of a rockfall in the mine.[3]
The mine produces gold ore concentrate from ores in the form of veins and breccias of Early Cretaceous age.[2][4] The ores have characteristics that are both epithermal and mesothermal.[4]
