The concentration of property to establish a large mine begun 1975 when [[Augusto Pinochet]] gave permission to [[ENAMI (Chile)|ENAMI]] to purchase surface real estate from the inhabitants of Andacollo.{{sfn|Danús|2007|p=187}} Businessman [[Andrónico Luksic Abaroa|Andrónico Luksic]] resisted the purchase of his property and he eventually acceded for a swap for a mining property in [[Los Pelambres]].{{sfn|Danús|2007|p=188}} The mine property was put to into an international tender for a company willing to form a joint venture with ENAMI.{{sfn|Danús|2007|p=188}} [[Noranda Mines]] showed some interest but ultimately declined. A tender in 1990 ended in a similar maner with [[Placer Dome]] showing interest before declining.{{sfn|Danús|2007|p=188}} In 1994 after a new tender a joint venture of [[Carbon Tungsten]] and [[Compañía Minera del Pacífico]] (CMP) accepted the conditions of ENAMI, beginning the modern mine.{{sfn|Danús|2007|p=189}} At this point the ownership of the mining company Compañía Minera Carmen de Andacollo was as follows; Carbon Tungsten (63%), CMP (27%) and ENAMI (10%), with CMP itself being a joint-venture of steelmaking [[CAP S.A.|CAP]] and ENAMI.{{sfn|Danús|2007|p=189}}<ref name=reuter/> Production begun in 1994.<ref name=intmin/>
Soon, 63% of shares passed from Carbon Tungsten to [[Aur Resources]], which years later in late 2006 increased its shares to 90% after purchasing them from CMP.<ref>{{Cite news |title=Aur Resources compra 27% de CMP en Carmen de Andacollo |date=2006-12-06 |url=https://www.mch.cl/negocios-industria/aur-resources-compra-27-de-cmp-en-carmen-de-andacollo/ |access-date=2025-07-30 |work=Minerería Chilena |language=es}}</ref><ref name=reuter>{{Cite news |title=Canada's Aur agrees to boost stake in Andacollo mine |last= |date=2007-08-09 |url=https://www.reuters.com/article/legal/government/canadas-aur-agrees-to-boost-stake-in-andacollo-mine-idUSN06384696/ |access-date=2025-07-30 |work=Reuters}}</ref> In 2007 Aur Resources was purchased by [[Teck Cominco]].{{sfn|Danús|2007|p=189}}<ref name=intmin>{{Cite news |title=Teck Cominco successfully acquires Aur Resources |date=2007-08-23 |url=https://im-mining.com/2007/08/23/teck-cominco-successfully-acquires-aur-resources/ |access-date=2025-07-30 |work=International Mining}}</ref>
