Caserones
copper mine in Chile
Caserones is a low-grade copper and molybdenum mine in Tierra Amarilla in Atacama Region, Chile. The mine is operated by SCM Minera Lumina Copper Chile, a joint venture where Lundin Mining have 70% of the shares and JX Nippon Mining & Metals owns the remaining. The mine lies about 4,000 m a.s.l. in the Andes and just about six kilometers west of the Argentina–Chile border.
Construction of the mine started in 2010 and it began operations in 2014. Mining is expected to last until 2042 according to the mining plan. An environmental impact assessment to modify the previously approved mining project was submitted in 2020 and approved by authorities in July 2025. In January 2026 SCM Minera Lumina Copper submitted a plan to the Environmental Assessment Service to extend the mine lifetime to 2039.
Originally, JX Nippon Mining & Metals owned 51.5% of the mine and Mitsui Mining and Smelting owned 25.87% and Mitsui & Co. 22.63%.

Why this record matters
The phrase “copper mine in Chile” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 3, 2026. The linked authority identifier is Q19951135. Authority coordinates are -28.167, -69.544. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2010, 2014, 2042 and 2020.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
