Asset Portfolio


The Caserones open pit mine is developed on a porphyry copper-molybdenum deposit in the Atacama Region of the northern Chilean Andean Cordillera.  The mine has been in operation since 2014, and is owned and operated by SCM Minera Lumina Copper Chile SpA, which is indirectly 100% owned by JX Nippon Mining & Metals Corporation of Japan. EMX has an effective 0.7335% NSR royalty on Caserones and is receiving quarterly payments from the operation.

The mine produces copper and molybdenum concentrates from a conventional crusher, mill and flotation plant, as well as copper cathode from a dump leach, solvent extraction and electrowinning plant. In 2021 the mine produced 94,846 tonnes of fine copper in concentrate, 2,287 tonnes of fine molybdenum in concentrate, and 14,829 tonnes of fine copper in cathodes (see Lumina’s 2021 Annual Report dated May 30, 2022).

Caserones is located at the southern end of the Maricunga mineral belt and occurs as an Early-Miocene porphyry system. The deposit has a well-developed supergene enrichment profile of oxide copper and secondary chalcocite that overlies hypogene sulfide (chalcopyrite-molybdenite) mineralization. In addition to currently defined zones of mineralization, considerable upside exists on the Caserones property, and exploration for additional resources and reserves has been ongoing.

EMX has filed a Technical Report titled “NI 43-101 Technical Report, Caserones Copper-Molybdenum Mine Royalty, Region III, Chile” with an effective date of February 28, 2022 and report date of March 1, 2022. The Technical Report was prepared by Gregory W. Walker, Independent Consulting Geologist, SME RM, and has been filed on SEDAR under the Company’s profile.
