Frederick Bell, CEO of Elemental Altus, commented: 'We are very pleased to increase our royalty exposure to the Caserones copper mine in Chile following the Lundin Mining announcement to acquire majority ownership. The mine continues to be a cornerstone revenue generating asset in our portfolio and we believe there is significant exploration potential to be unlocked in the district, as highlighted by NGEX Minerals' exploration results immediately to the south.'

Terms of the Acquisition

The Caserones mine is subject to a 2.88% NSR royalty created in a 2009 agreement between SCM Minera Lumina Copper Chile S.A., as purchaser, and Compania Minera Caserones ('CMC') and Sociedad Legal Minera California Una de la Sierra Pena Negra ('SLM California'), as vendors. CMC and SLM California originally held the mineral concessions that cover the Caserones deposit. Ownership of the 2.88% NSR royalty is currently divided between CMC (32.5%) and SLM California (67.5%).

Elemental Altus has agreed to purchase an additional 1.56 new shares in SLM California for a total cash consideration of US$2,598,802. The acquisition is in addition to the purchase of 1.29 shares announced on March 9, 2023 and increases the shareholding of the Company in SLM California to 24.35%. The Company's effective NSR interest in Caserones has increased by 0.030% to 0.473%.

Caserones Mine Overview

The Caserones mine is a large, open-pit porphyry copper-molybdenum deposit, located within a 170km2 land package at an elevation of approximately 4,300m above sea level in the borough of Tierra Amarilla, in the Atacama region of northern Chile. The mine is approximately 15km from the border with Argentina, 162km southeast of the city of Copiapo and 800km north of the capital, Santiago.

Located at the southern end of the well-documented Maricunga mineral belt, the geology of Caserones comprises an Early-Miocene porphyry system associated with a cluster of dacite porphyries and breccias intruding Palaeozoic granitic, volcanic, and metamorphic rocks. Caserones has a well-developed supergene enrichment profile of oxide copper and secondary chalcocite that overlies hypogene sulfide (chalcopyrite-molybdenite) mineralisation. The mine produces copper and molybdenum concentrates from a conventional crusher, mill and flotation plant, as well as copper cathodes from a dump leach, solvent extraction and electrowinning plant and has been in operation since 2014.
