EMX Royalty Corporation (NYSE: EMX) (TSX-V: EMX)  is pleased to announce the acquisition of a 1.25% NSR royalty over the Puquios development stage copper project in north central Chile, located near the city of La Serena. The Puquios project is owned by Cuprum Resources Chile SpA, an operating company jointly owned by Camino Minerals Corp. (TSX-V: COR)  and Nittetsu Mining Co., Ltd of Japan. EMX purchased the Royalty from Santiago Metals Upper Holdco LLC, a company owned by a fund advised by Denham Capital Management LP, which owned and operated the project prior to its sale to Camino and Nittetsu. Camino and Nittetsu each have skilled and experienced mine development teams, and Denham has also financed the construction and operation of numerous mining operations in Chile and elsewhere in the world. Nittetsu has notably operated in partnership with Inversiones Errazuriz to construct and operate the Atacama Kozan (Los Bronces) copper-gold mine in central Chile and is currently constructing the Arqueros copper mine in the La Serena region.

The Puquios project is a supergene copper deposit in the foothills of the Andean mountain range and overlies a partially explored porphyry copper-molybdenum deposit. The current Proven and Probable reserves for the supergene Puquios deposit are 26.0 Mt averaging 0.494% copper¹. A Prefeasibility Study for the project was published in March 2025, and shows robust economics for the project, including projected production of 223 million pounds of copper over a 14.2 year mine life (see Camino News Release dated March 17, 2025). Cuprum has obtained the necessary permits to commence construction of the project (including water rights) and Camino and Nittetsu are currently arranging project financing. Camino has provided a recent project update, highlighting the scalability of the project and its development status (see Camino News Release dated Oct 30, 2025).

The supergene copper deposit is located within a hilltop overlying a more extensive primary porphyry copper deposit that has only seen limited drilling. The underlying porphyry deposit remains open in multiple directions and at depth. Additionally, Puquios is positioned within a more extensive belt of hydrothermal alteration and copper and gold occurrences with numerous areas of historic mining and exploration. This belt extends for at least 8 km east to west within the Royalty footprint. The underlying porphyry copper-molybdenum deposit and extensive mineralization trend at Puquios provide EMX with considerable exploration upside and discovery optionality. Camino and Nittetsu are also evaluating the potential for new leach technologies to beneficiate the underlying sulfide copper mineralization, with Nittetsu’s technology demonstrating promising sulphide leaching results (also discussed in the Camino News Release dated Oct 30, 2025).

Commercial terms. EMX has paid Denham USD $6 million in exchange for the Royalty, with another USD $2 million payment due upon the commencement of construction of Puquios. Further, EMX has subscribed to a concurrent financing, where Camino is arranging a non-brokered private placement to raise total gross proceeds of CAD $5.5M for the advancement of Puquios through project financing and a final investment decision. EMX has subscribed to CAD $2.5 million of the financing for approximately 6.94 million shares at CAD $0.36 per share. EMX’s position in Camino provides exposure to Camino’s other exploration projects in Chile and Peru, notably including the Los Chapitos IOCG copper and gold project in Peru, also being explored in cooperation with Nittetsu.

¹Notes on Mineral Reserves. The Mineral Reserves estimates for Puquios were reported in Camino News Release dated March 17, 2025 and were prepared by Jesse Aarsen, P.Eng. (who is also an Independent Qualified Person) using the 2014 CIM Definition Standards and have an effective date of September 21, 2021. The cut-off grade used for ore/waste determination is NSR >= US$5.59/t. Cut-off grade assumes US$3.19 /lb Cu, block recoveries from the block model, US$75/t cathode premium, 2% vendor royalty and US$0.30/lb SX/EW costs. The average associated metallurgical recovery for copper was modelled at 79%. Mineral Reserves were converted from Measured and Indicated Mineral Resources through the process of pit optimization, pit design, production schedule and are supported by a positive cash flow model. The Mineral Reserves reported are the tonnages delivered to the crusher, pre-delivery to the heap leach pad. Rounding as required by reporting guidelines may result in summation differences. Further information and details are available in the Puquios Project Technical Report entitled “Puquios Project – NI 43-101 Technical Report and Pre-feasibility Study, La Higuera, Coquimbo Region, Chile”, with an effective date of January 24, 2025, which is available on SEDAR+ under Camino’s filings. EMX has not performed sufficient work to verify the published data reported above, but EMX believes this information to be reliable and relevant.
