Nittetsu Mining Co., Ltd. entered into an agreement, dated April 20, 2026, with Eagle Mountain Mining to participate in the Oracle Ridge Project, a copper exploration venture located in the State of Arizona, U.S.A. The Project is located approximately 40 km northeast of Tucson, the second-largest city in the State of Arizona, U.S.A. Under this agreement, a total of USD 20 million will be invested in the Project over four years to obtain environmental permits, conduct drilling exploration, and carry out a feasibility assessment. Upon payment of the initial expenditure at the time of contract signing, the equity interests in the joint venture company will be held 80% by Nittetsu and 20% by EM2. In addition, Nittetsu will hold 100% offtake rights (product purchase rights) for the Project. Nittetsu believes that the Project is of a scale well-suited to the Company's financial capacity and development capabilities, and that the Company can leverage its track record and experience in Chile — including over 20 years of copper concentrate production at the Atacama Mine and the development of the Arqueros Mine, scheduled to commence operations in 2026. The establishment of a presence in the United States is also seen as contributing to the growth of the Company's metal resources business by diversifying away from concentration risk in Chile.

Camino Minerals Corporation announced that its joint venture with Nittetsu Mining Co. Ltd. will initiate leaching studies at Nittetsu's metallurgical and chemical facility in Tokyo. These studies aim to assess the scalability of the Puquios Copper Project. The Puquios mine is planned as a conventional sulphide leaching operation utilizing solvent extraction and electro winning technology. All permits required for commencement of construction are in place, with mine construction anticipated in the first half of 2026. To support development, Camino and Nittetsu are actively pursuing a debt facility with a Japanese lender that is expected to offer highly competitive terms in the current mining finance environment. The first stage of the Puquios copper mine development is now on a path towards production. The Company is evaluating scale-up opportunities targeting the hypogene copper mineralization located beneath the supergene, soluble copper zones. The Project has approximately 8,170 metres of drilling completed in the primary mineralized zone. Two exploration adits have been developed to reach the copper mineralization at depth and samples of the deeper mineralization have been extracted and delivered to Nittetsu's research and development facility in Tokyo for testing. Nittetsu has been advancing proprietary copper extraction technologies and initial results demonstrate competitive recoveries for different types of copper mineralization. The deeper copper mineralization at Puquios will be leached at the facility, for further consideration for the next phase of the Project's scale-up. Looking ahead, the Company intends to further assess and integrate new leaching technologies to determine the most effective scale-up strategy for expanding copper production at Puquios.
