Alta Copper Corp. Receives Drill Permit Application from Ministry of Energy and Mines of Peru Alta Copper Corp. announced that its Declaracion de Impacto Ambiental drill permit application has been approved by the Ministry of Energy and Mines of Peru ("MINEM") while also receiving Certificates of Non-Existence of Archaeological Remains on Surface ("CIRAS") from the Ministry of Culture of Peru. The Company submitted its DIA to MINEM in December 2023 which included advanced Environmental and Social Impact Assessment studies ("ESIA"). As previously reported the DIA process included a successful community participation workshop held in late October 2023 during which the Executive Management of Energy and Mines for the Regional Government of Lambayeque explained the scope of the environmental studies and the DIA application to the community of Canaris. The DIA determines the environmental viability to drill 42,400 meters to be completed in phases of 10,000 meters which is targeted to commence prior to second quarter-2025. As required pursuant to the National Environmental Impact Assessment System Law approved by Law Ndeg 27446, its regulation and the Environmental Protection Regulations for Mining Exploration Activities approved by Supreme Decree Ndeg 042-2017-EM, Alta Copper was required to file an ESIA and obtain an Environmental Management Instrument. The Environmental Management Instrument to conduct mining exploration activities was required in view of the advanced stage of development of the Canariaco project. In anticipation of the Company's drilling program Alta Copper completed a new geological model for the Canariaco Norte deposit in 2024 while identifying significant mineralization potential and numerous high priority drill targets which will provide the foundation for future drilling programs. The DIA will allow for up to 42,400 metres of drilling to be completed in phases of10,000 meters. The proposed drill holes have been targeted to cross and fill in the recently identified zones of high-grade copper mineralization extending to depth in Canariaco Norte which are not included in the current mineral resource estimate due to drill spacing between the holes and limitations of drill data at depth. The remaining drill platforms will be used to drill the Canariaco Sur and Quebrada Verde porphyries, targeting extensions of known mineralization laterally and at depth and near surface geochemical anomalies and mineralization exposed in creek beds. Geological Modelling completed in 2024 included the re-interpretation of district-scale and project-specific geology including statistical analyses on alteration effects to various lithologies. The 2024 geological modelling identified several high-grade copper zones with previously untested potential depth extensions. These zones as well as internal zones, where infill drilling could expand some high-grade zones, will be drill tested with the goal of further enhancing the current substantial mineral resource already defined at Canariaco. The 2024 geological model for alteration and lithologies relies on detailed logging of 85,000 metres drilled between 2004 and 2013, largely in Canariaco Norte. Information which was captured in historic logs has been recently reviewed. Multi-element geochemical data available for most of the holes was used to establish lithological and alteration zonation modelling. The data collected has not previously been incorporated into a formal three-dimensional geological model. It is expected that future drilling of defined high priority targets is expected to improve project economics recently reported in the Company's Preliminary Economic Assessment completed in May 2024. Further drilling and resource expansions will be considered as the project continues along the development and permitting path. A review of deeper zones of the Norte deposit recently identified that 32 of 47 drill holes drilled to 400 metres or more bottomed in mineralization. DDH 07-135 bottomed in 0.55% Cu (over last 10 metres) at 721 metres. Announcement • Sep 17

Alta Copper Corp. Provides an Update on Significant Developments and Progress to Date on Several Fronts At Its 100% Owned Cañariaco Advanced Staged Copper Project Alta Copper Corp. provided an update on significant developments and progress to date on several fronts at its 100% owned Canariaco advanced staged copper project. Whittle Consulting Pty Ltd. ("Whittle") and Ausenco Engineering Canada Inc. ("Ausenco") and AGP Mining Consultants Inc. were engaged in 2023 for purposes of advancing project optimization which involves a rigorous analytical and computational process using Whittle's Strategic Mine Planning software and Integrated Strategic Planning concepts. To date, hundreds of iterations of pit shells have been conducted to establish the most advantageous mine plan. In addition, statistical studies that identified several compelling alteration effects on the deposit, were incorporated into 3D Geological Modelling and have been linked to zones with higher copper grades all of which will be incorporated in Optimized PEA. Based on what are considered very positive developments with 3D Geological Modelling, more fully described below, positive metallurgical testwork on Cañariaco Sur and Whittle optimization, the Company is now targeting to publish the optimized 2024 PEA on or before May 15, 2024. The Optimized PEA has benefited from previously conducted engineering studies over many years, especially 2010 through 2014 and 2021 to 2022, which will prove to show many aspects developed beyond a typical PEA level. A new geological model for the Project has been completed with the re-interpretation of district-scale and project-specific geology including statistical analyses on alteration effects to various lithologies. This new geological model, has identified significant mineralization potential and numerous high priority drill targets which will provide the foundation for the planned staged 10,000 to 20,000 metre drilling program targeted to commence by Q4-2024. The 2024 geological modelling has identified several high-grade copper zones with previously untested potential depth extensions. These zones as well as internal zones, where infill drilling could expand some high-grade zones, will be drill tested with the goal of further enhancing the current substantial mineral resource already defined at Cañariaco. The 2024 geological model for alteration and lithologies relies on detailed logging of 85,000 metres drilled between 2006 and 2013, largely in Cañariaco Norte. Information which was captured in historic logs has been recently reviewed. Multi-element geochemical data available for most of the holes was used to establish lithological and alteration zonation modelling. The data collected has not previously been incorporated into a formal three-dimensional geological model. Interpretation of geology was hand drawn on cross sections, where appropriate, and together with the other technical datasets, was integrated into Leapfrog software to generate the new three-dimensional model. Current geological model and observations from historical drilling will provide the framework for upcoming diamond drilling program. In addition, a generative study is underway to provide a portfolio of targets for future testing, in a district that remains underexplored. Announcement • Apr 13
