Arizona Sonoran Granted Amended Industrial Air Permit and Completes Local Polling with 87% Support for the Cactus Project

Arizona Sonoran Copper Company Inc. (TSX:ASCU | OTCQX:ASCUF) ("ASCU” or the "Company”) an emerging US-based copper developer, is pleased to announce an amendment to the Industrial Air Permit has been received from the Pinal County Air Quality Division. The amended Aquifer Protection permit has been applied for and is currently under review by the Arizona Department of Environment and Quality, ADEQ.

The amended Industrial Air permit pertains to a February 2024 Pre-Feasibility Study ("2024 PFS”) configuration, which excluded the MainSpring deposit. A subsequent Preliminary Economic Assessment ("2024 PEA”), incorporating MainSpring, was issued in August 2024 and supersedes the 2024 PFS. The 2024 PEA contemplates an operation expected to produce 116,000 short tons of copper cathode per year over the first 20 years of a 31-year mine life.

Through regular communication and involvement within the community, the Company’s transparent approach has contributed to permitting success. Additionally, as part of the continuing community engagement strategy, the Company recently completed an updated polling survey demonstrating support for the Cactus Project of 87% within Casa Grande and surrounding areas.

ASCU President and CEO, George Ogilvie commented, "The issuance of the amended Industrial Air permit is yet another key milestone in the advancement of Cactus, a standalone operation requiring only permits from the State and local government as the Cactus Project sits entirely on private land with no Federal permitting nexus. Cactus is a standout lower risk copper asset based on its tier 1 location, the permitting process, onsite infrastructure, including rail, road, power and water, the sizeable copper resource estimate, associated mine plan, related economics and first quartile capital intensity. Our team has done a tremendous job advancing the asset and navigating the streamlined State-led permitting process. We look forward to continuing to advance towards PFS in H2 2025, and subsequently submitting final amendments ahead of a final Definitive Feasibility Study ("DFS”) in 2026, project financing, and the construction and development decision. Additionally, we would like to thank Pinal County Air Quality Division, and the local communities for their ongoing support for the Cactus Project.”

LOCAL POLLING

In October, the Company commissioned a poll of 500 frequent voters in Casa Grande and surrounding areas, based on the 2024 PEA mine plan. Polling determined that 86.6% of the survey respondents supported the Cactus Project, up from 82.6% in 2021. Notably, Republicans, Democrats, Independents and others, indicated a range of support from 76.1% to 93.2%, with an uptick in Democratic support from 67.1% to 76.1%; a testament to the Company’s consistent and proactive approach to being a good neighbor. The positive polling numbers indicate overwhelming support from the community and an affirmation of strong ASCU’s social license.

Travis Snider, ASCU VP Sustainability and External Relations, commented, "Given the recent issuance of the 2024 PEA detailing copper cathode production of 116,000 short tons per annum ("stpa”) over the first 21 years of a 31-year mine life predominantly via open-pit mining, it was important to gauge the local communities support for this larger and generational mine plan. Therefore, the updated Perception Survey was undertaken two months following the release of the 2024 PEA, allowing prior dissemination of the results into the community. The results showed continued strong support for the Project, and, specifically, an increase in support to restart production at the Project. This is a testament to the great work our Project team is doing in Casa Grande and surrounding areas, in keeping the local community informed of our business plans.”

PERMITTING BACKGROUND

Following the Initial Public Offering in late-2021, the Company received its initial Industrial Air and Aquifer Protection and Mined Land Reclamation Permits, for a Mine Plan envisaging 28,000 stpa of copper cathode with an 18-year Mine Life, in 2023. Three years later, the scale of the deposit and conceptual production profile grew in the 2024 PFS, largely due to the discovery of the Parks/Salyer deposit. Being awarded an amended Industrial Air Permit pertaining to the 2024 PFS, which contemplated 55,000 stpa of copper cathode production with a 21-year mine life, within 4 months of having the application administratively accepted is another positive step forward. Although the permit is not for a final mine plan related to a construction and development decision, it is a positive affirmation that being on private land presents a significantly more efficient State permitting regime.

The recent growth reflected in the 2024 mineral resource estimate and Project expansion in the 2024 PEA was largely due to the acquisition of the MainSpring property with near surface mineralization, and ultimate rescoping of Parks/Salyer to an open pit from underground mining. Building off the 2024 PEA, a standalone Cactus PFS is expected to be issued in H2 2025, based on which the Company intends to re-apply for amended permits that should be well in hand ahead of a standalone DFS, planned for delivery in 2026. Assuming the final DFS has robust project economics, and project financing has been secured, the Project would also be fully-permitted for a construction and development decision at that time.

Preliminary Economic Assessments

The 2024 Preliminary Economic Assessment (or 2024 PEA) referenced in this press release and summarized in the 2024 PEA Technical Report is only a conceptual study of the potential viability of the Cactus Copper Project and the economic and technical viability of the Project has not been demonstrated. The 2024 PEA is preliminary in nature and provides only an initial, high-level review of the Project’s potential and design options; there is no certainty that the 2024 PEA will be realized. For further detail on the Project and the 2024 PEA, including applicable technical notes and cautionary statements, please refer to the Company’s press release dated August 7, 2024 and the 2024 PEA Technical Report, both available on the Company’s website at www.arizonasonoran.com and under its issuer profile at www.sedarplus.ca.

Mineral Resource Estimates

Until mineral deposits are actually mined and processed, copper and other mineral resources must be considered as estimates only. Mineral resource estimates that are not classified as mineral reserves do not have demonstrated economic viability. The estimation of mineral resources is inherently uncertain, involves subjective judgement about many relevant factors and may be materially affected by, among other things, environmental, permitting, legal, title, taxation, socio-political, marketing, or other known and unknown risks, uncertainties, contingencies and other factors described in the foregoing Cautionary Statements on Forward-Looking Statements. The quantity and grade of reported "inferred” mineral resource estimates are uncertain in nature and there has been insufficient exploration to define "inferred” mineral resource estimates as an "indicated” or "measured” mineral resource and it is uncertain if further exploration will result in upgrading "inferred” mineral resource estimates to an "indicated” or "measured” mineral resource category. Inferred mineral resource estimates may not form the basis of feasibility or pre-feasibility studies or economic studies except for preliminary economic assessments. The accuracy of any mineral resource estimate is a function of the quantity and quality of available data, and of the assumptions made and judgments used in engineering and geological interpretation, which may prove to be unreliable and depend, to a certain extent, upon the analysis of drilling results and statistical inferences that may ultimately prove to be inaccurate. It cannot be assumed that all or any part of a "inferred”, "indicated” or "measured” mineral resource estimate will ever be upgraded to a higher category including a mineral reserve. The mineral resource estimates declared by the Company were estimated, categorized and reported using standards and definitions in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards for Mineral Resources and Mineral Reserves (the "CIM Standards”) in accordance with National Instrument 43-101 of the Canadian Securities Administrators ("NI 43-101”), which governs the public disclosure of scientific and technical information concerning mineral projects.

U.S. Readers

The terms "mineral resource”, "measured mineral resource”, "indicated mineral resource” and "inferred mineral resource” as disclosed by the Company are Canadian mining terms defined in the CIM Standards (collectively, the "CIM Definitions”) in accordance with NI 43-101. NI 43-101 establishes standards for all public disclosure that a Canadian issuer makes of scientific and technical information concerning mineral projects. These Canadian standards differ from the requirements of the United States Securities and Exchange Commission (the "SEC”) applicable to United States domestic and certain foreign reporting companies under Subpart 1300 of Regulation S-K ("S-K 1300”). Accordingly, information describing mineral resource estimates for the Cactus Copper Project may not be comparable to similar information publicly reported in accordance with the applicable requirements of the SEC, and so there can be no assurance that any mineral resource estimate for the Project would be the same had the estimates been prepared per the SEC’s reporting and disclosure requirements under applicable United States federal securities laws, and the rules and regulations thereunder, including but not limited to S-K 1300. Further, there is no assurance that any mineral resource or mineral reserve estimate that the Company may report under NI 43-101 would be the same had the Company prepared such estimates under S-K 1300.
