Arizona Sonoran Appoints Minviro to Complete Carbon Emissions Framework Review

CASA GRANDE, Ariz. & TORONTO–(BUSINESS WIRE)–$ASCU #ESG—Arizona Sonoran Copper Company Inc. (TSX:ASCU) (�ASCU” or the “Company”), an emerging US-based copper developer and near-term producer, has engaged London-based Minviro Ltd. to review its carbon emissions framework and determine the best path towards establishing a net-zero CO₂ operation at the Cactus Project.

The Minviro-led Life Cycle Assessment (LCA) will enable ASCU to clearly and robustly quantify the life cycle impact of mining, processing and refining options and solutions, and detailed environmental impacts of the operation.

In conjunction with the launch of this review, the Compensation Committee of the Company and Board has also established specific ESG criteria linked key performance indicators in respect of management compensation. Full details of these key performance indicators will be made available in the Company’s management information circular in 2022.

George Ogilvie, Arizona Sonoran President and CEO commented, “Being proactive about managing our impacts and achieving a net zero operation is at the core of ASCU’s corporate and ESG strategy. The launch of the partnership with Minviro will assist our carbon conscious management team to ensure minimal carbon emissions from our operations in the medium-long term and manage our supply chain effectively to support the goals set by the Paris Agreement. As we advance through our pre-feasibility and feasibility studies, the LCA will provide us with high-quality operating data which we will integrate into our technical studies, targeted towards the achievement of our net zero goal in the long term. Incorporating ESG criteria into management compensation KPIs further aligns our interests with those of our stakeholders and we look forward to updating all stakeholders in due course regarding this exciting initiative.”

Key components of the LCA to be based on the Integrated Cactus PEA include:

• the determination of ASCU’s baseline carbon footprint;
• identifying scope 1 and 2 upstream and downstream emissions;
• identifying scope 3 emissions generated by potential materials consumed at site and in the production of copper cathode product;
• LCA inventory data for copper cathode production process; and
• assessment of climate change impact.

Once the baseline product carbon footprint is determined, the environmental and economic value proposition of CO₂ mitigation and minimum impact scenarios will be investigated. The goal of the assessment is to develop a framework which feeds into ASCU’s PFS and DFS to provide a pathway to net zero operations at the Cactus Project.
