Cactus Project: Prefeasibility Study Results and Future Outlook

Arizona Sonoran Copper's CEO, George Ogy, provided an update on the company's Cactus Project in Arizona, highlighting exceptional results from the recently released Prefeasibility Study (PFS). The project is positioned as a domestic source of copper for the United States, with no tariffs involved.

Financial and Economic Highlights

• Copper Price Assumption: The financial and economic model was based on a conservative flat copper price of $4.25 per pound, significantly below current consensus and spot prices.
• Net Present Value (NPV): The project boasts an after-tax NPV of $2.3 billion, calculated using an 8% discount factor.
• Internal Rate of Return (IRR): The after-tax IRR stands at an impressive 22.8%.
• Upfront Capital: The initial capital expenditure is estimated at $977 million, including contingency.
• Capital Intensity: This translates to a capital intensity of approximately $10,900 per tonne.
• Free Cash Flow: Over the life of the mine, at $4.25 per pound copper, the project is projected to generate over $7 billion in unlevered, after-tax free cash flow.

Operating Costs and Production

• All-in Sustaining Cost (AISC): The AISC is projected at a remarkably low $2.00 per pound, which is considered exceptional given the project's location in the US with higher labor costs.
• Cost Drivers: The low operating costs are attributed to the project's nature as a large, open-pit porphyry copper deposit, benefiting from economies of scale.
• Material Handling: A significant portion (60%) of the material to be moved is alluvium and conglomerate, which is "free dig" and does not require drilling and blasting. A continuous miner test achieved a rate of 3,500 tonnes per hour for this material. While deeper sections and the ore itself will require drilling and blasting, the free-dig material significantly reduces operating costs.
• Annual Production: The project is estimated to produce an average of 103,000 tonnes of copper cathode annually for the first 10 years, positioning it as a mid-tier producer.

Permitting and Project Timeline

• Permitting Process: With the PFS public, Arizona Sonoran Copper is in the process of applying for amendments to existing permits. As the project is on private land with no federal nexus, a streamlined process is anticipated.
• Timeline: Applications are being submitted in November, with an expectation of administrative acceptance within two months. Final amended permits are anticipated by June or July of the following year, allowing for construction and development.
• Bankable Feasibility Study (BFS): The BFS is expected to be released in the third quarter of the following year, coinciding with the announcement of project financing, particularly the debt component through commitment letters.

Reserves and Future Exploration Potential

• Current Reserves: The company has 5.3 billion pounds of copper in reserves.
• Total Mineral Resource: The updated mineral resource estimate stands at 11 billion pounds of contained copper.
• Mine Life: The current plan focuses on two open pits (Park Siffler and a layback of Cactus West), providing a 20-year mine life, with the last two years involving residual copper recovery from leach pads.
• Future Opportunities: The current plan excludes primary sulfides (which could be processed via flotation or other technologies) and Cactus East (a historical underground mine). These represent significant future opportunities.
• Exploration Upside: Historical drilling by ASARCO 40 years ago encountered mineralization, and exploration drilling was paused 18 months prior due to market conditions and a focus on the PFS. Future exploration is expected to add to the resource base.
• Extended Mine Life: With the inclusion of Cactus East and potential future exploration success, the mine life could extend to 30-40 years, with an average annual production of around 100,000 tonnes of copper cathode.

Technological Advancements and Energy Costs

• Metallurgy: The company believes they are at an optimal level for metallurgy.
• Fleet Electrification: While the current plan utilizes traditional diesel-powered 320-tonne rigid frame trucks, there is potential for future conversion to battery or trolley-powered electric trucks.
• Green Energy Access: The project benefits from access to abundant and affordable electricity, with the main transmission line from the Palo Verde nuclear reactor passing through the property.
• Power Costs: Power costs are estimated at a competitive 6 cents per kilowatt-hour, with a conservative projection of 7.5 to 12 cents per kilowatt-hour as production ramps up. This is significantly advantageous compared to other jurisdictions.

Royalties and Shareholder Value

• Net Smelter Returns (NSR): The project has two or three NSR royalties, with a 2.54% NSR already incorporated into the economic model.
• Royalty Buy-back: Arizona Sonoran Copper recently bought back 64% of its NSR from Royal Gold and Elemental Altus for $8.9 million. This buy-back is accretive to shareholders, retaining significant cash flow within the company that would have otherwise gone to royalty holders. The CEO estimates this could save shareholders hundreds of millions of dollars if copper prices rise as predicted.

Financing and Capital Structure

• Debt-to-Equity Ratio: The company is stress-testing the model down to a copper price of $3.75 per pound. At this price, they anticipate a debt-to-equity ratio of 55-60% debt and 40-45% equity. Higher copper prices would allow for increased leverage, minimizing equity dilution and improving Net Asset Value (NAV) per share.
• Royalty Stance: The company is not in favor of issuing further royalties, preferring to retain upside for shareholders.
• Byproduct Credits: While primarily a copper producer, the deposit contains minor amounts of gold, silver, and molybdenum. If the company were to revert to flotation processing for primary sulfides beyond year 20, these byproducts could provide additional revenue streams, particularly molybdenum, which is crucial for magnets and rare earths.

Financial Position and Funding

• Cash Reserves: As of the end of July, the company had $58 million in cash.
• Funding Horizon: The company is fully funded through the fourth quarter of 2026, which will see the BFS released, project financing in place, and final permits secured. This ensures the company is funded to a Final Investment Decision (FID).

Shareholder Protection and Takeover Defense

• Shareholder Registry: Key shareholders include Hubby (10%), management (4%), and another large shareholder (13%), totaling 27%. This stake provides a blocking position against unfriendly takeovers.
• Poison Pill: A poison pill was implemented last year and unanimously approved by shareholders in June of the current year to protect against creeping takeovers.

Copper Market Outlook

• Bullish Sentiment: George Ogy expresses a very bullish outlook on copper, driven by supply and demand fundamentals.
• Supply Constraints: Current high copper prices are attributed to significant supply constraints, including technical challenges at major mines and the increasing difficulty of accessing deeper, higher-grade deposits. Further supply constraints are anticipated.
• Demand Growth: While current economies are sluggish, a return to pre-COVID GDP growth levels in the Northern Hemisphere would lead to exponential demand growth, which the current supply cannot meet.
• Incentive Price: To incentivize new copper supply, which takes decades to bring online, the incentive price needs to be significantly higher than current spot prices, requiring IRRs of 20%+ for mining companies.
• Comparison to Uranium: The situation is compared to the uranium market, where increasing demand for nuclear energy is met with insufficient supply.
• US Copper Deficit: The US currently imports approximately 600,000 tonnes of refined copper annually to meet its demand of 1.4 million tonnes, highlighting the strategic importance of domestic copper production.

Project Location and Logistics

• Strategic Location: Situated in Arizona, the project is in the heart of the US copper belt, offering excellent transportation logistics.
• Infrastructure: The project benefits from a world-class road system and a rail line connecting the east and west coasts of the US, facilitating efficient distribution of copper cathode.

Conclusion and Investment Perspective

The Cactus Project presents a compelling investment opportunity with exceptional PFS results, a strong management team, and a strategic position within the US. The project's low costs, significant resource base, and favorable market outlook for copper make it highly attractive. The company is well-funded to advance the project to FID, and the recent royalty buy-back further enhances shareholder value. The "copper from the US for the US" narrative is a key differentiator, aligning with national strategic interests.
