## Minestarters Atlas summary

Arizona Sonoran Copper Company has filed its Pre-Feasibility Study \(PFS\) technical report for the Cactus Project, outlining strong economics for a conventional open-pit copper operation. The PFS reports a post-tax NPV8 of US$2.30 billion and an IRR of 22.8% at a base case copper price of $4.25/lb, with an initial capital expenditure of $977 million. The study projects a 20-year mine life, average annual copper cathode production of 90,090 metric tonnes, and C1 cash costs of $1.34/lb, supported by initial Proven and Probable mineral reserves of 466.83 million metric tonnes at 0.52% Total Copper.

Reasoning: The Arizona Sonoran Cactus Project PFS demonstrates robust economics with a post-tax NPV8 of US$2.30 billion and an IRR of 22.8%, supported by low operating costs, a long mine life, and significant Proven and Probable copper reserves, utilizing conventional heap leach SXEW processing.

- Positive factor: Strong project economics \(NPV, IRR, payback\)

- Positive factor: Low operating costs \(C1\)

- Positive factor: Long mine life \(20 years\)

- Positive factor: High confidence mineral reserves \(Proven and Probable\)

- Positive factor: Conventional and proven processing technology \(heap leach SXEW\)

- Positive factor: Conservative copper price assumption in base case

- Positive factor: Qualified Persons sign-off and NI 43-101 compliance

- Positive factor: High capital intensity \(low USD/tonne produced\)

- Negative factor: Permits require amendment for larger scale

- Negative factor: Non-standard definition of AISC

- Negative factor: Contingency split between plant/site and mining equipment

- Negative factor: No explicit closure cost disclosed \(only included in AISC definition\)

Facts used in scoring: 4

## Classification and evidence

**Heap Leach Route**

Polarity: neutral

Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected.

Why it applies: the document describes a heap\_leach route \("heap leach"\)
