ATEX Resources: New Emerging Copper District in Chile | Chris Beer and Jimmy Connor

Key Concepts

• Porphyry Copper-Gold System: A large-scale mineral deposit formed by hydrothermal fluids associated with magmatic intrusions.
• Breccia (B2B Zone): A rock composed of broken fragments of minerals or rock cemented together; in this context, a high-grade mineralized zone located above the main porphyry.
• Copper Equivalent (CuEq): A metric used to express the total value of various metals (gold, silver, molybdenum) in a deposit as if they were all copper.
• Hyperspectral Alteration Mapping: A remote sensing technique used to identify specific clay and alteration minerals on the surface that indicate the presence of porphyry systems.
• Tenor: The grade or concentration of a metal within an ore body.
• Daughter Hole: A secondary drill hole branched off from a primary "parent" hole to test adjacent areas or extensions of a deposit.

1. Company Overview and Resource Growth

ATEX Resources has transitioned from a junior explorer to a significant developer over the last four years. The company focuses on the Valyriano project in Chile.

• Resource Progression:
  • 2023: Initial resource of 1.4 billion tons at 0.67% CuEq.
  • 2025: Updated resource of 2 billion tons at 0.8% CuEq.
• Future Outlook: The company plans to update the resource again in late 2027, focusing on expanding the Valyriano target and testing adjacent porphyry clusters.

2. Geological Context: The "Porphyry Superhighway"

ATEX operates in a highly prospective region of Chile, approximately 100 km south of the prolific Vicuña district (home to Filo Corp and NGX).

• Strategic Location: The area is characterized by a fully preserved copper-gold system.
• Scale: The Valyriano deposit currently contains 20 million tons of copper equivalent and 15 million ounces of gold in situ.
• Grade Advantage: The deposit’s grade (0.8% CuEq) is approximately double the global average for copper-gold porphyry systems (0.4%).

3. The B2B Breccia and Mineralized Corridor

The discovery of the high-grade B2B breccia zone significantly increased the company's market valuation.

• Structure: The B2B zone sits 500 meters above the main porphyry system, which is expected to allow for more efficient future mining.
• Expansion: Recent drilling (Hole 19A/B) expanded the strike length of the B2B breccia to approximately 700 meters.
• Mineralized Corridor: Drilling in the "rhyolite" host rock (Hole 34) revealed a 1,100-meter intercept of 0.72% CuEq, indicating that the wall rock surrounding the porphyry is intensely mineralized.

4. Metallurgy and Technical Performance

The project demonstrates exceptional metallurgical characteristics, which are critical for project economics:

• Recovery Rates: 94–95% in the breccia zone.
• Concentrate Quality: Produces a 33% copper concentrate (vs. the 24% global average) with 14 grams of gold per ton.
• Purity: The concentrate is notably free of deleterious elements like arsenic.

5. Strategic Asset Management

• Surface Rights: ATEX has acquired 14,000 hectares of surface rights, which simplifies access and long-term development negotiations.
• Novo Horizonte Acquisition: A new 10,000-hectare property acquired in January 2026. It exhibits similar hyperspectral alteration signatures to Valyriano. Exploration (geophysics/geochemistry) is scheduled for late 2026, with drilling planned for 2027.
• Operational Efficiency: ATEX maintains a low drilling cost of approximately $1,100 USD per meter.

6. Financial Position

• Cash on Hand: Approximately $150 million USD.
• Funding Strategy: The company is fully funded for at least two more years of exploration.
• Shareholder Base: Strong institutional support, including Agnico Eagle (15%) and Piran (10%).

7. Notable Quotes

• "We think shareholders would be better rewarded by expanding the size of the prize rather than just characterizing the prize right now." — Chris (on the strategy of prioritizing exploration over frequent resource updates).
• "The high-grade copper system can really accelerate the development of the high-grade porphyry below it." — Chris (on the strategic importance of the B2B breccia).

8. Synthesis and Conclusion

ATEX Resources has successfully identified a high-grade, large-scale copper-gold porphyry district in Chile. By focusing on the high-grade B2B breccia and expanding into the Novo Horizonte property, the company is aggressively growing its resource base. With $150 million in cash, clean metallurgy, and a proven ability to hit high-grade mineralization, ATEX is positioning itself as a major player in the region. The next phase of growth involves systematic step-out drilling to the south and east of the B2B zone and initial testing of new porphyry clusters in 2027.
