Meet global mining companies in New York

ATEX Resources (TSXV: ATX; OTCQB: ATXRF) hosts the Valeriano copper-gold project in Chile and is knocking on the door of joining the list of the top 10 undeveloped copper projects worldwide. Valeriano is adjacent to the El-Encierro deposit, operated by Antofagasta and in close proximity to other active projects in the area with ownership among Teck Resources, Newmont Mining, Lundin Mining and BHP.

The Company recently announced a Mineral Resource estimate, proving to be the largest copper discovery in Chile in over a decade with a combined 2 Bt of 0.78% CuEq. Building on the success of the Phase V exploration program, delivering the best drill results to date, ATEX has commenced Phase VI drilling focusing on new discoveries, defining the recently discovered high grade (+2% CuEq) breccia zone ("B2B") which is closer to surface, and further extending the high grade porphyry core and understanding the limits of the system which remains open in all directions with significant optionality and scalability.

What do you see as the key risks and challenges facing your company at the moment and how are you overcoming these?

Risks are typical of an exploration stage company, however ATEX operates in a stable mining jurisdiction with strong ESG practices and backed by long-term supportive shareholders.

What do you think makes your company such a compelling investment?

Valeriano has experienced rapid geological success in a short timeframe and the system remains open in all directions. It is 100% in Chile, lower altitude vs. peer projects in this region, clean metallurgy, high copper-gold recoveries, strong management team and board with extensive experience in South American exploration and discoveries. ATEX presents a compelling case for a meaningful upward stock re-rate as the project advances.

What are the top 3 key investor takeaways?

1. Still in the early innings, Valeriano already ranks among the largest copper-gold deposits with a high quality grade profile.

2. The limits of the system still remain unknown.

3. Valuation discount to peers presents an attractive entry point as ATEX continues to de-risk Valeriano and has brought on Agnico Eagle as its largest shareholder and delivered a world-class Mineral Resource update.
