Sable Reports Drill Results Extending the Pyros Cu-Au-Mo Porphyry System, San Juan, Argentina

Sable Resources released drill results from its El Fierro Project’s Pyros porphyry system in San Juan, Argentina, on April 13, 2026. The program consisted of 11 holes totaling 3,466 meters, fully funded by partner Moxico Resources under an earn-in agreement. Key intercepts include Hole FZ-DH-25-92 with 8 meters @ 3.06% CuEq and broader zones such as 116.2 meters @ 0.45% CuEq. The company defines a large continuous mineralized footprint of approximately 720m x 580m with a ring-shaped geometry that remains open to the north and south. This follows previous exploration updates in early 2026 regarding the Zorro Project and confirms the high-grade potential of the Pyros system previously identified in mid-2025.

The news is assessed as Material - Positive. While not a new discovery like the Zorro North announcement in February 2026, it significantly upgrades the known potential of the El Fierro asset with high-grade intercepts (3.06% CuEq) that are exceptional for a porphyry system. Crucially, this work was fully funded by Moxico Resources, meaning Sable incurred no dilution to advance this value. The confirmation of a ring-shaped geometry suggests a robust mineralized center, increasing the probability of a future resource estimate. However, the market reaction may be muted compared to the January/February spike on Zorro news, as investors are currently digesting the broader portfolio rather than a single new discovery.

Sable Resources is an exploration-stage company focused on copper, gold, and molybdenum assets in Argentina (San Juan Province) and British Columbia. - Flagship Project: El Fierro (Pyros Porphyry System). This is the primary driver of value, with recent high-grade drill results defining a large footprint. - Secondary Assets: Zorro Project (new discovery potential), Don Julio (large land package returned from South32), and BC assets (Copper Queen/Prince) funded partially by royalty sales. - Strategy: Belt-scale exploration to discover Tier-1 porphyry systems, leveraging partner funding (Moxico) to reduce cash burn.
