First Andes Silver continues drilling at Santas Gloria

Executive Summary

• First Andes Silver disclosed additional sulphide‑bearing epithermal intersections from its ongoing 2,000‑m diamond drill program at the San Jorge vein system.
• Eight holes (total 1,092 m) were drilled; significant breccia and mineralized zones were intersected in holes SG023, SG020, SG021, SG018, SG019, SG022, confirming structural continuity and polymetallic potential at depth.
• QA/QC results remain within acceptable tolerances, with core recoveries >90 % and all samples processed by AHK Group.

Key Details

• Drill Program: 2,000‑m diamond drilling; 8 holes completed to date, 1,092 m total depth, 188 samples (154.20 m) submitted for assay.
• Hole SG023: Hydrothermal breccia zone from 145.25–174.80 m (29.55 m); 2.40‑m massive sulphide interval (pyrite, galena, sphalerite) at 172.00 m.
• Hole SG020: 27.60‑m interval (133.00–160.60 m) with strong oxidation, sericite‑clay alteration, sulphides in breccia and dacite; structurally controlled veinlets suggest depth continuity.
• Hole SG021: 13.80‑m of brecciated, fractured rock (93.40–107.20 m) containing pyrite and galena mineralization; multiple elevated sulphide zones observed.
• Hole SG018: Broad hydrothermal breccia zone from 85.65–114.20 m (28.55 m); quartz veinlets, silicified clasts, disseminated pyrite‑dominant sulphides; intersected historic underground workings at 105.20–108.90 m.
• Hole SG019: 33.60‑m interval (80.00–113.60 m) of hydrothermally altered rock with quartz stockworks, breccias, disseminated pyrite, sphalerite, galena; historic mine void intersected at 110.90 m.
• Hole SG022: Mineralized breccias and oxidized dacite from 91.10–98.70 m (7.60 m) featuring manganese oxides and pyrite.
• Historical Context: Santas Gloria lies in a historic silver district with production dating to the 1860s; past mining occurred at much lower silver prices, underscoring strong present‑day potential.
• QA/QC: Core samples sawed, half submitted to AHK Group (ISO/IEC 17025, ISO 9001 accredited); all batches passed QA/QC within tolerance; PQ‑NQ diameter drilling; core recovery >90 %.
• Qualified Person: Dr. Christopher Wilson, PhD, FAusIMM (CP), FSEG, FGS – chief geologist and qualified person under NI 43‑101 (not independent).

Notable Quotes

“Field logging results from the company's ongoing 2025 drill campaign continue to validate the scale, continuity and fertility of the San Jorge vein system,” said Colin Smith, CEO and director.
“The sulphide‑bearing breccias intersected in SG023, SG020 and SG021 exhibit strong structural control and increasing polymetallic mineralization at depth… We eagerly anticipate the first batch of results, which we expect to receive in approximately two weeks.”
