Super Copper Announces Bonanza-Grade Gold Discovery at Castilla: Assays up to 53.8 g/t Gold and 17.7% Copper

Executive Summary

• Super Copper Corp. announced a bonanza‑grade gold discovery at its 100 % owned Castilla Copper‑Gold Project in Chile, highlighted by an assay of 53.8 g/t Au and 17.7 % Cu from a single rock‑grab sample.
• Overall sampling shows 25 % of 93 samples returned > 1 g/t Au, with multiple high‑grade copper and iron intercepts, indicating a large, multi‑commodity mineralizing system rather than isolated anomalies.
• The company will accelerate exploration, including property‑wide magnetics and IP surveys and Phase 2 drill targeting based on these results.

Key Details

• Sampling Program: 93 selective rock‑grab and float samples (Phase 1 surface sampling).
• Top Gold Assays:
• 53.8 g/t Au (Sample E02610) – quartz vein float from historic mine work.
• 15.9 g/t Au (E02567) – quartz vein float from historic trench.
• 9.38 g/t Au (E02556) – high‑grade interval.
• Top Copper Assays:
• 17.7 % Cu (Sample E02505) – float with magnetite breccia, malachite infill.
• 6.86 % Cu (E02525) – float near old mine workings.
• 4.27 % Cu (E02506) – quartz vein in quartz diorite with chalcopyrite.
• Iron Oxide Highlights: 10 samples > 50 % Fe, typical of IOCG‑style veins.
• Hit Rates:
• 24/93 (25 %) > 1 g/t Au.
• 8/93 > 1 % Cu; 24/93 > 0.1 % Cu.
• 10/93 > 50 % Fe; 23/93 > 10 % Fe.
• Geochemical Pathfinders: Elevated Co, As, Sb in several samples, supporting IOCG mineralization model.
• Location Advantage: Castilla lies within Chile’s Atacama copper‑gold belt with existing infrastructure and proximity to world‑class deposits.
• QA/QC: Samples processed by ALS Group Chile; gold fire‑assayed with AAS finish, copper via 4‑acid digestion ME‑MS61. Accredited lab with standards/blanks.
• Qualified Person: Michael Dufresne, M.Sc., P.Geol., P.Geo. (NI 43‑101 QP).

Upcoming Exploration & Catalysts

• Property‑wide detailed sampling and mapping.
• Magnetics survey to delineate magnetite‑bearing zones; IP survey to map sulfide concentrations.
• 3‑D magnetic and IP inversion modeling for refined drill targeting.
• Phase 2 drill program planning underway, using Phase 1 results to select high‑priority targets.

Notable Quotes

“These results represent a defining discovery moment for Super Copper,” said Zachary Dolesky, CEO. “Grades of 53.8 g/t gold, 17.7 % copper, and over 50 % iron are exceptional… Castilla is quickly shaping up as a potential flagship asset in one of the world’s premier copper‑gold jurisdictions.”
