Kobrea Expands Porphyry Target at El Destino - Western Malargue Mining District - Mendoza Province, Argentina

Executive Summary

• Kobrea Exploration released airborne magnetometer survey results that expand the interpreted El Destino porphyry copper‑gold‑molybdenum system to a 2.8 km × 1 km anomaly, indicating continuation of the mineralized footprint north and south beneath Pleistocene ignimbrite cover.
• The Provincial Legislature approved an Environmental Impact Statement for El Destino, permitting field work this season—including road building and drilling—to bring the project to drill‑ready status.
• The company granted 2,650,000 stock options (exercise price $0.55) and 600,000 RSUs to employees, consultants and directors; 1,400,000 of the options were issued to directors as a related‑party transaction exempt from formal valuation under MI 61‑101.

Key Details

• Survey Scope & Interpretation
• Airborne magnetic data collected April–May 2025 over the 9,487‑ha El Destino Project.
• Geophysical processing (micro‑levelling, remanence correction) shows a continuous magnetic anomaly extending ~2.8 km north‑south and ~1 km east‑west.

• Interpretation supports a porphyry Cu‑Au‑Mo system that continues beneath thin Pleistocene ignimbrite cover rock on both flanks of the exposed erosional window.

• Historical Geology & Alteration

• Surface mapping identifies phyllic alteration overprinting potassic and propylitic zones; historic sampling shows up to 1,500 ppm Cu and anomalous Au in leached caps (~1,800 m × 600 m).

• Hydrothermal breccias and quartz‑tourmaline stockwork veins are present, similar to other Late Miocene–Early Pliocene porphyry systems (e.g., El Teniente).

• Regulatory Milestone

• Environmental Impact Statement for mineral exploration ratified on 2025‑12‑09 by the Mendoza Provincial Legislature.

• Approval enables field crews to commence road construction and drilling at El Destino this season, in parallel with activities at neighboring El Perdido project.

• Equity Incentive Grants

• Options: 2,650,000 total; exercise price $0.55; vesting 50 % on grant date, remaining 50 % six months later; five‑year expiry.
• RSUs: 600,000 units; vesting 120 days post‑grant; no exercise price.

• 1,400,000 options issued to directors (related‑party transaction) – exempt from formal valuation and minority shareholder approval under MI 61‑101 sections 5.5(b) & 5.7(1)(a).

• Qualified Person

• Technical information reviewed and approved by Rory Ritchie, P.Geo., VP‑Exploration & Director, qualified under NI 43‑101.

Notable Quotes

“The results of the airborne magnetometer survey support our hypothesis that the limits of the El Destino porphyry system extend to the north and south under younger volcanic cover rock,” – James Hedalen, CEO & Director, Kobrea Exploration Corp.
