Golden Spike Intersects Wide Zone of Low-Grade Gold-Zinc-Copper Mineralization at Gregory River

Executive Summary

• Golden Spike announced significant early‑stage drill intercepts from its eight‑hole Winkie program on the Lower Mitchell and Lode 9 Northeast targets, including up to 5.46 g/t AuEq over 0.5 m and multiple >1 g/t AuEq intervals.
• The results validate historic geochemical anomalies (copper, zinc, gold) and an IP anomaly at Lode 9, indicating new zones of copper‑gold‑zinc mineralization near surface.
• Company will integrate the data with existing surface work, conduct additional geophysics, and plan larger‑diameter diamond drilling later in the fall.

Key Details

• Lower Mitchell Target – Highlight Intercepts
• WD25‑08: 1.02 g/t AuEq over 11.65 m (31.0–42.65 m); peak 5.46 g/t AuEq over 0.5 m (31.0–31.5 m).
• WD25‑05: 0.65 g/t AuEq over 11.4 m (47.1–58.5 m); includes 1.48 g/t AuEq over 0.5 m (38.2–38.7 m).

• Additional notable intervals: 0.68 g/t AuEq over 29.45 m, 0.40 g/t AuEq over 5.3 m, and several sub‑meter high‑grade zones (>3 g/t AuEq).

• Lode 9 Northeast Target – Highlight Intercepts

• WD25‑01: 0.54 % Cu, 0.10 g/t Au, 0.08 % Zn over 2 m (7–9 m).
• WD25‑01: 1.06 % Cu, 0.04 g/t Au, 0.05 % Zn over 0.6 m (33.25–33.85 m).

• WD25‑02: 0.56 % Cu, 0.21 g/t Au, 0.02 % Zn over 0.75 m (34.95–35.7 m).

• Program Overview

• Total of eight shallow holes, ~423.7 m drilled between 9 July and 2 August 2025 using a UTV‑mounted Winkie drill (27 mm AQ core).
• Core recovery >95%; all core sampled (average sample length ≈0.94 m).

• Drilling contractor: Majors Contracting Ltd., Deer Lake, NL.

• Analytical Methodology

• Samples processed by Eastern Analytical Laboratory (ISO‑17025 accredited).
• Gold fire‑assayed (30 g) with AA finish; 34 elements via ICP‑OES; Cu/Zn overlimits re‑analyzed.

• QA/QC: one standard/blank per ~20 samples plus certified reference material insertions.

• Geological Context

• Lower Mitchell: breccia‑stockwork copper‑gold±zinc prospect within weathered basaltic host; quartz‑carbonate veining and sulfide mineralization (pyrite, chalcopyrite, sphalerite, arsenopyrite).

• Lode 9 Northeast: volcanogenic massive sulphide (VMS) setting with IP anomaly correlating to historic Cu/Zn soil anomalies.

• Next Steps

• Integrate drill data with surface geochemistry, mapping, and airborne geophysics.
• Conduct targeted ground‑geophysical surveys over Lower Mitchell to define mineralization orientation.
• Plan larger‑diameter diamond drilling later in the fall; continue ATV‑accessible prospecting and soil sampling (623‑sample grid at Steep Brook North pending results).

Notable Quotes

• Keith Anderson, President & CEO: “We are very pleased with the Winkie drill results, which certainly exceeded our expectations… The true overall dimensions and potential grades of this early‑stage prospect remain to be determined, and our technical team will be reviewing these results in more detail and planning additional work, including diamond drilling.”
