Golden Spike Soil Sampling Outlines Gold-Zinc-Copper-Arsenic Anomalies at Gregory River

Executive Summary

• Golden Spike reported extensive 2025 soil sampling results from the Lower Mitchell, Steep Brook North and Vein Zone East targets on its 100 % owned Gregory River Copper‑Gold Property in western Newfoundland.
• The Lower Mitchell anomaly shows multi‑element (Au, Zn, Cu, As) soil grades up to 885 ppb Au, 1 520 ppm Zn, 1 797 ppm Cu and >10 000 ppm As over a 600 m strike length, remaining open to the southwest.
• Steep Brook North exhibits a 2.6 km copper‑gold soil anomaly with grades up to 581 ppm Cu and 90 ppb Au; a 1 200 m trend may extend known VMS mineralization.

Key Details

• Lower Mitchell Soil Survey (Nov 2025)
• Area surveyed: ~550 m × 560 m; 225 samples (+4 duplicates) on 12 north‑oriented lines, spaced 50 m, samples every 25 m.
• Individual sample highs: 885 ppb Au, 1 520 ppm Zn, 1 797 ppm Cu, >10 000 ppm As.
• Anomaly dimensions: 600 m strike length, 25‑100 m wide, open to the southwest; secondary north‑northeast trend intersecting main zone.
• Defined cut‑offs: Au > 20 ppb (high cores >40/60 ppb), Zn > 200 ppm (high cores >300/400 ppm), Cu > 100 ppm (high cores >150/200 ppm), As > 500 ppm (high cores >1 000/2 000 ppm).

• Historical Winkie drill holes (WD25‑05, WD25‑08) intersected AuEq 0.65–1.02 g/t over ~11 m intervals, supporting soil anomalies.

• Steep Brook North Soil Survey (Aug 2025) – Grid size: ~2.6 km × 2.0 km; 623 samples (+28 duplicates) on 200 m spaced lines, 50 m sample spacing.
  – Grade ranges: Cu 9‑581 ppm, Zn 15‑555 ppm, Au <5‑90 ppb, As <5‑214 ppm.
  – Anomaly definition: Cu > 80 ppm (high cores >100/130 ppm), Au > 6 ppb (high cores >10/20 ppb).
  – Identified a ~1 200 m northeast‑trending copper‑gold anomaly (50‑100 m wide) potentially extending the Steep Brook VMS zone; historic drill hole GR‑24‑003 returned 1.29 % Cu, 0.19 g/t Au over 1.5 m.

• Vein Zone East Soil Survey (Nov 2025) – Small grid (~200 m × 500 m); 32 samples on three north‑oriented lines.
  – No significant anomalies; grades low (Cu 4‑197 ppm, Au <5‑13 ppb).

• Regional Prospecting (Nov 2025) – Six rock samples collected; two near Camp Brook showed weak Cu–Au–Zn–As anomalies (e.g., 331 ppb Au, 805 ppm Cu).

• Laboratory QA/QC – Soil from Lower Mitchell and Vein Zone East processed by SGS (ISO/IEC 17025:2017); Steep Brook North samples analyzed by Eastern Analytical Laboratory (ISO 17025 accredited).
  – Duplicate insertion rate ~2‑5 %.

• Next Steps – Integrate soil data with Winkie drilling, airborne geophysics, and plan additional exploration at Lower Mitchell, including geophysical surveys and diamond drilling.
  – Target low helicopter usage due to ATV accessibility.

Notable Quotes

“We are very pleased with the recent soil survey results… The speed at which our team have moved Lower Mitchell from an early‑stage, low priority, narrow vein prospect, to a much more significant, wide, polymetallic exploration target is commendable.” – Keith Anderson, President & CEO
