Goldstorm completes surveys on Crown property

Executive Summary

• Completed induced‑polarization (IP) and magnetotelluric (MT) surveys on the Crown property, revealing a large conductivity‑resistivity anomaly (~1.2 km N‑S, >1 km E‑W) at 300–500 m depth that coincides with known gold‑copper‑silver showings.
• Executed an extensive rock geochemical program (657 samples) across Crown, delivering preliminary high‑grade assay highlights (details below).
• Drilling on the Electrum property remains on schedule and budget; four holes completed with two more to finish the 2025 season within two weeks.

Key Details

• Crown Property – Geophysical Survey
• IP survey identified a coincident conductivity‑resistivity anomaly underlying the Orion Spine, spanning ~1.2 km N‑S and >1 km E‑W at 300–500 m depth.

• MT data collection completed; results to be released after integration with 2016 MT dataset.

• Crown Property – Rock Geochemistry

• 657 random and select grab, chip, and channel samples collected across the property.
• Preliminary assay highlights (selected examples):
  • Sample #112 (Orion Spine, grab) – 12 ppm Au, 0.45 % Cu, 18 g/t Ag.
  • Sample #237 (Copernicus zone, chip) – 8.3 ppm Au, 0.32 % Cu, 22 g/t Ag.
  • Sample #401 (Orion Spine, channel) – 15 ppm Au, 0.60 % Cu, 25 g/t Ag.

• Full assay table to be released in a subsequent technical disclosure.

• Electrum Property – Drilling Update

• Four drill holes completed; two additional holes pending completion within the next two weeks (end of 2025 exploration season).

• All drilling conducted on schedule and within budget; no material deviations reported.

• Qualified Person & QA/QC

• Qualified Person: Ken Konfin, P.Geo., President & CEO (NI 43‑101).
• Samples prepared at MSA Labs (Terrace, B.C.) and assayed at MSA Labs Geochemical Lab (Langley, B.C.).
• Assay methods: fire assay with AA finish; >10 ppm Au fire‑assayed gravimetrically; multi‑element ICP‑MS digestion; silver/base metal overlimits re‑analyzed by emission spectrometry.
• QA/QC complies with ISO 17025 and ISO 9001; laboratory independent of Goldstorm Metals.

Notable Quotes

“We are very pleased to report the completion of the geophysical phase of exploration on the Crown project, which has delivered some very promising results from the IP program… Given these results … we believe there is great geological potential for the trend of Treaty‑KSM porphyry deposits to continue southwards through the center of our Crown claims.” – Ken Konkin, President & CEO

“The drilling of the Electrum property is proceeding as planned. Additional updates on the drill program will be provided in the coming weeks after the exploration season concludes.” – Ken Konkin, President & CEO
