Myriad Uranium Completes Large-Scale Radiometric and Magnetic Geophysical Survey Across Its Copper Mountain Project

Executive Summary

• Myriad Uranium Corp. completed a large‑scale helicopter‑borne radiometric and magnetic survey over the entire 191.8 km² Copper Mountain Uranium Project.
• The survey, performed by Precision Geosurveys, collected 2,114 line‑kilometres of data at 100 m line spacing, providing high‑resolution magnetic and gamma‑ray measurements to refine exploration targets.
• Preliminary unprocessed images are already available; final processed results are expected in January 2026 and will guide the next phase of drilling planned for 2026.

Key Details

• Survey Scope: 191.8 km² area, 2,114 line‑kilometres flown at 30 m altitude, north–south orientation, 100 m line spacing with 1,000 m tie lines.
• Equipment Used:
• Magnetic sensor – Scintrex CS‑3 (or Geometrics equivalent) cesium vapor magnetometer; sensitivity <0.01 nT, 20 Hz sampling (1–2 m spacing).
• Radiometric sensor – Medusa gamma spectrometer system with 21 L NaI(Tl) crystals, 512 channels, 1 Hz sampling.
• Data Accuracy: Flight line accuracy ±8 m; elevation control via laser altimeter; positioning via WAAS‑enabled GPS.
• Processing Timeline: Preliminary uncorrected magnetic and radiometric images received; full processing and data products expected January 2026.
• Historical Context: References 1982 Bendix study estimating ~655 Mlb U in the broader district and ~245 Mlb U in the “Contral Area” (≥70 % owned by Myriad). These are historical, non‑NI 43‑101 estimates.
• Future Plans: Processed survey results will be used to prioritize targets for a new drilling program slated for early 2026.
• Qualified Person: George van der Walt, MSc., Pr.Sci.Nat., FGSSA – consulting geologist and NI 43‑101 Qualified Person reviewed the technical information.
