Windfall Geotek Congratulates Magna Terra Minerals on Significant Copper Discoveries at the Rocky Brook Project's Restigouche Trend, New Brunswick

Executive Summary

• Windfall Geotek confirms that recent copper discoveries by Magna Terra Minerals align with high‑priority targets generated by Windfall’s AI system in September 2025.
• The AI model used a 3,417.4 km² area of public geophysical data (≈1.36 million pixels) and 26,887 copper assay training points, applying a 2,500 ppm Cu threshold to define positive training data.
• Eleven copper targets with ≥85 % similarity were identified on Magna Terra Minerals’ property, supporting the successful exploration program reported by Magna Terra on Jan 13‑15 2026.

Key Details

• Modeling Scope: 3,417.4 km² (Bathurst Mining Camp) using 694 variables from 1995 Multiparameter Survey and 2004 MEGATEM Survey; data gridded to 50 m cell size (~1,363,428 pixels).
• Training Data: 26,887 copper assays sourced from:
  1. Government of New‑Brunswick Energy & Mines drill hole database
  2. Votorantim Metals Canada
  3. Academic data (Goodfellow et al., 2003)
  4. Windfall Geotek compilation (Halfmile, Chester, Captain deposits)
• Positive Training Threshold: Cu ≥ 2,500 ppm used to select positive training points.
• Target Generation: AI system produced 11 copper targets on Magna Terra’s property with a similarity level of 85 % or higher.
• Reference Release: Results corroborated by Magna Terra Minerals’ press release (Jan 13‑15 2026) – link provided in the release.
• Commentary: Michel Fontaine, President & CEO, congratulated Magna Terra’s team and highlighted the collaborative use of Windfall’s AI tools to enhance exploration efficiency.
