Brossard, Québec / June 18, 2026 — Windfall Geotek Inc. (CSE: WIN; OTCQB: WINKF) ("Windfall" or the "Company"), a leader in the application of Artificial Intelligence (AI) and machine learning for mineral discovery since 2005, is pleased to announce the successful modeling and extraction of the geophysical "digital signature" for the Scandium Crater Lake Deposit for Scandium Canada Ltd. (TSX-V: SCD)(See Press Release April 3, 2025-New Mineral estimate- https://wp-sccanada-2024.s3.ca-central-1.amazonaws.com/media/2025/04/03165017/04-03-2025-NR-SCD.pdf)
Utilizing its proprietary AI platform, Windfall has completed an extensive computational analysis of entire publicly datasets to fingerprint the signature to their Scandium TG zone Crater Lake deposit in the Canadian province of Québec (QC).
Technical Summary & Methodology
The project focused on the TG Scandium zone: Key technical highlights include:
- Data Integration: The AI system synthesized multi-dimensional public datasets, including high-resolution Magnetic (Figure 1), Radiometric and Topography data, alongside with available drillhole assays and surface rock samples geochemistry (Figure 2).
Signature Extraction: By isolating the specific geological descriptors of the Crater Lake Scandium mineralization, the Company has established a high-fidelity Digital Discovery Pattern. Target Generation: This proprietary signature was deployed across the entire regional land package to identify high-probability anomalies. The system did not find any Scandium target outside of the Scandium Canada claims.
The Power of Digital Exploration
Using its proprietary AI System in combination with a strong historical exploration database and SIGEOM data covering 8,803 km², Windfall Geotek identified 3 high-priority Scandium Extension Target Zones, including one of 1.91 km (Figure 2) and two extensions of the TG Scandium Deposit (0,44 and 0,53 km). Confirming exactly where the company will drill in the next weeks.
Windfall’s AI System analyzed more than 2,475 historical Scandium bearing assays (mostly in the Crater Lake deposit) using advanced machine-learning algorithms designed to recognize geological patterns and contexts associated with mineralization. In total, 3 529 702 cells measuring 50m x 50m, were evaluated by the Windfall AI System. This data-driven approach significantly decreases exploration time and costs when compared to traditional exploration methodologies.

Management Commentary
Michel Fontaine, President and CEO of Windfall Geotek, commented: “Windfall Geotek’s AI-driven targeting platform achieved a 94% accuracy rate in detecting all historically known scandium occurrences at Crater Lake, confirming the strength of its predictive model. Importantly, no equivalent signatures were identified elsewhere on the area of interest cover by the Geophysics (8,803 km²)—highlighting the rarity and strategic significance of the deposit. By analyzing over 8,803 km² of data and narrowing the search area by 99%, our technology has isolated a high-confidence digital signature directly aligned with the known mineralization. The absence of similar signatures elsewhere reinforces both the uniqueness of the deposit and the potential for a significant scandium discovery."
