Brossard, Québec - TheNewswire - April 16, 2026 — Windfall Geotek Inc. (CSE: WIN; OTCQB: WINKF) ("Windfall" or the "Company"), a pioneer in Artificial Intelligence (AI)-driven mineral exploration since 2005, is pleased to announce they will use their proprietary Machine Learning AI System across Precore Gold’s (CSE: PRCG) Lac Big-Rush Property located in the highly prospective area within the Chibougamau Mining Camp of Quebec, approximately 32 km from the town of Chibougamau, Quebec.  

Windfall will process Precore Gold’s consolidated geoscientific datasets to generate high-confidence, AI-driven predictive exploration targets in advance of the company’s inaugural exploration and drilling campaign, set for later this year. Preliminary results are anticipated in the next few months. The deployment of the AI system comprises two (2) distinct modeling phases.

• Model 1 (Regional Scale): Covering 365.55 sq/km at a 50 metre (146,367 datapoints) resolution. This model integrates merged magnetic data and topography with historical gold assays provided from drillhole and rock samples SIGEOM public database (Figures 1 & 2), to identify broad regional trends and structural corridors. 

• Model 2 (High-Resolution MAG survey): Covering 123.75 sq/km at a sharp 25 metre resolution. This advanced model utilizes the newly acquired Magnetic data and SRTM, processing 196,479 individual datapoints (Figures 1 & 2). 

For additional details, readers are invited to consult the press release issued by Precore Gold Corp. today.

Michel Fontaine, President and Chief Executive Officer of Windfall Geotek, commented:

“Backed by over 41 client discoveries, Windfall Geotek’s AI-driven exploration platform is redefining target generation. Through dual-signature modeling, we rank and prioritize zones using the highest similarity scores across independent predictive models. With over two decades of R&D investment and a fully cloud-powered infrastructure, we are now able to compress what traditionally takes months into just days. This integrated approach combining AI, geophysics, and geological expertise from senior geologists—positions Precore Gold to dramatically reduce its exploration footprint by up to 99% and focus capital exclusively on the most prospective targets.”
