Canuc details seismic survey at East Sudbury project

Executive Summary

• Canuc Resources Corp. has initiated a high-resolution 2-D and VSP seismic survey on its 100%-owned East Sudbury project (ESP) in Ontario, supported by Natural Resources Canada.
• The survey targets the McLaren Lake fault zone (MLFZ), a known MIAC system hosting Cu-Au, Co, Ni, and PGE mineralization, to map subsurface structural controls and guide future exploration.
• Seismic data will be integrated with gravity gradiometric results and analyzed using AI/machine learning to identify prospective large-scale IOCG-type source deposits, with drill testing targeted for mid-2026.

Key Details

• Project Location & Size: East Sudbury Project (ESP), 100%-owned, spanning ~200 square kilometres (~19,710 hectares), located ~20 km east of Sudbury, Ontario.
• Survey Scope & Technology: Acquisition of combined high-resolution 2-D surface and VSP (vertical seismic profile) seismic data using >1,300 autonomous node sensors and low-impact Vibroseis methods.
• Target Area: McLaren Lake fault zone (MLFZ), a known Metasomatic iron alkali-calcic (MIAC) system within hydrothermally altered rocks.
• Line Coverage: 13.5 kilometres of seismic lines acquired along roads and access, providing pseudo-3-D subsurface coverage at select locations via proprietary osDesign software.
• Operational Timeline: Crew of ~15 personnel; field activities expected to be completed within 7–10 days.
• Data Integration & AI: Results will be combined with a recently completed Gravity Gradiometric Survey by Bell Geospace Ltd. and other geological data. AI and machine learning will be applied for holistic analysis to improve data quality, interpret fluid migration pathways, and reduce surface/environmental impact.
• Future Exploration Plans: Aims to identify prospective large-scale IOCG-type copper-gold-cobalt source deposits for drill testing as early as mid-2026.
• Technical Oversight: Reviewed and approved by Seymour Sears, BA, BSc, PGeo (non-independent qualified person per NI 43-101).

Notable Quotes

• Andrea Crook, Founder & CEO, OptiSeis Solutions Ltd.: "This project aims to image the subsurface structural controls governing the deposit, with a focus on deeper features. OptiSeis has extensive experience working in these complex structural environments and the combination of surface and borehole (VSP) seismic data has the potential to map the true depth and full lateral extent of this mineralization."
• Chris Berlet, President & CEO, Canuc Resources Corp.: "Canuc is moving quickly to collate data in the search for large-scale source deposits on the company's ESP claim holdings... These surveys, and their interpretation, will lead Canuc into an exciting new exploration phase on the company's 100-per-cent-owned ESP claim group... We hope to be targeting the prospective large-scale IOCG-type copper-gold-cobalt source deposits that may be identified by this work, for drill testing as early as possible after mid-year 2026."
