TomaGold starts drilling program on Chibougamau

Executive Summary

• TomaGold has commenced a 53‑hole, multi‑project drilling program on its Chibougamau assets in Quebec.
• The company released results of an extensive 3‑D geological and structural interpretation for the Obalski project, identifying two major shear systems and several high‑confidence copper‑gold targets.
• Recommendations were issued to expand assay datasets, relog historic cores, and increase geophysical coverage to further de‑risk the identified mineralized zones.

Key Details

• Drilling Program: 53 holes targeting Obalski, Berrigan Mine, Radar, David, and Dufault projects; aims to discover new Au‑Cu mineralization on well‑defined targets.
• 3‑D Modeling Findings – Obalski:
• Integrated historic drilling, resistivity & metal factor geophysics, and structural data into a unified 2‑D/3‑D framework.
• Identified two dominant shear systems:
  1. North‑110° (SE‑NW) shear associated with Cu‑Au quartz veins and chlorite‑carbonate alteration.
  2. Younger NE‑SW (020°) shear hosting primarily Au mineralization.
• Intersection of these shears creates high‑permeability zones deemed prime for hydrothermal fluid flow and metal deposition.
• Copper enrichment concentrates along margins of intrusive units (dioritic/granitic contacts), supporting a magmatic‑hydrothermal genetic model.
• Defined a mineralized zone trending NNE with ~32° plunge eastward, aligning with regional shear zones.
• Predictive distance‑based modeling highlights structural intersections and lithological boundaries as highest probability targets.
• Targeting Strategy:
• Prioritize drilling at structural intersections of the two shear systems.
• Focus on intrusive‑volcanic contacts, especially where sheared.
• Pursue down‑plunge extensions along the 32° trend (currently under‑drilled).
• Explore southeastern area with complex folding and dioritic traps; assess parallel underexplored structures for additional lenses.
• Recommendations & Next Steps:
• Increase assay coverage via systematic sampling of drill cores across lithologic/structural contacts.
• Standardize core logging emphasizing alteration, structure, and pathfinder elements.
• Relog historic cores with modern multi‑element (pXRF) and trace element analyses.
• Expand high‑resolution passive & active seismic surveys in partnership with the Smart Exploration Centre.
• Broaden geochemical suite to include Ag, Zn, Bi, Te, and other pathfinders.
• Technical Review: Content reviewed and approved by Jean Lafleur, P.Geo., Vice‑President of Exploration, qualified under NI 43‑101.
