Thunder Bay North District, Tashota-Onaman Greenstone Belt, Northwestern Ontario

Muriel-Marr is a large, district-scale exploration project covering 8,287 hectares in Ontario’s Tashota-Onaman greenstone belt. The property hosts multiple mineralized trends with potential for skarn-related copper-gold-silver, VMS-style polymetallic mineralization, and LCT pegmatites. The project is road-accessible and remains largely underexplored despite strong historic showings.

The Muriel-Marr project was originally staked to cover large tourmaline-bearing pegmatites hosted in mafic volcanics near a peraluminous granite. Subsequent staking significantly expanded the property to capture multiple historic high-grade base and precious metal occurrences associated with electromagnetic conductors. Noronex Ltd. (2018–2022) confirmed base and precious metal mineralization at several historic trenches, validating earlier results.

The project hosts multiple mineralization styles, including skarn and contact-related sulphide mineralization with high-grade copper, gold, and silver; VMS-style polymetallic mineralization associated with felsic-mafic volcanic contacts and strong EM conductors; and tourmaline-bearing pegmatites with potential LCT (lithium-caesium-tantalum) mineralization.

Multiple historic trenches returned strong values, including:

• J.J. Perry trench: Up to 16.22% Cu and 221.5 g/t Ag
• Holland-Chellew occurrence: Up to 12% Cu, 3 g/t Au, 185 g/t Ag
• Kindle trench: Up to 4.23% Cu, 3.88 g/t Au and 43.1 g/t Ag
• Galena vein trench: 5.8% Zn and 52.1 g/t Ag
