Northstar Gold Corp.

Gold exploration and development project

On July 5, 2023, Northstar announced the results of a surface sampling program at the historic Cam Copper Mine site on the Company’s 100%-owned, flagship Miller Property, situated 18 km southeast of the town of Kirkland Lake, Ontario.  The Cam Copper Mine is a road-accessible satellite high-grade copper system situated 2.4 km southwest of the Allied Gold Zone, the advanced, near-surface bulk-tonnage alkalic gold-telluride exploration target being actively explored by Northstar.

*The Exploration Target estimate highlights the exploration potential of the known gold zones on the Miller Gold Property. The quantity and grades are purely conceptual in nature. Insufficient exploration has been carried out to define a mineral resource on the property. A qualified person has not done sufficient work to classify this Exploration Target estimate as current mineral resources and the Company is not treating this Exploration Target estimate as current mineral resources. These estimates must be fully verified with additional exploration work using NI43-101 reporting and CIM best practices and procedures. These values cannot and should not be relied upon and are only referred to herein as an indication of potential mineralization on the property. It remains uncertain whether a mineral resource will be delineated on the Property.  Higher grade capping @ 60g/t Au in Veins – includes all domains and 150 metre extension around Vein 1.
