Advancing the 100%-Owned Cam Copper Project Near Kirkland Lake, Ontario

Northstar Gold Corp. (CSE: NSG) is advancing the potential near-term extraction of Zone 2 high-grade copper-gold-silver VMS mineralization at its 100%-owned Cam Copper Project near Kirkland Lake, Ontario, utilizing Novamera’s innovative Surgical Mining technology.

Cam Copper is the principal demonstration and validation site for the federally supported, $11-million Surgical Mining for Critical Minerals Project being undertaken by Northstar, Novamera Inc. and Micon International Limited through DIGITAL. The project is advancing the precision extraction and recovery of up to 50,000 tonnes of high-grade mineralized material using Novamera's large-diameter rotary drilling and proprietary technology.

Northstar has been approved for up to $4 million in DIGITAL co-investment funding for the project. The company received its first $627,663 DIGITAL cash reimbursement in July, 2026, and is eligible to receive up to an additional $1.2 million in DIGITAL co-investment funding over the balance of the two-year project.

A Lower-Impact Path to High-Grade Copper Extraction

Surgical Mining is a precision, low-impact approach to mine near-surface, high-grade mineral deposits that may not be feasible for economic extraction by conventional mining methods.

Surgical Mining technology combines proprietary downhole imaging, data analytics, large-diameter precision drilling, backfilling and material recovery, with the objective of reducing mining dilution, extraction, transport and processing costs, while minimizing surface disturbance, environmental impact and permitting requirements.

Eligible proceeds from Cam Copper Surgical Mining for Critical Minerals extraction will be utilized by Northstar to finance continued expansion drilling and exploration at Cam Copper and the nearby Allied Gold Zone, creating the potential for a self-financing exploration and development model.
