Northstar Gold Corp. announced a borehole electromagnetic (BHEM) and surface electromagnetic (EM) survey have commenced at the Cam Copper Mine area on the Company's 100%-owned Miller Copper-Gold Property, situated 18 kilometres southeast of Kirkland Lake, Ontario. Cam Copper is a road accessible shaft mine and small-scale, past producer of high-grade 'direct shipping' copper ore centred on the historic Boston Creek Copper Trend.

A recent 4-hole, Northstar diamond drill program at Cam Copper Mine confirmed a Volcanogenic Massive Sulphide (VMS) nature to the high-grade copper mineralization, with each hole intersecting massive chalcopyrite, high-grade copper horizons grading up to 14.8% copper over 2.5 metres. A surface EM survey will define Cam Copper VMS horizon extensions and conductors over a 900-metre strike length towards the southeast, with a priority to identify areas with thicker accumulations of Cu-rich massive sulphides. A borehole BHEM survey will also be conducted on the 4 Cam Copper diamond drill holes completed in 2023.

Similar Pulse-EM technology and surveys lead to several previous VMS discoveries across Canada, including Hudbay Minerals' 2003 Lalor VMS deposit discovery in Manitoba. To further enhance copper-rich VMS drill target definition, Ronacher Mackenzie Geoscience (RMG) will compile and model historic geophysical survey data, including the digitization of historic near-surface VLEM conductors and strongly chargeable and conductive I.P. anomalies, 3D plate model airborne EM conductors and complete 3D in versions of historic magnetic data.

In the late fall of 2023, Northstar conducted a limited prospecting and sampling program covering the southeast extension of the Cam Copper VMS/exhalite trend along the contact with the Round Lake Batholith. These samples could represent extensions of VMS Zones 1 and 2 up to 900 metres along strike to the southeast of the Cam Copper Mine site. Northstar intends to follow up 2023 Cam Copper trend surface sample and 2024 EM survey targets in the spring of 2024, with prospecting, geological mapping, sampling and a Phase II diamond drill program.

Quality Control. Gold analyses is obtained via industry standard fire assay with ICP finish using 15 g to 30 g aliquots. For samples returning greater than 10 g/t gold follow-up fire assay analysis with a gravimetric finish is completed.

Based on initial fire assay gold indications as well as visual indication of mineralization and alteration, samples are selected for re-assay by the screen metallic fire assay method. Samples are also analyzed for 48 trace and major elements by ICP-MS following a four-acid digestion. In April, 2022, as a precursor to a Mineral Resource Estimate and for reporting purposes, the Company commissioned Ronacher Mackenzie Geos Science and SRK Consulting (Canada) to conduct an Exploration Target Study of the Miller Property Allied Gold Zone and No.

1 Vein. An upper range exceeding 500,000 ounces of gold averaging 2.04 g/t Au has been referenced in this study. Reported results (Northstar News Release dated July 26, 2022) verify the significance, size and gold grade potential of the Allied gold mineralizing system.

Results provide the Company and investors a fact-based conceptual tonnage and gold grade range for the Allied Syenite Gold Zone, and basis for continued expansion drilling and mineral resource development. On November 23rd, 2023 Northstar announced results from a 720 metre, 4-hole diamond drill program completed on the historic high-grade Cam Copper Mine, located 2.5 kilometres southwest of the Allied Gold Zone and also on Northstar's 100%-owned Miller Property. The Company reported all drill holes intersected lenses of Cu-rich volcanogenic massive and also on Northstar's100%-owned Miller Property.

The company reported all drill holes intersected lens of Cu-rich volcanogenicmassive sulphides, including massive and stringer chalcopyrite in drill holes intersected lenses of copper mineralizing system. The Company reported all drill hole intersected lenses of Cu-grade Cam Copper Mine.
