Northstar Completes Diamond Drill Program at Miller Copper-Gold Property New 15.76 Metre Copper Zone Discovery

Vancouver, British Columbia--(Newsfile Corp. - January 9, 2025) - Northstar Gold Corp. (CSE: NSG) ("Northstar" or the "Company"), is pleased to announce the recent completion of a 7 hole, 1,465 metre diamond drill program at the Company's 100%-owned Miller Copper-Gold Property, situated 18 kilometres southeast of Kirkland Lake, Ontario. Wiijiiwaagan Drilling Limited Partnership, a partnership between Boart Longyear and Matachewan First Nation, conducted the program between November 23rd and December 12th, 2024.

Northstar drilling targeted near-surface copper-gold-silver volcanogenic massive sulphide (VMS) mineralization and associated EM, IP and magnetic geophysical anomalies over a 1,000 metre southeast strike extension of the historic, direct-shipping high-grade Cam Copper Mine (Please see Northstar News Release Dated May 16, 2024). In late November, 2023, Northstar drilling intersected a number of discrete high-grade VMS copper horizons at Cam Copper Mine, including 14.8% copper over 2.45 metres in Zone 2 (See Northstar News Release dated Nov. 23, 2023). The Company expects to begin reporting preliminary drill results by late January, 2025.

New 15.76 Metre Copper Zone Discovered 500 Metres Southeast of Cam Copper Mine (Fig. 1)

Northstar drill hole CC-07 discovered near surface, sub-seafloor replacement-style chalcopyrite mineralization in multiple horizons over a core length of 15.76 metres (47.24m to 63m), 500 metres southeast of Cam Copper Mine Zone 2. Chalcopyrite mineralization is observed to be associated with multiple gabbro intrusive contacts within a sequence of mafic to intermediate bedded tuffs. The CC-07 copper mineralization drill hole intercept occurs 45 metres below and 20 metres along strike from a recently sampled, historic 3 metre-wide surface trench with massive chalcopyrite and bornite mineralization assaying up to 17.9% copper and 16.2 g/t silver (Please see Northstar News Release dated July 18, 2024). This new copper zone remains completely open along strike and at depth.

While assay results from drill hole CC-07 are pending receipt, visual assessment of this important new style of copper mineralization south of Cam Copper Mine, on its own merit, warrants near-term follow-up and step-out drilling.

Additional 2024 Diamond Drill Program Observations

  • Almost every drill hole in the 2024 program intersected multiple bands of massive to semi-massive sulphide or stringer-type sulphide mineralization proximal (or in direct contact) with pervasive sericite-altered layers of intrusive gabbro sills and mafic / intermediate tuffs. This implies gabbro intrusives are the likely metal and heat source for most of the observed VMS sulphide mineralization on the Miller Copper-Gold Property.

    This newly recognized association between gabbro bodies of various dimensions and copper mineralization adds considerable geological potential to the Property, as gabbro intrusives are known to be expansive and prolific along strike and at depth, including areas higher in the metavolcanic sequence that have yet to be explored.
