NORTHSTAR GOLD CORP. COMMENCES DRILLING AT HISTORIC HIGH-GRADE CAM COPPER MINE

Northstar Gold Corp. has commenced diamond drilling at the historic Cam copper mine, a former high-grade copper producer on the company's 100-per-cent-owned Miller copper-gold property, situated 18 kilometres southeast of Kirkland Lake, Ont.

Northstar recently reported the company has contracted Pelletier Drilling Ltd. of Chapais, Que., to conduct a 700-metre, phase 1 diamond drill program targeting near-surface, high-grade copper mineralization extensions at the Cam copper mine. Drilling has commenced and phase 1 is expected to be completed by the end of the month.

Northstar's phase 1 Cam copper drill program is predicated on recent sampling results (see Northstar's news release dated July 5, 2023) and a new 3-D mineralization model incorporating detailed historic mine sampling, drilling, development and production records. The company's intention is to verify a volcanogenic massive sulphide (VMS) paragenesis at Cam copper mine, discover new copper zones, replicate and expand upon historic Zone 1 drill hole intercepts, which include 12.4 per cent Cu over 2.4 metres (hole No. 3), 7 per cent Cu over 1.8 m (hole No.4), and Zone 2 intercepts including 23.1 per cent Cu over 1.4 m (hole No. 4) and 9.6 per cent Cu over 2.6 m (hole 2-1).

"Cam copper mine represents a unique and compelling high-grade copper exploration opportunity that dovetails with Ontario's critical minerals exploration focus," states Brian P. Fowler, president, director and chief executive officer of Northstar. "While gold exploration at the Miller property continues to have significant upside and remains a focus of the company, Northstar sees significant expansion upside at Cam copper that can be more easily fast tracked. Phase 1 drilling is aimed to substantiate this."

Mineralized zones at Cam copper have been defined by surface mapping and sampling, historic drilling, and EM (electromagnetic) and IP (induced polarization) surveys for 65 metres along strike to the southeast, representing at least 170 metres of down plunge depth extent, well below the 200-foot level of the historic mine workings. Additional EM and IP targets extend for up to 900 metres along strike to the southeast, lateral to the Round Lake Granite batholith contact.

The historic Cam copper mine

The Cam copper mine hosts at least two separate lenses (Zone 1 and Zone 2) of massive copper sulphides about 40 metres apart, striking and plunging southeast along the contact with the Round Lake Granite batholith. Laminated sulphides hosted in tuff with lower-grade copper values are reported to occur on either side of the massive copper sulphide bands. The copper mineralization is focused along the steeply plunging intersection of northeast-striking silicified tectonic breccias with southeast-striking, vertically dipping bands of silicious sulphide facies iron formation, within felsic and mafic tuffaceous units. The copper zones remain open down plunge to the southeast. The nearby former-producing Amity and Patterson copper mines occur within the same geologic formation along strike to the northwest.

Underground development and historic copper production

Underground development at Cam copper mine took place between 1929 and 1953, and includes a 220-foot (66.7 m) vertical shaft, 213 feet (64.5 m) of crosscuts and 267 feet (80.9 m) of drifts. Historic drill results and Northstar's recently reported surface sampling results (see Northstar news release dated July 5, 2023) substantiate historic reporting of a 1955 shipment of 346 tons of hoisted underground ore which produced 43,411 pounds of Cu at a Noranda smelter for a recovered grade of 6.3 per cent Cu. The ore was shipped directly from the mine site to the smelter without requiring further concentration in a mill. A previous 1948 shipment of 22 tons of ore to Noranda reportedly graded 12.72 per cent Cu, 0.84 ounce per ton (oz/t) silver (Ag) and 0.03 oz/t gold (Au), presumably from Zone 1.

Historic drilling

Historic drilling intercepts in Zone 1 by Consolidated Golden Arrow Mines Ltd. at the Cam copper mine include:

• 1.6 per cent Cu over 6.6 feet (two m) in DDH 1;
• 9.8 per cent Cu over four feet (1.21 m) in DDH 1A;
• 12.4 per cent Cu over 7.8 feet (2.36 m) in DDH 3;
• 7 per cent Cu over six feet (1.82 m) in DDH 4.

Average sampling grade reported in Zone 1 was 8.5 per cent Cu over a true width of 4.4 feet (1.33 m) indicated over 100 feet (30.3 m) along strike.

Historic drilling intercepts by Consolidated Golden Arrow Mines in Zone 2 include:

• 10.5 per cent Cu over 0.5 foot (0.15 m) in DDH 2;
• 19.9 per cent Cu over 3.1 feet (0.94 m) in DDH 3;
• 23.1 per cent Cu over 4.6 feet (1.39 m) in DDH 4 -- down plunge extension below workings;
• 12.4 per cent Cu over 3.3 feet (one m) in DDH 7 -- down plunge extension below workings.

Average sampling grade reported in Zone 2 was 10 per cent Cu over a true width of 2.8 feet (0.85 m) indicated over 140 feet (42.4 m) along strike.

Bornite was reported to be common in Zone 2, with the bornite-rich pods of massive sulphides remaining open down plunge to the southeast.

About Northstar Gold Corp.

Northstar's primary exploration focus is the advancement of the company's flagship, 100-per-cent-owned Miller gold property, situated 18 km southeast of Kirkland Lake and Agnico Eagle Mine's Macassa SMC gold mine. The company's strategy is to develop either a minimum material (over one million ounces) high-grade gold mineral resource to potentially supplement a nearby mining operation or a stand-alone mining operation at the Miller gold property.

Since going public by initial public offering in late 2020, Northstar has spent over $4.7-million in exploration at Miller, resulting in the discovery of a series of broad, near-surface, shallow-dipping sheeted quartz-gold-telluride vein structures in the Allied syenite (Allied gold zone) and Planet syenites and numerous 70-to-750-gold-gram-per-metre drill hole intercepts. Drilling to date at the AGZ has returned near-surface gold intercepts that include 6.6 grams per tonne gold over 117.0 metres, 4.0 grams per tonne gold over 50.6 metres, 1.4 grams per tonne gold over 118.5 metres and 1.2 grams per tonne gold over 107.3 metres. Stepout AGZ drilling in 2021 intersected peripheral steeply dipping copper-gold-bearing structures (CG1 and CG2 zones) returning intercepts that include 9.41 grams per tonne gold and 1.03 per cent copper over 3.0 metres. The AGZ shares numerous compelling similarities to Agnico Eagle's nearby Upper Beaver deposit, currently in the predevelopment stage.

In April, 2022, as a precursor to a mineral resource estimate and for reporting purposes, the company commissioned Ronacher Mackenzie Geoscience 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 grams per tonne gold has been referenced in this study. Results were reported July 26, 2022, verifying 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.

In addition to drill testing extensions of the high-grade Cam copper mine this fall, Northstar is positioning to conduct a phase IIIA Allied gold zone lateral and depth expansion drill program on the Miller gold property.

Northstar has three additional 100-per-cent-owned exploration projects in Northern Ontario, including the recently acquired 1,200-hectare Rosegrove property situated 0.5 kilometre from the Miller gold property, the 4,650-hectare Bryce gold property (includes the recently optioned Britcanna lease), an intrusive-gold/PME VMS (volcanic massive sulphide) project located along the projected east extension of the Ridout break and the recently expanded Temagami-Milestone copper-nickel-cobalt critical minerals property located in Strathcona township. Northstar is advancing all three properties to enhance monetization opportunities.
