Northstar Signs MOU to Mine High Grade Zone 2 at Cam Copper Mine Using Novamera Surgical Mining(TM) Technologies

Vancouver, October 3, 2024 - Northstar Gold Corp. (CSE: NSG) (OTCQB: NSGCF) ("Northstar" or the "Company"), announces that Novamera Inc. ("Novamera") and Northstar have entered into a Memorandum of Understanding ("MOU", or "Novamera MOU") to model, develop and mine a potentially economically viable mineral resource* at the Company's 100%-owned Cam Copper Mine site ("Project", or "the Project") on the Miller Copper-Gold Property, 20 kilometres southeast of Kirkland Lake, Ontario (Figure 1).

The MOU agreement sets out terms under which Novamera will secure the necessary financing to Surgically Mine^TM Cam Copper Project, subject to the definition and permitting of an economic deposit. This includes a multi-staged program (the "Surgical Mining^TM Program") to test and extract material from the copper-rich, near vertical Zone 2 VMS horizon at the historic Cam Copper mine site. Zone 2 is the largest of 3 narrow, steeply dipping tabular copper horizons estimated by a previous operator to average 10% copper over a 0.85 metre true width, 42-metre strike length and a minimum 140 metre depth extent from surface¹. Northstar recently drilled 4 diamond drill holes that corroborate historic Zone 2 copper widths and grade, including a 14.8% copper over 2.45 metres intercept in drill hole CC03-23 (See Northstar News Release dated Nov. 23, 2023).

Zone 2 is interpreted to host Cu-rich Besshi-type volcanogenic massive sulphides including massive chalcopyrite and bornite and remains open to expansion along strike and down dip (Figure 2). The MOU provides the framework for both parties to gain a clear understanding of the value of Surgical Mining^TM at the Project, as well as the necessary stages for commercial deployment and extraction.

* Insufficient exploration has been carried out to define a mineral resource on the property and a qualified person has not done sufficient work to classify Cam Copper as a current mineral resource. Additional exploration including a 43-101 Technical Report, CIM and NI-43-101 reporting compliant mineral resource estimate and Preliminary Economic Assessment are required to establish the economic potential of Cam Copper.

Northstar Commentary

"This marks the second major milestone announcement for Northstar in just two weeks," said Northstar President and CEO Brian Fowler. "The Memorandum of Understanding (MOU) with Novamera for the Cam Copper Mine, along with the recently announced MOU with Hunan Nonferrous-which focuses on developing an NI43-101 gold resource at our nearby Miller Alkalic Intrusive Complex (see Northstar's news release dated September 19, 2024)-represents yet another non-dilutive approach to advance and monetize our high-grade gold and copper projects. We're thrilled to collaborate with Novamera to establish a sustainable mining operation at Cam Copper, utilizing their cutting-edge, eco-friendly Surgical Mining™ technology for critical minerals."

Fowler further emphasized the importance of this development: "The Novamera MOU significantly strengthens Northstar's ability to explore and develop the narrow, high-grade copper zones at Cam Copper. Looking ahead, this partnership could pave the way for further agreements to explore and exploit a 3-kilometre stretch of VMS copper horizons, including the historic high-grade Amity and Patterson Mines on the adjacent Boston Creek Mines Property, as outlined in a Letter of Intent dated May 16, 2024."

Novamera Commentary

Novamera's President and CEO Dustin Angelo states, "We are excited to partner with the Northstar team to potentially bring Zone 2 at the Cam Copper Mine into production. At Novamera, our mission is to empower companies like Northstar to unlock small-scale, high-value mineral resources that are critical in today's market. Through our advanced AI and machine learning technologies, we enable mining companies to leverage conventional large-diameter drilling equipment to surgically extract deposits with minimal upfront capital and a quicker path to profitability. This innovative approach offers a transformative model for the industry, allowing mining companies to capitalize on deposits that would otherwise be untapped using traditional methods."

What is Surgical Mining^TM?

Surgical Mining^TM is Novamera's proprietary mining process that combines its mapping, positioning and steering technologies with conventional drilling equipment to exploit narrow, high-grade copper deposits that are the size and style of the Cam Copper Mine No. 2 Zone. This innovative solution is a more cost-effective, rapid path to production that radically reduces environmental and social impact. Given the low upfront capital costs and minimal development costs, Surgical Mining^TM offers junior mining companies the opportunity to exploit small, narrow, high-grade mineralized zones, generating sustainable cash flow to fund strategic plans and reduce their reliance on the capital markets. In addition, permitting time and expense are generally significantly reduced owing to the small environmental footprint and operational scale.

MOU Stages, Turnkey Mining Provision and Project Funding

The Novamera MOU sets out a 4-Stage process to Surgically Mine^TM copper at Northstar's Miller Copper-Gold Property over the next 12-18 months that includes:

• Stage 1 Conceptual surgical mining economic desktop evaluation, 3D block model development (near completion).

• Stage 2 Guidance tool calibration activities, mine permitting, environmental impact assessment.

• Stage 3 Initial surgical mining employing rotary drilling methods.

• Stage 4 Expansion of Surgical Mining^TM to other areas of the Cam Copper Project.

Upon completion of the Stage 1 Economic Forecast, Stage 2 Mine Plan and having entered into a definitive agreement related to the Transaction, Novamera will engage with prospective financial partners and government grant agencies to secure financing for Stage 3 of the Cam Copper Mine Zone 2 Surgical Mining^TM Program. Project funding is not expressly guaranteed by Novamera. In the event Novamera secures project funding, or the necessary portion thereof to commence Surgical Mining^TM in Zone 2, a separate agreement will be entered into defining commitments and obligations related to project financing between the Parties and corresponding financial partner(s).

Stage 4 Expansion Project Area and Turnkey Solution First Right of Refusal

Upon completion of Stage 3 Surgical Mining^TM, Novamera will have a Right of First Refusal ("ROFR") to provide the Turnkey Solution at other steeply dipping mineral deposits within the Project Area (Figure 1), provided those veins are applicable to be mined using Surgical Mining^TM. Other deposits where Surgical Mining^TM is not the most practical or economic are outside the scope of this MOU and the ROFR will not apply.

Underground Development and Historic Copper Production at Cam Copper - Direct Shipping Ore

The Cam Copper Mine hosts at least three separate lenses (Zone 1, Zone 2, Zone 3 and a possible Zone 4- Figure 2) of massive copper sulphides about 30-50 metres apart striking and plunging southeast along the contact with the Round Lake Granite Batholith. Underground development took place between 1929 and 1953 which includes sinking of a 220' (66.7m) vertical shaft with 213' (64.5m) of cross cutting and 267' (80.9m) of drifting. The recent drilling and surface sampling results substantiate historic reporting of a 1955 shipment of 346 tons of hoisted underground ore which produced 43,411 lbs. of Cu² at a Noranda smelter for a recovered grade of 6.3% 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% Cu, 0.84 oz/t Ag and 0.03 oz/t Au³, presumably from Zone 1.

Bornite was reported to be common in Zone 2 with the bornite rich pods of massive sulphides remaining open down plunge to the southeast.⁴

Boston Creek Mines Historic Copper Production - Direct Shipping Ore

Additional high grade Cu production was recorded at the Amity and Patterson Mines located on Boston Creek Mines Property less than 2 km to the northwest of Cam Copper (Figure 1). The Amity hosts a 1020' 2-compartment shaft with 5 levels of development (50, 125, 475, 600 and 1000' levels). The best reported ore in the mine graded 7-8% Cu across 11 feet at the 350' level^5,7. Multiple shipments of direct shipping ore were reportedly sent to the Noranda smelter between 1926 and 1955.

The Patterson Mine, located less than 1 kilometre to the northwest of Cam Copper along the same stratigraphic horizon hosts a 520' sub vertical shaft with 4 levels of development (125, 250, 375 and 500' levels). Ore shoots up to 4 feet in width produced ore shipments that averaged 8% Cu^6,7 and 0.5 oz/T Ag in 1928-29. Overall, the Patterson Mine shipped >4000 Tons of direct shipping ore directly to the Noranda Smelter between 1926 and 1955.

Northstar recently expanded its coverage of the South Boston Creek Copper Trend by signing Letters of Intent with owners of the neighboring and adjacent Boston Creek Mines (Please see Northstar News Release dated May 16, 2024) and Philip Property (Please see Northstar News Release dated May 28, 2024). Three recently defined near-surface EM survey conductors on the Miller Copper-Gold Property, believed to represent near-surface volcanogenic massive sulphides (VMS) horizons, extend southeast onto the Philip Property, with the central conductor extending as much as 350 metres across the property line. Northstar's LOI agreements effectively consolidate the 4-kilometre South Boston Creek Copper Trend, providing the Company an exploration buffer zone, a 6-month exclusivity period and 1 year Right of First Refusal to conduct due diligence studies and negotiate possible acquisition terms.

2024 EM Survey Defines 350m Long, Possible Near-Surface VMS Drill Target South of Cam Copper Mine

Northstar recently completed down-hole and grid-scale EM geophysical surveys over a 900 metre distance from Cam Copper Mine, defining a 350 metre long, 200 Siemens near-surface EM conductor, 600 - 900 metres along strike to the southeast of the mine site. (Please see Northstar News Release Dated May 16, 2024)

Prior to drill testing the 200 Siemens Conductor, Northstar recently expanded its coverage of the South Boston Creek Copper Trend by signing Letters of Intent with owners of the neighboring and adjacent Boston Creek Mines and Philip Property. The Boston Creek Mines Property contains 2 historic high-grade copper shaft mines along the northwestern half of the South Boston Creek Copper Trend, immediately adjacent to the Miller Copper-Gold Property. Three recently defined near-surface EM survey conductors on the Miller Copper-Gold Property, believed to represent near-surface volcanogenic massive sulphides (VMS) horizons, extend southeast onto the Philip Property, with the central conductor extending as much as 350 metres across the property line. Northstar's LOI agreements effectively consolidate the 4-kilometre South Boston Creek Copper Trend, providing the Company an exploration buffer zone, a 6-month exclusivity period and 1 year Right of First Refusal to conduct due diligence studies and negotiate possible acquisition terms.

Northstar is positioning to drill test the Zone 2 Extension Conductor in Q4, 2024.
