Northstar Gold Corp. exploration update and closes 2nd tranche of Private Placement

Northstar's primary exploration focus is to advance and expand our near-surface, bulk-tonnage gold-telluride and more recently discovered VMS copper mineral deposits on the Company's flagship, 100%-owned Miller Copper-Gold Property, situated 18 km southeast of Kirkland Lake, Ontario. The Company's strategy is to develop a material (+1M ounce gold / high-grade copper) mineral resource base to support stand-alone mining operations at the Property. 

Allied Gold Zone

Since going public by IPO in late 2020, Northstar has spent over $5.6 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, or AGZ), one of 3 known gold-telluride-bearing syenite intrusions at Miller with numerous 70 - 750 gold gram/metre drill hole intercepts. Drilling to date at the AGZ has returned near-surface gold intercepts that include 6.6 g/t Au over 117.0 metres, 4.0 g/t Au over 50.6 metres, 1.4 g/t Au over 118.5 metres, and 1.2 g/t Au over 107.3 metres.

As a precursor to a Mineral Resource Estimate and for reporting purposes, Northstar commissioned Ronacher Mackenzie Geoscience and SRK Consulting (Canada) to conduct an Exploration Target Study of the Allied Gold Zone and No. 1 Vein in 2022. An upper range exceeding 500,000 ounces of gold averaging 2.04 g/t Au has been referenced in this study. Results were reported July 26, 2022, (Click here to view Northstar News Release dated July 26, 2022) verifying the significance, size and gold grade potential of the AGZ 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. Northstar is actively seeking a major joint venture partner to continue Allied Gold Zone exploration and expansion.

Historic High-Grade Cam Copper Mine

On November 23rd, 2023 Northstar announced results from a 720 metre diamond drill program completed on the historic high-grade Cam Copper Mine, also occurring on the Miller Copper-Gold Property 2.4 kilometres southwest of the Allied Gold. The Company reported all 4 drill holes intersected lenses of Cu-rich volcanogenic massive sulphides, including massive and stringer chalcopyrite in drill hole CC03-23 grading 14.8% Cu over 2.45m from 116.55m to 119m in Zone 2 (See Northstar News Release dated November 23, 2023). Drill results suggest Zone 2 is thickening in a southeast and down-plunge direction. Additional Zones (1, 3 and 4) also remain open along strike and at depth.

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.1,2 Northstar drilling has confirmed that Cam Copper Mine is centred on a newly recognized high-grade "Besshi-type" volcanogenic massive sulphide (VMS) copper system situated at the northwest end of a 0.9 km long southeast trending belt of VMS horizons on the Miller Copper-Gold Property. Besshi-type VMS deposits are an important global source of base metals, simplistically characterized as vented, broad sheet-like layers of magnetite, iron-copper-lead-zinc-arsenic sulphides, cobalt, sulphosalts, silver and possibly gold deposited on an ancient sea floor, hosted in volcano-sedimentary rock packages. 

Northstar has recently closed 2 financings to provide for diamond drilling and down-hole and surface EM geophysical surveys to further define copper horizon strike and down-plunge extensions of the Cam Copper VMS copper horizons. It is the Company's intention subsequently drill test these newly defined geophysical anomalies by a Phase II Cam Copper diamond drill program.

Rosegrove, Bryce and Milestone Cu-Ni-Co Properties

Northstar's 100%-owned northern Ontario exploration project portfolio also includes the recently acquired 1,200 ha Rosegrove Property, situated 0.5 km from the Miller Gold Property, the 4,650 ha Bryce Gold Property (includes the recently optioned Britcanna Lease), an intrusive-gold / PME VMS project located along the projected east extension of the Ridout Break, and the recently expanded Temagami-Milestone Cu-Ni-Co Critical Minerals Property located in Strathcona Township. Northstar is advancing all 3 properties to enhance monetization opportunities.

New Discoveries Southeast of the Cam Copper Mine

In the late fall of 2023 Northstar Gold Corp conducted a limited prospecting and sampling program covering the southeast extension of the VMS/exhalite trend along the contact with the Round Lake Batholith. The program, while abbreviated due to ground conditions, included the collection of 15 grab samples from older workings and gossanous areas. Several anomalous results in Au (0 - 2.02 g/t Au), Ag (0.15 - 26.9 g/t), Cu (41 ppm - 27,900 ppm), Pb (0.9 ppm - 3340 ppm) and Zn (12ppm - 2070 ppm) were returned from samples containing semi-massive to massive sulphides in proximity to magnetic anomalies and historic EM conductors in what could represent extensions of VMS Zones 1 and 2 for 700+ metres along strike to the southeast of the Cam Copper Mine site. 

High-Grade Cu Discovery at the Milestone Cu-Ni-Co Property

In late summer of 2023 Northstar conducted a brief prospecting program on the Milestone Property near Temagami, Ontario as a follow-up to the successful 2022 UAV mag survey and prospecting program that traced Cu-Ni-Co mineralization for 1000+ metres along the footwall gabbro contact and at least one footwall "offset-style" dike. Assay results from 29 samples collected in 2022 ranged from 0.20 - 1.52% Cu, 0.05 to 0.61% Ni and 0.005% to 0.134% Co. 

The primary objective of the summer 2023 sampling program was to locate massive chalcopyrite pods believed to exist below the footwall contact and collect additional samples from the footwall dike area. A total of 15 grab samples were collected in the program with one grab sample (C169316) of Cu-rich massive sulphides returning 9.86% Cu, 0.40% Ni, 0.30 g/t Au and 0.05% Co. This discovery was made only 40 metres away from 2022 prospecting sample E455246 which assayed 1.25% Cu, 1.31 g/t Pd, 0.46 g/t Pt, 0.41 g/t Au and 6.35 g/t Ag, located 50 metres into the footwall rhyolite. The discovery of Cu-rich sulphides within the footwall rhyolite is significant as massive sulphide pods with chalcopyrite and precious metals in the footwall rhyolite formed the main ore constituent at the historic high-grade copper Temagami Mine, located along strike 20km to the southwest. 

Overall, assays from the 2023 sampling program ranged from Cu (901 ppm - 98,600ppm), Ni (53 ppm - 5720 ppm), Co (31.6 ppm - 1240 ppm), Ag (0.3 ppm - 6.4 ppm) and Au (0.082 ppm - 0.364 ppm). Additional work is being planned in the spring of 2024 to determine the full extent of high-grade Cu-sulphide mineralization within the footwall rhyolite and explore the mineralized footwall dike in greater detail. 

The Milestone Property exhibits similar geology, mineralization, stratigraphic setting and alteration as Teck Resources former high-grade Temagami copper mine located 20 km southwest along strike. The Temagami Mine produced approximately 900,000 Tons at an average grade of 6.0% Cu during the period 1955 to 1972 (3). Both the Milestone Property and Temagami Mine share some similarities with the "footwall breccia" type ore deposits found in the Sudbury basin.

Rosegrove Property 

The Rosegrove Property is situated immediately northwest of the Miller Copper-Gold Property, and is highly prospective for alkalic intrusion-related gold-telluride and shear hosted copper-gold mineralization. In the fall of 2023 Northstar completed a property wide LiDAR survey and 634 ha MMI soil sampling program covering the central portion of the 1150 ha property. 

The LiDAR survey was successful in tracing the regional Pacaud Fault Zone along with potential splay structures or 2nd order structures with potential to host copper and gold-telluride mineralization similar to the Miller Copper Gold Property. Several prominent N-S and ENE trending structures were also identified in the southern and western areas of the property where bedrock was not obscured by the central floodplain. Northstar plans on prospecting and ground truthing several of these interpreted structures in the spring of 2024. Northstar is still awaiting analytical results from 207 MMI soil samples covering the Pacaud Fault Zone and associated structures.

On December 18th, 2023 Northstar reported it had received eligibility notice from the Ontario Ministry of Mines to receive a critical minerals exploration grant of up to $80,532.50 from the Ontario Junior Exploration Program (OJEP). Grant proceeds cover up to 50% of Northstar's eligible, 2023-2024 critical minerals exploration expenditures at the Rosegrove Property. 

Northstar Closes Third Tranche Private Placement

Northstar also announces the Company has closed a third tranche of its previously announced 
non-brokered private placement (the "Offering") of hard dollar units ("Units"). 

The Offering consisted of 1,090,910 hard dollar Units for a total of $60,000. This is in addition to closing the first and second tranches consisting of 12,348,479 Units for aggregate gross proceeds of $738,999.64 as previously announced on December 13, 2023 and December 29, 2023. 

A total of $717,999.54 Critical Minerals Eligible flow-through shares were raised on an 
over-subscribed basis, exceeding the original minimum Critical Minerals Eligible flow-through target of $600,000 reported December 29, 2023. 

All securities issued under the Offering are subject to a statutory four month hold period from the closing date under applicable Canadian securities laws. 

The gross proceeds from the sale of the flow-through shares will be used to incur eligible Canadian Exploration Expenses ("CEE") which will be used primarily to fund the Critical Minerals exploration at the historic high-grade Cam Copper Mine on the 100%-owned Miller Gold Property. Proceeds will also provide for follow-up of 2023 LiDAR and MMI soil survey results on the Company's 100%-owned Rosegrove Property, targeting alkaline intrusion-hosted gold mineralization. The Company will renounce CEE effective on or before December 31, 2023. The proceeds raised from the non-flow through component will also be used for non-critical minerals exploration work on the Miller Gold Property and for general working capital purposes.
