GoldMining Announces Closing of Flow-Through Financing and Commences Exploration at Yellowknife Gold Project

Flow-through share price of $1.34 represents ~25% premium to prior closing price; marks first exploration at the Project since 2012

Yellowknife Gold Project is Home to the Former Discovery Mine, Once One of the Highest-Grade Million Ounce Plus Past-Producing Gold Mines in Canada

VANCOUVER, BC, June 9, 2025 /PRNewswire/ - GoldMining Inc. (the "Company" or "GoldMining") (TSX:GOLD) (NYSE:GLDG) is pleased to announce that it has closed its non-brokered private placement of 373,135 common shares, which will qualify as "flow-through shares" within the meaning of the Income Tax Act (Canada) (each a "FT Share") at a price of $1.34 per FT Share for gross proceeds of $500,000 (the "Offering"). 

Alastair Still, CEO of GoldMining, commented:

"We are pleased to commence first exploration at our 100% owned Yellowknife Gold Project since 2012. The high-grade open pit mineral resource deposits contained within the project, with estimated gold grades in excess of 2.0 g/t, are distinct from the high-grade past-producing underground Discovery Mine which produced more than 1 million ounces of gold at average grade above 1 oz per short ton. High-grade past-producing underground mines have been the source for major gold discoveries in Canada in recent decades including at Red Lake, Kirkland Lake and Windfall Lake. We are extremely excited to be commencing a new chapter of modern gold exploration in the historically prolific and high-grade Yellowknife greenstone belt."

The Company will use an amount equal to the gross proceeds from the sale of the FT Shares to incur eligible "Canadian exploration expenses" that will qualify as "flow-through mining expenditures", as such terms are defined in the Income Tax Act (Canada) ("Qualifying Expenditures") in relation to the Company's Yellowknife Gold Project, on or before December 31, 2026. All Qualifying Expenditures will be renounced in favour of the subscribers effective December 31, 2025.

All securities issued under the Offering are subject to a hold period expiring four months and one day from the date of closing. The Offering remains subject to final acceptance of the Toronto Stock Exchange.

About the Yellowknife Gold Project

Located along approximately 100 kilometers of the Yellowknife Greenstone Belt, the Yellowknife Gold Project is comprised of five individual properties: Ormsby – Bruce, Nicholas Lake, Goodwin Lake, Clan Lake and Big Sky (see Figure 1). The Ormsby property hosts the Discovery Mine which operated from 1950 to 1969 with total production estimated to be 1,023,550 oz of gold from 1,018,800 short tons (st) of ore. The average production grade of slightly more than one oz of gold per st is generally considered the highest average grade of produced gold in the Yellowknife gold district, and one of the highest grade gold mines in Canada with production over one million ounces of gold. References to past production activity at the Discovery Gold Mine is provided for information purposes and is not intended to be indicative of future exploration at the Project.

The Yellowknife Gold Project deposits can be considered Archean Lode Gold deposits within an orogenic gold environment similar in age and style to mineralization documented throughout the Canadian Shield, including classic Canadian gold camps such as Red Lake, Timmins and Kirkland Lake. Gold occurs in favorable structural settings including areas of contrasting lithological competency, where brittle and ductile shearing provides the fluid pathways for deposition of quartz-carbonate veining as stockwork and lode gold quartz veining.

The Yellowknife Gold Project has been the focus of substantial drilling, underground development, and historic gold production. However, no additional exploration activities have been conducted on the Yellowknife gold project since 2012. Historic drilling completed on the property totals 1,061 holes for 231,609 meters.

The mineral resource estimate for the Yellowknife Gold Project is estimated to total 14.1 million tonnes ("Mt") at an average grade of 2.33 grams per tonne gold ("g/t Au") containing approximately 1,059,000 ounces ("oz") gold in measured and indicated categories and an additional 9.3 Mt at an average grade of 2.47 g/t Au containing approximately 739,000 oz Au is estimated in the inferred resource category. Mineral resources were estimated with an assumed gold price of $1,500 per ounce and metallurgical recovery of 90%. Most resources are open pit constrained resources with reasonable prospects of eventual economic extraction stated above a 0.50 g/t Au cut-off, with lesser quantities of underground resources estimated as contained within gold grade shapes above a 1.50 g/t Au cut-off based on a visual assessment of the continuity of grade.
