GoldMining Inc. Commences Exploration Drilling at

São Jorge Project, Brazil

Vancouver, British Columbia – May 12, 2025 – GoldMining Inc. (the "Company" or "GoldMining") (TSX:

GOLD; NYSE American: GLDG) is pleased to report that it has commenced drilling with two diamond core

drills in support of the previously announced exploration program at its 100% owned São Jorge Project

("São Jorge" or the "Project") in the Tapajós gold district, Pará State, Brazil. The program, which was

commenced on time and on budget is the most extensive exploration program initiated by the Company to

date.

Highlights:

• Commenced drilling at São Jorge with two diamond core drills

• Approximately 500 metres completed of the planned campaign of up to 5,000 metres

• Also an airborne Lidar survey was initiated to provide high-resolution images of topography and

structural geological information

• Additional planned activities include extensive auger drilling and soil sampling programs, and

ground geophysical surveys including Induced Polarisation ("IP")

• Excellent infrastructure, including an existing 35-person camp and easy access to paved highway

and grid power, has helped facilitate a rapid ramp-up of exploration activities

• Building on the Company’s strong safety and sustainability culture, the excellent safety record to

date is testament to the Company’s investment in safety and environmental training , which is

provided for all employees and contractors and optimizes other production metrics

Alastair Still, Chief Executive Officer of GoldMining, commented: "Our local team in Brazil has done a

tremendous job successfully initiating the most extensive drilling program to date at our São Jorge Project

with zero reportable safety and environmental incidents . Following a successfully executed 2024 drilling

campaign, which utilized one diamond coring drill, we have doubled coring capacity this field season with

two drills to perform the 2025 exploration campaign.

We look forward to reporting results from this systematic exploration program that is targeting expansion of

the São Jorge deposit, which remains open along strike to the northwest and southe ast, and to test new

targets outside of known areas of mineralization extending over a 12 km x 7 km geochemical footprint within

our 100%-owned regional scale property exceeding 46,000 hectares in size.”

2025 São Jorge Exploration Drilling

The Company's 2025 core drilling program utilizes two drill rigs from the same contractor it appointed to

conduct the 2024 drilling program, which was completed efficiently and with no safety or environmental

incidents (see Figure 1).

The drilling comprises fences of drill holes targeting the potential extension of the deposit's known limits

along the trend to the northwest and southeast (see Figure 2). Pending results, the Company may

undertake further step-out drill fences along strike to continue testing the prospective structural corridor.

About São Jorge

The São Jorge Gold Project is located in the Tapajós gold district in the south-central portion of the Amazon

Craton. The São Jorge mineral deposit (the "Deposit") is a granite-hosted, intrusion-related gold deposit,

similar to the Tocantinzinho gold deposit located approximately 80 km northwest of São Jorge. Exploration

activities carried out by the Company over the past two years ha ve successfully delineated several new

exploration targets comprising gold ± copper ± molybdenum ± silver soil geochemical anomalies , which

cumulatively outlines a potential large mineral system defined by a 12 km x 7 km geochemical footprint

surrounding the Deposit (see news releases dated March 18, 2025 and April 14, 2025).
