GoldMining Options Up to 80% of the Boa Vista Project to Australian Mines Limited for Total Consideration of Up to $7 million

VANCOUVER, BC, July 1, 2025 /PRNewswire/ - GoldMining Inc. (the "Company" or "GoldMining") (TSX:GOLD) (NYSE:GLDG) is pleased to announce that its wholly-owned subsidiary has entered into a binding term sheet for an earn-in agreement (the "Earn-In Agreement"), pursuant to which, among other things, Australian Mines Limited (ASX:AUZ) ("AUZ") may acquire up to an 80% interest in the Company's Boa Vista Project ("Boa Vista" or the "Project"), located in the Tapajós Gold Province, Pará State, Brazil in consideration for aggregate cash and equity payments of up to $7 million¹, as described below. The Company presently owns an indirect 84.05% interest in the Project and, if the option is exercised in full, will retain a 20% interest at such time.

Alastair Still, CEO of GoldMining, commented: "We are pleased to announce this option agreement which positions GoldMining to unlock value from its Boa Vista Project. At the same time, the transaction will allow management to further focus its attention on advancing its key assets, such as the São Jorge Project, where the Company recently announced its largest drilling program to date. Boa Vista is not included within our disclosed global resource estimate, but it does contain numerous exploration targets and, following the full exercise of the proposed options, GoldMining will retain upside to Boa Vista through a retained interest, future staged earn-in and milestone payments and equity in AUZ as they advance the Project. We wish AUZ success with exploration and look forward to potential future benefits for both companies."

1. 1. $4,420,000 (AUD$5 million); and

Boa Vista Project

The Boa Vista Gold Project is located in the Tapajós Gold District, 350km south of the main regional city Itaituba, southwest Pará State, Brazil (see Figure 1). Access to the Boa Vista Gold Project from the cities of Itaituba or Novo Progresso is via highway BR-163 and artisanal mining roads, or via a 1.5-hour flight in a light aircraft from Itaituba. The Project comprises 3 exploration permits covering an area of approximately 9,201 ha (92 km²). GoldMining owns 84.05% of the Project with Majestic D&M Holdings, LLC owning the remaining 15.95%.

The Boa Vista property is underlain by granites, granodiorites and mafic volcanics. Bedrock surface exposures identify east-west, northwest and northeast striking shear structures containing quartz sulphide veinlets, silica breccia and stock works hosted in sericite and pyrite altered and foliated granite and mafic volcanic rocks. Mineralization at most prospects is considered to be mesothermal in nature, however at some of the prospects, vein textures suggest it may be epithermal style mineralization.

Coarse visible gold hosted in silica veined and brecciated rock was first discovered in surface outcrops at the VG1 prospect in 2010. Subsequent soil geochemical surveying has outlined a gold-in-soil anomaly trending to the west-northwest over 2 kilometres in length and up to 350 metres in width. Gold mineralization is associated with sericite, carbonate, silica and pyrite alteration associated with quartz stock work and brecciated granitic and mafic volcanic rocks.
