DESIGNATED NEWS RELEASE

VANCOUVER, BC, Jan. 23, 2023 /PRNewswire/ - GoldMining Inc. (the "Company" or "GoldMining") (TSX: GOLD) (NYSE American: GLDG) is pleased to announce an updated Mineral Resource estimate ("MRE") on its 100% owned La Mina Project located in the Middle Cauca Porphyry Belt, Antioquia, Colombia.  The MRE includes a maiden resource estimate on the La Garrucha deposit which incorporates drilling completed by the Company in 2022.

Highlights: 

La Garrucha – New Discovery

• Indicated Mineral Resources of 0.20 million ounces (Moz) gold equivalent (AuEq) at 0.84 g/t AuEq (7.4 million tonnes (Mt) grading 0.65 g/t gold, 3.14 g/t silver and 0.11% copper) (see Table 1); and
• Inferred Mineral Resources of 1.02 Moz AuEq at 0.72 g/t AuEq (44.1 Mt grading 0.55 g/t gold, 2.46 g/t silver and 0.10% copper) (see Table 1).

La Mina – Combined MRE

• Indicated Mineral Resources of 1.15 Moz AuEq at 1.06 g/t AuEq, an increase of 16% in ounces and decrease in grade of 3% from 2022 (33.8 Mt grading 0.73 g/t gold, 2.08 g/t silver and 0.21% copper) (see Table 1); and
• Inferred Mineral Resources of 1.45 Moz AuEq at 0.80 g/t AuEq an increase of 215% in ounces and decrease in grade of 24% from 2022 (56.2 Mt grading 0.58 g/t gold, 2.32 g/t silver and 0.14% copper) (see Table 1).

Alastair Still, CEO of GoldMining, commented, "We are extremely pleased that the Company's first exploration drilling program at La Mina has identified a significant discovery at the La Garrucha deposit that has added over 1,000,000 gold equivalent ounces of estimated Inferred Resources and 200,000 gold equivalent ounces of estimated Indicated Resources to an already robust Mineral Resource estimate on our La Mina project. This exciting discovery has exceeded our expectations and builds upon the positive economics set out in our 2022 Preliminary Economic Assessment, which was based on the prior resource estimate for the project, exclusive of La Garrucha. Throughout, our team has maintained high standards of sustainable exploration and demonstrated our commitment to safety, effective stakeholder engagement and environmental stewardship.

With all-inclusive direct drilling costs by the Company at La Garrucha of under US$1.2 million for our recent program, this discovery was made at a very efficient cost per ounce of estimated resource and exemplifies our strategy and progress of unlocking value from our portfolio of gold and gold-copper assets while maintaining a peer-leading balance sheet."

Tim Smith, Vice President Exploration of GoldMining, commented, "The updated Mineral Resource estimate at La Garrucha represents an unqualified success for the Company in applying its strategy of identifying the best value accretion opportunities within our diverse portfolio of gold and gold-copper resource assets located throughout the Americas.  From inception to execution, the drill program was expertly managed by our team in Colombia and the results demonstrate both the quality and further potential for additional discovery within the La Mina porphyry gold-copper mineral system.  On the strength of this updated Mineral Resource estimate, the Company now looks forward to updating the La Mina Preliminary Economic Assessment (PEA) which we expect to complete on or around mid-2023."

Notes:

1.  The Mineral Resource for La Mina is an in-pit constrained resource calculated using a Whittle-Pit algorithm with "reasonable prospects of eventual economic extraction" using the following assumptions: Metal prices of US$1,700/oz Au, US$21/oz Ag and US$3.50/lb Cu; Royalty of 6% NSR, inclusive of government royalties; Pit slopes are 50 degrees; and Mining, processing and G&A costs were used to calculate cut-off of 0.30 g/t Au.

2.  Metallurgical recoveries are: 82% for Au, 84% for Cu, and 30% for Ag.

3.  Gold-equivalent grades were calculated using the following formula: AuEq = Au (g/t) + [Cu(%) x {Cu Price/Au Price} x 22.0462 x 31.1035] + [Ag (g/t) x {Ag Price/Au Price}].

4.  Mineral resources are classified as Indicated Resources and Inferred Resources and are based on the 2014 CIM Definition Standards on Mineral Resources and Mineral Reserves.

5.  Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources will be converted to Mineral Reserves. The estimate of mineral resources may be materially affected by environmental permitting, legal, title, taxation, sociopolitical, marketing or other relevant issues.

6.  Numbers may not add due to rounding.

The La Mina property consists of two concession contracts and two concession contract applications covering 3,210 hectares located in the Department of Antioquia, Republic of Colombia, some 51 km SW of Medellin. The MRE for La Mina incorporates the La Cantera, La Garrucha and Middle Zone porphyry deposits located within 1 km of each other. 

From late March to mid-August 2022, GoldMining completed a diamond core drilling program comprising five drill holes for 3,485 m at the La Garrucha deposit, a porphyry mineral system which measures over 400 m in strike length by 300 m in width and to at least 775 m below surface where it remains open. Gold and copper mineralization in the La Garrucha porphyry intrusive complex is accompanied by strong potassic alteration, characterized by secondary potassium feldspar and biotite, disseminated and vein magnetite, quartz stockwork veining and both vein-hosted and disseminated sulphides that include pyrite, chalcopyrite and lesser bornite. Lithological, alteration and structural logging of both the new core and re-logging of historic core was completed to compile a three-dimensional geological model. 

The MRE disclosed herein for the La Mina Project was prepared by Scott Wilson, C.P.G., of Resource Development Associates Inc. and has an effective date of December 20, 2022.  The MRE updates and replaces the prior MRE of the Company contained in its technical report titled, "NI 43-101 Technical Report and Preliminary Economic Assessment: GoldMining Inc., La Mina Project, Antioquia, Republic of Colombia" dated effective January 12, 2022.

Notice to Readers

Disclosure regarding Mineral Resource estimates included herein have been prepared by the Company in accordance with NI 43-101. NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for public disclosure by issuer of scientific and technical information concerning mineral projects. NI 43-101 differs significantly from the disclosure requirements of the United States Securities and Exchange Commission ("SEC") generally applicable to U.S. companies subject to the SEC's disclosure requirements. For example, the terms "Indicated Mineral Resource" and "Inferred Mineral Resource" are defined in NI 43-101 by reference to the guidelines set out in the CIM Definition Standards on Mineral Resources and Mineral Reserves. Shareholders resident in the United States are cautioned that while terms are substantially similar to "indicated mineral resources" and "inferred mineral resources" as defined by the SEC, there are differences in the definitions and standards under applicable SEC Rules and NI 43-101. Accordingly, there is no assurance any mineral resources that the Company may report as "Indicated Mineral Resources" and "Inferred Mineral Resources" under NI 43-101 will be the same as the reserve or resource estimates prepared under rules applicable to United States domestic issuers. Investors are cautioned not to assume that any part or all of mineral resources will ever be converted into reserves. Pursuant to CIM Definition Standards, "Inferred mineral resources" are that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Such geological evidence is sufficient to imply but not verify geological and grade or quality continuity. An inferred mineral resource has a lower level of confidence than that applying to an indicated mineral resource and must not be converted to a mineral reserve. However, it is reasonably expected that the majority of inferred mineral resources could be upgraded to indicated mineral resources with continued exploration. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource is economically or legally mineable. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measures.
