VANCOUVER, BC, Sept. 23, 2021 /PRNewswire/ - GoldMining Inc. (the "Company" or "GoldMining") (TSX: GOLD) (NYSE American: GLDG) is pleased to announce the completion of updated Mineral Resource estimates ("MREs") for four of the most significant properties owned by the Company. The updates included new pit constrained Mineral Resource estimates on each of the 100% owned Titiribi, Whistler, La Mina and São Jorge properties in addition to an amended technical report for the Company's Yellowknife Gold project. The technical reports are available for review under the Company's profile on SEDAR (www.sedar.com) and on the Company's website (www.goldmining.com).

Alastair Still, CEO of GoldMining, commented: "We are very pleased to have completed a foundational de-risking exercise by updating Mineral Resource estimates on four of our key properties. These properties, combined with an amended Mineral Resource estimate on Yellowknife Gold collectively represent approximately 84% of the Company's total Measured and Indicated Mineral Resources of 16.24 million gold equivalent ounces and approximately 74% of the Company's total Inferred Mineral Resources of 16.17 million gold equivalent ounces (see Table 1)."

Mr. Still continued: "Updating and modernizing the MREs on key properties helps lay the foundation for the next stage of further advancing the projects. We are currently progressing with preliminary economic assessments ("PEAs") at our Yellowknife Gold project in Northwest Territories, Canada, São Jorge in Pará State, Brazil and La Mina in Antioquia, Colombia which we expect to have completed in the next six months. We look forward to sharing results of the PEAs and other activities as we continue to unlock value from our extensive portfolio of assets within favourable mining jurisdictions located entirely within the Americas."

Notice to Readers

Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. There is no certainty that any part of the Mineral Resources estimated will be converted into a Mineral Reserves estimate. 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. These definitions differ from the definitions in the disclosure requirements promulgated by the SEC. Accordingly, information contained herein or in the Company's descriptions of its projects may not be comparable to similar information made public by U.S. companies reporting pursuant to SEC disclosure requirements.
