Highlights:

• Maiden inferred resource estimate for the Yarumalito Project of 1.24 Moz gold grading 0.58 g/t gold and 0.09% copper or 1.5 Moz gold equivalent grading 0.70 g/t gold equivalent (Table 1);
• The estimate furthers GoldMining's unique position of holding one of the largest global resource-stage gold portfolios among mid- and junior-tier mining companies;
• Yarumalito is GoldMining's third acquisition in the Mid Cauca Belt of central Colombia, which also hosts several multi-million ounce gold deposits owned by Zijin Mining, B2Gold and Anglogold Ashanti; and
• GoldMining's global aggregated mineral resource (Fig.1 and Table 2) now totals:
  •  10.5 Moz gold (13.4 Moz gold equivalent) in the measured and indicated categories; and
  •  13.7 Moz gold (16.4 Moz gold equivalent) in the inferred category.

Vancouver, British Columbia – May 5, 2020 – GoldMining Inc. (the "Company" or "GoldMining") (TSX: GOLD; OTCQX: GLDLF) is pleased to announce that it has completed a maiden mineral resource estimate for its 100% owned Yarumalito Gold-Copper Project (the "Yarumalito" or the "Project"), Antioquia, Colombia.

The mineral resource estimate was prepared by Global Mineral Resource Services of Vancouver, Canada and includes a pit constrained inferred resource of 66,271,000 tonnes grading 0.58 g/t gold (1,236,000 ounces) and 0.09% copper (129,262,000 pounds) or 0.70 g/t gold equivalent (1,502,000 ounces) using a 0.5 g/t gold equivalent cut-off.  See Table 1 below for information regarding the resource estimate.

Garnet Dawson, CEO of GoldMining, commented, "We are excited to announce this maiden resource for Yarumalito – another strategic acquisition our team identified and executed as part of our long-term plans of focused acquisitions in the Americas.  These acquisitions have uniquely positioned us with one of the largest global resource-stage gold portfolios among mid- and junior-tier mining companies.  While this has been a cornerstone of our strategy since inception, we see significant value in this position in the current environment of recent gold price improvements and decreasing worldwide gold discoveries.

Yarumalito is located within the same Miocene age gold belt that hosts advance-stage multi-million ounce gold deposits owned by Zijin Mining, B2Gold and Anglogold Ashanti; mineralization hosted on these projects is not necessarily indicative of the future mining potential of the Project.  Historic drilling at Yarumalito focused on delineating its gold-copper porphyry potential, however, in addition to intersecting long intervals of gold-copper mineralization, the drilling also intersected numerous high-grade, precious metal-rich base metal epithermal veins such as 33.75 g/t gold over 1.85 m intersected in drill hole YAR-11.  Future exploration programs will look to expand and upgrade the gold-copper porphyry mineralization at the Project, which remains open along strike and at depth, and to delineate the high-grade epithermal veins."

The Project

Yarumalito is located approximately 75 km southwest of the city of Medellin in the Department of Antioquia in Central Colombia and approximately 40 km south of GoldMining's La Mina Project.  The Project is accessible by paved road with nearby high-capacity power lines, water and labour.  Yarumalito is comprised of one concession for a total area of approximately 1,453 Ha. 

Exploration programs from 2008 to 2013 outlined several geophysical and geochemical anomalies across the property including the Obispo, La Suiza, Balastreras, Escuela, El Guaico and El Sucre targets.  Diamond drill programs (18,540 m in 55 holes) during that period primarily focused on the Balastreras-Escuela mineralization, which has a surface projection of approximately 1,700 m by 400 m and is intersected in drill holes and underground workings to a depth of 600 m.

Resource Estimate

The following table sets forth the mineral resource estimate for Yarumalito.

Table 1: Inferred resource statement¹ using a 0.5 g/t gold equivalent cut-off for the Yarumalito Gold-Copper Project, Colombia, Global Mineral Resource Services.

¹Mineral resources are not mineral reserves and do not have demonstrated economic viability.  There is no certainty that all or any part of the mineral resources will be converted into mineral reserves.  The estimate of mineral resources may be materially affected by environmental permitting, legal, title, taxation, sociopolitical, marketing or other relevant issues.

The Yarumalito deposit was modelled on a series of north-south cross-sections spaced 100 m apart from which a three-dimensional wireframe model was constructed for the mineralized zone at an approximate grade boundary of 0.1 g/t gold.  Diamond drill holes (50) totaling approximately 16,635 m were used to define the model.  High-grade gold values were capped at 9 g/t gold with 12 assays falling above this value.  Assay sample lengths were composited at 5.0 m.  Gold, copper and gold equivalent grades were interpolated into the block model in a single pass using inverse distance square weighting.  Individual blocks within the model measure 5 x 20 x 25 m in dimension.  For a grade to be interpolated into a block it was necessary that a minimum of two and a maximum of four composites be located within the volume of the search ellipse.  A maximum of one composite was allowed per drill hole to ensure that each block was informed by a minimum of two drill holes.  Average bulk density of 2.3 and 2.7 g/cm³ were used to convert block model volumes to tonnages for oxides and sulphides, respectively.  Gold equivalent grades were calculated based on the following formula:

AuEq = ((Au ppm*48.2) + (Cu ppm*0.006))/48.2

where 41.8 equals US$/gram for gold based on a gold price of US$1,500/ounce and 0.006 equals US$/ppm for copper based on a copper price of US$2.70/pound.  No allowance was made for metallurgical recoveries.  

The block model was validated in three ways: (i) visual comparison of block values with underlying drill hole composite values; (ii) comparison of descriptive statistics for the gold and copper block values with assay and composite values, and (iii) swath plots of gold equivalent composites, gold equivalent block grades and modeled tonnage.

Resources were classified as inferred because the drilling is relatively widely spaced and there has been limited metallurgical testwork.  Additional infill drilling and metallurgical test work would be required to confirm grade continuity and metallurgical recoveries, respectively to potentially upgrade the existing resource to indicated or measured categories.   

Reasonable prospects for eventual economic extraction were determined by reporting the resource within a conceptual pit shell.  The conceptual pit delineated resource is reported within a pit shell using an assumed gold price of US$1,500/oz, copper price of US$2.70/lb, pit slope of 45º, mining cost of US$2.00/t and processing cost of US$8.00/t.

Further details regarding the foregoing estimate, including the estimation methods and procedures, will be available in a Canadian National Instrument 43-101 Technical Report, which will be filed on SEDAR (www.sedar.com) under the Company's profile within 45 days of the date hereof.

Note on Mineral Resource Estimates

Inferred mineral resources have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility.  It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category.  Under applicable Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies.  It cannot be assumed that part or all of an inferred mineral resource will be upgraded to a mineral reserve.

The terms “mineral resource”, “measured mineral resource”, “indicated mineral resource”, “inferred mineral resource” used herein are Canadian mining terms used in accordance with NI 43-101 under the guidelines set out in the Canadian Institute of Mining and Metallurgy and Petroleum (the “CIM”) Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as may be amended from time to time.  These definitions differ from the definitions in the United States Securities & Exchange Commission (“SEC”) Industry Guide 7.  As such, information contained herein concerning descriptions of mineralization and resources under Canadian standards may not be comparable to similar information made public by U.S. companies in SEC filings.
