GoldMining Inc. announced the results of an updated Mineral Resource Estimate ("MRE") on its 100% owned Whistler Project ("Whistler") in south central Alaska, U.S.A. consisting of resource estimates for the Whistler, Island Mountain and Raintree West gold-copper deposits with an effective date of June 11, 2021. Whistler Updated Resource Highlights: Indicated Mineral Resources of 1.94 million ounces gold, 8.33 million ounces of silver and 422.0 million pounds of copper (118.2 million tonnes grading 0.51 g/t gold, 2.19 g/t silver and 0.16% copper); Inferred Mineral Resources of 4.67 million ounces gold, 16.06 million ounces silver and 711.4 million pounds of copper (317.0 million tonnes gradin 0.46 g/t gold, 1.58 g/t silver and 0.10% copper); Compared to the prior reported estimate completed in 2016, Indicated Mineral Resources for gold, copper and silver have increased by 9.9%, 23.0% and 35.9% respectively; Compared to the prior estimate reported in 2016, Inferred Mineral Resources for gold have increased 0.9%, and for copper and silver have decreased by 0.3% and 29.0% respectively; The MRE utilizes pit shells to constrain resources at the Whistler, Island Mountain and Raintree West gold-copper deposits, as well as an underground potentially mineable shape to constrain the resource estimate for the deeper portion of the Raintree West deposit; The total Whistler Project area comprises a database of 250 drill holes totaling more than 70,000 metres with 182 drillholes and 53,202m of assayed length within the three deposit block models. The estimate has been updated with new metal prices of $1,600/oz gold price, $3.25 copper and $21/oz silver, updated recoveries, smelter terms, costs, and geologic modelling with drilling and exploration work completed prior to 2016. GoldMining is evaluating potential exploration activities to better define and expand existing mineral resources. The new MRE is constrained by an optimized pit shell that incorporates updated operating costs and metal price assumptions that factor price increases since 2016. This work builds upon the staged approach of advancing portfolio of gold and gold-copper projects throughout the Americas such as the previously announced initiation of Preliminary Economic Assessments ("PEA") on Yellowknife, La Mina, and São Jorge Projects in Canada, Colombia, and Brazil respectively. The estimate of Mineral Resources may be materially affected by environmental permitting, legal, title, taxation, sociopolitical, marketing or other relevant factors. The QP is not currently aware of any known environmental, permitting, legal, title-related, taxation, socio-political, marketing or other relevant issue that could materially affect this MRE. The Whistler Project is a gold-copper exploration project located in the Yentna Mining District of Alaska, approximately 150km northwest of Anchorage and comprises 304 State of Alaska mining claims covering an aggregate area of approximately 17,159 hectares. A base camp and gravel airstrip for wheel-based aircraft is established for field programs. The Whistler and Raintree West deposits are connected to the camp and runway by an access road and the Island Mountain deposit is located 23 km south of the camp and access is by helicopter. The Whistler Project is underlain by a volcano- sedimentary sequence (Jura-Cretaceous Kahiltna Assemblage) that has been intruded by the Late Cretaceous Whistler Intrusive Suite with associated gold-copper porphyry and epithermal mineralization, and the Late Cretaceous to Paleocene Composite Intrusive Suite with associated intrusion-related gold mineralization. Immediately west of the Whistler Project is the Estelle Gold Project of Nova Minerals Limited, who recently reported an Inferred JORC Mineral Resource Estimate for their Korbel Main deposit. The Mineral Resource Estimate (MRE) disclosed herein was prepared by Sue Bird, P.Eng., of Moose Mountain Technical Services and has an effective date of June 11, 2021. Ordinary kriging was used to estimate gold, copper and silver. Capping of each metal has been employed based on interpolation domains statistics and cumulative probability plots to limit high grade outliers. Outlier restriction has also been employed to restrict the volume of influence of high grades within each deposit and domain.
