GoldMining Announces Resource Estimate for Almaden Gold Project, Idaho

Highlights:

• Resource estimate completed for the Almaden Project with 910,000 ounces gold grading 0.65 g/t gold in the indicated category and 160,000 ounces gold grading 0.56 g/t gold in the inferred category (Table 1);
  
  
• Historic drilling (70,234 m in 934 holes) and metallurgical test work completed on the Project, which hosts outcropping, low-sulphidation epithermal gold mineralization;
  
  
• Similar mineralization occurs at Hecla Mining's Hollister and Midas Mines in northern Nevada, and Integra Resources' Delamar and Florida Canyon development projects in southwest Idaho; and
  
  
• Increases GoldMining's global (11 projects, 5 countries) aggregated mineral resource (Fig. 1 and Table 2) to:
  
  
• 11.4 Moz gold (14.3 Moz gold equivalent) in the measured and indicated categories; and
  
  
• 13.8 Moz gold (16.6 Moz gold equivalent) in the inferred category.

VANCOUVER, June 3, 2020 /PRNewswire/ - GoldMining Inc. (the "Company" or "GoldMining") (TSX: GOLD; OTCQX: GLDLF) is pleased to announce a mineral resource estimate for its 100% owned Almaden Gold Project ("Almaden" or the "Project") located in Idaho. 

The mineral resource estimate was prepared by Global Mineral Resource Services of Vancouver, Canada and includes a pit constrained indicated resource of 43,470,000 tonnes grading 0.65 g/t gold (910,000 ounces) and an inferred resource of 9,150,000 tonnes grading 0.56 g/t gold (160,000 ounces) using a 0.3 g/t gold cut-off.

Garnet Dawson, CEO of GoldMining, commented:  

"Almaden's near surface resource is mostly in the indicated category (approximately 85%), which facilitates potential economic studies without the major expense of infill drill programs to upgrade inferred resources to measured and indicated categories. 

Future exploration programs will look to model metallurgical recoveries across the deposit along with additional metallurgical test work to determine potential processing scenarios before undertaking a potential future preliminary economic assessment.  Exploration potential and upside for future resource growth is believed to be high given the shallow average depth of existing drilling of approximately 75 metres.

Together with our resource estimate for our Yarumalito project, the Almaden resource estimate marks the second resource estimate completed by our team in 2020.  This is a testament to our team's continued dedication to our long-term strategy and builds on the value generated by our recent acquisitions."

Almaden Project

The Almaden Project covers approximately 1,724 Ha and is located 140 km by road north of Boise and 24 km east of Weiser in Washington County, Idaho.

Almaden is one of several low-sulphidation epithermal gold deposits related to the Northern Nevada Rift that includes Hecla Mining Company's Hollister and Midas Mines in northern Nevada and Integra Resources Corp.'s Delmar and Florida Canyon projects in southwest Idaho.

Gold mineralization is associated with intense silicification and argillic alteration that measures approximately 1,900 m long by 500 m wide by 150 m thick.  The deposit was intermittently drilled (70,234 m in 934 holes) from 1980 to 2012 by several companies including Homestake and Amax Gold Inc.

Resource Estimate

The following table sets forth the mineral resource estimate for the Almaden Gold Project, which has an effective date of April 1, 2020. 

Table 1: Almaden Resource Estimate¹ using a 0.3 g/t gold cut-off.

The Almaden deposit was modelled on a series of east-west cross-sections spaced approximately 30.5 m (100 ft) apart from which a three-dimensional wireframe model was constructed for the mineralized zone at an approximate grade boundary of 0.035 g/t gold.  Assay samples (37,734) within the mineralized solid were predominantly (95%) 1.5 m (5 ft) in length and therefore all samples were composited at 1.5 m (5 ft) for resource estimation.  Variography was used to model the grade continuity and to determine the search ellipse orientations and dimensions for interpolation.  Ordinary kriging was used to estimate gold grades in a single pass into blocks measuring 5.2 m (20 ft) by 9.1 m (30 ft) by 3.0 m (10 ft) in dimension.  For a grade to be interpolated into a block it was necessary that a minimum of two and a maximum of six composites be located within the volume of the search ellipse.  A maximum of one composite was allowed per drill hole to ensure that geological continuity was demonstrated by requiring that each block was informed by a minimum of two drill holes.  The estimation process calculated a volume/block for each block within the constraining grade shell.  Average bulk density of 2.50 g/cm³ (100 measurements) was used to convert block model volumes to tonnages.

The block model was validated in three ways:

Resources were classified as indicated and inferred based on drill hole spacing.

Reasonable prospects for eventual economic extraction of the resource were met 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, pit slope of 45º, mining cost of US$2.25/t and processing cost of US$10.00/t.

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

Quality Control – Quality Assurance Program

The above resource estimate was based on drilling programs completed by previous operators.  The drill programs incorporated control samples including blanks, duplicates and standards as part of their Quality Control – Quality Assurance Program.  The control samples from the drill programs have been reviewed and verified by the Qualified Persons (as defined herein) and the assay results were deemed suitable for resource estimation.

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.
