GoldMining Intersects 37 Metres Grading 2.26 g/t Gold Within Mineralized Corridor of 163 Metres Grading 1.02 g/t Gold at the São Jorge Project, Brazil

 

 

 

 

 

GoldMining Inc. (TSX: GOLD) (NYSE American: GLDG) is pleased to announce assay results from the first drill hole of its recently announced drilling program at the Company’s 100% owned São Jorge Project  in the Tapajós Gold district, Pará State, Brazil.

 

The program consists of approximately 1,000 metres of total proposed diamond core drilling and 3,000 m of power auger drilling. The objectives of the program include, among other things, to complete confirmatory drilling within and near the margins of the existing São Jorge gold deposit1, and test a reinterpretation of the structural controls on high-grade mineralization. Assay results for the first diamond drill hole have been received and are reported in this release.

 

Drill Hole SJD-120-24 highlights include:

  • 163 m at 1.02 grams per tonne gold from 44 m downhole depth, including higher-grade intersections:
    • 20 m at 1.37 g/t Au from 44 m depth;
    • 37 m at 2.26 g/t Au from 95 m depth;
    • 11 m at 1.00 g/t Au from 148 m depth;
    • 13 m at 1.35 g/t Au from 166 m depth; and
    • 12 m at 1.15 g/t Au from 195 m depth.

 

Tim Smith, Vice President of Exploration, commented: “We are pleased to announce the results from the first drilling at São Jorge in more than a decade. The results from this first drill hole are strong and we believe help demonstrate an extensive corridor of mineralization consisting of multiple intercepts of broad gold mineralization. These include some narrower higher-grade zones. Oriented diamond core drilling has successfully confirmed our thesis for the structural controls on mineralization within the deposit, which was the first objective of our multi-pronged drilling program. We expect that the improved geological model based on these intercepts will provide greater confidence in future mineral resource estimation. Additionally, we have commenced the auger drilling component of the program and forward to providing additional updates.”

 

Drill Program Details and Geological Description

 

São Jorge sits within the active and rapidly developing Tapajós Gold District (see Figure 1), which is estimated to have produced over 20 million ounces of gold historically from artisanal mining of surface deposits, according to the Brazil National Mining Agency. The Tapajós is home to Serabi Gold Plc.’s producing high-grade underground Palito Mine and G Mining Ventures Corp.’s brand new Tocantinzinho open pit mine, which recently commenced commissioning of its ore processing facility (see G Mining news release June 11, 2024).

 

São Jorge is located immediately adjacent to paved Hwy BR-163 and a new 138 kV powerline corridor tied into the district electrical grid recently constructed for Tocantinzinho. Exploration activities at São Jorge are operated from a permanent camp adjacent to the existing Deposit and just 3 kilometres from the highway.

 

The Company commenced drilling at São Jorge in May 2024 (see news release dated May 29, 2024). Structural analysis of historic mapping and oriented core from drilling by previous operators identified two principal vein/fracture orientations, the intersection of which produces a steeply plunging high-grade ‘shoot’ geometry. To test this interpretation, three infill (confirmatory) oriented core drill holes are planned within the known Deposit and near its margins (see Figure 2). This drilling, including results of the first hole contained in this news release could provide evidence for a better understanding of the controls on high-grade mineralization and optimization of the resource modelling methodology.

 

SJD-120-24 intersected numerous zones of gold mineralization starting in the saprolite zone near the surface and extending into bedrock (see Figure 3). Mineralization comprises fracture-controlled sulphide ± quartz veins, with the sulphides consisting of dominant pyrite with lesser chalcopyrite, along metre-scale northwest-southeast striking shear zones hosted within monzogranite and along a sheared footwall contact between monzogranite and syenogranite, which cumulatively defines the São Jorge high-strain corridor. Pyrite occurs as hairline stringers, disseminated grains and semi-massive pyrite in 3 – 5 cm thick veins. Better gold grades are related to a higher abundance of sulphide minerals, particularly thicker veins, and/or a higher density of semi-massive to massive pyrite veins. Figure 4 illustrates the strong visual nature of mineralization at São Jorge.

 

1 Additional information regarding the São Jorge Project, including existing resource estimates and historical work at the project, is set out in the technical report titled “São Jorge Gold Project, Pará State, Brazil: Independent Technical Report on Mineral Resources”, prepared for the Company and dated effective May 31, 2021, which is available under the Company’s profile at www.sedarplus.ca.

Data Verification

 

For this drill core sampling program, samples were taken from the NQ/HQ core by sawing the drill core in half, with one-half sent to SGS Geosol Laboratórios Ltda. in Brazil for assaying, and the other half of the core retained at the site for future reference. Sample lengths downhole were uniformly 1.0 m. SGS is a certified commercial laboratory in Vespasiano, Minas Gerais, Brazil, and is independent of GoldMining. GoldMining has implemented a quality assurance and quality control program for the sampling and analysis of drill core, including duplicates, mineralized standards and blank samples for each batch of 100 samples. The gold analyses were completed by FAA505 method (fire-assay with an atomic absorption finish on 50 grams of material).
