GoldMining Confirms Additional Mineralization at the São Jorge Project, Brazil, Including 19 Metres Grading 1.24 g/t Gold






GoldMining Inc. (TSX: GOLD) (NYSE American: GLDG) is pleased to announce additional assay results from the previously announced drilling program at the Company’s 100% owned São Jorge Project in the Tapajós gold district, Pará State, Brazil. The diamond core drilling component of the program, which is now complete, consisted of 1,077 metres. The objectives of the program included confirmatory drilling within and near the margins of the existing São Jorge gold deposit, as well as exploratory drilling approximately one kilometre away from known mineralization in an area with no previous drilling.


Assay results for two additional diamond drill holes (SJD-121-24 and SJD-122-24) have been received, which combined with the previously released hole, SJD-120-24 (see news release dated June 18, 2024), have successfully completed the confirmatory component of drilling within and near the margins of the Deposit.


Highlights include:

  •  SJD-122-24:
    •  19 m at 1.24 grams per tonne (g/t) gold (Au) from 61 m depth, including:
      • 7 m at 2.98 g/t Au from 68 m depth.
  •  SJD-121-24:
    •  18 m at 0.70 g/t Au from 86 m depth, including:
      • 8 m at 1.14 g/t Au from 88 m


Tim Smith, Vice President of Exploration, commented: “We are pleased to announce additional results from the recently completed drilling at São Jorge. The results from these two drill holes near the western known extents of the main São Jorge deposit further help to delineate the corridor of mineralization consisting of multiple intercepts of gold mineralization and indicating a possible en echelon array of mineralized veins within the broader São Jorge high-strain corridor. Further oriented diamond core drilling will help to model these zones and improve resource confidence. Additionally, our auger drilling program is proceeding to map bedrock lithology and collect geochemical samples of the in situ saprolite located beneath broad surface soil anomalies, and it is anticipated this will help define vectors towards possible new zones of bedrock-hosted mineralization. We look forward to providing further updates from the São Jorge drilling program.


Drill Program Details and Geological Description


São Jorge lies 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 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, which ties into the district electrical grid recently constructed for Tocantinzinho. Exploration activities at São Jorge are operated from a permanent camp near 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) and released results of the first confirmatory drill hole SJD-120-24 (see news release dated June 18, 2024) with an interval of 163 m at 1.02 g/t Au, including 37 m at 2.26 g/t Au (see Figure 2).


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. Higher 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 (see Figure 3).


SJD-121-24 and SJD-122-24 provided additional infill drilling in the western portion of the Deposit to support potential future resource interpolation and classification (see Figure 4). Drilling intersected multiple zones of mineralization hosted within the São Jorge high-strain corridor. SJD-122-24 demonstrated strong mineralization directly along strike of the main Deposit. SJD-121-24 intersected several zones of mineralization north of the established Deposit strike direction, representing possible en echelon northwest stepping of mineralized structures within a large low-grade envelope associated with the broader São Jorge high-strain corridor. See Tables 1 and 2 below for further information regarding the drilling.

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).
