GoldMining Reports Infill Core Sampling at São Jorge of 1.23 g/t Over 89.0 metres Including 3.62 g/t Gold over 15.0 Metres






GoldMining Inc. (TSX: GOLD) (NYSE American: GLDG) is pleased to announce initial infill assay results from the first two holes assayed as part of an ongoing fourteen hole infill core sampling program. The confirmatory assay program targets existing unsampled core intervals from previous drill programs at the 100% owned São Jorge property, located alongside regional highway BR-163 in the Tapajos region, Pará State, Brazil (see Figures 1-3 and Tables 1-2).


GoldMining initiated a preliminary economic assessment at São Jorge on completion of a Mineral Resource estimate (see June 1, 2021 news release). Initial PEA work has identified opportunities to better define and expand existing mineralization, and included this infill drill core sampling program. The Company intends to announce additional assay results from this program as it progresses.


Alastair Still, CEO of GoldMining, commented: “This is an exciting period for GoldMining as we advance several projects, including São Jorge, towards a preliminary economic assessment and as encountered here, the geologic results highlight the unrealized potential in our extensive portfolio of assets within the Americas. The assay results released today on previously unsampled core has identified potential additional mineralized intervals not previously recognized or sampled and helps support the grade and continuity of known mineralization at São Jorge.


Mr. Still continued: “Drill core collected by previous operators at São Jorge had not been continuously sampled, and we identified intervals with weak to moderate hydrothermal alteration in areas of unsampled core from earlier drill programs. Previous sampling programs focused on strongly altered zones based on a visual determination with limited or intermittent sampling in broader zones characterized by varying degrees of alteration and mineralization. These unsampled intervals are the target of our infill sampling program and will help better define limits of mineralization in certain areas of the deposit.”



  • Sampling has been completed on the initial 14 holes in phase 1 (see Figure 1)
  • More than 1,000 samples have been collected and are in varying stages of being shipped and processed by the assay lab
  • Results reported are from available assays for the first 2 holes
  • Hole SJD-058-06 includes previously unsampled intervals (see Figure 2 and Table 1):
    • 1.23 grams per tonne (“g/t”) gold over 89.0m from 157.0m to 246.0m, including:
    • 3.62 g/t gold over 14.0m from 157.0m to 171.0m;
    • 1.41 g/t gold over 7.0m from 179.0m to 186.0m;
    • 1.29 g/t gold over 5.0m from 194.0m to 199.0m;
    • 1.34 g/t gold over 10.0m from 203.0m to 213.0m; and
    • 1.04 g/t gold over 25.0m from 221.0m to 246.0m.
  • Hole SJD-058-06 correlates well with twinned hole SJD-058A-06; both holes were collared within metres of each other (see Table 2 and 3)
    • New results from SJD-058-06 include 1.23 g/t gold over 89.0m from 157.0m to 246.0m
    • Previous results from SJD-058A-06 include 0.92 g/t gold over 92.1m from 155.2m to 247.3m
  • Hole SJD-094-11 includes a previously unsampled interval (see Table 1 and Figure 3):
    • 0.68 g/t over 2.0 m from 58.0m to 60.0m


Results released today include an interval of weak to moderate alteration and mineralization within a previously unsampled interval from 50.0 to 70.0m in hole SJD-094-11 and extensive sections of SJD-058-06 from 140.0 to 259.0m which was drilled as a twinned hole next to SJD-058A-06 with the majority of the hole previously unsampled that contained extensive sections of strongly altered and mineralized materials that may be atypical of the remaining holes to be re-sampled. The costs for sample preparation and assaying for this program of work is being funded using cash on hand.
