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
The program consists of approximately 1,000 metres ("m") 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 (the "Deposit"), 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 (g/t) gold (Au) 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.
Drill Program Details and Geological Description
São Jorge sits within the active and rapidly developing Tapajós
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
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.
