Drill Program Details and Geological Description
São Jorge lies 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, 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
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.
