G50 Corp (ASX:G50) has confirmed shallow gold-silver and gallium mineralisation over 1.8km at its Golconda Project in Arizona, US, with final results from the 2025–2026 drilling program.
The company completed nine holes, including four reverse circulation (RC) holes at the Golden Eagle target.
Results include 21.3m @ 3.72 grams per tonne gold (Au) and 28.76g/t silver (Ag) from 36.6m in hole GRC54, including 10.7m @ 7.25g/t Au and 49.82g/t Ag from 36.6m.
Hole GRC51 returned 13.7m @ 5.42g/t Au and 112.58g/t Ag from 64.0m, and 3m @ 4.29g/t Au and 814g/t Ag from 10.7m.
Drilling also confirmed widespread gallium mineralisation, with intercepts including 213m @ 17.6g/t gallium (Ga) from surface in GRC47 and 450m @ 19.8g/t Ga from 1.1m in core hole GDD08.
Managing Director Mark Wallace says the program has confirmed mineralisation hosted within a ‘district-scale structure’ over 1.8km and widths up to 400m.
“Drilling at Golconda comprising a total of 54 RC, and nine core holes has now confirmed significant gold, silver, and gallium mineralisation hosted within a district-scale structure — referred to as the Tub Structural Zone — over a distance of 1.8km and widths of up to 400m,” Wallace says.
The Tub Structural Zone hosts multiple sub-parallel quartz-sulphide veins containing gold, silver, and base metals within a broad alteration halo of gallium-bearing minerals.
Mineralisation starts at surface and extends to 400m depth, remaining open at depth and along strike.
Two RC holes tested shallow extensions of the Green Linnet Vein, intersecting 4.6m @ 1.22g/t Au and 8g/t Ag from 70.1m in GRC49, and 7.6m at 1.31g/t Au, 20.3g/t Ag, and 0.4% zinc from 85.3m in GRC50.
Golden Eagle represents the northwestern extent of mineralisation along the Tub Structure, located 250m northwest of previously reported holes. Results demonstrate continuity across the 1.8km strike length.
G50 Corp plans to incorporate results into an updated geological model and generate new drilling targets for parallel veins.
Core drilling is scheduled for December 2026, with baseline studies to support permitting for an exploration plan of operations also planned.
