Minrex Finds High-Grade Link Across Barje's Modelled Gap

Central Barje Drilling Rewrites the Geological Model

Minrex Resources Limited (ASX:MRR) has found its strongest Barje mineralisation in the one area where the historical model expected the least. Five of nine diamond holes drilled through the central zone of the Barje deposit in Serbia returned thick, high-grade intersections across a corridor previously treated as a low-grade saddle between two separate mineralised zones.

The standout result came from BAR046, which intersected 36 metres at 5.85 g/t gold equivalent from 47 metres, including 4.2 metres at 15.67 g/t and a further 14 metres at 7.74 g/t. Minrex describes it as the widest and highest-grade intersection drilled at Barje to date. The company estimates the 36-metre downhole interval represents about 32 metres of vertical thickness.

Four Holes Trace a Continuous High-Grade Corridor

BAR047 returned 18.3 metres at 4.87 g/t AuEq from 57.7 metres, including 6.5 metres at 8.53 g/t. BAR050 delivered 17.5 metres at 5.22 g/t from just 14.4 metres, with an 8.2-metre core grading 7.60 g/t. BAR045 added 10.2 metres at 4.16 g/t from 67 metres, including 5.2 metres at 7.31 g/t.

Together, BAR045, BAR046, BAR047 and BAR050 form what Minrex interprets as a continuous line of domain-grade or better mineralisation across the historically modelled gap. A fifth hole, BAR043, returned a broader but lower-grade 24.6-metre interval at 2.39 g/t AuEq from 50 metres, including 9.2 metres at 4.87 g/t.

The results matter because they suggest Barje's eastern and western high-grade zones may be connected through the centre of the deposit rather than existing as two isolated bodies. That remains an exploration interpretation, not a new resource estimate, and the announcement says the current results are not captured in the existing model.

Resource and Mine Planning Implications Remain Unproven

Barje's 2021 estimate contains 670,000 ounces of gold equivalent at 2.9 g/t AuEq, but it is a foreign estimate reported under NI 43-101 and is not a JORC-compliant Mineral Resource. Its high-grade breccia component accounts for 470,000 ounces at 4.7 g/t AuEq. Minrex says the newly identified central mineralisation could add volume to that high-grade envelope and potentially improve near-surface head grades and strip ratios in any future mine plan.

Those economic benefits are forward-looking. The AuEq figures use assumed gold and silver prices of US$3,300 an ounce and US$45 an ounce respectively, alongside 84% recoveries for both metals based on prior testwork. More assays are pending from other holes in the broader drilling programme, while the rig has moved to step-out work along strike. Minrex is also considering more central-zone drilling before finalising its maiden JORC (2012) Mineral Resource Estimate, scheduled for next quarter.
