What announcement did Minrex Resources (ASX:MRR) make regarding its Serbian project?

Minrex Resources (ASX:MRR) has officially commenced its fully funded 2026 drilling programme at the Barje Deposit. Rigs have been mobilised by regional contractor Drillex International to initiate a comprehensive, 7,000-metre exploration campaign.

Why does the 2026 drilling programme matter for Minrex Resources (ASX:MRR) investors?

The Barje Deposit is the cornerstone asset of Minrex Resources' (ASX:MRR) flagship Tlamino Gold Project in southern Serbia. This 7,000-metre operation serves as the company's first major operational catalyst of the year, designed to upgrade resource confidence and underpin upcoming economic evaluations.

What is management trying to achieve with this drilling campaign?

Management is looking to methodically convert the Barje Deposit's existing inferred mineral resources into the higher-confidence indicated category.

What historical drilling metrics make the Barje Deposit attractive to traders?

Prior exploration at the Barje Deposit yielded exceptional high-grade, shallow intercepts. Standout historical results include 30 metres at 5.45 grams per tonne (g/t) gold and 11 g/t silver from 74 metres (including a zone of 6 metres at 14.17 g/t gold), and 38.2 metres at 3.68 g/t gold and 158 g/t silver from a shallow depth of 16.8 metres.

How risky is Minrex Resources (ASX:MRR) stock after this news?

While the drilling programme is fully funded, Minrex Resources (ASX:MRR) remains a highly speculative, small-cap exploration company. Mineral resource conversion is never guaranteed, and there is inherent geological risk regarding whether the new assay results will match the high grades of historical intercepts.

Minrex Resources (ASX:MRR) commenced its fully funded 2026 drilling programme at the Barje Deposit, the cornerstone asset of its flagship Tlamino Gold Project in southern Serbia.

Regional contractor Drillex International has mobilised rigs and initiated a comprehensive, 7,000-metre drilling campaign.

The operation is designed to methodically convert existing inferred mineral resources into the higher-confidence indicated category, laying the crucial groundwork to underpinning an updated economic study for the high-grade asset.

Investors are closely watching the development, given the exceptional historical intercepts previously reported from the Barje Deposit.

Prior results highlighted include a standout intercept of 30m at 5.45 grammes per tonne gold (Au) and 11 g/t silver (Ag) from 74m, which featured an ultra-high-grade zone of 6m at 14.17 g/t gold.

Other historical results include 38.2m at 3.68 g/t gold and 158 g/t silver from just 16.8m, underscoring the shallow, robust nature of the mineralisation.

The drilling campaign marks the first major catalyst in a sequence of planned milestones for the company this year.

Shareholders can anticipate a steady stream of news flow, with initial laboratory assays targeted for delivery in the September quarter.

Minrex Resources aims to deliver an updated mineral resource estimate alongside a refreshed scoping study, both targeted for completion around year-end.
