Selinsing Gold Mine: Monument drill assays signal expansion upside

Monument Mining Limited announced results from an additional 23 drill holes under its Selinsing mine expansion program, reporting multiple high-grade gold assay intervals from the Buffalo Reef and Felda areas. The company highlighted that the new data support potential resource additions outside current Life of Mine (LOM) and expanded pit shells.

According to the release, the Stage 1 and Stage 2 programs have completed 123 holes for 17,136.1 metres, with assay results received for the 23 reported holes. Notable intercepts include intervals such as 3.0m @ 5.66 g/t Au and 1.1m @ 13.9 g/t Au in MBRDD628, 15.5m @ 2.61 g/t Au (incl. 6m @ 5.62 g/t) in MBRRC632, and 10.1m @ 4.68 g/t Au in MBRDD627. The company said these intersections show continuity with previously modeled mineralized domains.

Market implications center on the potential for a material uplift in mineral resources if further modeling converts inferred material and pending assays confirm continuity. Monument’s recent fiscal updates show Selinsing production contributing meaningful revenue and cash flow, which could bolster the company’s capacity to fund follow-up drilling and studies—factors investors typically value when assessing mid-tier gold producers.

The drilling targeted gap zones between Buffalo Reef Central pits (BRC2/BRC3 and BRC3/BRC4) and down-dip extensions below planned pit shells; several holes intersected mineralization beneath both current LOM and expanded pit shells, indicating potential for resource expansion and future pit re-optimization. Monument has previously outlined its phased drilling plan for Selinsing and Buffalo Reef/Felda as part of a broader strategy to test extensions outside defined pit shells.

Key near-term milestones for market participants are receipt of remaining assays, incorporation of new data into updated resource models, and any subsequent technical studies that could convert resources to reserves or support tenement extensions. Monument expects to receive all drilling assays by June 2026; forthcoming technical updates will be decisive for the company’s mine-life outlook and for how the market re-prices MMY relative to gold-sector peers.
