Orbminco Hits High-Grade Gold in Majestic North Infill Drilling, Resource Upgrade Looms

Infill Drilling Confirms Strong Shallow Gold Mineralisation

Orbminco Limited (ASX:OB1) has reported compelling high-grade gold results from the first batch of assays in its 27-hole reverse circulation (RC) drilling campaign at the Majestic North Gold Project in Western Australia. The initial 10-hole Resource Development infill program targeted the shallow optimised pit shell and returned standout intercepts including 2 metres at 17.69 g/t Au from 19 metres and 1 metre at 8.05 g/t Au from 20 metres. Nine out of ten holes surpassed the 0.5 g/t gold cutoff, with mineralisation commencing from approximately 19 metres downhole, reinforcing the potential for near-surface extraction.

Resource Upgrade Potential Hinges on Pending Assays

While these early results bolster confidence in the existing Mineral Resource, assays from the remaining 17 holes; comprising 16 structural junction tests and one deeper basement hole; are still awaited. These tests are critical as they directly probe geological structures interpreted to control a previously reported higher-grade domain of 249,000 tonnes at 2.42 g/t Au, containing around 19,300 ounces. The company anticipates that integrating the full dataset could enhance resource classification, improve grade continuity, and potentially extend mineralisation along strike and at depth.

Current Resource Base and Strategic Development Plans

Majestic North’s current JORC (2012) Mineral Resource stands at approximately 1.38 million tonnes at 1.14 g/t Au for 50,300 ounces, including an indicated component of 966,000 tonnes at 1.1 g/t and an inferred portion of 409,000 tonnes at 1.24 g/t. The higher-grade subset within this resource is a focal point for Orbminco’s development strategy, which aims to transition the project towards production via a streamlined pathway. The company plans to incorporate the infill and forthcoming junction results into an updated Mineral Resource Estimate in the second half of 2026, feeding into Stage 1 mining studies under its Mine Development Program.

Drilling Program and Analytical Rigor

The completed drilling program totaled 27 RC holes for approximately 2,220 metres, executed with industry-standard sampling and assay techniques including Photon Assay and multi-element ICP-MS analysis at certified laboratories. Quality assurance protocols involved certified reference materials and blanks, with no significant sample contamination detected. The vertical infill holes were drilled at 90 degrees to intersect the predominantly horizontal mineralisation, ensuring representative sampling and reliable assay data.

Next Steps and Market Implications

With the majority of assays pending, the market will be watching for the full picture to emerge later this year. The ability of the structural junction and basement holes to confirm or expand the high-grade domain will be pivotal. Any upgrade to the Mineral Resource could materially influence Majestic North’s development timeline and investment appeal. Meanwhile, Orbminco continues to advance its mining studies, aiming to capitalise on these promising drilling results and move closer to a final investment decision.
