McLaren Minerals (ASX:MML) has disclosed the final assay results from its 2026 Mineral Resource Upgrade and Expansion drilling program at the wholly owned McLaren Titanium Project in Western Australia, with the 137-hole final batch comprising 2,210 metres of sampled interval returning a length-weighted average of 4.27% heavy mineral (HM) grade with no HM cut-off applied.
Key Points
- The final 137-hole batch (MAC645–MAC760, MAC766–MAC786) comprises 2,210 metres of sampled interval with a length-weighted average of 4.27% HM and no cut-off applied.
- 34 holes in the final batch averaged at least 5% HM, including nine averaging at least 6% HM, with the highest individual one-metre assay reaching 14.15% HM in MAC670.
- Mineralisation extends south-west, outside the current Inferred Resource, with MAC773 returning 21 metres from surface at 6.35% HM and the resource remaining open to the south.
- All 20 holes in the southern variography grid averaged at least 5.40% HM over 21 to 24 metres from surface, with MAC719 recording 24 metres at 6.13% HM.
- Work on the Mineral Resource Estimate update is underway, incorporating the completed 2026 assay dataset into geological modelling.
Final Batch Assay Results from 2026 Drilling Program
The final batch covers drillholes MAC645 to MAC760 and MAC766 to MAC786, delivering 2,210 reported one-metre assays. Within the dataset, one metre returned no result (MAC671). Of the 137 holes, 69 averaged at least 4% HM, 34 averaged at least 5% HM, and nine averaged at least 6% HM across their reported assays. In terms of sampled thickness, 92 holes (65%) recorded intervals of at least 15 metres, 66 holes (47%) at least 18 metres, and 53 holes (37%) at least 21 metres. These figures represent sampled thicknesses, not cut-off-defined mineralised intersections, according to the filing.
Variography Grid Results and South-Western Extension
The final assay release includes results from two dedicated variography drilling grids totalling 40 drillholes. The southern grid consists of 20 drillholes (MAC710–MAC729) and the northern grid a further 20 drillholes (MAC741–MAC760). All 20 holes in the southern variography grid averaged at least 5.40% HM over 21 to 24 metres from surface. Separately, drillholes MAC773, MAC774, and MAC771 demonstrated mineralisation extending south-west outside the current Inferred Resource, with the resource stated to remain open to the south. Drillholes MAC771 and MAC767, located at the southernmost extent of the 2026 exploration grid, returned 17 metres at 4.76% HM and 16 metres at 4.71% HM respectively.
High-Grade Intersections and Mineral Resource Estimate Update
Standout intersections from the final batch include MAC773 at 21 metres from surface at 6.35% HM, MAC650 at 9 metres from surface at 9.32% HM, and MAC649 at 6 metres from surface at 8.49% HM. Across the full 2026 program, 91 holes returned one-metre assays of at least 6% HM and 17 holes recorded one-metre assays of at least 10% HM, led by 14.15% HM in MAC670. The company disclosed that work on the Mineral Resource Estimate update is underway, with the completed dataset to be integrated into geological modelling. The filing states no revised estimate is contained within this release. Subsequent workstreams include mine planning, metallurgical programs, and Bankable Feasibility Study activities.
