- Follow-up assays and metallurgical tests pending to support BFS
Bonanza Grades Reinforce McLaren’s Resource Potential
McLaren Minerals Limited (ASX:MML) has delivered a striking update from its McLaren Titanium Project in Western Australia, reporting heavy mineral (HM) grades soaring up to 34.6% in its ongoing resource upgrade drilling. These bonanza grades, combined with a broad swathe of consistent mineralisation, have bolstered confidence in expanding the project’s footprint and underpinning future development studies.
The company’s 13,000-metre drilling campaign is now approximately 75% complete, with 551 holes yielding 9,768 metres of data. Notably, 27% of assays in the latest batch exceed 4% HM, averaging 10.3%, while 43% surpass 2% HM. Such robust grades are significant for a mineral sands project, where higher HM percentages translate directly to more valuable concentrate.
Emerging South-Eastern Extension Highlights Growth Opportunity
A newly identified south-eastern extension area outside the current Indicated Resource footprint has revealed encouraging intersections. Drill hole MAC380 returned 22 metres from surface at 7.62% HM, including a peak 30.65% HM over a metre, while MAC379 hit 4.75% HM over 24 metres. Follow-up drilling of 12 additional holes in this zone is complete, with assay results awaited. This emerging zone could materially enhance McLaren’s resource base if continuity is confirmed.
These results support the geological model’s prediction of both upper and lower mineralised strand systems, confirming lateral continuity and basement-controlled basin geometry that traps heavy minerals. The program has also delineated broad zones of mineralisation in the northern deposit, including high-grade hits such as 8.01% HM over 24 metres in MAC155 and 7.36% HM over 18 metres in MAC169.
Drilling Progress and Geological Insights
Drilling productivity has accelerated recently, averaging 260 metres per day, with samples consistently dry and of high quality. The campaign has improved understanding of basement topography’s influence on mineral deposition, confirming the presence of heavy mineral-bearing sediments draping basement surfaces. This discovery validates the exploration concept and supports the interpretation of a preserved lower mineralised strand alongside the upper strand.
McLaren’s Managing Director Simon Finnis emphasised the value of consistent mineralisation starting from surface, which bodes well for mining economics. He highlighted the program’s role in increasing resource confidence and aiding the upcoming Resource update, Reserve estimation, and Bankable Feasibility Study (BFS) workstreams.
Next Steps Toward Resource Upgrade and Feasibility
The company expects to complete the Phase 2 drilling program by late June 2026, with outstanding assays from follow-up holes in the south-eastern extension and the Eastern Shoreline target area still pending. Subsequent metallurgical and variability test work will feed into an updated Mineral Resource Estimate and support BFS progression.
While the current results are promising, the pending data will be crucial to fully assess the scale and grade continuity of new zones. The McLaren project’s evolution remains closely watched given its strategic position in the critical minerals space, supplying titanium essential for aerospace and energy technologies.
Bottom Line?
McLaren’s bonanza grades and expanding mineralisation zones strengthen the case for resource growth, but upcoming assay results will be critical to confirm the project's next development milestones.
Questions in the middle?
- How will the pending south-eastern extension assays impact McLaren’s overall resource estimate?
- What metallurgical characteristics will the variability testing reveal about the high-grade zones?
- Could the emerging Eastern Shoreline target materially alter the project’s resource profile?
