McLaren Minerals Limited confirms its slimes management strategy using conventional mineral sands techniques. Successful test results lower development risk and simplify plant design for its titanium project, boosting confidence in a robust, low-risk approach to processing critical minerals in Western Australia.
McLaren Minerals Limited has announced promising progress for its titanium project in Western Australia following a comprehensive metallurgical test program conducted by IHC Mining and SciDev. The tests verified that the company’s approach to managing slimes—the fine, leftover material from mining—can be effectively implemented using established techniques from the mineral sands industry. Key findings include the successful thickening of slimes to approximately 26% solids and the demonstration that water conditioning with low-grade gypsum (at 3% by weight) provides superior settling and dewatering results. The validation of flocculant dosage rates (approximately 150–200 g/t per slime unit) and settling flux parameters (0.1 to 0.2 t/m²/hr) reinforces the suitability of conventional processing equipment.
The detailed study also confirmed that the co-disposal of slimes with coarse tailings is feasible, even when dealing with higher slime proportions up to 38%. This is supported by slump tests showing stable mixtures and acceptable pumping performance. The test work not only validates several important design assumptions—including thickener sizing and operation, updated water and mass balances, and tailings infrastructure improvements—but also lays a solid foundation for advancing the plant engineering phase. In light of these results, McLaren Minerals Limited is set to progress with finalizing its process plant design and further confirm test outcomes under actual site water conditions, while additional studies on tailings consolidation and sample processing continue.
The news suggests a bullish outlook, as the positive test results de-risk a major element of the project. Investors may interpret the reduction in technical and operational uncertainty as a sign that the project could progress more efficiently, enhancing its potential to supply a critical mineral used in aerospace, defence, and energy sectors. The use of conventional processing techniques could also streamline capital and operating expenditures, an encouraging indicator for future project returns.
On the bearish side, some caution remains as the upcoming steps include further tests under site-specific water conditions and additional engineering studies. Any unexpected challenges during these phases, as well as potential delays in finalizing the process design, could temper near-term enthusiasm. Overall, while the technical validation is a strong positive, the full impact on project timelines and costs will become clearer as the company moves forward with its engineering and operational plans.
