Chilwa Minerals Limited announced high-grade heavy mineral sand assay results from its Mpyupyu Dune deposit. The drill data reinforces potential resource upgrades and improved project estimates with faster lab turnarounds, offering an encouraging development for investors and beginner traders alike.

Chilwa Minerals Limited has reported encouraging results from the second batch of heavy mineral sands assays at its Mpyupyu Dune deposit in southern Malawi. The company received assay data from 127 sonic drill holes totaling 947 metres, with notable high-grade intercepts such as 3.25 metres at 21.46% total heavy minerals (THM), including sub-intervals reaching over 32% THM, as well as intercepts in the 4-6 metre range with THM values between 12.99% and 24.04%. These findings support the company’s view that the most promising mineralisation is concentrated along two sub-parallel lobate strandlines within the dune area of the larger deposit. The Mpyupyu deposit currently carries an inferred mineral resource estimate of 19.9 million tonnes at 4.2% THM, with the higher grade dune portion comprising 3.5 million tonnes at 7.1% THM and the lower grade flats making up 16.4 million tonnes at 3.6% THM. Sonic drilling has been extensive across a 3-kilometre strike length with a total of 359 holes drilled for 2,716 metres, and the impressive second batch results are being integrated with previous data in anticipation of a revised mineral resource update by the end of the quarter. Improved turnaround times are being achieved through the newly appointed laboratory, Light Deep Earth in South Africa, which is expediting assay analyses. Looking ahead, the company expects an updated mineral resource estimate for the Mposa deposit in the coming weeks, while further drilling at Mpyupyu is now extending to the flats area with an additional 85 holes recently completed. In addition to its heavy mineral sands program, Chilwa Minerals is advancing its rare earth exploration by investigating 47 carbonatite targets. Soil sampling has been completed on 30 targets, with positive pathfinder results reported earlier this year, and drilling at the Mposa target is underway with results anticipated soon. From a market sentiment perspective, the strong high-grade intersection results and expedited assay processing signal a bullish outlook for Chilwa Minerals Limited, with updated resource estimates poised to potentially enhance project valuation. On the other hand, the inherent exploratory risks remain, and the reliance on inferred resources underscores the caution needed by investors as further drilling and testing are required to confirm the commercial viability of these deposits.
