Using a 1% heavy minerals cutoff, Base Resources Ltd. estimated JORC-compliant total mineral resources of 5.62 million tonnes of heavy minerals contained within 134.6 million tonnes of ore at an average heavy mineral grade of 4.2% and 26% slimes at its Kwale mine in Kenya.
The resource represents a 2% year-on-year increase in contained heavy minerals. Meanwhile, the ilmenite, rutile and zircon grades were 57%, 13% and 6%, respectively.
Mineral resources included 102.5 million tonnes of reserves containing 4.68 million tonnes of heavy minerals, according to an Oct. 11 release.
This updated estimate was a result of revised geological interpretations following further evaluation of 1,718 drill samples and observation of test pits in the South Dune deposit, as well as knowledge acquired from mining.
In June, the ASX-listed company secured exploration tenure over an expanded land area of 136 square kilometers at Kwale.
