Chilwa Minerals (ASX:CHW) confirmed "substantial" niobium mineralization over an entire drillhole from its Lake Chilwa license in Malawi, with an average of 0.17% niobium pentoxide over 385 meters from surface, according to a Tuesday filing with the Australian bourse.
Portable X-ray fluorescence results showed that higher-grade niobium zones, notably 0.24% niobium pentoxide over 60 meters, are situated within specific rock types that are traced between drillholes, the filing said.
Further results will be available in the near term, alongside additional results from the remaining nine drill holes at the Nakombe target, per the filing.
