Aldoro Resources (ASX:ARN) said a diamond drill hole from the Kameelburg project in Namibia returned the longest single mineralized intercept reported to-date at the project, with continuous niobium-rare earth elements-strontium mineralization across the entire 503.98 meters of drilled depth, according to a Friday Australian bourse filing.

It reported an intercept of 503.98 meters at 1.3% grade of total rare earth oxides, 4.01% grade of strontium carbonate, 0.17% grade of niobium oxide, and 190 parts-per-million grade of molybdenum from the surface, confirming the carbonatite is mineralized across its entire eastern flank.

The drill hole is expected to contribute substantial tonnage to the updated mineral resource estimate scheduled for release in June.
