-- Aldoro Resources (ASX:ARN) said its updated inferred mineral resource estimate (MRE) for its 85%-owned Kameelburg project in Namibia stands at 597.1 million tonnes at 2.5% total rare earth oxide (TREO) equivalent, a 15% tonnage increase on the September 2025 Phase I MRE at unchanged grade, according to a Monday Australian bourse filing.
The company said the high-grade subset has expanded to 312.7 million tonnes at 2.9% TREO equivalent at a 1% TREO cut-off, with high-grade tonnes more than doubling since the September 2025 update, supporting selective bulk open-pit mining in the early years of development.
A maiden strontium mineral resource has been declared as a co-located by-product credit of 596 million tonnes at 2.2% strontium, inclusive of and not additional to the TREO resource, the filing added.
The MRE is based on 29 diamond drill holes for 12,044 meters, with the final Kameelburg Phase II MRE expected in June, with the resource remaining open along strike, down-dip, and at depth in all directions, the filing added.
The company's shares rose 5% in recent Monday trade.
