Aldoro Resources (ASX:ARN) has reported assay results from two additional phase two holes at its Kameelburg rare earth elements-strontium-niobium project in Namibia.
Hole DD008G returned 318.3m @ 1.51% total rare earth oxides (TREO), 4.90% strontium carbonate, 0.21% niobium pentoxide, and 174 parts per million (ppm) molybdenum from surface using a 1% TREO cut-off.
The company says this represents ‘one of the thickest and most consistently graded composite intersections’ in the phase two program.
Two perpendicular holes from the DD008 pad now provide three-dimensional constraints on what Aldoro describes as a key resource block for the upcoming phase two mineral resource estimate (MRE).
At DD005D, drilling confirmed ‘high-grade’ rare earth elements (REE) from surface and deep niobium at the southern margin.
The hole returned 136.3m @ 1.97% TREO and 5.21% strontium carbonate from surface, representing a near-surface, ‘high-grade’ REE zone consistent with the rich sovite core intersected at every central pad hole to date.
A 52m niobium interval @ 0.24% niobium pentoxide in the upper layer confirms niobium persistence at the southern carbonatite margin.
The company also reports a 210.8m niobium zone in the lower layer grading 0.40% niobium pentoxide, including 47m @ 0.51% niobium pentoxide from 363m to 410m and 14m @ 0.55% niobium pentoxide from 509m to 523m.
As previously reported by Mining.com.au, Aldoro’s metallurgical testwork achieved 72% total REE extraction and greater than 99% strontium recovery, with ore able to be directly leached without prior beneficiation.
Phase two drilling of 15 holes totalling 7,190m is complete, with assay results for 12 of the 15 holes available and three pending. Each new set of assays continues to confirm Kameelburg as a large, continuous, multi-commodity mineralised system.
Aldoro expects to release the updated phase two MRE upon receipt of the remaining assays, which the company says will reflect the full scale of what Kameelburg has shown across the program.
