AuKing Mining (ASX:AKN) has disclosed high-grade rare earth mineralisation at East Tundulu, a previously untested carbonatite located more than one kilometre east of the Nathace Hill target zone at the company's Tundulu Rare Earth Project in southern Malawi, with maiden RC drill hole 26TH015 returning 67 metres at 1.68% total rare earth oxides (TREO) from surface.

Key Points

Drill hole 26TH015 at East Tundulu returned 67m @ 1.68% TREO from surface, including 12m @ 2.56% TREO from 5m and a peak of 2m @ 3.53% TREO from 25m
East Tundulu is situated over 1 km east of Nathace Hill and had never previously been drill tested prior to this initial RC drilling program
Additional high-grade results were reported from Nathace Hill drill holes 26NH023, 26NH032 and 26NH033, with 26NH032 returning 2m @ 7.50% TREO from 45m
The company has commenced reporting magnet rare earth oxides (MREO), with a high of 29.07% MREO/TREO recorded in hole 26NH032 at the 15–16m interval
Drill holes 26NH023 and 26NH032 were extended beyond their planned 300m depths to 400m and 510m respectively following geological logging of multiple carbonatite intersections

East Tundulu Maiden Drilling Results

Drill hole 26TH015 was designed to test the fringes of an arcuate magnetic low identified from AuKing's aeromagnetic survey conducted in May. The hole was positioned more than one kilometre east of the primary Nathace Hill target zone and drilled back towards Tundulu Hill. Key intersections from 26TH015 include 12m @ 2.56% TREO from 5m, 3m @ 3.21% TREO from 12m, 1m @ 3.51% TREO from 16m, 11m @ 2.28% TREO from 25m, and 2m @ 2.47% TREO from 65m. According to the filing, the near-surface nature of the mineralisation offers scope for shallow follow-up drilling to assess its grade and extent.

Nathace Hill Assay Results Including Deep Drill Holes

The latest batch of assay results from the north-eastern area of Nathace Hill includes results from drill holes 26NH023, 26NH032 and 26NH033. Hole 26NH023 returned 34m @ 1.68% TREO from surface, including 6m @ 5.33% TREO from 15m and 2m @ 4.56% TREO from 2m. Hole 26NH032 recorded 10m @ 2.46% TREO from 39m, including 2m @ 7.50% TREO from 45m. Hole 26NH033 reported 32m @ 1.43% TREO from 52m and a separate interval of 54m @ 1.27% TREO from 93m. The RC sampling for hole 26NH032 ended in a 2.31% TREO interval, according to the filing.

MREO Reporting and Ongoing Assay Pipeline

AuKing disclosed it has commenced reporting magnet rare earth oxides (MREO) alongside TREO figures in its assay results. The highest MREO proportion reported to date is 29.07% MREO/TREO, recorded in hole 26NH032 at the 15–16m interval. The filing states this appears consistent with observed apatite-rich phases of the carbonatite mineralisation. The company stated a strong pipeline of assay results is expected to continue over the coming weeks as it works to define the scale and extent of the mineralised system at Tundulu, with assays from the two extended deep drill holes, 26NH023 and 26NH032, still to be reported.
