Cobra Resources (LSE:COBR) has completed resource-definition drilling across its Wudinna rare earth prospects, drilling 74 holes for roughly 3,200m to support an initial Mineral Resource Estimate for aquifer-hosted ionic REE amenable to in situ recovery, and early assays from Boland show multiple >1,600ppm TREO intersections.
Cobra Resources, a South Australian critical minerals developer, reported 32 holes at Boland with preliminary assays from 14 holes including CBSC0016 which returned 5.2m at 1,674ppm TREO (38.3ppm Dy2O3+Tb4O7 and 363ppm Nd2O3+Pr6O11) and CBSC0018 which returned 7.2m at 1,751ppm TREO, the company said.
Samples from both prospects have been submitted for REE, total organic carbon and total sulphide analysis and particle-sizing and additional metallurgical testing will be used to model permeability, ISR recoverability and natural acid-generation to support economics.
"This drilling is the catalyst to demonstrate project economics and the ability to generate sulphuric acid organically is a project elevator and should not be underestimated," said Rupert Verco, Managing Director.
Further assay results are expected over the next six to eight weeks and independent technical consultants have been engaged to complete the MRE and an order-of-magnitude scoping study.
