Alvo Minerals Limited (ASX: ALV) has mobilized a diamond drill rig to test the saprolite clay depth profile at the Bluebush REE Project.
Bluebush is located on the northern half of the Serra Verde granite, host of the world-class Serra Verde Ionic Clay REE deposit, the only ionic clay deposit currently being commissioned outside of China.
Rob Smakman, Alvo’s managing director, commented, “Our confidence in Bluebush is growing following the exceptional drill results we released last week from Bluebush. We intend to test the saprolite clay depth profile immediately at areas with the higher grade MREOs. Auger holes have a limited depth capability and with holes such as BLG008 ending in 3,779ppm TREO (26% MREO), we are confident in extending the modelled depth of high-grade mineralization.”
The initial diamond drill programme of up to 1,000m will focus on testing the saprolite clay depth profile across the Boa Vista prospect. Auger drilling to date at Boa Vista did not always reach bedrock, with many of the holes ending in the highest grade MREO values recorded, including:
- BLG08: 6m @2,537ppm TREO (21% MREO) to EOH from 0m
- Inc. 3m @3,415 TREO (24% MREO) to
- EOH from 3m EOH (1m): 3,779ppm TREO (26% MREO)
- BLG05: 6m @1,243ppm TREO (23% MREO) to EOH from 8m
- EOH (1m): 1,729ppm TREO (25% MREO)
- BLG05: 6m @1,243ppm TREO (23% MREO) to EOH from 8m
- EOH (1m): 1,729ppm TREO (25% MREO)
The company will now prioritize Alvo’s wider Brazilian exploration schedule, cognizant of the six month due diligence period, expiring in December 2023. Alvo intends to build a better understanding around the potential scale, grade, and recoverability of the MREO mineralization at Bluebush.
Additionally, a soil sampling and mapping programme has been instigated in areas towards the middle of the Serra Dourada granite. These areas have more difficult access and are therefore more suitable on foot.
