Price Sensitive Announcement $
Highlights:
Power has received all niobium and rare earth elements (REE) assay
results (pending gallium assay results) from its maiden 29 hole – 2,272m RC drilling program at the Santa Anna Project, Brazil
Drilling has intersected multiple wide zones of niobium as well as multiple zones of high-grade REE mineralisation in multiple drillholes
Highlight results include:
o 87m at 2,124ppm Nb2O5 from 24m, incl. 1m at 5,745ppm Nb2O5 from 107m and 3m at 10,117ppm Nb2O5 from 24m in MN-RC-028
o 76m to End of Hole (EOH) at 3,424ppm Nb2O5 from 24m, incl. 26m at 5,317ppm Nb2O5 from 24m, incl. 5m at 825ppm Nb2O5 from 29m and 5m at 6,802ppm Nb2O5 from 41m in MN-RC-045
o 34m at 3,019ppm Nb2O5 from 6m, incl. 5m at 5,615ppm from 20m in MN-RE-041
o 114m at 3,012ppm TREO from surface, incl. 16m at 5,300ppm TRE from 97m from MN-RC-028
o 60m at 9,202ppm TREO from surface, incl. 14m at 18,768ppm TREO from 30m in MN-RC-045
o 34m at 4,544ppm TREO from surface containing 21.3% MREO, incl. 14m at 6,936ppm TREO from surface, and incl. 3m at 9,445ppm TREO from 2m; and 16m at 5,957ppm TREO from 84m to EOH in MN-RC-025
o 35m at 8,050ppm TREO from 11m, incl. 7m at 17,163ppm TREO from 21m in MN-RC-042
o 25m at 8,809ppm TREO from surface, incl. 5m at 15,975ppm TREO from 9m and 5m at 11,483ppm TREO from 20m in MN-RC-041
Power has an option to acquire the entire 17.05km² Santa Anna project permit which hosts high-grade Nb, REE, and Ga in the upper weathered portion
Power’s drilling results highlight the Project’s expansion potential at depth, and ~89.3% of the 5.8km² Alkaline Complex surface area is untested, highlighting a potential significant scale exploration opportunity
Overview:
Power Minerals Limited has announced results from the remaining holes from its maiden drill program (29-hole, 2,272m, see Table 1) at the Santa Anna niobiumREE-gallium carbonatite project (“Santa Anna” or “the Project”) in Goiás State, in the central region of Brazil. See Figures 1 and 2.
The program was completed as part of its due diligence to potentially acquire the Project.
The Company is pleased to report that drilling has intersected multiple wide zones of niobium mineralisation as well as multiple zones of high-grade rare earth elements (REE) mineralisation.
The drilling program was designed to confirm and extend the previous significant mineralised sections (especially below current drilling), test new sections of the complex, and progress work on an Exploration Target and Mineral Resource Estimate for the project (subject to results).
Company Notes:
Power Minerals Limited Managing Director, Mena Habib says “We are excited to report the remaining niobium and REE assay results from our maiden drilling program at the Santa Anna Project. The positive results are in line with our exploration model for the Project, as it shows that mineralisation occurs at surface (weathered zone) and at depth (fresh rock) of the carbonatite. This is an important step in the determination of a significant niobium and REE carbonatite deposit. We are still awaiting the gallium results from the drilling program, which will be released upon availability. Power has the exclusive option to secure a footprint over the entire Santa Anna Alkaline Complex, which still has a very large portion of
the tenure yet to be drill-tested. This represents an exciting potential exploration opportunity.”
