▪ In parallel, Power is set to commence a 10,000m RC drilling program at Santa Anna to extend the project’s mineralised footprint east and south-east of initial drilling, targeting niobium and REE in untested areas of the Santa Anna Alkaline Complex
▪ Initial 2,000m of RC drilling is expected to start in November 2025, with completion expected in Q1 2026
▪ Power’s drilling aims to deliver the first Mineral Resource Estimate for the Santa Anna alkaline carbonatite complex
▪ Consistent grades received from drilling to date indicate a potential high grade and advanced critical mineral exploration opportunity
▪ The shallow auger drilling contains many mineralised intercepts from surface, indicating no significant overburden at these sites.
▪ Power holds a binding option over the entire recently discovered (2023) alkaline carbonatite complex within the Goiás State, central Brazil

▪ 14m at 2,791ppm Nb2O5 from surface to EOH, including 2m at 5,936ppm Nb2O5 from 9m in drillhole MN-TM-010
Highlight rare earth element (REE) results include:
▪ 17m at 6,895ppm total rare earth oxide (TREO) from surface to EOH, including 9m at 10,097ppm from surface and 5m at 13,824ppm (or 1.38%) TREO from 2m in drillhole MN-TM008;

▪ 13.75m at 6,534ppm TREO from surface to EOH, including 3m at 9,181ppm (or 0.92%) TREO
from 2m in MN-TM-007;
▪ 3m at 6,346ppm TREO from 1m in drillhole MN-TM-006;
▪ 11m at 3,800ppm TREO from surface to EOH, including 2m at 7,437ppm TREO from 2m in drillhole MN-TM-005; and
▪ 4m at 8,849ppm TREO from 2m, including 1m at 10,993ppm (or 1.01%) TREO from 5m in drillhole MN-TM-010.
Power’s auger drilling program is following up its recently completed maiden 29-hole, 2,272m reverse circulation (RC) drilling program at the Santa Anna Project1 and is designed to extend the Project’s mineralised footprint to the east and south-east of initial drilling, targeting shallow niobium and REE in unexplored areas of the Santa Anna Alkaline Complex.
Results from Power’s auger and RC drilling to date continue to build confidence towards achieving its near-term Project goal of confirming a significant Mineral Resource Estimate (MRE).
The auger drilling is continuing, and Power’s extensive 10,000m RC drilling is expected to commence in the current month, with an initial 2,000m of reverse circulation (RC) drilling. Completion of the initial stage is expected in Q1 2026.
Company Notes:
“Latest results from our ongoing auger drilling at Santa Anna continue to validate our exploration model and provide confidence about the potential of this project, as we compile drill data to define a maiden Mineral Resource Estimate for the project, which we hope will be substantial.
Having already announced our next phase of drilling for Santa Anna, a major reverse circulation campaign of up to 10,000m, we are looking to rapidly advance our understanding of this project’s geology. The initial 2,000m of RC drilling is due to commence this month, with assay results and further drilling planned to systematically follow over the coming months.”
