HIGH-GRADE GOLD STRIKES IN PREMIER1’S MAIDEN YALGOO DRILL PROGRAM

Crescent South delivers standout intercept of 3m at 31.5 g/t Au including 1m at 91.9 g/t

Premier1 Lithium Limited (ASX:PLC) has reported strong assay results from its inaugural drilling campaign at the Yalgoo Project in Western Australia, confirming high-grade gold mineralisation across multiple targets including Carlisle, Crescent South, and a newly identified zone west of Olive Queen.

Highlight intercepts from the program include:

Carlisle:
- 10m at 3.1 g/t Au from 19m, including 7m at 4.3 g/t Au (25GGRC019)
- Eastern extension of a previous 17m at 1.4 g/t Au intercept (RC040), suggesting potential for a new north-dipping mineralised structure
Crescent South:
- 3m at 31.5 g/t Au from 97m, including 1m at 91.9 g/t Au (25GGRC001)
- 1m at 27.2 g/t Au from 83m (25GGRC016)
- Mineralisation hosted on a north-south structure with an untested southern extension
Olive Queen (new discovery):
- First drilling intersected 1m at 1.5 g/t Au from 96m, within 5m at 0.4 g/t Au (25GGRC023)
- Pathfinder element anomalies (Bi, Te, Mo) support potential for a deep-seated mineralising system linked to a transform fault

The program targeted geochemical anomalies and previously untested zones, resulting in the extension of known mineralised trends and the identification of a new system at Olive Queen, broadening the project’s exploration potential.

Managing Director Jason Froud commented:

We are very pleased with the results from our maiden drilling program at Wadgingarra and the first in over 40 years. The drilling has delivered some of the highest-grade intercepts recorded on the project to date. The confirmation of high-grade gold at Carlisle, including 7m at 4.3g/t Au, highlights the untapped potential of historically overlooked areas, while the intercept of 3m at 31.5 g/t Au at Crescent South demonstrates the potential for high-grade gold along trend from known mineralisation.

Importantly, the identification of a previously unrecognised target area west of Olive Queen, along with associated pathfinder element anomalism, opens a new exploration front with strong structural and geochemical support for further discovery.

These results underscore the effectiveness of our integrated exploration approach and support our belief that Wadgingarra has significant potential to host multiple gold-bearing structures. We look forward to building on this momentum with follow-up drilling and continued refinement of our geological models as we work towards defining a robust pipeline of targets for future resource development.
