Yalgoo

The Yalgoo project is a key focus for Premier1, located within the Yalgoo-Singleton Greenstone Belt, a highly prospective region hosting major copper-gold mines including Golden Grove and Deflector. The project covers 220 km² and includes over 25 km of untested mineralised shear zones. Historical exploration, primarily limited to shallow drilling, identified high-grade gold mineralisation, including standout intercepts of 5m at 5.1g/t Au and 10m at 6.4g/t Au. This mineralisation remains largely untested at depth and along strike, presenting significant upside potential. Notably, the historical work, which dates back over 30 years, focused on oxide zones near surface and was almost solely focused on known gold mineralisation around old (circa 1900) mine workings. Deeper high-grade zones and mineralising structures along strike and down dip/plunge are largely untested by modern drilling techniques.

Premier1 may earn 70% in all mineral rights (excluding rare earths) by expending up to $4.5m in two stages ($1.5m to earn a 51% over two years and $3m for an additional 19%).
