Just to muddy the waters a bit as to exactly what stake WR1 does hold is the most recent information I could find from announcements.

Quarterly Activities Report
Published: 30/04/25, 08:53am (AEST)

Winsome holds a substantial stake in TSX-V and FSE-listed Power Metals Corp (“PWM”) as well as 100% of the offtake rights to lithium, tantalum and cesium products from the Case Lake Project in northeastern Ontario, Canada.

During the quarter, Winsome sold some of its shareholding in PWM. The decision to divest a portion of our PWM shareholding was driven by funding initiatives and the opportunity to monetise a portion of the investment.
