DRILLING
The company has held a pre-submission meeting with the regulatory authority and will progress through the four-stage process alongside continuing other work at the site.
Grid drill sampling is underway to support metallurgical testwork and reprocessing studies as well as defining a compliant inaugural mineral resource estimate for the tailings deposit.
Panther aims to begin a drill sampling at the tailings deposit campaign this month.
In operation from 1988 to 1998, Winston Lake mine produced around 3.3 million tonnes of ore.
Panther states that a “significant” quantity of valuable material remains in the tailings including high-grade gold, gallium, silver, zinc, copper, cobalt and other minerals.
The company additionally reported that 1,067,764 warrants expired unexercised during August 2025.
These comprised 834,909 warrants relating to the 2022 placing, and 232,855 warrants issued in respect of the 2023 convertible loan note.
