Panther Metals PLC (LSE:PALM) has begun workstreams to evaluate and permit the reprocessing of historic tailings at the Winston Lake Mine site in Ontario, Canada.
"Since announcing the exciting sample assay results from the Winston Lake Mine tailings storage facility, we have been very busy setting out and commencing a series of workstreams which are designed to fast-track the assessment and build a robust economic case to reprocess and extract value from the tailings," said chief executive Darren Hazelwood.
The programme will quantify contained gold, silver, zinc, copper, cobalt, gallium and other recoverable minerals following initial sampling results announced on 31 July 2025.
The work includes historical data assessment, technical studies by appointed specialists, and early engagement with provincial authorities under a new mineral recovery regulation introduced in July 2025.
This regulation allows faster permitting for extracting residual minerals from mine waste without requiring a closure plan.
"Panther has embarked on the permitting process, which will be run in tandem with the technical studies, in order to shorten our timeline to projected cashflow," Hazelwood added.
"In layperson's terms, the planned workstreams are designed to provide the necessary numbers to quantify the economic value recoverable from the tailings and to constrain the costs involved with bringing the tailing re-processing into production and generating significant cashflow to advance the business."
