The company has secured what CEO Darren Hazelwood calls a game-changing opportunity: the Winston Tailings Project in Ontario. Unlike many juniors that face long roads to revenue, Panther’s thesis is that re-processing historic tailings with existing infrastructure could provide a quicker path to cash flow — and at a scale that matters.
With a current market cap of around £4.9 million, the upside case here has caught investor attention.
Winston Tailings: The Opportunity
Winston was historically mined between 1988 and 1998, with ~3.3 million tonnes of ore processed. Those operations left behind a large tailings storage facility (TSF) containing significant residual metals.
Recent assay results confirmed the presence of:
-
Up to 0.814 g/t gold
-
21.9 g/t silver
-
2.20% zinc
-
0.20% copper
-
496 ppm cobalt
-
122 ppm gallium
Management estimates that the tailings could contain hundreds of millions of US dollars’ worth of metal in situ — before metallurgical recovery factors are applied.
Infrastructure Advantage
Unlike most junior projects, Winston comes with critical infrastructure already in place:
-
A 115 kV power line on site
-
All-weather roads and access
-
Freshwater facilities
-
An active water treatment plant
-
Site buildings and offices
This means the CAPEX hurdle is lower. Tailings could be dredged, moved to a compact treatment facility, and then returned to the same pond — reducing cost, complexity, and environmental footprint.
What the Numbers Say (in £)
The 2021 feasibility study for the Pick deposit + Winston mine site (separate from tailings) outlined:
-
Pre-tax NPV of ~C$175.8 million (≈ £100 million)
-
Estimated CAPEX of C$145 million (≈ £83 million)
-
IRR of ~26%, with EBITDA of ~C$67 million per year (≈ £38 million)
The tailings opportunity would sit on top of this, potentially providing early cash flow to support a mine build or further exploration without heavy equity dilution.
Near-Term Steps
Panther has already begun the permit application process for the Recovery of Minerals Permit in Ontario. The roadmap includes:
-
Drilling and metallurgical testwork on the tailings pond to define recoveries.
-
Flowsheet design for a fit-for-purpose treatment plant.
-
Funding strategy, with Hazelwood clear that debt, not equity, would be preferred if the economics stack up.
-
Timeline acceleration: rather than waiting for winter freeze, drilling will begin sooner via a floating boom.
Wider Portfolio Implications
Winston isn’t Panther’s only play. The company is also advancing:
-
Pick Deposit (Ontario) – forms part of the broader Winston mine study.
-
Wishbone VMS Camp (Canada) – targeting a 15-hole drill programme.
-
Awkward Project (Canada) – management recently said partnerships are off the table, preferring to keep full upside.
With Winston tailings potentially generating cash, Panther could push these projects forward on its own terms, without resorting to “low-ball” market deals.
Risks Retail Investors Should Know
-
Metallurgy – assays don’t equal recoveries; lab tests will determine how much metal can actually be extracted.
-
Permitting – approvals are needed, even with infrastructure in place.
-
CAPEX creep – even small plants can run over budget.
-
Commodity prices – project economics depend on supportive gold, silver, and base-metal markets.
Can Winston Transform Panther?
At a £4.9m market cap, Panther trades at a deep discount to the numbers already outlined in feasibility studies — never mind the potential upside from tailings.
Catalysts to watch:
-
Metallurgical results from Winston tailings.
-
Permit updates from Ontario regulators.
-
Treatment plant design and costs.
-
Funding route (debt vs. equity).
Bottom Line
Panther Metals believes Winston tailings could provide low-capex, near-term cash flow that funds its broader ambitions. If recoveries confirm management’s bullishness, Panther could move from a small explorer to a self-funded developer — without punishing dilution.
It’s early days, and metallurgy will decide the real outcome. But with infrastructure in place and grades looking promising, Winston could be the project that finally unlocks Panther’s potential.

Junior mining companies are high risk. Project economics depend on metallurgical recoveries, permitting, funding, costs, and commodity prices — all of which can change.
