Tudor Gold Confirms Dual Mineralised Systems 1km From Goldstorm

Tudor Gold drilled four holes into its Perfectstorm target this season and confirmed something the company had hoped for but never proven: two separate mineralised systems sitting one kilometre from the largest undeveloped gold deposit in British Columbia’s Golden Triangle.

The results, released on 6 August 2026, landed at a loaded moment. Tudor Gold’s flagship Goldstorm deposit, a 24.9 million ounce gold resource, is weeks away from a Preliminary Economic Assessment (PEA) targeted for Q3 2026. That study will tell investors whether a selective underground mine at Goldstorm can generate returns. Perfectstorm is not part of it.

That distinction matters. Here is why the new drill results change the geological story at Treaty Creek without yet changing the financial one, and what specific milestones would need to be met before these intercepts carry real weight in a valuation model.

Dissecting the dual mineralised system at Perfectstorm

The initial 2026 drill campaign at Perfectstorm achieved more than a simple extension of known mineralisation. Results from the four-hole programme established that two chemically distinct systems occupy the same structural corridor, stacked at different depths within the northeast-southwest trending Sulphurets fault zone, a regional structure that controls multiple significant deposits across the Golden Triangle.

The Golden Triangle district geology has produced multiple world-class deposits along the same regional fault corridors, a structural setting that explains why Perfectstorm’s position within the Sulphurets fault zone is treated as significant rather than coincidental.

The deeper of the two, dubbed the Perfectstorm Porphyry (PSP), is the surprise. It returned copper, molybdenum, gold, and silver from potassic-altered intrusive rock, a metal mix that Goldstorm does not carry in meaningful concentrations. The shallower system, the Perfectstorm Epithermal (PSE), confirmed strike continuity of gold-silver vein-hosted mineralisation over more than 360 metres.

The shallower Perfectstorm Epithermal zone fits a geological template well established in the Golden Triangle, where epithermal gold mineralisation typically forms at shallow crustal depths from low-temperature hydrothermal fluids, producing the vein-hosted gold-silver assemblages that the PSE intercepts confirm over more than 360 metres of strike.

The specific intercepts from the August release tell the story clearly. All widths are downhole; true widths have not been determined.

PSP (Porphyry) Zone:

• 82.90m at 0.24 g/t Au, 2.11 g/t Ag, 0.21% Cu, 50.76 ppm Mo (including 10.50m at 4.59 g/t Au and 0.67 g/t Ag)
• 67.35m at 0.34 g/t Au, 1.89 g/t Ag, 0.27% Cu, 53.72 ppm Mo

PSE (Epithermal) Zone:

• 74.15m at 0.78 g/t Au and 2.90 g/t Ag (including 9.10m at 2.16 g/t Au and 3.18 g/t Ag)

The copper and molybdenum in the porphyry system is what separates this from being “more of the same.” Gold-silver deposits are what Treaty Creek already has in abundance. A copper-moly porphyry sitting beneath an epithermal gold blanket is a vertically zoned hydrothermal system, the kind of architecture that characterises large-scale, multi-metal districts globally. If tonnage and grades hold up with further drilling, this metal mix could add a fundamentally different revenue stream to the Treaty Creek project rather than simply adding more gold ounces to an already large pile.

The economic leverage of a one kilometre step out

The Perfectstorm zone occupies a position roughly 1 kilometre to the southwest of Goldstorm, sharing the same underlying structural trend. That proximity is the single most important variable in determining whether these early drill hits ever translate into cash flow.

A satellite deposit located within trucking distance of a central processing plant does not need its own mill, its own power supply, or its own tailings facility. It needs ore that is metallurgically compatible with the planned flowsheet and grades that sit above the marginal cost of mining and hauling. Every tonne of satellite feed that meets those thresholds extends mill amortisation across more ounces and smooths grade profiles across the mine life, both of which lift project-level net present value without proportional capital increases.

The regional infrastructure picture around Treaty Creek supports the satellite logic. Highway 37 and the Northwest Transmission Line are located around 40 kilometres to the east of the property, offering prospective road access and high-voltage power. Concentrate could move through the deep-water facilities at Stewart for export. The operating Brucejack Gold Mine lies approximately 20 kilometres to the south, demonstrating that production-scale projects can be built and run in this part of the Golden Triangle.

The multi-metal character of the Perfectstorm porphyry, carrying copper and molybdenum alongside gold, positions Treaty Creek within the broader British Columbia critical minerals sector narrative, where provincial policy has increasingly prioritised projects capable of supplying metals essential to electrification and defence supply chains.

The table makes the gap visible. Goldstorm has 190,000+ metres of drilling and a formal resource containing 24.9 Moz gold in the Indicated category alone (at 0.85 g/t Au across 912.3 Mt). Perfectstorm has a fraction of that drilling and contributes nothing to the current mineral resource estimate. The proximity advantage is real, but it only converts into economic value once the geological data catches up.

Bridging the gap between drill holes and modelled value

Four holes and a geological concept do not constitute a mineable resource. Perfectstorm currently sits on the exploration side of a boundary that takes years and tens of thousands of additional drill metres to cross.

The Goldstorm resource estimate, prepared by qualified person Garth Kirkham, P.Geo. of Kirkham Geosystems, was built on 359 holes totalling 191,466 metres with an effective date of 30 November 2025. Perfectstorm has roughly 7,752 metres of historical drilling plus the initial 2026 holes. Tudor Gold has allocated approximately 8,000 metres of Phase 2 drilling to Perfectstorm as part of a minimum 10,000 metre overall 2026 programme. That is a meaningful commitment, but it is a starting point in what will likely be a multi-season campaign.

Both systems remain open in all directions. That is encouraging for scale potential but also means the geometry, continuity, and grade distribution of each zone are not yet defined in three dimensions, a prerequisite for any compliant resource estimate.

The path to a maiden resource estimate at Perfectstorm requires not just additional drill metres but a structured workflow: geological modelling, grade interpolation, classification by confidence category, and sign-off by an independent qualified person, a process that typically requires multiple seasons of data before compliant results can be published.

The path to a maiden resource

Drilling alone is not sufficient. Before Perfectstorm can enter a future mine plan, the metallurgy of both the porphyry and epithermal material must be tested against the planned Goldstorm processing flowsheet. If Perfectstorm ore requires radically different grinding, a separate processing route, or exhibits poor recoveries for copper and molybdenum, its practical importance diminishes regardless of the resource size. Geotechnical and hydrogeological studies would also need to establish ground conditions for either open-pit or underground extraction.

The real inflection point comes when an updated PEA or pre-feasibility study incorporates Perfectstorm into the cash flow model and demonstrates higher NPV, longer mine life, or improved payback versus a Goldstorm-only scenario. Until that work is complete, Perfectstorm is geological optionality, not modelled value.

Watching the Phase 2 drill bit and the Q3 milestone

Two catalysts sit directly ahead. The remainder of the ~8,000 metre Phase 2 drill programme at Perfectstorm will determine whether the porphyry and epithermal systems expand in the lateral and vertical directions needed to justify a future maiden resource estimate. Consistent grade continuity across additional holes would give the market reason to assign increasing speculative value to the zone.

The nearer-term event is the Q3 2026 underground-focused PEA for Goldstorm. That study remains the anchor for Tudor Gold’s valuation. It will provide the first formal economic framework for Treaty Creek, including the central processing plant concept that any future satellite feed from Perfectstorm would depend on. Until the PEA demonstrates viable economics for the core deposit, the satellite story remains exactly that. Watch both drill bits, but price the PEA first.
