Tudor Gold’s 2026 Treaty Creek Drill Program Explained

Why Bulk-Tonnage Gold Deposits Are Only Half the Story

The global mining industry has spent decades chasing scale, and for good reason. Larger resource bases attract institutional capital, support longer mine lives, and justify the infrastructure investment required to bring remote projects into production. Yet experienced resource investors understand a less-discussed reality: raw tonnage without a credible high-grade core often produces economics that struggle under real-world cost pressures. The projects that genuinely advance through the development pipeline tend to be those where a bulk-tonnage envelope contains a structurally controlled, higher-grade interior that can anchor underground extraction scenarios.

This dynamic sits at the heart of the Tudor Gold Treaty Creek drill program launched in mid-May 2026. Rather than pursuing broad resource expansion across the 17,913-hectare Treaty Creek land package in British Columbia's Golden Triangle, the 2026 campaign is specifically oriented toward unlocking high-grade structural targets that could reshape how the Goldstorm Deposit is ultimately modelled and mined. Furthermore, current gold exploration trends suggest that high-grade structural targeting is increasingly favoured over broad resource expansion as capital becomes more selective.

The Golden Triangle's Enduring Geological Significance

Northwestern British Columbia's Golden Triangle has generated some of the most consequential precious and base metals discoveries of the past three decades. The region owes its extraordinary mineralisation density to a convergence of tectonic and magmatic processes that concentrated gold, silver, and copper along a series of major structural corridors over millions of years.

The Sulphurets Thrust Fault as a Mineralisation Highway

The Sulphurets Thrust Fault corridor is not merely a regional geological feature; it is the architectural backbone controlling the distribution of mineralisation across multiple deposit systems in the area. Understanding this structure is essential to appreciating why Treaty Creek's drill targets carry strategic weight beyond their individual intercept grades.

The fault corridor acts as a conduit through which hydrothermal fluids transported metallic elements upward through the crust, depositing gold, copper, and silver in permeable or structurally prepared host rocks. Where these fluids encountered favourable chemical or physical conditions, including potassic alteration zones within dioritic intrusives, the concentrations intensified. This is the same broad geological framework that underpins Seabridge Gold's KSM property to the southwest of Treaty Creek and Newmont Corporation's Brucejack Mine to the southeast, both of which represent globally significant deposits in their own right.

The spatial positioning of Treaty Creek between these two established assets is not coincidental. It reflects the continuous nature of the Sulphurets Thrust Fault system and raises a geologically grounded question: to what extent does Treaty Creek's Goldstorm Deposit represent a single expression of a much larger, structurally connected mineralised system?

Understanding the Goldstorm Deposit's Multi-Metal Resource Base

Before evaluating what the 2026 drill program could add, it is worth anchoring the conversation in what already exists. According to the NI 43-101 Technical Report dated November 30, 2025, the Goldstorm Deposit hosts the following mineral resource estimate:

Several features of this resource deserve closer examination by investors who look beyond headline ounce counts.

First, the Inferred Resource grades significantly higher than the Indicated envelope, at 3.64 g/t gold compared to 0.85 g/t gold. This grade differential is uncommon and geologically meaningful. It suggests that the highest-grade material within the broader system has not yet been fully outlined, and that targeted drilling into structurally controlled zones could progressively upgrade both the grade and classification of material in the resource model. In addition, interpreting gold drill results in this context requires understanding how grade distribution across a large system can mask the significance of inferred higher-grade pockets.

Second, the copper and silver credits are material to any economic assessment. 3.048 billion pounds of copper at Indicated classification represents a significant byproduct revenue stream that can substantially reduce the effective cost of gold production when factored into net smelter return calculations. For comparison, many single-commodity gold development projects must justify their economics on gold price alone; Goldstorm's polymetallic character provides a natural hedge against gold price softness.

Third, the deposit remains open in all directions. This is not boilerplate exploration language. At the scale of the Goldstorm system, an open geometry means the resource model boundary is defined by the limits of drilling, not by the limits of the mineralised system itself.

The 2026 Tudor Gold Treaty Creek Drill Program: Structure and Objectives

The 2026 Tudor Gold Treaty Creek drill program is structured around two sequential phases, each targeting a distinct geological zone along the Sulphurets Thrust Fault corridor. Two diamond drills are operating simultaneously, with a minimum commitment of 10,000 metres across the season.

What distinguishes this program from a greenfield exploration campaign is the quality of data informing every drill collar. Both target zones carry documented drill histories, geophysical survey coverage, and, in the case of the CBS Zone, a freshly completed structural reinterpretation developed in collaboration with academic researchers at the University of British Columbia.

Phase 1: CBS Zone and the Goldstorm Connectivity Hypothesis

The CBS Zone occupies a lower elevation than the other priority targets at Treaty Creek, and this topographic reality carries a practical exploration advantage that is easy to overlook. Lower elevation targets can be accessed both earlier in spring and later in autumn than higher-elevation zones, effectively extending the productive drilling window at both ends of the season. Commencing Phase 1 at the CBS Zone therefore represents sound seasonal logistics as much as it reflects geological priority.

The historical intercepts driving the Phase 1 follow-up program are substantive:

• 155 metres grading 0.78 g/t gold and 2.34 g/t silver (broad mineralised envelope)
• Within that interval: 53 metres grading 1.24 g/t gold and 4.35 g/t silver (higher-grade structural core)

The relationship between these two intervals is geologically instructive. The broader 155-metre envelope establishes a large, mineralised host volume. The 53-metre higher-grade core within it suggests that a structurally controlled mechanism, likely a fault or shear zone acting as a fluid conduit, is concentrating gold above background grades within that envelope. This is precisely the architecture that underground extraction scenarios require.

The critical geological hypothesis being tested in 2026 is whether a mineralised corridor exists between the CBS Zone and the Goldstorm Deposit along the Sulphurets Thrust Fault. The two systems are considered genetically linked, meaning they likely share a common magmatic and hydrothermal origin. If drilling confirms continuous or semi-continuous mineralisation between them, the implications for resource geometry would be significant.

How UBC Research Is Changing the Drill Targeting Framework

One of the less widely discussed aspects of the 2026 program is the role of the Mineral Deposit Research Unit at the University of British Columbia in reinterpreting the structural geology of the CBS Zone. Academic geological research partnerships in commercial exploration are less common than they should be, and the integration of MDRU structural analysis into commercial drill planning represents a methodological differentiator.

The UBC MDRU reinterpretation has produced a revised model of how the CBS Zone connects to the broader Sulphurets Thrust Fault system. This reinterpretation identifies specific vectors along which Goldstorm-linked mineralisation is most likely to extend toward the CBS Zone. In practical terms, this means 2026 drill collars are positioned with greater geometric precision relative to the interpreted structural controls, improving the probability of intersecting high-grade material rather than relying on broad infill spacing.

For investors evaluating exploration-stage companies, the integration of independent academic structural research into drill targeting is a meaningful indicator of geological rigour. It reduces the reliance on in-house geological bias and subjects the exploration model to external intellectual scrutiny.

Phase 2: Perfectstorm Zone and the Dual-Model Opportunity

The Perfectstorm Zone's 8,000-metre Phase 2 allocation reflects both the scale of the geophysical anomaly identified in 2022 surveys and the geological complexity of a system that may host two distinct mineralisation styles within a single drill program.

Two Mineralisation Models in One Zone

Porphyry systems and epithermal systems are genetically related but spatially distinct expressions of the same magmatic-hydrothermal continuum. Porphyry deposits typically form at depth and are characterised by large tonnages at moderate grades, while epithermal systems form at shallower crustal levels and are associated with higher-grade but narrower mineralised corridors. The Golden Triangle is a globally recognised setting for this porphyry-to-epithermal transition style of mineralisation, and identifying both styles within the Perfectstorm Zone suggests the system has structural complexity that could yield higher-grade intercepts alongside bulk-tonnage material.

The 2023 Perfectstorm Zone drill results that are driving the Phase 2 follow-up program include:

• 102.15 metres grading 1.23 g/t gold and 3.43 g/t silver (broad mineralised interval)
• Higher-grade core within that interval: 42.5 metres grading 1.80 g/t gold and 5.76 g/t silver

Side-by-Side Comparison of Zone Drill Results

The Perfectstorm Zone's 1.80 g/t gold over 42.5 metres represents the highest-grade broad interval in this comparison set, and it is this style of result that would carry the greatest economic significance if replicated and extended in the 2026 program. Consequently, how investors read drill results from multi-zone programs like this one requires careful attention to the distinction between broad envelope grades and higher-grade internal cores.

The 2026 De-Risking Framework: Four Parallel Workstreams

The 2026 Tudor Gold Treaty Creek drill program does not operate in isolation. It is one of four concurrent workstreams that collectively advance the Treaty Creek Project along multiple de-risking pathways simultaneously.

1. Drilling program: CBS Zone and Perfectstorm Zone targeting high-grade structural corridors
2. Preliminary Economic Assessment (PEA): Underway for the Goldstorm Deposit as a potential underground mine
3. SC-1 Zone underground ramp permit application: Filed to enable physical access to and drilling of the highest-grade zone within the Goldstorm system
4. Metallurgical program: Testing processing assumptions and recoveries to inform PEA inputs

The convergence of these four workstreams in a single calendar year is strategically deliberate. Each addresses a different category of investor concern: drilling de-risks the resource geometry, the PEA de-risks the economic model, the SC-1 permit de-risks access to high-grade material, and the metallurgical program de-risks processing assumptions.

The PEA as a Structural Inflection Point

For bulk-tonnage, lower-grade systems like the Goldstorm Deposit's Indicated Resource envelope, the economic case often rests on demonstrating that a higher-grade underground core can be selectively mined at materially better margins than open-pit bulk extraction. The PEA currently underway is specifically framed around an underground mining scenario, which signals that the company's geological team believes the deposit's grade distribution supports selective mining approaches. Understanding the mining study stages that follow a PEA is important context for evaluating what this milestone represents in the broader development timeline.

Resource sensitivity analysis focused on material above 2 g/t gold is particularly relevant here. The Inferred Resource grades at 3.64 g/t gold, suggesting a higher-grade population exists within the broader system. Defining this higher-grade envelope in detail would allow the PEA to model an underground starter scenario that could generate significantly stronger project economics than the average Indicated grade alone would suggest.

Upcoming Catalysts Investors Should Track

Critical 2026 Milestones for the Treaty Creek Project:

1. Rolling assay results from CBS Zone Phase 1 drilling
2. Rolling assay results from Perfectstorm Zone Phase 2 drilling
3. SC-1 Zone underground ramp permit decision
4. Preliminary Economic Assessment completion for the Goldstorm underground scenario
5. Metallurgical program results informing processing design

The rolling release of assay results throughout the season is a characteristic of multi-rig programs that investors sometimes underestimate. Rather than a single data release event, a rolling assay schedule creates a series of smaller information releases that can progressively reshape the market's understanding of both zones' grade continuity and spatial extent.

Treaty Creek in a Global Context

At 24.9 million indicated ounces of gold, the Goldstorm Deposit sits within a very small population of undeveloped gold deposits globally. The overwhelming majority of undeveloped gold projects contain fewer than five million ounces. Projects of this scale attract a different tier of institutional attention and, eventually, a different tier of potential acquirer.

The competitive context within the Golden Triangle is also meaningful. The proximity of Seabridge Gold's KSM project and Newmont's Brucejack Mine creates both a benchmark for how large-scale Golden Triangle deposits are valued and potential infrastructure synergies that could reduce the capital intensity of any future Treaty Creek development. Shared road access, power infrastructure, and processing facilities represent optionality that remote standalone projects simply do not possess.

However, the British Columbia permitting framework for large-scale precious metals projects is complex and time-consuming. Indigenous consultation processes, environmental assessment requirements, and water management considerations all extend development timelines relative to some other jurisdictions. Investors should factor these realities into any timeline modelling. A detailed overview of the 2026 Treaty Creek drill program is available for those seeking further technical context on the program's structure and objectives.

Frequently Asked Questions: Tudor Gold Treaty Creek Drill Program

What is the total scope of the 2026 Tudor Gold Treaty Creek drill program?

The program involves two diamond drills operating across a minimum of 10,000 metres, running from mid-May through late September to early October 2026, split across the CBS Zone (2,000 metres) and the Perfectstorm Zone (8,000 metres). Tudor Gold's official Treaty Creek project page provides additional background on the broader land package and project history.

Why was the CBS Zone selected for Phase 1?

The CBS Zone sits at a lower elevation than other Treaty Creek targets, enabling earlier spring and later autumn drilling access. It also carries prior high-grade intercepts and has been the subject of a structural reinterpretation by UBC's MDRU that identifies a potential mineralised corridor connecting it to the Goldstorm Deposit.

What are the best historical drill results from the CBS and Perfectstorm zones?

• CBS Zone: 155 metres at 0.78 g/t gold and 2.34 g/t silver, including 53 metres at 1.24 g/t gold and 4.35 g/t silver
• Perfectstorm Zone: 102.15 metres at 1.23 g/t gold and 3.43 g/t silver, including 42.5 metres at 1.80 g/t gold and 5.76 g/t silver

What does porphyry versus epithermal mineralisation mean for investors?

Porphyry systems offer large tonnages at moderate grades, while epithermal systems tend to be smaller but higher-grade. Testing both styles within the Perfectstorm Zone means the program could identify either a bulk-tonnage extension of the Goldstorm system or a higher-grade structurally controlled shoot, with each carrying different economic implications.

What is the SC-1 Zone, and why does the permit application matter?

The SC-1 Zone represents the highest-grade material identified within the broader Goldstorm system. A permit application has been filed to construct an underground ramp providing physical access for drilling, which would enable detailed characterisation of this high-grade zone and inform the underground PEA's economic modelling.

When will 2026 drill results be available?

Assay results will be released on a rolling basis throughout the field season as samples are processed and compiled, rather than in a single end-of-season announcement.
