MX Exploration: Three Tiers of Abitibi Gold, Three Risk Profiles

MX Exploration controls 570 km² in the Abitibi Greenstone Belt, one of the world’s most productive gold jurisdictions. Six drill rigs turn year-round across two provinces. And on 10 September 2026, the company announced a brand-new gold zone sitting roughly 165 metres directly beneath the development ramp it is already building.

That last detail is the one worth pausing on. Most exploration discoveries arrive somewhere on a 570-square-kilometre map that then has to be reached, permitted, and developed from scratch. This one showed up underneath infrastructure the company is constructing right now.

The exploration programme runs in parallel with a mine development pathway, not instead of it. The Champagne Zone resource and the Phase 1 feasibility study are the known quantity. The 570 km² drilling machine is the upside case, and it carries its own capital envelope: CAD 49 million committed across 2026 and 2027, with a dedicated team and separate reporting lines.

What follows breaks down each component of the programme, what the results actually mean geologically, and the specific catalysts investors tracking this story should be watching over the next 12-18 months.

A 570 km² exploration machine running alongside a mine in development

The scale is the first thing to understand. Here are the core parameters of the programme as it stands in late 2026:

• 570 km² total land package spanning Quebec and Ontario
• Six drill rigs operating year-round: four in Quebec, two in Ontario
• More than 70 km of total strike length across the property
• CAD 25 million exploration budget for 2026 and CAD 24 million for 2027
• 70,000-80,000 metres of drilling planned for 2027 alone

That land position is a substantial expansion from where the company started. When Perron was the sole focus, the footprint was roughly 45 km² in Quebec. The property now spans two jurisdictions and two distinct geological plays, which is a very different proposition to fund and manage.

Dual teams, separate mandates

The structural decision underneath the numbers is the one that matters most for how investors should read the risk. MX Exploration separates its mine development team from its exploration team, with distinct budgets, distinct mandates, and distinct reporting lines.

The logic is straightforward. Development teams are measured on throughput, cost control, and permitting; exploration teams are measured on discovery and resource growth. Keeping them apart reduces the risk that near-term production pressure quietly starves frontier targeting of capital and field logistics.

There is a genuine trade-off here, not just a promotional talking point. Separate structures can create information silos, where mine geology and exploration geology do not share subsurface data efficiently, and running two teams carries duplicated overhead. Priority conflicts also surface when aggressive drilling competes with development for infrastructure access.

For an investor weighing the upside case, the read is this: a CAD 49 million, six-rig campaign with its own management team is a commitment to discovery well beyond routine sustaining drilling. The dedicated budget tells you exploration is not being rationed to fund the mine build. Whether the two teams stay coordinated is the operational question to keep watching.

What the Champagne Zone grade-control results actually show

Start with the numbers. Hole PE-26-894 returned 110.05 g/t Au over 2.15 m, including a sub-interval of 233.96 g/t Au over 1.00 m at roughly 145 m vertical depth. Hole PE-19-47W1 intersected 76.51 g/t Au over 6.40 m (true thickness 4.20 m) at approximately 200 m depth.

Headline grade 233.96 g/t Au over 1.00 metre, from grade-control drilling within the active development footprint.

Grades like these would be notable from any drill programme. What makes them qualitatively different evidence is the context in which they were taken.

This is grade-control drilling, not step-out or resource-extension work. The distinction matters. Step-out drilling probes outward from a known zone to test whether mineralisation continues; grade control samples material already inside the development footprint, at tight spacing, to characterise what the mine will actually encounter. That puts these intercepts closer to real mining grades than exploration results typically get at this stage.

Here are the key intercepts from the current grade-control programme:

These results sit on top of an already meaningful resource. The Champagne Zone’s May 2025 update reported measured and indicated resources of 831 koz Au at 16.20 g/t in 1.594 Mt, a 172% increase in M&I ounces and a 43% grade increase versus the prior year’s estimate.

The Champagne Zone is the foundation of the Phase 1 feasibility study, so grade-control results feed directly into the economics that will underpin any production decision. For an investor assessing the known resource base rather than the speculative upside, this is where the highest-confidence evidence lives. Several of these individual intercepts remain company-reported and not independently verified, so weight them as grade-control data points rather than confirmed reserve figures.

The National Instrument 43-101 disclosure standards govern how resource classifications such as Measured, Indicated, and Inferred must be reported, and require a Qualified Person sign-off before any mineral resource estimate can be disclosed to the market; the Champagne Zone’s 831 koz M&I figure sits within that framework.

The Rosé Zone discovery and what a new find beneath the ramp means

The Rosé Zone begins approximately 165 metres directly below the active development ramp, the same ramp being built for the bulk sample and future mine. That single fact changes the economics of the discovery before any grade is considered, because accessing it later would leverage infrastructure already under construction rather than requiring a separate access development.

Here is what the zone looks like as currently defined:

• Announced 10 September 2026
• Located roughly 165 m beneath the active development ramp
• Traced over approximately 275 m of vertical extent and 70 m of strike length
• Open in multiple directions, including at depth

The discovery intercepts are early but supportive. Hole PE-25-878 returned 10.94 g/t Au over 1.20 m, including 21.22 g/t Au and 4.30 g/t Ag over 0.55 m at approximately 280 m depth. Other holes in the zone returned similar high-grade sub-intervals at comparable depths.

The most important data point for the upside case is the deepest hole. PE-26-950 reached 410 metres and encountered visible gold, with the zone still open below that. Visible gold at depth is not a resource, but it is a credible signal that the open-at-depth call is more than a standard disclaimer.

How deep Abitibi systems tend to behave

To judge whether “open at depth” carries real weight here, it helps to know how Abitibi gold systems behave vertically. These deposits sit within crustal-scale shear zones, long-lived faults that focus mineralising fluids over great vertical distances.

The analogues are instructive. Agnico Eagle’s LaRonde mine has produced from lenses approaching 3 km depth, and Kirkland Lake’s Macassa mine hosts high-grade zones beyond 2 km. The Champagne Zone itself has been confirmed to at least 1.6 km depth, which places the Rosé Zone’s current 410 m well within the range where continuity remains plausible.

The Abitibi Greenstone Belt geology that makes these depths productive traces back to an ancient volcanic arc sequence where crustal-scale shear zones have concentrated gold over billions of years, a setting that explains why analogue mines like LaRonde and Macassa have sustained high-grade production well beyond 2 km.

The risks at depth are real, though. The brittle-ductile transition can disrupt structural continuity, drilling costs rise, and fewer pierce points mean less confidence per metre. For investors comparing discovery-stage catalysts, the specific thing to watch is whether upcoming Rosé Zone drill results confirm continuity between the shallower intercepts and that visible gold at 410 m. CEO Victor Cantor has indicated deep exploration drilling from underground infrastructure is anticipated within 3-4 years of production start.

The Ontario program and why VMS targets carry a different risk profile

The Ontario side of the property is a genuinely different exploration thesis, not an extension of Perron. Two rigs are turning year-round on early-stage targets, hunting for volcanogenic massive sulphide (VMS) mineralisation and associated gold. This work sits well behind the Quebec programme in maturity.

The geology explains why the risk profile differs. VMS deposits form as stratiform to lensoid accumulations of massive sulphides on ancient seafloors, and they are notoriously irregular, with thickness and grade changing rapidly over short distances. Gold within VMS is often tied to specific sulphide assemblages, which produces strong local grade variability. Converting early high-grade hits into a resource typically demands tight-spaced drilling and detailed 3D modelling.

VMS deposit geometry introduces conversion risk that orogenic gold investors are typically unaccustomed to: the same stratiform setting that can host massive sulphide lenses at very high grades also produces rapid lateral and vertical grade changes that require dense drilling grids before resource confidence reaches the Indicated category.

Orogenic gold, the Quebec model, behaves more predictably. The mineralisation sits in steep shear corridors that can be traced over hundreds of metres to kilometres, giving each new hole a clearer structural framework to work within.

The contrast is easier to see side by side:

VMS at scale can be transformational; the Kidd Creek and Noranda camps in the Abitibi show what a major VMS discovery can represent. But that upside is front-loaded with geological and geophysical uncertainty, which is normal for early-stage VMS and higher than what Perron investors are used to evaluating.

The read for an investor is a matter of calibration. If and when Ontario assays arrive, they should be judged against different continuity and conversion expectations than the Champagne Zone results. No Ontario assay figures are available in the current accessible sources, which is itself worth flagging: the programme is genuine optionality, but it is optionality on a longer clock.

What the exploration budget scale signals about Phase 2 ambition

Shift from the geology to the strategy, and the size of the exploration commitment starts to look like a bet with a specific target. The CAD 49 million across 2026 and 2027, running at roughly CAD 2 million per month in 2027, is not routine sustaining drilling. It is scaled to answer a question that sits about six years downstream.

That question is Phase 2. The company has outlined an on-site mill at 2,000 tonnes per day, projected for roughly 2032-2033, and its economics depend on the resource base being large enough to justify the capital. The funding logic sharpens the point: Phase 2 capital is expected to come from Phase 1 free cash flow.

Read together, this means the current drilling programme is doing double duty. It extends the Champagne Zone resource in the near term, but it is also assembling the resource case that either does or does not support the mill build a decade out. Committing this much to exploration while a feasibility study is already in hand signals that management treats the Phase 2 resource case as unsettled, not assumed.

The market environment reinforces why news flow matters. Capital for Abitibi juniors is bifurcated toward advanced projects and producers, and sustaining a stream of high-grade intercepts is the main mechanism for holding market attention and access to specialist and flow-through capital.

Junior miner capital access in the current environment remains concentrated at the advanced-project and producer end of the market, which is precisely why a sustained stream of high-grade intercepts carries strategic weight beyond the geological signal: it maintains the news flow that keeps specialist and flow-through investors engaged across a multi-year development cycle.

On deep drilling timing Deep exploration drilling directly from underground infrastructure is anticipated within 3 to 4 years of production startup, with Champagne Zone mineralisation already confirmed to at least 1.6 km depth.

For investors, the catalyst sequence to track over the coming years runs roughly as follows:

1. Champagne Zone resource growth from ongoing grade-control and step-out drilling
2. Rosé Zone resource conversion as drill coverage expands
3. First Ontario VMS assay results and geophysical interpretation
4. Completion of the Phase 1 feasibility programme and development milestones
5. A Champagne resource base large enough to trigger the Phase 2 mill decision

Each major intercept or new zone is therefore also a data point on the resource growth trajectory that determines whether the larger project economics are achievable.

Reading the exploration upside without the promotional layer

Strip away the enthusiasm and the scepticism, and what the evidence actually supports as of September 2026 is layered. The Champagne Zone is a high-grade resource with grade-control confirmation. The Rosé Zone is a credible new find with rare infrastructure proximity but limited drill coverage. The Ontario VMS programme is frontier optionality with no published assays yet. Over all of it sits a substantial, committed drilling budget.

Quebec gold corridor drilling across the wider Abitibi in 2026 has seen multiple companies targeting shear-hosted deposits with similar structural settings to Perron, providing a comparative dataset for assessing whether grade-control results in the range of 52-110 g/t represent genuinely exceptional mineralisation or a regional characteristic of the belt’s more active structural corridors.

The three tiers are best understood on separate terms:

• Champagne Zone: most advanced, most investment-grade. 831 koz M&I at 16.20 g/t, grade-control confirmed, feeding the Phase 1 feasibility study directly.
• Rosé Zone: credible catalyst with infrastructure proximity. Defined to roughly 275 m vertical, open at depth, near-term news flow the key variable.
• Ontario VMS: genuine but early optionality. Two rigs turning, no published assays, longer time horizon and higher risk tolerance required.

The variables that will decide whether the upside develops are specific and knowable: Rosé Zone assay continuity in the next round of results, the first Ontario VMS intersections and their geophysical framework, and whether the Champagne Zone resource trajectory reaches a Phase 2-supporting base. The total Perron property already carries 1.615 Moz Au M&I at 6.14 g/t, which is the platform the rest is building on.

The honest read is that the next 12-18 months of news flow from the six-rig programme will be the clearest signal yet on whether the 570 km² land package is a genuine multi-million-ounce platform or a high-grade but structurally limited project. Track the zone-level geometry and continuity more than any single intercept grade.
