Banyan Gold Hits 13 g/t in Frozen Swamp Gap Between Deposits

Banyan Gold Corp. has hit 13.03 g/t gold over 14.2 metres in a corridor between two of its own deposits that had never seen a drill bit, because the ground is swampy and can only be reached when it freezes solid in winter. The hole came from Powerline North, in the untested gap separating the Airstrip and Powerline deposits at the AurMac project in Yukon, Canada.

Two stories are now running at the company on different clocks. The gap-zone result carries immediate weight for how the pit gets designed ahead of a maiden economic study; a second set of results, from a wholly owned greenfield site called Nitra, is earlier stage but hints at a far larger prize, with nine of eleven targets still unreported.

Both landed inside the same stretch of the calendar, and that compression is the point. Read together, these results tell you Banyan is no longer a single-deposit, low-grade tonnage story. This is a company discovering high-grade optionality inside its existing resource and across a district it has barely tested, all while a funded scale-up takes shape. What follows below is not a routine drilling update.

Why drilling a swamp changed the picture at AurMac

For most of the AurMac drill programme, the strip of ground between the Airstrip and Powerline deposits was simply a blank. Swampy terrain made it impossible to move rigs onto the corridor during the normal field season, so it stayed untested year after year, drillable only when winter froze the ground hard enough to support the equipment.

When Banyan finally punched holes into that gap, the ground did not read like waste. The 17 August 2026 release, titled “Banyan Gold Intersects 13.03 g/t Au over 14.2 m at Powerline North, AurMac, Yukon, Canada,” reported the following:

• Headline intercept: 13.03 g/t Au over 14.2 m at Powerline North
• Internal high-grade sub-interval: 142.70 g/t Au over 1.0 m
• Location: the previously untested corridor between the Airstrip and Powerline deposits
• Access constraint: winter-only, due to swampy terrain

That is the pivot. A structural blind spot in the resource model just returned high-grade gold, and CEO Tara Christie linked it directly to how the future mine could be built.

“This high-grade gap-zone intercept could alter pit sequencing and potentially define a new starter pit,” Christie indicated in connection with the result.

Here is what that means for you as an investor. A new high-grade domain sitting between two existing pit shells compresses the distance between them and raises the prospect of a single, more efficient pit rather than two separate ones with duplicated haul ramps and infrastructure.

A starter pit built around high-grade ore delivers above-average head grades in the first years of production, which is exactly what improves payback and internal rate of return in an economic study.

The current Mineral Resource Estimate, effective 15 May 2026, defined the project as a large low-grade base: 3.639 Moz Indicated at 0.68 g/t and 4.985 Moz Inferred at 0.58 g/t. If the gap zone holds in follow-up drilling, the economics that flow into the Preliminary Economic Assessment could look materially different from what that resource alone implies.

Economic feasibility studies translate resource models into investment decisions by combining grade assumptions, strip ratios, capital costs, and metal prices into NPV and IRR figures; the gap zone’s potential to shift starter-pit grade assumptions is significant precisely because early-year head grades carry disproportionate weight in those calculations.

The Powerline results in context: what the broader 2026 programme is delivering

The gap-zone hole was not a lone lucky strike. It sits at the top of a run of high-grade results across the Powerline corridor through 2026, and the sequence is what turns exploration excitement into resource-model confidence.

The pattern started early. On 17 June 2026, hole AX-26-853 returned 5.58 g/t Au over 21.7 m at the newly discovered Powerline Southwest zone, including 13.00 g/t Au over 9.2 m and a very high-grade internal interval of 62.66 g/t Au over 1.8 m. On 6 July 2026, the company reported it had expanded the high-grade domains at Powerline further.

The gap-zone intercept followed in August. Then September added the strongest evidence yet that these are not isolated pods but a coherent high-grade system.

Behind the drill bit, the programme itself has scaled hard. Banyan announced a fully funded 40,000+ m campaign in February 2026, expanded it past 60,000 m by mid-year, and moved to six rigs in autumn 2026.

Scaling from 40,000 m to 60,000 m and then to a planned 120,000 m in 2027 is only executable if the logistics of gold drilling in Canada, which are shaped by season length, rig availability, and permitting lead times particular to northern jurisdictions, can be managed at pace.

For you, the sequence matters more than any single number. One intercept is noise; a consistent pattern of high-grade hits across multiple holes and sub-zones is what drives resource upgrades and lifts the grade assumptions feeding the PEA.

The most recent release: September 2026 Powerline update

The 17 September 2026 Access Newswire release, “Banyan Gold Intersects 1.05 g/t Gold over 52.8 metres and Bonanza-Grade Gold at Powerline Deposit,” delivered two contrasting signals.

Hole AX-26-892B returned 1.05 g/t Au over 52.8 m, a broad, consistent width. Hole AX-26-891 delivered a bonanza-grade interval of 149.14 g/t Au over 0.4 m within a much larger envelope of 0.56 g/t Au over 169.2 m.

That combination is telling: bonanza-grade gold sitting inside a wide, low-grade envelope points to a system with both bulk tonnage and rich internal domains.

Nitra: two discoveries from two targets, nine still to report

Two targets drilled, two discoveries. That is the strike rate Banyan has posted at its wholly owned Nitra project, a greenfield site roughly 25 km west of AurMac on claims carrying no underlying royalties.

Drilling started on 15 June 2026 across an approximately 830 km² combined land package, with the 2026 Nitra campaign covering around 7,500 m and testing eleven regional targets. The 28 July 2026 release reported the first two:

• Roaring Fork Zone: 1.62 g/t Au over 5.0 m, including a sub-interval of 17.80 g/t Au over 0.4 m
• Seattle Creek Zone: 0.91 g/t Au and 27.01 g/t Ag over 12.1 m, including 5.70 g/t Au and 544 g/t Ag over 0.5 m

Then comes the part that keeps this story open. As of 26 September 2026, results from only two of the eleven targets had been reported. Nine remain unannounced, and the 2027 programme already plans a further 20,000 m at Nitra.

Two discoveries from the first two holes tested at a barely explored site tells you the wider district holds mineralising potential the AurMac resource does not capture. Nine unreported targets means this thread is structurally open-ended in a way few junior programmes can claim at the same stage.

Nitra is not just a standalone exploration story. It is a potential multiplier on AurMac’s mill economics, and Christie has put numbers on the lever.

“A satellite deposit of 200,000 to 500,000 ounces grading above 1 g/t within trucking distance could materially improve the grade and production rate of a future AurMac operation,” Christie indicated.

For you, that is the practical stake. A royalty-free, high-grade satellite feed within trucking distance could raise the average head grade of a future AurMac operation without the capital of a second processing plant.

PEA trajectory, financing, and the scale-up taking shape for 2027

Drill results tell you what is in the ground. The corporate moves tell you whether the company can afford to develop it, and here the signals point one way.

The current Mineral Resource Estimate, effective 15 May 2026, defined the project as a large low-grade base: 3.639 Moz Indicated at 0.68 g/t and 4.985 Moz Inferred at 0.58 g/t, and the PEA valuation hurdles that study must clear have attracted dedicated analysis given where Banyan’s market capitalisation now sits.

In September 2026, Banyan completed a C$58 million financing that included participation from Franco-Nevada. That involvement is not routine for a junior at this stage; it tells you a sophisticated royalty and streaming counterparty ran its own due diligence and concluded the project merited capital at scale.

A separate milestone followed. Banyan was added to the GDXJ (VanEck Junior Gold Miners ETF) index, effective 21 September 2026, a liquidity and visibility marker distinct from the raise.

The corporate scorecard now reads:

• Financing: C$58 million, September 2026
• Strategic participant: Franco-Nevada
• Index inclusion: GDXJ, effective 21 September 2026

Three forward-looking milestones set the pace from here:

1. PEA completion, targeted H2/Q4 2026, with consultants engaged on 7 July 2026
2. The six-rig autumn 2026 programme, currently scaling up
3. The 2027 programme of 120,000 m total (100,000 m at AurMac plus 20,000 m at Nitra), with eight rigs planned from mid-January 2027

For you, the financing and index inclusion remove two of the most common junior red flags: treasury adequacy and institutional liquidity. The 2027 scale signals management is committing capital at a rate consistent with PEA advancement and resource conversion, not just open-ended exploration.

What the gap zone and Nitra together signal about Banyan’s next twelve months

Take the two threads together and a single read emerges. Banyan holds a large low-grade resource base, and it is now discovering high-grade optionality both inside the existing deposit envelope and across a district it has scarcely tested.

The gap zone feeds the near-term catalyst directly. If follow-up drilling confirms continuity, the corridor enters the resource model ahead of the PEA and could shift the starter-pit assumptions underpinning the study’s economics.

Nitra runs on a longer clock. Its nine unreported targets generate news flow that extends past the PEA timeline, giving investors a parallel exploration story to track separately from the AurMac development pathway.

The closest structural analogue is Agnico Eagle’s Meadowbank-Amaruq complex in Nunavut, where a high-grade satellite was trucked to an existing mill, extending mine life and lifting the production profile. That is the template Banyan’s hub-and-spoke ambition is chasing.

For readers wanting to understand the structural reasons why projects at Banyan’s stage trade at discounts to in-situ value, our full explainer on junior mining valuation gaps covers the historical, liquidity, and sentiment factors that have kept junior gold equities depressed relative to their resource base across multiple cycles.

Risks and the confirmation milestones to watch

None of this is settled, and the risks are specific to this stage:

• Gap-zone continuity can only be tested in winter, meaning the next drilling window is the 2027 winter programme
• Nitra’s nine remaining targets are early-stage, and individual intercepts do not establish resources; results will arrive as news flow through late 2026 and into 2027
• The PEA is a study with sensitivity ranges, not a construction commitment

For you, the practical work is watching how each thread resolves. A confirmed high-grade domain, a two-for-two greenfield strike rate, a funded 120,000 m 2027 programme, and a PEA nearing completion place Banyan at an unusually active inflection point over the next six to twelve months.
