Goliath Resources Hits 31 g/t Gold as Bonanza Zone Grows 19%

#

Three new drill holes have pushed the Surebet Discovery’s Bonanza Zone 19% larger than it stood during the 2026 program, with the best interval returning 31.42 g/t gold-equivalent across a single metre of high-grade core, cut at a step-out 100 metres north of previously drilled ground.

Goliath Resources released the results on 18 September 2026, the newest assay batch from a 50,000-metre campaign that has already completed 97 holes across five target zones in British Columbia’s Golden Triangle. Full gold-equivalent assays have been reported for just 9 of those 97 holes so far, leaving the company perched on a deep backlog of pending results.

Here is what these three holes signal about where Surebet is heading, and why the sheer volume of outstanding assays matters as much as the intercepts already in hand. The intervals confirm a system still growing in every direction tested. The pipeline behind them decides whether 18 September proves representative or exceptional.

Three holes, one system growing in every direction

Start with the headline. Hole GD-26-442 returned 8.35 g/t AuEq over 4.15 metres, and inside that interval sat a single metre grading 31.42 g/t AuEq, the standout number of this release. The hole was drilled as a 100-metre northward step-out, landing in quartz-sulphide veins carrying naked-eye visible gold alongside galena, sphalerite, and pyrrhotite.

Highlight grade GD-26-442 returned 31.42 g/t AuEq over 1.00 metre, the strongest intercept in the September Bonanza Zone batch, from a hole positioned entirely outside previously drilled ground.

Hole GD-26-431 tested the western margin, and it did something worth noting: it hit twice in a single hole. The upper interval graded 9.12 g/t AuEq over 11.27 metres, including a core of 13.89 g/t AuEq over 7.14 metres. Deeper down, a Big Bulk Zone interval returned 4.70 g/t AuEq over 3.03 metres within a broader 1.08 g/t AuEq over 20.00 metres envelope.

That vertical stacking at the deposit’s edge tells you the layered vein architecture holds even where the system is thinning out laterally.

The third hole, GD-26-426, was a second step-out to the north. It returned 5.07 g/t AuEq over 3.91 metres inside a 2.93 g/t AuEq over 7.00-metre zone, cut through sheared quartz breccia with visible gold and base metal concentrations ranging from massive to stringer.

True widths are estimated at 80-90% of recorded drill lengths. The direction of these three holes, north, north again, and west, matters more than any single grade. Every new vector tested returned mineralisation, which means the deposit’s boundary remains undefined on multiple flanks. These were step-outs, not infill holes confirming known ground. The system is still opening up, not closing off.

How much bigger is the Bonanza Zone, and what does the footprint now look like?

The raw numbers first. The Bonanza Zone grew from 1.27 km² to 1.51 km², a 19% increase, driven by expansions in four directions:

• 750 metres to the southwest
• 160 metres to the northeast
• 100 metres to the west
• 100 metres to the north

That single-zone growth is the visible edge of a wider expansion. The total Surebet system now covers 2.01 km², up from 1.80 km², a 12% increase. Much of the remaining growth came from the Golden Gate Zone, which expanded from 0.85 km² to 1.17 km², a 38% jump reported concurrently.

A 2.01 km² system, with one zone up 38% and another up 19%, and fewer than 10 assay results in from a 97-hole campaign, tells you the size picture is nowhere near settled. Any resource framing anchored to older drilling is already working from a smaller map than the one that now exists.

The full Surebet system in 2026

Surebet is a stacked system, not a single vein. Geological modelling describes five gently dipping mineralised vein packages holding 46 gold-rich lodes, with 12 stacked high-grade veins extending roughly 1.2 km along strike and a vertical extent of 700 to 890 metres. A wider surface footprint here also projects additional depth potential.

The scale is what puts the numbers in context. In December 2025, Stifel published a preliminary exploration target of 4.3 Moz Au (22.6 Mt at 5.8 g/t Au), citing the deposit’s continuity, grade, and footprint. That estimate predates the footprint expansion reported this month.

One figure invites caution. Of 92 holes drilled by the 16 September update, 52 returned naked-eye visible gold, roughly 57%, against 92% in pre-2026 campaigns. That gap reflects the shift toward step-out drilling at the margins rather than infill in the proven core, so it reads as a function of where the rigs are pointed, not a fall in the system’s quality.

The 2026 campaign at scale: what 50,000 metres across seven rigs means for the assay pipeline

This is the largest programme in Goliath’s history: approximately 50,000 metres, seven drill rigs, fully funded, spread across five named zones.

1. Bonanza
2. Eldorado
3. Golden Gate
4. Surebet
5. Whopper

As of 16 September 2026, the company had completed 97 holes and drilled 45,616 metres. Every hole drilled in 2026 has intersected quartz-sulphide mineralisation, a 100% hit rate that continues the pattern set across more than 156,000 metres of pre-2026 drilling and over 1,500 pierce points.

Now the arithmetic that reframes everything. Complete gold-equivalent assays have been reported for only 9 of the 97 completed holes. That leaves results for roughly 88 holes still sitting in the laboratory.

The gap between holes completed and results reported is not unusual for campaigns of this scale; lab processing delays in junior mining programmes regularly run four to six months behind the drill bit, meaning the 88-hole backlog at Surebet reflects standard assay queue dynamics rather than any data quality concern.

The signal, not the deficit Approximately 88 holes carry pending assays. A campaign that has already returned 31.42 g/t AuEq within its first nine reported holes has the bulk of its data still to come.

For anyone tracking this story, that changes the reading. Fewer than 10% of the 2026 hole results have been assayed and released. Every headline to date is an early read on a much larger dataset, not a summary of the campaign. The news cycle here has considerably further to run.

What the Golden Triangle setting and site logistics add to this story

The geology explains why this ground is productive. The Golddigger Property spans 91,518 hectares and takes in 56 kilometres of the “Red Line” geological contact, sitting roughly 3 kilometres from that contact within the Eskay Rift. Goliath’s team describes the architecture as a reduced intrusion-related gold system, comparable to the Pogo Mine in Alaska, where a common magmatic source feeds veins across sedimentary, volcanic, and dyke-hosted settings.

Reduced intrusion-related gold systems, the structural category Goliath’s team applies to Surebet, are characterised by a common magmatic source feeding multiple vein sets across varied host rock types, which explains why mineralisation here appears in sedimentary, volcanic, and dyke-hosted settings rather than concentrating in a single lithology.

Metallurgy sets the floor on what a discovery can become, and Surebet’s early testing reads favourably. Combined gravity and flotation processing achieved strong recoveries, with no cyanide required and no harmful elements identified in preliminary work.

• Gold: 92.2%
• Silver: 86.5%
• Lead: 94.2%
• Zinc: 96.9%

Then there is access, which is where Golddigger separates from most remote Golden Triangle projects. The infrastructure already sits close to the discovery rather than a costly build away.

Put the two together and the implication is concrete. A 92.2% gold recovery from simple processing, alongside a permitted mill site already standing within the region, means Golddigger carries meaningfully lower development friction than most peers at the same resource-definition stage. Metallurgy and logistics rarely drive a news cycle, but they reduce two of the largest uncertainties that separate a spectacular drill hole from a working mine.

What comes next as the assay backlog clears

Three threads run through this update. The directional step-outs are still expanding the footprint. The 50,000-metre campaign is the largest Goliath has run. And roughly 88 holes of pending assays across five zones will ultimately decide whether 18 September was representative or an outlier.

That backlog is the main event, not background noise. Treat today’s intercepts as a calibration point, not a conclusion.

Context for the resource picture Stifel’s 4.3 Moz Au exploration target (22.6 Mt at 5.8 g/t Au) was published in December 2025, before the 19% Bonanza Zone expansion reported this month. Any resource-adjacent analysis that follows will be working from a larger map.

Three variables are worth watching from here: the remaining 2026 assay batches from all five zones, any revision to the Stifel target once the expanded footprint is modelled, and the company’s guidance on programme completion. On the regulatory side, British Columbia’s 2025 Mineral Claims Consultation Framework introduced a 20-day response window for First Nations consultation running alongside technical reviews. That is a development-stage variable, not a current barrier to the active drill programme. Goliath shares closed at approximately C$1.55 on the TSX Venture Exchange on 17 September 2026.

British Columbia’s consultation framework has introduced new procedural timelines at the claims level that sit alongside active drill programmes, and the broader processing backlog documented across the province adds regulatory context to any development-stage planning Goliath undertakes once the resource picture clarifies.
