A fresh set of drill results from British Columbia’s Golden Triangle has put Goliath Resources’ Surebet discovery back in focus. The company reported that hole GD-26-436 returned 19.51 grams per tonne gold-equivalent over 8.32 metres, part of a much broader 35.7-metre interval grading 7.38 g/t AuEq at its wholly owned Golddigger Property. The result is notable not simply because of the headline grade, but because it arrived alongside additional mineralized intercepts as Goliath works through a fully funded, approximately 50,000-metre 2026 drilling campaign. Silver makes an unusually large contribution to the standout interval, while visible gold and sulphide mineralization continue to appear across the wider system. Even so, Surebet remains an exploration-stage discovery, making drilling continuity, metallurgy and eventually a formal mineral resource estimate crucial measures of what the project may ultimately become.
The Headline Hole Delivered More Than One High-Grade Interval
Hole GD-26-436 produced the strongest result in Goliath’s August 21 release. The company reported 7.38 g/t gold-equivalent across 35.70 metres from 41.30 metres downhole, including the 8.32-metre interval averaging 19.51 g/t AuEq. Within that narrower section was an even richer 3.10 metres grading 46.49 g/t AuEq. Another part of the hole returned 14.70 g/t AuEq over 2.95 metres, while a separate five-metre section averaged 8.49 g/t AuEq. The combination gives the hole more context than the 19.5 g/t headline alone: elevated grades occurred at several points within a substantially wider mineralized envelope.
The geological description is equally important. Goliath reported quartz-sulphide stockwork and breccia hosted in sandstone, along with visible gold, native silver, galena, sphalerite, pyrrhotite and chalcopyrite. The 562-metre-long hole was drilled from an elevation of 1,485 metres, but its headline mineralization was encountered close to the collar. Goliath describes the 35.7-metre interval as near-surface mineralization. For an explorer, that combination of width, grade and relatively shallow occurrence provides a useful target for additional drilling designed to test whether comparable mineralization persists between neighbouring holes and farther along the structure.
Silver Makes the 19.51 g/t Gold-Equivalent Number Especially Interesting
The standout 8.32-metre interval is highly polymetallic. Its average assay was 3.74 g/t gold, 975.34 g/t silver, 0.03% copper, 0.19% lead and 0.20% zinc. In other words, the reported 19.51 g/t AuEq should not be interpreted as 19.51 grams of physical gold in every tonne of rock. Gold-equivalent calculations convert the theoretical value of several metals into the equivalent amount of one reference metal, allowing polymetallic intervals to be presented with a common comparison figure.
Silver provides most of the uplift in this particular interval. Using the commodity prices specified by Goliath in its August release, 975.34 g/t silver contributes roughly 15.65 g/t of the calculated gold-equivalent value before the smaller copper, lead and zinc credits are included. That means about four-fifths of the reported 19.51 g/t AuEq comes from silver rather than gold itself. The 3.10-metre subsection is even more striking, carrying 6.98 g/t gold and 2,447.25 g/t silver, alongside smaller base-metal values, for 46.49 g/t AuEq. Goliath explicitly states that its AuEq figures are for comparative purposes and do not incorporate metallurgical recovery factors, an important qualification when interpreting the numbers.
Reported Drill Length Is Not the Same Thing as True Mineralized Width
Drill results can look deceptively simple when reduced to grade multiplied by metres, yet the orientation of a drill hole relative to a vein or mineralized structure matters enormously. Goliath states that the intervals in its latest release are reported as drill lengths and that estimated true widths are approximately 80% to 90% of those lengths. That qualification means the 8.32 metres in the headline is the length encountered along the drill core rather than a direct measurement of the mineralized body perpendicular to its boundaries.
The company also says interval boundaries were selected using both assays and geological observations, including the extent of mineralized veining. Individual assay samples were combined using length-weighted averages, a standard approach that prevents a short sample from carrying the same mathematical influence as a much longer one. GD-26-436 began intersecting its broader reported interval at only 41.30 metres downhole, with the headline 8.32-metre subsection running from 54.00 to 62.32 metres. Those depths help explain the company’s description of the intersection as near surface. Ultimately, however, closely spaced drilling and geological modelling are what establish the geometry and continuity needed to convert impressive individual intersections into a dependable three-dimensional picture.
Several Other Holes Strengthen the Context Around GD-26-436
The August 21 results were not limited to a single standout hole. GD-26-426 cut two neighbouring mineralized splays in the Surebet Zone. The first returned 2.81 g/t gold over nine metres, including 5.18 g/t over 4.50 metres. A second interval averaged 4.22 g/t gold over 5.80 metres and included three metres at 7.85 g/t. Goliath reported those results on a gold-only basis because complete gold-equivalent assays were still pending. That distinction matters when comparing them with GD-26-436, where silver and base-metal assays were already incorporated.
Another hole, GD-26-431, tested the sediment-hosted Eldorado Zone and returned 3.07 g/t gold over 11.90 metres, including 5.83 g/t over 5.95 metres and 11.42 g/t over 2.90 metres. Meanwhile, updated multi-element assays for GD-26-424 produced 10.90 g/t AuEq over six metres, including 35.65 g/t AuEq across 1.82 metres. GD-26-414 returned 1.92 g/t AuEq across 16.45 metres. Taken together, the batch illustrates the variability typical of an evolving mineral system: different holes are intersecting different widths, grades and geological settings rather than producing a uniform sequence of identical high-grade intervals.
The 2026 Drill Campaign Is Already Well Beyond 30,000 Metres
Goliath began the 2026 field season with an approximately 50,000-metre program and seven drill rigs planned for the Surebet system. By the August 21 update, the company said it had completed 52 of 98 planned holes representing 31,994 metres of drilling. All 52 holes had encountered quartz-sulphide mineralization, while visible gold had been observed in multiple veins and shear zones in 33 of those holes. Assays, rather than visual observations alone, remain the measurement that ultimately establishes grade.
The scale of the campaign is important because Surebet is no longer being evaluated with a handful of isolated discovery holes. Goliath completed 64,364 metres of drilling during 2025 alone and had surpassed 156,000 metres at Surebet before the current season. The 2026 program is intended to extend the Surebet, Bonanza and Golden Gate zones laterally and at depth while also testing geological targets associated with a potential intrusive feeder. Goliath is also using directional drilling on selected pads, creating several branches from one deeper “mother” hole. That method can reduce duplicated drilling through barren upper rock and allows multiple targets to be reached from the same collar area, potentially improving both efficiency and targeting precision in mountainous terrain.
Surebet Is Developing Into a Complex Stack of Mineralized Zones
Goliath’s geological model currently divides the discovery into five main mineralized systems: Bonanza, Surebet, Golden Gate, Whopper and Eldorado. Collectively, the company models 46 gold-rich lodes or veins, in addition to mineralized Eocene-aged dykes. The overall Surebet discovery footprint is described as approximately 1.8 square kilometres. High-grade mineralization has been identified in sediment-hosted quartz-sulphide breccias and stockworks, veins within volcanic rocks, and intermediate-to-felsic dykes, giving exploration geologists several different host environments to follow.
That setting sits within a much larger regional story. The British Columbia Geological Survey describes the Golden Triangle as containing many of the province’s major gold, silver and copper deposits within Stikinia, with numerous important deposits associated with the Hazelton Group and related intrusions. Goliath says its property lies within the Eskay Rift and within three kilometres of the geological contact commonly called the “Red Line,” separating Triassic Stuhini rocks from younger Jurassic Hazelton rocks. The company controls approximately 56 kilometres of that trend. Proximity to favourable regional geology does not guarantee an economic deposit, but it helps explain why this part of northwestern B.C. continues to attract intensive exploration spending.
Visible Gold Has Become Common, but Assays Still Matter More
One of Surebet’s more unusual statistics is the frequency with which visible gold has been logged in drill core. Goliath reports that 355 of 386 holes drilled between 2021 and 2025 contained gold visible to the naked eye, representing roughly 92% of those holes. The company also says all pre-2026 drill holes at the discovery intersected gold mineralization, with more than 1,500 drill-hole pierce points included in its geological database. Roughly 77% of those pierce points are spaced between 25 and 50 metres, providing a substantially denser drilling framework than was available during the project’s first discovery seasons.
Visible gold makes for compelling core photographs, but it should not be confused with a quantitative assay result. A small coarse grain can be visually dramatic without representing the average grade of a broader interval, while fine gold can produce strong assays without being obvious in hand specimen. That is why the continued combination of visual logging, structural measurements and laboratory analysis matters. At Surebet, the repetition of mineralized intercepts across hundreds of holes is becoming more informative than any single occurrence of visible gold. The key question is whether this growing dataset can eventually support robust estimates of tonnage, grade distribution and geological continuity.
Early Metallurgical Testing Produced High Gold Recoveries
Drilling establishes where metals occur, but metallurgy begins to answer a different question: how much of those metals can potentially be recovered from the rock. Goliath released preliminary metallurgical results in 2023 from a composite made using quartered drill core taken from 32 mineralized intercepts from its 2022 campaign. Gravity treatment followed by flotation recovered 92.2% of the gold, 86.5% of the silver, 94.2% of the lead and 96.9% of the zinc in that test program. The combined concentrate represented 11.9% of the original sample mass.
Gravity concentration alone recovered 48.8% of the gold and 10.3% of the silver at a relatively coarse 327-micrometre grind. Goliath reported that cyanide leaching was not required to achieve the gold and silver recoveries demonstrated in that particular test program, while the final gravity-plus-flotation concentrate contained 73.2 g/t gold, 1,346 g/t silver, 10.36% lead and 7.69% zinc. Those numbers are encouraging, but they remain preliminary. A composite sample cannot demonstrate how every mineralized zone will behave at commercial scale. Additional variability testing, process design, operating-cost work and engineering would be needed before metallurgy could be translated into a mine plan.
Ownership and Location Add Important Context to the Discovery
Goliath strengthened its ownership position earlier in 2026. In March, the company issued three million shares to earn the remaining 51% interest in Golddigger, taking its ownership to 100%. It also reduced an underlying net smelter return royalty from 3% to 2%. The wider property package covers approximately 91,518 hectares, or about 226,146 acres, giving the explorer considerably more ground than the immediate 1.8-square-kilometre Surebet discovery itself.
Location is another part of the project’s appeal. Goliath describes Golddigger as being adjacent to tidewater, with a roughly 190-kilometre barge route to Prince Rupert. Its latest project description places the Dolly Varden Silver Mine Road approximately seven kilometres east of Surebet, the Alice Arm barge landing about 18 kilometres to the south and high-tension power roughly 25 kilometres east. The nearby Kitsault area also has a long mining history documented by the B.C. Geological Survey. More broadly, the provincial geological survey notes that more than 150 mines have operated across the Golden Triangle since prospecting began in the late 19th century and that improved infrastructure has helped stimulate modern exploration. Existing regional infrastructure can reduce logistical barriers, although a discovery still requires its own detailed access, permitting and development studies.
Strong Assays Still Leave Major Questions to Be Answered
Goliath describes a detailed quality-control process for the new results. Drill core is logged, measured and cut lengthwise, with one half retained while the other is submitted for analysis. Certified reference materials, blanks and duplicate samples are inserted at a stated rate of 10%, with additional blanks placed after samples containing visible gold or conspicuously high sulphide content. Gold is analyzed using MSALABS’ PhotonAssay method in Prince George, while multi-element work is conducted using four-acid digestion and plasma spectroscopy. MSALABS lists its Prince George laboratory as accredited to ISO/IEC 17025 for applicable testing methods. The technical disclosure was reviewed and approved by Rein Turna, P.Geo., Goliath’s designated Qualified Person.
Those safeguards strengthen confidence that the reported assays represent the submitted core, but they do not answer the larger economic questions. Surebet does not yet have a published mineral reserve, and Goliath has described its current drilling as work toward a future mineral resource. Its amended property agreement requires the company to publish a mineral resource estimate by June 1, 2030. Before any mine-development conclusion can be drawn, the project would need resource modelling and potentially economic, engineering, environmental and permitting studies. For now, 19.51 g/t AuEq over 8.32 metres is best viewed for what it is: a strong exploration result within an increasingly well-drilled, polymetallic system that still has important technical milestones ahead.
