Goliath Resources (TSXV: GOT; WKN A2P063) has once again released strong drill results from the Surebet discovery on its 100% controlled Golddigger Project in British Columbia’s Golden Triangle. The company reports ten additional drill holes with high-grade gold mineralization in the Bonanza and Surebet zones as well in a Eocene-aged Reduced Intrusion-Related Gold Dyke (RIRG).
The Surebet discovery currently covers an area of approximately 1.8 square kilometers with a system of 1.2 kilometers of stacked gold-bearing quartz-sulfide veins. According to Goliath Resources, 70 drill holes from the 2025 campaign are still being evaluated; in 55 of these holes, occurrences of visible gold to the naked eye (VG-NE) were identified up to 12 occurrences.
The results reported today from the 64,364-meter 2025 drilling campaign, which was entirely focused on the Surebet discovery, demonstrate once again that all drill holes completed to date at Surebet have intersected substantial quartz-sulfide mineralization, according to Goliath Resources.
Goliath Resources: Bonanza and Surebet Zones as well as the Eocene-aged RIRG Dykes remain open.
The key focus of the current announcement is the near vertical Eocene-aged RIRG Dykes. Also the Bonanza and Surebet Zones, two systems of stacked gold veins with different dip directions. The Bonanza zone consists of southeast-dipping veins that have now been traced for approximately 1.25 kilometers in an east-west direction and, according to the company, remain open. To the northwest, Bonanza can be traced for an additional 580 meters.
The higher-elevation Surebet Zone, a system of stacked, southwest-dipping veins, has been drilled for approximately 1.2 kilometers in a southwest-northeast direction and has also not yet reached its limits. According to Goliath Resources, a heat map of the distributed VG-NE occurrences shows a pronounced continuity of gold mineralization within the system.
Particularly noteworthy among the current results is drill hole GD-25-383, which averaged 7.28 g/t gold gold over 8.00 meters within an interval of 5.85 g/t gold over 10.00 meters in an Eocene-aged RIRG dyke at a drill depth of approximately 417 to 427 meters – about 500 meters above the valley floor. The section also includes 9.20 g/t gold over 5.92 meters and 12.75 g/t gold over 4.02 meters, each with multiple occurrences of visible gold. The company notes that the figures currently refer exclusively to gold grades; silver, copper, lead, and zinc values are still pending, as is an adjusted gold equivalent (AuEq). The thicknesses are described as approximate true thicknesses.
Drill hole GD-25-311 intersected two gold-rich veins: 15.13 g/t gold over 3.00 meters in the Bonanza Zone and 2.6 g/t gold over 4.01 meters in the Surebet Zone, both with visible gold in quartz-sulphide veins. Drill hole GD-25-370 intersected three gold-bearing veins in the Bonanza Zone, including up to 5.66 g/t gold over 5.05 meters, including 9.24 g/t gold over 3.05 meters from an area with pronounced quartz-sulfide mineralization and breccias.
Other reported intercepts include:
- GD-25-387: 4.05 g/t gold over 6.13 meters, including 5.36 g/t gold over 4.15 meters (Bonanza Zone).
- GD-25-385: 6.59 g/t gold over 4.00 meters, including 8.4 g/t gold over 3.13 meters (Surebet Zone).
- GD-25-398: 3.73 g/t gold over 6.77 meters with a sub-interval of 5.41 g/t gold over 4.64 meters, and a second interval of 2.68 g/t gold over 3.00 meters (Bonanza Zone).
- GD-25-378: 4.83 g/t gold over 4.54 meters, including 6.28 g/t gold over 3.44 meters (Bonanza Zone, with visible gold), and 2.49 g/t gold over 9.12 meters (Surebet Zone).
- GD-25-410: 4.18 g/t gold over 5.14 meters, including 5.28 g/t gold over 4.06 meters in the easternmost part of the Bonanza Zone, extending its strike to 1.25 kilometers.
- GD-25-356: 4.98 g/t gold over 3.87 meters (Bonanza Zone with visible gold).
- GD-25-376: 4.32 g/t gold over 4.20 meters, including 5.47 g/t gold over 3.20 meters (Surebet Zone with visible gold), and 3.55 g/t gold over 3.93 meters (Bonanza Zone).
All mentioned intervals are described by the company as approximate true widths; these are currently gold assays only.
Multiple Rock Types with Gold Mineralization at Surebet
Goliath Resources highlights that three rock types with gold mineralization have been identified at the Surebet discovery to date:
- shallow-dipping, gold-rich stacked quartz-sulfide breccias and stockwork veins,
- gold-bearing intermediate to felsic, Eocene-altered RIRG dykes,
- wide zones of calc-silicate altered breccia.
According to the company, all of these rock types contain visible gold – ranging from fine-grained to coarse-grained – and remain open at depth and laterally. Goliath Resources interprets the combination of RIRG dikes and vein networks as evidence of a deeper magmatic causative intrusive source (“mother lode”) feeding the extensive, approximately 1.8 km² gold-bearing system.

The 2025 Drilling Program
According to the company, Goliath Resources’ 2025 drilling campaign at the Surebet discovery comprised 64,364 meters of core drilling using nine drill rigs. Originally, 40,000 meters were planned, but the campaign was extended to systematically test the suspected causative intrusive gold source (“Motherlode”), the mineralized RIRG dykes, the known stacked veins, and extensions at depth and to the side.
Of the 110 holes drilled at Surebet in 2025, 83 contain VG-NE, representing approximately 76%. Extrapolated to the total drilling volume to date, VG-NE occurrences have been documented in 355 of 386 drill holes (approximately 92%). The total number of drill points (pierce points) within the Surebet area reached over 600, spread across twelve gold-mineralized veins.
According to the company, Goliath Resources’ Golddigger project covers 91,518 hectares in the Eskay Rift region of the Golden Triangle, approximately three kilometers from the geological “Red Line” – a frequently used guide structure in the exploration of high-grade gold-copper-silver systems. This region is home to well-known deposits such as Eskay Creek, Premier, and Snip, as well as larger projects such as Brucejack, KSM, and Red Chris. Goliath Resources controls approximately 56 kilometers of the “Red Line” contact zone.
According to an earlier company announcement, metallurgical tests on the Surebet mineralization have yielded combined gold recoveries of 92.2% from gravity and flotation at a grain size of 327 micrometers, of which 48.8% is free gold recovered by gravity separation alone, without the use of cyanide. No harmful elements have been detected in tests to date.
The project is conveniently located near the communities of Alice Arm and Kitsault, with access to an existing mill license on private land, tidal water access, road access, and high-voltage power lines.
Despite all the drilling and the successes already achieved, Goliath Resources still has work to do at Golddigger to expand the project towards the boundaries of the various gold mineralization zones. However, the Goliath team is more than enthusiastic that Surebet is a rare, high-grade gold discovery. Once the company of founder and CEO Roger Rosmus has all the results for 2025, the 3D model of the mineralization will be updated to best prepare for further drilling. All in all, it is believed that the Surebet discovery continues to show that it is likely to quickly become one of British Columbia’s most significant high-grade gold discoveries in a long time.
