TORONTO, Sept. 10, 2026 (GLOBE NEWSWIRE) -- Goliath Resources Limited (TSX-V: GOT) (OTCQX: GOTRF) (FSE: B4IF) (the “Company” or “Goliath”) is pleased to report assay results for drill holes GD-26-417, GD-26-425, GD-26-440, GD-26-462, confirming the presence of the volcanic Wedge Zone in the western, northeastern and southern parts of the mineralized system. The volcanic Wedge Zone is located between the structural intersection of the Bonanza and Golden Gate Zones connecting them that could significantly expand the volume of known mineralization on its 100% owned Golddigger Property (the “Property”), Golden Triangle, British Columbia.

Mr. Roger Rosmus, Founder & CEO of Goliath states: “We are pleased to see the expansion of the mineralized Wedge Zone to the west, southwest and northeast. This is another important piece of the bigger picture that is unfolding at the Surebet Discovery as we continue to test for the Motherlode Causative Intrusive source. Based on these positive results, there appears to be an opportunity to add significant volumes of mineralization to the Surebet system, inclusive of the 900 meters of volcanics untested with the drill bit that separate domains discovered this year in the West and Southwest; see Figure 1 above. With a targeted 50,000 meter drill program still underway, we are adding many more holes daily to the lab pipeline that should provide a steady flow of assay news into the new year”.

Drill hole GD-26-462 intersected 26.80 g/t AuEq over 2.30 meters within 14.28 g/t AuEq over 4.32 meters in the Wedge Zone located in the Surebet system expansion to the Northeast. This interval consists of frequent stockwork to sheeted mineralized veinlets associated with VG-NE. A second mineralized interval underlying the Wedge Zone was intersected in GD-26-462 that assayed 9.31 g/t Au over 3.65 meters, including 20.45 g/t Au over 1.65 meters composed of a broad quartz vein including semi-massive sulphides and VG-NE is part of the Golden Gate Zone.

Drill hole GD-26-417 intersected mineralization extending over 58.00 meters and grading 0.55 g/t AuEq, including 1.06 g/t AuEq over 9.00 meters. This interval is part of the volcanic Wedge Zone in the confirmed 540 meters expansion to the Southwestern part of the Surebet system and consists of frequent and tightly spaced quartz and calc-silicate veinlets where multiple VG-NE occurrences have been identified. A second mineralized interval was intersected below the Wedge Zone and assayed 2.22 g/t AuEq over 5.00 meters, including 9.30 g/t AuEq over 1.00 meter. This interval is part of the Golden Gate Zone and is composed of quartz-sulphide veining hosting VG-NE (Only Au assays previously reported, see news August 6, 2026).

Drill hole GD-26-425 intersected mineralization extending over 23.20 meters and grading 1.02 g/t AuEq, including 3.20 meters grading 4.16 g/t AuEq. Mineralization in this interval is part of a volcanic Wedge Zone that shows sheeted quartz-sulphide, calc-silicate veins and veinlets associated with VG-NE. A second Wedge Zone interval was intersected in GD-26-425 extending over 10.55 meters and grading 0.48 g/t AuEq, including 7.49 meters grading 0.56 g/t AuEq. Mineralization is distributed in sheeted to stockwork veinlets and widespread calc-silicate alteration stringers and patches.

Drill hole GD-26-440 intersected the Wedge Zone mineralization in the Northwest of the Surebet system extending over 24.97 meters and grading 0.66 g/t Au, including 7.05 meters grading 1.07 g/t Au (Au only; AuEq assays pending). Mineralization is hosted in tightly spaced sheeted quartz-sulphide vein sets hosted in the volcanics.

About Golddigger Property

The Golddigger Property is 100% owned and covers an area of 91,518 hectares in a highly prospective geological setting of the Eskay Rift, within 3 kilometers of the Red Line in the Golden Triangle of British Columbia. This area has hosted some of Canada’s greatest gold mines including Eskay Creek, Premier and Snip. Other significant and well-known deposits in the Golden Triangle include Brucejack, Copper Canyon, Galore Creek, Granduc, KSM, Red Chris, and Schaft Creek. Goliath controls 56 kilometers of the Red Line which is a geologic contact between Triassic age Stuhini rocks and Jurassic age Hazelton rocks used as key markers when exploring for gold-copper-silver mineralization.

The Surebet discovery has shown predictable continuity and good metallurgy with gold recoveries of 92.2% from gravity and flotation at a 327-micrometer crush, including 48.8% recovery of free gold from gravity alone (no cyanide required to recover the gold). The metallurgical testing completed to date shows no presence of deleterious elements (see news release dated March 1, 2023).

The Property is in a well positioned location in close proximity to the communities of Alice Arm and Kitsault where there is a permitted mill site on private property. It is situated adjacent to tide water with direct barge access to Prince Rupert (190 kilometers via the Observatory inlet/Portland inlet). The town of Kitsault is accessible by road (190 kilometers from Terrace, 300 kilometers from Prince Rupert) and has a barge landing, dock, and infrastructure capable of housing at least 300 people, including high-tension power.

Additional infrastructure in the area includes the Dolly Varden Silver Mine Road (only 7 kilometers to the East of the Surebet discovery) with direct road access to Alice Arm barge landing (18 kilometers to the south of the Surebet discovery) and high-tension power (25 kilometers to the east of Surebet discovery). The city of Terrace (population 16,000) provides access to railway, major highways, and airport with supplies (food, fuel, lumber, etc.), while the town of Prince Rupert (population 12,000) is located on the West Coast of British Columbia and houses an international container seaport also with direct access to railway and an airport.

Disclaimer

The reader is cautioned that grab samples are spot samples which are typically, but not exclusively, constrained to mineralization. Grab samples are selective in nature and collected to determine the presence or absence of mineralization and are not intended to be representative of the material sampled.

Quality Assurance / Quality Control (QA/QC) Protocol

Core Samples Handling & Sampling

Oriented HQ-diameter or NQ-diameter diamond drill core from the drill program is placed in core boxes by the drill crew contracted by the Company. Core boxes are transported by helicopter to the staging area and then transported by truck to the core shack. The core is then re-orientated, meterage blocks are checked, meter marks are labelled, Recovery and RQD measurements taken, and primary bedding and secondary structural features including veins, dykes, cleavage, and shears are noted and measured. The core is then described and transcribed in MX DepositTM data management software. Drill core containing quartz breccia, stockwork, veining and/or sulphide(s), or notable alteration is selectively sampled in lengths of 0.5 to 1.5 meters. Samples are selected from continuous intervals of mineralization and/or other relevant geological features, including shoulder samples that extend for 3 meters into adjacent unmineralized and/or unaltered country rock. Along barren core intervals devoid of mineralization or significant geological features, one 1 meter sample is collected every ten meters. Core samples are cut lengthwise in half: one-half remains in the box and the other half is inserted in a clean plastic bag with a sample tag. The bagged samples are then weighed and secured with a zip tie. Certified reference materials (CRMs), blanks and duplicates are added in the sample stream at a rate of 10%. To ensure analytical anonymity, CRM identification labels are removed prior to submission to the laboratory. Additional out-of-sequence blanks are introduced immediately following core samples that contain visible gold to the naked eye (VG-NE) or visibly high-grade sulphide mineralization.

Surface Samples Handling & Sampling

Grab, channels, chip and talus samples were collected by foot with helicopter assistance. Prospective areas included, but were not limited to, proximity to MINFile locations, placer creek occurrences, regional soil anomalies, and potential gossans based on high-resolution satellite imagery. The rock grab and chip samples were extracted using a rock hammer, or hammer and chisel to expose fresh surfaces and to liberate samples weighing anywhere between 0.5 and 5.0 kilograms. All sample sites were flagged with biodegradable flagging tape and marked with the sample number. All sample site locations were recorded using handheld GPS units (accuracy 3-10 meters) and sample ID, easting, northing, elevation, type of sample (outcrop, subcrop, float, talus, chip, grab, etc.) and a description of the rock were recorded on all-weather paper. Samples are then inserted in a clean plastic bag with a sample tag for transport and shipping to the geochemistry lab. QA/QC samples including blanks, certified reference materials, and duplicate samples are inserted regularly into the sample sequence at a rate of 10%.

Sample Analysis

All samples are transported in rice bags sealed with numbered security tags. The rice bags are transported from the core shacks to the MSALABS facilities in Terrace, BC. MSALABS is certified with both AC89-IAS and ISO/IEC Standard 17025:2017. The core samples undergo preparation via drying, crushing to ~70% of the material passing a 2 mm sieve and riffle splitting. The sample splits are weighed and transferred into plastic jars, each containing between 300 g and 500 g of crushed sample material. A 250 g split is pulverized to ensure at least 85% of the material passes through a 75 µm sieve. The crushed samples are transported to the MSALABS PhotonAssayTM facility in Prince George, where gold concentrations are quantified via photon assay analysis (method CPA-Au1). Samples that result in gold concentrations ≥5 ppm are analyzed to extinction. Photon assay uses high-energy X-rays (photons) to excite atomic nuclei within the jarred samples, inducing the emission of secondary gamma rays, which are measured to quantify gold concentrations. The assays from all jars are combined on a weight-averaged basis. Multielement analyses are carried out at the MSALABS facilities in Surrey, BC, where 250 g of pulverized splits are analyzed via IMS-230 and ICF6xx methods. The IMS-230 method uses 4-acid digestion (a combination of hydrochloric, nitric, perchloric and hydrofluoric acids) followed by inductively coupled plasma emission spectrometry to quantify concentrations of 48 elements. Samples with over-limit results for Ag, Cu, Pb and Zn undergo ore-grade analysis via the ICF-6xx method (where ‘xx’ denotes the target metal). This method employs 4-acid digestion followed by inductively coupled plasma emission spectrometry.

Gold Equivalent (AuEq) Calculation

Gold Equivalent (AuEq) values are provided for comparative purposes only and do not include metal recovery factors given that known metallurgical recoveries are only based on preliminary test work and may not be representative of all mineralization styles or zones. Gold Equivalent (AuEq) metal values are calculated using: 4,222.08 Au USD/oz, Ag 67.76 USD/oz, Cu 6.43 USD/lbs, Pb 1,967.13 USD/ton and Zn 3,578.25 USD/ton (updated on August 4, 2026) using the formula below

There is potential for economic recovery of gold, silver, copper, lead, and zinc based on other mining and exploration projects in the same Golden Triangle Mining Camp where Goliath’s project is located, such as the Homestake Ridge Gold Project (Auryn Resources Technical Report, Updated Mineral Resource Estimate and Preliminary Economic Assessment on the Homestake Ridge Gold Project, prepared by Minefill Services Inc. Bothell, Washington, dated May 29, 2020). Here, AuEq values were calculated using 3-year running averages for metal price, and included provisions for metallurgical recoveries, treatment charges, refining costs, and transportation. Recoveries for Gold were 85.5%, Silver at 74.6%, Copper at 74.6% and Lead at 45.3%. It will be assumed that Zinc can be recovered with Copper at the same recovery rate of 74.6%. The quoted reference of metallurgical recoveries is not from Goliath’s Golddigger Project, Surebet Zone mineralization, and there is no guarantee that such recoveries will ever be achieved, unless detailed metallurgical work such as in a Feasibility Study can be eventually completed on the Golddigger Project.

Reported Drill Intervals and Assays

Drill core intervals are reported as drill lengths, where the true width is estimated to be 80-90% of the length. The widths of the mineralized intervals were defined to reflect both the assay results and the mineralized veining observed in drill core. Veining constrains the local width of the mineralized zone, while assay results define the grade distribution within that zone. Reported intervals are therefore intended to represent geologically meaningful zone widths at the point of intersection.

The reported assays of drill intervals were calculated as length-weighted average grades using the individual sample assay results and their corresponding sample lengths. The average grade for each interval was determined by dividing the sum of the products of each sample grade and sample length by the total sampled interval length (Σ[grade × sample length] / Σ[sample length]). This method accounts for variations in sample length and provides a representative average grade over the reported interval.
