TORONTO, Aug. 10, 2026 (GLOBE NEWSWIRE) -- Goliath Resources Limited (TSX-V: GOT) (OTCQX: GOTRF) (FSE: B4IF) (the “Company” or “Goliath”) is pleased to report assay results that confirm the expansion of the Golden Gate Zone to the Northeast by 320 meters of the previously known gold mineralization on its 100% owned Golddigger Property (the “Property”), Golden Triangle, British Columbia. The Golden Gate Zone remains open laterally and at depth.
Dr. Quinton Hennigh, Advisor to Goliath and Strategic Investor commented: “When I spoke with the Company prior to this drill season, they made it abundantly clear that a considerable number of the planned drill holes would test extensions of various lode systems at the Surebet Discovery. Given that there remains exceptional opportunity to grow the systems high-grade gold footprint, I was delighted to hear this. We are now seeing the impact of this strategic decision. Drill hole GD-26-420 encountered a 6.51 g/t AuEq over 5.73 meters across the Golden Gate lode in a position 320 meters northeast of its previous limit. I believe we will continue to see many further drill extensions over the course of the rest of the 2026 and the Surebet Discovery is only going to keep on growing with every drill program.”
Mr. Roger Rosmus, Founder & CEO of Goliath states: “Our team is performing like a well-oiled machine. The goal of this 2026 drilling campaign is expansion and the directional drilling being utilized is paying off with the step outs being successful. The 320 meter step out of Golden Gate to the northeast is one example and nice surprise along the way. It is worth noting the amount of visible gold to the naked eye in the drill holes since we started drilling the Surebet discovery is unique, as well high-grade gold systems are not known to have such large footprints. After over 400+ drill holes have been completed to date the system remains open laterally and at depth. Grass roots High -grade gold systems tend to get challenging to grow them. But Surebet discovery is the opposite, we are challenging the geology and having no problems growing the system with aggressive step outs. The cadence of drill holes getting to the lab for assays is ideal, and we hope to have plenty more assay results throughout the rest of the year and into 2027.”
Drill hole GD-26-414 intersected multiple mineralized intervals belonging to the Surebet and Golden Gate zones. The Surebet Zone interval assayed 2.81 g/t Au over 4.00 m, including 9.79 g/t Au over 1.00 m part of the Surebet Zone. This first interval contains multiple occurrences of VG-NE within quartz-sulphide veins and breccias with substantial calc-silicate alteration. The Golden Gate interval assayed 9.87 g/t Au over 5.00 m, including 65.65 g/t Au over 0.75 m part of the Golden Gate Zone. This second interval is characterized by several occurrences of VG-NE associated with quartz-sulphide veins containing lenses of semi-massive pyrrhotite, galena, sphalerite, and minor chalcopyrite.
Drill hole GD-25-420 intersected the Golden Gate Zone extending it by 320 meters to the Northeast. This interval assayed 6.51 g/t AuEq (6.16 g/t Au and 7.27 g/t Ag) over 5.73 m, including 13.49 g/t AuEq (12.79 g/t Au and 14.12 g/t Ag) over 2.73 m, including 36.27 g/t AuEq (34.43 g/t Au and 35.17 g/t Ag) over 0.97 m consisting of a series of broad quartz-sulphide veins hosted in volcanic rocks where VG-NE occurs in association with semi-massive pyrrhotite, sphalerite, pyrite and galena.
All drill holes completed during the 2026 drill campaign have intersected quartz-sulphide mineralization which generally corresponds to high-grade gold mineralization. 44 out of 98 planned drill holes have been completed with a total of 23,863 meters drilled in 2026.

The expanded Bonanza Zone has a strike of 1.8 km NW-SE and 1.8 km NE-SW. Mineralization in drill core from the expanded portions of the Bonanza is characterized by the presence of VG-NE as well as sphalerite and pyrrhotite in wide (up to 7 meter) intervals consisting of sheared quartz-sulphide breccia. Previously the Bonanza Zone contained 5 lodes up to 19 meters thick with a combined thickness of up to 27 meters and intercepts up to 8.35 g/t AuEq (8.31 g/t Au and 2.30 g/t Ag) over 23.00 meters (drill hole GD-24-280) and remains open for expansion.

The expanded Golden Gate Zone has a strike of 1.6 km E-W and 1.5 km N-S. Mineralization in drill core from the expanded portions of the Golden Gate Zone is characterized by sets of veins and veinlets hosted in andesitic volcanic rocks and mineralized with VG-NE, sphalerite, galena, pyrrhotite as well as trace pyrite and chalcopyrite. Previously the Golden Gate Zone contained 18 lodes up to 14 meters with a combined thickness of up to 49 meters and with intercepts up to 34.52 g/t AuEq (34.47 g/t Au and 3.96 g/t Ag) over 39.00 meters (drill hole GD-24-260) and remains open for expansion.

Visible Gold to the Naked Eye (VG-NE) has been intersected in multiple veins and shear zones from 26 out of 38 holes drilled in 2026 continuing to confirm the consistency of the mineralization within the Surebet system that remains wide open.
The fully funded 2026 drill program is underway and will include approximately 50,000 meters of systematic drilling designed to expand the known mineralization laterally and to depth (all mineralized lodes remain open for expansion and new discoveries), as well as test for the Motherlode Magmatic Gold Feeder Source, focused on defining a resource. Expansion drilling will focus on extending the footprint of the Bonanza Zone and Golden Gate Zone to the East and Northeast, as well as expanding the Surebet Zone to the West and testing other gold-rich mineralized lodes/veins that remain open. Additional drilling will be allocated to testing a number of lithological-structural features linked to magnetic anomalies strongly indicating the presence of a Motherlode causative magmatic intrusion gold feeder source. Directional drilling where multiple drill holes are extended from a single mother-hole is being employed on selected drill holes in order to cut down on drill time and money spending while also increasing accuracy of drill targeting.

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 Deposit TM 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 PhotonAssay TM 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 from these occurrences 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.
