Juggernaut Exploration Confirms Big Mac Zone Extent, Expands Drill Program

Vancouver, British Columbia — August 19, 2026 — Leads & Copy — Juggernaut Exploration Ltd. has reported initial observations from its maiden drill program, confirming the Big Mac Zone's extent to a depth of 500 meters and a strike of 450 meters. Broad intervals, up to 30.11 meters, of quartz-sulphide mineralization have been intersected on the 100% controlled Big One property in British Columbia's Golden Triangle.

The Big Mac Zone remains open for expansion both laterally and at depth. Multiple drill holes encountered substantial intervals of quartz-sulphide veins and shears exhibiting textures visually similar to surface samples that assayed up to 114.60 g/t AuEq, with continuous channel cuts yielding up to 4.89 g/t AuEq over 5.21 meters. The drill program has been significantly expanded and is ongoing.

The Big Mac Zone has a confirmed surface strike of 450 meters with a down-dip extent confirmed in drill core of 500 meters. Multiple drill holes intersected broad quartz-sulphide veins and shears up to 30.11 meters wide, containing chalcopyrite, galena, and sphalerite. These are similar to high-grade gold-bearing samples collected on the surface.

Drill hole BO-26-14 intersected the Big Mac Zone in a 30.11-meter interval from 461.40 to 491.51 meters, comprising two shear zones separated by silicified diorite with disseminated pyrite and sphalerite. The first shear zone, from 461.40 to 464.86 meters, featured strongly sheared diorite with veins containing up to 2% disseminated pyrite. The second shear zone showed foliated and silicified diorite with trace sulphides. Assays for this hole are pending.

Drill hole BO-26-02 intersected the Big Mac Zone in a 11.22-meter interval from 117.48 to 128.70 meters, characterized by veins and veinlets up to 1 meter wide with up to 2% pyrite and trace chalcopyrite, enveloped by strong quartz-sericite alteration. Assays are pending.

Drill hole BO-26-18 intercepted the Big Mac Zone in a 10.04-meter interval from 374.51 to 384.55 meters, containing foliated diorite with disseminated pyrite and veins with up to 1% pyrite, alongside pervasive quartz-sericite alteration. Assays are pending.

Drill hole BO-26-05 intersected the Big Mac Zone in a 9.12-meter interval from 130.02 to 139.14 meters, consisting of sheared diorite with veins and veinlets containing up to 1% pyrite and galena, enveloped by quartz-sericite alteration. Assays are pending.

Drill hole BO-26-07 intercepted the Big Mac Zone in a 6.57-meter interval from 153.66 to 160.23 meters, containing disseminated pyrite within the shear zone and in veins up to 20 cm wide with strong quartz-sericite alteration. Assays are pending.

Drill hole BO-26-04 intersected the Big Mac Zone in a 5.26-meter interval from 122.81 to 128.07 meters, characterized by veins and veinlets up to 0.5 meters wide with up to 2% pyrite and trace galena, enveloped by strong quartz-sericite alteration. Assays are pending.

Surface exploration at the Big Mac Vein has returned high-grade results, including grab samples assaying up to 114.60 g/t AuEq and a continuous channel cut yielding 4.89 g/t AuEq over 5.21 meters. Drilling and geological mapping confirm the vein and its hosting shear structure measure up to 30 meters wide, with a surface exposure exceeding 450 meters and a vertical relief of up to 360 meters. The system remains open along strike and at depth.

Microscopic inspection identified coarse-grained, free-milling gold up to 150 microns in size within the vein, indicating favorable metallurgical characteristics. Pervasive propylitic alteration outside the veins and shear zones has been confirmed in all drill holes that intercepted the Big Mac vein, suggesting proximity to a buried porphyry core.

The 2026 drill program has been expanded by approximately 30%, from 10,000 meters to 13,000 meters, due to the observed mineralization and intercept lengths. Manuele (Lele) Lazzarotto, President and COO of Juggernaut Exploration, stated that the inaugural drill program has exceeded expectations, confirming the Big Mac Zone's extent and visual similarities to high-grade surface samples. He noted the company's significant expansion of the drill program to approximately 13,000 meters to further explore the discovery at depth and along strike.

The expanded program will utilize two drill rigs to test the largest and most extensive veins within the 22 km² Eldorado zone. Surface samples from this zone have assayed up to 263.70 g/t AuEq, with channel cuts yielding up to 4.89 g/t AuEq over 5.21 meters. Juggernaut reports over 400 mineralized veins, up to 10 meters wide, hosted in shear zones up to 50 meters wide, exposed on surface for over 1 kilometer with over 1 kilometer of vertical relief, all remaining open.

Drilling, sampling, and mapping confirm that gold mineralization at Big One is linked to a Jurassic to Cretaceous transpressional system and associated intrusive sources, coinciding with the magmatic events that formed nearby multi-million-ounce porphyry deposits. Mineralized veins and shear zones were emplaced through brittle-ductile deformation, forming a major structural corridor at Big One. The system shows widespread porphyry-style propylitic alteration, which aids in vectoring towards the mineralization source.

The Eldorado System covers 22 km², where grab samples have assayed up to 263.70 g/t AuEq. Juggernaut reports 400 mineralized veins, up to 10 meters wide, hosted in shear zones up to 50 meters wide, exposed on surface for 500 meters with 1 km of vertical relief, remaining open. The Gold Swarm Discovery, a 3 km area, features 100 gold-rich polymetallic veins exposed on surface for 200 meters, up to 4.5 meters wide with up to 700 meters of vertical relief, with grab samples assaying up to 231.81 g/t AuEq.

Within the Eldorado System, 41% of samples collected in 2024 and 2025 assayed 1 g/t AuEq or higher. Within the Gold Swarm Zone, 65% of samples collected in the same period assayed 1 g/t AuEq or higher. Gold samples up to 256.60 g/t, silver samples up to 2810 g/t, and copper samples up to 14.40% were collected on Big One.

A petrographic study by the Colorado School of Mines confirmed that gold occurs as relatively pure, free-milling gold up to 150 microns in size. Fluid inclusions indicate high-pressure conditions, suggesting a magmatic origin. The polymetallic veins, alteration signature, and geochemical anomalies strongly indicate the presence of a large, buried gold, silver, copper-rich porphyry feeder source.

Detailed mapping confirms mineralization at Eldorado and Gold Swarm is linked to a Jurassic to Cretaceous transpressional system and intrusive sources, coeval with magmatic events that formed nearby porphyry deposits. The district-scale system exhibits widespread porphyry-style propylitic alteration, which will help identify the mineralization source. Mineralized veins and shear zones were emplaced through brittle-ductile deformation, forming a major structural corridor at Big One with northeast, east, and northwest trends, consistent with the orientations and geochemical signatures of gold-mineralized veins along the 15 km Highway of Gold corridor, indicating a single district-scale gold system.

The overall geochemistry of the gold-rich veins is clean, with no occurrence of deleterious elements such as mercury or arsenic. The 5-year drill permit, valid until March 31, 2031, will allow the company to define the extent of mineralization and understand the geometry of the system in preparation for a future resource estimate.

The Big One property is situated in a region known for hosting precious metal and porphyry deposits, including nearby systems at Galore Creek, the KSM gold reserve, and the Shaft Creek copper project. The property geology is favorable, confirmed by extensive areas of propylitic alteration, untested geophysical anomalies, strong geochemistry, key structures, porphyry-style mineralization, and high-grade polymetallic veins.

The Big One property is accessible year-round via helicopter from the Glenora/Telegraph Creek Road and the Galore Creek Road. The Canadian government has committed $20 million to extend/improve the Galore Creek Road to within 15 km of the property. The property is located 2 km west of the Scud River airstrip.

The Big One property exploration qualifies for the Critical Mineral Exploration Tax Credit (CMETC).
