Grizzly Extends Gold-Silver Mineralization at Midway Mine Area and Identifies New Gold Occurrence at Sappho Critical Minerals Target Area Greenwood, BC

Edmonton, Alberta--(Newsfile Corp. - September 8, 2026) - Grizzly Discoveries Inc. (TSXV: GZD) (FSE: G6H) (OTCQB: GZDIF) ("Grizzly" or the "Company") is pleased to announce that preliminary results for a Phase 2 sampling program conducted in June 2026 to follow up trenching conducted at the Midway Precious Metals and Critical Minerals Target and Induced Polarization ("IP") chargeability results at the Sappho Critical Minerals Target (Figure 1). Highlights Significant Gold and Silver from chip samples in a trench extending the Main Midway Mine trend with up to 22.8 grams per tonne (g/t or ppm) gold (Au) and up to 1,120 g/t silver (Ag) (Figures 2 and 3; Table 1). Additional samples in trenches immediately east of the Main Midway Mine with up to 1.7 g/t Au and to the southwest with up to 2.7 g/t Au. Drilling is set to test these anomalous samples and the historical Midway Mine this fall, 2026 (Figures 2 and 3; Table 1). The Midway area is a window into the Paleozoic - Triassic rocks through the Toroda Graben and Tertiary volcanics that fill the graben. Follow up sampling in the vicinity of the Sappho Chargeability Anomaly identified in early to mid 2026 (See Company News Release dated July 6, 2026) has yielded 4.73 g/t Au from quartz float at the headwaters of Norwegian Creek but coincident with the northeast edge of the anomaly (Figure 4). Host rocks in the area are mapped as late Paleozoic to Early Triassic metasedimentary rocks including carbonates and calcareous shales. A number of dykes, stocks and large intrusions are mapped in the area and likely range from Jurassic to Cretaceous to Eocene in age. The Geological Setting is the East Fault Contact of the Toroda Graben with numerous pyroxenite-monzonite-diorite (older - Jurassic) and younger quartz-feldspar porphyry (QFP)-diorite (Tertiary) intrusions into the sedimentary package and the overlying younger intermediate-mafic volcanics. The East and West Faults of the Toroda Graben likely played a role in controlling the Au-Ag mineralization for the Buckhorn Skarn and Mine to the southwest and the Cu-Au-Ag mineralization for the Motherlode/Greyhound skarns in the Greenwood area (Figure 1). Permitting of drill locations to test the Sappho Chargeability Anomaly is underway. The Company is planning to complete an initial drill test this fall, 2026. The Company is currently in the process of permitting additional drillhole pads to complete drill testing of a number of the chargeability targets during a fall drilling program at the Motherlode Critical Minerals Target area along with potentially the Sappho Critical Minerals Target area and the Midway Precious Metals - Critical Minerals Target area. Further IP work, geological mapping and surface sampling centered on several of the targets is planned prior to the commencement of drilling. Figure 1: Midway and Sappho Target Areas 2026.

New samples have yielded significant gold and silver and the Grizzly team is excited to see what drilling might show us at both the historical Midway Mine and the Sappho Chargeability Target - we will continue to refine these targets to the drill ready stage for drilling in the next couple of months and look forward to identifying and presenting some new discoveries for the shareholders of Grizzly."

Additional groundwork including ground geophysical surveys are being planned and will comprise IP, magnetics and Loupe electromagnetics (EM) for the Sappho, the Midway and Motherlode areas (Figure 1). Additional drilling is planned from October to December. Results as they become available from the 2026 work will be released as they are received.

Three (3) of the 7 selective rock grab samples from the Midway Mine yielded from 1,360 g/t Ag (39.7 opt) up to 2,140 g/t Ag (62.4 opt) (see Company news release dated October 17, 2022). Two new showings identified in 2023 near the historical Midway Mine including up to 5.64 g/t Au (0.165 opt) from a showing 400 m to the north of Midway and up to 4.19 g/t Au (0.122 opt) from a grab sample collected about 375 m to the west of the Midway Mine. At least 6 new areas with anomalous gold (> 100 ppb), copper (>200 ppm) and silver in soils have been identified at Midway in work conducted between 2022 and 2024. The Midway area is being targeted for copper-gold skarn and epithermal gold-silver. All highly anomalous samples are from outcrop and characterized by the presence of abundant pyrite, arsenopyrite with visible galena and sphalerite in a siliceous chalcedonic host. The mineralization is hosted in polymetallic veins that display the presence of Pb, Zn, Cu, arsenic (As) and antimony (Sb) and are likely epithermal in nature. A selective rock grab sample from outcrop 200 m west of the main Midway Mine yielded 15.85 g/t Au (0.462 opt) and 1,530 g/t Ag (44.6 opt), illustrating that there is potential for additional high-grade mineralization in the area.

All core and rock samples were prepared using ALS procedure PREP-31A (dry, crush to 70% passing 2mm, riffle split off 250g, pulverize split to better than 85% passing 75 microns) and analyzed by method PGM-ICP27 (30g fire assay with ICP finish for Au, Pt and Pd) and ME-ICP61a (0.5g, four acid digestion and ICP-AES/MS analysis) for multi-elements. Any samples containing >10g/t Au are reanalyzed using method FAS-415 (30g Fire Assay with gravimetric finish). Samples containing >100 ppm Ag and/or >1% Cu, Pb, & Zn are reanalyzed using method ICF-6 (0.2g, 4-acid digest and ore grade ICP-AES analysis). Rock samples were analyzed using Au-ICP21 (30g fire assay with ICP-AES finish) and multi-elements using ME-ICP41 (0.5g, aqua regia digestion and ICP-AES analysis). The reported work has been completed using industry standard procedures, including a quality assurance/quality control ("QA/QC") program consisting of the insertion of certified standards, blanks and duplicates into the sample stream by APEX personnel. The ALS geochemical laboratory data was provided directly to APEX and the QP and has been verified by the QP.
