DIOS INTERSECTS GOLD IN 2026 DRILLING PROGRAM AND EXTENDS HEBERTO'S FOOTPRINT FROM 600 METERS TO 900 METERS

Dios Exploration Inc. has released encouraging gold assay results from its Au33 project in James Bay, Quebec. The 2026 drill program expanded the Heberto gold-mineralized footprint, with nine holes completed for a total of 1,772 metres.

Highlights:

• 2026 drill program completed, including nine holes at Heberto for 1,772 metres;
• Drilling extends Heberto's footprint from 600 metres to 900 metres;
• New gold extension open to the north-northwest;
• Hole 863-26-55 returned 2.61 grams per tonne gold over 5.25 m, including 6.99 g/t Au over 1.50 m;
• Heberto gold zones seem very continuous in 3-D modelling;
• Historical results returned 4.79 g/t Au over 8.65 m within 2.13 g/t Au over 22.9 m in hole 2015-1 and 3.65 g/t Au over 13.00 m in hole 2016-19 within 1.21 g/t Au over 64 m;
• Heberto gold system remains open in strike extent: Bonano gold-in-soil anomalies and showing.

2026 Heberto drill highlights include (Table 1):

• 5.88 g/t Au over 1.60 m, including 13.00 g/t Au over 0.65 m, in hole 863-26-54;
• 2.61 g/t Au over 5.25 m, including 6.99 g/t Au over 1.50 m, in hole 863-26-55.

The drilling campaign extended gold mineralization up to 150 m northwest along strike and confirmed a similar mineralization style. Gold is hosted within metre-scale, north-northwest-trending shear zones shallow dipping west, associated with sericite-potassic feldspar-silica alteration and containing pyrite and magnetite.

Marie-Jose Girard, president and chief executive officer of Dios, commented: "The 2026 program has materially expanded the Heberto gold-mineralized footprint with encouraging gold assay results and a new gold extension open to the north-northwest. Heberto gold zones seem very continuous in 3-D modelling. In Heberto area, the Mitsumis batholith is characterized by several north-northwest and east-northeast structures; gold shear zones, quartz veins, stockwork and dioritic dikes are mainly related to north-northwest structures. Such structures are also observed near Bonano gold showing area and related gold-in-soil anomalies, not far north of Heberto, along the new open gold extension."

Qualified person and quality assurance/quality control

Technical information in this release was reviewed and approved by Marie-Jose Girard, PGeo (OGQ No. 00136), president of Dios (qualified person pursuant to National Instrument 43-101).

The 2026 drilling campaign and quality control program were planned and supervised by Jerome Augustin, PGeo (OGQ No. 2134). Core logging and sampling were completed by Laurentia Exploration in 2026: quality insurance and quality control include insertion of blank or standard samples every 10 samples on average, in addition to regular insertion of blanks, duplicates and standard samples accredited by Actlab Laboratories in Ancaster, Ont.

For all gold assays, gold values are estimated by fire assay with atomic absorption finish (method 1A2B-30). Silver was analyzed by aqua regia digestion and then ICP analysis (method 1E-Ag).
