Rockland Resources Announces Significant Gold Intercepts at Cole Gold Mines Property

Vancouver, British Columbia — June 25, 2026 — Leads & Copy — Rockland Resources Ltd. has announced additional drill results from its 100% owned Cole Gold Mines property in the Red Lake Mining District, Ontario. The findings include intercepts of 16.89 g/t Au over 4.00 meters in hole 2 of the recently completed 2026 winter drill program. Within this 4-meter interval, notable vein intercepts included 10.90 g/t over 1.00 m and 28.40 g/t over 2.00 m.

Drilling at the historic Cole Mineshaft has confirmed the gold-bearing quartz vein system that was explored between 1933 and 1937. The program also defined new gold-bearing veins situated below the deepest historic underground level, identified as the 530 Foot Level. One such intercept, in hole RR-26-03, returned 113.00 g/t Au over 0.50 m at a depth of 236.50 m, approximately 53 meters vertically below the deepest historic workings, at an estimated vertical depth of 214 meters.

Hole RR-26-02 yielded five intercepts with gold grades exceeding 8.00 g/t. These include grades of 28.30 g/t over 0.80 m, 13.20 g/t over 0.70 m, 11.40 g/t over 1.80 m, 32.60 g/t over 0.50 m, and 28.40 g/t over 2.00 m. A deep intercept in RR-26-02, located between 184.55 and 185.05 m, which showed significant visible gold, initially assayed 1.68 g/t Au by standard fire assay. A subsequent gravimetric-finish re-assay of a quarter-core split from this interval returned 279.00 g/t Au. This result is being reported transparently alongside its initial assay value.

The initial phase of drilling in early 2026 concentrated on vein systems previously identified within the historic Cole Mineshaft underground workings. Mineralization in this area is characterized as a stacked sequence of quartz veins hosted within quartz, and is concentrated at rheological boundaries between felsic, mafic, and ultramafic rock types. Visible gold was observed in multiple locations within the drill core. To account for the presence of coarse gold, the Company employed both standard fire assay and metallic screen analysis techniques. Metallic screen results are still pending for six samples from this set of holes.

“We are just now receiving the first Metallic Screen results and are encouraged that the first three holes drilled proximal to the Cole Mineshaft underground workings are showing high-grade stacked vein sets,” said Mike England, CEO of Rockland Resources. “We expect assays to continue streaming in now from the 300+ remaining samples and will announce accordingly, when received.”

Drill core samples were sent to Activation Laboratories Ltd. (Actlabs) at its Thunder Bay, Ontario facility for analysis. Standard analysis involved a 30 g aliquot fire assay with an atomic absorption finish. Samples containing visible gold or yielding 5 g/t Au or greater were also analyzed by metallic screen fire assay on a 1 kg aliquot, a 50 g aliquot fire assay with gravimetric finish, and a four-acid digest with ICP-MS finish. Rockland Resources' QA / QC program included certified reference materials, blanks, and field duplicates, all of which returned results within acceptable tolerances.

The technical and scientific disclosures in this news release have been reviewed and approved by Donald Hoy, M.Sc., P.Geo., a Qualified Person as defined by National Instrument 43-101 and a consultant to Rockland Resources.
