Rockland Resources Confirms Gold Mineralization Below Cole Mine Workings

Vancouver, British Columbia — June 9, 2026 — Leads & Copy —

Rockland Resources Ltd. has announced assay results from its initial winter drill program at the 100% owned Cole Gold Mines Property in Ontario's Red Lake Mining District. The drilling confirmed gold-bearing quartz vein systems extending below the historic Cole Mine workings, with intercepts including 113.00 g/t Au over 0.5 m. The initial three holes from the 19-hole program targeted the historic Cole Mineshaft and verified the gold-bearing quartz vein system that was mapped between 1933 and 1937. Mineralization presents as a series of stacked quartz veins, ranging from 30 cm to 1.8 m in width, with gold hosted in quartz and concentrated at rheological boundaries between felsic, mafic, and ultramafic rocks. These results demonstrate that the gold-bearing vein system continues at depth below the mine. Visible gold was observed in drill core from multiple holes. To address the potential for a “nugget effect” – where unevenly distributed coarse gold can lead to erratic grades in standard fire assays – the Company is conducting metallic screen analysis in conjunction with standard fire assay. This analysis processes a larger sample to yield a more reliable grade. Metallic screen results are pending for six samples, with additional results from the remainder of the program to be reported as they become available. "Our initial drilling has definitely confirmed high-grade gold mineralization at Cole," stated Mike England, CEO of Rockland. "Intercepts of 100 g/t gold are rare in our industry, making us even more excited about our upcoming program as the vein sets in the Cole Mineshaft area are located in close proximity to a large-scale structure identified in our airborne survey." Highlight results from the initial drilling include: * RR-26-01: 1.95 g/t Au over 2.55 m from 82.20 m, including 0.50 m at 3.84 g/t Au * RR-26-02 (multi-vein): 28.30 g/t Au over 0.80 m from 103.20 m; 11.40 g/t Au over 1.80 m from 109.00 m; 9.46 g/t Au over 1.80 m from 92.00 m, including 0.50 m at 32.60 g/t Au; 13.20 g/t Au over 0.70 m from 98.00 m; 8.99 g/t Au over 0.60 m from 74.75 m * RR-26-03: 113.00 g/t Au over 0.50 m from 236.50 m down hole, approximately 214 m vertical depth, or 53 m vertically below the deepest 1937 underground level; 4.59 g/t Au over 1.00 m from 146.00 m, including 0.50 m at 7.76 g/t Au All reported intercepts are down-hole lengths, with true widths pending further structural interpretation. Composite intercepts utilize a 0.5 g/t Au cutoff with a maximum of 2.0 m internal dilution. The winter drill program was the culmination of a multi-year effort including prospecting, mapping, sampling, and geophysical surveying. The program tested targets associated with the Cole Mineshaft, the GSL Zone on Greg Smith Lake, and surface mineralization on Pipestone Bay. Several holes were drilled to better understand geology in areas with significant overburden. An airborne magnetic geophysical survey identified several large-scale “D-2” structures that will be the focus of the upcoming Phase 2 drill program. Drill hole collar information was provided, with coordinates in NAD83 UTM Zone 15N. Samples were submitted to Activation Laboratories Ltd. (Actlabs) for analysis. Standard analysis is by fire assay on a 30 g aliquot with atomic absorption finish. Samples with visible gold or returning 5 g/t Au or greater undergo additional analysis, including metallic screen fire assay on a 1 kg aliquot. The Company's QA / QC program includes certified reference materials, blanks, and field duplicates.
