Caprock Mining drills 38.48 g/t gold over 1.6 metres within a broader interval of 2.84 g/t gold over 23.2 metres at Destiny Project, Quebec

Caprock Mining Corp. [CSE: CAPR] reported high-grade assay results for drill hole DES-26-183 from the ongoing drill program at its flagship Destiny gold property, located near Val d’Or, Quebec.

Key Assay Highlights from Drill Hole DES-26-183: 38.48 g/t Au over 1.6 mteres, including within 2.84 g/t Au over 23.2 metres; 6.24 g/t Au over 1.0 metre and 2.78 g/t Au over 2.7 metres, included within 1.65 g/t Au over 5.3 metres; and 4.39 g/t Au over 0.5 metres.

Key Highlights from Historical Drilling at Depth: Drill Hole DES-01-60 intersected high-grade intervals of 26.6 g/t Au over 1.1 metres, 16.75 g/t Au over 0.7 metres, 7.5 g/t Au over 1.1 metres and 6.34 g/t Au over 0.7 metres.

Drill Hole DES-01-59 intersected high-grade intervals of 17.55 g/t Au over 0.5 mteres, 5.11 g/t Au over 0.6 metres, and 2.54 g/t Au over 1.1 metres.

Vishal Gupta, President & CEO, stated, “The high grades intersected in DES-26-183 not only validate our geological understanding of the property, but they also confirm our belief that Destiny hosts a very large gold-bearing system, and that we have barely scratched its surface despite the significant mineral resource published last year. Our technical team has identified a correlation between the presence of high-grade gold and the location of an intermediate intrusive dyke swarm. DES-26-183 was drilled to verify this correlation, and it ended up delivering our best intercept to date. We are now starting to formulate and fine-tune a targeting strategy to demonstrate the depth projection of the detailed structural model developed for Destiny by our senior operations consultant, Robert J. Tremblay, P.Geo. (retired), and unlock the vast gold potential of this Property.”

DES-26-183 is the first of four drill holes in our current drill campaign that is designed to continue testing Destiny’s high-grade mineralization potential at depth. The program is estimated to total 2,640 metres of drilling consisting of two pilot drill holes (DES-26-183 and DES-26-184) and two wedged drill holes (DES-26-183W1 and DES-26-184W1). The projection of the mineralized pierce point for DES-26-183 relative to drill holes DES-01-59 and DES-01-60, along with the four holes drilled in December 2025, is provided in Figure 1 below.

Our current drill program has successfully identified a complex swarm of intermediate intrusive dykes that appear to spatially control the distribution of high-grade gold within the Despinassy shear zone. Drill hole DES-26-183 intersected several significant mineralized zones, characterized by broad gold envelopes hosting high-grade intervals within them.

The high-grade intercept of 38.48 g/t Au over 1.6 metres was encountered at the contact between sheared basalts and an intermediate intrusive. This contact zone is characterized by a 15% quartz-carbonate stockwork with associated pyrite. However, our technical team has noted that the high-grade mineralization is not limited to just the contacts; it is also found directly within the intrusive dykes. Drill hole DES-26-183 intersected an intermediate intrusive from 708.00 to 715.35 metres which returned a high-grade intercept of 6.24 g/t Au over 1.0 metre, and is characterized by the presence of 90% laminated quartz veins with pyrite and pyrrhotite layers.

The results announced today confirm that Destiny remains open at depth, well below the floor of the conceptual open pit used in the March 2025 Mineral Resource Estimate (MRE). Our continued intersection of high-grade mineralization at depths exceeding 500 metres significantly strengthens the potential for underground resources to complement the near-surface MRE.

Destiny hosts an open pit-constrained MRE completed in March 2025 with the following gold inventory: Indicated Open Pit Resources with a cut-off grade of 0.30 g/t gold stand at 6,752,000 tonnes grading 0.91 g/t gold for contained god of 196,549 oz with Inferred Resources of 28,560,000 tonnes of 0.87 g/t gold for 794,886 oz.

The resource estimate was prepared by Todd McCracken, P.Geo, of BBA E&C Inc. in accordance with NI 43-101 – Standards.

Caprock Mining is a Canadian mineral exploration company focused on exploring precious metals in Quebec and Ontario. The company has an option to earn a 100% interest in the Destiny gold property that comprises 127 mineral claims and encompasses an area of 5,013 hectares located less than two hours’ drive from Val d’Or, Quebec. Destiny lies along a major deformation corridor in the Abitibi greenstone belt that includes the prolific Cadillac-Larder Lake, Destor-Porcupine and Casa Berardi fault zones which host numerous producing and development-stage gold deposits. The project overlies a 6.0 km long segment of the poorly explored Despinassy shear zone which is a splay off the regional Chicobi Fault. Destiny hosts a significant, open pit-constrained, NI 43-101 compliant mineral resource estimate published in March 2025.

Additionally, the company holds a 100% interest in three gold exploration properties in the historical Beardmore-Geraldton Gold Belt of Ontario, a belt that has produced over four million ounces of gold historically and contains the sizeable Greenstone gold project (formerly known as the Hardrock gold project) which is being brought to production by Equinox Gold.
