Toronto, Ontario--(Newsfile Corp. - April 22, 2026) - Caprock Mining Corp. (CSE: CAPR) ("Caprock", or the "Company") is pleased to announce plans to commence a shallow drill program designed to expand the current open pit-constrained Mineral Resource Estimate ("MRE", or "Mineral Resource") westward at its flagship Destiny gold property ("Destiny", or the "Property", or the "Project"), located near Val d'Or, Quebec.

Caprock's President & CEO, Mr. Vishal Gupta, stated, "Our recently concluded deep drilling campaign at Destiny provided excellent corroboration of our structural understanding of the mineralized system. Assays have been received for five out of the eight deep holes drilled in total, and so far, we've had a consistently strong success rate, including high-grade assay results from drill hole DES-26-183 which returned 38.48 g/t Au over 1.6m, encompassed within 2.84 g/t Au over 23.2m. We must now take some time to reconcile the results and fine-tune our targeting strategy before building on this initial success with testing the deep-seated, high-grade potential at Destiny."

Mr. Gupta added, "While we wait for assays from the remaining three deep drill holes and take the time to conduct an in-depth analysis of our deep drilling campaign, we plan to focus our efforts on the expansion of the near-surface, open pit-constrained Mineral Resource at Destiny. Our technical team has identified the potential to materially expand the Mineral Resource westward by conducting a limited 10-hole drill program that was designed by our resource consultants at BBA E&C Inc. We plan to commence this resource expansion drill program immediately after receiving our drill permits, which are expected in the next few weeks."

Description of Resource Expansion Drill Program

The planned drill program has been designed to include 10 NQ-sized diamond drill holes totaling approximately 3,200m of drilling. The 10 holes will be drilled from four drill pads in total, and will test the extension of the mineralized domains at Destiny to the west of the current limits of the open-pit constrained Mineral Resource. Illustrations of the planned drill holes relative to previously drilled holes, the package of mineralized domains, and the conceptual open pit that constrains the current Mineral Resource at Destiny, are provided in Figures 1, 2, 3 and 4 below.

Mineral Resource Estimate at Destiny

Destiny hosts an open pit-constrained MRE completed in March 2025 with the following gold inventory:

1. CIM definition standards were followed for the resource estimate.
2. The 2025 resource model used ordinary kriging (OK) grade estimation within a three-dimensional block model with mineralized domains defined by wireframed solids.
3. Mineral resources are constrained within pit shells (OP).
4. An exchange rate of 1.35 is utilized in calculations ($CAD/$USD).
5. Open pit cut-off of 0.30 g/t Au milled is based on the cost/tonne ($CAD/t) milled for incremental mining, processing, and G&A based on the following:
   1. Long term metal prices of US$2,100/oz of gold;
   2. Metallurgical recoveries are based on metallurgical testing recovery of 94%;
   3. Average Bulk density (specific gravity) was determined for each lithology and/or mineralized domain within the deposit;
   4. Total ore-based cost of CAD$22.50/t;
   5. Processing costs of CAD$18.00/t and G&A costs of CAD$4.50/t milled;
   6. Dilution of 10%; and
   7. Pit Slope angle of 45 degrees.
6. Mineral Resources that are not mineral reserves do not have economic viability.
7. Numbers may not add due to rounding.

The resource estimate was prepared by Todd McCracken, P.Geo, of BBA E&C Inc. in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101").

About Caprock Mining Corp.

Caprock Mining Corp. 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 (Reference: Beardmore-Geraldton Gold Camp - Tashota Resources), and contains the sizeable Greenstone gold project (formerly known as the Hardrock gold project) which is being brought to production by Equinox Gold (Reference: Greenstone Gold Mines - Mining & Processing).
