Caprock Provides Update on Drilling and Announces Expansion of Drill Program at Its Destiny Gold Project

Toronto, December 17, 2025 - Caprock Mining Corp. (CSE: CAPR) ("Caprock" or the "Company") is pleased to provide an update on its ongoing drilling activities, and announces an expansion of its drill program to test deep-seated, high-grade mineralization at its flagship Destiny gold property ("Destiny" or the "Project" or the "Property") located near Val d'Or, Quebec.

Caprock's President & CEO, Mr. Vishal Gupta, stated, "We're very excited to report that all three drill holes that have been completed to-date during our current drill program have intersected significant zones of silica flooding with sulphide mineralization and intense shearing at approximately the same depths downhole as were expected based on our geological model for Destiny. Our technical team believes that this combination of characteristics is highly conducive to gold mineralization, based on our review of previously drilled holes on the Property. A fourth hole is currently being drilled and is expected to be completed before we break for Christmas. 2026 is promising to be a defining year for Caprock as we anticipate publishing assay results from the current drill program starting in January."

Expansion of Drill Program & Additional Details

The intensity of drill core characteristics that are suitable for gold mineralization, the broad thicknesses of the potentially mineralized zones, and the validation of our technical team's geological model for Destiny, has prompted management to expand the current drill program to continue into January and February of 2026, from the originally planned four drill holes totaling 1,700-2,000 metres to an eventual eight to nine drill holes totaling 4,500-5,000 metres.

All eight to nine drill holes in the current campaign are designed to target the (1) vertical gap of 200-250 metres from the floor of the conceptual open pit at the DAC deposit that was used for the generation of the current Mineral Resource Estimate (MRE) at Destiny, to the high-grade zone intersected at depth by previously drilled holes DES-01-60 and DES-01-59, and (2) the lateral gap of over 200 metres between DES-01-60 and DES-01-59. These two historical drill holes produced intercepts with grades as high as 26.6 g/t Au and 17.5 g/t Au, respectively at approximately 550 metres depth below surface. The three holes drilled to-date in our current campaign have all intersected potentially the same mineralized horizon as DES-01-60 and DES-01-59.

Historical drill intercepts mentioned in this press release have been referenced from the "NI 43-101 Technical Report And Resource Estimate Of The DAC Deposit, Destiny Property, Quebec" prepared for Alto Ventures Ltd. and Pacific Northwest Capital Corp. by Todd McCracken, P.Geo. of Wardrop a Tetra Tech Company, with an effective date of March 1, 2011.

Details of the MRE at Destiny

The open pit-constrained MRE at Destiny contains the following gold inventory:

Mineral Resource Statement Notes:

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/ton ($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.
8. 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.

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).
