Highlights

• Three-hole shallow drill program completed at Destiny.
• Established continuity of mineralization in an area where there was a gap in previous drilling.
• Results expected to increase confidence in current MRE and expand overall Mineral Resource.
• Resource expansion drilling planned this winter, followed by updated MRE in spring of 2027.
• Drill permits required to complete this winter’s planned drilling have been obtained.

Caprock Mining Corp. (CSE: CAPR) is pleased to announce assay results for the recently concluded three-hole shallow drill program designed to establish continuity of mineralization across a gap in previous drilling within the current open pit-constrained Mineral Resource Estimate at its flagship Destiny gold property, located less than two hours’ drive from Val-d’Or, Quebec.

Caprock’s President & CEO, Mr. Vishal Gupta, stated, “Destiny’s overall mineralized package is comprised of a series of multiple stacked gold-bearing domains that collectively extend along an east-west strike and dip to the north at a 65 degrees angle. The recently concluded short 3-hole drill campaign was designed to fill a gap in drilling within the south-southwest portion of the resource zone at Destiny. Each of the three holes drilled in this campaign achieved its objective of intersecting the gold-bearing domains that constitute the mineralized package and establish continuity of mineralization in an area where there was little or no previous drilling. These results should not only help increase the confidence in the current MRE at Destiny, but also expand the overall Mineral Resource in its next iteration, currently planned for the spring of 2027.”

Mr. Gupta added, “Management is planning an extensive resource expansion program this winter with at least one, and potentially a second, drill campaign. The first campaign is expected to consist of 10-12 short drill holes aimed at expanding the MRE westward along strike. This drill program has already been designed for us by our resource consultants at BBA E&C Inc. A second drill campaign is currently being contemplated with the objective of drilling an additional 10-12 short drill holes designed to expand the MRE eastward along strike. All drill permits required to complete this winter’s planned drilling have been obtained.”

Description of the 3-Hole Drill Program

The drill program announced today consisted of three NQ-sized diamond drill holes totaling approximately 1,007m of drilling. All three holes were drilled from the same drill pad and were designed to fill a gap in drilling within the open-pit constrained Mineral Resource at Destiny. Table 2 summarizes the attributes of each of the three drill holes.

Figures 1 and 2 below illustrate the intersection of multiple gold-bearing domains that collectively form the overall mineralized package at Destiny by each of today’s three drill holes. Assay results from these three holes have helped establish continuity of mineralization along the south-southwest portion of the resource zone at Destiny. In general, mineralization is strongly shear-controlled within intermediate intrusives and basalts. High-grade intervals correlate with pervasive brown biotite-ankerite-sericite and chlorite alteration, folded and boudinaged blue quartz veins, and up to 30% fine pyrite stringers.

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 demonstrated 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.

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 Property 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 (TSX: EQX) (Reference: Greenstone Gold Mines – Mining & Processing).

Sample Preparation & QA/QC Protocols

The drilling program was managed by Explo-Logik of Val-d’Or, Québec. Drill core was split in half, with one half submitted to AGAT Laboratories at Val-d’Or for analysis. Gold was analyzed by fire assay (50 g) with atomic absorption finish, while base metals were analyzed by four-acid digestion with ICP-OES finish. Samples with gold grades greater than 10 g/t were reprocessed using metallic screening with a 106 µm cut-off. The processed material was split and analyzed by fire assay with ICP-OES finish to extinction. A separate split was prepared to independently analyze mineralized intervals with a target grade greater than 1.00% Cu-Zn using a Na₂O₂ fusion with ICP-OES or ICP-MS finish. Sample preparation duplicates, certified reference standards, and blanks were inserted into the sample stream.

The Company maintains no corporate, financial or non-arms-length relationship with AGAT Laboratories, ensuring completely independent and unbiased analytical results.
