Caprock outlines 2026 operational highlights, 2027 work program at Destiny

Toronto, Ontario--(Newsfile Corp. - October 7, 2026) - Caprock Mining Corp. (CSE: CAPR) ("Caprock", or the "Company") is pleased to provide an overview of its operational highlights in fiscal 2026, and an update on its plans for the upcoming year 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, commented, "2026 was a year of milestones for Caprock - strengthening the Company's board of directors with the appointment of Jean-David Moore, completing our maiden drill program, intersecting high grade mineralization, and proving out our thesis on the Destiny gold project. We are now planning an extensive work program for this winter with the specific objective of expanding the Mineral Resource Estimate ("MRE") at Destiny, culminating in an updated MRE by the spring of 2027."

Highlights from Fiscal Year 2026

Highlights of 2-Phased Deep Drill Program:

• Drill hole DES-26-182 intersected 5.18 g/t Au over 1.5 meters;

• Drill hole DES-26-183 intersected 2.84 g/t Au over 23.2 metres, incl. 38.48 g/t Au over 1.6 meters;

• Drill hole DES-26-184 intersected 4.58 g/t Au over 2.5 meters and 2.68 g/t Au over 3.9 meters;

• Drill hole DES-26-184W1 intersected 8.32 g/t Au over 2.6 meters and 6.43 g/t Au over 1.8 meters.

Strengthening the Board:

Jean David Moore was appointed to Caprock's board on March 6, 2026. Mr. Moore has been a consultant and an advisor to several mineral exploration and development companies for over twenty years. He is a prominent investor in the junior mining space, and holds significant stakes in over 50 resource companies throughout Canada.

Mr. Moore serves currently on the boards of Bullion Gold Resources Corp., Dios Exploration Inc., Goldrea Resources Corp., Green Canada Uranium Corp., Opus One Gold Corp. and PTX Metals Inc. Previously, he served as a director of Vanstar Mining Resources Inc., which was acquired by Iamgold Corp. in February 2024, and Fokus Mining Corp., which was acquired by Gold Candle Ltd. (now Cadillac Mines Corp.) in April 2026.

Completion of Initial Shallow Drill Program:

The Company recently completed an initial shallow drill program consisting of three NQ-sized diamond drill holes totaling approximately 1,007m of drilling. All three holes were designed to fill a gap in drilling within the open-pit constrained MRE at Destiny. Assay results for these drill holes are pending and will be published in the coming weeks.

2027 Winter Drill Program:

Caprock has obtained all permits required for the Company's planned 2027 winter drilling program.

The Company will focus on the expansion of its MRE with at least one, and potentially a second, drill campaign. The first campaign will consist of 10 to 12 short drill holes aimed at expanding the MRE westward along strike. Management is also considering adding a second drill campaign, consisting of 10 to 12 short drill holes designed to expand the MRE eastward along strike.

Updated Mineral Resource Estimate:

The company plans to publish an updated MRE in the spring of 2027 following the completion of its winter drilling program.

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 (TSE:EQX) (Reference: Greenstone Gold Mines - Mining & Processing).
