Star Metro - Prospect Ridge Completes Knauss Creek and Holy Grail Exploration; Launches Castle and Excalibur Copper-Gold Porphyry Programs

VANCOUVER, BC / ACCESS Newswire / August 14, 2025 / Prospect Ridge Resources Corp. (the "Company" or "Prospect Ridge") (CSE:PRR)(OTCQB:PRRSF)(FRA:OED) is pleased to announce the successful completion of field programs at its Knauss Creek and Holy Grail projects, and the commencement of exploration activities at its newly acquired Castle and Excalibur copper-gold porphyry projects in north-central British Columbia (B.C.). The Company also confirms receipt of a $200,000 B.C. Mineral Exploration Tax Credit (METC), further strengthening its current treasury of $2.3 million.

Completion of Knauss Creek and Holy Grail Programs

At the Company's 100%-owned Knauss Creek and Holy Grail projects, located just north of Terrace, B.C., crews from Equity Exploration Consultants Inc. have completed a four-week program of prospecting, mapping, and rock sampling across 17 high-priority exploration targets. An additional three targets will be assessed within the next ten days while field crews complete preparations for other programs. (Figure 1).[ML1]

The program, based at Prospect Ridge's fully equipped Terrace camp, utilized the Company's fleet of trucks and ATVs, along with helicopter support from Quantum Helicopters Ltd. A total of 61 rock samples were collected and sent for assay, with results expected in the coming weeks[ML2]. Detailed geological mapping will be integrated with assay data to highlight potential drill targets across the fully drill-permitted[RV3] combined land package of 625.5 km².

President & CEO Len Brownlie commented:

"After spending a day in the field with the Equity Exploration team at Holy Grail, I was extremely impressed by their mapping and prospecting work in challenging alpine terrain and under adverse weather conditions. Based on what I observed, I am confident the team has thoroughly reviewed all high-priority targets on both Holy Grail and Knauss Creek, and we look forward to receiving the assay results and Equity's final report."

Excalibur Copper-Gold Porphyry Project

The Excalibur project (formerly "Jacobite") covers 27.7 km² in the Skeena Natural Resource Region of central B.C. It is road-accessible, close to infrastructure and power, and lies in an area of active mining and exploration, including Quartz Mountain Resources Ltd.'s Jake and Maestro projects[RV4].

A one-week mapping and prospecting program was completed on July 29, with 15 rock samples submitted for assay. Fieldwork identified chalcopyrite mineralization outcropping within a copper-in-soil anomaly and mapped several newly identified diorite porphyry intrusions. Some of these porphyries exhibited feldspar replacement by epidote, which may represent propylitic-style alteration characteristic of peripheral zones in porphyry systems.

The Company has secured a permit exemption for its planned 30 line-km Induced Polarization (IP) survey over key copper anomalies. Contractor selection is underway, and the survey is expected to be completed in September 2025.

President & CEO Len Brownlie added:

"We are extremely excited to continue our exploration efforts over the next two months on the newly acquired Excalibur and Castle projects. With the recent $200,000 METC from the B.C. government and a strong treasury, Prospect Ridge is well positioned to advance these promising assets rapidly and strategically."

Castle Copper-Gold Porphyry Project

The Castle project, covering 29.14 km² in the Toodoggone gold-copper district, is located approximately 40 km northeast of Thesis Gold Inc.'s Ranch project.

A 325 line-km airborne magnetic and radiometric survey will be conducted by Pioneer Exploration Consultants Ltd. within the next four weeks, followed by an 8 line-km IP survey conducted by SJ Geophysics Ltd. focused on the north and west Castle gossan slopes. The Company has also received a permit exemption for the IP survey. Concurrently, field crews will carry out prospecting and mapping over both the Castle and Abbey gossans.

Next Steps

The objective of the current programs at all four projects is to define multiple high-priority drill targets in preparation for a minimum 2,000-metre diamond drilling campaign on each property, targeted for summer 2026 and pending receipt of all necessary permits [RV5] .
