Star Metro - Excalibur IP Survey Results Confirm High Priority Copper Gold Drill Targets

The IP survey successfully identified a geophysical target that measures ~ 1 km x 2 km defined by coincident chargeability, resistivity, and magnetic responses. This geophysical target overlaps with the copper in soil anomalies collected in previous exploration campaigns and during the summer 2025 program. Together, these results suggest a strong potential for porphyry-style mineralization.

Henry Awmack, Excalibur Property co-vendor and member of Prospect Ridge's Technical Committee, states: "The IP survey has certainly helped define potential drill targets at Excalibur, identifying a very large volume of rock with moderate chargeability, hypothesized to represent chalcopyrite and pyrite. This drill target is partially flanked to the west by coincident high chargeability and low resistivity interpreted to be a pyrite halo so common to classic porphyry deposits and consistent with surface mapping. The moderate magnetic anomaly coincident with the moderate chargeability may be caused by magnetite alteration commonly found in the copper-bearing potassic core. When you take these positive geophysical features in combination with anomalous copper, gold and molybdenum soil samples, it is not hard to see why Prospect Ridge is excited to drill this target which has never seen previous drilling."

Prospect Ridge President and CEO, Len Brownlie, Ph.D, states: "It has taken six months, but we have used each well-planned exploration step to remove as much risk as possible ahead of the decision to drill Excalibur. My thanks go to Equity Exploration Consultants, an invaluable partner in this scientific enterprise, Simcoe Geosciences, our outstanding Technical Advisory Committee for their diligence and guidance, and to our shareholders who have made this possible. Over the next few weeks, we will confirm collar locations for multiple drill targets in a minimum 2,000 metre diamond drill program contemplated to begin as early as June, 2026, pending favourable weather conditions and receipt of a drill permit that was applied for on November 30, 2025."

IP Survey Results

Inverted sections were generated through six east-west lines covered by the IP survey, illustrate zones of elevated chargeability (greater than 20 mV/V) and low resistivity (less than 200 ohm-meters), characteristic of a pyrite-rich halo outboard of the target copper-bearing core of calc-alkaline porphyry deposits. The target area has moderate chargeability which is expected as the total sulphide content should be less than the pyrite halo. The coincident magnetic anomaly is interpreted to be caused by secondary magnetite commonly found in copper-bearing potassic core of porphyry copper deposits whereas high resistivity can be interpreted as the causative intrusion. The asymmetrical development of the system around the intrusive can be attributed to mapped, east to northeast dipping, faults that juxtapose Skeena Group sedimentary rocks against Kasalka Group volcanics in the east. An example of these features are shown in the cross section for line 6 including results from a previously completed magnetic survey, which was modelled using magnetic vector inversion (MVI) to highlight variations in magnetic susceptibility (Figure2, Figure 3, Figure 4).

About the Excalibur Property

On the Excalibur Property, suspected Bulkley and Babine intrusions cut Cretaceous stratified rocks, comprising Skeena Group clastic rocks to the west and Kasalka Group andesitic rocks to the east. A 50 to 500 metre wide by >1,600 metre long, east-west trending, Babine feldspar ± hornblende ± biotite porphyry dyke has been affected by a complex pattern of alteration, ranging from unaltered to propylitic and phyllic assemblages. Several outcrops of quartz-feldspar porphyry and granodiorite to the west are believed to be apophyses of the Bulkley stock exposed south of the Excalibur Property. No significant copper gold mineralization has been found in the main target area where there is less than ~2% outcrop.

Historic work has included mapping, soil sampling, IP, and ground magnetic surveys done by Canadian Superior in 1971-72¹. No significant work was conducted until 2019, when a former operator¹ cut five north-south trending 2500-2700 m long lines separated by 400 to 800 m in preparation for a planned IP survey which was not completed before the project was returned to the Vendors. One hundred and forty soil samples were then collected at 50 to 100 m intervals along the cut lines. Another former operator completed a 259-line kmairborne magnetic survey in 2021² and collected 207 soil samples in 2022². In 2025, Prospect Ridge collected another 50 soil samples along east-west lines and completed 26.3 line-km of IP surveys on six east-west trending lines.

A buried porphyry exploration target is supported by Prospect Ridge's 2025 IP survey, a magnetic vector inversion of the 2021 airborne magnetic survey² and the 2019¹,2022² and 2025² soil geochemistry results, in an area that otherwise lacks outcrops. Prospective features of the buried target area include anomalous Mo- and Cu-in-soil, moderate IP chargeability response, and moderately high magnetic response on the flanks of a chargeability high. The geophysical and geochemical signatures together could represent a mineralized potassic alteration zone surrounded by a pyrite halo, similar to the nearby Granisle and Bell Copper porphyry deposits of the Babine Plutonic Suite. The Property has never been drilled.

Funded and Positioned for Extensive 2026 Drilling

Subject to receipt of drill permits and favourable weather conditions, Prospect Ridge expects to finalize drill targets and commence a maiden drill program at the Excalibur Project beginning in June 2026.
