VANCOUVER, BC / ACCESS Newswire / July 7, 2026 / Prospect Ridge Resources Corp. (the "Company" or "Prospect Ridge") (CSE:PRR,OTC:PRRSF)(OTCQB:PRRSF)(FRA:OED) is excited to announce it has secured a multi-year area based ("MYAB") drilling permit, valid for five years, and all other ancillary permits for its 100% owned Excalibur copper-gold porphyry project1. Excalibur is a road-accessible, 28 km2 tenure in British Columbia's prolific Babine porphyry belt - strategically positioned near the former Huckleberry, Bell, and Granisle mines - and hosts a compelling, never-drilled 1 km x 2 km geophysical and geochemical target (Figure 1)2.
Why Excalibur matters
Large, untested target: A strong, coincident chargeability, magnetic and multi-element soil anomaly highlights potential for a sizeable buried porphyry-style system
Classic porphyry signatures: Recent induced polarization ("IP") survey work shows moderate chargeability in the target zone flanked by high chargeability/low resistivity interpreted as a pyrite halo - exactly the hallmarks of copper‑bearing calc‑alkaline porphyries. A coincident moderate magnetic high is interpreted as magnetite-rich potassic alteration in a potential copper-bearing core (Figure 2).
Strategic location: Proximal to known Babine belt deposits, Excalibur's signatures mirror features seen at nearby past-producing porphyry deposits and recently discovered mineralized porphyries such as Duke (Amarc Resources Ltd. and Boliden Mineral Canada Ltd.) and NAK (American Eagle Gold Corp.; TECK Resources Ltd and South32)3,4.
Management comments
"IP chargeability, magnetic response and anomalous copper, gold and molybdenum in soils, and limited peripheral outcrop have defined a large volume of altered, sulphide-bearing rock that has never been drilled," said Henry Awmack, member of Prospect Ridge's Technical Committee. "Taken together, the geophysics and geochemistry make this a high-priority target for a new discovery."
"Our team have been preparing to drill test this exciting new porphyry target in an established mining district since fieldwork in late 2025 more clearly defined the target," added Prospect Ridge President & CEO Len Brownlie, Ph.D. "This program is designed to discover a new Babine-style copper‑gold porphyry system - a potentially transformational event for the Company."
Program and next steps
Drill program: Targeting multiple drill collars for an initial ~3,000 metre program, subject to drill contract finalization. Commencement anticipated in July 2026.
Technical basis: 2025 IP survey, 2021 airborne magnetic inversion (MVI) modelling, and multi-element soil geochemistry all support a buried porphyry target despite limited peripheral outcrop.
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. Copper, gold, and molybdenum mineralization is indicated by anomalous soil values over the overburden-covered main targets.

Historical work includes mapping, soil sampling, and geophysical surveys (1971-72, 2019-2022); Prospect Ridge completed additional soil sampling and a six-line IP survey in 2025. The targets are undrilled.
A buried porphyry exploration target is supported by these geophysical, geochemical and geological evidence. Prospective features of the target area include anomalous Copper, Molybdenum, and Gold in soils, IP chargeability, and high magnetic response flanked by the chargeability high. The geophysical and geochemical signatures together are interpreted to represent a mineralized potassic alteration zone surrounded by a pyrite halo, similar to the nearby Granisle and Bell Copper porphyry copper deposits of the Babine Plutonic Suite. The Property has never been drilled.
Funded and Positioned for Extensive 2026 Drilling
Prospect Ridge is funded and positioned to mobilize for the 2026 drill program, with further updates and assay results to follow as the program progresses. Prospect Ridge is also aggressively advancing two other projects in its portfolio in 2026 with drilling also planned for the Camelot Project.

The zone of coincident moderate chargeability and magnetism is interpreted to be a copper-bearing drill target, with high chargeability rocks to the west interpreted as the pyritic rich phyllic halo. The lack of pyrite halo to the east, i.e., the asymmetry of the system, can be attributed to a fault mapped between Skeena sedimentary rocks and Kasalka volcanics in the east.
