Prospect Ridge Awarded Excalibur Drill Permit - Maiden Drill Program Planned For July 2026

About this update from Prospect Ridge Resources Corp.

VANCOUVER, BC / ACCESS Newswire / July 7, 2026 / Prospect Ridge Resources Corp. (the "Company" or "Prospect Ridge") (CSE:PRR)(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 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."
