Prospect Ridge Resources Corp. Advances 2026 Exploration Program with Discovery Drill Programs At Excalibur and Camelot Copper-Gold Porphyry Projects Prospect Ridge Resources Corp. is advancing a catalyst-rich 2026 exploration season with discovery drill programs planned at both the Excalibur and Camelot copper-gold porphyry projects in British Columbia and target development work planned at the Castle copper-gold porphyry project in the Toodoggone. Excalibur: High-priority magnetic and chargeability targets defined by a ground geophysical survey in 2025 and supported by highly anomalous copper and gold values in soil are planned to be tested by an inaugural 3,000-meter discovery-focused drill program in summer 2026. A multi-year area-based (“MYAB”) drilling permit is expected imminently. Camelot: Drilling results from 2025 provide vectors to potential mineralized porphyry centers and drone-based LiDAR and magnetic surveys are underway to support target refinement for a planned 2,000-meter follow-up drill program in Second Quarter/Third Quarter 2026. A multi-year area-based (“MYAB”) drill permitting is in process. Castle: Machine learning-based satellite hyperspectral alteration mapping nearing completion to support a grid rock sampling program designed to vector towards mineralized alkalic centers. The sampling will be completed in parallel with a 3D IP survey to define high-priority drill targets. A multi-year area-based (“MYAB”) drilling permit is in process now to support 2027 drill testing. 2026 Exploration Plans Excalibur – Large-Scale Babine Copper-Gold Porphyry Target The road-accessible, 28 km2 Excalibur tenure is located in BC’s prolific Babine porphyry belt near the past-producing Huckleberry, Bell, and Granisle mines. The property hosts a compelling 1 km x 2 km chargeability and magnetic target that is coincident with a large copper-gold soil anomaly. Prospect Ridge has completed all required archaeological, wildlife, and ancillary permitting work in support of a planned 3,000-meter discovery drill program and anticipates final MYAB permit approval in the coming weeks. Camelot – Cariboo Discovery Follow-up Program In 2025, Prospect Ridge acquired a 100% interest in the 26 km² Camelot tenure, located near Imperial Metals’ Mount Polley Mine and surrounded by the Vizsla Copper Woodjam property in the Cariboo Mining District, BC. The initial exploration program intersected what could be the edge of a new copper-gold mineralized porphyry system, with follow-up modelling defining vectors to higher temperature alteration and mineralization. CAM25-009 from the initial drill campaign returned anomalous copper and gold over a 157-metre core length grading 0.1 g/t gold and 0.1% copper starting at the top of bedrock below the overburden cover. The alteration mineralogy and IP geophysics are consistent with an interpretation that drilling intersected the margin of a porphyry system. Importantly, all 10 drill holes returned anomalous copper and gold values, supporting the scale of the system across the property. Au-to-Cu ratios, determined from core assays, show a 1:1 positive correlation, between gold (g/t) and copper (%) grades, and confirm that gold may represent a meaningful by-product of copper mineralization. In May, the Company initiated a property-wide LiDAR and magnetic drone survey expected to enhance drill target refinement ahead of a follow-up drill program later in Second Quarter/Third Quarter 2026. In June a focussed core review now in progress is expected to provide additional detailed targeting insights. Recent announcements by Imperial Metals Corporation (Mount Polley), Viszla Copper Corp. (Woodjam Project) and Inomin Mines Inc./Sumitomo Metal Mining Canada Ltd. (Beaver/Lynx) of exploration drilling campaigns on projects surrounding Camelot point to increasing exploration momentum across the district and highlight growing recognition of the region's discovery potential. Castle – Emerging Toodoggone Porphyry Target At the 29 km² Castle tenure in the highly prospective Toodoggone mining camp, Prospect Ridge continues to advance a large alkalic porphyry target beneath an intensely altered and leached (lithocap) zone associated with coincident magnetic, chargeability, and copper-gold in soil anomalies. Current and planned work includes: Machine learning-based satellite hyperspectral alteration mapping by ALS Goldspot that is nearing completion and will be used to map alteration minerals associated with copper-gold porphyry mineralization and define geologic domains in advance of fieldwork. A grid rock sampling, spectroscopy, and petrography program designed to define the footprints of and vectors towards mineralized alkalic porphyry centers. A distributed array IP survey to better define identified chargeable zones related to sulphide mineralization and assist in definition of high-quality drill targets. The Company has applied for a MYAB drill permit in preparation for a 2027 drill program on the highest priority targets. Subject to permit approvals and weather conditions, Prospect Ridge expects to begin drilling at Excalibur during early summer 2026, followed by additional exploration activities across its broader portfolio and a follow-up Camelot drill campaign in Second Quarter/Third Quarter. With active exploration across three flagship projects, multiple high-priority targets, and strong technical momentum, Prospect Ridge is positioned for a transformational year in 2026.
