Big Ridge Gold Corp Commences IP Survey at the Hope Brook Gold Project

Executive Summary

• Big Ridge Gold Corp. has commenced a Wireless Alpha IP™ time domain survey at its Hope Brook Gold Project in Newfoundland & Labrador to delineate resistive high-sulfidation Au-Cu targets along strike from the Main and 240 Zones.
• The survey aims to map resistivity and chargeability anomalies down to 500 meters depth, with results expected by early July 2026 to guide precision drilling planned for mid-June.
• Environmental baseline studies are simultaneously underway to support permitting and mine planning, while the project currently holds a 1.2M oz Indicated and 231K oz Inferred gold resource.

Key Details

• Survey Commencement & Scope: Wireless Alpha IP™ time domain survey initiated by Simcoe Geoscience Limited, covering approximately 56 km across 35 lines (each 1.6 km long) with dipole spacing a = 100 m.
• Technical Objectives: Map resistivity and chargeability anomalies at depths up to 500 meters along strike from current mineralization to identify new resistive/high-sulfidation Au-Cu targets adjacent to strongly chargeable zones.
• Timeline: Survey completion targeted for early July 2026; drill rig mobilization scheduled for mid-June 2026.
• Data Processing & Interpretation: Program includes detailed data processing, full 2D and 3D modeling using inversion software, and a comprehensive interpretation report.
• Equipment Deployed: Alpha IP™ 2 Channel Time Domain Wireless Receiver Units, 1 Channel Current Recorder Time Domain Wireless Units, Walcer TX KW10 IP Transmitter, Honda MG12A generator, and stainless steel current/potential electrodes and wires.
• Previous Survey Context: 2023 IP data revealed two strong parallel chargeability anomalies extending over 3 km, correlating the Main and 240 Zones. The 240 Zone aligns with the downward projection of the southern chargeability feature, while the Copper Shaft Zone sits as a resistive island within a generally chargeable horizon.
• Drilling Integration: IP-derived targets will be integrated into current drill planning, which already encompasses over 30,000 meters of geotechnical, exploration, and infill drilling.
• Environmental & Permitting: Baseline programs launched for surface/groundwater, fish/habitat, wildlife, and avifauna to supplement previous studies and support Environmental Assessment, permitting, mine planning, and project engineering.
• Resource Estimate (Contextual): Indicated: 16,190,000 tonnes @ 2.32 g/t Au (1.2M oz); Inferred: 2,215,000 tonnes @ 3.25 g/t Au (231K oz). Cut-offs: 0.4 g/t (open pit) and 2.0 g/t (underground) at US$1,750/oz gold.
• Project Infrastructure: Operational 28-person camp, 1,100-meter airstrip, ice-free docking facility, and direct connection to the provincial electrical power grid via an on-site substation.

Notable Quotes

• Michael Bandrowski, President and CEO: "Its great to be back at Hope Brook and advancing this high-quality Au-Cu project. The IP survey will build on the 2011 and 2023 IP surveys to map anomalies down to 500 meters depth along strike from the Main and 240 Zones. With real-time data from the IP program, the Big Ridge team will be fully equipped to expand on known mineralization when the drill rig mobilizes in mid-June."
