Big Blue Porphyry Cu-Au Project Drill Program Commences

VANCOUVER - Ridgeline Minerals Corp. reported on the commencement of the diamond core drill program at the Big Blue porphyry copper (Cu) - gold (Au) project in Elko County, Nevada. The maiden drill program has been designed to test high-priority chargeability and resistivity anomalies located directly beneath the historically producing Delker Mine trend with the goal of intersecting the proposed porphyry source to the high-grade Cu-skarn observed at surface. The program will complete an initial 2-hole fence of up to 1,800 meters (m) starting with core hole BB25-001.

Mike Harp, Vice President, Exploration, said, "The first of two planned core holes is in progress and will be drilled beneath the historic Delker mine and directly across the porphyry dike swarm that is the interpreted source to the high-grade Cu-skarn at surface. Our recent IP survey has identified multiple highly prospective porphyry centers at Big Blue with the past producing Delker Mine trend being our shallowest and highest priority target. We will provide regular updates as the program progresses."

The initial program at Big Blue has been designed to test key structural and geophysical targets along the Delker Mine trend with the goal of intersecting high-grade Cu-skarn and/or porphyry Cu-Au style mineralization at depth.

BB25-001 will drill across the projected quartz feldspar porphyry (QFP) dike swarm and directly down-dip of the high-grade past producing Delker Mine. Hole will test both chargeability and resistivity anomalies identified in the Company's 2024 IP survey and has the potential to intersect both skarn and porphyry Cu style alteration and mineralization. Potential for a 2nd steeper angle hole beneath BB25-001 depending on visual results of the first hole.

BB25-002 will drill a near-vertical hole into the core of the 20-25 mV/V chargeability high that underpins the Delker Mine trend. This hole will target the conceptual porphyry source to the shallow high-grade Cu-skarn that was mined near-surface.
