RIDGELINE MINERALS INTERSECTS UP TO 1.8 G/T OXIDE GOLD IN MAIDEN DRILL PROGRAM AT THE ATLAS PROJECT, NEVADA

Ridgeline Minerals Corp. has provided assay results for the maiden two-hole drill program at the company's Atlas project, Nevada. Atlas is an early stage Carlin-type oxide gold prospect and is 100 per cent owned by the company with no underlying work commitments or royalties. Details on the drill program are highlighted below.

Mike Harp, Ridgeline's vice-president, exploration, commented: "We are pleased that our maiden drill program confirmed that our Atlas project exhibits both the scale and grade potential that's required to host a significant gold deposit. The first two drill holes at Atlas were completed in the northernmost section of a greater than four-kilometre gold trend. With a limited budget this year, our focus was testing the favourable Pennsylvanian to Permian age carbonate host rock section to confirm whether those host rocks showed evidence of a Carlin-type gold system."

Mr. Harp continues: "Both holes returned thick intercepts of anomalous oxide gold and Carlin-type alteration, with hole AT25-001 exhibiting a stronger gold vector to the south than AT25-002. Hole AT25-001 intersected 298 metres of continuous Carlin-type alteration and mineralization with elevated pathfinder elements, anomalous gold and up to 1.8 g/t gold in individual samples."

Mr. Harp concludes: "Mineralization at Atlas appears to be hosted within the same thick section of Pennsylvanian to Permian age host rocks that host Orla Mining's nearby Dark Star deposit. Our team interprets the first two holes as having intersected a low-grade gold and trace element halo that is typically associated with the outer margins of Carlin-type gold deposits. We will continue to focus on land consolidation and additional field work throughout the remainder of the 2025 field season with the goal of a phase II drill program in 2026 to follow up on these results."

Drill program highlights

The maiden program completed two core holes totalling 551 metres (m) in the northern section of the Atlas land package. Drilling targeted favourable Pennsylvanian to Permian (Penn-Perm) age debris-flow conglomerates, limestones and siltstone host rocks along a roughly one-kilometre (km) trend of elevated gold-in-soils and rock chips grading up to 7.7 grams per tonne Au (gold).

AT25-001 drilled to the east and down dip of gold-bearing and partially eroded Penn-Perm host rocks and intersected a highlight intercept of:

• 0.2 metre grading 1.80 grams per tonne (g/t) gold (Au) and 2.10 g/t silver (Ag) within 8.5 m grading 0.20 g/t Au and 0.52 g/t Ag starting at a true vertical depth (TVD) of 80 metres:
  • Additional results include multiple 1.0- to 5.0-metre intercepts throughout the hole ranging from 0.1 to 0.5 g/t Au and 0.1 to 5.0 g/t Ag starting at 30 metres TVD.
• Drilling also intersected high-grade silver intercepts within clay altered fault zones that returned 1.5 m grading 75.1 g/t Ag and 0.5 m grading 52.5 g/t Ag.
• The hole returned 297.9 m grading 0.01 g/t Au, 0.41 g/t Ag and bottomed in anomalous Au mineralization.

AT25-002 was collared approximately 700 m north of AT25-001 and drilled to the west toward the same gold-bearing and partially eroded Penn-Perm host rocks and intersected a highlight intercept of:

• 5.9 m grading 0.20 g/t Au and 2.43 g/t Ag starting at 124 m TVD;
• 2.6 m grading 0.25 g/t Au and 2.59 g/t Ag within 9.8 m grading 0.15 g/t Au and 2.20 g/t Ag starting at 182 m TVD:
  • 1.4 m grading 31.6 g/t Ag within a clay altered fault zone.
• The top of AT25-001 intersected 106 m of andesite (volcanic rocks) with the remainder of the hole drilling a partial section of Penn-Perm rocks that returned 147.6 m grading 0.01 g/t Au and 0.41 g/t Ag.

Geologic interpretation

Both holes intersected a thicker than anticipated section of Penn-Perm debris-flow conglomerate host rocks (150 to 300 m), which exhibited weak to strong Carlin-type alteration and oxide mineralization throughout with both holes bottoming in oxide mineralization.

• Anomalous gold-silver and Carlin-type trace element pathfinders were observed throughout both drill holes with the highest values (up to 1.8 g/t Au and 75.1 g/t Ag) associated with strongly altered and mineralized Penn-Perm carbonate host rocks.
• Compared to AT25-001, hole AT25-002 exhibited similar zones of widespread silicification, decalcification and oxidation. However, AT25-002 returned weaker Au values overall.
• Results from these two holes indicate a potential vector to the south where the intersection of a northeast- and northwest-trending fault corridor coincides with a kilometre-scale gold in soils and rock chip anomaly.

QA/QC (quality assurance/quality control) procedures

Samples are submitted to American Assay Laboratories (AAL) of Sparks, Nev., which is a certified and accredited laboratory, independent of the company. Independent check samples are sent to Paragon Geochemical Labs (PAL) of Sparks, Nev. Samples are prepared using industry-standard prep methods and analysed using FA-PB30-ICP (Au; 30 g fire assay) and ICP-5AM48 (48-element suite; 0.5-gram five-acid digestion/ICP-MS) methods at AAL and analyzed using a photon assay (Au-Ag, 500 g) at Paragon. AAL and Paragon also undertake their own internal coarse and pulp duplicate analysis to ensure proper sample preparation and equipment calibration. Ridgeline's QA/QC program includes regular insertion of CRM standards, duplicates and blanks into the sample stream with a stringent review of all results completed by the company's qualified person, Michael T. Harp, vice-president, exploration.

Atlas project

Atlas is located in Eureka county, Nevada, approximately 30 kilometres southwest of the town of Carlin, Nev. The property exhibits classic Carlin-type alteration and gold mineralization within outcropping Pennsylvanian to Permian age carbonate to siliciclastic host rocks. The primary target at Atlas is a bulk tonnage, oxide, Carlin-type gold system, which is analogous to the nearby Dark Star gold deposit (part of the greater Railroad mining district), which is currently owned by Orla Mining and advancing toward mine development. The 100-per-cent-owned project is comprised of a total of six square kilometres of highly prospective exploration ground that has never been drill tested and will benefit from the Ridgeline teams' systematic approach to discovery.
