Ridgeline Minerals Acquires High-Grade Oxide Gold Project, Further Consolidating Land Position at the Atlas Project, Nevada

Rhea-AI Summary

Ridgeline Minerals (RDGMF) has entered into an exploration earn-in option agreement to acquire a 100% interest in the Trench oxide gold project from EMX Royalty Corp's subsidiary. The project, comprising 31 mining claims over 2.2 square kilometers, is located near Carlin, Nevada, and will be consolidated into Ridgeline's Atlas project. Surface sampling has revealed high-grade gold up to 5.6 g/t Au in rock chips. To acquire full ownership, Ridgeline must issue 250,000 common shares, make payments totaling $650,000 over five years, and complete $500,000 in exploration expenditures. EMX will retain a 3.0% NSR royalty, which can be reduced to 2.0% through buyback options. The acquisition expands Atlas's mineralized footprint to over four kilometers of combined strike, with Ridgeline planning expanded exploration activities in H2 2025.

Positive

• Acquisition expands Atlas mineralized footprint to over 4km of combined strike
• High-grade gold samples up to 5.6 g/t Au found in surface sampling
• Strategic location near Carlin, Nevada with excellent infrastructure access
• Structured earn-in agreement allows gradual investment over 5 years

Negative

• Significant cash payments required ($650,000) over five years
• Additional $500,000 in exploration expenditures needed
• 3% NSR royalty burden (though reducible to 2%)
• Historical drilling results unknown, creating uncertainty

Vancouver, British Columbia--(Newsfile Corp. - May 29, 2025) - Ridgeline Minerals Corp. (TSXV: RDG) (OTCQB: RDGMF) (FSE: 0GC0) ("Ridgeline" or the "Company") is pleased to announce it has entered into an exploration earn-in option agreement to acquire a 100% interest in the Trench oxide gold project ("Trench or the "Project") from Bronco Creek Exploration, a wholly-owned subsidiary of EMX Royalty Corp. (TSXV: EMX) ("EMX"). The Project is host to an outcropping and historically underexplored Carlin-Type gold system that exhibits similar age host rocks and mineralization style to Ridgeline's adjoining Atlas project.

Trench is comprised of 31 Bureau of Land Management lode mining claims totaling 2.2 square kilometers. The Project is located approximately 30 kilometers southwest of the town of Carlin, Nevada, with excellent access to local infrastructure (Figure 1). The area was previously explored in the 1990's by several groups with surface trenching and limited drilling (results unknown). Anomalous, widespread gold mineralization and structurally controlled higher-grade gold grading up to 5.6 grams per tonne ("g/t") gold ("Au") is hosted within a sequence of prospective Ordovician to Pennsylvanian-Permian age rocks cut by a series of Tertiary dikes (Figure 2). These Tertiary dikes may represent a potential source to the Carlin-Type gold system and are a likely mineralizing control to the higher-grade rock chips taken to-date. As part of the agreement, the Company will inherit a surface geochemical database with technical highlights and exploration earn-in terms detailed below:

Mike Harp, Ridgeline's Vice President, Exploration, commented, "This is a great acquisition for Ridgeline as we further consolidate our Atlas oxide gold project in advance of a maiden drill program this spring. The Trench claims are contiguous with the greater Atlas project and exhibit high-grade gold at surface but has seen limited modern exploration. This consolidation expands the Atlas mineralized footprint to over four kilometers of combined strike and aligns with the Company's strategy of acquiring and systematically advancing underexplored projects in known gold districts."

Surface Sampling Highlights
34 reconnaissance rock chips were taken between the EMX and Ridgeline teams with grades up to 5.6 g/t Au (Figure 2).

• A series of high-grade rock chips ranging from 1.8 g/t Au to 5.6 g/t Au were taken from reclaimed trench locations that were originally built by operators in the 1990's (Figure 2 and Picture 1)
• Rock chip statistics : Min = 0.001 g/t Au, Med = 0.33 g/t Au, Max = 5.64 g/t Au

The current dataset at Trench is encouraging but limited in size. The Company plans to complete an expanded rock chip sampling and field mapping campaign in H2, 2025 to supplement the existing surface geochemical database.

Atlas Project
Atlas is a six square kilometer land package located in Eureka County, Nevada, approximately 30 kilometers southwest of the town of Carlin, NV. 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 towards mine development. The 100% owned Project is comprised of a total of eight square kilometers of highly prospective exploration ground that will benefit from the Ridgeline teams' systematic approach to discovery (view the Ridgeline Corporate Deck HERE).
