Vancouver, British Columbia - Ridgeline Minerals Corp. (TSXV: RDG) (OTCQB: RDGMF) (FSE: 0GC0) ('Ridgeline' or the 'Company') is pleased to announce the staking of the Big Blue Project, ('Big Blue' or the 'Project') a high-grade porphyry copper ('Cu') - gold ('Au') - silver ('Ag') exploration prospect in Elko County, Nevada (Figure 1). The Company acquired Big Blue via low-cost staking of 361 lode claims totaling 7,255 acres (29 square kilometers). The Project is 100% owned by the Company and retains no underlying lease payments, work commitments or royalty obligations.

The Big Blue Project includes the past producing Delker Mine, which produced 94,434 pounds of copper at an average grade of 6.2% Cu between 1916-1917 1 and shares its southern boundary with Reyna Silver's Medicine Springs Ag-Pb-Zn Carbonate Replacement ('CRD') project (Figure 2). A total of nineteen (19) confirmation rock chip samples were collected by Ridgeline in late 2022 between the Delker Mine workings and Skarn Hill adit, returning an average grade of 1.8% oxide Cu including a highlight sample of 6.4% Cu, 0.2 grams per tonne ('g/t') Au, and 53.8 g/t Ag at Skarn Hill (Picture 1 & Figure 2). The Project has seen limited exploration over the past 100+ years and represents an opportunity to expand the known high-grade Cu-Au-Ag Skarn mineralization as well as discover new deposit types including Cu-Au Porphyry and Ag-Au-Pb-Zn CRD style mineralization at depth and along strike towards the Medicine Springs project.

Chad Peters, Ridgeline's President & CEO, commented, 'This is the first project staked and generated by our team in the Company's history and consolidates a core land position within a historic but significantly underexplored porphyry district in Nevada. Our team's exploration thesis for Big Blue is analogous to the Butte Valley porphyry Cu-Au system located roughly 60 km to the south, which is inferred to be the source of CRD mineralization at our Selena project. Big Blue exhibits similar potential to host new, high-grade porphyry-skarn copper discoveries as well as CRD mineralization on-strike of the Delker Mine towards the Medicine Springs project, a known CRD discovery being explored by Reyna Silver. The Project is royalty free with no underlying work commitments and will be advanced alongside our growing CRD discovery at Selena.'

Skarn Hill: 6.44% Cu, 0.16 g/t Au, 53.75 g/t Ag (Picture 1 & Figure 2)

Delker Mine: 4.88% Cu, 0.10 g/t Au, below detection limit ('BDL') Ag (Picture 1)

Delker test pit: 6.31% Cu, 0.09 g/t Au, 4.21 g/t Ag

A total of 19 rock chip samples were collected during initial reconnaissance work ranging from 0.01-6.4% Cu, 0.009-0.2 g/t Au and BDL-53.8 g/t Ag (avg. 1.83% Cu, 0.05 g/t Au, 3.16 g/t Ag)

Q1 2023 will focus on acquiring any available historical data for the Project to support an initial 3D geologic model. The team will follow up with mapping and prospecting in the spring as well as select Ridgeline operated backpack drill holes in the vicinity of the Delker Mine to chase shallow high-grade Cu skarn mineralization. The Company will also begin permitting a Bureau of Land Management administered Notice of Intent ('NOI') exploration permit to allow for up to five (5) acres of surface disturbance, which will be allocated to road and pad building to support a maiden drill program in the second half of the year.

Ridgeline is a discovery focused gold-silver explorer with a proven management team and a 192 km-2 exploration portfolio across six projects in Nevada and Idaho, USA. More information about Ridgeline can be found at www.RidgelineMinerals.com
