Ridgeline Minerals Corp. announced the staking of the Big Blue Project, a high-grade porphyry copper ("Cu") - gold ("Au") - silver ("Ag") exploration prospect in Elko County, Nevada. 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 project. A total of 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.

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. 2023 Exploration Plans: First Quarter 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 exploration permit to allow for up to 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. Big Blue Project: Big Blue is located in Elko County, Nevada, approximately 75 kilometers southeast of the city of Elko, NV. The project shares a property boundary with the Medicine Springs Project, a Carbonate Replacement type exploration project operated by Reyna Silver.

Outcropping garnet skarn with high- grade Cu ± Au-Ag rock chip samples collected by Ridgeline occurs on the Project on two outcropping buttes surrounded by post-mineral gravels covering a roughly 5 km target area zoning towards Medicine Springs. The primary target at Big Blue is porphyry-skarn Cu ± Au-Ag mineralization, which may be the source of CRD mineralization at Medicine Springs - analogous to the Butte Valley porphyry Cu-Au system inferred to be a source of CRD mineralization at the Company's Selena project. The 100% owned Project is comprised of a total of 29 square kilometers of highly prospective exploration ground that has seen limited exploration since the early 1900's and will benefit from the Ridgeline teams systematic approach to discovery.
