Ridgeline Minerals Reports Remaining Assays from the Q4 2022 Drill Program at the Selena Project, Nevada

Vancouver, British Columbia--(Newsfile Corp. - March 6, 2023) - Ridgeline Minerals Corp. (TSXV: RDG) (OTCQB: RDGMF) (FSE: 0GC0) ("Ridgeline" or the "Company") is pleased to provide a summary of all assay results for the remaining six (6) unreported drill holes from the 2022 fall drill program at the Selena Project ("Selena" or "Project"), located in White Pine County, Nevada.

Highlight results from the Chinchilla Target include SE22-039A which returned 1.5 meters ("m") grading 581.0 grams per tonne ("g/t") silver ("Ag"), 0.2% zinc ("Zn"), and 2.0% Tungsten ("W") starting at 244 m downhole (Figure 1). Hole SE22-039A was an 11.7 m long wedge that was attempted off the original parent drill hole SE22-039, which was also lost in a fault zone in high-grade Ag-W mineralization at 279 m downhole (see January 24, 2023 press release HERE). The two intercepts now confirm over 30 m of vertical continuity within a structurally controlled zone of high-grade silver-tungsten mineralization hosted within Quartz-Feldspar Porphyry ("QFP") dikes. Mineralization hosted within QFP dikes is atypical of the Ag-Au-Pb-Zn Carbonate Replacement ("CRD") mineralization discovered at Selena to-date and may indicate a primary "feeder" fault has been intersected at the Chinchilla zone. Additional follow-up drilling is required in 2023 to confirm this theory.

The remaining five (5) core holes included a four-hole (4) maiden drill program at the Broken Egg oxide gold ("Au") target and a single (1) "scout" hole at the Juniper CRD target to test the down-dip extension of historical high-grade drill intercepts. Broken Egg returned a highlight intercept of 4.4 meters ("m") grading 0.68 grams per tonne ("g/t") gold ("Au") including 0.5m grading 2.66 g/t Au starting at 0.6m downhole in drill hole SE22-044 (Figure 1). A detailed summary of assay results is below.

Michael Harp, Ridgeline's Vice President, Exploration commented, "Over the past two years our systematic approach to exploration at Selena has yielded multiple grassroots discoveries that exhibit the potential for significant scale and grade. Our fall program at the Chinchilla zone returned the highest CRD grades ever drilled on the property and the addition of bonanza grade silver and tungsten intercepts in holes 39 and 39A adds a new high-grade target to be followed-up on this spring."

Mr. Harp continues, "The scout drill programs at Broken Egg and Juniper were part of our greater exploration strategy of assessing the potential of all priority exploration targets at Selena prior to commencing infill and definition drilling at the Chinchilla zone. Both targets intersected encouraging alteration and mineralization, with Broken Egg representing the distal expression of over 8 kilometers of alteration and mineralization that is zoning outwards from the Butte Valley Porphyry. Core drilling this year will focus on infilling the high-grade Chinchilla zone as well as step-out drilling towards the CRD target, where drilling to-date has defined over three kilometers of mineralized strike that is open in all directions. We eagerly anticipate the pending approval of an expanded exploration Plan of Operations permit this spring, which will allow us to aggressively explore this highly prospective mineralized corridor."

Chinchilla - CRD Target

• SE22-039A: 1.5 meters ("m") grading 581.00 g/t Ag, 0.19% Zn and 1.95% W starting 244 m downhole (Figure 2)
  • Poor core recoveries and void space noted throughout the hole prior to losing the wedge

Broken Egg - Oxide Au Target

• SE22-044: 4.4 m grading 0.68 g/t of oxide Au starting at 0.6 m below surface (Figure 1)
• Drill holes SE22-041 to SE22-043 tested multiple outcropping Au targets across three kilometers of strike and intersected extensive alteration structure and anomalous gold grades up to 0.40 g/t Au, including:
  • SE22-042: 1.9 m grading 0.19 g/t oxide Au starting at 83.7 m downhole

Juniper - CRD Target

• SE22-040: 6.5 m grading 0.27 g/t Au starting at 43.6 m downhole (Figure 3)
  • And: 0.7 m grading 34.44 g/t Ag, 0.25% lead ("Pb"), 0.10% zinc ("Zn") and 0.47 g/t Au starting at 178.4 m downhole (Figure 3)
  • CRD mineralization in SE22-040 is hosted within a fault-controlled breccia zone on the footwall side of the Aurym fault (interpreted as a primary feeder fault to the Juniper target). Future drilling would focus on the hangingwall side of the Aurym fault (Figure 3)

Early-Stage Exploration - Revival CRD Target

• Drilling at Revival was conducted in Q4, 2022 by Ridgeline geologists using the Company's backpack drill rig, which can drill core to depths of 15-20 m vertical depth (Figure 1)
• Highlight intercept in SEBP-005 returned 2.7m grading 34.57 g/t Ag, 0.17% Pb, 1.18% Zn and 1.00 g/t Au starting at surface
• Additional permitting is required at Revival in 2023 prior to initiating a maiden drill campaign

Selena Project
Selena is located in White Pine County, Nevada, approximately 64 kilometers ("km") north of the town of Ely, NV. The project shares a property boundary with the Butte Valley project, a US $33M earn-in agreement between Freeport-McMoRan and Falcon Butte Minerals. The 100% owned project is comprised of 39 square kms of highly prospective exploration ground including Ridgeline's shallow-oxide Ag-Au-Pb-Zn Chinchilla discovery. Subsequent drilling has continued to highlight the potential for high-grade CRD type mineralization between Chinchilla and the Butte Valley Cu-Au-Ag porphyry located directly west of the property.
