About this update from Ridgeline Minerals Corp

Vancouver, British Columbia--(Newsfile Corp. - February 12, 2026) - Ridgeline Minerals Corp. (TSXV: RDG) (OTCQB: RDGMF) (FSE: 0GC0) ("Ridgeline" or the "Company") is pleased to announce a Mineral Exploration Target outlining the silver-gold-lead-zinc exploration potential at the Company's outcropping Chinchilla Oxide Ag-Au-Pb-Zn deposit at the Selena project ("Selena" or "the Project"), Nevada. The Company has completed preliminary 3D modelling at the Chinchilla Oxide deposit that supports an exploration target of 38.3 - 58.0 million tonnes ("MT") of mineralized material grading between 39.8 - 52.0 grams per tonne ("g/t") Ag, 0.12 - 0.15 g/t Au, 0.42% - 0.55% Pb and 0.40% - 0.51% Zn (Figure 1). The quantity and grade of the exploration target are conceptual in nature and there has not been sufficient exploration to define a mineral resource. It is uncertain whether further exploration will result in the exploration target being delineated as a mineral resource.

Announcing a mineral exploration target helps to further highlight this exciting opportunity and better frame the upside potential across multiple mineralized zones at the Selena project. Chinchilla Oxide remains open along strike and down-dip towards our recent Chinchilla Sulfide discovery with potential to expand the exploration target and upgrade to a maiden mineral resource estimate with additional drilling." Mr. Peters continues, "The Selena project exhibits over four kilometers of proven mineralized strike between the outcropping Chinchilla Oxide zone and our recent high-grade CRD discovery at Chinchilla Sulfide, which was made in collaboration with our partners at South32. Our strategy in 2026 will be to continue drill testing the Chinchilla Sulfide discovery to better understand the potential scale and ...
