The Ridgeline showing is located 34 kilometres south-southeast of Kleena-Kleene and 25 kilometres west of the north end of Tatlayoko Lake.

The Ridgeline showing occurs near a thrust fault boundary where Late Triassic to Cretaceous metamorphic rocks of the Eastern Waddington thrust belt imbricate zone, consisting largely of schist, gneiss and migmatitic rocks, (having a sedimentary and volcanic protolith), are thrust over an Upper Triassic package of limestone, marble and calcareous sedimentary rock. This limestone package is itself thrust north over an Upper Triassic package of marine sedimentary and volcanic rocks consisting of tuffaceous and lapilli tuffs. A granodioritic pluton of the Late Cretaceous to Paleocene Bendor suite intrudes the across the thrust faults and into the imbricate and overlap strata to the south and northwest of the Ridgeline showing.

A number of talus fines and rock samples were taken along the ridgeline over a 5.5-kilometre length. Only a few assays were published thus far with one of the rock samples grading 1.14 copper (Press Release, Kingfisher Metals Corp., September 28, 2021 (Figure 7). A float sample (S3690966) contained 0.11 gram per tonne gold and 4.5 per cent copper (Assessment Report 39734). This sample was collected from a trench completed as a soil anomaly follow-up in the northern half of the Blackhorn ridge soil traverse. This sample was noted to be float with quartz-carbonate veining and massive chalcopyrite, with angularity suggesting it is proximal to outcrop. The Blackhorn Mountain prospect (092N 019) occurs about 7 kilometres to the south along the same ridgeline and within the same thrust fault imbricate package that hosts the Ridgeline showing.

In 2021, a total of 214 rock samples and 2604 soil and talus fine samples were collected on the Goldrange property of Kinfisher Metals Corp which contained of the mineral occurrences in the area since staking in 2020. Backpack drilling of shallow holes was completed at the Lori (092N 047), Langara (092N 036), Lost Fiddle (092N 018), and Lotus (092N 062) zones. Other new showings such as Razorback (092N 097), Day Trip (092N 096, and CD North (092N 098) were discovered. Geological mapping was completed along ridge and spur traverses in addition to select targets.
