Very little information is available on the Lost Fiddle occurrence. Its location is taken as the centre of the Lost Fiddle claims (1-4), immediately west of Ottarasko Creek, 10 kilometres west of Tatlayoko Lake.

The showing consists of quartz veins, containing chalcopyrite and arsenopyrite, in rhyolite. The mineralization contains gold and silver as well as copper (Minister of Mines Annual Report 1967, 1968). Work completed by owner E.R. Flesher on the showing included 1 hand-trench, 9 metres long; 3 hand-trenches, 3 metres long each; and 44 metres of drilling in 7 diamond-drill holes.

The geological setting is difficult to define, as it is in a complex area of thrusts and steep faults involving Lower, Middle and Upper Cretaceous sedimentary and volcanic rocks, in the overlap assemblages near the northeastern margin of the Jurassic to Tertiary Coast Plutonic Complex (Geological Survey of Canada Open File 1163; Papers 68-33, 88-1E, 89-1E; Map 1713A; Geology 1991). The contacts between these units apparently follow the Ottarasko Creek Valley in the vicinity of the Lost Fiddle occurrence. Of the stratigraphic units involved, the Lower Cretaceous Taylor Creek Group contains rhyolitic volcanics, so it may be the most likely host for the occurrence. Other overlap formations in the area include the Lower Cretaceous Cloud Drifter Formation and the Upper Cretaceous Powell Creek Formation. Granodioritic stocks of the Tertiary to Paleocene Bendor suite intrude within a few kilometres west of the Lost Fiddle showings

Kingfisher Metals prospected the area of the Lost Fiddle historical showing in 2021 and outlined an area of blast trenching with quartz-sulfide breccias. Mineralization is defined by sulfide-cemented quartz breccias that contain primarily arsenopyrite in addition to chalcopyrite, sphalerite, and other unidentifiable dark grey sulfides. A total of 26 rock samples were taken for analysis. Gold values returned so far ranged from 1.1 grams per tonne gold to 42.8 grams per tonne gold; other sampling yielded values up to 1097 grams per tonne silver, 4.5 per cent copper, 0.95 per cent lead, 1.56 per cent bismuth, and 0.32 per cent cobalt (Press Release, Kingfisher Metals Corp., September 28, 2021). Backpack drilling was completed over several shallow holes in this area in addition to a tightly spaced soil survey. Drill and soil assays were still pending publication as of late March 2022).

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 most of the occurrences in the area since 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, Day Trip and CD North were visited. Geological mapping was completed along ridge and spur traverses in addition to select targets.
