The Humdinger and Hunkadora occurrence is located in the low pass connecting Cultus and Next creeks, at an elevation of approximately 1450 metres. The recorded location is one of several occurrences along a strike length of 1 kilometre in an area primarily covered by overburden. It is along the trend of mineralization referred to in the Cultus Creek (MINFILE 082FSE056) occurrence and may be along strike of the Iva Fern (MINFILE 082FSE037) occurrence of similar character to the north.

Originally described as siliceous limestone, the host rocks are characterized in Assessment Report 10484 as silicified dolostone, part of one or two carbonate units occurring with schistose andesitic tuffs, siltstone and overlying phyllitic slate in the Irene Volcanic unit of the Horsethief Creek Group, part of the upper Proterozoic Windermere Supergroup. These units strike 340 degrees, parallel to the trend of the mineralization, with a steep westerly dip. The dolostone units are up to 600 metres thick, and locally contain as much as 10 per cent pyrite and chalcopyrite.

Mineralization is described as chalcopyrite disseminated through a siliceous and calcareous gangue, uniformly distributed over a width of approximately 2 metres; the lateral limits of the mineralization were not exposed. Pyrite, sphalerite and galena mineralization are also reported.

Old hand trenches are reported to have yielded up to 1.52 per cent copper, 23.9 grams per tonne silver and 2.0 grams per tonne gold over 7.2 metres (Property File - Yukon Revenue Mines Ltd. [1994-03-09]: No. 47 (1994) - Kootenay Property To Be Drill Tested). Grab samples from a sorted ore pile are reported to have yielded 1.4 grams per tonne gold and 3.21 per cent copper (Property File - MineQuest Exploration Associate Ltd. [1981-07-01]: Report on Cultus Creek Project Including Preliminary Exploration of Don and Next).

In 1927, a grab sample from the dump assayed 4.58 per cent copper, 82 grams per tonne silver and 2 grams per tonne gold, the balance being 60.6 percent silica and minor lime and alumina (Minister of Mines Annual Report 1927, page 326).

In 1929, a sample from a trench on the Hunkidora claim yielded 0.7 gram per tonne gold, 75.2 grams per tonne silver, 0.19 per cent copper, 1.1 per cent lead and 4.3 per cent zinc over 15 centimetres, while a dump sample from the adit on the Humbdinger claim assayed 1.70 per cent copper and 71.8 grams per tonne silver (Property File - C.C. Starr [1929-07-13]: Report on the Humdinger - Hunkidora Group).

In 1981, samples of mineralized float boulders yielded up to 1.2 per cent copper and 29 grams per tonne silver and 0.1 gram per tonne gold (Assessment Report 10484).

In 1987, two float samples yielded 1.05 and 1.77 per cent copper with 46.5 and 36.9 grams per tonne silver, respectively (Property File - New Spirit Resources [1988-02-09]: Prospectus Report on the Don & Next Mineral Claims).

The area has been historically explored in conjunction with the nearby Iva Fern occurrence since the early 1900’s and may represent the actual location of the original Cultus Creek group. A shallow tunnel and trench are reported from exploration work performed in the 1920’s.

In 1981, MineQuest Exploration Associates examined the area as the Don claims. Work included programs of soil sampling, prospecting, geophysical surveys and geological mapping. This work extended the zone of interest with induced polarization and geochemical anomalies. Significantly, this work suggested that a stratabound horizon containing the mineralization might extend from the Iva Fern showing 5 kilometres to the north to as far south as the Canada Belle (MINFILE 082FSE054) occurrence, roughly 30 kilometres.

In 1985 and 1986, Agincourt Explorations completed programs of prospecting, geological mapping, sampling and geophysical surveys. In 1987 and 1988, New Spirit Resources examined the area. In 1993 and 1994, Yukon Revenue Mines examined the property with programs of road work, trenching and diamond drilling.
