The Caribou (Strebe) gold occurrence is located at an elevation of approximately 2060 metres on the south eastern spur of Hailstorm Peak, approximately 15.5 kilometres east of the Lower Arrow Lake community of Burton.

The area is underlain by highly deformed Triassic and older (?) volcanic and sedimentary rocks of and younger aplite and feldspar porphyry dikes, and granitic intrusions. The volcanic rocks are the oldest units and are tentatively assigned to the Slocan or Kaslo Group, while the younger sedimentary rocks are correlated with the Slocan Group.

Locally, skarn zones in an intensely brecciated and calc-silicate– altered sediment within the hanging wall of a syenite porphyry sill hosts native gold and sulphides. Sulphide mineralization consists of variable amounts of pyrrhotite, pyrite, sphalerite and galena with traces of chalcopyrite, tetrahedrite and scheelite occurring as fine disseminations to coarse-grained aggregates. Alteration minerals include quartz, plagioclase, tremolite, actinolite, clinozoisite, garnet, biotite and microcline. Native gold occurs within the skarn assemblages as 25 micron disseminates to 1 centimetre flakes with in and along the margins of the quart-calc-silicate segregations and is associated with pyrrhotite, pyrite, sphalerite and galena mineralization. Free gold has also been found in the soil, in a black graphitic manganese fault and in a marble.

The main zone averages 3.3 metres thick, trends 020 degrees and dips 30 to 50 degrees to the west. It has been traced along strike and depth for approximately 200 metres each. Numerous faults are present. It is suspected that Bonanza type gold deposits will be found where they intersect the limestone or marble. A structural geology study indicates that the bearing of the limestone strikes 005 degrees, with a dip of 40 degrees west.

In 1984, surface sampling yielded up to 5.35 grams per tonne gold over 2 metres (Assessment Report 18638). In 1987, channel sampling yielded 15.4 grams per tonne gold across 12 metres, including 34.2 grams per tonne gold over 5.4 metres (Assessment Report 18638).

In 1987, seven of eight diamond drill holes yielded a weighted average of 5.5 grams per tonne gold over an average thickness of 5.4 metres with values up to 11.3 grams per tonne gold over 10 metres (Assessment Report 18638). The following year, diamond drilling yielded values up to 43.4 grams per tonne gold over 3.8 metres (Assessment Report 18638).

In 1997, trench sampling yielded up to 46.21 grams per tonne gold over 0.66 metre from trench TR97-05, 33.41 grams per tonne gold over 2 metres from trench TR97-12; while trench TR97-04 yielded 6.78 grams per tonne gold over 4.5 metres including 17.43 grams per tonne gold over 3.3 metres (Assessment Report 25456). Diamond drilling, performed at the same time, yielded up to 6.03 grams per tonne gold over 4.0 metres, including 11.46 grams per tonne gold over 0.5 metre in drill hole 97-03 (Assessment Report 25456).

In 2008, sampling of skarn mineralization exposed in the drift assayed 24.4 grams per tonne gold over 4.0 metres (Assessment Report 31345).

Drill-indicated reserves were reported, in 1988, as 116,120 tonnes grading 8.57 grams per tonne gold with an additional drill-inferred reserve of 156,040 tonnes grading 8.57 grams per tonne gold (Assessment Report 18638).

In 1985 and 1986, a 4.54 tonnes bulk sample of hand-cobbled, high- grade skarn ore is reported to have yielded an average of approximately 171 grams per tonne gold (Assessment Report 18638).

Three claims, the Hailstorm, Londonerry and Golden Rodd No. 2 (Lots 5875-5877 respectively) were held from 1899 or earlier by J. D. Jamieson and T. Matthews. The claims were Crown-granted in 1903. Exploration work was done in trenches and a short adit was driven on the east slope of the mountain. Early in 1929, the Consolidated Mining and Smelting Company of Canada Limited optioned the Crown-grants and four located claims. A crosscut adit at 2130 metres elevation on the west slope of the mountain was driven for 275 metres during the year. Further crosscutting and some raising was done in 1930. This work failed to locate values similar to the main outcrop, although most of the crosscutting was from a raise directly under the outcrop; the option was abandoned.

The area was acquired by Roxwell Gold Mines Ltd. in approximately 1981. In 1982, Esperanza Explorations, in conjunction with Suncoast Petroleum and Roxwell Gold Mines, completed a program of geological mapping and geochemical sampling on the area as the London claims. The following year, Grey Wolf Mountain Explorations completed a program of rock and soil sampling and geological mapping on the area immediately east, as the Caribou claims. During 1980 through 1987, the area was prospected by Alex Strebchuck. In 1987 and 1988, Esperanza Explorations completed programs of road building, surface sampling and 24 diamond drill holes, totalling 2776 metres, on the area as the Strebe property. In 1997, Baron Gold Corp. completed a program of trench sampling and six drill holes totalling 779.1 metres on the area.

In 2006, Genex Mining Company completed 117 metres of underground development from an exploration adit at 2037 metres elevation. The adit failed to intersect the gold- bearing skarn zone. During 2007 through 2010, Kuskanax Mountain Properties completed programs of rock sampling, drilled three percussion drill holes, totalling 60.9 metres, and extended the adit for 29 metres along with a 21 metre drift, a 7 metre crosscut and a 17 metre raise. In 2014, the area was prospected and sampled by S. Strebchuk.
