The KRL claim group is located on a ridge to the east of Mclymont Creek and 5.2 kilometres north of the Iskut River junction.

First explored in 1988 by Kestrel Resources Limited prospecting in 1989 led to the discovery of visible gold mineralization in south east- trending quartz veins on the KRL 3 mineral claim. A program of geological mapping, soil sampling, ground magnetometer, electromagnetometer mapping, hand trenching, and rock chip sampling was conducted later that year on the claim. In 1990, continued mapping led to the discovery of additional mineralized quartz veins and extended the area of interest by 500 metres. A 1500 metre drill program was completed the same year.

Regionally, the claims are underlain by andesitic tuffs, argillaceous phyllites, and minor intercalated cherts and siltstones of Permian to Devonian age. Intermediate coast crystalline rocks of Mesozoic age cover a large portion of the property.

Locally, steeply dipping, southeast trending tensional fractures filled with quartz and carrying visible gold occur near the western boundary of the KRL 3 mineral claim. Eleven veins, with surface dimensions of up to 1 metre by more than 60 metres, occur within a large north easterly trending stratified structure that may represent the northwest limb of an anticline. Transcurrent, dextral movement along a series of north easterly trending faults has off-set the veins by up to 20 metres (Property File: Clifton Star Resources Inc., (1990/06/01): Statement of Material Facts No.29/90).

Mineralization consists of quartz veins carrying free gold and minor amounts of pyrite, chalcopyrite, pyrrhotite, and arsenopyrite. Sulphides occur as finely disseminated grains or masses. Malachite and azurite stains are common as oxidation products. Gold occurs as small flakes or as irregular, elongated masses or as wire-like, rounded particles up to 2 millimetres in size (Property File: Clifton Star Resources Inc., (1990/06/01): Statement of Material Facts No.29/90).

In 1989, channel samples from hand trench T-9 returned values up to 248.1 grams per tonne gold (Property File: Clifton Star Resources Inc., (1990/06/01): Statement of Material Facts No.29/90). The next year, drilling on hole KRL 90-11 intersected 0.30 metres grading 38.0 grams per tonne gold (George Cross Newsletter No. 186, 1990).
