Several skarn related showings occur in or adjacent Sihun Creek, just over a kilometre from the old Iron Hill mine (92F 075).

The area is underlain by Upper Triassic Vancouver Group, Karmutsen Formation volcanics.

The showings consist of:

(1) Massive magnetite in greenish volcanics.

(2) Chalcopyrite, pyrite, epidote, malachite and magnetite in altered and fractured volcanics.

(3) Quartz and calcite veins, in altered and fractured volcanics, containing chalcopyrite, pyrite and malachite.

(4) Garnetite with minor chalcopyrite and malachite.

In 1988, a sample of No.4 type assayed 11.19 per cent iron and 0.62 per cent copper (Assessment Report 18870).

In 1984 and 1985, Brinco Mining completed a program of geological mapping and rock sampling on the area as the Bold claims. In 1988, the area was prospected and sampled by J.P. Loiselle.
