The ONO showing is an orange-red gossan on the north side of Shazah Creek, approximately 4 kilometres upstream from the confluence of Shazah Creek and Tulsequah River. The location is approximately 88 kilometres south of Atlin, B.C.

The area is underlain by a Paleozoic to Lower Triassic volcano-sedimentary belt which extends north-northwest and consists mainly of andesitic to felsic flows, tuffs, breccia, and minor sedimentary limestone, chert, and siltstone. These are intruded by a Tertiary-Cretaceous quartz monzonite pluton which is thought to be correlative with the Sloko Group volcanics. The volcano-sedimentary rocks have undergone regional greenschist facies metamorphism.

On the property the rocks are divided into two packages, one dominated by andesitic sediments and tuffs with prominent limestone intervals and the other dominated by felsic volcanic rocks mixed with volcanogenic sulphides occur in both packages.

The southwest part of the property is underlain by meta-rhyolites which consists of pale green, foliated and well lineated quartz-muscovite-chlorite schists with pyrite lenses up to 2 centimetre thick and 2 metres long. These lenses parallel the bedding. Well developed isoclinal folds are developed in the limestone units. Lower greenschist metamorphism affects the sequence commonly altering rhyolite to quartz sericite schist and recrystallizing limestone to coarse grained marble.

In the south part of the property, massive rhyolite and dacite predominated with minor welded tuffs.

Massive sulphide zone, about 30 centimetres wide, occurs in banded and brecciated rhyolite along Shazah Creek. Sulphides consists mainly of pyrrhotite with scattered patches of chalcopyrite. In 1981, a sample returned 0.069 grams per tonne gold, 1.37 grams per tonne silver, 0.24 per cent copper, 0.01 per cent lead, and 0.01 per cent zinc (Assessment Report 9007).

Near the contact with the monzonitic intrusive, bedded rhyolites are heavily pyritized.

Exploration work conducted by Ecstall Mining Corp. in 1990 rock sampled and soil geochemed three gossan zones on the north side of Shazah Creek. At the east end of the main Shazah gossan (Shazah Gossan #1) 1 to 2m wide zones of semi-massive sulphides are exposed for 50m along a cliff face. Shazah Gossan #1 chip samples contained 20% pyrite-pyrrhotite-pentlandite and trace to 1 % chalcopyrite in a dark green andesitic tuff host rock. Analyses of these samples show anomalous Cu and Ni (TQCR-091,093,094). Sample TQMBR-278 was anomalous in Ag, Cu, Pb, and Zn. The most promising results from the 1990 exploration program are in the area of the large gossan on Shazah Creek ONO. Contour soil anomalies indicate a reasonably large area of anomalous Cu, Ag (Assessment Report 20657).
