Capsule Geology

The Ho occurrence area, south of Yeth Creek, is underlain by Lower Jurassic Inklin Formation (Laberge Group) comprised of a thick, sedimentary sequence predominantly shale, siltstone, and greywacke. The Inklin sediments outcrop south of the Nahlin fault which approximates the boundary between the Inklin Terrane to the south and the Cache Creek Terrane to the north. Rhyolite of the Early Eocene Sloko Group and quartz dioritic intrusions of the Late Cretatceous Windy Table Complex are mapped in the Ho area. Feldspar-porphyry dykes of the Paleocene to Eocene Sloko-Hyder Plutonic Suite intrude the Inklin strata.

The Inklin sediments are well bedded and consist of uniform siltstone, shales, and greywackes. Some hornfelsed sediments occur near the intrusive margins and show disseminated pyrrhotite and pyrite which weathers rusty brown. Fault bounded areas in the sediments show slight hematitic alteration and intense carbonate and clay alteration.

Rhyolite and feldspar porphyry dykes intrude the sediments and show pyritization near the contacts and within the dyke itself. The dykes range from 0.6 to 4.5 metres in thickness. Some are associated with siliceous breccias.

Pyrite mineralization occurs within quartz veins which crosscut the sediments.

In 1984, one rock sample from quartz veining in the Inklin sediments along a north flowing tributary of Yeth Creek assayed 0.285 grams per tonne gold, 0.12 per cent arsenic and greater than 0.1 per cent antimony. Two other rock samples taken within the Inklin sediments to the west, assayed 0.9 grams per tonne gold and 0.325 grams per tonne gold, respectively (Assessment Report 12797).

In 1982, stibnite needles were found on fracture faces within the Inklin sediments exposed on the north side of Yeth Creek (refer to Waterfall, Goat 104K 067).

In 1984, Chevron Minerals Ltd staked the Ho and Hum claims and collected 295 soil and 30 rock samples.

In 2005, geological field reconnaissance mapping and rock sampling (29 samples) was carried on the Fall property, consisting of eight claims in the northern part of the Kizmet project area, a joint venture between Barrick Gold Inc and Rimfire Minerals Corporation. The Fall claims covered the Waterfall (104K 067), Ho (104K 111) and Goat (104K 046) showings. No samples were taken at the Goat during the program. Of the 29 rock samples collected on the Fall property, only a few yielded anomalous results (Assessment Report 28090). One grab sample taken near the Waterfall showing contained blebs of pyrite and veinlets likely to be sphalerite and yielded 6.1 grams per tonne silver. A float sample collected near the Waterfall showing yielded 3.3 grams per tonne silver and 0.2 per cent zinc. One float sample taken near the Ho showing yielded 1.3 grams per tonne silver.
