Capsule Geology

The Ronoke showings are located 7 kilometres northeast of Ymir on Ymir Creek. The claims were crown granted in 1901 and several open cuts and 3 adits have been developed.

The area is underlain by biotite granodiorite of the Middle to Late Jurassic Nelson Intrusions. Metamorphosed sediments of the Lower and Middle Ordovician Active Formation (Pend d'Oreille schists) occur in a roof pendant within the Nelson batholith.

The occurrence comprises two showings, the upper (on Lot 3402) and the lower (Lot 3718).

The lower showing, on the south side of the creek, comprises the dumps for 2 caved adits and a few open cuts. Mineralization consists of quartz veinlets with disseminated pyrite and traces of galena and chalcopyrite in silicified, rusty altered hornblende-biotite schist and quartzite. Intrusives host minor disseminated pyrite. An average of 6.9 grams per tonne gold (based on a price of $35.00 per ounce) was calculated from 5 assays across 12 metres (Assessment Report 6141).

The upper showing, 300 metres upstream from the lower showing on the north side of the creek, consists of a small outcrop and a caved adit. Mineralization is similar to the lower showing and is reported to "replace" or follow certain beds within the schists. Graphite is locally abundant. An assay of 39 grams per tonne gold came from this zone (also based on $35.00 per ounce) (Assessment Report 6141).
