The Dinah occurrence is located approximately 88 kilometres east of Dease Lake.

The prospect is a stratiform deposit consisting of disseminated galena and sphalerite in limestone and laminated galena and sphalerite in silty to siliceous mudstones. The rock units described on the property from youngest to oldest are:

Unit 11 - Chlorite schist with up to 3 per cent magnetite.

Unit 10 - Mudstone with interbeds of black shale. The mudstone contains laminated galena and sphalerite.

Unit 09 - Shale with interbeds of black mudstone and subunits of schist and limestone (the limestone subunit contains minor

sphalerite).

Unit 04 - Graphitic black shale.

Unit 05 - Porous siliceous mudstone with limestone and schist subunits.

Unit 06 - Mudstone with coarse-grained galena in discontinuous pods. It contains two subunits made up of grey to buff weathering

limestone, the lower one of which contains pods of sphalerite and galena and bedded sphalerite-galena up to 4 centimetres

thick. A mudstone subunit with thin laminations of fine-grained galena also makes up this unit.

Unit 05 - Schist with minor limestone subunit.

Unit 04 - Shale with black laminated mudstone.

Unit 03 - Mudstone with turbidite lenses.

Unit 02 - Shale with minor interbeds of mudstone.

Unit 01 - Limestone and schist.

According to a recent geological compilation of the area, the Dinah occurrence is underlain by rocks of the Ordovician to Mississippian Road River Group.

In 1982, a 0.5 metre section of drill core taken at 57.4 metres in diamond-drill hole 82-7 assayed 4.56 per cent lead, 5.66 per cent zinc and 16.80 grams per tonne silver (Assessment Report 10877).

The Dinah was originally discovered by J. Kubiak and prospected by him for about 10 years before selling his interest in the property to Queenstake Resources in 1980. In 1981, Queenstake conducted some geochemical surveys and then optioned the property to Eldorado Minerals and Petroleum in 1982. In the same year, Eldorado conducted a program of extensive exploration which included 570 metres of trenching and 1378 metres of diamond drilling in 10 holes. The original lead-zinc showings on the property are about 2 kilometres southeast of where the 1982 drill activity intersected more definitive stratiform lead-zinc mineralization. Favourable units were followed along strike to the northeast where siliceous mudstone in Faulkner Creek canyon was found to contain laminated galena and sphalerite (see Bow 25, 104I 086). This location, about 6 kilometres northwest of the 1982 drill area, indicates that stratiform lead-zinc mineralization occurs along a strike length of 8 kilometres. In 1985, Eldorado conducted a small exploration program consisting of 100 metres of trenching.
