Capsule Geology

The Fran showing is located about 10 kilometres south-southwest of Endako and is on the Endako mine (093K 006) property.

The geology of the region consists of: 1) a Mississippian to Triassic Cache Creek Group oceanic volcanic and sedimentary assemblage 2) the Upper Triassic dominantly mafic volcanic Takla Group 3) the Lower to Middle Jurassic Hazelton Group mafic to felsic volcanic and sedimentary rocks 4) the Upper Cretaceous to Lower Tertiary Ootsa Lake Group sedimentary and volcanic rocks and 5) the Oligocene and Miocene Endako Group. The region has been intruded by the Lower Jurassic quartz monzonite to granodiorite Topley Intrusive Suite, Upper Jurassic plutons of the Francois Lake Suite and plugs and stocks related to Upper Cretaceous and Tertiary volcanism.

The area is underlain by part of the Francois quartz monzonite phase of the Francois Lake batholith. This is one of five phases recognized on the basis of texture and composition.

Disseminated molybdenite with more abundant pyrite occurs within the quartz monzonite.

Work History

In 1963 and 1971, Utica Mines Ltd. completed programs of soil sampling and geological mapping on the area as the Rob 1-22 claims.

In 1974, Dankoe Mines Ltd. completed four percussion drill holes, totalling 274.0 metres, on the Fran and Rob claims. Drilling yielded up to 0.017 per cent molybdenite over 6 metres in hole P-2 (Assessment Report 5055). No location map of the drillholes was provided.

In 1976, Dankoe Mines completed two diamond drill holes, totalling 152.0 metres, on the Fran and Rob claims.
