The Mes occurrence is located north of the Mesilinka River, 6 kilometres east of Aiken Lake and approximately 92 kilometres northwest of the community of Germansen Landing.
The hostrocks were referred to as the "problematic unit" by Ferri et al., a fault-bounded section of steeply dipping Paleozoic or Mesozoic sedimentary and volcanic rocks (Fieldwork 1992; Open File 1993-2). Mapping indicates the area to be underlain by basaltic volcanic rocks of the Triassic to Jurassic Takla Group.
Pyrite and minor chalcopyrite are reported to occur in fractures in volcanic rocks that occur near a quartz monzonite intrusion, possibly related to the Lower Jurassic to Lower Cretaceous Hogem Plutonic Suite. Volcanic rocks and pyritic argillites are intruded by granodiorite (Assessment Report 5977).
Work History
In 1975, BP Minerals Limited conducted 11 line-kilometres of induced polarization and resistivity survey covering all claims.
In 1987, Esso Resources Canada Ltd. completed a program of geological mapping and geochemical (rock, silt, soil and heavy mineral) sampling on the area as the Czech 1 claim. A rock sample (CZ-32) of gossanous basalt flow hosting at least 10 per cent pyrite, taken from a creek canyon located approximately 1.2 kilometres southeast of the plotted location of the occurrence, assayed 0.139 per cent copper (Assessment Report 16573).
In 1990 and 1994, programs of geological mapping and geochemical (rock, silt and soil) sampling were completed on the area as the Linka, Czech 1 and Cherokee claims by Ursula Mowat.
