Drainage surveys and airborne geophysical surveys of a
600 km2 area from Blair Atholl to Braemar identified
several targets near Glenshee within the Ben Eagach
Schist, the host formation of the Aberfeldy deposits, lying
30 km along the Dalradian strike to the SW. Integrated
geological, geochemical and geophysical surveys have
been carried out over these targets. The extensive cover of
peat and glacial overburden, particularly over the softer
lithologies of the formation, hinders geological mapping
and near-surface leaching has destroyed most of the
sulphide. The presence of base metals and baryte is best
shown by detailed drainage sampling and the sulphidebearing
graphitic schist can be traced through drift
covered ground by VLF-EM, IP and SP surveys. Six
shallow boreholes were drilled on the basis of the
geochemical and geophysical anomalies and mapping of
the available outcrops.
Zinc-lead mineralisation has been found in the elastic
lower member of the Ben Eagach Schist as well as in the
upper member of graphitic schist. Vein baryte with minor
base metals is present in the Ben Lui Schist, a higher
Middle Dalradian formation, in southern Glenshee.
The detailed information available for the Glenshee
area is listed in the Data Package. A charge of &lOOO will
be made for a copy of this information, consultation with
staff, drillcore examination and for the time of staff required
to make a short field visit to the area
