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.
