Presents the results of mapping and detailed follow-up geological study of an area of the south central Cape Breton Highlands located north-east of Margaree Centre. The area occurs at the eastern margin of the proposed Aspy Terrane and locally includes the Precambrian Kathy Road dioritic suite of the Bras d'Or Terrane. Sections of the report cover the lithology of Precambrian to Carboniferous rocks, shear zones and brittle faults, mineral occurrences, miscellaneous mineralization and alteration zones, contact relations and relative ages of rock units, geologic structure, regional deformation and folding, and metamorphism.
