From introduction: The "Granite" exploration hole was core drilled to determine the character of the igneous rocks from the surface to a depth of 1,200 feet and the degree of structural anisotropism of the rock within 200 feet of a point 950 feet below the surface. This report summarizes the data on the structure, chemistry, petrology and alteration of the rocks exposed at the surface in the immediate vicinity of the drill site and in the core.
