Feb 12, 2021 (Sheree Hinz) - The Breton Breccia forms a pipe-like body underlying an oval-shaped area approximately 1350 feet long and 350 feet wide. The pipe consists of a heterogeneous mixture of fragments embedded in a matrix of coarsely crystalline quartz and carbonate. The fragments are highly angular and range in size from a fraction of an inch to several feet. They are composed exclusively of rocks around in the immediate vicinity of the breccia. This includes granite, diabase, mafic volcanics and felsitic rocks. The contacts of the breccia with the massive wall rock are sharp or are gradational over a few feet.

Feb 12, 2021 (A Pace) - Sulphide mineralization is confined to the matrix and consists of approximately equal amounts of chalcopyrite and pyrite, with minor quantities of sphalerite, galena and other minerals. Recoverable quantities of silver are present, along with gold. Although the sulphides are throughout the breccia they are largely confined to distinct, continuous high-grade zones that were mined selectively. The high-grade ore zones are controlled by a system of domal fractures located in the central part of the breccia. The fracture system contains at least three and possibly four, major ore zones and several subsidiary branches. 1955 drilling by Sylvanite Gold Mines Ltd. gave anomalous copper values as high as 14.47% copper over 5.7 feet. 1961-1964 drilling by Tribag Mining Company Ltd. gave anomalous copper values as high as 10.20% copper over 4 feet. 1963 drilling by Tribag Mining Company Ltd. gave assay values from the V-holes which include 1.4 feet of 2.23% Cu, 0.37% Au, 5.1 feet of 13.44% Cu, 2.49% Ag.
