Province: Superior
Subprovince: Sachigo
Terrane: North Caribou
Geological Age: Archean
Mar 19, 2007 (A Wilson) - The stratigraphic section consists of Archean-aged, steeply dipping, mafic to felsic volcanic rocks with minor amounts of interflow sediments intruded by sills and small stocks of gabbro and granits. The volcanic units have been isoclinally folded to produce a weak to very strong foliation.

Mar 19, 2007 (A Wilson) - The drill hole intersected a sequence of intermediate to felsic tuffs, crystal tuffs and agglomerates. A mylonite has been interpreted between 180.61 m and 181.56 m.

Aug 01, 2014 (A Wilson) - The drill hole tested a large, strong bull's-eye magnetic anomaly unexplained by two previous drill holes. Mineralization consists of a 4.9 m thick zone of massive magnetite within chlorite-talc altered felsic tuffs. Sparse sulphides are present. The best intersection returned 0.86% Cu over 1.07 m. DDH MCF-10-80 intercepted a massive magnetite + sulphide zone from 165.50-171.80m or a length of 6.3m. The mineralized zone is composed of an upper and lower layer of mostly magnetite (165.50-167.00m and 169.45-171.80m) and a center layer of sulphides (167.00-168.83m). The portion 168.83-169.45m is a non-magnetic country rock with 10cm quartz vein. The magnetite and sulphides occur as fine grained minerals. Pyrites generally comprise the sulphide zones. 8 samples marked 235226 to 235233 were collected from this hole. Of the 8 samples collected for laboratory analysis, 1 sample returned a value of 1.5% Cu
