Dec 07, 2005 (B Nelson) - The Cavers Hill area is underlain by Neoarchean granitic and gneissic rocks as well as intermediate to mafic intrusive rocks. Pegmatite veins are present throughout the area. Quartz-epidote vein systems as well as mafic dykes intrude the area. The Fournier occurrence is a sulphide-quartz rich shear zone up to 2.5 m wide. This zone strikes 276 degrees and dips 45 degrees to 68 degrees north. The footwall is a biotite schist, which is possibly a deformed and altered mafic dyke or intrusive. The schist displays an augen texture. Numerous granitic stringers and dykes cut the area.

Dec 07, 2005 (B Nelson) - Mineralization consists of a pyrite-biotite-quartz schist with up to 30% pyrite in places. While no base metal mineralization was observed by staff of the Schreiber-Hemlo Resident Geologist's Office, stripping in the area has reportedly exposed chalcopyrite and galena. Samples collected by Resident Geologist personnel yielded: 87-BFO-3: 35 ppb Au, 5ppm Ag, 253 ppm Cu, 22ppm Ag, 7ppb Pt and 5ppb Pd. 87-BFO-5: <2 ppb Au, 4ppm Ag, 378 ppm Cu, 475 ppm Zn 87-BFO-7: <2 ppb Au, 4ppm Ag, 640 ppm Cu, 184 ppm Zn.
Apr 29, 2019 (Therese Pettigrew) - The text of assessment report 42D13NE0004 indicates that assays of up to 0.17 oz/t Au over 30 inches (5.83 g/t Au over 76.2 cm) were returned from DDH 4, but the assay certificates included in the report only show assays of up to 0.008 oz/t Au (0.27 g/t Au).
Dec 07, 2005 (B Nelson) - The footwall is a biotite schist, which is possibly a deformed and altered mafic dyke or intrusive.
