Feb 21, 2017 (Andrew Tims) - The regional scale Burchell Lake Fault passes through the Broadhurst Peninsula and the islands to the south of the Peninsula. The islands to the south and the narrowest portion of the Peninsula show intense structural deformation and have accommodated most of the deformation. In this area strongly to intensely altered felsic metavolcanics show strongly developed S-C fabrics and development of an un-measureable number of fracture plane orientations. Alteration varies from intensely silicified and sericite altered rock to bleaching with strong hematite staining; most mafic minerals in this zone appear to have been altered to chlorite. Foliation and shear fabrics trend northeast dipping steeply to the southeast. A plug of gabbro forms a topographic high where the Peninsula meets the main shoreline. A few narrow red biotite porphyry (lamprophyre?) dykes were found on the peninsula and on the islands to the south. They appear to trend south-southwest and dipping steeply to the west.

Feb 21, 2017 (Andrew Tims) - 2008: Prospecting sample from a shear returned 2 062 ppb Au.
Oct 09, 2018 (Therese Pettigrew) - Burchell Lake Mines Ltd. DDH 1 from 1956 assayed 0.01% Cu over 2.5 feet at 900 feet depth (AFRI 52B10SE0130). On the broad northeast trending portion of the Peninsula a series of quartz-feldspar porphyry dykes trend west and dipping steeply to the north. In the middle of the Peninsula an orange limonitic shear follows the same trend as the porphyry dykes. A 2008 prospecting sample from this shear returned 2062 ppb Au, but samples taken during the 2009 field season returned up to 0.22 g/t Au (sample H369201). This appears to be the same location noted as a copper-gold-silver occurrence on Osmani’s 1997 Ontario Geological Survey map of the area. The 2009 samples from this area did not return anomalous copper or silver, but sample H369201 returned 3740 ppm Zn (AFRI 20000004522).
