Nov 26, 2019 (Therese Pettigrew) - The Burnell Showing is the possible source of angular, gold-bearing float approximately 600m southwest of, and down ice from, the showing. The showing is a mafic metavolcanic unit that is 160m east of and stratigraphically above, the extrapolated location of the composite sill that is the uppermost part of the Off Lake Felsic Dike Complex. The host rock is dominantly a magnetic and relatively massive mafic unit. A major structural control on the location of mineralization appears to be an early fault trending between 000 deg and 015 deg and located in the short valley immediately west of the showing" (Assessment report 20000004281).

Nov 26, 2019 (Therese Pettigrew) - Late in the 2007 field season, a mineralized boulder train was discovered along the southern perimeter of the Northern Peninsula on the northeast shoreline of Off Lake. For example, grab sample #804497 (440325E, 5417060N) returned gold-rich VMS-style mineralization which included 4.67g/t gold and 7.66% zinc. Prospecting, 'up-ice' from this peninsula in 2008, resulted in the discovery of two new sulphide occurrences referred to as the Burnell Showing and the BB Showing. Drill holes OL09_08, OL09_10 and OL09_11 were spotted to test the Burnell Showing. The main lithologies intersected were early and late felsic dikes, quartz veining, Off Lake Felsic Dike Complex lithologies and mafic to intermediate volcanics. Strong magnetic susceptibility readings were reflective of mafic volcanic lithologies. Mineralization consisted essentially of very fine grained ubiquitous disseminated pyrite with rare specks of chalcopyrite. DDH OL09-08 assayed up to 0.161 ppm Au and 3310 ppm Cu. DDH OL09-10 assayed up to 1.205 g/t Au, 3030 ppm Cu, 3800 ppm Pb, and 5690 pm Zn over 0.78m (71.00m-71.78m) (Assessment report 20000004281). DDH OL10-03 returned assays up to 2980 ppm Cu and 0.081 ppm Au (Assessment report 20000004698).
