Dec 07, 2005 (A Wilson) - Coarse disseminated pyrite and chalcopyrite occur within the shear zone. A number of small quartz stringers also occur within the shear zone. Grab samples taken in 1933 returned assays of 53 g/t Au, 63 g/t Au, 125 g/t Au and 300 g/t Au. One additional sample returned a value of 4.8% Cu. Grab samples collected by Gogama Resources returned between trace and 5.7 g/t Au.
Oct 17, 2013 (P Bousquet) - - Samples taken from the trenches returned assays of up to 0.167 oz/t (T-2945 / 2.7838). The sample shows quartz stringers with 2% pyrite within the silicified trondhjemite.
