The partners say more than 50 new gold occurrences have been discovered in the belt in the past 15 years, hosted in structures related to the contact between Timiskiming sediments and Keewatin volcanics. The belt and surrounding area (comprising the eastern Shebandowan greenstone belt) were recently the focus of a Quaternary mapping and overburden sampling program by the Ontario Geological Survey. This work outlined several gold targets in the study areas, including the locale of the Bylund occurrence, based on their gold-grain content in glacial till. The pristine shape of many of the gold grains suggests a nearby source, the partners say.
Recent trenching down-ice of the anomalous till sites uncovered a deformation zone consisting of numerous shear-fracture zones characterized by intense iron carbonate, sericitic, albitic and silicic alteration.
The alteration zones contain quartz veins and stockwork with pyrite and arsenopyrite, and are associated with a strong induced-polarization anomaly. Channel sampling of this zone returned values of 4 grams over 14 metres, 1.1 gram over 4.1 metres and 123 grams over 0.5 metre.
