NOTCHES PROPSPECT
Notches Prospect
The Notches prospect is a 5 km long and 1 km wide, northwest-southeast trending outcrop ridge located 3 km to the southeast of Aamurusko. Prospecting led to multiple gold showings in quartz sub-outcrop. The Notches area is host to an interbedded sequence of mature siliceous sandstones and conglomerates with late cross-cutting mafic to ultramafic and lamprophyre dykes. The southwestern contact is hosted by a suite of mafic to ultramafic volcanic and intrusive rocks and mafic conglomerates but is not well constrained due to lack of exposure. The northeastern contact is possibly intrusion/fault related with an unconformable suite of ultramafic rocks.
Approximately 2,650 grab samples with an average grade of 2.2 g/t Au have been collected from boulders, sub-crops and outcrops. In addition to prospecting and mapping, 27 trenches have been excavated and 6 drill holes have been completed at Notches.
In the area of trench NOT1817 gold mineralization is hosted within a 5-10 m wide conglomerate unit with 1-15 % disseminated sulphides (pyrite-pyrrhotite-chalcopyrite-galena and locally visible gold) and altered by silica, hematite, iron oxide and carbonate. The conglomerate is also cross-cut by flat and steep gold- bearing quartz veins.
