Several gold and base metal indices are listed in the region north of Amos
(Figure 4). The mining district of Amos-Senneterre is characterized by two main types of
mineralization: 1) volcanogenic massive sulphide lenses characterized by high levels of
copper and silver, and by sub-economic zinc grades (Jay-Copper Zone) and 2) quartz veins
orogenic auriferous (Duvay, Fontana, Raymor ...). The Arthur Lake Group contains horizons of
rhyolite harboring several known massive sulphide lenses, such as the "Jay Copper" zone (122 000 t
@ 1.4% Cu and 21.0 g / t Ag, 1992, GM 52074). The Lac-Arthur group also contains
numerous gold showings, including the Duvay index (probable reserves of 6.66 M t @ 2.06 g / t
Au, 1991, Canadian Mines Handbook 1995-96), the Fontana Index (Probable Reserves of 968 000 t @
5.83 g / t Au, 1990, Canadian Mining Handbook 1990-91), and the Standard Gold Index (Reserves 132,750
t @ 5.43 g / t Au, 1988, GM 46956).
The host lithologies of gold mineralization in the region include volcanic rocks
felsic to intermediate, basic sills and sills and granodioritic intrusives. The
The main gold showings of interest are described below, according to Bourque, 1988 (GM 47471):
• The Standard Gold Deposit (New Goldvue), located 8 km east of the property, consists of
vertical N-S quartz veins located between subvertical EW shears in a
diorite highly carbonatized. Gold is native and distributed erratically in some veins.
The Fontana gold deposits, located 7 km from the Tung property, consist of
directional quartz N015 to N025, hosted in granodiorite and in
