Metallogenic overview of the Nain Province, northern Labrador

Abstract The Nain Province (NP) of northern Labrador is a >600 km long by =100 km wide Archean craton that has undergone relatively little mineral exploration until economically significant concentrations of orthomagmatic nickel sulphide were discovered by Diamond Fields Resources (DFR) at Voisey’s Bay. Due to the great time span between crust formation and final intrusive activity (ca. 3.9 Ga to 1.27 Ga),
there were, however, numerous metallogenic events within the NP. The NP was intruded by the ca. 1.3 Ga to 1.2 Ga Nain Plutonic Suite (NPS) composite anorthosite-granite complex. The NPS divides the NP into the southern Hopedale Block (90 km by 150 km) and the northern Saglek Block (375 km long by =50 km wide). These two blocks appear to represent two distinct Archean cratonic nuclei, each with its own distinct metallogenic history. The NPS is a coalesced assemblage of composite intrusions which include anorthosite, troctolite, norite, gabbro and granite.

Summary: At the 1992 PDAC Convention, Norman Keevil announced the formation of the Exploration Technology Division (ETD) of the Mining Industry Technology Council of Canada (MITEC). It was evident that base metal reserves in Canada were declining and that the cost of discovering a deposit in Canada was increasing. Coordinated research to develop new exploration technologies was required to discover the next generation of orebodies. The ETD was formed in response. The mission of the ETD is to contribut...

Summary: Mineral exploration in Canada traditionally has gone from boom to bust in cyclical patterns following market and discovery cycles, but other endemic factors related to exploration financing and performance have contributed to the amplitude and recurrence of these fluctuations. In view of these problems, junior exploration is reviewed here in a marketing perspective, looking at the 4 Ps: Product, Price, Placement and Promotion.
In the 1980s, MEDA incentives gave the shares of junior and mining...
