Geochemical Data from the Long Lake Group, Central Newfoundland

J.G. Hinchey

St. John’s, Newfoundland, February, 2015

Abstract

This Open File release consists of whole-rock geochemical data from rock samples collected from the Long Lake group, central Newfoundland (NTS 12A/06 and 12A/10). Samples were collected from outcrop and from diamond-drill cores as part of a mineral deposit study focused on volcanogenic massive sulphide (VMS) potential of the group. The group is host to one defined VMS deposit, the Long Lake deposit, with current indicated reserves of 407 000 tonnes with grades of 7.82 % Zn, 1.58 % Pb, 0.57 % Cu, 49 g/t Ag and 0.57 g/t Au (Keller and Bernier, 2012); as well as numerous other showings and indications. Although this report does not provide an interpretation of the data, the geological context of these rocks, a description of the regional stratigraphy, and a preliminary interpretation of the geochemical data are contained in a report by Hinchey (2014).
