AbstractTill and bedrock sampling was conducted during the summer of 2007 around the Halfmile Lake Zn-Pb-Cu volcanogenic massive sulphide deposit, Bathurst Mining Camp, northern New Brunswick, as part of the Geological Survey of Canada's Targeted Geoscience Initiative-3 (TGI-3). The overall purpose of this study was to document the indicator minerals and their compositions in till and bedrock that are characteristic of a volcanic-hosted massive sulphide deposit. Data are reported in two parts: Part 1 includes the bedrock indicator minerals, and Part 2 the till indicator minerals. The potential indicator minerals identified in mineralized bedrock samples from the Halfmile Lake deposit included chalcopyrite, sphalerite, galena, pyrite, ferro- and nonferromagnetic pyrrhotite, arsenopyrite, magnetite, gold, goethite, and beudantite. These minerals showed distinct characteristics either in their abundances or chemical compositions that make them viable indicator minerals. Many of these minerals are susceptible to degradation under surface weathering conditions and glacial transport, and these processes would inhibit the deposition and/or preservation of these minerals in surface till. Other trace sulphides and oxides that were identified are not abundant enough, too fine-grained, or too common.
Summary(Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI-4) is a collaborative federal geoscience program that provides industry with the next generation of geoscience knowledge and innovative techniques to better detect buried mineral deposits, thereby reducing some of the risks of exploration. This open file reports bedrock heavy mineral data for samples collected from and around the Halfmile Lake VMS deposit in the Bathurst Mining Camp, New Brunswick.
