AbstractAn indicator mineral study was carried out around the Mount Pleasant Sn-W-Mo-Bi-In deposit as part of the Geological Survey of Canada's (GSC) Targeted Geoscience Initiative 4 (TGI-4), a collaborative federal geoscience program with a mandate to provide industry with the next generation of geoscience knowledge and innovative techniques that will result in more effective targeting of buried mineral deposits. This indicator mineral study is one of the first systematic case studies around a major Sn-W deposit in glaciated terrain. It is also the first indicator mineral case study in any terrain to identify a broad range of indicator minerals for this deposit type, in addition to cassiterite and wolframite. Indicator minerals recovered from till at the Mount Pleasant deposit include the main ore minerals, cassiterite, wolframite, and molybdenite, as well as fluorite, topaz, galena, arsenopyrite, and loellingite in the 0.25-0.5 mm, >3.2 SG fraction. Useful indicator minerals in till also include secondary Pb sulphate minerals beudantite (PbFe3(AsO4)(SO4)(OH)6) and anglesite (Pb(SO4)), which formed from the oxidation and weathering of galena.
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 describes an indicator mineral study that was carried out around the Mount Pleasant Sn-W-Mo-Bi-In deposit as part of the Geological Survey of Canada¿s Targeted Geoscience Initiative 4. This indicator mineral study is one of the first systematic case studies around a major Sn-W deposit in glaciated terrain. It identified indicator minerals that can be used to explore for Sn-W deposits in the region and elsewhere in Canada.
