TGI-4 Indicator Mineral Research Project, 2010-2015

Project Description

Few studies have been published that document indicator mineral signatures of intrusion-hosted W-Mo deposits, and none that document indicator mineral signatures of Sb mineralization.  To address these knowledge gaps, till, stream sediment and bedrock samples were collected around the Sisson W-Mo deposit and the Mont Pleasant Sn-W-Mo-Bi-In deposit (till and bedrock only) in New Brunswick.  One bedrock sample was collected from a surface trench at the Little River Sb occurrence in south-central Newfoundland.

The objectives of this project are: 1) to determine the indicator minerals and their trace element signatures that are indicative of intrusion-hosted W-Mo deposits; 2) to establish practical methods for their recovery from glacial sediments and their identification that can be routinely applied in W-Mo exploration in glaciated terrain; and 3) to provide preliminary insights into the physical appearance, size, and abundance of Sb-rich minerals which will help in the future identification of Sb-rich indicator minerals in unconsolidated surficial sediments.

Project Funding

The Targeted Geoscience Initiative 4 (TGI-4; 2010-2015) is a collaborative federal geoscience program that provides industry with the next generation of geoscience knowledge and innovative techniques, which will result in more effective targeting of buried mineral deposits.
