Indicator mineral abundance data for a bedrock sample from the Little River antimony occurrence, Newfoundland and Labrador

Abstract

As part of the Geological Survey of Canada's Targeted Geoscience Initiative 4 (TGI-4) Program, one bedrock sample was collected from the Little River antimony occurrence in southern Newfoundland to determine the indicator minerals that are indicative of Sb deposits. The purpose of this open file is to report the raw indicator mineral weight and abundance data for the bedrock sample collected in 2012 for this case study. The sample was processed using a combination of tabling, panning, and heavy liquids to recover potential indicator minerals. Sample location, weights of various fractions produced during sample processing, and indicator mineral grains identified are reported in this open file. Two Sb minerals were recovered from the bedrock sample, stibnite and stibiconite, as well as gold, arsenopyrite, and pyrite. This study provides 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.
