| Abstract | There are a number of ongoing research projects at the Geological Survey of Canada (GSC) with the objective of enhancing exploration success through the identification of new indicator minerals hosted
within, or associated with, a variety of mineral deposit types. These indicator minerals can be recovered from glacial sediments and traced back to their bedrock source as an effective mineral exploration method in glaciated terrain. As research on
indicator minerals evolves, quality assurance and quality control (QA/QC) measures must be implemented to ensure that 1) in the field, samples are not contaminated from external sources or from other samples; 2) during sample processing and indicator
mineral picking, loss of indicator mineral grains is minimized (close to zero), crosscontamination before and among sample batches does not occur, and minerals are correctly identified; and 3) all reported indicator mineral data include adequate
metadata for future reference and comparison. To fulfill these needs, protocols have been developed for ongoing and future research projects at the GSC to ensure indicator mineral data are of the highest quality. These protocols satisfy the
requirements of National Instrument 43-101 (2005), which specifies that technical information reported by exploration and mining companies in Canada (such as indicator mineral data) must include details of the quality assurance program being
implemented. These short course notes have been prepared specifically for short course SC07 Application of Indicator Mineral Methods to Mineral Exploration offered at the 26th International Applied Geochemistry Symposium, November 2013, in Rotorua,
New Zealand. The notes have been presented in a similar workshop offered at the Prospectors and Developers Association of Canada (PDAC) Conference, March 2013 in Toronto, Canada (Plouffe et al. 2013) but have been revised based upon constructive
comments received at PDAC workshop, and more recent results obtained as part of on-going GSC projects. |
| Summary | (Plain Language Summary, not published)
Specific minerals found in glacial sediments are clearly indicative of different types of potential mineral resources in bedrock (e.g. gold, diamonds,
copper, lead, zinc, etc.). These are called indicator minerals because they are indicative of the mineralization (potential natural resource). Analysing glacial sediments for indicator minerals is a method that works well at detecting mineral
resources. For this method to be applied properly, protocols have been developed at the GSC to ensure that the analytical results are to the highest standards. The protocols are outlined in these notes to be presented at a wide range of stakeholders
within the private and public sectors who are also doing indicator mineral research. |
