3D Kimberlite Mineral Chemistry Data from Slave Geological Province to be Released

YELLOWKNIFE (March 28, 2017) – A study will be released this week that reports new Kimberlite Indicator Mineral (KIM) Chemistry in the Central Slave Geological Province that has potential to benefit future exploration in the region to find the next diamond deposits.

This study is planned for release by the Northwest Territories Geological Survey (NTGS) on March 30, 2017 at 8:30 a.m. (MDT).

This is the latest geoscience research arising from the Slave Province Surficial Materials and Permafrost Study that was conducted from 2015-2016, designed to inform a variety of mineral exploration, geological and environmental research objectives.

Two earlier studies provide insight into the till samples collected from the same drilling. NWT Open Report 2016-012 reports till geochemistry from the reverse circulation sampling, and NWT Open Report 2016-018 reports KIM picking results.

Combined, the three reports provide a valuable new 3D till geochemistry and indicator mineral database for use to advance research and mineral exploration interests. The research for the three studies was carried out by the NTGS and funded by the Canadian Northern Economic Development Agency (CanNor).

The Government of the Northwest Territories (GNWT) values geoscience information as a way to inform decision making and increase public awareness. Enhancing the availability of geoscience information is a key component of the NWT Mineral Development Strategy.


“The Slave Geological Province is one of the most promising mining regions in the world and offers significant economic opportunity. Through this innovative 3D geoscience data, we will gain a more accurate understanding of the mineral and surficial potential of this area and demonstrate that the Northwest Territories has world-class resource potential and scientific research needed to attract investment.”
-Wally Schumann, Minister of Industry, Tourism and Investment

Quick Facts 

  • The Slave Geological Province is one of the most promising mining regions in Canada and includes a number of gold, diamond, base metal and rare-earth deposits.
  • The latest data includes KIM chemistry from 12,444 picked mineral grains from the Lac de Gras Area. The individual mineral grains were chemically characterized to determine if they originated from kimberlite – the host rock for diamonds.
  • Surficial sediment sampling via reverse circulation drilling was used to generate the new regional 3D indicator mineral and till geochemistry database for the study area.
