field sites

 
 

PetraDiamonds' Cullinan Mine, South Africa.  This mine is over 100 years old and has produced an enormous number of diamonds including the Crown jewels.  We had great access to their underground kimberlite mines as well as their old and new tailings facilities.  Great thanks to all the people at Cullinan for the opportunity.  

 

De Beers' Venetia Mine, South Africa.  International team of CO2 mineralization experts conducting fieldwork . Ongoing research is aimed at characterizing kimberlite residues and conduct laboratory technology demonstrations.

 
 
 
 

De Beers' Gahcho Kué Diamond Mine, Northwest Territories, Canada.  These kimberlite residues have the potential to sequester carbon dioxide and offset the greenhouse gas emissions of mining.

 
 
 
 

Atlin, British Columbia, Canada.  Exploring Monarch Mountain, ultramafics, serpentinization, and carbonation. The serpentinized harzburgite is a remnant of ancient oceanic crust.

 
 

ATLIN carbonate PLAYAS

These playas are natural analogues for sequestration of carbon dioxide within Mg-carbonate minerals.  Field sampling was conducted in 2004, 2005, 2007, 2011 and 2012.  Check out publications by Power et al. (2007, 2009 and 2014).

MOUNT POLLEY MINE

Mount Polley Mine was the site of a massive tailings spill in 2014.  Sampling was conducted in 2016.

 
 

CLINTON CREEK ABANDONED MINE

This abandoned mine host approximately 11 million tonnes of chrysotile mine wastes that have sequestered over 100,000 tonnes of carbon dioxide.  Field campaigns were undertaken in 2004, 2005, 2007 and 2011.  For more information, see publications by Power et al. (2010, 2011b) and Wilson et al. (2009).

SWIFT CREEK SERPENTINITE LANDSLIDE

This landslide is a natural analogue for the weathering of ultramafic mine tailings.  The landslide advances several metres per year.  The serpentine minerals have weathered to form magnesium carbonate and pyroaurite.

 
 

MOUNT KEITH NICKEL MINE

This mine is located in Western Australia and produces approximately 11 million tonnes of mine tailings per year.  Field sampling and laboratory analyses have revealed that approximately 40,000 tonnes of CO2 are sequestered each year.  See publications by Power et al. (2011a), Bea et al. (2012) and Wilson et al. (2014).

DIAVIK DIAMOND MINE

The Diavik mine is located in the Northwest Territories, Canada.  These ultramafic mine tailings sequester carbon dioxide as they weather.  See publications by Wilson et al. (2011) and Power et al. (2011a).
