The Tsa Da Glisza property is located in the southeastern Yukon, Canada. The property is comprised of 105 claims covering 21 square kilometres. The property is 100% owned by True North Gems.
Emeralds were found on the property in 1998 and True North Gems began work on the property in 2001. Activities over the next five years include soil sampling, silt sampling, prospecting, geological and structural mapping, diamond drilling, trenching, and bulk sampling and processing in the on-site plant.
Emeralds are found over a distance of 903 metres with a 200 metre elevation range. They are located in and adjacent to quartz-tourmaline veins which cut chlorite-rich schist. The Creataceous-age granite and the critical juxtaposition between elements in the veins (specifically beryllium, Be) and the wall rock (chromium, Cr), allows emeralds (the green variety of the mineral beryl) to crystallize.
In 2011, after several years of in-activity, the Company re-assessed the project and decided that although the exploration to date had indeed confirmed the presence of significant quantities of emerald on the Tsa da Glisza project, the Company’s resources were best used in the development of the Aappaluttoq Project in SW Greenland. As such, site reclamation and remediation was completed in the period 2011-2014.
