 | A unique diamond and gold deposit has been located near the Arctic coast, about 155 kilometres southeast of Kugluktuk in Nunavut. The deposit bears "striking" similarities to the world's largest, most dominant source of gold, the Witwatersrand Goldfields in South Africa. Rocks are 2.85b years old. Conglomerate samples contained diamonds. |  |

 In April 2019 Silver Range collected a panel sample of the TRC that returned assay results of 36.3 (g/t) gold. | In 1997 geologist Valerie Jackson collected samples from the Tree River Conglomerate 3.1 km NW of Cracker Lake. Tree River Conglomerate is an Archean metasedimentary rock unit in the Anialik Greenstone Belt within the Kitikmeot Region of Nunavut. The known exposures of the TRC are on permits staked on Silver Range's (SNG.v) Tree River Property and on adjacent Inuit Owned Lands. Parcel CO-69. |  The samples were processed to recover zircons and very unexpectedly yielded three diamonds. The discovery wasn't verified until recently. |
TRC contains “abundant” pyrite and is anomalous for high-grade gold. |
 | "Pearson remembers the precise moment about a year later, when the council's Cristiana Mircea, who visits Edmonton to teach Diamond Exploration Research Training School (DERTS) students about diamond indicator mineral identification, matter-of-factly told him the sample produced three diamonds. "My jaw hit the floor," said Pearson. "Normally people would take hundreds of kilograms, if not tons of samples, to try and find that many diamonds. We managed to find diamonds in 15 kilos of rock that we sampled with a sledgehammer on a surface outcrop." https://www.eurekalert.org/pub_releases/2020-10/uoa-dfw100620.php |
