[{"type":"text","content":"Diamonds and Gold Discovered in Tree River Conglomerate in Nunavut, CanadaHighlights:A University of Alberta research team has recovered three alluvial, kimberlitic diamonds from two small, separate samples of the Tree River Conglomerate following up on a previous discovery. Panel sampling of the Tree River Conglomerate by Silver Range returned up to 36.3 g/t Au from a one-metre by one-metre sample.Zircon dating conclusively dated the Tree River Conglomerate at 2.9 Ga, in the \"Great Gold Deposition Window\" postulated for gold deposition in the Pilbara and Witwatersrand.VANCOUVER, BC / ACCESSWIRE / October 7, 2020 / Silver Range Resources Ltd. (TSXV:SNG) (\"Silver Range\" or \"Company\") is pleased to provide an update on exploration work conducted by the Company at its Tree River Property in the Kitikmeot Region, Nunavut; and on surprising research work results from the Tree River Conglomerate recently released at the American Geophysical Union annual general meeting.The Tree River Conglomerate (\"TRC\") 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 as Silver Range's Tree River Property and on adjacent Inuit Owned Lands (\"IOL\") Parcel CO-69.Diamonds recovered from the Tree River ConglomerateDuring 1997, noted northern geologist Valerie Jackson collected samples from the TRC approximately 3.1 km NW of Cracker Lake while conducting regional mapping of the Anialik Lake Greenstone Belt. The samples were processed to recover zircons for dating purposes and unexpectedly yielded two suspected diamonds. The discovery was never verified.In 2018, Drs. Graham Pearson and Jesse Reimink of the University of Alberta and Pennsylvania State University, respectively, conducted follow-up work in the area. They collected two 10 kg samples from the general area of the 1997 sampling and recovered 2 diamonds from one sample and a third diamond from the second sample. In a meeting abstract published on October 6, 2020 by the American Geophysical Union (link) they reported that:\"The three recovered diamonds (< 210 μm) have (cubo-)octahedral morphological features and have nitrogen contents ranging from <10 ppm (n=2) up to 1770 ppm N (Type IaA), the latter having positive δ15N (+3.1 to +4.4&permil;).
