[{"type":"text","content":"Talon Completes Initial Pre-Concentration Test Work and Increases Lower Grade Mineralization by 107% to 1.18% NickelRoad Town, British Virgin Islands--(Newsfile Corp. - March 25, 2020) - Talon Metals Corp. (TSX: TLO) (\"Talon\" or the \"Company\") is pleased to provide an update on the Tamarack Nickel-Copper-Cobalt project (\"Tamarack Project\"), located in Minnesota, USA. The Tamarack Project comprises the Tamarack North Project and the Tamarack South Project.Highlights- Through pre-concentration testing, Talon has successfully shown that nickel sulphide mineralization at the Tamarack Project that is currently below cut-off grade (i.e., below 0.7% Ni) can be upgraded to above cut-off grade.- The feed sample was upgraded from 0.57% nickel to 1.18% nickel (an increase in grade of 107%) in 32.8% of the mass. The overall nickel recovery was 70.6%, which translates to approximately 82% of nickel in sulphides recovery. The copper grade was increased from 0.36% Cu to 0.79% copper at 71.8% recovery.- These results create an opportunity for the Company to include known exploration targets with low-grade sulphide mineralization (i.e., below 0.7% Ni) in future exploration programs, which could significantly increase the overall mineral resource at the Tamarack Project.\"The recoveries for nickel were particularly impressive considering that QEMSCAN mineralogical results indicate that only 85% of the nickel in the rock mass is associated with sulphides,\" said Oliver Peters, Talon Metallurgist.\"We are planning to test a sample representative of disseminated mineralization north of the present mine plan documented in our updated PEA (see Figure 2 below). We plan to also conduct further geotechnical studies to investigate bulk mining methods,\" said Henri van Rooyen, CEO of Talon. \"If economic, our goal is to double the 8 year mine life as presented in our updated PEA.\"Description of Metallurgical Test WorkOn May 9, 2019, Talon announced a test program for the removal of silicate minerals from the coarse-grained ortho-cumulative (\"CGO\") intrusion prior to milling and flotation. The disseminated sulphides in the CGO tend to be relatively coarse and patchy in texture (see Figure 1 below). Heavy Liquid Separation (\"HLS\") testing was therefore performed, which simulates Dense Media Separation (\"DMS\"). DMS is a proven, low-cost separatio...
