(TSXV: GIGA) announced today that, further to its news release dated October 28, 2020, it has filed the associated National Instrument 43-101 Standards of Disclosure for Mineral Projects (NI 43-101) technical report for the Preliminary Economic Assessment (PEA) for its wholly-owned Turnagain Project in northwest British Columbia. The Report is dated November 18, 2020 and can be found under the Company's profile at www.sedar.com and on the Company's web site.The PEA was prepared by Hatch Ltd of Vancouver, Canada with the assistance of Kirkham Geosystems Ltd. (mineral resources), Knight Piésold Ltd. (tailings management), Blue Coast Metallurgy Ltd. (metallurgical testing and process design), Kerr Wood Leidal Associates Ltd. (power supply), and Wood Mackenzie Ltd. (market analysis). Giga is pleased to report there are no material differences between the key results contained in the PEA and the news release dated October 28, 2020.The project is estimated to produce nickel in concentrate with a low greenhouse gas footprint (Scope 1 and Scope 2) of <2.5 t/t Ni over the project life. Should electric mining fleet equipment become available in suitable capacities, the use of such a fleet is expected to reduce greenhouse gas emissions to <0.7 t/t nickel. At these rates, the CO2-sequestering capabilities of the Turnagain tailings may enable the project to be carbon-neutral.The Turnagain PEA demonstrates the potential for establishing a long-life open-pit mine and mill using conventional froth flotation technology to produce high-grade nickel sulphide concentrate. With a phased implementation to a facility with a throughput rate of 90,000 tonnes per day, annual production is projected to average more than 33,000 tonnes per year nickel (73 million pounds per year) for a project life of 37 years. A summary of the PEA highlights is provided in Table 1. The PEA has identified numerous opportunities for project improvement.Table 1 - Turnagain Project PEA Life-of-Mine Results and Assumptions (US$)All parameters annual average except construction and sustaining capital cost Phase 1 (Y1-5) AveragePhase 2 (Y6-20) AverageLoM (Y1-37...
