Vancouver, British Columbia--(Newsfile Corp. - September 19, 2019) - Mark Jarvis, CEO of Giga Metals Corp. (TSXV: GIGA), announced today that the Company has updated its NI 43-101 mineral resource estimate based on an additional 36 infill drill holes totaling 8,940 metres drilled in 2018 in the areas of the conceptual open pit described in a Preliminary Economic Assessment dated December, 2011 by AMC Consultants of Vancouver, B.C., and by updated geological modeling supported by core logs, rock geochemistry, mapping, alteration modeling and other information.

Open Pit Mineral Resources - Base Case Estimate
|Measured and Indicated||1,073,319||0.220||5,206,056||0.013||312,409|
(1) All mineral resources have been estimated in accordance with Canadian Institute of Mining and Metallurgy and Petroleum ("CIM") definitions, as required under National Instrument 43-101 ("NI 43-101").
(2) Mineral resources are reported in relation to a conceptual pit shell in order to demonstrate reasonable expectation of eventual economic extraction, as required under NI 43-101; mineralization lying outside of these pit shells is not reported as a mineral resource. Mineral resources are not mineral reserves and do not have demonstrated economic viability.
(3) Mineral resources are reported at a cut-off grade of 0.1% Ni. Cut-off grades are based on a price of US $8.50 per pound and a number of operating cost and recovery assumptions, plus a contingency as reported in the December 2011 PEA authored by AMC Consulting.
(4) Inferred mineral resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. However, it is reasonably expected that the majority of Inferred mineral resources could be upgraded to Indicated.
(5) Due to rounding, numbers presented may not add up precisely to the totals provided and percentages my not precisely reflect absolute figures.
"The updated mineral resource estimate for the Turnagain Project represents an important milestone in the path towards advancing the engineering studies of this project," said Mark Jarvis, President and CEO of Giga Metals Corp, "The successful execution of a focused drilling campaign combined with updated geological modeling has resulted in a refined and enhanced mineral resource estimate that, within the first three phases of mining outlined in the 2011 PEA, has confidence levels sufficient to support a Pre-Feasibility study and ultimately a Feasibility study if that is justified."
2019 Updated Mineral Resources comparison to 2011 Mineral Resource
Since the 2011 mineral resource update, Giga Metals has performed infill drilling and also updated its geological modeling. As a result, the Measured plus Indicated resources have grown due to infill drilling, but the Inferred resources have also grown because the volumes of the ultimate conceptual pit have grown. This comparison is provided for information purposes only. This comparison should not be interpreted as a statement of mineral reserves; mineral reserves can only be defined in a Pre-Feasibility or Feasibility study.

For the purpose of advancing engineering studies, the confidence level in enough of the resource has been increased to the Measured plus Indicated categories to support advancing studies to the Pre-Feasibility and Feasibility levels. While the Company believes certain elements of the PEA dated December 2011, authored by AMC Consulting (i.e. the "PEA"), are consistent with the Company's current approach and ongoing evaluation of the project, the PEA can no longer be considered current. The PEA included inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves and here is no certainty that PEA will be realized.
2019 Mineral Resource Classification Methodology
The mineral resource estimates for Turnagain were prepared to industry standards and best practices using commercial mine-modeling and geostatistical software. Garth Kirkham, P.Geo. is the Qualified Person responsible for the Turnagain mineral resource estimates for the purposes of NI 43-101.
Mineral Resources are classified under the categories of Measured, Indicated and Inferred according to Canadian Institute of Mining, Metallurgy and Petroleum (CIM) guidelines. Mineral resource classification was based primarily on drill hole spacing and on continuity of mineralization. Measured resources were defined at Turnagain as blocks with a distance to three drill holes of less than ~40 m to nearest composite and an average of 60 m and occurring within the estimation domains. Indicated resources were defined as those with a distance to three drill holes of less than ~60 m and an average distance of 80 m. Inferred resources were defined as those with an average drill hole spacing of less than ~150 m and meeting additional requirements. Final resource classification shells were manually constructed on sections.
Greg Ross, P.Geo., a Qualified Person as defined by National Instrument 43-101, is responsible for the implementation and supervision of the Turnagain Project QA/QC program. Among other measures, prepared standards and blanks were inserted at the project site, and lab-reported results reviewed, to monitor the quality of the assay data. See reports dated December 5, 2011, titled "Turnagain Project Hard Creek Nickel Corporation Preliminary Economic Assessment"; and dated February 25, 2019, titled "Giga Metals Releases Final Drill Results from 2018 Program" filed on SEDAR for details on geology, mineralization, data verification, sampling procedures, and lab information.
