Giga Metals Corp. (TSXV:GIGA) has released analytical results from 15 holes drilled in 2021 on the company’s Turnagain Nickel/Cobalt Project in British Columbia, Canada.
The 2021 work programme included:
- Nine NQ resource infill holes totalling 4,214 metres within the Horsetrail and Northwest zones of the Turnagain deposit.
- Six HQ geotechnical holes totalling 2,082 metres sited on the margins of Horsetrail and Northwest zones of the Turnagain deposit to support pit engineering design.
- Seismic refraction survey in Flat Creek Valley in support of tailings management engineering design.
“The infill drilling is focussed on later years in the mine life, at the edges of the pit design in our 2021 PEA,” said CEO, Mark Jarvis.
“The drilling was designed to allow for conversion of resources from the Inferred to the Indicated category, and we have not seen any surprises.
“The geotechnical holes within the proposed ultimate pit provided valuable geotechnical information and, where ultramafic rocks were intersected, are expected to move some Indicated resources to the Measured category. Additionally, the Company now has acquired valuable geotechnical and hydrogeological data with which to advance the project engineering.”
Resource Infill Drilling Programme
The infill drilling programme was conducted with one skid-mounted drill rig in the Horsetrail and Northwest zones in areas of Inferred resources. Drill core samples were one-half NQ core.
Geotechnical Drilling Programme
The geotechnical drilling programme was conducted with one skid-mounted drill rig in the Horsetrail and Northwest zones. Although these drill holes provide valuable additional geological and resource modelling information, their primary purpose was to investigate the geotechnical characteristics of the proposed pit wall areas with oriented core and optical televiewer, and to conduct hydraulic conductivity packer tests and install vibrating wire piezometers to guide engineering design. Where ultramafic rocks were intersected drill core samples from this program were one-half HQ core.
Seismic Refraction Survey
The seismic refraction survey was conducted by Frontier Geosciences from September 7, 2021 to October 6, 2021 in support of engineering design for the proposed Turnagain Mine tailings storage facility and had three main objectives: to estimate overburden thickness, to estimate overburden characteristics, and to estimate depth to water table.
Information gathered will be used to select sites for sonic and diamond drilling to further characterise geotechnical characteristics for tailings storage design.
