Defense Metals Advances Pre-feasibility Study

Craig Taylor, CEO of Defense Metals, commented:
"It is great to see our technical consulting teams making significant headway with the Wicheeda site investigations. Defence Metals has assembled a world class team of experts who have both the experience and technical skills to bring this project through pre-feasibility."
The SRK geotechnical investigation includes the following scopes:
- Geotechnical engineering (waste rock, tailings, contact water pond, and site infrastructure geotechnical investigation),
- Tailings alternative assessment prior to advancing into PFS-level design of a preferred alternative,
- Geochemical characterization (to support mine planning/waste management and to develop preliminary water chemistry predictions for the main mine facilities).
The work completed to date included field site inspections from SRK personnel: Principial Consultant – Mining Rock Mechanics, Ed Saunders, P.Eng. (waste storage facility geotechnical); Principal Consultant – Geochemistry, Kirsty Ketchum, Ph.D., P.Geo. (metal leaching and acid/alkaline rock drainage geochemical characterization); and Senior Consultant- Mining Rock Mechanics, Aton Bloem (open pit geotechnical).
Site infrastructure geotechnical investigations planned include a series of excavated test pits, and sonic overburden drill holes designed to support the preliminary characterization of the shallow soil subsurface and bedrock foundations of potential future waste rock storage (WSF), mineralization stockpile, contact water pond (CWP), crusher, processing plant (INF), and tailings storage facility (TSF) locations.
To date a total of 13 excavated tests pits and 4 sonic overburden geotechnical holes for a total of 93 metres have been completed to characterize surficial material conditions within the proposed WSF, CWP, and TSF areas (Images 1 and 2). Site geotechnical investigations encountered shallow overburden conditions (nil or <1 metre overburden depth), excavated test pit depths ranging from 1 to 5 metres; and sonic overburden drill holes in areas of thicker surficial material ranging from 7 metre to >36.6 metre depth to bedrock.
SRK on site engineering consultants supervised the investigations and carried out soil geotechnical logging, direct testing, sampling, photography of recovered materials, standpipe installation, and coordination of laboratory testing. SRK will process the data collected from the sonic drilling and test pit investigations, and laboratory testing results will be incorporated into the QA/QC dataset.
In addition to infrastructure geotechnical investigations, SRK has commenced a tailings alternatives assessment prior to advancing into PFS-level design of a preferred alternative. This will include tailings characterization and development of design criteria, a siting evaluation, and an alternatives trade-off.
As part of the geochemical characterization scopes SRK has completed a review and compilation of site geological and geochemical data and drill core logs that have been acquired since the 2021 preliminary economic assessment (PEA). These data will be used to develop a sampling plan of the existing drill core for geochemical characterization of the proposed mine facilities, and future set-up of on-site kinetic leach tests (barrel tests). Data will be interpreted to support mine planning/waste management and to develop preliminary water chemistry predictions for the main mine facilities (source terms). Source terms are an input to the site water and load balance model.
Excavated test pit and sonic overburden drilling is currently paused and is expected to resume as part of the WSF, CWP, INF, and TSF (and TSF alternative) geotechnical investigations during September in conjunction with the planned drilling of an additional four (4) pit geotechnical core holes totalling 820 metres.
