Report Recommendations

The Report provides several recommendations based on work completed to date by the Company and its various contractors and consultants. The premise underlying the recommendations is that a Preliminary Feasibility Study (PFS) for the Plymouth deposit based on the 2023 MRE should be undertaken as the next stage of its technical and economic evaluation. The Report recommends that this be carried out as a two-Phase program, the first of which predominantly consists of identifying and assembling all technical, economic, and other information required to support preparation of the PFS. Phase II would be first focused on assembling, analyzing and interpreting Phase I results and acquiring additional data where necessary. This would be followed by completion of the detailed PFS evaluation of project viability and preparation of an NI 43-101 Technical Report that documents all contributing work programs and results.

Qualified Persons

The Report, including the 2023 MRE, was prepared by Matthew Harrington, P. Geo., Michael Cullen, P. Geo., and Kevin-Dane MacRae, P. Geo.
