The Report was authored by independent Qualified Person Kenneth Wheatley, P. Geo., M.Sc., of Rock U Consulting. The Report is available on SEDAR+ at www.sedarplus.ca and is published on Greenridge’s website at www.greenridge-exploration.com.
Statement of Qualified Person
All scientific and technical information contained in the Report summarizing the work completed to date on the Project has been reviewed and approved by Kenneth Wheatley, P.Geo, M.Sc., an independent Qualified Person (“QP”) under the definitions established by NI 43-101. The Report does not contain a Mineral Resource Estimate (“MRE”) in accordance with NI 43-101.
The QP has reviewed and verified that the technical information with respect to all the Company’s exploration efforts to date contained in the Report are accurate and has approved the written disclosure of such information. The Report is intended to be read as a whole, and sections should not be read or relied upon out of context.
Key Technical Report Recommendations
Further work on the Project is recommended in the area of the Cable Bay Shear Zone (the “CBSZ”), a prominent crustal-scale geological structure trending northeast-southwest through the Project that is largely underexplored for uranium deposits. The CBSZ is characterized by a well-defined conductive signature, radiometric anomalies, and numerous historically-mapped uranium occurrences. A ground gravity survey to better define future drill targets is recommended over the CBSZ extending at least five hundred (500) metres of either side of the historical electromagnetic conductors.
