The revised Mineral Resource estimate incorporates data from the 195 hole, 7,987
metre infill and extension reverse circulation drilling programme completed in
2020. The drilling was in support of Bankable Feasibility Studies with the objective
of extending the nine-year mine life of the Preliminary Feasibility Study (ASX 15
November 2019) by converting substantial amounts of Inferred category resource
to Indicated and Measured, which may then be included in the mine schedule on
completion of the current Bankable Feasibility Study work programmes.
Further breakdowns of the Measured, Indicated and Inferred Mineral Resource
estimate are reported in Tables 4 to 6 in the Appendix for the Total, Weathered
and Fresh Rock mineralisation at a range of NdPr cut-off grades. Data and
estimation criteria used in the estimates are detailed in the Material Information
Summary and in JORC Code (2012) Sections 1, 2 and 3 in the Appendix.
