St. Charles Erbium Assays Revised
Micrex announces revised results for erbium that were reported for holes 99-04 and 99-06 in the press release dated April 20, 2010. The independent assay lab reports that their erbium results were incorrect due to interference from the sample's matrix elements. The revised assays show trace amounts of erbium are present, and the erbium values they reported previously were in error.
Micrex is encouraged that a proper assay method has been developed to ensure accuracy in the future and to eliminate interference from matrix minerals.
The lab has rerun the tests for all the other rare earths and confirmed that the April results for them were accurate. The average numbers for the rare earths in parts per million (ppm) are:
The full revised assay results can be viewed at the St. Charles page on the Micrex web site at www.mixcorp.com.
Magnetite, titanium, apatite and vanadium already provide a solid foundation for development of the property, and Micrex is confident that the rare earth elements will have a positive, value added impact on the overall deposit at St. Charles.
As a result, Micrex continues to focus its exploration on the Quebec project, with a view of completing a NI 43-101 report and additional drilling.
This press release has been reviewed by Mr. Michael Dufresne, M.Sc., P.Geol. a principal of APEX Geoscience Ltd. and the Company's Qualified Person for this project under the meaning of NI 43-101.
