CDN Resource Laboratories

Assay Standards

CDN Resource Laboratories Ltd. has been preparing site-specific ore assay standards since 1991 and off-the-shelf standards since 1998.

Standards are prepared from appropriate geological materials.
The ore is ground and then screened through a 270 mesh sieve.
The -270 material (<53 micron) is thoroughly blended.
A minimum of 150 sub-samples are sent to Canadian and international
commercial laboratories for round-robin analysis. Statistical work is provided
by Smee & Associates Consulting Ltd.

Please note: certificates for all standards (those currently available as well as those which have been consumed) can be printed from the "Certificates" page.
