As part of SRK’s engagement and the ongoing development of the project, SRK reviewed the inferred gold resource estimate prepared by Coffey Mining Pty Ltd (“Coffey”), which was set out in their NI 43-101-compliant technical report dated effective November 23, 2012 and filed on SEDAR on March 14, 2013. In the process, SRK identified issues with respect to certain estimation methodologies employed by Coffey which SRK believes materially overstate grade and contained ounces.
Mine Development Associates (“MDA”) was subsequently engaged by Columbus Gold in an effort to resolve the differences in the methodologies used by Coffey and those considered appropriate by SRK, both internationally respected and recognized independent mining consultancies. MDA’s conclusion supports SRK’s recommended methodology.
In the interest of providing timely public disclosure, Columbus Gold has not yet had the opportunity to obtain comment from Coffey on their choice of methodologies used in their resource estimate.
