A Competent Person is …

A mining industry professional

who has a mature ability to reason across the JORC Code*,

can provide a reasoned analysis of the risks in a project

and is able to communicate the material risks (without exclusion)

to their peers, management, the board of directors and investors

(*including all respective items in Table 1)

JORC Code Competence

“Competence requires that the Public Report be based on work that is the responsibility of suitably qualified and experienced persons who are subject to an enforceable professional code of ethics.”

• Minimum 5 years of relevant experience• Member of recognised professional body

• Confident to defend an estimate among peers

I am sufficiently competent to report

under JORC Code Guidelines

Resource Geologists who have conducted fewer than 15 models have not yet developed sufficient requisite JORC Code reasoning levels.

Resource Geologists who have generated estimates on across fewer than 2 commodities not yet developed sufficient requisite JORC Code reasoning levels.

Resource Geologists who have conducted fewer than 5 reconciliations on their own estimates not yet developed sufficient requisite JORC Code reasoning levels.

Resource geologists who do not meet the minimum ‘15-2-5’ criteria, and who do not have at least 10 years’ mining industry experience and at least 5 years’ resource estimation experience, will not have developed sufficient JORC Code reasoning levels.
