In Canada, National Instrument 43-101 requires reports containing estimates of mineral resources and reserves to be prepared by, or under the supervision of, a Qualified Person (QP) who has at least five years of experience with the reported minerals and is a member of a professional association.
 The QP accepts personal liability for the professional quality of the report and underlying work.

The rules and guidelines codified in National Instrument 43-101 were introduced after a scandal in 1997 where Bre-X geologists salted drill core samples at a gold exploration property in Busang, Indonesia.
The falsified drilling results misled Bre-X investors and upon discovery of the fraud, the company collapsed in the largest gold mining scam in history.
