ABSTRACTIn many cases, mineralization discovered by prior owners of a mineral property may have been considered to be too low grade to be of potential economic interest at that time. Changes in market conditions over time often warrant a review of the economic potential of historical exploration results. Therefore, any available historical geoscientific information can be of great value because it can save the cost and time required to completely replicate the historical data. As qualified persons (QPs) are ultimately responsible for all data used to prepare a mineral resource estimate, they bear the obligation of carrying out appropriate due diligence and validation of all information and historical work prior to their use for estimation. The task of assigning acceptance criteria rests upon the QP. Considering the wide range of possible scenarios, a detailed listing of acceptance criteria is far beyond the scope of this paper. Generally speaking, the acceptance criteria for using historical data will by necessity vary on a case-by-case basis. In all cases, the QPs are encouraged to fully document the criteria used to establish the acceptance criteria. This paper discusses some of the various actions that QPs may consider for validating historical data. |
