The CIM Estimation Best Practice Guidelines Committee was formed to develop Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines.
The General Guidelines document was produced and approved by CIM Council on November 23, 2003. The original committee has not completed further work since that time; however, sub-committees have been established from time to time, to prepare commodity-specific guidelines.
Currently, 2 sub-committees are active:
- Following a request from the Ontario Securities Commission, a sub-committee was established to prepare guidelines for the estimation of Mineral Resources and Mineral Reserves for lithium brine deposits
- Members of the original sub-committee for potash are no longer satisfied with the current potash document. A sub-committee has been established to review and re-write the guidelines
