Ore Reserve Estimation Method

Estimates of the tonnage and average grade of ore deposits (ore-reserve estimates) are made for various purposes They may be made by examining engineers as a basis for placing a value on a mining property in connection with reports on behalf of owners or vendors, on the one hand, or for prospective purchasers or lessees, on the otherTriangular method | Article about triangular method by The ,A method of ore reserve estimation based on the assumption that a linear relationship exists between the grade difference and the distance between all drill holesConventional Methods of Resource / Reserve Estimation ,This course provides comprehensive coverage of the empirical methods of mineral reserve estimation and their application in the contexts of ore estimation, mine planning and grade control The course provides a basis for integrating and balancing these functions so
