2017-3-24 · 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 other.
Iron Ore (Fe) is mined in around 50 countries worldwide and used to make steel (buildings, cars, white goods etc.). Global economic growth is the primary factor that drives its supply and demand. When economies are growing, the need for steel in construction increases which drives the price up.
The F3 factor is F1×F2 and enables a comparison of a mine''s (measured by mine) ability to recover the tonnage, grade and metal content estimated in ore reserves.

Traditional methods for ore tonnage and average grade estimation in a single ore deposit can be roughly classified as either geometric or geostatistical (Henley, 2000). In exploration, both of these methods utilize the orebody thickness and the grade over a given thickness (e.g., in drillholes or drifts) located in a grid to estimate the reserve.
Abstract. For the calculation of the volume and the tonnage of ore deposits there is a variety of available methods to choose from, each suited for a particular deposit. These methods fall into two categories: reserve calculation on the basis of cross-sections and on the basis of longitudinal planar sections or level plans respectively.
