Sensible valuation of mineral properties has become more critical through the current market cycle. Valuation of mineral properties at the exploration stage is an area where both valuators and users of valuations need to understand the challenges and uncertainties involved. Sorting the wheat from th

The aim is to allow for a rapid assessment of the variability in ore hardness within a mineral deposit with reduced amount of physical breakage tests. This method sees its application primarily in project evaluation phase, where proper evaluation of the variability in ore hardness of the orebody normally requires prolong and costly metallurgical test work program.
The ore also contains 2.8% pyrrhotite, together with several antimony minerals (0.8% berthierite and gudmundite, 0.18% native antimony and stibnite). It
With the mining and processing design in hand and the ore reserves indicated, the actual operating costs of an installation, its likely revenues, overall profitability and operating life can be estimated. The life of a mine is dependent not only on the size of the orebody but also on the rate at which the ore is removed.

These include estimates of mineable ore, pro duction rates, performance of production systems, capital and opera ting costs and the revenue. The financial assessment, set within the
The four key assessment parameters relevant to a mineral right are: depth of mineralization below surface reserve/resource categorization in situ grade and proximity to existing mining or other essential infrastructure. The four parameters are not all-inclusive and other factors such as multi-mineralic occurrences (i.e. multiple
