interactive cloud hosted calculator
This calculator allows the user to take a Resource or Reserve estimate and conceptualizes a potential production scenario. This would include a realistic processing rate and associated annual metal production. The calculator also estimates the insitu rock value and total contained metal.
Mine Production Rate - The white cells are User input cells.
INPUTS
-
Select Metals of Interest from the dropdown list.
-
Input the Resource tonnage and grades.
-
Reserve:Resource Factor: is an estimate of the percentage of the Resource tonnes that convert to Reserves.
-
Grade Dilution Factor: The Resource is normally undiluted, so apply a general dilution factor to the metal grades.
-
RESERVE tonnage and grades: this incorporates the two factors described above,
-
User can modify metal prices.
-
User can modify process recoveries.
OUTPUTS
-
The Insitu Rock Value is based on the metal prices and grades without any recovery or payable factors.
-
Mine Life: is calculated based on Taylor’s Rule, but can be overwritten by the User.
-
Annual and daily processing rates are based on the estimated mine life.
-
Annual metal production is based on the Insitu Metal x % Recovery / Mine Life.
