Mining Costs CAPEX vs. OPEX UndervaluedEquity

In general, underground mining is more expensive than open pit mining as with open pit mining the minerals are found near the surface at a maximum of approximately 200-400 meters depth in bulk tonnage.. The mining costs are estimated in a mining company’s feasibility study which, when available, can be found on the company’s website (often hidden between the news releases).

Opening New Mines

The variable portion of the cost calculation is based on the open pit mining models published by the USGS, which take into account several factors that affect capital expenditures (Camm, 1991). From these, the following calculations were made: The average operating cost per ton ore produced was also calculated using D:

Assume the open pit mining the costs are 275ton of ore OP

Assume the open pit mining the costs are $2.75/ton of ore (OP) and a stripping cost of $1.85/ton of waste (SC). SR = (UG OP)/SC SR = (12.00 –2.75)/1.85 = 5.0 tons of waste/ ton of ore i.e. while the stripping ratio is less than 5.0 it is most profitable to mine the deposit by open pit. When the stripping ratio exceeds 5.0 it will be more profitable to mine the deposit using the underground
