7.0 Mine Operating Cost Estimation

For feasibility studies, mine operating costs are typically developed by miningfunction (drilling, blasting, loading, hauling, roads and dumps, general mine,general maintenance, and mine administration) with each function defined in termsof operating labor, maintenance labor, and repair parts and consumables. Costsare developed by mining period from equipment levels derived as a function of total

material mining rates. The mine production schedule and equipment requirementsfor use in this exercise are summarized in Table 7-1.

Salaried manpower levels and cost by mining period are developed in Table 7-2.The annual salaries shown are typical western-US rates and include a 45 percentburden. Supervisory and technical manpower levels may vary significantly fromproperty to property, reflecting both corporate philosophy and complexity ofoperations.

Hourly labor requirements and costs are calculated in Table 7-3. Labor ratesshown are again typical western-US. Manpower levels for major equipment arecalculated from the average number of units operating during each period, whichare included in Table 7-1, multiplied by the number of crews required and anallowance for vacation, sick leave, and absenteeism (VSA) plus the degree ofcross-training. VSA coverage usually requires a 7-8 percent increase in manpowerand the adjustment has been brought up to 10 percent to consider a significant

degree of cross-training (a lesser degree of cross-training would require a higherfactor).

The number of mechanics required for each mining period is a function of thehourly maintenance labor cost for each piece of equipment and is calculated inTable 7-6 and brought back to this table. Historically, each type of equipment hadits own distribution of mechanics, welders, and electricians. With the maintenancefunction increasingly becoming one of component exchange, rather than

specialization, a generic mechanic is used to simplify calculations.

Manning levels for non-equipment areas (Trainees, laborers, pumpmen, lubemen,tiremen, utilitymen, etc.) are a function of local conditions and operating practice.

The costs calculated in Table 7-3 are used to develop operating labor costs by

Maintenance labor costs are calculated by mining function in Table 7-6. Summingall the equipment-generated labor costs and dividing that total by the period cost for

one mechanic calculates the number of mechanics required for each period. Thiscalculated number of mechanics is adjusted by the VSA and cross training factordeveloped in Table 7-3 to arrive at the total mechanics required. The cost of thetotal number of mechanics is greater that that required by the itemized equipment,due to rounding up to whole numbers, and the difference is allocated GeneralMaintenance to cover small vehicle maintenance.

Costs for explosives are developed in Table 7-7.

In Table 7-8, functional costs for repair parts and other consumables are derived ona functional basis. An allowance of $0.03 per ton has been added to the GeneralMine costs to cover miscellaneous supplies. To account for gasoline and smallvehicle maintenance/supplies, an allowance of $0.04 per ton is added to GeneralMaintenance. An additional $0.05 per ton has been included in Mine Administrationto cover a dispatch system, surveying and mine computer hardware/software, andother similar items.

Table 7-9 summarizes mine operating costs both by mining function and by majorcost center.

Table 7-10 summarizes diesel fuel and prill consumption by mining period and theresults are used to size storage facilities (tank farm and prill silos).

Table 7-11 summarizes mine capital costs by mining period in terms ofpreproduction stripping, mine equipment, and mine facilities.

Table 7-12 summarizes mine production, equipment, manpower, operating costs,equipment capital, facilities capital, and the preproduction stripping cost by miningperiod.
