Cost Comparison

AutoStem vs. Conventional Explosives

Power

AutoStem delivers twice the power than conventional high explosives so less required

Manufacturing

AutoStem production processes are more simplified, greener and less expensive.

Accessories

AutoStem products do not require expensive accessories such as detonators, which also does away with the requirement for strict stock control and inventory of these products.

Transportation

AutoStem does not require special vehicles with security escorts for transportation, and storage is simplified.

q

Safety

Using AutoStem does not require clearing of equipment and personnel for more than 50m and in a mining environment re-entry is immediate.

Storage

Shelf-life of AutoStem is years, so if not used immediately it is not wasted – explosive is months.

Operating Statistics

Autostem cartridges utilised.
A single driller preparing holes, working every second day.
Compressor, rock drill and accessories prices on rental basis.

Total cartridges purchased:
USD 13,862 / EURO 12,182

Machine Costs

Drilling costs:
Compressor rental plus diesel:
USD 51.72 / EURO 45.45per day
Labourer cost:
USD 13.80 / EURO 12.12 per day
Holes drilled per day 70 x – 100 x
Thus drill cost per hole : USD 0.66 / EURO 0.58
Total drill cost per hole x 3,350 holes =
USD 2,211 / EURO 1,943

Costs Per Ton

Total cost of cartridges and drilling:
USD : 13,862 + 2,211 = USD 16,073
EURO: 12,182 + 1,943 = EURO 14,124
Total cost per ton:
USD 16,073 ÷ 10 050 tons = USD 1.60 per ton
EURO 14,111÷ 10 050 tons = EURO 1.41 per ton

TOTAL COST PER TON = USD 1.60 / EURO 1.41

MECHANICAL BREAKER

Operating Statistics

Total number of true operating hours : 540 hours
(Taking into account all: machine downtime, maintenance, part replacements, blasting schedules, miscellaneous)

Equivalent to 67 fully functional days per annum.
Total number of boulders broken = 3,350 (avg. 5o per day)
Tons worked :10,050 ( avg. of 3 tons per cubic meter)

Machine Costs

Purchase cost: USD 103,449 / EURO 90,909
( excluding, moil )( 2,500 hours machine life )
540 hours worked per annum, thus a work rate of USD 41.38 / EURO 36.37 per hour

Maintenance costs: USD 18,931 / EURO 16,637
Operator costs: USD 4,966 / EURO 4,364
Diesel costs: USD 22,180 / EURO 14,491

Costs Per Ton

Total machine cost ÷ tonnage processed:
USD 68,422 ÷ 10,050t = USD 6.81 per ton
EURO 55,129 ÷ 10,050t = EURO 5.49 per ton

TOTAL COST PER TON = USD 6.81 / EURO 5.49
