Ann: Desktop Studies Significantly Increases the Korbel Prospect, page-25

I posted this example in another thread:


0.43 grams = 0.0151678 ounces per tonne

0.0151678 ounces x 76% recovery = 0.0115 ounces

0.0115 ounces x USD $1580 = USD $18.21 per tonne of rock

Using a 100 tonne capacity mining truck ( keeps numbers simple )

100 tonnes x USD $18.21 = USD $1,821 revenue per truckload of payable ore

Assume 50% of rock is waste for for every 1 truck of payable ore you have 1 truck of waste

That means USD $911 for every truckload of material moved (whether it be waste or ore ).

Remember also the processing is simple. Stack on a heap leach pad and run leachant through it. The resulting solution gets processed to extract the gold.
