Gravel mining operation
Gravel mining operation
(OP)
I am doing a geological assessment for a client and have to provide a value for the proposed mining. We have collected the soil boring information and ran the pertinent tests. We have found that there are lenses of gravel that contain approximately 30% gravel, with the remaining 70% meeting the ASTM C33 spec for sand (concrete sand). I have determined that there is approximately 130,000 cubic yards of gravel and 980,000 cubic yards of sand. Does anybody have any idea of what this material would be worth? Specifically, I would like to know what the value of ASTM C33 sand is worth and what the gravel is worth. Thanks.

In some areas, it is necessary to sieve the stuff and re-mix to get proper gradations
Each of the extra steps costs money and should be factored in.
Also, there may be a local market for "bank-run granular material", not requiring any special preparation.
In freezing areas, low P-200 non-frost susceptible material is valuable.

Then there is the cartage costs to get it from the stockpile to the jobsite.
I think you need to talk to a quarry operator.
Another part of the cost is the environmental concerns, you can't just go and dig a big hole anymore.
