Mining trucks

[The Duck]

Did you ever wonder how much actual silver could be in one of those big dump trucks? Here are some numbers - LISA please feel free to correct them.

From Endeavour Silver's website we learn:

"El Cubo, Mexico
Producing

Plant - 1,200 tpd plant rebuilt to 1,600 tpd capacity completed mid-2013.

Grade - 2014 silver grades averaged 105 grams per tonne and gold grades averaged 1.59gram per tonne.

Infrastructure - Approximately 20 minute drive outside of the city of Guanajuato, good road access, power and water plus trained workforce on site.

Land Package - approximately 8,100 hectares (20,124 acres)"

So assume each one of those big dump trucks carry 10 tonnes: 10 x 105gr = 1050 grams [ a kilo ] How do they make money?

"New York Silver Spot Price (24hrs) Jul 18, 2015 at 14:58 EST
Silver Price Per Ounce $ 14.93
Silver Price Per Gram $ 0.48
Silver Price Per Kilo $ 480.01 "

1 kilo of silver would then be .48/gr x 1000grs = $480 per truck load of 10 tonnes.

But OK we really don't know the actual capacity of the truck but we do know this from the Endeavour summary above: 1,600 tpd so 1600tpd x 105gr/t = 168,000gr/day [168 kilos]
so 168,000 x .48 = $80,640/day $564,480/wk [based on 7 day wk] $29,352,960/yr

( based on 1600 tpd that’s - 160 10 tonne truck loads/day - 13/hr on a 12 hr day ) *

I don't think there is much incentive for the truck traffic to decrease soon.
