RE:RE:RE:Something to do on a Sunday...The recovery was 86% Au and 64% Cu... give or take a % or two.... The latest MET test work improved recovery to 80% for both, this method added about 1 Billion in profit in the recovery of Cu.
The recovery rate doesnt really matter whether its .50 or .60G/t. All it changes is the size of the rock that needed to be crushed which, as you can see from the video, is as simple as using a different sized crusher to grind the rock down finer before heading to the leach cells. I do not think the MET test indicates that it is going to be more costly at all, but we added a great deal of profit. Anyways, thought I would post the video, interesting for those that didnt know much about it. All IMHO of course.
As for other low grade mining, some in Alaska and some in Nevada, are all very profitable with this type of recovery method as typical Mills cannot be used. You cant reply on profits of other companies but in this case, I will add anyway. Other mines are proving profits of $500-800/Oz. Fuel prices in Alaska and Nevada are way more expensive, as are workers. The tax laws, if similar to what we see in other countries as Ecuador stated, are what will determine profits here. If they are in line with the rest of the world..... with cheap labour (Avg monthly income is about $1,500 for skilled workers), cheap fuel ($1/gallon), roads already constructed.... it's going to be very pretty!
The workers of course will be skilled workers, I.E Drivers, engineers etc... their will be need for none skilled labourers which should be very cheap.
Hydroelectric dams are also going to save us a lot of $$ in the PEA. Leach Feilds type mines, from my DD use about 600-700 Kw/h. Ecuador prices for industry is .06/KwH. Cheap! The U.S is anywhere from .06-.07. (In Nevada)
Ecuador - Electricity: The prices of electricity are US$6.0c/kWh for industry and US$9.5c/kWh for the residential sector (2013). Following strong price rises in the early 2000s, prices are now falling slightly.
All in all, if the tax laws ae similar, with roads already in place, Fuel is going to be less than 1/3 of costs in the U.S, workers are about 1/2 or more less expensive and power is slightly less or the same.
Really looking forward to this PEA...
This is week 4 since Glenn and the Lawyers got it in hand. Monday should be the day... if not hopefully soon!
GLTA and Keep on your DD.
