What are good metal grades?

[prawn_86]

Hi all,
A question that could be beneficial to all the newbies out there like myself.

What are good/acceptable/feasible grades and depths for all the major mtals out there?

A link or some basic data would be much appreciated.

And obviously it depends on the amt of other metals present, but im just after a very basic guide.

thanks in advance

Theres already some discussion about this on another thread.
Try to search it.

YT did an excellent post i remember.

Well ill make a start anyway.

Uranium: 300ppm
Copper: 1%
Zinc: 3%

i did this when i first started also. i thought it was as simple as getting grades then comparing companies.

However there are to many things to compare

a lot of variables:

- depth of resource
- size of resource
- type of mine that would be feasible
- price of metals
- forecast demand of metals
- recovery rate
- production design

i would suggest a book by victor rudenno the mining valuation handbook, very good and explains quite a few things

YT's post was -

Hi there,

I'm no expert, I can only offer my opinion on the following commodities

Uranium 0.05% or above, but with increasing prices 0.03% will soon be viable

Iron Ore 60%+ Fe (With low impurities)

Nickel 1%+

Gold 2-3g/t Minimum

Zinc 5% +

Copper Really 2%+

But it all depends on commodity price, as prices increase it becomes economic to mine lower and lower grade ore,


Other important factors are

- Proximity to infrastructure (The closer the better, with Toll Treating the best!)

- Impurities in the deposit soil (Less impurities = less chemical benefication required)

- Major JV or funding backed by Insto? (Very important as most projects can cost between $50- $250m in CAP EX)

- Depth (Always favour Open Pit)

Hope this helps
