Processing Costs on Wheels

[cskhurasu]

Has anyone else noticed the escalation in refractory ore processing cost estimates for TC? They've gone from C$16.50 oer tonne in 2021 to C$38.50 in 2023 to C$48.25 this year in TUD disclosure.

Is that the total cost for processing (would be around $1,450 candian or $1,100 US per oz).  Could probably keep mining costs under $500/oz.  So still workable if the numbers hold true, but tight at current POG. If thats  the total processing cost, while high it is workable.  I assume so but I havent looked yet.

What you neglected to mention is that 2/3 of the metal lies in the CS-600 zone which only has a processing cost of 28.50/Ton

[Jetstream1281]

That zone can produce a 20% Copper concentrate with 25g/t gold just through flotation.

Also, none of these numbers inlcude the High grade breccia system they just found.

[cskhurasu]

According to my handy-dandy mining handbook, you have to have a minimum 24% copper grade concentrate to be saleable to a refinery. 20% doesn't cut it.

Working in the smelting business, I can guarantee you that a 20% copper con with 25 g/t would be saleable......The gold doubles the value of the concentrate....it's the equivalent of having a 50% copper con....

[Larry60]

Of course it would be saleable.  THe question is what would they payout be on the Cu and Au. All this questions are easily answered, although far from definitive, in a simple PEA

[Jetstream1281]

You are also forgetting that there would be dore produced on top of the concentrate....That would be worth many times what the copper concentrate would be....

[cskhurasu]

The 24% requirement for copper in a copper concentrate has nothing to do with the value of the con or the amount of gold. It's a composition requirement due to the chemistry of the refining process. Refineries do not take 20% copper cons. I think TUD will be able to increase to 24% but it will probably mean lower recoveries.

[Jetstream1281]

If you ACTUALLY knkow anything about reifning you'd know that they do in fact take concentrates with 20% copper...Are they ideal? no....but they are still saleable...especially when there is added precious metals and no deletrious elements....Last year copper concentrates averaged 23.5% copper.....Logic would tell you that if there have to be at least as many 20% cons as 25% cons in order to

[Jetstream1281]

I'd also be willing to bet money that by the time a PEA comes out they've upped that number to 25+%
