Ann: Nifty Copper Project Restart Financing Update, page-274

How much more infrastructure is needed to build an underground mine vs an open pit? Alot more, is the answer and that's why it's alot more expensive.

At no time in the history of Cym has Barry ever said they were going to restart underground mining.

Well why can't you just run oxides through the concentrator? Because oxides have a lower % of copper then sulphides which means you would need to feed way more dirt most likely making it uneconomical and why no other companies bothered to do it.

Heap leaching isn't the issue, how much copper is in the ground isn't the issue.

The issue is why haven't the financiers gotten excited about the project? IMO I don't think the technicals like heap leaching or resource size are what's raising their red flags.
