As per above attached, CVV already have some pretty big backers with pretty deep pockets (first link).
In a world where significant copper shortages are being anticipated (second link), and among rising copper prices, i honestly don't think project funding will be a problem.
Also, the $2 billion dollar NPV is pretty much a base case for present value. For each US$0.50/lb increase in copper price above the current copper price of approx US$4.00/lb, the project NPV increases by approx another $1 billion dollars more (as shown in the below screenshot).
If the project is increasingly profitable (as discussed above), then i don't think funding will be a problem (those institutional backers shown above obviously also agree).
An example of funding availability is also shown below. As you can see by the below article, billion dollar copper mining deals are currently happening in today's market (and in much more volatile and risky parts of the world compared to Aus). Quotes from the article shown below the image.
"At least three South African miners are in the running to buy Botswana's Khoemacau copper mine that is home to one of Africa's largest copper deposits, several sources told Reuters, as growing demand for the metal ensures strong competition for the sought-after asset."
"A number of unnamed Chinese investors, are also on the list of companies interested in Khoemacau Copper Mining operations, one of the sources said."
"An increase in copper demand for applications from solar panels to electric cars in coming years has prompted miners to scramble for more supplies of the metal."
"Diversified miner South32 (S32.AX) and Australian rival Sandfire Resources (SFR.AX) dropped out of the race after the first bidding round due to the mine's high valuation, the two sources said."
"The Khoemacau copper mine may be valued at between $1.5 billion and $2 billion, three banking sources added."
Current market cap of CVV is ~85 million (significantly undervalued IMO)
