In-ground value is very different than processed metal, but the general principle is correct. The Sentinel Mine on the other side of the domes region has a 5mt ton deposit and that was 22nd on the original Anglo list of drilling targets. ARCM have the top 7 targets on that list in their licence areas, so them finding something similar is certainly possible.
Extracting that 5m tons will require a large upfront cost and ongoing operational cost. Sentinel was $2.3b up front and employs 6000 people. The mine is valued by the value of the extracted metal minus the cost to extract it, plus a modifier for NPV.
NPV, or net present value, takes into account the value of the upfront money if you put it into an investment instead. For example, if you invested a billion dollar at 8% compound interest, then in 5 years you would have almost $1.5b. So if you want to use that money for building a mine instead, you treat the $1b as $1.5b when calculating metal value minus cost of extraction.
Having said all that, that is a huge amount of copper so the profit on an NPV basis is still many billions. A tier-1 mine is generally regarded as one with a minimum $2b profit after NPV. ARCM would have 20% of that value, which is $400m or about £320m. In terms of share price that is 26p. Bear in mind, Anglo are hunting for multiple tier-1s and not minimal ones.
All of the extraction cost and NPV calculation applies in the same way for GGP. In fact, its a bigger factor for them as their ore is a lot deeper than expected for Zambia. So the short answer is that if Anglo find what they are looking for (and they are plainly confident given the deal they gave ARCM), you are looking at 10-15x current share price, which is the same conclusion that WH Ireland recently provided in their broker note. Finally, if ARCM hit the same market cap as GGP at its peak (£1.7b), our share price would be £1.38, which would be very nice :)
