RE:TAKEOVER: Second editionYou may want to save a few days and look no further than the Orezone website for a guidepost, ie a very recent example of how it's done and valuation metrics for these million ounce plus reserve deposits.
Review ORE's 2019 Feasability Study Update :
https://orezone.com/site/assets/files/5429/2019-06-26_nr_ore_xconi8esfh8.pdf Table 3 page 4 Mineral Reserve Estimate and you will see that it will be just like Kobada in terms of a minimum 100,000 plus ounce per annum producer from the soft rock OXIDES (and its all about the free-dig soft rock oxides) during the first 10 years.
The balance of ORE's ounces will come from the more expensive, deeper and Phase 2 upgraded (and not yet funded) plant to produce ore from the harder rock sulphides, which AGG's recent press releases refer to it being able to as well, but won't need to for quite a while as the main Kobabda sheer (forget about Gosso for the moment) remains open for further soft rock oxide ounces at length and depth, so say the AGG PR's.
And that's the problem with dinky 50,000 ounce per annum producers like RBX, no matter how profitable it may be over a couple of year period, it's not in any position to add monster reserve ounces, other than through M&A, to get receive a sustainable valuation.
Study the ORE valuation numbers carefully and pay close attention to the difference between oxide ounces and sulphide ounces in the ORE deposit.
