Anyone who is interested on doing a little DD.....Here are some things for you to look at that may make you feel better about things:
1. Read the TUD technical report - they DO speak to the metallurgy as well as recoveries using flotation (if memory serves it was ~95% recovery on sulfide ore and in the high 80s overall.)
2. Read about gravity flotation concentration. What you will find is that the process typically concentrates the metals by 70-90 times
3. Read about flotation concentrates and copper smelting processes. What you will find is that these types of concentrates are EASY for copper smelters to treat. I've mentioned this before that the precious metals end up in the slimes during the copper smelting process - no special tweaks needed. Then you collect those slimes (which they will do anyway) and process them for those precious metals. This is something that literally EVERY copper smelter will do as they will not let those metals just go to waste.
Typically agreements will have smelters pay for any gold above ~1g/ton in the concenterate material that they are buying. In a concentrate from this ore it should be many times that even with the grades we have. Does it matter whether it's a copper concentrate or a gold concentrate as long as someone buys the metal? Nope. money is money. If the copper is concentrated that 70-90 times you end up with 35-45% copper in the concentrate. What copper smelter isn't going to buy that? Say just for argument that we only had 0.1 g/ton gold. That still would end up being 7-9 g/tonne in a concentrate. TC ore will more likely to be in the 20-30 g/ton range at a minimum.
Don't believe what anyone says - including myself - without verification. This information is easy to look up. Do it for yourself and you'll feel much better about this investment. Don't let the "mining engineers" of the world disillusion you....
