"Virtually all of the mineralization is hosted in rhyolite."

That is a hard rock sort of similar to granite. I think that most likely the ore is chalcopyrite. Not leachable. But volume of this stuff can pay very well. Porphyries are most often much lower grades.

Morrocco is one of them semi-tropikal terranes with high oxidimation of the cupriferous mineraloids. This makes the deposits amenable to sexy ee-double ewe extracimation. Deposit sizes that could be good would be in the order of as little as 10 million tons.

"Most of the copper-silver mineralization is in the form of chalcocite, a sulfide mineral that is amenable to low cost solution extraction electrowinning (“SXEW”), an acid leach process that produces electrolytic copper without the need for smelting. Additionally, most of the deposit is exposed in the flanks of the hill, meaning that no excavation would be required to expose it for extraction. Additionally, preliminary assessments by Odyssey geologists indicate that there could be significantly more copper and silver in the deposit than estimated by Occidental geologists (a possibility alluded to in their original reports), as well as additional copper in untested areas immediately surrounding the known deposit."

There may be no zinc in it, so I guess Koan will take a pass.
