Good shout for Mindat, I should have searched that immediately (I use it for other things).

Looking at the chemical structure it is a supergene mineral but what makes it unique is that it has zinc without the metals that normally associated with zinc in these deposits. That is an unusual elemental configuration. It seems like a thing you could model but it isn’t surprising that no one has because it wouldn’t have a use in mining.

The places where you would find this ore may not be in places with commercially viable deposit scale as a copper play, especially if it is mostly copper-zinc. The US west is littered with concentrated micro-deposits of diverse copper minerals but no one maps them in a serious way.
