Here, the series of finely bedded argyllates and kind of truety sediments.
This really represents the very last phase of the mineralized section of rocks.
So you're getting this build-up of sulfide mineralization on the seafloor.
As that system starts shutting down, you just start getting regular kind of sedimentation
of fine-grained sediments and kind of some chemical exhalative rocks.
But yeah, this pretty much represents the top of the mineralized section, and as you
move down, obviously there's a very stark contrast between the unmineralized rock and
the heavy sulfide content within the massive to semi-mass of sulfide section.
In here, you know, a lot of this is dominated by pyrite, you kind of have to have a bit
of an eye for it, but this is some pretty gaudy mineralization, you kind of tell the
difference between, you know, the color of those two sulfides, this being pyrite, pyrite
dominant here, whereas this is pretty much pure kelko pyrite, kelko pyrite would be
the copper sulfide that, you know, hosts the copper within the deposit.
So growing up, everyone told me that pyrite was called fool's gold.
Yep.
Is it was worthless?
It would look like gold?
Is it still that today, or does it have any value?
The pyrite in itself does host some of the gold mineralization, so I mean there is gold
associated with that.
It's also, you know, the host, you know, in these types of deposits, you have, you know,
you have a lot of sulfur within those hydrothermal fluids, and that sulfur can either, you know,
will attach to iron, and it'll attach to copper, it'll attach to zinc, so I mean all
these deposits are pyrite hosted with, you know, variable quantities of whatever the
ore mineral is, whether it's kelko pyrite, copper, spallyrite, zinc, galenol, lead.
Would you point out the difference between the two pieces of the gan?
Yeah, so this, so this is pyrite dominant.
There is some fine-grain kelko pyrite kind of interstitually throughout there, but this
more gold looking mineral is the kelko pyrite, which is the copper sulphide.
