Hi Leep
Gold. It ain’t really native to the native planet we call Earth. Most gold arrived on earth roughly around 200million years and 6 days ago in a series of meteor showers. Getting through the atmosphere would have dealt a blow to some of the large chunks. And ended up breaking them into smaller fragments called nuggets.
Anyway, as you can imagine, when an asteroid of IOCG breaks up, and it hits this ole planet at a pace, the gold can end up chunked into a tidy spot, like an IOCG deposit, or can hit at an angle that smashes it all over the place. Anyway, over time, (200million years) this little nugget and his mates get covered by soil, silt, sand, and form sedimentary rocks per se, (dumbing this down for myself, not you). Hitting the planet at pace can mean it’s spread every which way but loose, (classic 80’s Eastwood) and covered by planetary tectonics and erosion etc.
Upshot is that gold can be found in veins, pockets, belting big nuggets or multi- grains, dependent on its arrival trajectory, speed, landing etcetera.
I hope my gcse knowledge of geology (that was done digging out of the grey silted channels of my mind) helps.
I’m digging deep over next two weeks and have revised our mandate to remain overweight here. ;-))
