went out this arvo for a quick look around an area that a person has found alot of gold around years ago. I am not actually sure specifically sure were the gold was found but im within a few kms of the area.

anyways i noticed alot of pink quarts on the surface of the ground and fallen over trees showed a mix of the pink quarts with other brownish looking rocks mixed in it. the other rocks in the ground were black looking pebble and brownish pebbles.

I was just wondering if people have found gold around similar coloured quarts or the other rocks in the ground.

Hi Alexfromdarwin and welcome.
I personnal love this pinkish quartz. Clean white quartz is not anywhere as good to find gold in as "dirty" quartz. What you have there is quartz that is mixed with possibly ironstone (although I may be wrong with this) and that is a fairly good indicator. Hopefully, some gold was also thrown into the mix when it was all being formed. I'd certainly be running a detector over that general area and having my fingers crossed.
Saying all that, I don't want to get your hopes up falsely, that is, it is a good indicator and the area appears good and hopefully gold got put into the mix, but sometimes it just doesn't. Certainly worth a little time anyway.
Goodluck and let us know.
Cheers

Morning Alex,
There is some explanations here in old post;

https://golddetecting.forumotion.net/t1851-indicators-and-quartz-reefs

There are some examples of different quartz species I have detected in this photo. Usually mineral stained quartz contains most gold, however there are always exceptions to the rules.
If you view the walls with binoculars of the super pit in Kalgoorlie you can see where the old timers followed quartz leaders. The old drives show up like fly spots on the massive face, hundreds of kilometres dug many metres under ground.
A little out of reach of our detectors. Wink

the redder the quartz, the better,especially if there is iron stone about.pure white quartz is boring.but you never know,as nightjar said.

Can I ask a (possibly silly) question, is that really generally accepted as 'pink quartz' in your photo Alexfromdarwin?

I by no means have any much idea of what i'm talking about and will be the first to admit it, but the quartz in your photo still looks to be the milky cream colour, clearly there are pink areas of the rock, but I would think cream would be still the domination colour, in most (not all) of those rocks? I would think this might mean the veins of minerals that cause the pink colour (iron/iron oxide?) only became present after the cream quartz had formed and solidified?

I then look at Nightjar's lustrous photo, the pink quartz rock in that photo (to the right of the scales) seems to me to be truly mixed and, pink all the way though. Which i would think would mean the minerals that form the pink colour were present at the time of the quartz forming?

I don't know if any of what I just wrote is right or not, hopefully someone can clear it up for me though.
I think with the saying 'gold is where you find it' any area of interest is worth looking in.

That quartz is heavily fractured, surface solutions or water carrying clays, minerals or iron oxide have entered those cracks and left their deposit, hit the quartz with a hammer and it will most likely break at the fractures and you will see the stuff inside. If their is decomposed pyrite in there I would dolly and pan some.
Iv'e seen plenty of gold in pure white quartz and gold that has formed on pyrite and galena, My theory is gold when formed is a pure element, in later stages iron can come in probably from solutions and coat or form on the gold, could be something to do with ions, molecules, magnetic field, etc which makes them attract, good question for a geophysicist.
cheers
