Hi GC and welcome to PA mate.
I like your thinking and the ground looks the goods.
Areas with both ironstone and quartz is a good indicator and copper, as a mineral element, proves other forms of mineralization have most likely travelled along with it amongst the foliated path of least resistence.
Crushing samples is a good form of testing the ground but hard yakka....have you tried panning loam samples from the top of the ground to check for color over a wider area?
Keep samples seperate and marked from the specific area from which they were taken.
If there are existing deposits of Au around, the loam will tell you so.
Cheers

Hi, tptal newb and this is my first post but have been reading in the background for a few months, So I went out today to take my newly acquired knowledge of geology (Not much really) to have a hunt. I live in Townsville and as far as I can find no gold has been found here even though the Geo maps I have been looking at says it has a high probability of having it. I found myself what looked from driving past a bit of mineralisation, I took my little hammer and bucket and headed up to the bottom of this hill( Major bitumen quarry is on the other side of this hill and a small one around the corner. Ground looked good at first lots of Iron I found a heap of foliated ground along the rise which I assume pointed to a shear zone. I found a lot of nice little quartz veins , some which were green, I took samples from a fair few places. Closer inspection confirms that I have found small amounts of copper on pretty much every rock in the bucket. Minelab 705 screamed at every one.Waiting on getting some pans to crush and check to see if there is any gold but am happy to have found the right ground first time around. The green veins I'm not sure about, any idea's.
