Hi all,

I have been doing a lot of research on the areas where I am and need help on identifying minerals.

Below are pictures from different sites. If anyone could help I would really appreciate it.

I am wanting t know which areas should I be looking at for possible gold or other minerals of interest/worth.

Also, with the rusty quartz, what is the probability of gold being in it, and if so how to get it out, and would there be placer gold close by on the hill. These areas have not had a detector through them as yet. When I o over these areas I get so many hits it's driving me crazy. So far I have only dug up solid hits and found bullets/shells. I use an X-Terra 705 Gold Pack with DD coil.

Non magnetic rock with dark grey/black sheen.

Dirty rusty quartz from quartz outcrop on top of hill.

Close up of quartz with gold/red sheen.

Rock found on fault with gold coloured specs throughout (may be pyrite?)

Black crystalised sheen on rusty quartz - what is it?

Magnetic hot rock from outcrop on fault line. Looks like gossan.

Igneous rock found on fault.

I have done some crushing but need advise on which ones would be best to crush and best way to do it. I am not an experienced 'panner' or prospector.

Thank you in advance :)

Hi Merry
Pic 1. Not sure.
2. Nice voids & a little Iron, good indicator.
3. Same as 2
4. A bit hard to tell in the pic, looks a little foliated ????
5. This is ironestone / qtz contact.
6. Looks like 5.
7. Does not look like Igneous rock (Granite is igneous) looks like Ironstone qtz matrix maybe on Schist.
 
Hi Lee,

Thank you! I am from south east NSW. Around Canberra.

I presume the contact of the quartz with the ironstone is a good indicator?

And voids, is that the holes within the quartz?

As you can see I am new to this :)

These rocks are spread over around 600 acres.

The rusty quartz from pics 1 and 2 are from an extrusive quartz arenite, siltstone and shale forming distal flysch sequence (still learning what that all means but getting there :) )next to a major fault line. This is from the Ordovican era. I know that there was a gold mine a few kilometres away that have the same geology rock wise according to the geology map.

4 is from a fault line where the above meets with Grey green dacite ignimbrite, limestone and shale lenses, minor rhyolite and andesite. This is from the solarian era. It is from a one of the large rocks that is sticking out of the ground sideways. It is near a cold spring.

Number 6 is from another area and is not quartz, it is magnetic and goes off under the detector. It is on the fault line where tuff and ingnimbrite, feldspathic sandstone and siltstone from the Devonian era meet with the previous mentioned extrusive quartz section, where the rusty quartz is from. I have found quartz veins nearby - some 100 - 150 meters, although thin.

Oops on 7. I was wrong. It is near an intrusive area that is quartz-feldspar porphyry, adamellite, granodiorite.

Hope that all makes some sense, I am learning a lot over the past couple of weeks and basically trying to pinpoint where it is best to search first etc.

Also, I re-posted this in the minerals forum as I think that is where it should be? New to this site and still learning :)
