Bass Point is an old basalt quarry - near there? You also have Port Kembla and lots of slag nearby, but I am inclined to think your samples are natural. Possibly the spheres are chalcedony, or an iron-rich carbonate mineral.Sydney was supplied by basalt from Kiama-Bombo (fantastic lava colums there) and Bass Point. You might find this interesting....

I didnt at any time think that it was gold inside the lava :) just was very curious what it was..
Mate that place is amazing.
I explored it a little today sooo many differant types of lava stones and crystals there.. i brought maybe 50 home.
Also went and collected many more lava rocks with and without and with varying amounts of metalic interferance.
Am half asleep now are you from sydney region yourself? Seems there is plenty of value in lava rocks alone
 
I also find them fascinating, and have visited many active volcanoes and hot springs around the world (eg Vesuvius, Mt St Helens, Agung, Toba, Merapi, Bandung, Ngaurhoe-Ruapehu-Tongariro, Taranaki, Kilauea, and a lot through Nevada-California-Colorado).
 
I found a few larva rocks while surfing around Sumbawa in Indonesia. Local guy there was cooking fish on some. Smelt good too!
 
@goldierocks thats awesome mate you sound well travelled..
But i am happy that at least you never found my metalic balls in any of your explorations ;p
@surfer dude. I tried surfing once and had dolphins swim along side me.
I thought 1 was a shark at 1st and got scared.
Changed my surfboard forna speargun.
I decided if i was going to risk getting eaten alive i was going down with fight.
I used to love spearfishing alot..
Buy 3 kida in the last 5 years i had to put that hobbybon hold and take up family/kid friendly hobbies..
And now am playing with rocks
 
I won't take up Goldies thread with chitchat , but Goldie is our own version of Dr Karl.
And I have also surfed down around the Gong and seen the stones but never worried about them.
If you love rocks and formations , and if you're ever down the south coast Try taking a look down around south Durras, the Sydney basin finishes there and the formations in the rocks are amazing.

Can anyone help me identify this? It was found in a known gold area. With lots of quartz too
 
Lukep said:
Is it common to the area?
Looks like sedimentary rock like sandstone or chert to me but hard to tell.
Country rock or rock native to the area.
Is the second photo showing quartz through the rock? If so then you've probably found an area where igneous rock (in this case quartz) has intruded the country rock. These contact zones can be good gold areas.
Maybe crush a sample & pan to see if gold is present.
 
Hey Goldierocks, that is one sweet shot of Bombo Quarry which now is a photographers haven but in my day it was a place to ride motorbikes . How things change.

I went back today and found more of this type of rock, there is mine shafts there. There is no info on the area... lots of quartz
