Hey anyone help me out with this rock I found in river its quartz has blues pieces in it not sure what they are and looks like small specs of gold on outside and maybe bigger bits inside any information or guidance would be appreciated thanks.

Not sure, maybe tin or pyrites crystals ? Dig a bit out and see if its crunchy or magnetic.

Ok thanks I will try that, so yes the black blue coloured bits are magnetic and they crunch apart

Magnetite iron ore possibly.
