Mr Sism

You're right about the greater lachlan fold Belt .. it's a big belt and does include BDG with its separate gill reefs.

But it's important not to get BDG's system confused with MCO's and GDR's repetitive vein systems - which have predictability and laddering.

Tectonic forces (sideway earth movements) created cracks in dyke swarms in the case of MCO and GDR - which were filled by gold.
dykes are igneous bodies that host the veins.

As I said read up on the MCO website if you're interested and then ask questions on the excellent MCO forum - everyone isvery helpful - there's some good posters on there.
