- The Two-Thirty is a polyphase magmatic–hydrothermal breccia complex that hosts Cu–Au (Mo).
- The Two-Thirty is the first significant breccia-hosted mineralisation found in the Northparkes district.
- U–Pb zircon crystallisation ages of the causative intrusion at Two-Thirty pre-date mineralisation at Northparkes.
- Re–Os dates of molybdenite from the Two-Thirty breccia complex are coeval with syn-mineralisation at Northparkes, supporting the model of periodic release of melts and fluids from underlying magma chambers during the formation of porphyry mineralisation in the Northparkes district.
