Exploration & Growth

Millennium’s 100%-owned land-holding at the Nullagine Project covers 264km2 of the highly prospective and under-explored Mosquito Creek Gold Belt.

The Company has a three-pronged plan to unlock the regional potential within this highly prospective area to deliver a significant step change in production and mine life at Nullagine, aimed at establishing a +5 year mine life based on annual production of +100,000 ozpa.

Sulphide Ore

The Nullagine Project hosts a significant Mineral Resource contained in sulphide ore, which was previously thought to be untreatable through the existing Nullagine processing facility.

However, recent studies have delivered a major breakthrough, showing that portions of the sulphide ore can be processed through the addition of a small modular concentrating circuit to the tail-end of the existing CIL plant.

This method is well understood and has been used successfully for many years to maximise the recovery of processed sulphide ore at other major WA gold mines including Granny Smith and KCGM in Kalgoorlie.

Capital requirements for the sulphide plant expansion have been estimated at A$12-15 million. First project orders have been placed for long-lead, critical path processing equipment, and commissioning of the upgraded plant is on-track for Q1 2019.

Underground Potential

Scope also exists for a substantial increase in the Mineral Resource base at Nullagine, with extensive mineralisation identified beneath all known Resource areas.

Of the 30 deep targets identified at Nullagine, only four have been tested to date – all delivering highly encouraging results.

Development of Millennium’s first underground mine at Bartons is currently well advanced, with first high-grade development ore delivered in July 2018 and first high-grade stop- ing ore scheduled for Q1 2019.

Underground studies are underway on several additional deposits, with drilling continuing to test the Nullagine Project’s broader depth potential.

Oxide Exploration

Oxide ore has been the foundation of the Nullagine mining operation to date, and oxide exploration will continue to remain a key focus.

Exploration drilling aimed at growing the Nullagine gold inventory and mine life continues to deliver thick, high-grade intersections across multiple prospects.
