SnapshotThe Kharmagtai is one of the largest undeveloped copper-gold deposits in the world.

The mine design includes open pits at the Stockwork Hill, White Hill, Copper Hill, Zephyr and Golden Eagle deposits. The largest contributors to the mine inventory are the White Hill and Stockwork Hill deposits. The two pits are mined simultaneously and eventually merge into a super pit.

The permitting process for Kharmagtai can be broken down into nine key steps. The permitting process commences at the same time as the updated Environmental Impact Study (EIS), upon completion of the PFS. The steps are well understood and are anticipated to require nine months from commencement to completion.

Summary:

Kharmagtai consists of multiple co-genetic gold-rich porphyry copper centres and tourmaline breccia pipes within the Carboniferous Kharmagtai Igneous Complex.

The Kharmagtai Igneous Complex consists of a series of intrusive bodies ranging between diorite through monzodiorite, quartz-monzodiorite to monzonite and granodiorite compositions.

There are three styles of mineralisation at Kharmagtai; porphyry style stock work Cu-Au mineralisation, tourmaline breccia style Cu-Au mineralisation and epithermal gold associated with carbonate base metal veins.

The deposits at Kharmagtai are atypical in that they are associated with intermediate intrusions of diorite to quartz diorite composition; however, the deposits are in terms of contained gold significant, and similar gold-rich porphyry deposits.

Dimensions
Stockwork Hill: The strike length of the mineralised zone is about 1,350 m. Width is up to 800 m, traced down dip to 1,250 m. Mineralisation outcrops at the surface.

White Hill: The strike length of the mineralised zone is about 1,800 m. Width is up to 830 m, traced down dip to 1,210 m. Mineralisation outcrops at the surface.

Copper Hill: The strike length of the mineralised zone is about 630 m. Width is up to 150 m with apparent plunging to SW at about 40 degrees traced down dip to 420 m dipping 70 degrees to SE. Mineralisation is outcropped at the surface.

Zaraa: The strike length of the mineralised zone is about 1,300m. Width is up to 600m with apparent plunging to SW at about 60 degrees and traced down dip to 1,280m dipping. Mineralisation outcrops at the basement surface, beneath 35m of Palaeozoic cover.

Golden Eagle: The strike length of the mineralised zone is about 400m. Width is up to 400m and traced down dip to 450 m. Mineralisation outcrops at the basement surface, beneath 35m of Palaeozoic cover.

Zephyr: The strike length of the mineralised zone is about 1,030 m. Width is up to 310 m. Traced down dip to 350m. SE. Mineralisation outcrops at the basement surface, beneath 30m of Palaeozoic cover.
