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 operation will commence with an initial plant operating for the first eight years (Stage 1), followed by a capacity expansion (Stage 2) after achieving payback and generating net cash.

Summary:

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

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.

Copper and gold mineralisation is controlled by porphyry phases, oxidation zone, the level of veining, breccia, country rocks and barren dykes.

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 mineralisation is characterised as porphyry copper-gold type. Porphyry copper-gold deposits are formed from magmatic hydrothermal fluids typically associated with felsic intrusive stocks that have deposited metals as sulphides both within the intrusive and the intruded host rocks. Quartz stockwork veining is typically associated with sulphides occurring both within the quartz veinlets and disseminated thought out the wall rock.

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.
