JWD Project is producing high grade DSO hematite project.
Following improvement in iron ore prices (which are up ~ 50% from when mining activity was suspended) the Company has initiated a restart of mining operations at JWD. |

Summary:
The Wiluna West project extends 45 km in strike over the Joyners Greenstone Belt, near the northern margin of the Yilgarn Craton. The Joyner’s Find Greenstone Belt is a narrow (5 km to 10 km) northsouth striking greenstone belt comprising prominent ridges (in the central and eastern portion) of Banded Iron Formations (BIF) intercalated with mafic and ultramafic schists with minor chert and clastic sediment horizons.
High grade hematite mineralisation occurs within three main BIF ridges (Units A, B and C) with grade occurrences of up to 69% Fe. Iron mineralisation occurs within BIFs surrounded by inter- bedded mafic and ultramafic schist units. Unit B and Unit C have been partially drill tested by GWR for hematite mineralisation. The two main ridges show distinctive mineralisation styles with B ridgeshowing a much lower proportion of remnant bedding and generally a significantly higher portion of haematite especially in the top 20 m. Mineralisation of the B ridge is also much more continuous along strike occurring semi continuously for over 15 km. The mineralisation on the C ridge typically occurs in a series of pods of up to 20 Mt separated by poorly or un-mineralised BIF. The JWD deposit represents part of Unit B.
Summary:
Ore is sourced from the JWD open pit using conventional drill and blast, load and haul methods and trucked to the run-of-mine (ROM) pad for crushing.
