In October 2021 the Mount Gibson announced a staged suspension of operations to preserve the value of the Shine deposit and provide time to assess the iron ore market outlook. The suspension of operations was due to the significant iron ore price decline, product discounting and increased shipping, and subsequent care and maintenance costs. |

Gindalbie are the vendors of the project to Mount Gibson. The Shine Project area is defined by an area previously agreed between the tenement holder “Minjar Gold” and the vendors Gindalbie who have iron mineral rights over the tenure. The Shine Project Area is over parts of 3 mining leases M59/406, M59/421 and M59/731.
7 March 2014 - Mount Gibson Iron Limited (Mount Gibson) advises it has completed the acquisition of the advanced Shine hematite iron project from Gindalbie Metals Ltd (Gindalbie).

Summary:
The Shine Hematite deposit is located within the Warriedar Fold Belt which is part of the Archaean YalgooSingleton greenstone belt. The deposit is located along a north-northwest trending, sub-vertical 50 – 120 m wide banded iron formation (BIF) of the Windanning Formation which is part of the Luke Creek Group. The BIF forms a prominent ridge which is approximately 50 m to 90 m wide in the Shine area. A sequence of mafic, ultramafic and pelitic sediments bounds the BIF to the east while a talc-rich ultramafic schist dominates west of the BIF. Where the BIF does not outcrop it is covered by laterititic or colluvial material. The iron mineralisation (goethite, hematite and magnetite) is strata bound occurring only within the BIF unit.
The host Banded Iron Formation of the Shine iron mineralisation is sub-vertical and dips to the west at approximately -85o. Holes are predominately drilled at an inclination of -55° and -60° towards both west and east due to the sub-vertical nature of the hosting unit.
The Shine deposit is hosted within a north-south trending BIF. The mineralisation parallels the stratigraphy, trends roughly north-south and is sub-vertical, with a total strike length of about 1.7 km. The mineralisation occurs mainly in two sub-parallel zones which are up to 30 m wide in places.
Summary:
It is assumed the deposit will be mined using open cut methods.
Typical small scale open pit mining methods are appropriate for the deposit. The inter-ramp slope angles are 47° with batter heights of 20m and face angles of 60°. Berm widths are 8m. A 0.5m dilution skin has been applied to the mining model to reflect dilution.
A minimum mining width of 20m is used. The Project assumes road haulage from the mine to the port in Geraldton (300km). The Project is dependent on an existing port facility.
Clearing of the Shine open pit footprint was completed in February followed by the commencement of blasting and mining of overburden in late March 2021. First ore was mined and stockpiled in early April. Total material movement amounted to 1.9 Mwmt since the commencement of mining, including approximately 55,000 wmt of sales-grade ore.

Reserves at June 30, 2022:
Shine hematite and magnetite Mineral Resources are roperted at 50% Fe cut-off grade.
The Shine project in the Mid-West retains its Mineral Resource Estimate (15.1Mt at 58.2% Fe), with the Ore Reserve removed given the project’s current care and maintenance status.
