The Chichester Range trends west-northwest along the northern edge of the Fortescue Valley for approximately 200 kilometers and is known to be underlain predominately by the Marra Mamba Iron Formation. The Chichester Hub deposits are a single, 80 kilometer long deposit, locally dissected by erosion caused by subsequent drainage channels.

Chichester Hub—In the Chichester Range, the Marra Mamba Iron Formation dips less than 5 degrees south and trends west-northwest. In the Christmas Creek area, iron ore outcrops sporadically along with hardcap and detritals. However, further west at Cloudbreak, virtually no iron ore outcrops and surface material is predominately hardcap, unmineralized Nammuldi member rocks and/or detritals.

At the Chichester Hub, the zone of enrichment follows the Nammuldi Member of the Marra Mamba Iron Formation and varies from 5 kilometers to 9 kilometers wide and 80 kilometers long (with a 10 kilometer break where it has been significantly eroded by drainages). Ore grade material can range from about 1 to 25 meters thick with an average approximately 7 meters in thickness. Better mineralized areas average between 8 and 15 meters in thickness. All mineralization dips approximately 2 to 5 degrees south.

Mineralization in the Christmas Creek deposit occurs over an area approximately 39 kilometers along strike and up to 9 kilometers in width, from the surface to a depth of 117 meters. There are four types of mineralization at Christmas Creek: hardcap mineralization, Nammuldi Member mineralization (greater than 50% iron cut-off grade), higher grade Nammuldi Member mineralization (greater than 57% iron cut-off grade) and CID.

Mineralization in the Cloudbreak deposit covers an area approximately 37 kilometers along strike by 5 kilometers in width, from the surface to a depth of 90 meters below surface. Mineralization ranges from 1 to 28 meters thick and is 7 meters thick on average. There are three types of mineralization at Cloudbreak: Nammuldi Member mineralization (50% iron cut-off grade), higher grade Nammuldi Member mineralization (greater than 56% iron cut-off grade) and CID.

The Solomon Hub project mining areas and rail corridor are located on unallocated Crown Land, Native Title claim areas and active pastoral leases (Hamersley, Mt. Florence, Hooley and Mulga Downs). The rail corridor passes through Yandeyarra Aboriginal Reserve to the west of the Great Northern Highway.

The Solomon Hub is comprised of three main sites known as Solomon East, Serenity and the newly discovered Mt MacLeod. Within the Solomon East area, there are two principal areas known as Firetail, and the Valley of the Kings and Valley of the Queens (collectively, the “Kings Project”) that are expected to be developed initially, and a smaller prospective resource area referred to as Sheila Valley.

Throughout the Hamersley Province the Brockman Iron Formation hosts the majority of bedded mineralization, and it is host to some of the largest iron ore mines in the world (Mount Whaleback, Tom Price and Paraburdoo). Geographically, the Firetail deposit is split into two “limbs” of an irregular “V” shape with each limb approximately 7 kilometers in length. Thickness of mineralization units averages around 20 meters, but can extend up to 60 meters in places.

Kings Project—The Kings Project area occupies the majority of the Solomon region, and is 35 kilometers in total length, running in a general east-west direction.

The ore bodies at the Chichester Hub are gently undulating sheets of mineralization which are easily accessible from multiple open pit operations at each location. The position and structure of the iron ore mineralization in the Chichester Range allow for a strip mining process with the ability to backfill mined areas as excavations move along the mine length. The Chichester Hub deposits dip flatly to the south and overburden depth does not exceed 80 meters. The overburden is removed first, followed by hardcap material, then ore.

The thickness of the hardcap, which overlies the ore, is typically between 5 and 7.5 meters. Removing the hardcap involves either “rip and doze” or “drill and blast” methods, depending on the thickness. Once the hardcap mining and overburden removal has progressed into a second and third panel, ore mining is initiated in the first panel. This three panel configuration advances along the strike.

Mining at Solomon Hub occurs at multiple, spatially separate pits, each working multiple faces simultaneously, and hydraulic excavators are employed to dig the material from working mine faces. After the overburden is removed, the iron ore and internal waste are extracted.

In order to maximize the quality of mined iron ore product at Chichester Hub, processing is typically carried out on all ore mined. This is a relatively simple process compared to other commodities, and often only involves a “crush and screen” operation in order to separate the mined material into lump and fines iron ore products.

OPF consists of a separate screen house linked by conveyors to a crushing house, a beneficiation facility (referred to as the “desand” plant) and three large capacity product surge piles which feed a belowground vault that supplies the train loader with product. The crushing, desanding, screening and other ore processing facilities were obtained under a lease agreement.

The mined ROM ore from Solomon Hub is transported to elevated pads (ROM pads) for tipping into a ROM feed bin at a number of separate primary crushing hubs. Two primary crushing hubs, with one for the Firetail Project (for Brockman ore) and one for the Kings Project (with the one for the Kings project comprising two crushing streams for CID and DID ore, and for the Firetail project comprising a single stream for BID ore). The primary crusher system consists of a feed hopper, apron feeder, primary sizer, secondary sizer and product conveyors. The ROM ore is blended at the crushing hubs to ensure a consistent mix of ore in order to achieve the required blend and contaminant levels.

The OPFs are designed to produce a fines product only and would be comprised of a separate screen house with scrubbers and screens linked by conveyors to a crushing house, and a desand plant. The plants are fed by overland conveyors connected to primary crushing hubs. Low grade material is delivered to the desanding unit via a series of screens.
