Iron Ore Projects

Iron Ore Project Details

The Iron Ore Projects are located on mining tenements covering approximately 62km2 located 175 km northwest of Kalgoorlie in Western Australia.

The Iron Ore Projects are situated in the Yilgarn Region of south-western, Western Australia.  The Yilgarn Region is a host to many significant mineral deposits that have been or are being mined for iron ore. The tenements cover the Yeriligee greenstone belt which is some 80 km in length and lies within the Southern Cross Province of the Yilgarn.

The Iron Ore Projects, comprises of three distinct mineral projects:

1.     The Ularring Hematite Project: comprising hematite material (“hematite”), to be marketed as potential direct shipping and/or beneficiated iron ore; 

2.     The Moonshine Magnetite Project: comprising magnetite resources (“magnetite”), to be marketed as a beneficiated magnetite concentrate; and

3.     The Treppo Grande Project:  comprising hematite material (“hematite”), to be marketed as potential direct shipping and/or beneficiated iron ore. 

Given considerable investment has been made to date in defining a resource and understanding the technical aspects of the Ularring Hematite Project, MIO’s focus will be on obtaining a partner to fund the development as well as continuing negotiations with existing producers to gain access to rail and port infrastructure that will provide Macarthur with an export avenue.

In addition, Macarthur will continue to explore options for simplified ore processing and options to blend higher grade material with existing producers in the region.

Ularring Hematite Project

Mineral Resource consisting of Indicated 54.46 Mt @ 47.2% Fe and Inferred 25.99Mt @ 45.4% Fe

The Ularring Hematite Project’s Mineral Resource consisting of Indicated 54.46 Mt @ 47.2% Fe and Inferred 25.99Mt @ 45.4% Fe, was previously announced on August 16, 2012 (NI 43-101 Technical Report filed October 1, 2012, titled “NI 43-101 Technical Report, Macarthur Minerals Limited, Pre-Feasibility Study, Ularring Hematite Project, Western Australia”).

Environmental Approvals

The Company has received approval to develop an iron ore mine for the Ularring Hematite Project and associated infrastructure at the project location under the Environmental Protection Act 1986 (“EP Act”) and the Environmental and Biodiversity Conservation Act 1999 (“EPBC Act”). A number of ongoing compliance conditions are imposed with the approval. The Ularring Hematite Project is well placed to fulfil these conditions that it has developed.

Copies of each of the referral documents, relevant supporting information and decision notifications have been made publicly available at the following links:

  1.  Department of Environment Assessment
  2.  Environmental Protection Authority Assessment
  3. Technical Reports One | Technical Reports Two

A number of other regulatory approvals are yet to be sought but will also be made publicly available on this website where appropriate.

Copies of environmental compliance documents are available here.

Moonshine Magnetite Project

Inferred Mineral Resource consisting of 1,316 Mt @ 30.1% Fe.

The Inferred Mineral Resource estimate for the Moonshine Magnetite Project was initially prepared by CSA Global Pty Ltd (NI43-101 Technical Report filed  December 17, 2009, titled “NI43-101 Technical Report on Lake Giles Iron Ore Project: Western Australia”) and was updated by Snowden Mining Industry Consultants (NI43-101 Technical Report filed March 25, 2011, titled “Macarthur Minerals Limited: Moonshine and Moonshine North Prospects, Lake Giles Iron Project, Western Australia, NI43-101 Technical Report – Preliminary Assessment”). The Moonshine Magnetite Project has an Inferred Mineral Resource consisting of approximately 1,316 Mt @ 30.1% Fe. 

A Preliminary Assessment Report was prepared on the Moonshine Magnetite Project by Snowden Mining Industry Consultants in 2011.

Treppo Grande Iron Ore Project

The Treppo Grande Project covers an area of 68 km2 and is located approximately 32 km west of the MIO Projects.

The Treppo Grande Project covers an area of 68 km2 and is located approximately 32 km west of the MIO Projects.  The project is also 35km east of current iron ore producer Cliffs’ Asia Pacific Iron Ore Operations and in close proximity to established rail infrastructure to the Port of Esperance. 

This area has been held by a private exploration company wholly owned by renowned Kalgoorlie Prospector Mel Dalla-Costa for the past 8 years under an Exploration Licence (EL77/1208).  During this time, approval was granted for an exploration program of diamond drilling and geophysical mapping. TheTreppo Grande Project has already benefited from flora and fauna baseline surveys indicating the conservation values of Mt Manning are a lower priority than surrounding BIF ridges. In addition, an ethnographical cultural heritage survey by the Traditional owners has cleared the area for sites of significance.

Treppo Grande was explored in recent years for high grade hematite iron ore mineralisation. Exploration by Mel Dalla-Costa identified three potentially economic styles of Direct Shipping Ore (“DSO”) mineralisation including massive dense hematitic ironstones, specular hematite and oxidised ‘Indurated Detrital Ironstone’. A drilling programme consisting of two diamond holes have penetrated the hematitic iron stone at the J-Hook prospect. Significant intercepts include 17.5m @ 65.49% Fe from 2.5m from hole MMS002 and 40.4m @ 55.77% Fe from 3.6 m from hole MMS001. The iron-rich mineralisation (> 55% Fe) is centred on the J-Hook prospect that contains occurrences of massive, fissile and specular hematite.
