2005 Annual Report

The theme for this year’s Annual Review is “Taking a Long View”. In the last five years the steel industry has undergone a transformation. Over the period from the 1970s to the early 2000s the industry was characterised by excess capacity leading to an oversupply of steel and suppressed prices. Steel companies around the world had difficulty creating value for shareholders and, as such, were not inspiring investments for the financial markets.

2005 Full Financial Report

The principal activities of the OneSteel Group are mining, steel manufacture, and steel and metal products distribution. Further details are set out on pages 1 to 33 of the Annual Review. There were no significant changes in the nature of the principal activities of the OneSteel Group during the year under review.

Arrium Mining and OneSteel Whyalla Steelworks Environmental And Social Responsibility Report 2012

Welcome to our sixth Environmental and Social Responsibility Report. This report aims to highlight the numerous challenges and successes of the 18-month period from January 2011 to the end of June 2012 in terms of social, environmental and business outcomes. It is part of increasing our transparency and ensuring our key stakeholders – particularly the local community – can keep track of the progress we are making each year.

The launch of this report follows our change of company name to Arrium to reflect we are now a broader mining and materials company. At the local level, this has seen our Mining business become known as Arrium Mining, while the Steelworks has retained its OneSteel Whyalla Steelworks brand.

2012 Sustainability Report

Most readers will be aware that the company changed its name from OneSteel to Arrium effective 2 July this year, following overwhelming support from shareholders at an Extraordinary General Meeting held in May. The change of name reflects that the company is no longer a domestically focused steel manufacturer and distributor, but an international mining and materials company with three key businesses: Arrium Mining, Arrium Mining Consumables and OneSteel Steel & Recycling.

While the year has seen significant change for the company, sustainability continues to be integral to our thinking and the way we do business. Further, our two core values of “safety” and “customer” remain at the forefront of everything we do.

Peculiar Knob Biodiversity Offset Strategy 5 Dec 2012

This is the revised biodiversity offset strategy for project related habitat disturbance at the Peculiar Knob Iron Ore Mining Project.  This project is designed to create an offsite net benefit for the Thick-billed Grasswren at the Nature Foundations Witchelina Reserve. The biodiversity offset strategy consists of two aspects, firstly on ground reduction of predation impacts on the Thick-billed Grasswren due to feral cats and foxes; reduce grazing pressure impacts on Thick-billed Grasswren habitat due to feral goats; and Increase the area and quality of Thick-billed Grasswren Chenopod Shrublands habitat.  The second aspect is a research component, designed to improve knowledge of the biology, distribution and environmental preferences of the Thick-billed Grasswren in Arid South Australia. This program will run for a period of four years in partnership with the Nature Foundation and Flinders University.
