The Constance Range project is located 180kms northwest of Mount Isa in Queensland.
In 1957 BHP procured an exploration lease over the large Iron formation known as the Constance Range in the Lawn Hill Block in Northern Queensland. The style of mineralisation has been described as Clinton type oolitic ironstones.
BHP carried out an intense exploration and drilling program in 1958. A pre-feasibility study completed in 1963 recommended development. Subsequently the Hamersley Ranges in Western Australia became the main iron project for BHP and development of the Constance Range area ceased.
Strategy
Our strategy is to initially develop a data base of all the work previously carried out on the Company's tenements. A comprehensive drilling program is planned to endeavour to establish JORC compliant resource and reserve estimates.
About Iron Ore
Iron ore is the raw material used to make pig iron, the key ingredient in the production of steel, one of the most important and enduring products in the world today. 98% of mined iron ore is used to make steel.
Iron is a mineral, forming naturally over geological periods in the ground and within rocks. It is one of the most common elements on earth, comprising about 5 per cent of the earth's crust. Rocks containing iron ore often date to more than 2,500 million years old.
End Uses
Steel is the most common form of iron. It contains about 1 per cent carbon and has properties that make it an excellent material for thousands of different uses.
- Stainless steel contains chromium, making it highly resistant to rusting. It is ideal for use in motor vehicle parts, food preparation tools, utensils and hospital equipment.
- Tool steel is extremely hard, and is used in metalworking tools. It is produced by tempering certain types of steels by putting them through quick heating and cooling cycles.
- Cast iron is a partly refined iron that contains up to 5 per cent carbon, making it very hard, but brittle. These properties make it ideal for moulded parts, like car engine blocks.
- Wrought iron is nearly pure iron mixed with a glasslike material. It is rust resistant and softer than cast iron, making it ideal for use in outdoor furniture, porch railings and other decorations.
