Kalgoorlie in the context of "Mineral exploration"

Mining engineering is the extraction of minerals from the ground. It is associated with many other disciplines, such as mineral processing, exploration, excavation, geology, metallurgy, geotechnical engineering and surveying. A mining engineer may manage any phase of mining operations, from exploration and discovery of the mineral resources, through feasibility study, mine design, development of plans, production and operations to mine closure.

Gold mining is the extraction of gold by mining.

Historically, gold mining from alluvial deposits used manual separation processes, such as gold panning. The expansion of gold mining to ores that are below the surface has led to more complex extraction processes such as pit mining and gold cyanidation. In the 20th and 21st centuries, large corporations produce the vast majority of the gold mined. However, as a result of the increasing value of gold, there are also millions of small, artisanal miners in many parts of the Global South.

The South West Land Division is one of five Land Divisions of Western Australia, a part of the cadastral divisions of Western Australia. It includes the cities of Perth, Albany, Bunbury, Busselton, Geraldton, and Mandurah. It also includes the regions of South West, Great Southern, Peel, most of the Wheatbelt, and the coastal areas of the Mid West.

The population of the division is about 2.2 million people, with 1.8 million living in the state capital, Perth, and a further 400,000 people living in the surrounding regional cities and rural areas. This leaves approx. 200,000 people living in the remainder of the state, most of them residing in the regional centres of Broome, Esperance, Kalgoorlie–Boulder, Karratha, and Port Hedland. Therefore, around 92% of Western Australia's population lives in this division.

A multiple-unit train (or multiple unit (MU)) is a self-propelled train composed of one or more carriages joined, and where one or more of the carriages have the means of propulsion built in. By contrast, a locomotive-hauled train has all of the carriages unpowered.

An implication of this is that all the powered carriages needs to be controllable by a single engineer or driver, which is a case of the broader concept of multiple-unit train control. In other words, all "multiple units" employ some variation of multiple-unit train control. In the broader context "unit" means any powered rail vehicle, including locomotives (that does not carry cargo) and powered cargo-carrying carriages. In the context of this article, "unit" refers specifically to the latter only (whether the cargo is passengers or some other cargo).

The Cocos Malays are the majority ethnic group of the Cocos (Keeling) Islands territory of Australia. Today, many of the Cocos Malays can be found in the eastern coast of Sabah, Malaysia, because of diaspora originating from the 1950s during the British colonial period. There are also established diaspora communities in Western Australia, particularly in Broome, Geraldton, Kalgoorlie, Katanning, Perth and Port Hedland.

Despite that they all have assimilated into the ethnic Malay culture, they are named in reference to the Malay race, originating from different places of the Malay Archipelago such as Bali, Bima, Celebes, Madura, Sumbawa, Timor, Sumatra, Pasir-Kutai, Malacca, Penang, Batavia, and Cirebon, as well as South Africa and New Guinea.
