Western Australia
Feldspar is a mineral that is abundantly found in Western Australia. It is an aluminosilicate mineral that contains varying amounts of potassium, sodium, and calcium. Feldspars are the most abundant mineral group, making up about 60% of the Earth's crust. The commercial varieties that are most commonly found are alkali feldspars or sodium-rich feldspars.
In Western Australia, feldspar is predominantly found in the Sinclair Caesium Deposit in Norseman, Dundas Shire. Feldspar deposits are hosted by rocks in the Olary region, which is known for its feldspar and beryl mining. The Olary Province has produced significant amounts of feldspar over the years, with the largest deposit near Antro woolshed, 35 km northwest of Olary, producing approximately 140,000 tonnes of industrial feldspar between 1987 and 2013.
Additionally, Western Australia is home to outcropping areas of Precambrian and early Palaeozoic rocks, which contain pegmatites. Pegmatites are a significant source of feldspar and are found throughout the state. However, the only notable production of feldspar from these deposits has been from the Mount Lofty Ranges.
Feldspar is an important mineral with various industrial applications. It is a crucial source of alumina in glassmaking and the ceramics industry. In ceramics, feldspar acts as a flux and provides the glossy finish often seen in chinaware and ceramic tiles. It is also used in glazes and enamels and is a common filler in paints, plastics, sealants, and adhesives.

Manna Hill
Feldspar is a mineral group that can be found in many locations across Australia. One of these locations is Manna Hill (or Mannahill) in the Olary Province of South Australia. Manna Hill is known for its feldspar production, with irregular feldspar bodies found near Weekeroo Hill, approximately 25 kilometres north-northwest of Manna Hill.
The discovery of feldspar in the Manna Hill region sparked interest in mining activities. In the year 2000, the Manna Hill Mining Co. Pty. Ltd. produced a significant amount of albite, totalling 700 tonnes. Albite is a type of feldspar mineral that is often used in the production of glass, ceramics, and other industrial applications.
The feldspar deposits in the Manna Hill area are associated with a large Mesoproterozoic hornblende-albite amphibolite. This geological formation is located near Weekeroo Hill and is characterised by its albitised margin, which indicates the presence of feldspar. The specific type of feldspar found in this region is known as anorthoclase, an alkali feldspar that contains an excess of sodium over potassium.
The Manna Hill feldspar locality is not the only source of feldspar in Australia. Other notable locations include the Mount Lofty Ranges and the Olary Province in South Australia, as well as various sites in Western Australia, Queensland, and Victoria. However, Manna Hill remains a significant contributor to feldspar production in the country, particularly for the ornamental aggregate known as albite.

Mount Biggenden is located in the North Burnett Region of Queensland, Australia. The area has a rich history of mining, particularly for gold and bismuth. The Biggenden Mine, located on Mount Biggenden, has been operational since at least 1908, as evidenced by photographs from that year depicting the mining area.
The Biggenden Mine is known for its gold and bismuth production, but it is also a source of various other minerals, including feldspar. Feldspar is a common mineral found in many parts of the world, and it is often used in the ceramics and glass industries due to its heat resistance and ability to act as a flux during firing.
In the Mount Biggenden area, feldspar is found in hornblende-feldspar porphyry dykes, which are rock formations that occur when magma cools and solidifies underground. These porphyry dykes can display feldspar phenocrysts, which are large, easily visible crystals of feldspar that can be up to 3mm in size. The specimens of feldspar from this area are typically quite large, with dimensions of at least 75mm.
In addition to feldspar, the Biggenden Mine at Mount Biggenden is known for producing a variety of other minerals, including bismuthinite, arsenopyrite, epidote, and bismutite. These minerals have been exploited or are considered exploitable commodities, indicating the economic significance of the mining activities in the region.
