Bootu Creek Mine
OM (Manganese) Ltd (“OMM”) owns and operates the Bootu Creek manganese ore mine in Northern Territory, Australia. The Bootu Creek Mine is located 110km north of Tennant Creek in the Northern Territory of Australia, and exported its first shipment of ore in 2006.
Exploration at Bootu Creek commenced in 2001, with drilling completed in 2004 under an early JV structure with GEMCO (the Groote Eylandt Mining Company). Mining commenced at the end of 2005 and the first batch of ore was processed and shipped in 2006. The mine became wholly owned by the Group in 2007.
Bootu Creek is an owner operated mine and is mined conventionally via an open-cut method of mining, blasting, and excavation using hydraulic excavators and dump trucks. The mined ore is crushed, scrubbed, and concentrated using heavy media separation through two plants, yielding products of different grades and sizes.
The original processing plant was designed for a nominal capacity of 550,000 metric tonnes per annum. Equipment upgrading and improvements have brought the target production capacity to 800,000 metric tonnes of product per annum. Bootu Creek produces a siliceous ore particularly suited for use in the production of silico-manganese.
In 2019, OMM expects to commence operations at a new Tailings Retreatment Plant. Using a reflux classifier, this plant will reprocess reject material (or tailings), and is expected to yield an additional 250,000 metric tonnes of fines per annum for 8 years.
