The Avebury deposit was discovered in 1997. After operating for less than two years the mine was placed on care and maintenance in 2009. In late September 2016, MMG entered into a share sale agreement with Dundas Mining for the purchase of the Avebury mine. The consideration comprised a deposit of A$1.5 million payable on signing, and another A$23.5 million payable on completion. While the sale was subject to various conditions which included MMG Board approval, the sale was completed in July 2017. It is understood that Dundas Mining plans to restart operations as soon as possible, but Wood Mackenzie has conservatively assumed restart in 2019. The concentrates are relatively high in MgO and arsenic.
