The Company of Mineral and Battery Works was, with the Society of the Mines Royal, one of two mining monopolies created by Elizabeth I. The company's rights were based on a patent granted to William Humfrey on 17 September 1565. This was replaced on 28 May 1568 by a patent of incorporation, making it an early joint stock company. The Society of the Mines Royal was incorporated on the same day.
