Bowen, Sir George Ferguson (1821-1899) Governor of Victoria, signature and seal on an October 1876 indenture granting Edwin Field permission to mine the specified land in the District of Sandhurst. The yearly 'rent' was set at four shillings. Four years later the Mineral Lease was transferred to The Costerfield Gold & Antimony Mining Company. Costerfield is a former mining locality 10 km north-east of Heathcote and 50 km east of Bendigo. It was named after two of the four discoveries of gold and antimony in the locality in 1861. The discoverers were Peniston & Alan Coster, Edwin Field and Mr Youle. The mines were allied to the McIvor district gold digging. The Costerfield Gold & Antimony Company worked the area for several years, sinking shafts to over 150 metres by 1874.
