In February 1951, South Australian Barytes Limited became interested in this mine, held under claim by Reginald John Alfred Larsson and requested an inspection by Department of Mines officers. This request was repeated, and endorsed by Larsson in January, 1954. A topographical and geological survey was carried out in May, 1954 by C.J.R. Kingsbury and J. McCahon. The survey was done with theodolite by stadia traverse, but was not tied in to any fixed datum. The "section fence" on which the claim boundaries were based now appears to be away from the true section boundary by some hundreds of fact. Alternative names which have been applied to this mine are, "Castambul Estate" and "Varcoes".
