Selection Trust was a British mining finance house. It was started in 1913 by A. Chester Beatty, a mining engineer from the United States. After the end of the First World War, Beatty built up a substantial portfolio of mining interests, many of them in Africa, but others in Serbia and in Siberia. Initially the company began operations by sharing an office at Number One London Wall in the City of London with the consulting firm of Herbert Hoover, a fellow American mining engineer.
