Joseph Jeffery died in a nursing home at Brighton on June 29th, 1939, at the age of 52.

He started his professional career in South Africa in 1903, first with the Ginsberg and Balmoral Gold Mine and afterwards with the Randfontein South Gold Mining Co., Ltd., in the meantime attending evening classes at Transvaal University College. In 1906 he entered a two years’ course at the Camborne School of Mines and then returned to the Randfontein South Company.

In 1911 he made an extensive tour of mining fields in Colombia, Panama, Mexico, the United States and Canada, and in the following year once more returned to South Africa, this time to the Langlaagte Estate and Gold Mining Co., Ltd.

On the outbreak of the Great War he was attached to the South African Field Artillery and saw active service in the Transvaal during the Rebellion and in German West and East Africa. He returned to the Langlaagte Company until 1920 and in 1921 was appointed assistant mining engineer on the Chorolque section of the Cie Aramayo de Mines en Bolivie, subsequently reaching the position of acting manager. He remained with that company for a number of years and on his return to England joined the board of Mining and Chemical Products, Ltd.
