Clement H. Pead became a member of the Chemical and Metallurgical Society of South Africa in 1894, the year of its formation. He continued his membership after the Anglo-Boer War (1899-1902), when the society was renamed the Chemical, Metallurgical and Mining Society of South Africa, and read a paper before it at some time before the end of 1903. At a meeting in September 1905 he read "Notes on improvements in the cyanide treatment of sands and slimes", which was published in the society's Journal (Vol. 6(3), pp. 76-78). At this time he was employed as metallurgist and cyanide manager at East Rand Proprietary Mines, Ltd.
A few years later Pead moved to Rhodesia (now Zimbabwe) and settled in Bulawayo. By 1911 he was the senior partner in Pead & Frison, assayers, metallurgists and mining engineers, but by 1916 he was practising on his own as "C.H. Pead, assayer, metallurgist and mining engineer". He became a member of the Rhodesia Scientific Association (Bulawayo), probably mainly because of his interest in entomology and related subjects, and read a number of notes and papers before the association that were published in its Proceedings: "Note on the habitat of a lizard and on an arachnid found therein" (January 1910); "Some Rhodesian cicadidae and observations on economic entomology" (February 1910); "Some observations on the pupating habits of a Noetuid moth, Cucullia palliastria" (September 1910); and "Town water" (December 1912). He was president of the Association for 1912/13, delivering his presidential address on "Irrigation" in June 1913.
Pead was married to Adele Fredericka Puzey, who died in 1897.
