Hong Kong Works of the China Mining and Metal Company Ltd. [c.1920-1928]
The Hong Kong Works of the China Mining and Metal Company Ltd. The company produced non-ferrous metals from 1919/20 onwards. After 1924, the company came into trouble (reason unknown to me) and was finally dissolved in 1928.

The buildings (or part of them) were used after 1928 by other companies , they seem to be still there in 1952.
