A single brick chimney is all that remains of the first offices of the Broken Hill Proprietary Company — the BHP that grew out of Charles Rasp's 1883 silver-lead-zinc strike and eventually became Australia's largest company. The original buildings were demolished in the early 20th century and the chimney was left as a marker.
It stands on a patch of dusty ground at the edge of the line of lode. The site has a small interpretative sign, and on its own is not much to look at — but in combination with the other mining heritage sites it gives a sense of just how completely the early industry has been swept away.
