Opened c.1904 to supply Dunnet shale to the Pumpherston Oil Company's newly reconstructed Deans Crude Oil Works. Known as Starlaw Mine, but unrelated to the earlier Starlaw Pit, site of the 1870 disaster. A separate, earlier Deans No. 3 Mine operated at a site north of the Edinburgh to Bathgate railway.

The history of the "old shaft" shown on the 1897 OS map is unknown, but the 1914 map suggests that this was re-used in the development of Deans No. 3, perhaps for ventilation purposes.
