NOTE: This page relates to Deans No. 3 Mine operated by the West Lothian Oil Company, which was at a different location and entirely separate from Deans No. 3, opened subsequently by the Pumpherston Oil Company.

NOTE: There is some evidence that "Mine No. 2" and "Mine No. 3" may have been incorrectly labelled on the 1897 O.S map, and that No. 2 should be labeled as No. 3 and vise versa. Until further evidence comes to light however, it is assumed that the labels on the OS map are correct.

These workings in the Dunnet Shale and the Pattison Shale were ultimately continuous with those from Deans No. 1. Considerable opencast working of the Dunnet Shale took place along it's outcrop between No. 3 and No. 1 Mines. The 1897 OS maps shows a tramway running some distance across the quarry floor before entering the mine entrance in the quarry face. At least one further mine entrance in the quarry face provided access to the Stanley shale by means of cross cut mines from the Dunnet Shale workings.

The 1897 map suggests that the mine was operational at that time, suggesting that , like Deans No. 1, the mine was re-opened by the Pumpherston Oil Company.

The quarry was filled in, and all trace of workings removed, as part of the landscaping of Deans bing in the early 1980's.
