Worked in association with Westwood No. 13, both pits were in operation prior to 1870 and continued to be worked into the 1880's. Both were served by a branch of the Addiewell and Polbeth railway, crossing the Breich Water by viaduct.

Maps suggest that workings from No. 12 & No. 13 were linked to Fells Shale workings beneath Tenantsmarch, which were in turn linked to workings in Addiewell and Polbeth. It is unclear how workings beneath Breichdykes were linked to those of Westwood No. 12 & No. 13, and whether these workings continued beneath the Breich Water to link with Fells Shale workings from Addiewell.
