The seam, at present worked by a pit 27 fathoms deep, average 3 feet 5 inches in thickness, all clean shale. It lies at an easy angle of 1 foot in 8, has a good roof and pavement, requires little propwood, and is on the whole a fine working and favourable for cheap production. Lanark Oil Company Ltd prospectus, published in The Scotsman, 25th July 1883.

...the Chairman supplemented his opening address by stating - as bearing on statements that had been circulated to the effect that there was no shale at Greenfield - that these had been carefully tested, and that the very first bore gave them a seam of shale of 3ft 6in., within five fathoms of the surface; another bore reported that afternoon, gave them a seam of 4ft 5in. (Applause.) AGM of the Lanark Oil Co, reported in the Scotsman, 17th April 1885 (The Lanark Oil Company Ltd was liquidated the following year).
