10/02/1899 – Ardrossan and Saltcoats Herald – The Bourtreehill Coal Coy. have now struck a splendid seam of ell coal in their Warrix pit near Irvine, which when opened out will give employment to a large number of men. The Ladyha’ was sunk through some time ago, and the coal with the clay under will make a good working. From this seam, there will be a plentiful supply of coal and clay to last the fire-clay works for many years. The sinking operations were retarded by a strong post of whinstone and other difficulties, but both colliery and fire-clay works will, it is expected, now be rapidly developed.
