UNDERGROUND PROGRAMME - 2022

  • Coate Moor Ironstone Mine
  • Eskdaleside Ironstone Mine
  • Hutton Lowcross Jet Mine
  • Sil Howe Whinstone Mine
  • NAMHO 2022 will feature rather more surface trips and drift mines than usual, the nature of our geology and local mining techniques tends to leave complex mazes with the potential for bad air, so smaller guided groups are also essential.

    All subsurface trips will require full underground gear to be worn by all attendees, including hard hats, lights and suitable footwear. Knee pads are valuable in several of the crawls but these are up to individuals.

    Trips leaders have been instructed to bar any attendees who do not have suitable equipment or behave in an unreasonable or unsafe manner.

    You may notice there are no SRT/ropework options on offer this year, simply because there are none in the local area (well at least none that don't end in deep water and low oxygen !)

     

    Coate Moor Ironstone Mine

    This small ironstone mine was active for a few years around 1870. The workings are quite extensive and contain some excellent features illustrating the working methods of this period. Over the past few years, with the co-operation of the landowner, CMHS have restored access to the workings which are usually kept locked.

    The visit will consist of much bent walking with some areas very rough underfoot and a few short crawls. Conditions are generally dry but with some sections wet underfoot.

    NOTE : This site is on private property and can only be visited as part of the organised programme.

    Eskdaleside Ironstone Mine

    Situated on a sloping site in the Esk Valley, this mine operated at various times between 1847 and 1915. Surface remains include a CMHS restored furnace chimney, powder house and 3 drift entrances.

    Access to the mine tour is by way of a steep flight of steps and then internally via a short crawl through scaffolding. The mine is mainly dry, but Wellingtons are recommended. The air is good, permitting observation of the methods of working and various artefacts.

    Hutton Lowcross Jet Mine

    The North York Moors is the type locality for Whitby Jet, which is a black form of fossil wood used in the manufacture of jewellery. The material has been obtained from the coastline as sea washed pebbles since antiquity, but the boom-time of Jet jewellery manufacture was the Victorian era, where the main supply of the material was from inland Jet mines.

    The visit will be to one of these mines which is in shale, involves significant crawling and passing through a complex labyrinth of passages between two entrances. The area visited will be largely dry, but some dampness may be encountered during the hour-long underground journey and on the half hour's walk to the entrance if it is raining. Full subsurface gear is required, plus the ability not to be phased by shale from the roof falling down inside one's clothing.

    NOTE : This site should only be visited as part of the organised programme due to the complexity of the workings which are a 7km maze.

    Sil Howe Whinstone Mine

    Whinstone was extracted from the Cleveland Dyke from the 1860s to 1951, initially through quarrying and then as a mine. Rock was transported by tramway from the quarries to a crushing plant at Goathland station and mainly used as roadstone, including 'setts'.

    Access to the mine is via a 500m adit, which is very wet with flowing water and lowish roof which is back bending. The mine is well ventilated and is dry and extensive with good headroom in most areas, but exploration demands some crawling and climbing on loose rock and dirt, with occasional short but steep climbs or drops.

    NOTE : This site is on private property and can only be visited as part of the organised programme.
