South Crofty Mine in 2005Welcome to the website for the 2020 "INTERNAMHO" conference. NAMHO is the National Association of Mining History Organisations with members based in the United Kingdom and the Republic of Ireland.

In the year 2000 an international mining conference was held in Cornwall, led by NAMHO member organisations. It has been decided that after 20 years, the experience from 2000 should be repeated and the conference is now being organised.

The conference is based in Redruth, Cornwall. The venue for the lectures will be Redruth School and the social events, including the conference dinner will be in the Penventon Park Hotel. These venues are with a few minutes walk of each other. Camping will be available in the grounds of Redruth School.

The conference will be held over a long weekend from Friday, 3rd April to Wednesday, 8th April 2020. More details will be provided on this website as the programme of lectures and events is developed.

The theme of the conference is "Copper, tin and gold". The link between these topics is provided by the Nebra Sky Disc which is pictured in the heading for this website. Details of the disc may be found on Wikipedia ( but in brief it was found in 1999 in Germany and eventually deposited in the State Museum of Prehistory at Halle. The link with the conference lies in the fact that recent analysis* found that the gold used in the first phase was from the river Carnon in Cornwall, United Kingdom. The tin present in the bronze was also of Cornish origin.

So Cornwall did not only produce copper and tin (and slate and china clay and a little lead, cobalt and tungsten) but also gold. Before, during and after the conference, opportunities will be provided to visit some of the sites. These visits will be publicised through the Surface and Underground Trips pages on this site and it is hoped to use coach transport to minimise costs and ease problems of finding the sites and parking. Sadly, Cornwall offers few opportunities for underground visits and the organisers will be unable to suggest any sites other than those being offered on the schedule of events.

Besides the lectures and visits, NAMHO Conferences have a tradition of providing a meeting place for like-mined people with opportunities to socialise and often with appropriate with local entertainment of some form. To support this aim, a conference dinner has been arranged and there will be a suitably well-stocked bar.
