Was there mineral extraction in the Highlands in prehistoric times?

by Jonathan Wordsworth

The recent Zoom lecture by Matthew Knight on the Late Bronze Age Hoard found in a peat cutting behind Poolewe in 1877  (the talk can be viewed on the Gairloch Museum Youtube channel at Poolewe: The last Bronze Age hoard in Scotland? by Dr Matthew Knight) and the recent Feats of Clay project (http://archhighland.org.uk/feats-of-clay.asp) led by ARCH relating to a metal-working site with rare clay mould fragments found during excavations at Bellfield, North Kessock, demonstrate bronze casting was occurring in the Highlands.  Together with the Stittenham Axe Mould these are important finds for Late Bronze Age Scotland.

But this is a speculative blog examining the possibility that there might have been copper and other ores extracted in the Highlands during the Bronze Age and is meant to stimulate research by NOSAS members on some of the ore sources.  While current research has not identified any prehistoric mining in Scotland, except possibly in South West Scotland, there is certainly nothing on the scale of the Great Orme mine in North Wales. The received wisdom is that the copper and other metals alloyed with it such as tin, zinc and to a lesser extent lead, were brought into the area as ingots from metal extracted from elsewhere in the British Isles or from further afield in continental Europe.  Recent metallurgical analyses have shown very mixed compositions for the metal tools and the recent work on the Poolewe Hoard shows at least 5 different mixes of metals to produce the surviving material (see the research results at https://www.academia.edu/44587605/Poolewe_The_last_Bronze_Age_hoard_in_Scotland).

Certainly by the end of the Bronze Age it is likely that a variety of broken or discarded objects would be thrown into the mix for melting down, making it difficult to identify the original ore source from trace element analysis.

However research over a number of years by the British Geological Survey has mapped extensive copper ore sources in Wester Ross and some of these have even been looked at commercially (e.g. https://resources.bgs.ac.uk/meiga_reports/meiga/ae173.txt) and the ‘gossan’ at Gairloch is even used as the frontispiece for the British Geological Survey report Minerals in Britain – Copper (which can be viewed online at https://www2.bgs.ac.uk/downloads/start.cfm?id=1324)

Experimental Archaeology: Learning about Technologies in the Past

by Susan Kruse (ARCH and NOSAS)

Thanks to funding from Historic Environment Scotland and the Heritage Lottery Fund, ARCH launched an exciting project ‘Experimental Archaeology: Learning about Technologies in the Past’ in October 2017. The project had three main strands. In the first year, 13 experimental archaeology days and 10 school visits took place where craftspeople demonstrated and explained different technologies used in the past. The workshops were filmed and the edited videos and blogs for each workshop can be accessed on the ARCH website.

In the second year, the objects resulting from these workshops will then be used to create loans boxes which will be freely available to borrow. Our workshop leaders often generously provided more than one object. An archaeologist and teacher will now work together to create learning materials, so that the loans box and videos of the experimental sessions can be used in schools and other groups. The project already has attracted a wide and diverse audience, and we hope that the loans boxes will also contribute to this legacy.

The idea for the project emerged from North Kessock & District Local History Society’s Feats of Clay project, where ARCH helped facilitate a visit by Neil Burridge who demonstrated Bronze Age metalworking. Everyone in the audience was caught up in the excitement of the day, and learned so much about how objects were made, what raw materials were needed, and how craftsmen in the past managed without gauges and modern equipment.

In the first year 13 workshops took place, one a month, each showcasing a skill from the past, spanning from earliest settlers to more recent times. The workshops were exciting to attend, but were also filmed.
