A trip to the Knoydart mica mine

James Westland

James Westland answered our call for summer adventure stories. Here he reveals details of a journey to Scotland's west coast.

During World War 2, mica was in short supply. India had been the main supplier but an alternative source was needed. Several localities in the Highlands were identified, but the most productive was also in the most remote area imaginable - on a hillside above Loch Nevis in Knoydart.

The plan for this trip was to visit the old workings and collect some specimens if possible. I am a geologist by training, having studied at St Andrews in the late 70s. I have been intrigued by this location for quite some time and have been meaning to visit it - a fine spell of weather in May 2008 seemed to present me with an ideal opportunity. And I didn't expect the midges to be too bad either!

The adventure, day one

Hills from near campsite

There are only two ways into Knoydart - on foot from either Kinlochhourn or Loch Arkaig or by boat from Mallaig. The boat is definitely the easier option! I managed to get a lift over with one of the private operators who had arranged to take over a large party who were on holiday. I arrived in Inverie about 1:30 pm.

I had arranged to stay at the Knoydart Foundation Bunkhouse, located at the east end of the village. The warden of the Bunkhouse, Isabel, made me very welcome - this was the first time I had stayed in it - I thoroughly recommend it. After a quick bite of lunch it was time to start exploring.

Monument, Gleann Meadail

I spent Saturday afternoon exploring Gleann Meadail. The path that runs up this glen leads eventually to the head of Loch Nevis where there is an excellent bothy called Sourlies. Form Sourlies there is a famous pass called the Mam na Cloich Airde which takes one through to Loch Arkaig where the public road ends. I have fond memories of the Mam na Cloiche Airde - one of the most dramatic hill passes in Scotland.

Folded rocks

I followed the path up Gleann Meadail taking in the geology en route. Most of the rocks in the area are Moine Schists and some of them have been folded into the most remarkable patterns. The effect has also been enhanced by ice-smoothing and polishing during the last ice age. The pictures show the effect. After taking several pictures and working out my route for the next day, I returned to the bunkhouse by the same well trodden path.

Day two

Hills to north

I awoke to more blazing sunshine (and hungry midges). The weather forecast was holding up well! As I headed up Gleann Meadail, the mica schist pebbles on the path glistened in the sun - a hint of things to come maybe?

There doesn't really appear to be an easy way to the mica mines. They lie high up on a ridge running off the peak of Sgurr Coire nan Gobhar at an altitude of about 1800 ft. There isn't really a path as such, so it was a case of picking the line of least resistance up the hill and round to where the mines are located. The distance is not actually that great - only a couple of miles, but there is affair amount of rough walking involved. It is typical Knoydart type territory - rocky, craggy, steep - a scene enhanced by the backdrop of the sea and the islands in the distance. First class hillwalking which would only have been enhanced by the presence of snow on the peaks (although a blanket of snow may have made the hunt for the mines rather more challenging!)

Loch Braomasaig

I arrived in the area of the mines about noon. They lie above a small lochan on a spur running from a subsidiary peak called Tom an Neoil, the “hill of the cloud”. To the south lies Loch Nevis, one of the most fjord like of the Scottish sea lochs, and the perfect backdrop.

The mines are not really mines in the strict sense - they are more like small quarries. There are huge amounts of mica lying around and I collected several samples. The mica is found in a rock called pegmatite which is like a super coarse granite.

Big hammer and pegmatite

Also found in the pegmatite is the mineral beryl. I managed to find 4 pieces of this, its distinctive green colour standing out against the pink of the feldspar, the silver of the mica and the white of the quartz. The pictures show the samples - I have included my hammer for reference, but many of the mica pieces are up to 6 inches in size.

Mica and hammer

One of the mines has a building nearby in a ruinous state. Inside the building lie the remains of what looks like some sort of compressor, made by the delightfully named “Lead Wool Co Ltd, Snodland, England”. At one of the other mines I found an old barrow, rusting away in its final resting place, its labours over, slowly disintegrating in one of the remotest industrial sites in the UK.

I took some more pictures then headed back down the way I came. Much easier on the descent, even with a rucsac full of rocks and hammers!

Day three

View to Eigg and Rum from mine

As I was getting the boat back to Mallaig at 11:00 am, there wasn't a lot of time to go for a long walk but it was nice just to have a stroll about and plan some walks for a future date.

After lunch in Mallaig, I headed off to Loch Morar and the path that runs over to Stoul on the shore of Loch Nevis. I wanted to see and to get a picture of the hill where the mica mines are from the other side of the loch. And also to get a view of the stunning peak, Sgurr na Ciche at the head of Loch Nevis, surely one of Scotland's most spectacular hills, rising like a mini Matterhorn at the head of the loch.

Boat leaving Inverie

Unfortunately, the weather wasn't quite so bright and the lighting was very “flat”. The pictures however give a feel for the area which has a great fell of remoteness about it. And after spending some time by the shore of Loch Nevis, it was back to the car and off home again!

So that was that, my visit to the mica mines. There is always a danger when you read about a place like this that an expectation can be built up and that the actual visit can be an anti-climax. I can honestly say that this was not the case. The weather played its part, no doubt but the combination of scenery, location and the sheer sense of wilderness made for a memorable trip, my first to Knoydart for a very long time.

Thanks to everyone I met there, especially Isabel at the bunkhouse who was very helpful and friendly - hope you enjoy the mica sample!

I was last at the mica mines when I was about 10 years old, so that would be about 1969. My father was a mining engineer and wanted to see them to see if there was any potential for reopening them, which sadly there wasn’t.We hired a small boat at Mallaig and moored at the closest point.I remember the compressor shed, it looked like somebody had just turned it off the day before!But the thing that I remember most about it was that there was a small building which must have been the miners mess hall. Inside was a table and chairs and there was still crockery and cultlery on the table!It looked like the Mary Celeste!

Re Daves comment: Thats interesting about Garve and the HIDB. Used to work for the Enterprise Network (HIE) and never heard about that! I was up at one of the locations in that general area a few months ago - near Scatwell. Its a fairly easy to get to, but very overgrown. Got some nice specimens of pegmatite. Cheers! JW

The Garve diggings were quite extensive but also remote. Now buried in forestry plantation I think. The pegmatite at Garve was very pretty with tourmaline and garnet as well as mica. I have some old maps and details from a 1969 survey. Some information was held by the HIDB.

sunil modi,hi! Just picked up your comment. The mine was only used for a few years during World War 2. The mica was of good quality but in a very inaccesible location. All that really remains now are a few workings up on the hillside - I was back there a few days ago. Several other places were used for mica production during WW2, but the Knoydart location was the best - it produced the largest pieces of best quality. After the war, I presume that supplies started again from India.

sunil modi
Pls let me know more details about the mica mine

I am interested to know more about this mine as we are the largest exporter of mica from india since 1912

James Westland
Tim, its a good question. Mica was used in a lot of different ways, but mainly in electronic components. It is a very good insulator, both in terms of heat and electricity. The mica was mined between 1943 and 1944. I am not sure if they stopped mining it because they were able to get it from India again (which was the main source) or becasue it was worked out. There are still a lot of large pieces lying about so I suspect it wsnt completely worked out. Garve in Easter Ross was also prospected for mica, but the Knoydart stuff was of better quality. There seems to be very little information about this whole business. Most of the data I have found has been from the excellent SCRAN web site www.scran.ac.uk The Scottish Cultural Resources Network - a sort of online museum. Go to it and try a search on "mica" and "knoydart" or mica and "pitlochry" - lots of pics. A pamphlet WAS published by the British Geological Survey, but it is hard to come by. Maybe a University geology department would be the best bet. Hope this helps! JW

Have you any information on what the mica was used for and when - it most have had great value to go to the trouble of mining it in this location
