Mines and minerals in Derbyshire (UK): Northern Dale Mines

I visited the Northern Dale mines on the 12th May 2018 and, due to the extent of the mines in the area, revisited on the 15th May 2018. Northern Dale lies to the south east of the village of Wensley and has numerous old mine workings, some reportedly dating back to the 1530's. Access is easy with a path extending from the southern end of the small car park in the centre of Wensley village. It descends behind the village eventually meeting a wooden signpost. Take the Brightgate turn to the left and follow the small path up the hill opposite and through a gate into fields. The path is followed across the fields passing a large restored stone barn on the right. Continue straight on through a couple more fields until the path sharply bends to the right. Northern Dale is in front of you as you approach the bend, with signs of old mine workings on the hill to the left. This whole area is home to mine workings and extends all the way up to Brightgate and Tearsall Quarry to the south west.

Background

As previously mentioned, the area appears to have been mined for lead from the 1500's onward, with references right up to the 1920's. It contains many mines with the typical colourful names often given to Derbyshire mines including Old Ash mine, Lords and Ladies mine, Hit and Miss mine (Tearsall Pipe Caverns No2), Tearsall Mine and Dalefield Mine.

The area is covered with small hillocks marking workings along veins, pipes or flats along with shafts (mostly capped) and some old dressing floors with associated spoil heaps.

Very little information appears to be available though regarding the history of these mines. I have listed references to what I've been able to find at the end of this post in the References section for anyone who is interested.

Mineralogy

Again there appears to be little detailed mineral information available other than the main ore was the Lead ore Galena, which was associated with Fluorspar, Calcite and Baryte.

Minerals found

Specimens were hard to come by as the workings are old and have no doubt been picked over many times during their existence. Some of the workings may well have been reworked in later years for Fluorspar too.

However, with perseverance I was able to find various examples of Fluorspar, Calcite, Barytes, traces of Galena, a green mineral - probably Pyromorphite, and Quartz.

The Fluorspar specimen shown below is interesting in as much as its crystals lie on top of a layer of Baryte cementing occasional broken fragments of an Olivine-Basalt which I had previously come across at Tearsall Quarry. This layered structure atop of solid limestone.
