1. The History
Situated on the slopes of Eyam Dale, Merlin Mine is one of the more extensive former lead workings in the area. At its main entrance level, it crosses two “scrins” (small veins), namely Stubbs and Sycamore. As can be seen from the map below, workings carry on for some distance. The level intersects natural passages and miners exploited small veins for lead ore. The mine also includes several cross-cuts, small stopes and an internal shaft at Stubbs scrin, that gives access to Carlsworth waterfall system. Apparently in the 1793, the mine is listed as being a show cave.

2. The Explore
Second and third visits here in the space of a week. Last time we visited it was in conjunction with Nickergrove lead mine and we were a little jaded and pushed for time, hence the need for a revisit. The mine is a 5-minute hike up the valleyside from the busy Stoney-Eyam road. After the steep walk through trees along the old miner’s track, it’s relatively easy to locate the mine's small adit entrance. The mine has a real cave feel to it and its interconnections with the Carlsworth cave system make it popular with cavers. It is pretty tight and doesn’t open up, bar a few tight steep stopes and a handful of small chambers. It was hard going as it's mucky, very rocky and wet in places too. It’s pretty difficult to take pictures of due to it being narrow and the floor being uneven. This time we explored pretty much all of the mine that’s possible without doing SRT, including a crosscut off to the left after entering the mine. It opened up into a lovely little natural chamber and was well worth the extra scramble.

3. The Pictures

On the way up you pass the 60m deep Carlswark Cavern/Eyam Dale Shaft:

It’s a long way down:

52966379105_82f144e43c_b.jpg


On to the main adit:

52966379775_84bdef6c62_b.jpg


Once in, it’s rocky:

52966146089_4d4e1a181e_b.jpg


And wet in places:

52966145074_0b4675b5bf_b.jpg


Some stacked-up deads along the main adit:

At the T junction, on the left the passage soon ends in this rising chamber:

So it’s back and to the right:

52965404682_458e12fab4_b.jpg


After we go up and over some rocks we get to this collapsed passage that looks like it went to a lower level:

52966381590_66512d3913_b.jpg


Then it’s the whinze that takes you down into the Carlswark cave system:

52966463223_63011a2eb8_b.jpg


So it’s an about turn then a scramble up to the right to join the main drive again:

52966146569_75e10555e3_b.jpg


Pushing on down the main drive, its wet, muddy and narrow:

52966145284_752095db9d_b.jpg


It’s worth it as there’s some pretty formations:

Nice flowstone:

And these lovely cave pearls:

Onwards we push:

52966145939_8fb06ebd15_b.jpg


At the end of this adit, it turns abruptly to the right then immediately into the whinze of doom that disappears into the abyss. Time to turn around:

52965405267_e75d1845e6_b.jpg


Back out and down one of the cross-cuts. After 10 or so metres it pops out of the adit into a natural chamber:

CONTINUED:

A bit of flowstone:

52965404312_931a30c5e3_b.jpg


It goes up a fair way:

52966000801_66cecf836e_b.jpg


And appears to continue along here:

52966379795_2ac24541b6_b.jpg


And back out again:

52966381560_4b9345cd97_b.jpg


Afterwards, when we were out we popped up to the shaft entrance for a shufty. It’s a left turn out of the mine:

52966379305_a000e2d18e_b.jpg


52966144279_914791a78b_b.jpg


It’s rigged:

52966000511_0d3a65873a_b.jpg


But not one to get too close to the edge of if you aren’t doing SRT:

That’s all folks!

Lovely set and in such difficult conditions. The cave pearls and formations are beautiful to see.
This kind of report shows why caving isn't just for anyone. Just the boulders under foot here and the squeezes are enough to cause injury, without experience. Admire these reports greatly. :)

This is actually the most interesting thing in the report

It’s a rock stemple cut to size to hold the waste rocks in the stope”dead’s” Usually miners used wooden stemples , due to weight easier to move around & labour costs . over years they rot out on top of the stemples is usually a log roll holding all the dead’s . This is what is often found on the mines passage way floor it’s not actually a collapse of natural rock that people think it is .
