Two more shots of one of our favourite sections of a brand-new mine we recently explored for the first time… 👀

This is the main stope, which we think is the largest man-made underground ‘cavern’ in the mine — or at least the largest we could access. It must be well over 2m wide and 20m tall here! 🤯

It’s incredible to see the full width of the tin lode left behind in this support pillar. The mine was last worked in the 1910s, giving it a surprisingly modern feel despite its ancient origins.

And just look at those rock colours! 😍

We were at the deep adit level, around 200ft below the surface. Swipe for the silhouette shot — which do you prefer? 👇

More from our recent exploration of this brand-new mine! ⛏️

Hidden deep underground, we discovered artefacts and old workings left behind by the last miners who worked here in the 1920s. One of our favourite finds? Vintage detonating cord with blasting caps still in place. 😮

But what makes this place truly special is the thought that these images and videos will almost certainly be the first ever captured of these forgotten tunnels. For nearly 100 years, much of this underground world has remained in complete darkness, untouched by light since the miners themselves last walked these passages.

Until now. 💡

A century of silence, frozen in time, brought back to life by the glow of our LEDs.

If these walls could talk, what stories would they tell? 👀

A few photos from our first exploration of a brand-new discovery: a previously unexplored (by us) Cornish tin mine! ⛏️🕯️

It’s probably been decades since the last explorers were here, and these could well be the first photographs ever taken underground. Just imagine this place lying in total darkness for all those years, hidden away and forgotten, until we stumbled across it one afternoon. Pretty special to think about! 🤯

We were delighted to find the main shaft completely open, although unfortunately it had suffered from severe fly-tipping and was choked with rubbish around 10m down. Luckily, some adjacent stoping remained open, allowing us to abseil down past the blockage to just below the shallow adit. From there, we descended a scree slope made up largely of fly-tipped agricultural waste to reach the deep adit.

And this is where things got really interesting! From the deep adit, we were able to walk almost its entire length, simply following the tunnel through the mine. An absolutely amazing find, and a rare opportunity in old workings where major collapses so often prevent further exploration.

The rubble piles you can see in the photos are actually collapsed boxholes and ore shoots, remnants of the mine’s original workings. We also came across some lovely 1920s artefacts, offering a little glimpse into the people who once worked here. 🖤

An incredible underground time capsule, hidden in the darkness for decades. And there’s plenty more to come…

Stay tuned for the next instalment! 👀
