North Drachvald Spur Secret

Hello everybody!
First, I want to thank the devs for this wonderfol release, very happy about it!
And now, those who want to explore the North Drachvald Spur by themselves: DON'T READ the following sentences!
(don't know how to hide the text^^)


I just went out, adventuring the new Drachvald scene, and explored something interesting.
Found a jumping puzzle at a little waterfall, there is a closed door, with a switch.
If you push it, the door opens and there is a skeleton carrying a "Brittle Mine Key".
I searched for the mine, but wasn't able to find it.
Anybody here with a solution?

 

I believe the mine entrance is on the hillside adjacent to the central tower. There is a broken bridge leading to it, but the easiest way to access it is to jump down onto the platform from that central mountain. Once you find the mine entrance, it's fairly obvious how to get to it. @Flientje Vantmeeden

 

Secret's out!

 

Just a suggestion, but spoiler tags work very well for this.
@Flientje Vantmeeden and @mass

 

i found a different key elsewhere in that scene, but nothing to use it on

 

There's also a couple of bandit huts that have locked doors with some loot inside.

 

they weren't locked to me.

 

I had it happen where someone else had already unlocked it, but usually if that happens, most of the loot is gone. It's the two where one locked door is in front and another in the back after you break through the gate.

 

Thank you for your replies!
I tried to use the key at several doors where the bandits are, but wasn't able to unlock them with the Brittle Mine key, there is another key for these doors, which you can obtain from the bandits.
So I'm curious, to which door the Brittle Mine key belongs.
But I'll investigate now, that's something I like very much, that SotA has so many secret doors, jumping puzzles etc.

 

Found the entrance!
Big thanks, especially @mass and @Tetsu Nevara!

 

Glad you found the entrance. It was fun getting at it, but now I have to find the key for it. I'm certain it will eventually drop for me.
