Azurite Mine Stuck

I am doing my first play through so this could be a me issue but I'm stuck.

When I first went to the mine I did the first node fine and got some azurite. I made the 2 flares and 1 dynamite. I didn't realize what the fractured walls were so I wasted the dynamite (still have the flares) so the starter quest is still unfinished.

I have lot's of Sulphite from the campaign so I went back and I did the few connected nodes and got some weapons and jewelry but no more azurite.

I've now done the 4 nodes that directly connect from the mine entrance and I'm stuck. I have a yellow line connecting a node back to the mineshaft but I nothing happens when I click on the nodes in the mineshaft. So there is no new nodes I can actually get to let alone any that give me azurite.

Thanks

Thank you but there are none it will let me select. The only nodes I can move between have all been cleared and none were azurite. I am stuck to selecting only a handful of nodes because it won't let me select the mineshaft to move deeper.

I figured it out this morning thanks for trying to help. I was trying to get the cart to move to a yellow node on the mineshaft because I'd never been down it and didn't actually check that I could use the offshoots from further down the mineshaft even when my cart icon showed very far away.
