Talk to the man by the mine. Korvend will ask you to help him find the missing miners.
Find the missing Miners
Enter the cave, crawl under the crevice on the left and dive down. Swim to the next part of the mine and use the Focus to locate the miners.
Swim up to catch some breath, dive again and head straight. In the long tunnel you'll find an object which helps you gain speed while swimming. Swim up to the yellow point and press Triangle to quickly swim to the next area, where the miners are.
Talk to the Miners
Swim up to the surface and talk to the miners. They'll give you an explosive you need to blow up the mine cart and dry the mine.
Dry the mine
Dive into the water and swim through the tunnel. Use the ladder and go to the next room. Walk up to the wooden structure and climb the ladder. Turn left and jump over the beams until you reach a small gap.
There are three machines in the next room, killing them being an optional quest objective. You can eliminate them quietly by hiding behind barrels or by shooting mushrooms which will create obscuring clouds of smoke.
Keep going upwards until you find the broken tracks. Jump to the other side and squeeze through the small gap. Scan the area and climb the rock to the top. Go through the low corridor and jump down. Walk up to the ladder and press Triangle to drop it.
Use the Pullcaster to pull the wooden object closer, then jump onto it and onto the tracks. Run up to the cart and plant the explosive charge.
The noise caused by the explosion will lure in nearby machines. Defeat all three opponents and remember to search the crates found in this room. One of the crates can be dropped with the Pullcaster, the other can be reached by walking on the rope.
Return to the Miners
Unlock the exit with the Pullcaster and return to the miners. Scan the area to look for a climbing spot.
Return to Korvend
Jump down and go left through the corridor. Leave the mine and talk to Korvend.
