Method 1 (Easy)
Run left, and try to triple jump on the left corner. If you move fast enough, you can beat the thwump before it comes. Keeping with as much momentum as possible, walljump off the right side of the shaft and then jump off again to beat the second thwump, then walljump a third time off the left wall to exit.
If you can't do this, then instead bait out each thwump, wait for the thwump to start to recede back into its hole, then quickly walljump upwards.
In the next part, slide down each cranny and pick up the gold and the exit switch. Run and jump to the right side, landing between the first pair of mines, jump again to the slope, then up to the gold and the door switch. Jump back down, using any of the slopes to stop your fall. You are now in the exit area. It is patrolled by a single guided zap drone. Pick up as much gold as you can, then run towards the exit, dodging the drone while doing this.
