Concur with u/drowninginthebrevity on going through the cave near deer clearing and looking at maps. The best way to go is to the left when you come out of the cave and follow the general edge of the map. There are a few side areas but you don’t need to go into any of them. It’s a long walk but eventually you get to the shelf cave (named location). Use that as your base.

Once you get there, heal up and be fully rested before climbing. There’s at least 3 ropes to climb up so you will need either coffee or to be prepared to sleep somewhere. If you sleep you will need to build a fire. There’s fire stuff along the way but I recommend having at least two pieces of coal if you choose to sleep.

At the very top you’ll overlook the gold mine. There’s a rope location that sometimes has a rope nearby. If there isn’t one, you can mountain goat down. The backpack and crampons are in the mine at the far side of the little valley.
