Thanks. I think I looked everywhere but there...
If you walk up until you get to the far end of a dragon skeleton on your left, you can jump up onto the rock by the hip bone, and then onto the next higher rock to get over to the malachite veins. The next rock on the left edge of the path past the hip bone is an easier way (as far as jumping) to get to the vein, but make sure you jump diagonally to it (forward and left); if you try to walk up to the rock, and then jump left, you can easily trigger the cutscene there (IIRC that is why I missed the veins; I had already reloaded so I could search the place, and the second time getting the cutscene it didn't seem worth reloading again for the small area left unsearched). Oh well, I still ended up with a couple dozen malachite gems.
