Malachite, that is NOT in the area around Hinterland past the dragon?

I farmed the areas, but being a high level all I get is red templars, no bandits anymore. I have try Val Royeal with the guy that sells valuables, but he doesnt sell gems "seperately." I have found one malachite, but it took about 20 freaken hours on the war table. To many it might be a good idea to eliminate most of your war table objectives to find malachite farming resources for I seem to have found it that way. I am wondering is there another place to find this junk. If anyone in EA sees this add a new tab called "journal related valuables and make sure it does not take up inventory space or bring back the chest and put it in our bedrooms like in (spoiler) our skyhold chamber room or our small hut home in haven.
