Just for RP's sake, even if she doesn't actually mine, I have now found 2 corundum, 1 iron, and an orichalcum vein in close proximity to Heljarchen Hall. I like it. To me it's the least glitchy house, and you can see any enemies easily. One nearby giant camp you get no trouble from (but it will respawn), and the one close to the house has never respawned for 2 characters once killed. The ore is a bonus, a steady, if small, supply. I check them periodically, and any ore goes to the cellar and into the ore bins.

Well the little wife happily mines the clay deposit over at Windstad Manor, the one right next to the wood pile. Does it have to be ore that is mined?

So by now, Heorogar has been able to reconnoiter all the different homesites during his civil war missions. The viewfield and those scattered ores around Heljarchen do give it the edge at this point. And he's already made friends with the neighboring farmer over that creepy jester incident.
