Howdy Wellard,

during your travels, clicking on the various ore deposits brings up a message confirming that you've found them.

If you get corrupted messages then AFAIK you don't get credited with the discoveries.

In the lead up to getting the keep you can find 8 ore veins :

Act I
- iron x 2
- cold iron x 3
Act II
- Alchemical silver x 2
- mithril x 1

There are another 8 veins to find (1 x mithril, 2 x dark steel, 5 x adamantine) later in the game.
