Bianca says Corypheus is getting his red lyrium from the thaig Hawke and Varric discovered years ago - on their expedition into the Deep Roads under Kirkwall. It may be possible to reach it using an entrance to the Deep Roads somewhere in the Hinterlands.
Available after completing the main quest Here Lies the Abyss. Talk to Varric to trigger a cutscene when he is speaking to a female dwarf called Bianca. She explains that there is a lead for Corypheus's red lyrium source, as the location of a thaig inside Valammar has been leaked. Agreeing to help her starts the quest.
Enter Valammar in the Hinterlands. The fastest way there is teleporting to Upper Lake Camp. Bianca will be waiting inside Valammar and accompany the group. Head to the lower terrace and let her open the door.
Kill the mobs in the room and loot everything. Codex entry: A Different Darkspawn? can be found here as well. The second key is found in the end of the room, on the desk. In the following cutscene, it is revealed that Bianca was the leak - she gave the key to the red lyrium mine to a corrupted Warden (Larius/Janeka, depending on the previous choices during Legacy), so she unknowingly helped Corypheus. Return to Skyhold and speak to Varric about what happened.
Note: Be sure that the key is the last thing you take, otherwise after the cutscene the door will be locked behind you with no way to get to the rest of the loot.
