After entering the ruins (TH3-A), continue the tunnel to the end. Eliminate geths (you need to act quickly, because there aren't many covers there) and get into the elevator (TH3-B). After getting out, eliminate flying geth assault drones (remember, that they are resistant to biotics but susceptible to tech powers). Then take another elevator down (TH4-D). Step off down the broken walkway and then turn toward the blue field to find Liara.

She'll be trapped in a Prothean force field (TH5-1). To free her, you'll need to get to the switch which is behind the barrier. Keep descending the ramps until you reach the bottom of the mine (TH6) where you will find more shock troopers and snipers. Eliminate them.

At the bottom you can take some objects from the containers. Activate the mining laser (TH6-1) through trial and error method using the correct sequence (right switch - green color, wrong switch - red color). Here's the right sequence: AXBY.

Go trough the hole, make sure your squad is well equipped and ride the elevator up. Free Liara. After a short talk you'll learn that you should leave the mining area as soon as possible. In order to do it, you'll need to use the elevator in the tower. There you'll encounter the krogan Liara told you about as well as group of geths.

You can't talk your way out of a fight, so you must defeat the krogan battlemaster along with his geth soldiers. Remember to keep distance from the krogan, because he's deadly dangerous infighting. Find the nearest cover instead, eliminate the geths and then concentrate on the toughest opponent. Be careful not to be hit by biotic attack which will knock you down. To eliminate the krogan, use all talents and abilities of your squad. You can also order your subordinates to approach the enemy. He'll concentrate on them and you'll be able to attack him easily.

A moment later you'll be already safe on Normandy. After crew meeting, during which Liara will speak her mind about prothean extermination, you'll be able to contact the council and report on the mission. Then you may talk with the members of your squad, buy something from the deck dealer and choose another destination.
