Guild Wars 2 – Help the Miners in their search for ore by fighting the dredge

Head to the Southwest of Edenvar's Homestead and you will find Surveyor Falki. Talk with him to learn more of what is going in inside the nearby cavern.

Surveyore Falki: Listen to those dredge! What a menance.
Hero: How can I help?
Falki: Go into the mine and help clear the place out. Thsoe vermin have turrents and noisy machines all over the place.

 You can also talk with Foreman Afvior to learn more of the events that lead to this situation.

Foreman Agvior: Those dredge have my team! Anyone who didn't die or escape got shut into a cave with destroyers.
Hero: What happened?
Agvior: We were digging when they blindsided us. Twenty of my miners are dead, and the dredge took the rest away. Those miners are my family! I need to get them back.
Hero: A) I'll help what's the plan? B) Why don't these other guys help you?
Agvior B) They say a true norn should be able to fight their way out by themselves. I think true norn fight for their friends.
Hero) I think you're right. Let me help D) What's stopping you from rescuing them yourself?

This ultimately leads to an event in the area where you head into the mines and take on a number of dredge and their machines. This is great for making quick progress through the quest as well. If you find any raw dredge ore, just skip on it. It is only useful for a few things and most of those are other quest that you can't always be involved in.

Head into the mine itself to find everything you would want to complete this quest. There are a number of dredge around that are in need of killing. They will come charging after you as quickly as they see you.

As you head deeper into the mines you will find unconscious miners as well. You will earn credit for reviving any that you find. If you happen to find any in cages you can free them as well for additional credit.

Once the quest is complete you will receive the letter, “Kudos” with 79 copper:

“The ore we got out of those dredge mines has been a lifesaver. Hopefully, they'll think twice before they attack us again. Best regards – Surveyor Falki.”
