1. If you are in the workshop due to completion of the previous task, simply talk to Boric again. If you needed to gain levels or perform some other action between these last 2 tasks, return to Doric's workshop and climb down the stairs to the North of his building. Down here, locate Boric near the furnace and ask if he has any more tasks for you to do. Speaking with him you will learn that he has managed to secure a deal with the Mining Guild... well, almost. It seems that they want a show of commitment before they will fully agree to the deal. You will now need to collect 15 Orichalcite ore and 10 Runite ore to help prove they are an honorable company.
   
   
   
   
2. When mining the ores, you must mine them from within the Mining Guild or the nearby Resource Dungeon for it to count! Ore collected from anywhere else will not satisfy this task. Use of Orichalcite stone spirits and Runite stone spirits can be used to speed up this task, however, your ore cannot be within an ore box or noted when given to Boric. Once you have collected all the ore needed, a message will appear in your chatbox.
   
   
3. A few more notes on this task. If you use the Imcando pickaxe and it smelts your ore, while it will count for the Guild's tally, you will still need to return with the proper number of ore for Boric. Simply mine another one or two as needed to suffice him. If you mine a gemstone while completing this task, you will have a similar issue. And finally, extra ores gained through Varrock armour(1, 2, 3, or 4) will not count toward completion of this task.
   
   
4. Now that you have the ore, return for the last time to Doric's workshop and climb down the stairs to the North of his building. Down here, locate Boric near the furnace and speak with him. You will give him the ore and he will reward you with 8,000 Mining experience and 24,000 charges on your Gofannon amulet.
   
   

Congratulations! You have completed all of Boric's tasks!
