As part of the Celebration Round 2, got the Task to add 2000 Copper Ore to any Copper Deposit. What's the best way to get the 2000 content to add?
Closest I can see is buying the Copper Diviner 4 times for diamonds, but that isn't like them to not have a Grind option.
If I randomly get Content pieces through the rest of the year, I tend to use them to keep the mines going, not horde them in case some future quest line wants them and if I get a general "add to any deposit" one I tend to use it for higher-level mines like Saltpetre, not Copper.
