Golden Frontier Old Mine

The Old Mine uses the Prospectors and Prospector’s sets to mine for Nickel and Zinc Ore. You will need free Prospector’s (cannot be working)to be able to dig for the new ores. The more you upgrade the Old Mine, the more Prospector’s Sets and time it takes will grow, but you also get more Zinc and Nickel Ore to trade in the Exchange House. You will need to have the Old Mine Upgraded to stage 2 in order to go prospecting inside.

After upgrading to stage 2, you will be able to use 1 Prospector to mine for Zinc and Nickel Ore. It will take 15 minutes to work in the mine. When finished, click the Yellow “Gather Resources” button and receive what was mined. You will receive 2 Zinc and 2 Nickel Ore.

In order to upgrade the Old Mine You cannot have anyone working inside. Click the blue “upgrade building” button to upgrade your Mine. I wouldn’t advise upgrading too quickly. It costs more prospector sets to mine after each upgrade.
