Mining faster than the rest.

One of the best tricks for mining is that you can double click two or three shovels at almost the same time. This makes resource gathering much faster. The easiest way to click them as fast as possible is to use razor.

It seems you can smelt pretty much any other ore except for valorite without fail, so a good way of maximizing ingot profit is to break your pile into individual pieces and smelt it one at a time. This way you'll have a greater chance of successfully smelting valorite ingots.

Note: When you're smelting, it is smart to wear gloves of mining, that way you have a better chance of not losing any ingots.
