Slant Drilling

Slant Drilling is a patent that allows for mining in adjacent tiles. This means that any resource gathering building will also gather from adjacent tiles of the same type. (Though, for example, with Slant Drilling a Metal Mine placed on an Iron deposit could gather from an adjacent deposit containing both Iron and Aluminum, since Aluminum is also able to be gathered by the Metal Mine building.) If a lone resource tile is claimed, a player with Slant Drilling can place a mine in an empty spot adjacent to that tile and will be able to gather that resource.

Note that any gathering building's output is capped (default 2.0). So, for example, even with Slant Drilling a Water Pump placed on a medium water deposit and adjacent to a high water deposit will only output 2.0 water, notwithstanding that the theoretical total water availability to the pump is 3.5 (1.5 from the medium plus 2.0 from the adjacent high). This output cap, however, can be increased through normal means such as adjacency bonuses and optimizations.
