Strategic Resource Facility
Strategic Resource Facilities produce a given strategic resource every turn, similar to Strategic Resource Extractor, regardless of whether or not the owner has researched the appropriate technology; for example, it is possible to collect Titanium from a Titanium Facility without having researched Alchemist's Furnace. This makes Strategic Resource Facilities one of the quickest ways to attain new strategic resources in the game, since they will start producing as soon as the facility is revealed; the owner doesn't even need to be in the same technological Era as the appropriate extraction technology, since the facilities are revealed as soon as any empire reaches the appropriate Era.
Additionally, the output of Strategic Resource Facilities can be increased by 50% by controlling the ocean region that facility is located in, and by another 50% for controlling the Strategic Boost Facility. These bonuses are multiplicative, making the maximum possible output of a Strategic Resource Facility 2.25 per .
Strategic Resource Facilities - along with Luxury Resource Facilities - are not considered "unique", and are therefore the most common type of facility.
Facilities, like this one that mines [Strategic Resource], are platforms that provide bonuses and resource exploitation. You can never know how much will be exploited by the fortress.
