How a mineral discovery could change Ascension's defence needs

A hypothetical discovery of large platinum and rhodium deposits on Ascension Island changes the importance of an existing territorial risk. The island remains in the same exposed Atlantic position, but a valuable new source of material would make its security more consequential. In the example, Britain remains responsible for defence while the territory manages domestic affairs. The proposed response is to increase the South Atlantic escort presence, potentially keeping an additional ship near Ascension. The discovery is an imagined planning scenario.
