Limestone, Uranium and the Matai islands

In class because we are studying sustainability MrWoody has "discovered" a group of islands of the coast of Raglan and named them the Matai islands (which I don't understand as the islands are not in, or in the area surrounding, Matai bay - they are in Raglan). Each island has two natural resources and on our classes island we have Limestone and Uranium if you know anything we could do with them please comment here
