Metal is found quite easy on this map, since the metalic layers are close to the surface of the planet. Also, extractors cover a large ammount of ground, so only a few are required to get your economy going.
Energy isn't an issue either, since there are 5 geothermal vents on the mainland. Wind is between 7.5 and 22.5. Tidal strenght is 40. Let's get some metalmakers pumping
