The geological and tectonic framework and the mineral associations of both occurrences have been investigated in detail. Both mineralizations can be attributed to Tertiary magmatism, but were deposited in two temporally distinct periods. The older copper sulphide mineralization is structurally controlled by pre-middle Ecocene tectonics and is linked to Eocene shoshonitic volcanism. The second, younger nickel-cobalt-silver-bismuth-uranium mineralization might be attributed to a granitic magmatism linked to a Miocene phase of movement.
