Anyone else having trouble getting fucium?

I've been gathering in Wyveria for over an hour now. In that time I've gathered about 80 nova crystals (with geologist) and only 4 fucium ore even though the latter is supposed to be more common right?

Am I doing something wrong? I'm only gathering 6 of the patches before resetting, because it's quicker. Does fucium have a larger chance of being found in the lower half of wyveria or am I just frustratingly unlucky?
