Mining Ore with Ziplex Z1 Seeker at the Ice region on Arkadia

After my last mining run I log in to teh game at the spot that I left previous day. And droped few probes. And I decided to go to the nearest town to sell some stuff. And before I press T boom global 287 Lysterium Stone. My best global so far and my first in mining. Actualy I have been mining with real, not the rookie gear, 2 days only. And I was level 1 or 0 in my Mining professions. And I was ready to do one more mining run even if the return is not very good I am still going to be on proffit.
Also I found that the Arkadia starting TT Excavator is better then the Calypso starting TT Excavator. I mean you can max it faster. And now I can use it on max when I extract ores. When I gain more mining skills I will probably switch back to the Calypso extractor.
This time I went to the snow part of the Arkadia, but I don't like mining there. First half of the mining run was good, but then it all got empty and almost no claims.
