to start with you need quite alot of peds just to get started, for that (if you dont deposit) you need to sweat, there are much help about that in this forum
to get started om mining, you get tools from the TT (Trade Terminal)
the blue one, not green/yellow/red (and not the blue box, thats storage)
then go to "tools" then "mining"
there you have
"Omegaton detectonator MD-10" for
2.4ped
"Genesis Star Earth Excavator ME/01" for
2ped
this two are used to mine
ORE, and for that you need
BOMBS (1ped=1bomb)
the bombs you find where you find these tools
"Omegaton enmatter detector ED-10" for
3ped
"Genesis Star Energy Extractor EE/01" for
2.4ped
This two are used to mine
ENMATTER, and for that you need
PROBES (1ped=2probes) the probes you find where you find these tools
so in the beginnning its quite expensive to become a miner.. but you can do it! GL
