After such a dismal ore mining run I was hoping for something better enmatter wise.  If anything though things went worse.  From 100 probes I found the following :
 
1610 oil    16.10 ped
37 Garcen   3.70 ped
297 Melchi  5.94 ped
26 Alice    1.30
 
Total:      27.04
 
My biggest run without a find was 12 probes.  
 
The decay incurred was again roughly 2 ped.
 
Total loss this run (50 ped - 2 ped decay - 27.04 tt return = 20.96).
 
Total loss so far: 54.80 ped (broken down by 20.96 + 33.84 (loss incurred on the ore mining trip)).
