Damage ARC using Jump mine 22k+ (solo) / ARC Raiders trial

No clue what I´m doing, never used those mines before... I tried stella earlier killing shredders and got around 19k but died just before extract so I decided to try matriarch. I´m just trying to learn some placements during the trial, I can imagine trying again and going for 30k+ but farming this is a pain....so not sure if I will.
