Sorry to repeat myself if I have , can remember where I posted my corps mining adventure.
Anyway we went mining to try it out , we picked a ganker known sys , broadcast in local that belt one was under our protection and mined away, after about an hour and a half combat probes were spotted and reds in local.
Now that should have been the time for us to leave , as it was our numbers had started to diminish, we don’t have what it takes to be miners 
Anyway they attacked , our Ew burst frig fired off its Ew bomb and moved away from the gankers after taking heavy damage , our barge sent out it’s combat drones and killed a ganker that was floundering after losing its lock.
So the gankers failed , we did end up losing our Ew burst frig because it hit an NPC miner with its blast and their defence fleet warped in later and killed it .
(Just out of interest can you fight the NPC miners combat fleet , they didn’t seem very effective taking a long time to kill a frig )
So in the end we mined we made isk to cover our frig loss and isk in the bank , I believe what we did was PvP and mined , only one that had very little to do was our burst pilot sitting cloaked watching local and d-scan and then had 15 seconds of fun.
Like I previously wrote, the gank seemed a bit weak and and half-hearted , maybe being cockie thinking they could tak us with so few ships, or knowing we were baiting just testing what we had planned.
So from now on we will be covering mining ops in cloaked burst ship and trying to get miners to fit their ships to survive a gank better , you will never know we are there
