Well the op went very well. A big thanks to everyone who showed up!
It's looking like a total profit of about 12mil ISK, which isn't a huge amount, but for a mining op where pretty much none of us were experienced miners, is a great haul
Heres my AAR.
We mined a total of:
70k Azure Plagioclase
And some Silvery Omber, but I have no idea how much, or what happened to it.
We also had the opportunity to practice basic fleet movement on the way there - which is always an essential thing to learn. After a couple of jumps where people were figuring it out, we managed to get a perfect fleet warp, though I didnt think to take a screenshot. The actual op itself took place inside what appeared to be the burning ruins of a station, which we'd managed to locate - for some reason it was full of valuable ore. It was also full of a mysterious golden haze which made it really hard to see what was going on. We were only bothered by one other person, who tried to bait us into attacking her for a bit, then flew around salvaging the wrecks of the pirate ships we'd killed. Once we'd mined out every asteroid in the area, we moved on to an asteroid belt nearby for half an hour or so, before finishing. Everything went well, so theres not really a huge amount to improve on - the only way we could have earned more isk is if we could all fly better mining ships (and had an Orca with us). So yeah, perfect success
