Even though I like the Prospect, I suggest you use an Endurance. For maximum yield you can have mining drones with you and combat drones for some self-defense.
The Endurance doesn’t have the covert ops cloak but you can move with the agility and speed of a small frigate - 500m/s while cloaked.
I used to mine in dangerous territory for hours. All the nice ABC ore for my taking and whenever someone entered the system, I warped to a ping and hit the cloak button.
You will not fine any Endurance on my losses and this one time I was just joking around with the dramiel that died totally by accident because obviously a mining ship is not match for a dramiel.
