I’ve seen Talassonite and Rakovene appear around minor and major Triglavian conduits, respectively, and the rocks stay after the conduit in question is closed. What I’d like to know is how I should go about mining Bezdnacine, which only appears at World Ark proving grounds. The one time I managed to get a Procurer in the same system as an Ark, the rocks disappeared before I could mine any!
How do I get access to mineable Bezdnacine without being shot at by Triglavian ships?
Not the barges themselves, but a pair of Porpoise could be fitted to spider and keep procurers alive. One of them is fitted with mining bursts, and the other with shield bursts.
For a true spider tank, you’d need to use mining frigates with their auxiliary highs. A combination of ventures or bursts.
For the soloist - mining barges do not readily themselves to active tanks and kiting damage. You would looking at a Prospect for that style.
