Just wondering if there's any "special" mat' scavving locations in the region of Colonia?
Anything like Dav's Hope, the Jameson site or any crashed Anne's etc?
Also, as I write this, I'm getting a feeling of deja vu so you'll have to excuse my senility if I've asked this before.
Broadly, no, not at that level.
The wrecked megaship in Luchtaine has a small amount of low-grade manufactured materials.
There's obviously no shortage of volcanism sites for raw materials.
Plenty of installations for data piracy for some types of high-grade data
There are the tip-off sites, some of which have cargo racks for high-grade raw or mid-grade manufactured (depending on site) which unlike volcanism can be re-logged if you really need a lot.
https://cdb.sotl.org.uk/sites#tip-off has a list (and please let me know if you find any not listed there) - but bear in mind that they're on a ~3-month rotation and only appear for 2-3 weeks at a time, so unless you have a tip-off message, you might be disappointed.
(Once visited, the next time they rotate in they'll appear on your navigation without needing to get a new tip-off, though - if you're expecting to stay a while)
