This mod adds a lot of new items, including (but not limited to) mining drills, solar panels, crates, long-handed inserters and ore & metal compression.
I'm not sure why, but remains don't generate on the map. Seems like it has something to do with the autoplace control being the oldest description ("peaks"). I think there was one time they appeared in 18 (I was using an island mod), but every other time they haven't. I haven't changed the autoplace control, but they do appear if I do /c game.player.surface.regenerate_entity("remains")
Do you mean alien blood?
Solidified remains are made in a Chemical Plant from alien blood which should be extracted from patches using pumpjacks (just like oil).
Look for red dots on the map.
The prototype on the map is called 'remains', so I call them that. I'm trying to figure out the circumstances :/ . I played many maps where the remains just did not generate, and I had to call for it myself. Vanilla+Napu's does spawn them, and I'm adding some other mods one-by-one to see if they cause conflict, but it's not happening.
If it spawns without a problem with just vanilla enabled it's a mod conflict with another mod adding in resources. Resources tend to fight for the right to be placed and can result in no resources of a certain type.
