Sadly, it's a limitation of the mission system that doesn't include items harvested by a ship as having been mined by the player.

You should be able to do Zascosium/Erestrum/Gold/Platinum by mining asteroids with an Enhanced Laser Drill fairly easily.
Either way, the class system is meant to be a grind.

Doubled mining calculations would be a bug with the game. No way to fix it.

Had to park my CV with mining turret (!) next to a sathium asteroid, while mining with the laser hand drill for an hour(!)... feels just really stupid.
Too bad the mission mechanics don't allow CV/SV mining to count. Maybe you could atleast add some story about it... "to really get a feel for this type of ore you have to mine by hand"... or something like that.

The PDA text for mission 4 recommends the use of a tool turret for salvaging the advanced materials. So, CV/SV salvaging works properly?

About the double mining calculations: It seems that every ore has a specific density, maybe this could be used as a common ground to add correct ore numbers? So, instead of "mine 4k advanced ore" it could read "mine 4k m^3" or "mine 4 tons".

@vermillion i am doing the Engineer as subclass and got to last lvl and need to salvage 16k from ZIRAX main POI but no matter whut poi i salvage not even 1 of them seems to count while my friend doing same mission as primary does get proggress on same pois

is there diffrent POI that secundary engineer needs ?
is it bugged ??
as i cant change it after picking it this kida makes me sad :(

That one mission is bugged and will be fixed in the next update.

thanks for fast response was starting ro question my sanity <3

Bit of a necro, but the game also counts ore dropped and picked back up as "mined by hand", regardless of where it came from

The new 1.7 Engineer missions no longer require mining. You just need to be the first to discover X number of ore deposit Y.

Is the bug with Engineer warp bonus being applied to the navigation data bonus be fixed in RE 1.7?
In RE 1.6, if you would do the Engineer class quest first, then you can apply less navdata (40x with 5x class quests, as one quest level counts as 2x navdata)

Yes, in RE you can now stack the Engineer's warp bonus with navigation data.
