What are the rules for XP/gold gained, especially for mission requirements?

If the mission is to mine Morkite, and you get more Morkite after meeting the quota - does that net gold, XP, or both? Is it reduced?

What about Nitra, in general? Does mining more give any benefit if you don't really need it for resupplys?

Bittergems only give XP and cannot be used in crafting, right? The same with the "error block" mineral?

What about for secondary objectives like Boolo cap? Does getting more get anything?

• Primary and secondary resources each give a small amount of xp each according to the wiki and kinda confirmed by a moderator on the steam forum, though I don't know how reliable that is. I'm pretty sure I've noticed it before but I'll need to test it to be 100% sure.

  • Morkite, hollomite, dystrum : 1 xp each
  • Aquarq : 25 xp each
  • Fossils, apoca bloom, boolo cap: 3 xp each
  • Crafting materials are worth 2 xp each
  • Other items are worth some XP but you can't mine more than the objective

• Nitra doesn't give any rewards and is lost after a mission ends*

• Bitter gems only give some addition credits (like compressed gold).
• Error cubes only give an additional 2000 xp*

*Update 25
This update will add Deep Dive missions which consist of 3 missions in a row. Nitra will be kept between these missions. It has also been hinted that Error cubes will have a use.

I did two 1/1 mining missions with booloo caps, not touching any extra minerals. In one I collected 206 morktite and got 812 xp for minerals, in the other I collected 200 morkite and got 800 xp for minerals. With the +100% bonus from hasard 4 that matches right up. Here's a pic for more details: I'm not sure how exactly the total is calculated though.
