I'm sure some of each of those has been provided. The ResourcesMission_RewardAnomaly in the MissionRewardDefs.xml shows the amount can range from 0 to 2.
The problem is that the display shown after the mission is completed seems to show only first digit. If the amount is 0.99 or lower, the display will show 0. The correct amount will be be added to your inventory.
I remember checking this by keeping track of my inventory of those 3 items and checking to see what changed when the mission was finished.
It sure would be nice if the display could be changed to show more digits so that it is obvious how much was found.
