A <Reward> child pays out for that zone. type 6 with a def pays that item def, type 1 pays credits, type 3 pays the third currency bucket. Raise value for a richer zone, change def to pay a different item. 
<Zone id="132" name="Jericho_IsidMiningsite3" levelName="asteroids_wild_rock_08_c_ow" minAccountRank="12" maxPlayers="24" civilianZone="1">
  <Reward type="6" value="1500" def="AlienCompositeAlloy" />
</Zone>
<Zone id="134" name="Jericho_IsidStation3" levelName="asteroids_wild_rock_09_c_ow" minAccountRank="12" maxPlayers="24" civilianZone="1">
  <Reward type="1" value="40000000" />
</Zone>
type 6 needs a valid def name or the reward fails. Only change type/value/def, never invent a new type number.
Additional Notes: 

Reward def names must exist as item defs.
