Treasure hunt rating, what does it mean?

How about the gathering %'s on maps?

p.s this is all from trees as I'm not a miner.

Could depend on your gathering gear, no?

I too have been wondering about the battle evaluation system and if/how it affects the treasure loot. I have also been trying to figure out what does affect the evaluation itself. Some people believe it depends on the map itself, but there's also factors such as # of participants and killing speed. I have always been soloing all my treasure maps (I can't get to the lv50 ones yet), and always got bronze. Then one day I joined a friend in a full party to burn through his 8 maps. I don't know if they were all peisteskin maps or not, but never once did we get less than gold rating. It really leaves you wondering.

The color of the chest and medal is predetermined by the map type. Bronze = Leather and Goat, Silver = Toad. Gold = Boar and Peiste. Your performance and number of participants has no effect on what you get. However, rewards are randomly split between participants (and not always evenly), and anything less than peiste will also split gil and tomes (piestes do not). So it is always best to do anything below a piesteskin map solo if you can, the rewards after being split for them is just not worth it.

Also, there are two "levels" of rewards for all maps - regular and triple. Triple will get you 3x tomes and gil, and usually more HQ mat rewards as well, although I do not know if things like minions are exclusive to these triple payouts.
