For Final Fantasy XII players ..need help.?

After you leave Golmore Jungle, you should see a pair of Imperials and one of them is injured. Talk to one of them and he'll ask for a potion, so give him one. When you give him the potion, he'll offer you their chocobo, so take it. The path to the Henne Mines can only be accessed by Chocobo, it's hidden but there should be chocobo footprints near it. I can't say exactly where it is, but it's through some gr that only a chocobo can walk through.
