Yellow to yellowish green Jahnsite to about 0.5mm in clusters to 3mm. It is associated with dark green to rusty red Mitridatite. If I had to guess it is Jahnsite-(CaMnMg).

Yellow Jahnsite crystals to about 0.5mm with good coverage. There may be two different types of Jahnsite as another is more green than yellow, if you can go by color. Other minerals include dark red Rockbridgeite and dark green Mitridatite.

This is one of the best specimens of Montgomeryite I have seen. The crystals are well defined, distinct and vibrant. Both sides are covered with the bright red crystals. Red Montgomeryite is only found at two localities: the Tip Top mine and the White Elephant in the Black mining Hills of Dakota (to quote the Beatle song Rocky Racoon). The White Elephant Montgomeryite, doesn't compare to the Tip Top. There is a little black Robertsite on the specimen (forth and fifth photos).
