Detailed Mineral List:

Acanthite
Formula: Ag2S
Reference: Mineralogy of Michigan (2004) Heinrich & Robinson
Analcime
Formula: Na(AlSi2O6) · H2O
Habit: Trapezohedra to 2.5cm in diameter
Colour: reddish
Description: When they are associated with good copper crystals they become objects to lust after. I am sure that the best of them would bring well over a thousand dollars but without the copper association these analcimes would probably not even make this list of notable localities. Also as rare pseudomorphs after feldspar(?).
