Identity HelpUnknown #2 from Endeavour 26, Northparkes Mine, Australia

Hello !


I recently purchased several specimens of Sampleite from the Endeavour 26, Northparkes Mine, Kennedy Co., NSW, Australia. Upon closer inspection I noticed two unknowns (to me). I need some ID help.


Unknown #2: Occurs as up to 1 mm single xls or radial groupings, brown color with a slight irredescence, occurs along weathered/oxidized fracture surfaces associated with Quartz and Sampleite. To small to get hardness, streak, or HCl reaction. Photos included (sorry for the somewhat out of focus pics). Crude xl drawing incuded as .jpg file. I have seen these before but can't put my finger on it.


Thanks in advance !!
