X-ray analysis first identified the species from this occurrence, where it is associated with chalcocite, lavendulan and conichalcite.
In the small group of specimens offered at Munich, attikaite may be seen (under magnification) as pale blue-green crystals and spherical aggregates on mixed jarosite/"limonite" matrix, with microcrystals of conichalcite and arsenocrandallite.

Juanitaite occurs at one occurrence as square crystal plates with rounded corners in sheaflike subparallel aggregates and rosettes associated with conichalcite and mixite, scattered over fracture surfaces on limonitic matrix, and in another occurrence with connellite, tyrolite and azurite on quartz.
