Hawleyite



Hawleyite, a cadmium sulfide mineral, is locally rare. Bright yellow splotches of powdery material, found in 1878 in the Hamburg Mine, later part of the Franklin Mine, and reported as greenockite by Canfield (1889) and Palache (1935), are here found to be mixtures of hawleyite and sphalerite.
Hawleyite was also found by [Dunn] as a yellow powder associated with hemimorphite and sphalerite from Sterling Hill. (Dunn, 1995)
