Since conichalcite doesn't seem to be listed for the area, what about strashmirite or some other copper arsenate with Ca-bearing impurity blended in? Perhaps a candidate for Raman, if there is not enough material for XRD?
Cheers,

That is what I thought at first but the habit is totally different from the other tyrolite from there and the white margins are a puzzle. Assuming it is tyrolite do you have any thoughts on why these are always surrounded by a white margin that looks crystalline whereas the interiors always look massive? Will post a picture of the entire sample later.
Hello Joel,
I think it will come down to RAMAN, not enough for XRD.
