Does anyone have an IMA number on those minerals??

Gunterite (IMA 2011-011)
Hughesite (IMA 2009-035a)

Gunterite is IMA 2011-001.

Hi Marco,

Sorry if I was incorrect on Gunterite as I used these references:

1) Kampf, A., Hughes, J., Marty, J., and Nash, B., 2011. Gunterite. IMA 2011-011. CNMNC Newsletter, Mineralogical Magazine, v. 75 (in press). [webcache.googleusercontent.com]
