Dear Rock,
About the occurence of Alabandite in Garpenberg Norra;
The associated minerals together with the alabandite crystals on calcite crystals are pyrrhotite, asphaltum, pyrite(?), and cubanite but NOT rambergite. As far as I know- most of this material came from deep levels~800 m (my own selfcollected are from 790).
Rambergite occurs in small cavities together with fluorite, apofyllite, calcite, barite, sphalerite, galena, samsonite, pyrargyrite, pyrrhotite and small amounts of freibergite. ( transl from summary descr: [www.nrm.se]). The 2 Rambergite crystals I have occur in a diopside-rhodo skarn.
The phrase "and the management put some of the material out on the dump for collectors to collect" is somewhat imprecise. The dumps was created as an intermediate storage for the mine, not intended for collectors but the management did allow collecting if one asked for permission.
Best regards
Aksel

Alabandite twinned with spinel law.
3 samples from Uchucchacua Mine, Peru (in my twinned crystals collection)

The small black xls on the lead Alabandite photo are manganoquadratite [rruff.info]
[www.mindat.org]
There's a good story about this specimen. I'll try to get permission to tell it
