Description: "In 1921 a rich pocket of argyrodite was discovered in the “clavo Block” of the Gallofa vein. The mineral was encountered as compact masses and as magnificent simple octahedrons and sometimes with gemmy cube like calcite crystals associated with pyrargyrite, loellingite and rammelsbergite, sphalerite and quartz. Beautiful small star like little dodecahedral penetration twins were also rarely encountered." Ahlfeld & Reyes (1955)

(more information)

Description: New analysis done in 2021 (SEM, EDAX) by Joy Desor from a specimen in the collection of Elmar Lackner. Analytical data shows a Co:Ni ratio of approx 3:1 confirming Cobaltomenite. Notice the old entry because the similarity to Ahlfieldite: Much of the material called "cobaltomenite" from El Dragon was identified only by XRD and is really pink cobalt-bearing ahlfeldite. Color is a very unreliable guide, as it takes only a minor amount of Co to change the color from green to pink or purple.
