, simplotite and straczekite were found a few meters away.
Slightly larger clusters of minyulite, associated with sincosite
, were discovered at the Ross Hannibal mine, South Dakota (Loomis, 1999), where about 150 flats of material were collected.
Relationship to other species: It is the barium-dominant analogue of sincosite
whose formula probably should be changed from Ca[[V.
The sincosite occurs as beautiful tabular microcrystals, possibly the best ever found worldwide; and the associated mineral, minyulite, is new to South Dakota.
Knowing that sincosite occurred at the Ross Hannibal, my grade control engineer, Bob Fox, and I made it a point (which was our job
The day finally came when we found a small crystal of sincosite in an isolated area 6 meters below the area we had noted earlier that month.
Then we would carefully pry open the rock and discover beautiful clusters of sincosite and sprays of minyulite lining the tight vugs in the rock.
By mid-April the small pit in the Ross Hannibal mine was flooded by snow melt and the sincosite was completely submerged.

Among those identified are burangaite (second world occurrence), corderoite, fervanite, fluellite, hewettite, heyite, kazakhstanite, mandarinoite, richellite, schubuelite (second world occurrence), sincosite, tinticite (in crystals
Micaceous cleavages of sincosite to 4 mm have been identified as thin fracture fillings within altered siltstone from the lower levels of the pit.
