Based on the data, apart from the Ag grade, Rupice could easily fit the Bimodal-Mafic VMS type although Rupice's grades of Zn,Pb and Au are significantly above average for this type of deposit and its Cu grade looks below average (at this stage). The higher Zn,Pb,Ag and Au grades at Rupice (based on these statistical distributions) are a blessing and a curse, because statistically the anomalously higher grades of these elements reduce the range of potential sizes. If you look at my video the Ural type bimodal VMS deposits are very prominent in the Ural mountains of Russia (albeit they are more than 3,000km away from Bosnia....see clip below).

Looking at the Ag grades of the bimodal-mafic VMS deposits there where only 3 bimodal type VMS deposits recognised by USGS (world wide in 2010) with grades of over 312g/t Ag. I've highlighted them on the plot below. I've also marked another deposit on plot, Rey de Plata, that has a close Ag grade of 240 g/t . All 4 deposits are in Mexico. I'll post some more information, grade comparisons (ie Cu,Zn,Pb and Au grades) and ages, rock types in another post.

The problem with SEDEX is the high Au grade at Rupice and relatively high Cu grade. I need to find similar data on SEDEX. Esh
