PUR's "Julimar Discovery" in Calingiri East?, page-1594

Really good find Pensive.
I am no geo either, but it all sounds very familiar.
Great for the whole zone, not just only PUR.
Add the facts in this paper to the first hand experience of Corryst finding igneous/volcanic rocks in the area and it makes for a compelling argument of the possibility of sulfide droplets, settling in magma chambers to form massive or disseminated sulfide ores, depending on the amount of silica liquid which has also settled in the chamber.
The Geos are all probably rolling their eyes at us amateurs!!!!
My favourite part-

Because the density of sulfide liquid is higher than that of silicate liquid, the segregated sulfide droplets tend to settle down to the lower parts of the magma chamber. In particular, when sulfide immiscibility and segregation occurred relatively earlier than the crystallization of the silicates, the sulfide droplets could be concentrated at the base of the magma chamber to form massive or semi-massive ores. In contrast, if sulfide segregation and silicate crystallization occurred at the same time, they would settle down together and form disseminated sulfide ores.In a horizontal magma conduit, the settled sulfides could form large and continuous ore layers at the bases of the magma chamber, such as the ore-bearing intrusions in the Noril’sk area (Fig. 2) and in the Yangliuping area, Sichuan (Fig. 4). However, in a magma conduit with a complicated shape within metamorphic rocks, the sulfides concentrate in those places where the conduit became widened and flat, or at the entry of a new magma chamber, such as in the case of the Voisey’s Bay deposit (Li et al., 2000, Naldrett, 1997). Sometimes, the sulfide-silicate mushes could move under structural compression to form new ore bodies of unusual shape and lithologic distribution. For instance, the Jinchuan No. 1 ore body is situated at the centre of Segment II (Fig. 3) (Song and Li, 2009) and the massive sulfides of the Limahe deposit are located at the lower margin of the mafic-ultramafic intrusion (Fig. 4C) (Song et al., 2008, Tao et al., 2008).
