Mineralogical and chemical zonations observed in massive sulfide ores from Ni-Cu-platinum group element (PGE) deposits are commonly ascribed to the fractional crystallization of monosulfide solid solution (MSS) and intermediate solid solution (ISS) from sulfide liquid. Recent studies of classic examples of zoned orebodies at Sudbury and Voisey's Bay (Canada) …
The relative abundances of the Platinum Group Elements in the massive sulphide body are similar to that of other Ni-sulphide deposits such as Sudbury and Noril'sk, but differ significantly from that of the Merensky Reef, UG-2 Reef, …
Abstract Podiform chromitites, a part of Nidar ophiolite complex from the Indus Suture Zone (ISZ), southeast Ladakh, host significant platinum-group elements (PGE) and platinum-group of minerals. These high Cr chromitites are found to be enveloped within the dunite rocks in the form of massive, semi-massive and stringers and as disseminated grains in all the …
The Cr/Fe ratio, using total Fe, varies between 1.52 and 1.61 in samples from the massive chromitite, but decreases sharply to values below 1.42 in the orthopyroxenitic foot-and hanging-wall. The massive chromitite layer records the highest platinum-group element content (717 - 945 ppb), whilst the juxtaposed chromitiferous orthopyroxenite records
Large volumes of these chromite-only-saturated melts replenishing these chambers are responsible for monomineralic layers of massive chromitites with associated platinum-group elements.
Aurora is a platinum-group element (PGE) prospect hosted in the Northern Limb of the Bushveld Complex, South Africa. It is one of only three deposits discovered in the Northern Limb so far to be hosted in the melanocratic-leucocratic gabbroic cumulates of the Main Zone of the Rustenberg Layered Suite (Aurora, Moorddrift and Waterberg T Zone deposits), rather than …

Platinum Group photo. ... Fraser said the creation of the new zone has been in the works for four-to-five years when Vancouver-based developer Platinum Group first proposed the massive project. "The developer has worked with our staff because there wasn't zoning for that much density," said Fraser. "We now have an RC zone that will allow for ...

All textural facies are characterized by typical magmatic pyrrhotite-pentlandite-chalcopyrite-(platinum group mineral) assemblages. Massive sulfides are localized in two embayments along the basal contact separated by a topographic high, grading upward to rare semimassive, laterally more continuous net-textured, and disseminated sulfides, with ...

Years ago, in a message to the Platinum Group team, our founder, Dean Bachelor, summarized a mission for the firm Meaningful Capitalism. TM In short, Dean's passion was to bring significant meaning to the stakeholders of every client Platinum worked with and to drive the economic engine – capitalism – which is the foundation of our great country.
Magmatic sulfide deposits containing nickel (Ni) and copper (Cu), with or without (±) platinum-group elements (PGE), account for approximately 60 percent of the world's nickel production. Most of the remainder of the Ni production is derived from lateritic deposits, which form by weathering of ultramafic rocks in humid tropical conditions.

Detail work on the geochemical variations in terms of major, trace and platinum-group elements (PGE) of the massive chromitites and the host ultramafic cumulate rocks of the Sukinda Massif has not been previously undertaken. In this study, we report extensive whole-rock major, trace and platinum-group element data for chromitite, serpentinite ...
An enrichment in nickel (Ni) or platinum group elements (PGE) is seldom observed in ores of the iron oxide–copper–gold (IOCG) type. This phenomenon is, however, known from a few deposits and prospects in the Carajás Mineral Province, Brazil. The Ni-PGE enrichment is explained, in part, by the spatial association of the IOCG-type ores with altered mafic …
In the case of Cu-Ni-PGE deposits, there is consensus that the fractional crystallization of MSS differentiates the IPGE and Rh from Pd and Pt, forming IPGE-Rh-Ni-rich massive ores and Pd-Pt-Cu ...
We checked and The Platinum Group is not regulated by a top-tier regulator, so you are better off avoiding it. By contrast, mid-tier regulators are like the security guards at a county fair. They do their best to keep things in order, but they don't have the same resources or strict rules as the top security at a massive festival.

The platinum-group elements (PGEs)—platinum, palladium, rhodium, ruthenium, iridium, and osmium—are metals that have similar physical and chemical properties and tend to occur together in nature. PGEs are indispensable to many industrial applications but are mined in only a few places. ... For some conduit-type orebodies with massive ores ...
The platinum group metals or PGMs are a cluster of six transition metals on the periodic table. They are noble and precious metals with chemical and physical properties similar to that of platinum and occurring in the same ore deposits. The platinum group metals are rare, durable, useful, and highly valuable. ...
All three intrusions contain massive chromite layers and because chromite is one of the first minerals to crystallize it is possible that chromite compositions could indicate the compositions of the magmas. ...

Platinum-group elements (PGE) are widely used in tracing various geological processes, such as the origin and evolution of mantle-derived silicate melts and the formation of magmatic sulfide deposits (Barnes and Ripley, 2016; Harvey and Day, 2016).Magmatic sulfide deposits, including Cu-Ni-PGE deposits and PGE deposits, are formed by the accumulation of …
