I think most of the "P" metals are ranging between 500 and 1000 US.
Palladium is a sustatute for Platinum
Most Platinum group metals come from Norilsk in Siberia, next would be S. Africa and then Sudbury. Metal is metal it all depends on how its refined and for what it is used. Let me give you an example Ferronickel is a product 80% iron 20% nickle its used to make stainless steel and is cheaper than Sinter75 also used for stainless steel but 75% nickel. Electrolitic refined nickel is sold in big shiny ingots and sells for about what the LME price is depending on contract. Nickel powerders like Inco 202 or Falco crowns are refined to a very high degree for use in batteries and super allows (using the nickel carbonel gas process , I only know of two or three plants that do this 1 in Canada 1 in Wales and 1 in Norway that produce 90% I suspect there may be other plants In Japan China Russia and USA(Oak ridge, I looked this up once and or possibly in Texas). The price of this is negotited behined closed doors. Titanium, cobalt, berilium and some of the other metals are also sold at or more often above the world price depending on grade and suply. This is why the USA keeps stratigic reservers of these many of metals incase of war, or if they are cut off from imports
Here's some number crunching....
An 8 yard bucket holds about 15 tons of ore from the Creighton "Plumb" that grades at 8% nickel $14,000 US a ton and 10% undisclosed metals (meaning the PMGs gold, silver, cobalt). I wonder how many homes I could buy for a bucket???
