Hi Raxfactor!
Prill splits are quite different between different miners. It depends very much on the deposit being mined - in the Bushveld there are three main sources of ore - the Merensky reef, the Platreef, and the UG2. Additionally, there are major PGM deposits in Russia, Zimbabwe (the Great Dyke), and Canada. Of these, the UG2 reef (which THS and SLP are working) is by far the richest in rhodium (and also iridium and ruthenium). The rhodium content can be up to 10% in the UG2, whereas it is half that or less in other South African PGM deposits, and even less in the Russian, Zimbabwean and Canadian resources. If you go to the latest Heraeus report, there is a good article on precisely this.
But yes, it is hard for the PGM miners to increase rhodium supply by very much in the short term. Some of the majors do have plans to expand production by reopening old shafts etc., but these ounces will take years to come online.
As for substitution, I know that (palladium dominant miner) Sibanye have touted this theoretically, but I haven't seen much evidence of it in real world terms. Amplats spend quite a lot of money on developing new blue sky technologies which involve the use of PGMs (e.g. using it as the cathode in lithium batteries), but I'm not aware of them being involved in any attempt to substitute out rhodium in catalytic converters.
My outtake is the Seeking Alpha article is way off the mark because the writer confuses the popping of a speculative investment bubble with a genuine, persistent, chronic deficit caused by undersupply and (legally mandated) over demand. As far as I know, nobody is hoarding rhodium or trying to put "a corner" on the market, as the Hunt Brothers famously tried and failed to do with silver in the 1970s. There is no above the ground supply being kept in a bank vault which will suddenly be released onto the market as the result of a disastrous margin call. Of course the rhodium price will drift up and down, but (IMO) this definitely ain't a bubble - it won't suddenly go pop.
