Chlorox won't give you PtCl2 no matter what the nature of the ore is. PtCl2 is not an easy one to make from aqueous solutions Randy. Also, PtCl2 looks like rust; it's not canary yellow regardless of pH. Likewise, you won't be having any alkaline rhodium chlorides. If you think you have rhodium, add some HCl to it and then tell me the colour. I've seen lots of RhCl3 in my time, and many, many, many other PGM compounds and complexes.
I wish I had access to really nice camera equipment so that I could take photos of all the commonly encountered PGM salts so that people on this forum could see what they really look like in their pure state and not get excited over different colours of solutions.
I can see you dissolving some Ru and Os with hypochlorite, but I highly doubt you're getting platinum out it, or rhodium.
I have a book that I suggest you read. It is by Cotton and Wilkinson, two excellent chemists that I wish were still around. It will teach you wonders about coordination chemistry of the PGMs. Get the 5th Edition.

This book will help you understand why you're being fooled by other transition metals and how the PGMs really behave. It can also give some insight into how you might treat your ore if you knew what was really in it (meaning you have a real assay done by professionals, again try Ledoux).
My point is that PGMs are quite rare. Your ore may have them present, but it won't be in an easily extractable matrix nor in a form that you can just hit with sulfuric or nitric or HCl even. You won't find the PGMs forming salts (like halides, i.e. chlorides/bromides) which are soluble and amenable to wet chem extraction because those salts are UNSTABLE and unlikely to survive the heat and pressure involved in their being thrust from the mantle to the crust and our own familiar terra firma. More likely you'll find Pt as an intermetallic with elements it likes-usually metalloids like As, Te, Se, Ge but maybe C and S.
I'm not saying that your ore is barren, it just sounds like you're extracting iron and copper and other first row d-block transition metals.
Just my thoughts.
