Refining iridium Ore
If it is shown on a rock/milled ore sample, it is just non-trustworthy number. If you manage to smelt the ore and get metallic sample of iron (for example by induction furnance, in graphite crucible with silica and calcium oxide as fluxes) - and it still shows iridium, then I would get interested in further proper assaying by ICP or NiS assay But chances are low.

Endogenetic gold ores include vein and lode deposits of elemental gold in quartzite or mixtures of quartzite and various iron sulfide minerals, particularly pyrite (FeS 2) and pyrrhotite (Fe 1-x S). When present in sulfide ore bodies, the gold, although still elemental in form, is so finely disseminated that concentration by methods such as those applied to alluvial gold is impossible.
