Mitochondrial genomes are circular. So, there must only be one replicon (which means there is one ori, and no focus or foci for that matter)unlike the 30,000 oris (and replicons) that are only specific to the nuclear genome, correct?

Yes, a mitochondrial genome has only one origin of replication (like a bacterial genome). It would have one replicon, and you are correct that the 20,000-30,000 oris are a feature of the nuclear genome.
