Floating cities with a new superconductor v2

I made a question regarding floating cities coming from a misunderstanding of this great answer.

Luckily one comment showed me how floating cities could be possible in a slightly different scenario.

Scenario:

• Floatium is a superconductor that behaves as such at 0 ºC and is found in nature.
• There is a great valley where the mountains that surround it are made of Floatium. (and the temperature is always lower than 0ºC) (I assume some lightning might fall unto those mountains to make current flow through them)
• In the middle of such valley, a city stands, floating at least 4 meters (ideally way more), on top of magnets.

Is this scenario plausible?

I'm specially interested in a couple of things:

• Can enough force be exerted unto the magnets on the city to put them afloat? Wouldn't, maybe, the weight of the city make it fall again?
• Can this be done through natural magnets?
