I am not convinced. That is, I am not say I am 100% not buying it, I am about 90% not buying it.
Why use a missile to lay sea mines? Why not just fire the missiles at ships? Maybe because of night time targeting issues against a moving object ?
Anyway, the rocket system Iran uses for sea mines is the Fajr-5 apparently. They done a propaganda claim that they could do it in Jan 2025. Details here

That looks to me like internal propaganda. As in " see what we can do now" sort of thing. And sure, as a last gasp thing, it makes sense.
But look at the size of the rocket. It's pretty big (long). And it would have to be, because sea mines are heavy. This rocket apparently has a range of 75 Km with a 178 Kg payload. That would work. But that is a big old truck setup there. It's not a man portable short range coastal anti ship missile that can be hidden in a shed.
I think the main thing is that any mines this lays would likely be free floating, not placed and tethered. Therefore they would be indiscriminate. I come to that conclusion from looking at this site here that has Iranian mines.

See the size of the moored contact mine and the bottom influence mine. Now look at how slender the rocket is in my first link. For sure a very small moored contact mine would fit. But that would be sort of pointless, because that would mean the explosive charge would be too small. It would be nuisance value perhaps ?
And that takes me back to an earlier post. That Iran have been using drones against ships. For nuisance value. That is, they appear to have not tried to actually sink ships.
Could Iran sink a ship ? Sure, just fire a couple of those Fajr-5 missiles at one.
Also, just another thought. Using a missile to deploy a moored mine. A bit pointless in that with Reapers overhead and radar, people will know where it lands. Compare that to a fishing trawler style boat to deploy them. The boat can just sail through dropping them overboard. No ballistic trajectory, and no big splash.
There is also the technical bits about plane v rocket deployed mines. Velocity of impact on the water v terminal velocity when dropping from a low altitude plane.
Oh, just remembered. Acoustic sensors. As in microphones. The whole area will be well covered with them. If a Tuna farts in the SoH. some person with headphones on will know about it.
And nope, I have no idea if the SoH has Tuna. Nor do I know if they fart.
