Some 2 box detectors claim to have the ability not only to detect metals, but also to detect "voids" (aka cavities of empty space). This is done by tuning to the ground minerals, but then noticing a drop off in the threshold, which would indicate the LACK of ground (ie.: a cavity).
But in your case, you seem to be asking about "mud filled" or "clay filled". Which isn't an empty cavity. So I'd have to say ... no it won't. Unless your mud or clay were totally inert (mineral free) as opposed to the surrounding ground which was chalked full of moderate to heavy minerals, such that the machine interpreted it as a void ? But that's not a likely scenario, and the ability to interpret such differences would not be likely.
