What you are hearing is the anomaly of no iron in the air pocket. It is possible that 50 worms together can take a space in the soil to make a cavern that does not have the same mineralization of the surrounding soil. And maybe this is the reason you saw a signal. I really don't know the answer. But I have a hard time believing 50 worms have enough metal to show a metal signal unless the worms eat some jewelry. 
The ionization that microbes make from buried metals contains less metal than the buried metal target. If this ionization makes a halo, then the halo is not double the signal strength of the buried metal piece, it is only a fraction more than the buried metal would signal when compared to freshly buried with no ionization from microbes. The improved signal of a halo may come partly from the metal ions, and partly from the electronic activity of the microbes and chemicals working around the buried target.
I have often wondered about the signal strength of long time buried treasure. I wonder this: We hear stories of a treasure hunter digs an old coin with a strong signal, then after out of the ground, they discover the signal is smaller. After the coin is dug, it is not possible to measure how much signal is remaining in the soil around the coin, because this soil has been dug and scattered on the surface -- no longer same matrix as it was around the buried coin. What I wonder is this... Suppose you have a method to retrieve the buried coin with halo, but not disturb the surrounding soil. If you can remove the coin without disturbing the soil, then you can take second reading with your metal detector to see how much signal remains from only the soil where the coin was removed, and halo from only the soil.
This would be very good data to know, for research to understand the importance of halo contribution to treasure detection. Maybe someone can discover a way to recover a buried target without disturbing the surrounding ground with shovels. I don't see any easy way, but maybe somebody else knows a good way to test for halo.

Hi J_Player,
I know that seems impossible... but after digging that worms they sounded when their mass (were a lot) was on the coil !
Belive me it's incredible I know... and also geb stuff I've also thought is not a right explaination of the fact. Don't know why but they sounded... of course... with plant roots yes maybe was geb tuned out or something else... cause after making the holes and collected roots on the coil no sound was generated.
I don't know why that worms sounded. I noticed in same place, with a PI detector (GS4) same thing!
What to say... I don't know why it happens and just in one place till now I've noticed that strange thing happen !
In other places no... yes found many worms too but never sounded !
When I saw your post about bacteria I thought that this could be the cause... but maybe are the worms themselves... their structure...I don't know.
Anyway, it's true... and remains for me a big borderline argument
Best regards,
Max
