   I've not been excavating! There was a bubble on the surface   
   originally, which I scraped off with a fingernail to reveal that hole.   
   I didn't dig any further.

   It was very difficult to photograph, because the depth of field was   
   close to zero and the resistor was only millimeters from the lens   
   glass. I had to use a hand-held LED lamp for illumination, but   
   full-on, frontal illumination wasn't possible due to the proximity of   
   the subject to the lens, I'm afraid. The lighting varies because I was   
   holding the lamp by hand each time.
