New to the sight but not entirely new to the subject matter contained within...

Anyway,
Question is, has anyone ever heard of a theory that at certain times and dates, a beam of sunlight broken by the peak of the needle will cast through the eye? The spot it hits on the ground is to be the entrance to a mine?
I know of at least one person that claims to have used this method and actually discovered an old abandoned shaft that had been artificially filled in, and was not part of any recorded claim.
This site was later seized by the Govt, and chain link fenced in with signs and such denying entry.
Later this mine was reported to have been considerably widened for a time, and then filled in and covered over. Although noone claims to have seen anyone actually working the mine at any time.
This was based somewhere is the 70's, before my time I'm afraid...
Just wondering of the possibility of facts to this claim.
