[Heber J. Grant]
In your letter of August 18 you make inquiry regarding John H. Koyle and the 'Koyle' mine.
Koyle is not a bishop in the Church and has not been for many years. The 'Koyle Dream' mine has been mining for gold for some thirty-odd years, as I remember, but has never found any gold. I have talked with expert mining men regarding the mine, and they tell me there has never been any ore in it worthy of the expenditure of any money in a search for gold. I have understood that they abandoned some of their operations, and that Koyle received new revelations that they should start in a new direction.
I have never seen the mine, have merely had the location of the mine pointed out to me. The Church has frequently warned its members against investing in 'ream' mines.
... The 'Koyle' mine is a very splendid institution to let alone, in my judgment.
