The idiom I’m used to is “a gold mine of information about X,” meaning someone who’s willing and able to tell you a whole lot about X. Here’s a verifying link.

Minefield is often used figuratively to refer to something dangerous – to something that may seem harmless, but really isn’t. NOAD reads:

minefield (figurative): A subject or situation presenting unseen hazards : a minefield of technical regulations.

Besides idioms: ‘He knows just enough to be dangerous’, also used when someone has little knowledge about things, but is not very proficient. As a person, the basic knowledge can give a person a false sense of confidence that could lead to trouble.. I know a little bit about engines and I want to do something about it, so I start ripping them apart, only to find out that I’m not going to fix the engine and having trouble putting it back

together again. Minefield of information is not an established idiom; it might have been misspoken, misheard, or else it’s someone trying to say something humorous, playing off of mine of information, which is used to refer to a person and database where much valuable information can be gleaned. If that information is sometimes faulty, one might say something like:

Watch out for Wikipedia! Is it a minefield of knowledge?

The New York Times. This is a very clever quote, but not set in time. That said, it’s not entirely original, either; many people have used it

for other issues. The original text is the most complete and highly recommended for authors. And if you are using it, be sure they are both 100% original; there should be no separate meaning, regardless of creator’s use.

The expression “minefield of information” may be a reference to an Afrikaans novel, “Griet Skryf ‘n Sprokie”, by

Marita van der Vyver (apparently ” Entertaining Angels ” in English); I’m a veritable minefield of useless information (that I never know about) in German!

“Love two images”, is it still good? If so what is the second part of the image?
