Personally, I think that "a friend of mine" is slightly less intimate, it implies that you have a lot of friends and this is just one of them, whereas "my friend" sounds like a closer relationship. However, a lot would depend on the context.
"사견으로는 a friend of mine 은 쬐끔 덜 친근한 감이 있으며, 알고있는 많은 친구 중의 한 사람이라는
의미인 반면 my friend 는 보다 가까운 관계로 들린다. 그러나 문맥에 따라 많이 좌우된다."
그러니까 의미에 있어서 큰 차이는 없는데 my friend 가 a friend of mine 보다 좀 더 친근감이
있는 모양입니다. 그러나 항상 꼭이 이틀에 끼워서 생각할 것은 아니고 문맥의 전후관계에 따라
거이 같은 의미로 쓰일 수 있다는 말이 되겠습니다.
아래 M 씨의 예를 다소 변형한 다음 예를 참고 하세요.
My friend and I went to watch a movie called "Gone with the wind"
내 친구와 나는 "바람과 함께 사라지다" 라는 영화를 보러갔다.
I was told by a friend of mine that the movie called "Gone with the wind" was a very good movie.
내 한 친구에게서 들었는데 바람과 함께 사라지다라는 영화가 아주 훌륭한 영화라던데.
몇 사람한테서 거의 비슷한 대답을 얻었는데 문맥에 따라 다르긴 하지만 기본적으로 my friend 쪽이
좀 더 친근한 관계라는 데는 이견이 없던 것 같아요.

What is the exact difference in meaning between my friend and a friend of mine?
Which describes more intimate friendship, my friend or a friend of mine? Your kind answer would be very much appreciated.
J 의 대답
I would say "my friend" implies a more intimate relationship because it leaves open the possibility that s/he is your one and only friend. If you say "a friend of mine", the listener may interpret it as one friend our of a collection of many, one who has no special significance to you. Others will contribute.

I think that "my friend" is the more intimate.
"A friend of mine" implies that you have more than one friend (I hope!) - but does not suggest that any one of them is in any way "special".
"My friend", on the other hand, suggests that the friend is being singled-out - the emphasis is on the relationship, rather than the number. The adjective is used to show "ownership" in some cases - "my car" - in this case, of course, it serves to emphasize the closeness of the relationship.
"My friends" gives the same impression - these people are distinguished from "aquaintances" or "collegues".
Grammatically, there"s not a lot of difference - "mine" is a possesive pronoun and "my" is a possesive adjective - both tell us about the relationship, but in a different way.
Just my opinion, others may disagree.

"They mean the same thing but, in terms of useage, "my friend" is generally more intimate and specific, "a friend of mine", slightly more distant and general. Be guided by context.
"My friend and I went to Scotland on a climbing holiday."
"I was told by a friend of mine that Scotland was a great place for rock-climbing."
Used vocatively, "My friend" is the more natural of the two. "My friend, you are quite right!" rather than " Friend of mine, you are quite right!"
