Bonjour Jim!
'Des copines' is simply used to describe female friends but usually has the inference that they be school friends. However, sometimes it can be used for colleagues as well but as you pointed out it is used for younger women.
For example: Elle va manger avec ses copines. She is going to eat with her friends.
I hope this helps somewhat.
