I don't know whether or not this is a bug, but things aren't working the way I believe they should, nor according to the 'pedia. What happens is I found a couple of new cities on another landmass, one of which is directly on some marble. I check the city and cleary have the marble resource available to me: http://img214.imageshack.us/img214/4114/59668797ic5.jpg I then turn these two cities into a colony, but when I go to the trade screen I'm unable to ask my new vassal for the marble. http://img165.imageshack.us/img165/892/69155795qw0.jpg The 'pedia tells me that I should still have access to all resources of the colony, but that doesn't appear to be the case. I'm running v3.13 and using v1.07 of the unofficial patch.
