I experienced similar case.
I had an image "image1.png", it had some transparent pixels.
When I did "convert image1.png image2.png", all the transparent pixels
became white and transparency information was lost.
To solve the problem I did "convert -type truecolormatte image1.png
image2.png" and I got same image in image2.png.

I have not tryed this with montage, so I am not sure if this helps your case.
