How to copy vmcore file without expand it

Hello,
        When a system crash it create a vmcore of 256M size under
/usr/adm/crash like:

cd /usr/adm/crash
ls -al vmcore.0
-rw-r----- 1 root system 268427264 Dec 17 10:09 vmcore.0

but the actual space used from the disk is much smaller (about 25M) like:

du -l vmcore.0
24464 vmcore.0

It's possible to move this file to another directory without expand it to
used 256M of disk?, i.e keeping the same disk space used. I try the command
mv, cp, tar, dd, compress/uncompress without success...

Thanks, Sylvain Gagnon
