Using the ^ prefix along with the haltdef command would
halt mIRC default text from being displayed yes.

on ^*:OP:#: {
echo -a $nick opped $opnick on #
haltdef
}

~ Edit ~
Yes I should have mentioned that but didn't think about it
until reading Mentality's post, the text will only be halted
locally (on your mIRC) and not anyone elses.
