Franking of RRL divs

With the release dates of annual reports rapidly approaching,
and possible announcement of divs, it's worth considering whether
the various goldies had franking credits on divs in the past.
I found some data in a recent stock analyst's newsletter,
listed below for some of the larger Au producers on ASX
with MC's between $1-10b. This data may be slightly out of date,
so please DYOR.
Note that RRL is one of the few that had 100% franked divs
(but not a guarantee that the next divs will be 100% franked of course !)
