Franking of SFR divs

With the release dates of annual reports rapidly approaching,
and possible announcement of divs, it's worth considering whether
the various gold miners or gold/copper miners 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 mid-cap Au producers on ASX
with MC's around $1b and below. This data may be slightly out of date,
so please DYOR.
Note that SFR is one of the few miners that had 100% franked divs
(but not a guarantee that the next divs will be 100% franked of course !)

Miner....Market Cap ($b)....%Franking

GOR.........1.65...........0
RSG.........1.47...........0
WGX.......1.01............0
SFR.........0.93........100
WAF........0.89...........0
BGL.........0.72...........0
AMI.........0.49........100
TBR.........0.39.......100
PNR.........0.32...........0
CDV.........0.39...........0
DCN.........0.18...........0

Another reason why SFR is looking like a winner, IMO.

All IMHO, DYOR
