Hi Stevo, some further info re SDV drilling, potential resource upgrade, etc. for those who may be interested....
GLN's first hole, shown in red, right at the lower eastern boundary of GXY tenements:
I've recreated this in perspective, looking ~East, with rough position of GLN hole indicated:
(note the stepped boundary for orientation reference between this image and the one above) 
(Also note that there is a well near the lower left of this image (at the end of the track heading west towards the yellow boundary/creek from near the "North" arrow), which is a fresh water exploration well SVWF12_20 as noted in the last image in this post - scroll down)
GXY drilling activities captured in this GLN pic from early 2019:
From April 2019:
From Q4 2018:
Prior published SDV resource/reserve estimates were based on much earlier drilling, as per revised DFS, 2016:
NOTE the hole depths.
AFAICT, the longstanding (and current) SDV resource/reserve (from way back in 2013) is based on drilling as per above, HOWEVER, in early 2019, GLN reported this from their adjacent hole to ours as per the photo above:
High-concentration brine from circa 200-400m !!
Note the hole depth.
Try and tell me that Southern SDV hole (#25 or #26?) was a duster, with GLN's results from it's adjacent well?!
AFAICT we hadn't previously drilled down in that area; this image from the Q3 2018 Posco sale announcement:
(I've added the red X to indicate the position of our well 25 (or 26?))
So far, AFAIK, we've heard crickets on the findings from this hole... and if that's hole 25, where is #26?
Imo, based on the GLN results, that has to be worth some extra polygons and an increase in the resource/reserve.
DYOR and build your own puzzle!
We've actually had the hints since 2013:
etc.
We'll surely find out soon enough in any case.
Pleasantly surprise us Simon..?
Cheers
IMO
