Thanks for posting. We will have to get this cleared up.
I understood from a previous conversation with Brian Maher that at the time he spoke (2 weeks ago) the GM was seen as 9 km, of which 1 km was SGX's. So 8 km KXL and 1 km SGX. That was the story I got.
Of course, that was before knowing anything about how long the Golden Extension is. Maher later suggested he figured 1.6km.
It could well be 2, 3, or 4 km long - the only limitation is that the on-the-ground prospecting hasn't been done.
I do believe the 8 km KXL figure, personally, and the SGX extent is open and unknown. I would figure on 2.5, and if it's 4 km long then great!
We still need to get in there with photoshop and all.
