Hey plough,
agree about WGX grades slowly increasing, though hopefully that will accelerate as they continue to drill (versus almost a decade of no drilling).
Regarding MEK.
Here goes - once you start reading this, I weirdly had to finish it! 
Murchison gold project feasibility study
Let me be clear, the 17 strip ratio is high, but... mostly due to Stage 5, which gets me closer to a ratio of perhaps 6-8 for the pits 1-3 (which I believe would be the main focus for WGX in the near term), which would see grades closer to 1.4g/t and that is before you include the smaller high grade deposit).
Trucking would worst case, reduce the grade to perhaps 1.2g/t, which would still make a profit in WGXs plants.
St Annes would also likely be produced from early due the higher grades, which would have a higher strip.
My guess it would cost .015g/t to truck it to WGX bluebird mill.
Hope that all helps a little!
