Not that long ago, AUD gold price was around $2500,
ASIC avg for the Aussie miners was somewhere close to $1300-$1400.
There was a healthy $1000 margin.
Now ASIC for your avg miner is somewhere around $2000. Actually, probably lower than that somewhat.
Once again , they will be enjoying about $1000 margin.
The big difference is, the SP of Australian gold miners were 50-100% higher than they are now.
