there are two important factors:

the quality of the coal, so far they said it is better than wyoming Power basin

they are still looking for coke..canada has 10 billion coal reserve ..may be ours can be at least 10%

if the coverage is 10km x 5 km x 20meter depth (average) x 1.2 (average density of coal )= 10,000m x 5000 m x20 m x 1.2 ton = 1.2 Billion ton of coal..still needs at least one year before we can do the 43101 or enough drill holes to verify it..

I personally think that to push back to PP level may be achievable with next month good lab results and news about the finding of coal seam underneath the limestone..other than that, 5.00 is the maximum ..

my humble opinion
