In my opinion, the Hart results posted today is one of the best news releases Liberty has ever delivered. Remember also that these results are only down to the 500 meter level.
Putting another crude model together based on the assumptions given, Liberty has added significantly to the production life of the mill.
265m X 275m X 4m x 3 s. grav = 875,000 tonnes 1st level
265m x 225m x 14m x 3.5 (higher grade) = 2,921,625 2nd level
Total to 500 m level = 3,795,625 tonnes
Lets be conservative and take 60% of this number which would give us 2,277,975 million tonnes.
In my estimations, the Hart numbers today give LBE a conservative 4.21 years at full production. The Hart deposit does not end here and I believe it is only going to get much better below the 500 meter level.
