For starters you have 389m shares fully diluted (who isn't going to convert 15c options?) and you own 50% of the project. That makes Mt Holland currently valued at $482m vs AJM at $239m or essentially double.
The contained lithium isn't that important. AJM have enough resource to last 10 years even at their projected doubling of output to 3Mtpa.
How many of you are still going to be around holding in 10 years time?
