I love the sharing of legitimate information and research so I thought I would share an informative link with a video about GPH. I have recently bought in after reading quite a few post and more importantly researching the update information.
The highlights about the below are in regards to their fertilizer (Potash) project:
Potential of 75-100,000 tonnes per year
Potentially 23 million tonnes in total
Full estimate due in June
Mine life expectancy life is very long
This product is a premium fertilizer used by farmers in Australia. Recovery is cheap considering the life of the operation.
