Can't see if the smaller hammer mill on pilot scale were producing more that 40g/tonne on test samples, how can a bigger 25 T/hr mill can produce less than 8-10g/tonne? As per few gurus in OGX forum?

Remember:
- Principle and application doesn't change in engineering process unless the product is really low grade.
- Commissioning is a very important phase in a project life cycle which impacts a lot in life cycle cost and operation of any project. If OGX takes time to do it we have to wait and watch.
