sandminer help

Hi Sandminer,

I have been researching into Mineral Sands of late and comparing a few companies in this area.

I have read a few of your pasts and think that you are very knowledgable.

Can you answer a few questions in this field and help me with my research?

1) What is the generally accepted zircon percentage (over zircon percentage) for a mine to be deemed as viable?

2) The difference between wet and dry mining

3) What is cementation and how does it affect the operations cost

4) What are the industry acceptable standards for extraction rate?

5) How important is overburden? What are the cut-off depth that a mine can be looked at. What I mean here is if the HM is 10m below surface and if its 100m below surface ... at what stage does it become a big factor?

These are just some points I can think of at the moment. If you have any other points that you think is also important please let me know.

Thank you in advance
