Open at depth
To get a 3D idea of what some ore bodies look like and what "open at depth" looks like see:

The above is for demonstration purposes only, and I do not know anything about that particular company.....I just came across that page by accident and thought it was a nice illustration of what we may be looking at with further drilling. In any case the unknown possibilities of any ore body are only revealed by further drilling.
I would like to see SXL drill down at least 2,000 M as there is always a possiblility of even a third reserve as in the above.....but shall leave that to the geologists.
