The table being inaccurate isn't even the important part you need to focus on.

What the table doesn't tell you is that grade is only one aspect of a deposit depth, thickness, recoveries, strip, but most important factor that is always over looked is consistency along strike.

So in my opinion an isolated 4% zinc hit is not only low grade, it's unattractive because of lack of consistency in the intersects.

Now you grades table is laughable not only because it neglects depth, thickness, recoveries, strip, consistency, but because it is so far off the mark.

How can I tell show me a primary silver deposit running 50 g/t material, by my calculation no silver deposit in the world is break even under 90 g/t, that is break even not profitable.

What about cobalt 1%-2%, is there 1 % cobalt deposit in existence? I have never even seen a 1% cobalt drill hole, how is that medium grade, your chart is wayyyyyyyyyyyyyyyyyy off.

How do I know from years of experience and research, I don't look at tables, I study existing mines and historical results.

I think the table is about right by my experience and just looking up a few things on the net.

Grades are just that - the concentration of the deposit - so 1cm at 11% is high grade just as 100m at 11% is. Grade is just one aspect of viability of a mine, along with thickness & extent, depth & nature of overburden (e.g. Sand vs mud vs granite etc), water table, explosive gasses, local politics, access to port/rail, local wages, taxes etc etc. If the deep stuff is viable then with an existing operation with all transport, processing, offtake etc already in place even a medium grade small deposit close to the surface will add value and be mined as part of the entire resource.

Zinc is usually found with lead and often also silver and the combined concentrations make it viable. 3% zinc with >2% lead is viable close to the surface and silver, copper, or gold which are most commonly associated add to viability.
