Big property, So, I decided to get my calculator out:

5000 acres is 20,230,000 square meters

we drilled 11 holes for an average depth of 397 meters,

so, total volumn of the property, multiply the area by the depth of the holes is:

8,031,310,000 Cubic meters,

the total cubic meters of 4374.5 meters of drilling (assuming a 2" diameter core),

is 32.68 cubic meters,

so, we have explored (by drilling)...

0.0000000003.32% of the property.

My math could be a bit off, but no matter what, it is a very small percentage
