Cheers Metallica, hopefully I won't lose all of my money. But to explain it to those in the cheap seats. As the drilling becomes more closely spaced, the reliability of the results increases. The underlying geology can only be estimated by drilling cores into the ground.

Geologists use the drilling cores to estimate the amount of material contained within an area. This estimate is in accordance with certain rules adhered to by companies on the ASX and tend to be known colloquially as a JORC.

As the Jorc becomes more accurate it moves from an inferred level, to an indicated level and then to a measured level. This is similar to moving from a standard def picture on your TV to high def. More points on the screen improves the picture. More drill holes improves the reliability of the estimates. If you didn't know that JORC can be written as a "measured" level then you might want to rethink your investment strategy and stick to the blue chips.
