Resource, Reserve, Ore, Grade, Volume and Value

World Diamond Resource is summarized as all the diamond in the crust of the earth with current or future value.  These include known deposits and yet to be found deposits.

Current Diamond Reserve is a stockpile in the ground which is geologically suitable for investment mining.

A Diamond Ore is a mineral deposit, such as a kimberlite occurrence, which is currently considered to be economically worth mining the economic content such as a diamond.

The Grade of the deposit assessed is the weight of the diamonds contained within a given quantity of ore deposit. The number of carats per tones of ore; that is the deposit rock such as gravel or kimberlite.

The Volume in terms of the diamond deposit is the quantity in terms of weight.

The Value of the diamond is the economic worth of the stones. The diamonds should be of high value, whatever the grade of the deposit.  A low-grade deposit with large, high value stones may make the site worth developing.
