RE: RE: RE: SKP samples 199 g/t Au over 100 m at AIf someone's having trouble understanding ppb, just think of as "parts 'something' per billion parts 'something else". So, 1 cat in a billion dogs = 1ppb "cats". (that would likely be one dead cat!)
1 billion grams of earth is 1102.3113 tons (short). So, the comparable unit of measure were all used to seeing is 210g Au/1102.3113 t earth = 0.19g Au / ton.
Lipstick on a pig, indeed!
