Another example of a massive deposit of microscopic gold. Just the 2nd biggest gold mine in the world.

Pueblo Viejo's global resource is about about 30Moz @ 3g/t of gold and 150 Moz of silver and a projected mine life of more than 20 years.

The Pueblo Viejo ore is refractory and consists primarily of gold and silver intimately associated with pyrite that occurs as encapsulated sub-micron particles and in solid solution.
