Forbes estimates Alberto Bailleres Gonzalez and his family's fortune at $16.5 billion, ranking him as the 38th richest person in the world.
He is Mexico's third richest man behind Carlos Slim ($69 billion strong mobile phone king and richest man in the world) and retail and media mogul Ricardo Salinas Pliego whose pesos stack up to 17.4 billion USD.
Gonzalez's wealth is largely thanks to his 69% shareholding in Industrias Penoles, which controls Fresnillo, the world's largest primary silver mining company and a number of other silver and gold mines in Latin America.
The Gonzales family has added more than $10 billion to their stash since 2009 and it is not likely that they will stop accumulating cash – Penoles this month announced a 63% bump in 2011 profits to $1.5 billion.
Forbes says the 80-year old who sits on a number of boards including a Coca-Cola distributor is a fan of bullfighting.
