It would be hard to believe that Spain will get 100% of this treasure just because they claim it was one of their Spanish galleons.
The treasure should be divided in 3 parts.
30% for Odyssey for recovery and finding the treasure
50% for Peru/Bolivia
20% for Spain
If Spain wants to play fair they should pay reparations to Peru/Bolivia for the millions of indigineous people that died mining the silver at Potosi!
Here are some historical facts about the silver that was extracted from Peru/Bolivia during the Spanish colonial era.
"Around two billion ounces of silver were extracted from the city’s Cerro Rico (Rich Mountain) during the Spanish colonial era. Cerro Rico silver paved Potosi’s streets, fuelled the European Renaissance and helped fund the “Invincible Armada”, the Spanish fleet that sailed against Elizabethan England in 1588.
In 1572, in colonial times, Spanish Viceroy Francisco de Toledo created a system of forced labour called “la mita”. Every seven years, for a period of four months, all males between 18 and 50 were ordered to work in the mines. They were paid a pittance and rarely saw the light of day. Eighty per cent of the male population of the 16 provinces of the viceroyalty of Peru died in these conditions. “Every peso coin minted in Potosi has cost the life of 10 Indians who have died in the depths of the mines,” wrote Fray Antonio de la Calancha in 1638.
It is from Potosí that most of the silver shipped through the Spanish Main came. According to official records, 45,000 tons of pure silver were mined from Cerro Rico from 1556 to 1783. Of this total, 7,000 tons went to the Spanish monarchy. Indian labour, forced by Francisco de Toledo, Count of Oropesa through the traditional Incan mita institution of contributed labor, came to die by the thousands, not simply from exposure and brutal labor, but by mercury poisoning: in the patio process the silver-ore, having been crushed to powder by hydraulic machinery, was cold-mixed with mercury and trodden to an amalgam by the native workers with their bare feet. [2] The mercury was then driven off by heating, producing deadly vapors.
To compensate for the diminishing indigenous labor force, the colonists made a request in 1608 to the Crown in Madrid to begin allowing for the importation of 1500 to 2000 African slaves per year. An estimated total of 30,000 African slaves were taken to Potosí throughout the colonial era. African slaves were also forced to work in the Casa de la Moneda as acémilas humanas (human mules). Since mules would die after couple of months pushing the mills, the colonists replaced the four mules with twenty African slaves. (Angola Maconde 1999)
In 1672, a mint was established to coin silver and water reservoirs were built to fulfill the growing population's needs. At that time more than eighty six churches were built and the city's population increased to nearly 200,000, making it one of the largest and wealthiest cities in Latin America and in the world.
After 1800 the silver mines became depleted, making tin the main product. This eventually led to a slow economic decline. Still, the mountain continues to be mined for silver to this day. Due to poor worker conditions (lack of protective equipment from the constant inhalation of dust), the miners still have a short life expectancy with most of them contracting silicosis and dying around 40 years of age.
It is estimated that, in the past years of indigenous labour, roughly 8 million Indians died, "eaten" by the Rich Hill."
