With a group of 2,000 Spanish settlers, Ovando was left in charge of creating a permanent settlement on the island.

and other minerals. Realizing that mining would require intense labor, the majority of inhabitants chose to work as fishermen and farmers. By accepting this option, they also were exempted from paying imposed taxes, and were able to avoid the hard labor many other natives endured in mines. In time, natives from other neighboring islands were brought to Mona Island to assist with labor. After the death of Ferdinand II in 1516, ownership of the island was transferred to Cardenal Cisneros. The island changed ownership again in 1520, when Francisco de Barrionuevo became the island's new landlord. By 1524,

However, the petition was turned down and the island continued to remain politically part of Puerto Rico. In 1583, the Spanish archbishop of Puerto Rico received royal permission to bring Christianity to Mona Island. However, by this time most Taínos remaining on the island had either died or fled to mainland Puerto Rico due to repeated raiding by European (especially French) ships. From the end of the 16th century up until the mid-19th century the island was largely abandoned by the colonial authorities. It seems to have been sporadically inhabited, although records from this period are somewhat sketchy. It continued to be used as a refuge by pirates and privateers, including the notorious

The island's circumstances changed in the mid-19th century when it became the site of commercial guano mining operations. Various companies were granted licenses to extract the bat and seagull guano (a valuable fertilizer and key strategic commodity for the production of gunpowder) from the island's caves. Mining continued until 1927.
