About the Puerto Rico project: The Puerto Rico project is a large, multitarget carbonate replacement (CRD) silverzinclead mining district that has historically produced approximately one million tonnes of shallow, highgrade, directshipping ore. There has been no modern exploration or drilling carried out at Puerto Rico.
Puerto Rico Mining The estimated value of nonfuel mineral commodities produced in Puerto Rico was million in 1995, excluding the value of crushed stone, which accounts for approximately 30% of the commonwealth''s mineral value and is the island''s 2nd leading mineral commodity.

The most commonly listed primary commodities in Puerto Rico mines are Copper, Iron, and Gold . At the time these mines were surveyed, 150 mines in Puerto Rico were observed to have ore mineralization in an outcrop, shallow pit, or isolated drill holeknown as an occurance mine. 1 Puerto Rico has 12 prospect mines. 2 18 mines were in production at the time the data was entered into USGS records.
Three historic mines comprise the project: the Puerto Rico Mine, the San Jose Mine, and the Zaragoza Mine. About the Puerto Rico Mine (PRM): The PRM hosts approximately 650m of underground drifts and stopes over three levels that span a vertical extent of 60m and cover a horizontal extent of approximately 200m (strike) by 30m (width) in a northwesterly direction.
The Rio Caliente Gold Mine is near Barranquitas, Puerto Rico. The Rio Caliente Gold Mine was closed at the time of data entry with no known plans to reopen. The ore mined is composed of gold. Site

Based on a cutoff of percent Ni, the reserves were inferred to be million short tons with an average nickel content of percent. The enriched zones average in thickness from ft ( m) to 51 ft ( m), with a mean of about feet (6 m) (Heidenreich and Reynolds, 1959).
Gold mining was not resumed in Puerto Rico until 1828, when a mine was once again established in the Central Highlands. The first gold deposits worked by the Spaniards were the placer gold deposits. These placer deposits are associated with the major rivers that drain north from the Central Highlands, and were the easiest deposits to mine.

Different types of minerals can be found in Puerto Rico such as gold, copper, molybdenum, and silver. Despite the presence of valuable metal minerals in Puerto Rico, the deposits are not considered economically viable. A study carried out in 1998 estimated that the value of Puerto Rico''s nonfuel minerals was approximately 252 million.
