This document discusses sedimentary rocks, specifically limestone, found in the Philippines. It focuses on the large limestone deposit located on Guimaras Island, which covers 1,794 hectares and is estimated to contain at least 500 years worth of limestone reserves. The mining area on Guimaras Island has been approved for mining through a production sharing agreement with the Philippine government. The document also provides a brief overview of the various uses of lime, including in construction, building materials, soil treatment, and industrial processes. Students are assigned to further research and present the uses of lime in a table for a class assignment.

6. Limestone Philippines is actively looking for investors or partners to mine its limestone deposit or purchase already mined limestone for export abroad. Fortunately, most of its limestone resources are close enough to the earth's surface to allow the easier and cheaper surface quarrying. Limestone Philippines, through its parent company, Dorilag Cement Corporation (DCC), is also open to both investors and partners interested in putting up a cement plant on the island of Guimaras where limestone is abundantly available.

9. The mining area is situated in BarangaysMontpiller, Rizal, and Daragan in the Municipality of Buenavista. The mining area is also located in BarangaysBalcon, Maravilla, Rizal, Hoskyn, and Marubuan in the Municipality of Jordan. Both Municipalities are in GuimarasIsland, Philippines.
