Mines and Geosciences Bureau
The Mines and Geo-sciences Bureau (MGB) is a government agency of the Philippines under the Department of Environment and Natural Resources (DENR). The MGB is responsible for the conservation, management, development and use of the country's mineral resources, including those in reservations and public lands. The MGB absorbed the functions of the Bureau of Mines and Geosciences, except for line functions, which transferred mainly to DENR regional offices. MGB also absorbed the functions of the abolished Mineral Resources Development Board (MRDB), and the Gold Mining Industry Assistance Board (GMIAB). History 
MGB took charge of the administration and disposition of minerals and mineral lands during the Spanish Regime, but was abolished on July 1, 1886. It was transfigured during Gen. Emilio Aguinaldo's ruling and created four divisions of Departamento de Fomento, under the Philippine Revolutionary Republic. The Mines and Mountains Sections were also formed; the former was under the director of Industry and Agriculture, and the later was under the director of Obras Publicas (Department of Public Works & Highways). The sections were re-organised after the Americans’ arrival, resulting in the emergence of the Mining Bureau. In 1905, the Mining Bureau and the Bureau of Government Laboratories were fused under the Bureau of Science, and the Mining Bureau became the Division of Geology and Mines. In 1933, the Mineral Lands Division of the Bureau of Lands was merged with the Division of Geology and Mines, under the Bureau of Science, to form a division known as the Division of Mineral Resources under the Department of Agriculture and Commerce. After one year, it was renamed Division of Mines. With the outbreak of the Second World War, the Bureau of Mines was reconstituted under the Department of Agriculture and Commerce under Executive Order No. 1 dated January 30, 1942. In 1944, during the Puppet Philippine Republic, the Bureau of Mines shrunk again into a Division of the Department of Agriculture and Natural Resources. The revision of Commonwealth Act No. 136 in 1978 boosted it again, it was renamed Bureau of Mines and Geo-sciences Bureau. This gave it an additional function, as well as the authority to make it more responsive to the objectives of the government's minerals sector. In June 1987, the MGB was formed under Executive Order No. 192. In 1997, under DAO 97–11, the MGB implemented a full re-organisation specifically involving the establishment of two new divisions—the Mining Environment and Safety Division, and the Mine Tenement Management Division. These divisions operationalised the sustainable development principles provision of the Mining Act of 1995. Services
