The Program for the Evaluation of the Mineral Potential of the Brazilian Legal Continental Shelf was created by the Inter-ministerial Commission for the Resources of the Sea, through Resolution No 004, the CIRM, of December 3, 1997.
Its main objective is to assess the overall mineral potential of the Brazilian Legal Continental Shelf (PCJB). Its specific objectives are: to characterize the physical environment of the continental shelf; assess mineral resources, identifying and detailing areas of significant mineral potential, collect basic geological information, for the integrated management of the platform and associated coastal zone; implement a digital geo-referenced database, for use by the scientific community, government agencies and Brazilian companies, propose methodologies and standards for implementing systematic and thematic surveys, and lead research activities that foster technological development and innovation, as applied to the exploration of mineral resources.
- Develop a model for geological and geophysical evaluation of mineral resources in the PC;
- Make the geological and geophysical survey of the PC, the following scales:
- 48% range of 1:1.000.000;
- 10% on the scale of 1:250.000;
- 8% on the scale of 1:100.000 and
- Characterize and classify the mineral potential of 8% of the PC.
The identification and measurement of aspects related to REMPLAC, done periodically, obey the following:
|ADMEASUREMENT||UNIT OF MEASURE||REFERENCE|

It is up to the Inter-ministerial Commission for the Resources of the Sea to oversee PROAREA's activities, through the Sub-commission of the SectorIal Plan for the Resources of the Sea.
These activities are conducted by an Executive Committee under the CIRM, coordinated by the Ministry of Mines and Energy, with participation by ministries and institutions involved with the action, with a scientific advice from the Marine Geology and Geophysics Program (PGGM). The planning and operational management are performed by Brazil 's Geological Service (MRCP).
The aforementioned Executive Committee is composed of representatives from the following institutions: Navy of Brazil (the Navy General Staff and Hydrography and Navigation Directorate), Ministry of Foreign Relations (MRE), Ministry of Science, Technology and Innovation (MCTI), Ministry of the Environment (MMA), Secretariat of the Inter-ministerial Commission for the Resources of the Sea (SECIRM), National Mineral Production Department (DNPM), Brazilian Geological Servicel (CPRM), the Petroleo Brasileiro (PETROBRAS), and the Navy's Marine Geology and Geophysics Program (PGGM).
