| Basis for focus area |
Pegmatite deposits that do not fall into larger districts are within this Raymond district (Bradley and others, 2016). Also see Meyers and Stewart (1956). |

| Comments |
Resources of the Raymond district (New Hampshire) "are of no great magnitude" (Page and Larrabee, 1962, p. 1). |

| New data needs |
Mapping. |
| Geologic mapping and modeling needs |
Detailed mapping of pegmatite bodies, geophysics may not be useful for pegmatites. |
| Geophysical survey and modeling needs |
High resolution aeromagnetic and aeroradiometric coverage underway. |
| Digital elevation data needs |
Lidar is adequate. |
