The GE-SE (southeast) is the southernmost pit of 3 opened by Perien Dudley in the 1920s in search of pollucite, an extremely rare cesium mineral. All three granite pegmatite quarries are located on Hodgdon Hill in Buckfield. At the time there was demand for cesium to be used in the manufacture of vacuum (radio) tubes. Both the General Electric Company and their main rival, Westinghouse, were buyers of pollucite. Later bismuth replaced pollucite in this application, and the mining ended. Modern uses for pollucite are in the preparation of environmentally friendly drill fluids used in oil and gas well development. Cesium is also used in GPS satellites for their extremely precise atomic clocks. Modern efforts by Coromoto Minerals, LLC, have confirmed that pollucite is relatively abundant at the GE-SE. However, there is a perplexing question that comes with this occurrence. In almost all other pollucite occurrences worldwide, pollucite is associated with even larger amounts of lithium, typically in the form of lepidolite, spodumene, and petalite. These minerals appear to be absent on Hodgdon Hill. The only lithium mineral encountered at the GE-SE in any quantity has been montebrasite.

All three of the pegmatite dikes strike essentially NW. All are near vertical and relatively narrow at +/-7m'. The GE-SE pegmatite has been traced over the surface for 400 meters and measures to a depth of at least 30 meters.
