Species: ALMANDINE Locality: Ford Mine, Wilmot, NH Specimen Size: 8 cm specimen (estimate) Field Collected: Unknown Catalog No.: A Woodman Institute specimen, #600080 Notes: The Ford Mine is not listed in Morrill, nor included in the mindat.org data base. Perhaps the Ford Mine is an alternate name for one of the two garnet mines recorded for Wilmot, NH. Photo is a low effort snapshot. |

Species: ANDALUSITE var. Chiastolite Locality: Rochester, NH Specimen Size: 13 mm cross-section (estimate) Field Collected: Phillip Foster Catalog No.: A Woodman Institute specimen, #640038 Notes: Meyers and Stewart, Geology of New Hampshire, Part III Minerals and Mines, lists chiastolite from Rochester (pg. 9). This may be the Salmon Falls occurrence. Photo is a low effort snapshot. |

Species: "ARSENIC" Locality: Jackson, NH Specimen Size: 6 cm specimen (estimate) Field Collected: Unknown Catalog No.: A Woodman Institute specimen Notes: Phillip Morrill, New Hampshire Mines and Mineral Localities, lists arsenic from the Eastman Hill Tin Mines in Jackson. Meyers and Stewart, Geology of New Hampshire, Part III Minerals and Mines, (pg 11), states that for the arsenic occurrence at Jackson "it was present in thin layers in a dark blue mica schist, associated with pyrite and arsenopyrite." The luster of native arsenic is metallic, sub-metallic, dull. Color is tin-white tarnishing to dark-gray, black. A grain sample from the metallic seam on this specimen was EDS analyzed, BC461. The result was simply pyrite. Although the overall specimen has a blue hue, I would not consider it to be a mica schist. A single sample does not disprove the presence of native arsenic, but at this point I am skeptical. If an opportunity presents, I will attempt another analysis from a new sample. Photo is a low effort snapshot. |

Species: ALMANDINE - miss-labeled as Rhodonite Locality: Lost River, Benton, NH Specimen Size: 6 cm specimen (estimate) Field Collected: Unknown Catalog No.: A Woodman Institute specimen, #600077 Notes: EDS analysis, BC460, June 2022, Showed this pink vein mineral to be almandine. A similar vein of pink almandine (also analyzed) in biotite gneiss occurs in a Rt. 112 road cut in Easton, NH. When I saw this "rhodonite" I was immediately skeptical. |
