Actual locality is at the Great Ring Farm, at the intersection of Great Ring Road and Route 34 in Newtown. See that mindat.org locality page for details on its rediscovery.
Described in Dana as "perfect dark brown crystals in mica-slate...sometimes to two inches in length and breadth." |

| ⓘ Formula: FeWO4 Locality: Lane's Mine (Lane's Lead and Silver Mine; Elm Street), Monroe, Fairfield County, Connecticut, USA - erroneously reported Description: Original descriptions by Silliman (1819a, 1819b, 1819c) match the pseudomorphs of ferberite after scheelite unique to Lane's Mine of Trumbull, also worked at the time by Ephraim Lane. Samples were sold and shipped to Silliman, he did not collect them. Origin was eventually cleared up by Hitchcock and Silliman (1826). |
| ⓘ Fluorapatite Formula: Ca5(PO4)3F Description: Reference provides no details, but its occurrence is very likely. |
| ⓘ Fluorite Formula: CaF2 |
| ⓘ Galena Formula: PbS Localities: Habit: grains Description: Reported by Silliman as isolated grains less than 1.5 cm scattered in quartz gangue and argentiferous. Probably not from Lane's Mine of Trumbull as galena is very scarce there. References: |
| ⓘ 'Garnet Group' Formula: X3Z2(SiO4)3 Description: References provide no details, but its occurrence is very plausible. |
| ⓘ Goslarite ? Formula: ZnSO4 · 7H2O Description: No details on the find listed in the reference, simply "Found in Monroe". |

| ⓘ Malachite Formula: Cu2(CO3)(OH)2 |
| ⓘ Marcasite Formula: FeS2 Locality: Lane's Mine (Lane's Lead and Silver Mine; Elm Street), Monroe, Fairfield County, Connecticut, USA Description: The vein is rich in marcasite (Hobbs 1901). |
| ⓘ Microcline Formula: K(AlSi3O8) Localities: Habit: subhedral Colour: tan to gray Description: Locality apparently quarried for this mineral, which is coarse-grained and has graphic granite texture, in part. |
| ⓘ Muscovite Formula: KAl2(AlSi3O10)(OH)2 Localities: Description: Reference provides no details, but its occurrence is very likely. |
| ⓘ Nickeline Formula: NiAs |

| ⓘ Scheelite Formula: Ca(WO4) Localities: References: |
| ⓘ Scorodite Formula: Fe3+AsO4 · 2H2O |
| ⓘ Formula: FeCO3 Locality: Lane's Mine (Lane's Lead and Silver Mine; Elm Street), Monroe, Fairfield County, Connecticut, USA - erroneously reported Description: Confusion with Lane's other mine in Trumbull (now Old Mine Park). |
| ⓘ Silver ? Formula: Ag |
| ⓘ Sphalerite Formula: ZnS Localities: |

| ⓘ Sulphur Formula: S8 Localities: |
| ⓘ Sylvanite ? Formula: AgAuTe4 Locality: Lane's Mine (Lane's Lead and Silver Mine; Elm Street), Monroe, Fairfield County, Connecticut, USA Description: "supposedly occurs" |
| ⓘ Formula: Te Locality: Lane's Mine (Lane's Lead and Silver Mine; Elm Street), Monroe, Fairfield County, Connecticut, USA - erroneously reported Description: A careful reading of Silliman (1819a, 1819b, 1819c) indicates the tellurium was not native but chemically extracted from ferberite, which was also not from Monroe, but from the unique ferberite after scheelite deposit in Trumbull also worked by Ephraim Lane. Their origin was cleared up by Hitchcock and Silliman (1826).
Januzzi misreads Silliman and mentions "tellurides" in his publications. Because the ferberite crystals from Lane's Mine of Trumbull have the shape of scheelite crystals (they are pseudomorphs with which he had no experience and was quite perplexed by) he thought he had a new mineral with tellurium in it. Silliman never mentions tellurides and his extraction of tellurium from ferberite has never been replicated. |
| ⓘ Topaz Formula: Al2(SiO4)(F,OH)2 Description: Probably from topaz-quartz-muscovite-fluorite veins that occur within and around Old Mine park in northern Trumbull and extend into adjacent Monroe. |
| ⓘ Formula: WO3 · H2O Locality: Lane's Mine (Lane's Lead and Silver Mine; Elm Street), Monroe, Fairfield County, Connecticut, USA - erroneously reported Description: Original descriptions by Silliman (1822) and Bowen (1822) indicate the type material was found intimately associated with both unaltered scheelite and pseudomorphs of ferberite after scheelite unique to Lane's Mine of Trumbull, also worked at the time by Ephraim Lane. Samples were sold and shipped to Silliman, he did not collect them. Origin of the ferberite and scheelite was eventually cleared up by Hitchcock and Silliman (1826). |
| ⓘ Uranophane Formula: Ca(UO2)2(SiO3OH)2 · 5H2O Description: Reference provides no details, but its occurrence is very plausible. |
| ⓘ ' Localities: Description: Original descriptions by Silliman (1819a, 1819b, 1819c) match the pseudomorphs of ferberite after scheelite unique to Lane's Mine of Trumbull (not Monroe), both places worked at the time by Ephraim Lane. Samples were sold and shipped to Silliman, he did not collect them. Origin was eventually cleared up by Hitchcock and Silliman (1826). |
