White Mt. Metal Ore Mining District. - Hydrothermal vein deposit on a fault. Often referred to simply as the Gorham Lead mine. The mid-level adit of the complex was called the Galena King adit by the workers, and this name is sometimes still used as a name for the mine. The real name of the site is Mascot Mine. (The Mascot Mining Company, organized in 1881, first worked the deposit.)

This site is in Leadmine State Forest, owned by the State of New Hampshire. Collecting is allowed on the dumps using hand tools only. Entry into the mine itself is forbidden, the openings gated. Collectors are not allowed to dig up the mine road itself.

Reports of bornite and other primary copper minerals from this site which are not listed here have been proven to be in error by recent studies. Analysis of the rarer sulfates and carbonates was accomplished with SEM and XRD. There are still several "unknowns" being analyzed.

Detailed Mineral List:

Acanthite
Formula: Ag2S
Habit: Thorn-like habit on or near wire crystals of native silver; as micro-crystals only.
Colour: Dark-grey to black, submetallic.
Fluorescence: none
Description: Analyses by SEM and XRD at the U.S. Geological Survey Lab, Denver, USA (Gene Foord), and the University of New Orleans Lab, New Orleans, USA (Jim Nazimoff & Al Falster). The acanthite crystals on wire crystals of native silver tend to grow and multiply after the specimens are collected... :~} - Wire crystals of "native silver" that are a dull lead-grey to grey-black and which crumble under the point of a pin are presumed to be acanthite pseudomorphs after silver.
Reference: A. Plante collection; R. Janules collection; A. Smith collection; et.al.
Anglesite
Formula: PbSO4
Habit: A wide range of crystals have been noted, from sharp blocky to short and long prismatic, all with a rhombic cross section. Rounded, equant, crystals have also been noted, exhibiting complex morphologies.
Colour: Colorless and glassy, sometimes turbid to milky-white.
Fluorescence: none
Description: Analyses by SEM-EDS at the University of New Orleans Lab, New Orleans, USA (Jim Nazimoff & Al Falster).
Reference: A. Plante collection; R. Janules collection; A. Smith collection; et.al.
Aragonite
Formula: CaCO3
Habit: "Flos Ferri" habit and grainy crusts. Some of the flos ferri crystals exhibit a bladed habit.
Colour: white (may be stained other hues)
Fluorescence: blue
Description: Most of the white crusts visible to the naked eye found on materials from this locality are the flos ferri variety of aragonite; specimens are only rarely of high enough quality to consider collecting them - most specimens are grainy crusts in which the crystals have been damaged severly.
Reference: A. Plante collection; R. Janules collection; A. Smith collection; et.al.
Arsenopyrite
Formula: FeAsS
Habit: Crude thin-tabular to thin-wedge-shaped, with lightly striated faces.
Colour: Very pale brassy - almost silver rather than brass yellow.
Fluorescence: none
Description: Uncommon at this locality, it may be told apart from pyrite and chalcopyrite here primarily by its much paler brassy color. The crystals my be lightly tarnished, but do not achieve the deep irridescent tarnish seen on the pyrite and chalcopyrite here. They were identified by the crystal habit and color.
Reference: A. Plante collection; R. Janules collection; A. Smith collection; et.al.
Aurichalcite
Formula: (Zn,Cu)5(CO3)2(OH)6
Habit: Crusts of acicular micro-crystals. The crystals may form a carpet of standing needles, or be formed of matted, jack-straw, crystals
Colour: Bluish-green to blue, more rarely green.
Fluorescence: none
Description: Analyses by SEM-EDS at the University of New Orleans Lab, New Orleans, USA (Jim Nazimoff & Al Falster).
Reference: A. Plante collection; R. Janules collection; A. Smith collection; et.al.
'Biotite'
Formula: K(Fe2+/Mg)2(Al/Fe3+/Mg)([Si/Al]Si2O10)(OH/F)2
Habit: Typical flakes in both the country rock surrounding the deposit and - more rarely - in the rocks of the deposit itself.
Colour: Black, dark brown in thin sheets.
Fluorescence: none
Description: Identified in the course of a USGS study (Cox, 1970) of the ore deposit.
Reference: Alan R. Plante, Gorham, NH.; USGS Bull 1312D
Brochantite
Formula: Cu4(SO4)(OH)6
Habit: Thin tabular to tabular crystals in druzes, fans, and crusts; also grainy to glassy crusts.
Colour: Medium dark green.
Fluorescence: none
Description: Analyses by SEM and XRD at the U.S. Geological Survey Lab, Denver, USA (Gene Foord), and the University of New Orleans Lab, New Orleans, USA (Jim Nazimoff & Al Falster).
Reference: A. Plante collection; R. Janules collection; A. Smith collection; et.al.
Calcite
Formula: CaCO3
Reference: Rocks & Min 80:249
Cerussite
Formula: PbCO3
Habit: Multiple habits - thin to medium thick tabular micro-crystals with chisel shaped terminations and edge faces - not rectangular or square; some approach being acicular. Twinning observed includes somewhat heart-shaped "fishtail" twins, more typical "fisht
Colour: Turbid transluscent - not glass-clear - to creamy white, sometimes the white crystals may have a tannish tinge.
Fluorescence: none
Description: Identified by visual obnservations and wet chemical analysis (acid test). May be confused with anglesite crystals here; but anglesites tend to be glass-clear - not turbid to creamy white - and are usually (but not always) more blocky.
Reference: A. Plante collection; R. Janules collection; A. Smith collection; et.al.
Chalcopyrite
Formula: CuFeS2
Habit: Massive, in small masses and veins inextricably mixed with pyrite; and as sphenoidal to thick tabular and nearly equant micro-crystals.
Colour: Brass-yellow, crystals usually deeply tarnished and may exhibit zoned brown and blue-black tarnish on different faces - may be zoned in concentric triangular patterns demarked by striations as well.
Fluorescence: none
Description: It is difficult to distinguish massive chalcopyrite from the pyrite at this mine, as the two tend to be inextricably mixed. Hardness tests seem to be ineffective, usually showing the hardness of pyrite. Visually, the chalcopyrite tends to be a deeper golden bronze than the lighter, brighter, pyrite - and it tends to exhibit deeper tarnish. The micro-crystals are more easily distinguished, being decidedly non-Isometric.
Reference: A. Plante collection; R. Janules collection; A. Smith collection; et.al.
Chamosite
Formula: (Fe2+,Mg,Al,Fe3+)6(Si,Al)4O10(OH,O)8
Habit: Micro-crystal spheres of tiny folia, which may be lightly scattered and easily distiguishable to densely packed forming crusts.
Colour: Medium to pale olive-green, trending into turbid grey.
Fluorescence: none
Description: Analyses by SEM-EDS at Excalibur Minerals (Tony Nickershir) and at the UNO lab (Jim Nazimoff & Al Falster). Most of the chamosite found here is as a rock-forming constituent of the country rock surrounding the fault vein deposit, where it is seen as typical flaky masses and veinlets; but it is also found as micro-crystals in vugs and on fracture seams in the ore rocks.
Reference: A. Plante collection; R. Janules collection; A. Smith collection; et.al.
'Chlorite Group'
Reference: USGS Bull 1312D
Copper ?
Formula: Cu
Habit: Wire micro-crystals
Colour: Copper
Fluorescence: none
Description: Only two or three possible samples found by Bob Wilken of New Milford, Conn., USA, and Alan Plante of Gorham, NH, USA. Neither collector is certain that these specimens are native copper - they may be something else with a tarnished copper look to them. There is insufficient material for wet analysis; a sample would need to be at least probed to determine what they are.
Reference: Bob Wilken collection; Alan Plante collection.
Cuprite
Formula: Cu2O
Habit: Octahedral micro-crystals, often as penetration twins.
Colour: Bright red.
Fluorescence: none
Description: Very tiny (less than 0.1 to about 0.1 mm) red octahedral micro-crystals, found scattered lightly on crumbly limonitic matrix, usually not too far away from weathered chalcopyrite.
Reference: A. Plante collection; R. Janules collection; et.al.
'Feldspar Group'
Habit: Massive material only.
Colour: Cream white and tan.
Fluorescence: none
Description: Species not determined, but both microcline and albite are probably present, perhaps oligoclase as well. Typical cream white to tan material with a dull to sub-vitreous luster. Samples of greenish material have been tentatively identified as a feldspar colored by impurities, perhaps zinc and/or copper.
Reference: "Lead-zinc-silver deposits related to the White Mountain plutonic series in New Hampshire and Maine," Dennis P. Cox, 1970, USGS Bulletin 1312-D
Galena
Formula: PbS
Habit: Massive, in pods to 14" across, veins to 10" wide, and stringers/veinlets to 1" wide. Also as matrix-frozen cubic crystals; and as cubic, modified cubo-octahedral, and octahedral micro-crystals.
Colour: Silvery-grey, may be either shinning metallic or dull metallic.
Fluorescence: none
Description: Galena was the principle ore mined at this site. The miners did a good job of recovering it for shipping to the smelter. Few specimens of any size - massive or as matrix-frozen crystals - remain to be found in the dumps. Crystals frozen in matrix are impossible to trim out into good mineral specimens. Therefore specimen-quality materials are largely restricted to secondary micro-crystals in vugs. A number of worthwhile finds have been made of these - showing some interesting modifications of the basic cubic shape.
Reference: A. Plante collection; R. Janules collection; A. Smith collection; et.al.; USGS Bull 1312D
Goethite
Formula: α-Fe3+O(OH)
Habit: Botryoidal crusts; spongy "limonitic" masses.
Colour: Botryoidal material black to dark brown; "limonite" dark to light brown.
Fluorescence: none
Description: Most (all?) of the "limonite" found here is hydrated goethite. Micro-botryoidal material is much less common, but still rather frequently found when looked for.
Reference: A. Plante collection; B. Januels collection, et.al.
Gold
Formula: Au
Habit: Possibly as wire micro-crystals in finely entwined strands.
Colour: Gold.
Fluorescence: none
Description: Reported as being found sparsely disseminated in massive pyrite and chalcopyrite (Cox, 1970). Also reported more recently (1999) as possible wire micro-crystals, but with the suspicion that the specimen may actually be native copper with an odd golden tarnish.
Reference: B. Wilken collection.
Gypsum
Formula: CaSO4 · 2H2O
Habit: Crusts and micro-crystals found growing on wood in the mine dump.
Colour: Milky white to clear.
Fluorescence: none
Description: Definitely a post-mine dump occurence.
Reference: B. Janules collection.
Hemimorphite
Formula: Zn4Si2O7(OH)2 · H2O
Habit: Micro-crystals in mats, jackstraw clusters, and radiating sprays of acicular to thin prismatic crystals; more rarely as single thin to stout micro-crystals with a nearly square cross-section.
Colour: Milky white to clear.
Fluorescence: none
Description: Easily mistaken for cerussite or aragonite here (samples are probably overlooked) but has a different habit and morphology that can be seen upon careful examination. The stouter prismatic crystals with a nearly square cross-section are decidely different from the other species' habits. An acid test using 20% HCl showed that both the aragonite and cerussite dissolved, while the hemimorphite did not.
Reference: A. Plante collection.
Hydrozincite ?
Formula: Zn5(CO3)2(OH)6
Reference: www.capitalmineralclub.org
'Limonite'
Formula: (Fe,O,OH,H2O)
Reference: Rolf Luetcke
Linarite
Formula: PbCu(SO4)(OH)2
Habit: Thin tabular, more rarely prismatic with chisel-shaped terminations.
Colour: Deep blue.
Fluorescence: none
Description: Analyses by SEM and XRD at the U.S. Geological Survey Lab, Denver, USA (Gene Foord), and the University of New Orleans Lab, New Orleans, USA (Jim Nazimoff & Al Falster). Most common of the blue minerals found at the site.
Reference: A. Plante collection; R. Janules collection; A. Smith collection; et.al.; Rocks & Minerals 81:208-213
Malachite
Formula: Cu2(CO3)(OH)2
Habit: As spherical clusters and crusts.
Colour: Green.
Fluorescence: none
Description: Identified by wet chemical analysis and visual observations. Most common of the green minerals found at the site.
Reference: A. Plante collection; R. Janules collection; A. Smith collection; et.al.
'Manganese Oxides'
Reference: Rolf Luetcke
Metazeunerite
Formula: Cu(UO2)2(AsO4)2 · 8H2O
Habit: Thin tabular plates, some crudely pseudo-hexagonal.
Colour: Yellowish-green, vitreous luster.
Description: Analysis by SEM-EDS at Excalibur Minerals (Tony Nickershir). Only a single specimen known as of Oct. '04 - found by Bob Wilkens, who had it probed at Excalibur. It is presumed that the U was derived from the granitic dike the fault occurs in. This is also the only arsenate species yet to be found at the site.
Reference: B. Wilkens collection.
Muscovite
Formula: KAl2(AlSi3O10)(OH)2
Habit: Typical small "books," and as sericitic masses.
Fluorescence: none.
Description: Found in both the granitic dike the fault is developed in and in the ore rocks. Some of the larger books have been shown to contain rutile needles as inclusions (Cox, 1970).
Reference: A. Plante collection; et.al.
Muscovite var: Sericite
Formula: KAl2(AlSi3O10)(OH)2
Reference: USGS Bull 1312D
Posnjakite
Formula: Cu4(SO4)(OH)6 · H2O
Habit: Crude thick-tabular crystals with rounded edges - rarely sharp - sparse on matrix, and as crusts.
Colour: Medium greenish-blue.
Fluorescence: none
Description: Identified by SEM and XRD at the Denver USGS lab (Gene Foord) and at the UNO lab (Jim Nizamoff & Al Flaster.) Crystals of posnjakite are fairly distinct at this site - not easily confused with other species.
Reference: A. Plante collection; B. Janules collection, et.al.
Pyrite
Formula: FeS2
Habit: As massive materials in pods, veins, stringers and veinlets; as matrix-frozen cubic crystals; and as micro-crystals having a variety of shapes: cubes, octahedrons, pyritohedrons - and one malformed crystal the shape of the Washington Monument!
Colour: Brass-yellow, metallic luster; may have slight surface tarnish.
Fluorescence: none
Description: The most common metallic brass-yellow mineral at this site. Usually massive material is inextricably mixed with chalcopyrite. Matrix-frozen crystals are impossible to trim into good specimens. Small to micro crystals are fairly common in vuggy ore rocks and may be found as attractive crystals.
Reference: A. Plante collection; B. Janules collection; A. Smith collection; et.al.; USGS Bull 1312D
Pyrrhotite
Formula: Fe7S8
Reference: Rocks & Min 80:249
Quartz
Formula: SiO2
Habit: Typical Trigonal prisms; in "cockscomb" parallel growth patterns (macro) and as small to micro-crystals in vugs.
Colour: Milky white (macros) to clear (micros), often stained reds and blacks by Fe and Mn.
Fluorescence: none
Description: Quartz is the most common mineral found at this site. It is found in both the ore deposit and in the surrounding country rocks. Most of it is massive; but in the ore deposit concentric plates of "cockscomb" crystals were formed, and the vuggy ore and gangue rocks contain vugs that are frequently lined with small to micro sized crystals. The latter situations are often hosts for "species of interest" here.
Reference: A. Plante collection; B. Janules collection; A. Smith collection; et.al.; USGS Bull 1312D
Ramsbeckite
Formula: (Cu,Zn)15(SO4)4(OH)22 · 6H2O
Habit: Thick tabular to "boxy" rhombic micro-crystals; may form crusts or be lightly scattered on matrix.
Colour: "Brochantite-green." (Easy to confuse with brochantite at this locality.)
Fluorescence: none
Description: Can be confused with brochantite crystals at this site but brochantite crystals are more thin-tabular to grainy - not rhombic and thick-tabular to boxy.
Reference: L. Rantos collection (Athens, Greece); A. Plante collection; B. Janules collection; Scott Whittemore collection; et.al.
Rosasite ?
Formula: (Cu,Zn)2(CO3)(OH)2
Habit: Micro-crusts, sometimes sub-botryoidal to botryoidal, more rarely as crudely tabular micro-crystals.
Colour: Bright, vivid, sky-blue with a waxy luster.
Fluorescence: none
Description: Mascot Mine "Unknown #7" - Once thought to be habits of the posnjakite found here, but SEM-EDS shows both Cu and Zn in significant quantities, suggesting the likelihood of it being rosasite - or possibly even claraite. It will take XRD analysis to determine the species.
Reference: A. Plante collection; B. Janules collection; et.al.
Rutile
Formula: TiO2
Habit: Acicular micro-needles including muscovite and biotite.
Colour: Silvery-black
Fluorescence: none
Description: Identified by Cox (1970). They are not present in all mica samples at the site. The needles in biotite can be difficult to see due to the dark color of the sheets - it takes very thin sheets with underlighting under a 'scope.
Reference: Rocks & Minerals (2005) 80:242-261 New Hampshire Mineral Locality Index; USGS Bull 1312D
Schulenbergite
Formula: (Cu,Zn)7(SO4)2(OH)10 · 3H2O
Habit: Crusts, foliated sheets, crude hemispheres, and crude rosettes of extremely tiny acicular needles
Colour: Very pale sky-blue to slightly greenish-blue, with a pearly to somewhat waxy luster.
Fluorescence: none
Description: Indentified by SEM and XRD at the Denever USGS lab (Gene Foord), the UNO lab (Jim Nazimoff & Al Falster), and Excaliber Minerals (Tony Nickershir). Schulenbergite can be confused with aurichalcite here; but the acicular natue of aurichalcite crusts and mats of needles is obvious - while the schulenbergite specimens appear either platy or grainy at magnifications of under approx. 120X (or greater?) The acicular nature of the schulenbergite was only revealed by SEM imaging.
Reference: A. Plante collection; B. Janules collection; A. Smith collection; et.al.
Serpierite
Formula: Ca(Cu,Zn)4(SO4)2(OH)6 · 3H2O
Habit: Lath-like micro-crystals with jagged terminations, in clusters exhibiting both parallel growth and jackstraws.
Colour: Bright medium blue.
Fluorescence: none
Description: Identified by SEM-EDS at the UNO lab (Jim Nazimoff & Al Falster) and visual observations. Serpierite is rare at this site, but a number of samples have been found. The lath-like shape and jagged terminations distinguish them from other blue species here, particularly from linarite (which also is darker blue in color.)
Reference: A. Plante collection; B. Janules collection.
Siderite
Formula: FeCO3
Habit: Typical clusters and vug linings of rhombic crystals, from micros to individuals to about 1.5 to 2 cm.
Colour: Dark brown to light tan, sometimes almost honey colored, often stained blue-black by Mn-O and having an sub-iridescent appearence.
Fluorescence: none.
Description: Identified by SEM-EDS at the UNO lab (Jim Nazimoff & Al Flaster), and by repeated visual and wet analysis. The SEM analyses showed that even the lightest colored specimens are Mn-rich: siderite var. manganoan. This species is probably the single "collectable" mineral found at the site as non-micro crystals (along with an occasional quartz crystal specimen...)
Reference: A. Plante collection; B. Janules collection; and many others...; USGS Bull 1312D
Silver
Formula: Ag
Habit: As micro-grains in galena; and as wire micro-crystals, straight, curved, coiled, and in arborescent (bush-like) clusters.
Colour: Dull silvery-grey to dark grey, often coated with a dark-brown to black crust encasing the wires.
Fluorescence: none
Description: Identified by SEM-EDS at UNO lab (Jim Nazimoff & Al Falster), and by wet analysis and visual examination. Wire crystals of native silver are difficult to find in among the typically dark brown to bluish-black Mn-O coated rocks in the mine dumps, it takes a concerted effort looking specifically for them - but quite a few finds have been made this way. Specimens in which the silver is encased in a dark-brown to black crust are the most difficult to spot. Specimens of wire crystals curled into coils or having the arborescent habit tend to be the most interesting. Sometimes clusters of the silver are accompanied by spheres of malachite, with the malachite perched on and/or pierced by the wires of silver. Sometimes the wires have thorn-like acanthite crystals on them - which have been noted to multiply and increase in size *after* being brought home. Wires that are dull pencil-lead grey in color and which are crumbly under the point of a pin are presumed to be native silver that has pseudomorphed into acanthite. Most often found in vugs of siderite crystals, but also fund in vugs of quartz crystals and in other associations.
Reference: A. Plante collection; B. Janules collection; S, Andrews collection; et.al.
Smithsonite
Formula: ZnCO3
Habit: As micro-crystals and sub-botryoidal to somewhat stalactic crusts; and as crudely rhombic crystals with a rice grain appearance.
Colour: "Frosted" greyish-white to bluish-grey crusts, looking much like "dirty melted candle wax."
Fluorescence: none
Description: Identified by SEM-EDS at the UNO lab (Jim Nazimoff & Al Falster). Analyses show a note worthy amount of Cd to be present. Most typically found as micro-crusts and sub-botryoidal clusters; more rarely as "rice grain" crystals; and occasionally as stacked sub-parallel rhombs resembling pine-cones. It is believed that some of the micro-crusts and sub-botryoidal to botryoidal clusters of "unknowns" that are obviously not malachite or other knowns are smithsonite stained greens and blues by zinc and copper.
Reference: A. Plante collection; B. Janules collection; A. Smith collection; et.al.
Sphalerite
Formula: ZnS
Habit: Found largely as massive material; but also found as micro-crystals in vuggy gangue rock with a blocky, crudely pyramidal, shape that may appear pseudo-hex. with a hexagonal basal termination containing triangular striations.
Colour: Mostly black to reddish-black, but occasionally very dark reddish-brown; with a sub-iridescent luster, more rarely glassy in the smallest, reddest, crystals.
Fluorescence: A dull deep red under short-wave UV.
Description: Identified by SEM-EDS at the UNO lab (Jim Nazimoff & Al Falster), and by visual identification. As common as the massive material is in the mine dumps, it is probably often overlooked - taken as "more Mn-O tarnished siderite." But it's nearly metallic luster and coarse cleavage at varying angles in freshly broken material distinguish it from the siderite. Sometimes the massive material has a greenish olive-yellow color that also distinguishes it from siderite here. The micro-crystals are rather difficult to find - camouflaged in among all the other Mn-O stained materials, and usually occuring in vugs lined with siderite.
Reference: A. Plante collection; B. Janules collection; A. Smith collection; et.al.
Wroewolfeite ?
Formula: Cu4(SO4)(OH)6 · 2H2O
Habit: Crude arrowhead shaped (or "spearmint leaf" shaped) micro-crystals in clusters and flat radial sprays on matrix.
Colour: Pale green.
Fluorescence: none
Description: SEM-EDS analysis at Excalibur Minerals (Tony Nickershir) suggests wroewolfeite as the identity of this unknown from the site; but visual observations - color and shape - put this in doubt. XRD analysis is needed... Known from only a single specimen as of Oct. '04.
