"The mine is located about 1.8 km south east of Woods Point. Discovered in the late 1980's or early 1900 the mine had a short life and was abandoned by 1905. 1810 oz. of gold were recovered from 2368 tons of ore from this mine.
The mullock heap now is partly overgrown and the main adit is well hidden at the upper end of the mullock heap. This adit has been driven about 100m to a T-intersection, with both branches leading to air shafts. Halfway up the gully there are two shafts and one adit, the other having caved in near the entrance. It is possible that the shafts connect with the lower workings."

Standard Detailed Gallery Strunz Chemical ElementsDetailed Mineral List:
| ⓘ Albite Formula: Na(AlSi3O8) Description: "Albite is not common in the quartz veins. When it is present, it forms uniformly small polysynthetic twins about 3-4mm in maximum dimension. Crystals are often flawed or milky." |
| ⓘ Ankerite Formula: Ca(Fe2+,Mg)(CO3)2 Description: "Ankerite is of major importance within the quartz veins and may easily be mistaken for dolomite. A continuous series between those two minerals is very likely in the quartz veins. Slightly deformed, reddish-brown rhombohedra, deposited later than dolomite, are probably ankerite." |
| ⓘ Arsenopyrite Formula: FeAsS Description: "Arsenopyrite, with pyrite, is one of the major ore minerals within the dyke belt. It occurs in pyramidal crystals sometimes exhibiting a slight helicoid torsion. Crystals may reach 1.5 cm across. The crystal habits include elongated crystals forming divergent groups, or star-like aggregates. Cruciform twins have also been recorded." |
| ⓘ Brookite Formula: TiO2 Description: "Brookite if found only in a quartz vug at the Little Comet mine. About 10 specimens have been recognized, most of them unfortunately being broken. They are associated with either quartz or albite. The colour may vary from sky blue to honey-yellow, sometimes with a slight reddish tinge. The crystals are striated. Brookite forms delicate, thin plates between 0.5 and 0.3 mm thick and up to 1 cm in length. The crystals show a consistent habit although a few are unusually thick. Some of the darker crystals are a mixture of brookite and rutile." |
| ⓘ Calcite Formula: CaCO3 Description: "Calcite is a major vein constituent, although less common than quartz and dolomite. It occurs in the same crystal habit as dolomite and is often mistaken for the latter mineral. The typical habit is that of thin flattened rhombohedra showing growth marks. |
| ⓘ 'Chlorite Group' Description: "Chlorite is a late-stage mineral, sometimes occurring as inclusions in quartz, but more often as encrustations on the vein minerals." |
| ⓘ Dolomite Formula: CaMg(CO3)2 Description: "Dolomite is considered to be the major carbonate phase at the Little Comet mine and forms thin flattened rhombohedra showing 'growth marks'. Colour is usually off-white or cream, but may be greenish due to dispersed chlorite inclusions or coatings." |
| ⓘ Galena Formula: PbS Description: "Galena has been recorded in minor amounts in quartz veins in the altered dyke at the Little Comet Mine." |
| ⓘ Gypsum Formula: CaSO4 · 2H2O Description: "Gypsum is always a secondary mineral, forming crusts on coarsely crystalline quartz at the Little Comet Mine." |
| ⓘ Malachite Formula: Cu2(CO3)(OH)2 Description: "Malachite is found as an alteration production of chalcopyrite and is rarely crystallized. It was found at the Little Comet Mine associated with quartz and dolomite." |
| ⓘ Native Gold Formula: Au Description: "The gold from this mine is much sought after for specimens and sometimes takes a crystalline form. It is also found embedded in cubes of pyrite. One mass of gold aggregating in weight more than 80 oz. (2,490 gm.) was discovered in 1913 at a depth of 67 m. It was associated with a little quartz and some limonite and malachite." |
| ⓘ Pyrite Formula: FeS2 Description: "Pyrite is a major mineral in the quartz veins. There is a wide variety of crystal habit including cube, pyritohedron, octahedron and less commonly, complex combinations of cube and pyritohedron and modified by the faces of the octahedron. Intricate twins and group of crystals also occur. Crystal size ranges from 0.1 mm up to 3 cm." |
| ⓘ Quartz Formula: SiO2 Description: "Quartz is the major vein mineral and clusters of crystals up to 5 cm. long in vugs are not unusual. A characteristic feature of these crystals is that one rhombohedron is generally more developed than the other." |
| ⓘ Rectorite Formula: (Na,Ca)Al4((Si,Al)8O20)(OH)4 · 2H2O Description: "Rectorite is a soapy-looking, white, late vein filling mineral, very common in vugs at the Little Comet mine." |
| ⓘ Rutile Formula: TiO2 Description: "Rutile occurred as a few bronze coloured needles growing on brookite crystals. These needles are minute and can only be detected by careful examination. Rutile is also enclosed within the brookite crystals." |
| ⓘ Sphalerite Formula: ZnS Description: "Sphalerite is another minor constituent in quartz veins at the Little Comet Mine. The crystals may vary from honey-yellow to black with a reddish tinge. Crystals may be up to 3 mm across." |
| ⓘ 'Tetrahedrite Subgroup' Formula: Cu6(Cu4C2+2)Sb4S12S Description: "Tetrahedrite is a minor constituent of quartz veins. It occurs as crystalline aggregates, more rarely as small tetrahedral. The period of deposition seems to coincide with that of gold." |
