"The Edi-Cheshunt turquoise field occur in northeastern Victoria about 45 km northeast of Mansfield. Eight outcrops occur in a series of belts lying to the east of the small settlement of Cheshunt. The belts commence about 7 km southeast of Cheshunt and extend in a northwesterly direction over a distance of about 5 km in the Black Range. These eight turquoise deposits were being worked in the 1890's.
Locality No.1 was the most southerly location and probably the largest working, 60 m wide and 15m deep.
Locality No.2 was 0.9 km northwest of Locality No.1. Known as the New Discovery Mine, it was the first deposit opened.
Locality No.3, 3.6 km from Locality No.1 was known as Mount Avis Extended Mine.
Locality No.4, about 0.9 km from Locality No.3, was known as the Mount Avis Mine.
Locality No.5, nearly 5 km from Locality No.1 onsists of a cutting and a tunnel driven for 18 m
Locality No.6 was on a farm near Sheep Station Creek, but little work had been done mainly due to the working being only a short distance above creek level.
Location No.7, about 300 m northwest of Locality No.6 and known as Masson Company's workings, consisted of a deep narrow cutting in the hillside and a shaft.
Locality No.8 consisted of only a small opening 3.2 km northwest of Locality No.7.
The tunnels at Locality 4 and 5 are still accessible whilst the large workings at Localities 1 and 3 are quite impressive.
Little is known of how much turquoise was mined from the area and to whom it was sold.
No records can be found after 1921 of any further mining in the district."

Detailed Mineral List:
| ⓘ Crandallite Formula: CaAl3(PO4)(PO3OH)(OH)6 Description: "Crandallite-Millisite were interpreted by IMC (1967) to occur with quartz and collophane in the phosphatic lenticles. |
| ⓘ Dufrénite ? Formula: Ca0.5Fe2+Fe3+5(PO4)4(OH)6 · 2H2O Description: "The iron phosphate mineral originally reffered to as dufrenite by Howitt (1913) has been identified as rockbridgeite by X-ray diffractionand microprobe analysis. Seams of dufrenite occurring with turquoise were said by IMC (1967) to be widespread, however no evidence for this exists on Museum specimens." |
| ⓘ Magnesite Formula: MgCO3 |
| ⓘ Planerite Formula: Al6(PO4)2(PO3OH)2(OH)8 · 4H2O Description: "On some specimens from the new road cutting near Cheshunt, soft, pale blue crusts of platy crystals overgrowing turquoise have a turquoise like X-ray diffraction pattern but are very low in copper. They are probably planerite." |
| ⓘ Pyrite Formula: FeS2 Description: "Cubes of pyrite up to 1 mm across may be found in inweathered black slates." |
| ⓘ Quartz Formula: SiO2 Description: "Quartz sometimes occurs with the turquoise as colourless, transparent crystals only a few mm long." |
| ⓘ Rockbridgeite Formula: Fe2+Fe3+4(PO4)3(OH)5 Description: "The rockbridgeite from the northern most lode of the Cheshunt deposit is a massive, earthy, greyish green material. Occasional small cavities a few millimetres across may be lined with deep olive-green to almost black prismatic crystals." |
| ⓘ Sasaite Formula: (Al,Fe3+)14(PO4)11(SO4)(OH)7 · 83H2O Description: "This rare mineral occurs as snow-white glistening masses filling veinlets less than 1 mm thick in black slate. Magnified, using the scanning electron microscope, the veinlets are composed of layers of platy crystals. Small quartz and pyrite crystals occur with the sasaite, and veins of pale blue variscite may cut it." |
| ⓘ Turquoise Formula: CuAl6(PO4)4(OH)8 · 4H2O Localities: Edi-Cheshunt turquoise field, Whitfield, Rural City of Wangaratta, Victoria, Australia Mt Avis Extended, Edi-Cheshunt turquoise field, Whitfield, Rural City of Wangaratta, Victoria, Australia Mount Avis Mine, Edi-Cheshunt turquoise field, Whitfield, Rural City of Wangaratta, Victoria, Australia Masson Company workings, Edi-Cheshunt turquoise field, Whitfield, Rural City of Wangaratta, Victoria, Australia Description: "In the Edi-Cheshunt field the turquoise occurs as compact veins and fracture fillings up to 2 cm thick but generally less than 0.5 cm. The veins may follow either planar fractures or the surface of small irregular folds. The colour of the turquoise varies from greenish and pale blue, particularly near the surface, to interse sky blue shades. The appearance varies from subvitreous and translucent in the deeper blue material to chalky and opaque in pale varieties. Cavities with globular linings occurs in some veins." |
| ⓘ Variscite Formula: AlPO4 · 2H2O Description: "A few veinlets, less than 1 mm thick, of earty pale blue variscite have been found in specimens of black slate. It occurs with sasaite and turquoise." |
| ⓘ Wavellite Formula: Al3(PO4)2(OH,F)3 · 5H2O Description: "Wavellite is rare as thin colourless rosettes of fibrous crystals on joint planes in black slate. It also occurs as compact, white, fibrous linings to veins filled with turquoise." |
