Cox (p. 65) describes the graphite from Pakawau as more or less 
schistose, and varying a good deal as regards purity. A. Liversidge, in 
Trans., vol. 10, 1878, p. 490, describes a sample of Nelson (Pakawau) 
graphite in the Otago Museum as compact, with lamellar and petaloidal 
structure, and requiring purification to render it of commercial value. 
In 1889 Park visited the old graphite-mine near Pakawau, and described 
it as follows (Rep. Geol. Explor., No. 20, 1890, p. 205) : “ Plumbago-mine.— 
The old workings at this place are situated on the rising ground at the 
south-west corner of the Pakuwau Inlet. The graphite is largely mixed 
with quartz and earthy impurities. It occurs as a bed about 7 in. thick, 
contained in blown arenaceous mica-schists, which are overlain by hard 
siliceous sandstones and cherts, forming the higher portion of Mount Misery.” 
A section given by Park shows that the graphite layer outcrops where some 
terraced flats end and hilly country begins. It is represented as dipping 
at an angle of nearly 80° to the westward. 
The following analyses are believed to represent graphite from the 
district, though the last three (Nos. 5, 6, 7) are ascribed to Nelson, and 
there is no clue by which to trace their further origin

(1) (2). Lab. No. 18, 1883, p. 51. No. 1 is from the “New Lease,” 
as taken from the ground, undressed. No. 2 is crude chips, moulded, 
washed, and pulverized. These samples were contributed by Mr. John 
Bathgate, and are recorded as from Nelson. The “ New Lease ” was 
probably near Pakawau (see below).

A map or “ General Plan of the Collingwood District,” published in 
Rep. Geol. Explor. No. 8, 1877, opposite page lv, shows the Pakawau 
Plumbago-mine as situated somewhat over a mile south-west of Pakawau 
Inlet. Fully two miles south-west of this again is an area on the north 
east side of Mount Burnett marked “ Plumbago Lease.” This is possibiy 
the locality designated “ New Lease ” in Lab. No. 18, p. 51 (see abore), 
but there is no solid evidence for this supposition.
