Native Copper, Cu, occurs :—I1st. In plates associated with the copper 
deposits of the serpentine belt in Nelson. Specimens have been obtained at 
Aniseed Valley ; Dun Mountain; and D’Urville Island. It has also been 
found at Moke Creek, Lake Wakatipu; at the Great Barrier Island; and at 
the Perseverance Mine, Collingwood. The presence of copper in the Dun 
Mountain has been known since 1853:—2nd. As grains disseminated 
through a granular serpentine at Aniseed Valley, Nelson, where the native 
copper forms an average of 5 per cent. of the rock mass, but the extension 
of the deposit has not been proved:—8rd. As fine grains in basaltic dykes 
which cut through trachydolerite breccias near the Manukau North Head, at 
which place it is of no economic value on account of the small percentage 
present, but is of great interest from its unusual mode of occurrence. 
Cuprite, C4,.—This mineral, which, when pure, contains 88°9 per cent. 
of copper, is only known to oceur in the serpentine belt of Nelson, where 
it is found in various degrees of purity, containing from 10 to 88-9 per 
cent. of copper. As pointed out by Dr. Hochstetter (New Zealand, p. 475), 
_the richer deposits of ore form lenticular-shaped masses, which, when 
followed, may increase to a certain distance, but then disappear again in & 
thin wedge. The most notable discovery of this mineral which has yet 
been made is that known as the Champion Lode, in Aniseed Valley, which 
was found by Mr. Stratford, a few months ago. This deposit is reported to 
be 5 feet in width, and is exposed on the surface for some distance. It has 
not, however, yet been worked. Specimens of this ore, which consist of 
Cuprite and native copper, have yielded as high a return as 90 per cent. 
metallic copper. Some rich patches of the ore have also been found at the 
Aniseed Valley Mine, Dun Mountain, and D'Urville Island, in each case 
associated with copper glance, but no deposits of any great importance have 
yet been met with and the ore is in all cases more or less ferruginous. No

where that mineral oceurs in various parts of the Nelson serpentine belt. 
It is always in a massive form, and has not yet been shown to occur in 
deposits of sufficient extent to prove remunerative ‘The same remarks with
