Classic Minerals (ASX: CLZ) is a Perthbased mineral exploration Company focused on advancing its Fraser range project E28/1904, in Western Australia. The Fraser range Project is approximately 40km northeast of Sirius resources’ NL (ASX: SIr) Nova and Bollinger nickel-copper discoveries, and has historic nickel-copper-zinc soil anomalies.
Highlights:
-
Petrology undertaken on RC chips and diamond core from Mammoth Ni-Cu deposit confirms similar rocks and sulphide mineralisation to Nova Ni-Cu deposit
-
The rocks are garnet bearing basic granulites
-
Sulphide minerals are dominantly pyrrhotite with subordinate amounts of pentlandite and chalcopyrite.

Classic Minerals Ltd (ASX: CLZ) said today that the results of petrology analysis undertaken on core and rock chips from its Mammoth nickel-copper discovery have confirmed that Mammoth has similar rock types and sulphide mineralisation to the nearby Nova Ni-Cu deposit.

According to consulting mineralogist, roger Townend, the mineralised horizons (chalcopyrite pentlandite pyrrhotite garnet pyroxene plagioclase) seem similar to the mineralised pyroxene garnet gneiss from the Nova deposit.
“The garnet bearing granulite with its pyrrhotite pentlandite chalcopyrite mineralisation appears similar to the principal mineralised host rock (PSG pyroxene garnet gneiss) described at the Nova deposit at the Fraser range,” he said.

The presence of garnet is a phenomenon that distinguishes them from the nickel ore types of Voisey Bay. The garnets at Mammoth are red almandine garnet. In addition to the garnet, the mineralised core was also found to contain ilmenite and pentlandite that is particularly cobaltiferous.
results from the latest rC programme at Mammoth have also been received showing the continuity of mineralisation along strike and at depth.
All six holes have continued to intersect sulphides (Table 1, Figure 3) confirming that Mammoth is intersecting Nickel Copper Cobalt mineralisation from the south west line and on every line for 240m, with mineralisation plunging to the north east. The mineralisation remains open to the north east and southwest.
The rC drill rig has now rolled on to drilling some initial test holes into eight other high priority targets along the 6km conductive target ‘hot’ zone that has been identified extending south west from Mammoth.
“These findings at Mammoth are very important as they highlight that we are in the right rock types for continued nickel exploration success,” said Classic Minerals Managing Director Justin Doutch.
“We have a strong programme in place that will see us continue to build a picture of the extent of the mineralised opportunity around the northern end of our Fraser range tenement where we believe there are some exceptional target opportunities for continued discovery.”
Six quarter core samples from the sulphide mineralisation zone of FrDh001 were taken for petrographic and mineragraphic identification finding the host granulites contained plagioclase and pyroxenes as well as garnets. Granulites are high metamorphic grade rocks formed at high pressure and temperature.
Analysis of the samples found the mineralisation varies from disseminated sulphides to blebby to massive sulphides (Figure 1)

The pentlandite (nickel iron sulphide) occurs at the edges of the pyrrhotite grains or as exsolved crystals within the pyrrhotite grains, as shown in Figure 2.

The pentlandite was determined by Scanning Electron Microscope (SEM) to have the composition Ni 35%, Fe 26%, Co 2.5% and S 36.5%. The Chalcopyrite (copper iron sulphide) occurs as inclusions ranging from 100 to 500microns within the coarser pyrrhotite meaning they should easily be concentrated during processing. It also extends as narrow veins through plagioclase. There is a notable association of sulphides with the biotite which often appears to cross cut the sulphides.
The partly cored hole FrDh001 was drilled as a twin hole for rC hole FrrC039, both drilled at -60 degrees to 311 degrees true azimuth. The twin hole was cored from 38.7m to 52.05m. Immediately below the basic granulite at 44.7m depth downhole is a silicified felsic granulite, with numerous quartz veins.

Background to exploration on the Fraser Range
Exploration for nickel in the Albany Fraser range was undertaken in the late 60s by several companies forming a joint-venture. Consultants from Newmont Canada had suggested an analogy between the Thompson nickel belt in Manitoba and the Proterozoic rocks from this region.
The results of this exploration program found low grade nickel and copper sulphide mineralisation (pentlandite pyrrhotite chalcopyrite) at Gnama South in rocks that range from peridotite to anorthositic norites. (Tyrwhitt and Orridge, p.405, Economic geology of Australia, and Papua New Guinea volume 1, 1975). It was noted, that these ultramafic rocks were associated with highgrade pyroxene granulites that also included garnet bearing biotite gneiss and garnet amphibolite gneiss. The nickel mineralisation was classified under the gabbroid associated deposits rather than the Archean komatiite ores. It was not apparently present in garnet bearing rocks.
The Thompson nickel ores in Canada are present in ultramafic rocks classified as komatiites but of Proterozoic age. The nickel copper sulphide bearing bodies are hosted by a series of meta sediments and volcanics, that range from amphibolite to granulite grade. The nickel deposits appear to be associated with a particular stratigraphic unit described as a biotite rich paragneiss (Ospwagan Group) that are rich in barren sulphides. The juxtaposition of the nickel bearing ultramafics and the sulphide rich metasediments is regarded as important in locating new ore occurrences. This has been used as a model for Fraser range deposits, but these lack

ultramafics to date.
Several nickel ore occurrences have recently been reported by Sirius resources from the Albany Fraser range area. An earlier drilling program found (near The Eye) non economic mineralisation (pyrrhotite pentlandite chalcopyrite) in mafic granulites. Subsequent further drilling in the location detected significant mineralisation of a nickel, copper sulphide ore, being pyrrhotite pentlandite chalcopyrite showing exsolution texture in a hypersthene augite garnet hornblende labradorite quartz gneiss. This was concluded to be a new type of nickel ore for Western Australia i.e. pyroxene garnet gneiss (PXG). A second discovery allied to the Nova deposit (Bollinger) shows some differences but is essentially of a similar type.
As reported by Eagle research (June 2013), Sirius considers that the Nova deposit resembles the nickel belt mineralisation of Thompson and also possibly Voiseys Bay. The Santa rita nickel ore occurrence from Bahia Brazil is also quoted as a possible analogous deposit. The Norilsk nickel deposits are also a possible model.
The sulphide mineralisation in all these deposits are consistently pyrrhotite pentlandite and chalcopyrite whether in basic or ultrabasic host rocks. There can be some minor differences in the ores.
