TERTIARY BEGINS DRILL TESTING OF NORWEGIAN
PLATINUM PROSPECT

Programme On Scandinavian Platinum/Copper-Nickel Projects
Tertiary Minerals
plc has commenced a drilling programme to follow up a new discovery
of platinum group elements (PGE) made during recent summer field
programmes at its Finnmark project in Norway. This is one of a number
of proposed drilling programmes to test for PGE and nickel-copper
mineralisation on Tertiary’s Scandinavian projects over the
next few months.
PGE mineralisation has previously been identified on Tertiary’s
various claims in the Finnmark district including wide intervals
of mineralisation intersected in drilling by the Norwegian Geological
Survey at both Porsvann and Karenhaugen. The company notes, however,
that this mineralisation is hosted by small intrusions and has limited
tonnage potential. The current drilling target, by contrast, is
hosted in a 10km long ultramafic intrusion which features a coincident
geophysical anomaly extending along strike for several hundred metres.
This latest target was initially discovered in a small outcrop containing
low-grade disseminated nickel and copper sulphide minerals in ultramafic
rock which, in two grab samples, averaged 2.5g/t platinum-palladium-gold.
Subsequent geophysical exploration identified a zone of anomalous
conductivity associated with the PGE-bearing outcrop and extending
along strike for some considerable distance.
Shallow drilling within this zone during the 1970s recorded low-grade
nickel-copper sulphide mineralisation but the drill core was never
assayed for PGEs. Tertiary therefore considers that the target conductive
zone could indicate a more extensive zone of nickel-copper sulphide
mineralisation which may carry PGE values.
The current drilling programme will comprise four holes, two of
which will test the geophysical anomaly beneath the outcropping
PGE mineralisation. The other two will test it 200m north of the
outcrop and 700m to the south. The latter location is along strike
and to the south of the holes drilled in the 1970s. Results are
expected towards the end of May.
