KAMARANGAN PROJECT
Kamarangan Porphyry Copper Target
The Kamarangan prospect is centrally located in a
large aeromagnetic anomaly approximately ten kilometres in diameter.
The area is underlain by a well-banded calcareous
sequence that appears to be at least 1,600 metres wide. The
calcareous sequence has been intruded by a complex of fine- to
coarser-grained diorites and some andesite bodies. The intrusives
have changed the calcareous rocks to skarn rocks over an approximate
area of 1,600 metres by 1,400 metres (Figure 2). The skarn area is
open to the east under the younger overlying limestone. The surface
geology outcrops are limited mainly to magnetite-rich horizons with
secondary hematite.
Some of the skarn rocks may contain variable amounts of garnet,
diopside, epidote and pyrite. Areas of siliceous hornfels and
unaltered massive limestone were also intersected in the drilling.
Discussion
Table
1 contains a summary of the significant drill hole results.
The intersection of a "fertile" diorite
and other vectors from the drilling indicate a possible porphyry
copper source to the east-northeast of the drilling conducted to
date based on:
-
Copper and gold values in dioritic rocks tend
to be higher in holes KAM 1 and 2, and while visible copper
minerals are present in KAM 4 although at a lower level than
in KAM 1 and 2;
-
Molybdenum mineralisation is visible in KAM 1
to a maximum value of 244 ppm and averages 37 ppm over the
last 74 metres of the hole from 357.70 metres depth;
-
Molybdenum mineralisation is visible in KAM 2
to a maximum value of 138ppm and averages 41 ppm over the last
46 metres of the hole from 405 metres depth. Other less
coherent zones are present higher up in the hole.
-
Skarn hosted gold with minor copper
mineralisation is strongest in KAM 7 in the northeast of the
drilled area, suggesting this hole is close to a
mineralisation source.
The well mineralised magnetite skarn in KAM 1 (26 to
42.3 metres) and in KAM 2 (40 to 44.2 metres) and the wide skarn
style mineralisation in KAM 7 (0 to 19.5 metres, 211.1 to 267.1
metres and 410.8 to 426.8 metres) could also be interpreted to be a
halo above and around the 250 by 130 metres elongate deep magnetic
anomaly shown on Figure 6. This anomaly could possibly be
interpreted as a pencil porphyry style target.
Drill hole magnetite-rich samples will be submitted
for estimation of the magnetite contents and preliminary
metallurgical testing if further assessments regarding the
prospect's magnetite potential are positive.
Induced polarisation and ground magnetics surveys
are underway.
