2. REVIEW OF OPERATIONS
2.1 Indonesia
Pungkut Gold Project, Sumatra (75%)
Exploration activities conducted by Oropa during the
Quarter on its 75%-owned Pungkut Project, located
in North Sumatra, Indonesia, included:
Sambung Prospect:
13 diamond drill holes completed for 774m
Inferred Mineral Resource of 1.14 million
tonnes at 2.6g/t Au, for 100,000 ounces of
gold estimated
Additional high-priority drill target
identified near the Sambung Inferred
Resource which could represent the source
of the Sambung mineralisation.
Sihayo 1 North:
Re-logging of all diamond drill holes.
Tambang Ubi:
6 diamond drill holes completed for 622m.
Potential gold/copper porphyry targets
identified from the interpretation of recent
ground magnetic surveys.
High-grade copper and gold values returned
from rock chip sampling from local miners’
adits up to 3km west of Tambang Ubi.
These programs were interrupted in mid-December,
following a large earthquake near Tambang Ubi, which
resulted in a number of fatalities at a local village, and by
torrential rains that inundated Sumatra and other parts of
Indonesia during December and early January.
Sambung Prospect
The Sambung Prospect is located in the North Block of
the Pungkut Project, approximately 2km south of the
610,000 oz Sihayo 1 North Inferred Gold Resource. It
represents the second of numerous potential resource
centres at Pungkut to be tested by Oropa.
Field exploration activity during the Quarter focused on
completing the drilling required for the Sambung resource
calculation to be carried out. Drilling for the Quarter
totalled 774m, increasing the total diamond drilling at
Sambung to 5,421m.
Best intersections from the recent drilling include:
SAMDDD071: 7m @ 6.27 g/t Au from 29m
SAMDDD072: 7m @ 2.16 g/t Au from 9m
SAMDDD073: 4m @ 3.60 g/t Au from 6m
Gold mineralisation at Sambung occurs in shallow, gently
dipping blankets of siliceous jasperoids, within Permian
limestone and volcanogenic sediments, where
hydrothermal fluids have ponded below Tertiary
sediments.
Higher grades occur within hydrothermal breccias in the
jasperoids. The Sambung resource may be contained
within a large slump block and during the March Quarter,
strong IP resistivity anomalies up-slope will be drilltested
for possible in-situ feeder mineralisation.
The exploration strategy will be to continue to identify,
define and drill new targets at Sihayo-Sambung with the
objective of outlining sufficient resources to justify drillout.
A new drill target has already been identified within
the Sambung area, and a geological review will be
undertaken to generate additional targets in the Sihayo-
Sambung area.

Sambung Inferred Mineral Resource
This Inferred Mineral Resource estimate, the first for the Sambung prospect was estimated using Ordinary
Kriging interpolation inside grade-based (0.5g/t) wireframes, which follow known geological trends.
The Sambung mineralisation, as defined by these 0.5g/t wireframe, occurs in three sub-horizontal lenses
within 50m of the surface. The Inferred Resource quoted is a subset based on a block model cut-off of
1.5g/t and represents three distinct higher grade zones of reasonable coherency/continuity. The resource is
classified as ‘Inferred’ due to the broad drill spacing introducing geological uncertainty, and resolvable
issues of data QAQC and surface DTM.
The addition of the Sambung Inferred Resource to the Sihayo 1 North Inferred Resource brings the total
inferred resource to 710,000 ounces of gold. Further drilling is required to advance the resource
confidence in these areas.

Tambang Ubi
Drilling commenced in the historic Dutch Tambang Ubi
skarn Au-Cu mine area in the southern block to test for
repetitions of the deposit and to assess the extent of
extraction of the main lode by the Dutch miners, as well
as for down-dip continuity of the deposit.
Best intersections from this drilling include:
TUDDD001: 0.9m @ 6.27g/t Au & 0.47% Cu from
35.7m.
0.5m @ 12.63g/t Au & 0.76% Cu from
43.5m.
TUDDD002: 4m @ 3.42g/t Au & 0.48% Cu from
22m.
TUDDD002: 1m @ 4.55g/t Au & 0.22% Cu from
22m.
Further drill results are yet to be received for the
Tambang Ubi program, including results for hole
TUDD005, which tested for the down-dip extension and
intersected zones of skarn alteration with visible bornite
and chalcopyrite within the down hole interval 121 –
131m.
Drilling was suspended from 18 December to 4 January
due to a major earthquake in the district. Several more
holes are planned to complete initial testing at Tambang
Ubi.
Results from ground magnetic surveying during the
previous quarter outline a significant magnetic high
adjacent to the Tambang Ubi deposit. Analysis indicates
that the top of the magnetic high is approximately 100m
below surface in the general direction of the plunge of the
ore-body. Drilling is currently underway to test this target
for possible porphyry Au-Cu mineralisation.
Perth-based Southern Geoscience has been contracted to
undertake a structural interpretation incorporating the
magnetic survey data to assist with identifying additional
target areas.
Gridding is currently in process to enable extension of
ground magnetic survey coverage.

Figure 2: Tambang Ubi Drill Hole Location Plan and Regional Au in Rock Chip Samples
Pionggu – Sunda Parit – Sunda Parit Jae
Recent rock chip results from this prospect (Table 4)
include:
0.31 g/t Au & 18.7% Cu from Pionggu;
170 g/t Au & 3.3% Cu from Sunda Parit; and
5.96 g/t Au, 0.48% Cu from Sunda Parit Jae.
These further outline a mineralised corridor that extends
at least 3km to the west of Tambang Ubi.
Results of the previous quarter’s ground magnetic survey
have outlined a substantial magnetic high near Pionggu
which may indicate the presence of a porphyry copper
gold system.
Ground magnetic survey coverage is to be extended .
Pagar Gunung
The Pagar Gunung prospect comprises skarn-type zinclead
mineralisation, locally with massive sulphides,
hosted by a Palaeozoic volcano-sedimentary sequence in
the west of the South Block. In 1985 JICA (Japanese
International Cooperation Agency) calculated a body of
mineralisation of approximately 800,000 tonnes, at a
thickness of 0.88m, Ag 68 g/t, Cu 0.45%, Pb 1.20%, Zn
4.60%, based on the results of 14 diamond drill holes.
Recent Oropa rock chip sampling (Table 4) returned
significant zinc – lead – silver – copper – gold values in
mineralised calcareous rocks, highlighting the
prospectivity of this area to host further skarn
mineralisation.

2.2 India
Block D-7 Project Chhattisgarh (18%)
Little development occurred during the December quarter,
other than a new judge being appointed to the
Chhattisgarh High court to replace the former judge who
presided over the Block D-7 case, and who retired in
September last year without making a decision.
Oropa’s Indian joint venture partners are endeavouring to
ascertain whether the new judge will be assigned the
Block D-7 matter, and if so when a hearing date may be
set down. General meetings for both Indian companies
(B.Vijaykumar Technical Services Pte Ltd and
B.Vijaykumar Chhattisgarh Exploration Pvt Ltd) are to be
held later this quarter. Oropa’s directors will attend, with
a view to working with the companies to progress the
court hearings in Chhattisgarh, as well as in Andhra
Pradesh regarding the two Krishna River gravels
Reconnaissance Permits.
2.3 Australia
Lake Deborah Gold Project (5% free carried)
Oropa holds a 5%-free carried interest in the Lake
Deborah tenement which forms part of the Golden Valley
Joint Venture with Polaris Minerals NL.
Earlier this month, Polaris Minerals NL announced that a
6,000m, rotary air blast and air core drilling programme
had commenced to test a number of gold and nickel
targets within the Golden Valley, Bullfinch North and
Kawana project areas north of Southern Cross. Targets
being drilled at Golden Valley and Bullfinch North
include the accessible margins of a number of gold and
nickel targets concealed beneath Lake Deborah.
2.4 Project Evaluation
With the protracted delays in India, the Company has
stepped up its evaluation of a number of projects,
primarily advanced coal projects in Indonesia.
With the suspension of the Contract of Work agreements,
as a result of the autonomous laws introduced in
Indonesia in 2001, tenure over prospective land areas is
now issued locally by the Provincial Governments and
Bupatis via Kuasa Pertambangans (“KPs”), which are not
as secure as the former CoWs. Consequently, a
considerable amount of legal due diligence has to be
undertaken regarding new projects of interest.
A number of projects were evaluated during the Quarter,
most of which were not pursued, although discussions are
continuing with several Indonesian parties.
