1. ABOUT COPPERMOLY

Queensland-based copper exploration company Coppermoly Limited (ASX: COY) is focused on exploring for and developing copper-gold deposits. It has two projects, Simuku and Nakru-1, on New Britain Island, Papua New Guinea and another three tenements nearby under application. The Simuku Project has an Inferred Mineral Resource of 200 million tonnes at 0.47% copper equivalent, and a maiden Inferred Resource for the Nakru-1 Project is expected in 2012.

Both the Simuku and Nakru projects are within a four-hour drive from the provincial capital of Kimbe, which has businesses, roads, shops, electricity and a deep water port (refer to Photo 1) that supports the region’s growing oil palm industry. These local services are essential for the future development of Coppermoly’s projects.

Barrick (PNG Exploration), a wholly-owned subsidiary of Barrick Gold Corporation, has notified Coppermoly Limited that it has met the $20 million expenditure commitment under the farm-in agreement on Coppermoly’s tenements on New Britain Island which include Simuku (EL1077), Nakru (EL1043) and Talelumas (EL1445). Therefore Barrick has now earned a 72% stake in these three projects. In accordance with the agreement a joint venture for the exploration of the tenements will now be formed.

2. SIMUKU PROJECT (EL1077)

The Simuku project is within a one-hour drive by 4WD vehicle from existing infrastructure at the provincial capital of Kimbe. Porphyry-style copper-molybdenum-(silver) mineralisation is discontinuously present over an area of about 4.5km by 1.0 to 2.2km.

It is host to an Inferred Resource of 200 million tonnes grading 0.47% copper equivalent (using a 0.30% copper equivalent cut-off) or a higher grade Inferred Mineral Resource of 80 million tonnes grading 0.60% copper equivalent (using a 0.5% copper equivalent* cutoff). It contains 700,000 tonnes of copper, 12,000 tonnes of molybdenum, 12 tonnes of gold and 391 tonnes of silver (or 1.5 billion pounds of copper, 26 million pounds of molybdenum, 0.4 million ounces of gold and 13 million ounces of silver).

A total of 10,248 metres has been drilled in 37 diamond holes. Since the maiden Inferred Resource was announced in 2009, an additional six diamond holes for 4227m were completed. Two diamond drillholes to more than 500m beneath the Inferred Resource will be reviewed with a view to a resource upgrade (refer to Figure 2).

Assay results for BWNBDD0014 show 1,001.9 metres grading 0.24% copper, 60ppm molybdenum and 2.38 g/t silver beneath the Tobarum Prospect. The mineralisation extends to more than 500m below the existing Inferred Resource. Significant results include 16m grading 0.54% copper from 202m depth and 43m grading 0.54% copper from 224m (refer to Table 1).

Further south at the Misili Prospect, BWNBDD0015 was terminated at 686.4m. Highlights include 24m grading 0.75% copper from 292m (refer to Table 2). The copper mineralisation is predominantly within quartz feldspar porphyry and breccia units. Molybdenum intersections including 47m grading 234ppm and 0.32% copper from 451m demonstrates that zones of molybdenum extend from surface trenching to more than 430m deep.

A third deep drillhole BWNBDD0016 beneath the Horseshoe molybdenum prospect was completed to 900m (refer to Table 3). Assays are pending.

3. KULU PROJECT (EL1077)

Drilling at BWNBDD0018 has been completed to 617.2m in the Kulu prospect area. Assay results are pending. The drill hole (refer to Table 4) tested the strongly fractured dioritic intrusive which consistently returned more than 0.2% copper and 20 to greater than 50ppm Molybdenum from channel rock chip sampling. The target zone has at least a 500m strike length delineated from 2010 and 2011 mapping by Barrick.

4. NAKRU PROJECT (EL 1043)

- Nakru 1 Prospect

The Nakru-1 copper-gold system is the most advanced prospect within the Nakru tenement with 27 diamond drillholes completed for 5,928.4m. During 2010, a diamond drillhole through the centre of an untested geophysical chargeability anomaly intersected 213.75m grading 0.92% copper and 0.33 g/t gold from 74.45m. Nakru-1 has an exploration target of 50 to 60Mt grading 0.7 to 0.9% copper within the bounds of the existing drillholes (refer to Figure 5). Further drilling is required to determine the extent of copper and gold mineralisation. Golder Associates have been appointed to review all drillhole data to provide a resource estimate by the second quarter 2012.

In accordance with Clause 18 of The JORC Code the reference to ‘Exploration Target’ in terms of target size and type should not be taken as an estimate of Mineral Resources or Ore Reserves. The statement referring to quantity and grade of the exploration target is based upon exploration results to-date including extensive drilling which has intersected the mineralisation. The potential quantity and grade is conceptual in nature. There has been insufficient exploration to define a Mineral Resource and it is uncertain if further exploration will result in the definition of a Mineral Resource.

Drilling results through an overlying ‘blanket’ of secondary copper enrichment include:

  • 13.55m grading 2.8% copper and 0.23 g/t gold from 74.45m depth

  • Barren dyke at 89m

  • 22.23m grading 1.47% copper and 0.13 g/t gold from 98.75m.

Secondary enrichment has been intersected in four drillholes and further drill testing will help define its tonnage and grade. In hole BWNBDD0008, an epithermal gold vein was intersected with 23.5m grading 1.30% copper and 2.38 g/t gold, including one metre of 4.6% copper, 42 g/t gold and 2840ppm tellurium.

FIGURE 5: Nakru-1 Geophysical image (100m depth) showing chargeability (red areas > 25m) interpreted to be associated with primary copper mineralisation

The last hole drilled completed at Nakru-1 (BWNBDD0013) intersected a number of intervals of copper and gold mineralisation (refer to Table 5) into the “outer” and “marginal” zones of the “breccia pipe” model (refer to Figure 6).

Additional drilling will be required to test for tonnage potential along the ‘eastern extension’ of the Induced Polarisation geophysical anomaly, which plunges at depth (refer to Figure 7).

  • Nakru 4 Prospect

The Nakru-4 prospect is within the northern extent of a 600-metre by 1400-metre historical gold-in-soil anomaly which extends from the south-western portion of the Nakru-1 coppergold system.

Seventeen Wacker or auger soil sampling drillholes at between 5m and 10m deep were completed in April 2011 in an attempt to sample bedrock beneath volcanic ash and soil cover (refer to Figure 9). Results indicate anomalous gold and copper associated with altered bedrock and rhyolite breccia in nine of the holes (refer to Table 7).

The first ever diamond drillhole BWNBDD0017 (refer to Figure 8) intersected 22m grading 0.21 g/t gold and 0.15% copper from 9m. This includes a 1m interval of 1.54 g/t gold and 1.17% copper. The hole is 800m northwest of the Nakru-1 prospect and was completed to a depth of 271.9m to test for anomalous gold and copper mineralisation from the Wacker sampling, gold in surface rock samples and a slightly anomalous ground geophysical chargeability anomaly.

Results confirm the presence of widespread copper and gold mineralisation at depth which warrants further drilling to test for tonnage potential.

The Nakru-1, 2, 3 and 4 prospects occur as a cluster of copper-gold-zinc breccia related mineralisation. The Nakru-1 system exhibits an overprinting of epithermal gold, while both the Nakru-1 and Nakru-2 systems show characteristics similar to volcanogenic massive sulphide deposits (refer to Figure 8). Further drilling will be required to define the extent of mineralisation within these four prospect areas as well as test the other geophysical and geochemical targets.

5. ESK TROUGH PROJECT

Coppermoly Limited has signed an agreement with ActivEX Limited (ASX: AIV) to farm-in to the Esk Trough Project in south-east Queensland (refer to Figure 9), a four-hour drive north-west of the state capital of Brisbane. Coppermoly can earn a 51% interest by spending $3 million over three years and can further elect to advance its interest to 70%.

The Esk Trough Project has advanced exploration prospects to be drill tested with 2000 to 3000 metres of RC drilling, expected to begin in April. Ground geophysical Three Dimensional Induced Polarisation surveys are expected to begin in February. The project has significant historical drill hole intersections which are accessible by roads and track from existing infrastructure towns within a half-hour drive by 4WD vehicle (refer to Figure 10).

Peter Swiridiuk MANAGING DIRECTOR

The information in this report that relates to Exploration Results and Inferred Resources is based on information compiled by Peter Swiridiuk, who is a Member of the Australian Institute of Geoscientists. Peter Swiridiuk is a consultant to Coppermoly Ltd and is employed by Aimex Geophysics. Peter Swiridiuk has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2004 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’. Peter Swiridiuk consents to the inclusion in the report of the matters based on his information in the form and context in which it appears.

Notes:

  • All stated intersections are weighted assay averages ([Sum of each total interval x grade] / Total length of intersection).

  • Drillhole samples from drillholes were transported to the camp site then to the town of Kimbe where they were logged, orientated and sampled between 1m and 2m intervals from core split by saw. The split samples were then freighted to either Intertek in Lae (PNG) for sample preparation. Samples were dried to 106 degrees C and crushed to < 2 mm. Samples greater than 2kg were rifle split down to 1.5kg and pulverised to 75 microns. The final 300g sized pulp samples were then sent to Intertek laboratories in Jakarta for geochemical analysis. Intertek analysed for gold using a 50g Fire Assay with Atomic Absorption Spectroscopy finish. Other elements were assayed with ICPAES Finish. Copper values greater than 0.5% were re-assayed. Intertek laboratories have an ISO 17025 accreditation. Unused half core is stored in sheltered premises in the town of Kimbe.

  • Quality control and quality assurance checks on sampling and assaying quality were satisfactory.

  • BWNBDD (Barrick West New Britain Diamond Drillhole) Series Drill Core is PQ, HQ and NQ in size with core recovery predominantly greater than 93%.

  • Co-ordinates are given in UTM Zone 56, AGD66 Datum.

  • Mineralised intersections are quoted as down hole widths.

  • Mineralisation at Simuku consists of copper, molybdenum, gold and silver.

  • Copper equivalent values have been calculated as (Cu + (7.6 x Mo) + (7818 x Au) + (101.3 x Ag))

  • The copper equivalent values for intersections are quoted in addition to individual metal values, as they provide the most meaningful comparisons between different drill holes and trenches. The copper equivalent value will vary with the metal price.

  • Copper Equivalent* is the contained copper, molybdenum, gold and silver that are converted to an equal amount of pure copper and summed (based on assays of mineralised rock and actual metal prices). It is used to allow interpretation of the possible theoretical ‘value’ of mineralised rock, without consideration of the ultimate extractability of any of the metals.

  • Island Arc related porphyry copper – molybdenum - gold – silver deposits such as Simuku typically recover those metals subject to prevailing metal prices and metallurgical characteristics.

  • The ASX requires a metallurgical recovery be specified for each metal, however, no test work has ever been undertaken at Simuku and recoveries can only be assumed to be typical for Island Arc porphyry copper – molybdenum –gold –silver deposits.

  • It is the Company’s opinion that each of the elements included in the metal equivalents calculation has reasonable potential to be recovered if the project proceeds to mining.
