ASX Announcement
30 March 2020
ASX Code: COY
Trenching identifies high grade Cu-Zn mineralisation at the Mt Nakru Project, Papua New Guinea
Highlights
-
Trenching at the Nakru 3 prospect, on the Mt Nakru Project in Papua New Guinea, has identified high-grade copper-zinc-gold-silver mineralisation, with Trench NK19_T14_2B returning:
-
6m @ 2.23% Cu, 8.23% Zn, 0.61% Pb, 2.0g/t Au & 237g/t Ag
-
The occurrence of high-grade copper-zinc-gold-silver mineralisation at Nakru 3 complements the occurrence of high-grade copper-zinc mineralisation at the Nakru 2 North-West Prospect[1 ] reported in December 2019, with Trench NK19_T02 returning:
-
11m @ 4.13% Cu, 9.04% Zn, 0.29g/t Au & 47g/t Ag[2]
-
The occurrences of high-grade massive sulphide copper-zinc mineralisation at both the Nakru 2 North-West and Nakru 3 prospects demonstrate the potential of the Mt Nakru Project to host significant deposits of high-grade copper-zinc mineralisation to complement the Inferred Mineral Resource at the Nakru 1 prospect, which is estimated as 35Mt @ 0.73% Cu, 0.25g/t Au & 1.45g/t Ag, including 7.03Mt @ 1.0% Cu and 0.28g/t Au, which is classified as Indicated (JORC 2012)[3]
-
Ground electromagnetic (EM) geophysics surveys have recently been completed at Nakru 2 North-West and Nakru 3, with the objectives of defining the strike length of the high-grade copper-zinc-gold-silver mineralisation and providing additional targets for follow up drilling.
-
The results of the ground EM surveys will be released when final interpretations of the EM data have been received.
Coppermoly Limited ( ASX:COY or “the Company” ) is pleased to announce the results from a trenching program completed at the Nakru 3 prospect on the Mt Nakru Project (EL1043), on the island of New Britain, Papua New Guinea (Figure 1). The trenching program at Nakru 3 has discovered a sub-cropping 6m width of high-grade copper-zinc-gold-silver mineralisation, with associated anomalous lead. In addition to the high-grade copper (2.23%) and zinc (8.23%), the 6m intersection in trench NK19_T14_2B, also returned 2g/t gold, which is extremely encouraging.

The Company is not aware of any new information or data that materially affects the information included in the referenced ASX announcement and confirms that all material assumptions and technical parameters underpinning the estimates in the relevant market announcement continue to apply and have not materially changed.
The high-grade copper-zinc-gold-silver mineralisation located in trench NK19_T14_2B at Nakru 3 is also exposed in a creek bed and trends under the flank of the neighbouring hill, making it difficult to tell from surface the strike length of the high-grade mineralisation. The high-grade copper-zincgold-silver mineralisation is hosted in felsic volcanics, within a zone of strong pyritic alteration.

Coppermoly’s Managing Director Dr. Wanfu Huang commented that the trenching program was extremely successful, identifying high-grade copper-zinc-gold-silver mineralisation at both the Nakru 2 North-West and Nakru 3 prospects, significantly enhancing the prospectivity of the Mt Nakru Project.
“Within the last year we have discovered two new sites of significant widths of high-grade copperzinc-gold-silver mineralisation at Nakru 2 North-West and Nakru 3 which strongly complement the existing Inferred Mineral Resources we have defined at the Nakru 1 and Nakru 2 prospects,” he said.
“Our objective at Nakru 2 North-West and Nakru 3 is to now determine the strike length of these sites of new high-grade mineralisation and we have recently completed ground electromagnetic surveys, with the goal of tracing the mineralisation along strike at both Nakru 2 North-West and Nakru 3.” Dr. Huang said.
Nakru 3 Prospect Trenching Program
The Nakru 3 prospect is located approximately 800m north-east of the Nakru 1 Inferred Mineral Resource and 2.3km east of the Nakru 2 North-West prospect. Historical surface geochemistry sampling at Nakru 3 showed several areas with elevated Cu and Zn values which provided the encouragement to proceed with trenching at Nakru 3. Fourteen trenches for a total of 835m were constructed in the general area around the Nakru 3. Trenches NK19_T14_2B, NK19_T12_2 and NK19_T12_3 exposed copper-zinc-gold-silver mineralisation, with exposed pyrite-silica-clay alteration zones and extensive quartz stockwork veining, all with above background Cu values. The area of alteration extends beyond the limits of the area which was trenched. The thickest and highest-grade copper-zinc-gold-silver mineralisation was 6m of mineralisation exposed between 63-69m along trench NK19-T14_2B.
During the trenching campaign completed in October-November 2019, several lenses of massive sulphide were uncovered. The massive sulphides occur within consistent zones of steeply dipping silica-rich rhyodacite breccias containing disseminated sulphides. The mineralisation located to date can be generally described as a combination of structurally controlled and ‘stratabound’ hydrothermal felsic breccia with polyphase quartz stockwork mineralisation. Alteration is dominated by silica-clay-pyrite with commonly disseminated copper and zinc sulphides.
Location details for the trenches are given in Table 1 and shown in Figure 2. Summary assay results from the trenches are given in Table 2. Samples were collected along all of the trenches and were initially analysed on site with a hand-held portable XRF. Samples with indications of copper and zinc above 1,000 ppm were then dispatched to Intertek Laboratories in Lae and Townsville for 34 element analysis by ICP-OES. Full assay results are given in Appendix 1.
The geological setting for Nakru 3 is generally similar to the nearby Nakru 1 and 2 deposits, suggesting it is a felsic dome system which appears to have been structurally dissected post mineralisation. However, the mineralisation at Nakru 3 is much more massive in nature in comparison to the mostly disseminated mineralisation at Nakru 1 and 2.
Due to the outstanding results obtained from the trenches completed at the Nakru 2 North-West and Nakru 3 prospects in late 2019, follow-up work was expedited. Ground electromagnetic (EM) geophysical surveys have been completed at both the Nakru 2 North-West and Nakru 3 prospects, with the objective of determining the strike extent of the high-grade copper-zinc-gold-silver mineralisation at both prospects.
Summary of Trenching Results from the Mt Nakru Project
The Mt Nakru Cu-Au project (EL 1043) comprises two known deposits, Nakru 1 and Nakru 2, which are 1.5 km apart. Nakru 1 hosts an Indicated Mineral Resource of 7.03Mt @ 1.00% Cu, 0.28g/t Au, and 28.02 Mt Inferred Mineral Resource at 0.66% Cu and 0.25 g/t Au (JORC 2012). Nakru 2 hosts an estimated Mineral Resource of 6.33Mt @ 0.85% Cu, 0.04g/t Au & 2.34g/t Ag, which has been classified as Inferred in accordance with JORC 2012[4] . High-grade copper-zinc mineralisation zones have also been exposed in sub-crop at both the Nakru 2 North-West and Nakru 3 prospects.

*NK19_T14_2B is a deeper trench of approximately 1.5 to 2.0m greater depth that was dug in this same location as trench NK19_T14_2 after initial samples from trench NK19_T14_2 were collected. 6m of highgrade mineralisation was resampled and assayed between the 63-69m section.
Local geology at Mt Nakru is dominated by a rhyolitic ‘flow-dome’ complex that overlies Upper Eocene to Upper Oligocene age andesitic and basaltic volcanics. A thin blanket (2-8m) of Pleistocene to Recent tephra covers the local area. Copper-gold mineralisation at Nakru 1 and Nakru 2 and is marked by surface geochemical anomalies and strong chargeability anomalies in Induced Polarisation (IP) data. Most mineralisation is veinlet and disseminated style hosted by strongly quartz-sericite-pyrite altered volcanic breccias, with some thin veins of massive sulphide. More significant widths of massive sulphide mineralisation occur at Nakru 2 North-West and Nakru 3, as opposed to the more disseminated mineralisation at Nakru 1 and Nakru 2. Textural evidence indicates that mineralisation was emplaced at a high level in a submarine environment.
At Nakru 2 North-West the best result was from trench NK19_T02 which returned 11m @ 4.13% Cu, 9.04% Zn, 0.29g/t Au & 47g/t Ag. At Nakru 3 the best result was from trench NK19_T14_2B which returned 6m @ 2.23% Cu, 8.23% Zn, 0.61% Pb, 2.0g/t Au & 237g/t Ag. Both results from the Nakru 2 North-West and Nakru 3 prospects are extremely encouraging, with the results at Nakru 3 being especially interesting due to the occurrence of 2g/t gold with the 6m width of high-grade copper-zinc mineralisation.
With two defined mineral resources (Nakru 1, Nakru 2) and two sites of high-grade copper-zincgold-silver mineralisation (Nakru 2 North-West, Nakru 3), the overall Mt Nakru project is emerging as a highly mineralised area with significant potential.

•Exploration licence, EL1043 renewal was granted by the Independent State of Papua New Guinea on 7thDecember 2018 for a 2-year period. The tenement covers 47.82 km2 (14 sub-blocks) and lies approximately 60km southeast of the town of Kimbe which is the capital of West New Britain Province. The tenement is held by Copper Quest (PNG) Ltd which is a wholly owned subsidiary of Coppermoly Limited. Barrick still have a nominal 28% interest in the licence. The tenement lies within an area owned by traditional landowners whom support the project through the government regulated warden hearing process. |

| Data aggregation methods • In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
•Semi-quantitative pXRF analyses were conducted on all samples using an Olympus Vanta instrument. This was used for internal purposes to confirm presence of anomalous elements of interest, in particular Cu and Zn from which samples were selected for dispatch for assay at the laboratory. •Trench intercepts are reported above 0.1%Cu and 0.1% Zn with a maximum of 5 metres to define an average result in low grade areas. High grade intercepts are reported on a 1m basis. |
| Relationship between mineralisati on widths and intercept lengths • These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
•Not Applicable |
| Diagrams • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
•Maps with location of trenches and samples within tenement context can be seen in accompanying report |
| Balanced reporting • Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of |
•The full breadth of assay data is represented. All other intervals were analysed using a pXRF and did not record any results above 1,000ppm for Cu or Zn and therefore not dispatched for assay. |
