Papua New Guinea Operations
The Muller (EL 2356) renewal Warden’s Court Hearing has been postponed until later in 2018 following discussions with the PNG Mineral Resource Authority, Chief Mining Warden. The postponement is due to the ongoing logistical and security issues in the Southern Highlands caused by the 7.5 magnitude earthquake and significant aftershocks. The Mineral Resources Authority will advise a revised date in due course.
The proposed Muller and Bulago exploration programs were also deferred after the earthquake and will be undertaken later in 2018, after the wet season.
Aimex Geophysics (Non-Exec. Director Swiridiuk) completed an Aster satellite imagery study for EL2356 Muller Range. The study delineated a total of 37 Aster targets (up to 31 Ha in size) that were recommended for future geochemical sampling and geological mapping. There were 17 anomalies at the Tingi Block, 13 at Baia and 7 at Cecelia. Lineament and volcanic structural features were plotted (over areas not obscured by cloud cover). Aster Targets are areas which have potentially been altered by mineralising fluids. The report is attached as Appendix 1.

| Data aggregation methods |
o | 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. |
Historical sampling results show data aggregation if applied in trench/channel samples etc. No top cuts have been applied. They are continuous channel samples and so are stated as continuous weighted assay results (length x grade summed for each sample/sum of total length). |
||||||
| 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 |
If this is occurring, it is stated in the text. | ||||||||
| o | The assumptions used for any reporting of metal equivalent values should be clearlystated. |
No metal equivalent values are reported. |
|||||||
| Relationship between |

| mineralisation widths & intercept lengths |
o o |
If the geometry of the mineralisation with respect to 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(e.g. 'down hole length,true width not known'). |
No drilling undertaken. |
|---|---|---|---|
| Diagrams | o | 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. |
Appropriate maps and any sample results are included. |
| Balanced reporting |
o | 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 Exploration Results. |
Reporting of historical Exploration Results is included herein. |
| Other substantive exploration data |
o | Other exploration data, if meaningful and material should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances |
All relevant meaningful exploration data relating to Tingi has been included in this release. |

1.0 EXECUTIVE SUMMARY
The Muller Range exploration licence in the Western and Southern Highlands Provinces is about 150km south east from the Ok Tedi mine (Figure 1). The tenement is split into three separate areas which include the northern Tingi Block, central Baia Block and southern Cecelia Block (Figure 2).
The northern Tingi Block (16 sub-blocks; Figure 2) contains the Tingi, or Tingi Valley prospect with porphyry CuAu-Mo mineralisation, polymetallic (Au-Cu-Pb-Zn-Ag) skarns, breccia hosted basemetal mineralisation, fault controlled massive sulphides and gold veining.
The central Baia Block (13 sub-blocks; Figure 2) contains the large porphyry Baia prospect, with a copper-goldmolybdenum in soils anomaly and small skarns present. Historical exploration by Barrick confirmed Baia as a weakly mineralised porphyry system dominated by propylitic and structurally controlled phyllic alteration.
Within the southern Cecelia Block (27 sub-blocks; Figure 2), the northernmost Cecelia prospect has historical outcrop rock samples of 0.62% copper. Strong argillic and propylitic alteration has been covered by recent agglomerate with pebble dykes being common. Two rock chip samples taken between years 1986-88 are of advanced argillic alteration returning 0.616 g/t gold and 710 ppm copper.

This report focusses on utilising Aster satellite imagery to map lineaments and circular volcanic features; and to define targets related to clay alteration (i.e., minerals such as kaolinite, dickite, smectite are known to be associated with gold and copper deposits) and anomalous jarosite/hematite iron oxides. Historical surface geochemistry has been reviewed to highlight anomalous gold which may be related to some of the selected Aster target areas in the Tingi Block.
A total of 37 Aster targets (17 Tingi Block: 13 Baia Block targets: 7 Cecelia Block) were selected in size up to 31 Ha. Lineament and volcanic structural features have been plotted over areas not obscured by cloud cover in the Aster scenes. Target areas have potentially been altered by mineralising fluids and are recommended for future geochemical sampling and geological mapping.

2.0 HISTORICAL EXPLORATION
The Tingi Valley Copper-Gold Porphyry Prospect area is covered by Mesozoic sediments (mudstone, siltstone, sandstone) overlain by early Tertiary limestone intruded by Tertiary–Pleistocene monzonite and diorite stocks (Figure 3). Within the prospect, several small diorite stocks and sill complexes intrude Darai Limestone and underlying Mesozoic sediments. Copper-gold mineralisation appears to be associated with these intrusive bodies. In the early 70s, CRA Exploration and BP completed regional stream sediment sampling. In 1991 Kennecott interpreted airborne magnetics to delineate two separate porphyry targets beneath Darai Limestone and completed soil sampling and mapping, receiving spot gold assays of 4.9 g/t gold, 30 g/t gold and 12 g/t gold. Wantok Mining completed channel sampling in 1996, delineating anomalous copper within andesite porphyry and brecciated massive sulphide skarn. Carson-Pratt Exploration completed mapping and sampling in 2004 after which they recommended additional follow-up on the intrusive/limestone contact for possible gold bearing veins. It is expected that analysis of satellite Aster imagery will help define structures and zones of alteration related to mineralisation and porphyry deposits.
In 2016, historical data from for the Baia and Cecelia prospects generated by Barrick were compiled into a number of diagrams to analyse ridge and spur soil geochemical samples together with interpreted lithology, fact mapped geology and airborne geophysics. Barrick confirmed Baia as a weakly mineralised porphyry system dominated by propylitic and structurally controlled phyllic alteration. Copper in soil geochemistry demonstrates a 900m x 600m wide anomaly with a typical zinc/lead halo around the copper system. Dominant alteration is propylitic, with structurally controlled phyllic and patchy un-mineralised potassic alteration. A total of seven skarn targets, identified previously by Aimex Geophysics, are related to near surface magnetic bodies at the contact between limestone and intrusive. The Aster satellite imagery analysis in this report helps define additional alteration targets which may also be related to previously unknown mineralisation within the tenement block.
The Cecelia prospect is defined from stream sediment (> 250ppm Copper) sampling and rock chip sampling by Kennecott in 1970. Best results included in rock float samples included 0.18% copper within granodiorite with bornite-chalcopyrite in altered intrusive in the upper reaches of the prospect. Vuggy quartz-alunite-pyrophyllite rock has been described from the upper reaches of Cecelia. High sulphidation epithermal advanced argillic alteration, with vuggy quartz - alunite- pyrophyllite is present, but no significant gold noted in follow-up. Strong argillic and propylitic alteration, which has been covered by recent agglomerate and pebble dykes are common, indicating a probable buried porphyry copper-gold-molybdenum target. Additional targets defined from the Aster satellite imagery in this report may indicate near surface alteration from underlying hydrothermal events related to mineralisation. Volcanics throughout much of the tenement Block (Figure 3) has been tracked/mapped from airborne magnetic imagery.

3.0 ASTER SATELLITE ACQUISITION AND IMAGERY
A number of Aster satellite scenes were searched and acquired from the NASA Earthdata catalogue web site and processed using ERMapper software into numerous images. Short Wave Infared (SWIR) bands (Table 1) are utilised in coloured imagery to help map areas of alteration related to hydrothermal events including porphyry related intrusives, epithermal veins and hydrothermal breccia.
The SWIR sensors on the ASTER satellite failed in April 2007, hence there are only approximately seven years’ worth of captured satellite scenes from around the globe. In the PNG Highlands, cloud coverage is quite extensive year round and no cloud free ASTER images could be found. Satellite scenes were selected on the basis of a minimum amount of cloud cover over the tenement blocks.

4.0 TINGI BLOCK ASTER INTERPRETATION
A number of Aster scenes were downloaded to determine those with least cloud coverage over the Tingi Northern Block. Numerous images were created including the Band 3,2,1 (RGB) scene which is used to define lineaments and structures (Figure 4).
A total of 17 “MR” targets have been selected within the Northern Tingi Block (Figure 4) from image enhancements (Figure 5 to 15) which utilise Short Wave InfaRed bands. These target zones range in size from 0.8 Ha to 31 Ha (Table 2) and are based on potential hydrothermal alteration including clays such as pyrophyllite, dickite, sericite, kaolinite, illite, smectite and montmorillonite. Zones of anomalous jarosite and hematite may indicate areas for skarns and gossans. Lowly anomalous jarosite and hematite can be related to the presence of hydrothermal related clays.

Figure 4: Tingi Block Aster Targets with Historical Gold in Soil Samples
The Abdelsalam Image (Figure 5) is useful for mapping structures in the immediate vicinity of the Tingi Prospect, where soil sampling shows anomalous gold (Figure 10) in the near target MR01. In particular, target MR10 has a concentric halo of anomalous clays and anomalous smectite clays at its centre (Figure 6), indicating a potential porphyry copper-gold target at depth. Other targets in this area include MR12, 13 & 16 which are topographically circular with associated clay alteration (Table 2).
Further west of Tingi, additional targets MR03, 15 & 17 are anomalous in topography and clay alteration.

The “Abdelsalam” Red-Green-Blue false colour image (Figure 5) was created to help map geological volcanic structures and clay anomalies from potential porphyry styles of mineralisation. The “Smectite” image (Figure 6) shows clay style argillic alteration.

The pseudocolour Aster Alunite (Figure 8) image helps define clay styles of alteration in a typical porphyry and epithermal mineralising environment. False colour Red-Green-Blue images including the “Volesky Ratio” enhancement (Figure 9) are used to define possible gossanous material in red and clay alteration as green. MR15 is anomalous along a structure mapped by Kennecott, acting as a possible conduit for mineralising fluids and therefore upgrading this target.

To the north of the Tingi Prospect (Figure 10), target MR14 occurs as a linear vein related feature anomalous in gold in soil samples; and in alunite clays (Figure 11) from Aster imagery. Target number MR05 has a distinct inner halo in Jarosite iron (Figure 12), which may represent gossan float from weathered ore in the phyllic zone. MR06 is topographically anomalous and low in the alunite clays image and also low in jarosite type irons (Table 2).
Numerous lineaments are plotted as mainly occurring in a northwest orientation with some circular volcanic structures surrounding the MR04 and MR14 target areas (Figure 10). The MR07 is an 8 Ha target area, mainly associated with anomalous Hematite iron, possibly gossanous.
To the northeast of the Tingi Prospect area (Figure 13), the MR11 target occurs as an outer halo along an interpreted circular volcanic structure and anomalous in clay alteration (Figure 14). This target may be related to porphyry style mineralisation in a propylitic zone and should be check with ground sampling and mapping.
Other targets in the northeastern area include MR09, which has two discrete topographic anomalies similar to that at the Tingi MR01 target area. The MR08 target area has a circular alunite clay alteration halo along its south-eastern rim (Figure 15) indicating potential for mineralisation beneath an argillic alteration halo.

5.0 BAIA BLOCK ASTER INTERPRETATION
Published geological mapping (Figure 3) and the topographic image (Figure 2) shows the Baia prospect, occurring on the southern side of a partly collapsed strato-volcano. All Aster scenes with SWIR bands in this area have existing cloud coverage; however 13 targets (Table 3) have been defined within the central Baia Block (Figure 16) which has mapped feldspar porphyry in contact with limestone and mudstone. Aster imagery (Figure 18) shows the mapped mudstone and limestone extending throughout the tenement block. A second Aster scene with differing cloud coverage (Figure 17) was used to increase the area of interpretation.
In the southwestern portion of the Baia tenement Block, five Aster Targets (BA05, 06, 07, 08 & 13) occur as anomalous ‘Dickite’ type clay alteration (Figure 18). Targets 05 & 06 have anomalously low jarosite iron (Figure 19).
Target BA03 is a linear clay alteration target with potential forepithermal style mineralisation within mapped limestone. Similarly, BA10 is a linear target within mapped silicate mudstone (Figure 16). BA09, in the southernmost part of the tenement block, occurs as a small topographic feature. Circular targets BA04 and BA11 have a red/blue colour in Figure 18, indicating potential for hydrothermal alteration, as with the smaller target area BA12 (Figure 17). All targets are slightly anomalous in clay/dickite alteration with some anomalously low in jarosite iron. BA01 & 02 occur as small reddish anomalies in Figure 18, indicating potential for alteration and mineralisation at depth.
These target areas are recommended for additional geological mapping and rock sampling prior to further trench sampling and ground geophysics.

6.0 CECELIA BLOCK ASTER INTERPRETATION
Numerous Aster scenes were searched over the larger Cecelia named southernmost tenement block. Although all satellite scenes had significant cloud occurrence, two Aster scenes (Figure 20) were able to be utilised to interpret volcanic structures and alteration within the extensive volcanic pile mapped throughout the tenement block (Figure 3). A number of volcanic circular structures have been identified along with lineaments and six targets (Table 4).
Interpretation was split into the northern area of the Cecelia porphyry copper-gold-molybdenum system (Figures 21 and 22) and the southern area (Figures 23 and 24); which excludes the Mt.Sisa (Figure 20) porphyry/volcano system as it is obscured by cloud cover due to extensive elevation in height (Figure 2).
The Cecelia prospect lies on the contact between Wongop Sandstone and Andesitic Lava. A further 140m south, there exists the CE06 alteration target which is anomalously low in jarosite iron (Figure 22). Within an interpreted volcanic complex, the CE05 alteration Aster target is elongated north-south occurring on the contact between Andesitic Lava and Pyroclastics (Figure 22). CE07 is an area with distinct spotty alteration (Figure 21) and low in jarosite (Figure 22).
Four Targets are interpreted in the southern section (Figure 23) where CE01, 02, 03 & 04 are related to “dickite” clay type alteration. The southernmost target CE02 has a circular halo of anomalous jarosite (Figure 24) and is an priority target for potential mineralisation at depth.
A number of circular volcanic centres were interpreted southwest and southeast of the Cecelia prospect with bedding type structures outlined further south over the cloud free areas of the Aster imagery, between CE01 and CE02 (Figure 20).

7.0 CONCLUSION
A total of 17 Tingi Block targets, 13 Baia Block targets and 7 Cecelia Block targets have been defined from a number of different Aster scenes. Each scene has been processed into numerous coloured images to help map out areas of volcanic circular structures, lineaments and alteration due to potential mineralisation related to porphyry copper deposits, gossanous zones, epithermal gold and hydrothermal breccia systems.
The most common images used for interpretation includes Dickite-Jarosite-Pyrophyllite Ratio (Red-Green-Blue false colour), Haematite Ratio (pseudocolour), Jarosite Ratio (pseudocolour), Alunite Ratio (pseudocolour), Clay Ratio (pseudocolour), ‘Volesky Ratio’ (Re=gossan, Green=alteration, Blue=host rock), ‘Abdelsalam Ratio’ (RedGreen-Blue false colour), ‘Sultan Ratio’ (Red-Green-Blue false colour).
Aster Targets are recommended for future geochemical sampling and geological mapping.
Additional interpretation is recommended to be completed from Landsat, Sentinel-2 and Worldview satellite imagery.
