Kula Gold Limited (ASX:KGD) (“ Kula ” or “ the Company ”) is pleased to provide additional assay results from development drilling at the Kulumadau deposit at the Woodlark Gold Project (Woodlark) in joint venture with Geopacific Resources (ASX:GPR).
Drilling around the Kulumadau West deposit targeted depth extensions of the mineralisation with success. Results returned strong zones of high-grade mineralisation within 100 metres of the base of the 2012 pit design, increasing certainty around inferred mineralisation identified in historic drilling.
Drilling to the north of the Kulumadau East deposit continued to return broad zones of near-surface mineralisation, which remains open along strike and at depth.
Ongoing development drilling at Busai has confirmed the presence of broad gold intercepts below the Busai Main deposit. These results complement previously released intersections and confirm the continuation of gold mineralisation below the 2012 pit design.
Depth extensions at the Kulumadau West deposit
Kulumadau West is the main area of the Kulumadau deposit, characterised by broad, strong zones of gold mineralisation. This mineralisation is generally associated with cataclaisite breccias and related clay alterations.

Recent drilling at Kulumadau West aimed to define depth extensions to the mineralisation and to improve the confidence in inferred resources below the base of the 2012 pit design. Results have confirmed and extended the mineralisation which remains open at depth (Figure 1 and Figure 2). The depth of the 2012 pit design varies between 130 to 150 metres, with the recent results within less than 100 metres of the proposed pit floor.
The high-grade nature of the Kulumadau West deposit’s central zone can clearly be seen in the longitudinal section (Figure 2) with impressive historical results including:
-
11m @ 36.3 g/t gold
-
13m @ 32.42 g/t gold
-
36m @12.52 g/t gold
-
48m @ 10.39 g/t gold
-
52m @ 4.72 g/t gold
Drillhole KU17DD011, drilled below the proposed 2012 pit outline, intersected 18m @ 10.29g/t gold from 231m , confirming the high-grade, down-dip continuity of Kulumadau West mineralisation.
New results are marked with the yellow labels. Mineralisation remains open at depth.

Kulumadau East
Previous results to the north of the Kulumadau East deposit were announced on 21 March and 15 June 2017 with new results demonstrating continuity. New significant intercepts include:
-
22m @ 2.8 g/t gold from 53m
-
30m @2.08 g/t gold from 28m
The grades and style of mineralisation are consistent with the Kulumadau East deposit. Mineralisation remains open along strike and at depth, with further drilling underway to test the depth and strike potential of the mineralisation.
Mineralisation in this area falls outside the current Resource and Reserve inventory and is approximately 100m northeast of the 2012 proposed East Kulumadau pit boundary as seen in the drillhole location plan Figure 3.
Mineralisation at Kulumadau East is “blind”, covered at surface by a thin layer of soft coronus material (limestone). The coronus covers a large portion of the island and has hindered exploration in the past. Modern geophysical techniques present a significant opportunity to unlock the exploration potential at Woodlark by targeting under the coronus, similar to the Kulumadau East mineralisation.

Drilling and results at the Busai deposit
Recent drilling was designed to test the potential for strike and down dip extensions of gold mineralisation at Busai, focusing primarily on the Busai Main portion of the deposit. Interpretation of earlier drilling indicated potential for the mineralisation to continue at depth. These drill results confirm the continuity of mineralisation up to 70 metres below the current pit design.
Geological logging has identified a correlation between higher gold grades and complex, multiple phases of breccia development.

Gold grades are higher where brecciation is accompanied by cherty haematite, haematite alteration, quartzcarbonate veining and particularly the presence of minor base metal sulphides such as galena, sphalerite and chalcopyrite. Modelling of the breccias can then be used to predict the orientation of the gold zones.
Modelling has indicated a strong possibility for the mineralised system to persist down dip as shown in Figure 4 below.

(Geological interpretation from GPR)
Diamond hole BS17DD018 was drilled to test for continuity of complex mineralised breccias down dip from previously announced gold mineralisation intersected in BS17DD007. The hole successfully intersected strongly mineralised breccia at predicted depths.
Recent diamond drilling beneath the Busai Main deposit confirms the down-dip continuity of gold mineralisation and remains open down dip. Figure 5 represents an oblique section of drilling and shows both down-dip and downplunge potential for additional mineralisation.

Shallow RC drilling in the northern portion of Busai Main, designed to test for possible extensions of gold deposited at the unconformity between underlying volcaniclastics and much younger coronus marine sediment cover, continued to define relatively thin zones of gold mineralisation.
The location of recent drillholes is indicated on the drillhole location plan in Figure 6.

Background on the Woodlark Island Gold Project, PNG
Kula Gold Limited has advanced its Woodlark Island Gold Project to the point where it is permitted and ready to progress to the next stage. The Project is located 600 kilometres east of Port Moresby in the Milne Bay Province, Papua New Guinea.
Kula’s Joint Venture Partner Geopacific Resources Limited is funding the next $8 million expenditure to advance the gold reserves to a target of 1.2 million ounces of gold to earn additional equity in the Project.
The Project has excellent upside potential through the conversion of Inferred Resources and numerous nearby exploration targets within a short distance of the proposed process plant location.
The Resource Estimates for the Kulumadau and Busai Deposits were re reported and released on 31 January 2017 in accordance with JORC 2012. The estimates for Munasi and Woodlark King have not been re reported in accordance with JORC 2012, as there has been no additional work within these deposits since the previous estimate.
Kula Gold’s Feasibility Study, based on a JORC 2004 Ore Reserve of 766,000 ounces and a gold price of US$1200/ounce, defined a Project with a mine life of nine years, three open pit mining areas and a 1.8Mtpa gravity and carbon in leach plant (KGD ASX release 27 September 2012).
The Company’s 95% owned subsidiary, Woodlark Mining Limited, has been granted the Environment Permit and the Mining Lease for the Project.

Appendix B: JORC Code, 2012 Edition – Table 1
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| CRITERIA | JORC CODE EXPLANATION | COMMENTARY |
|---|---|---|
| Sampling techniques |
Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
Sampling was conducted using diamond drilling (DD) or RC drilling. Sampling of the diamond drilling comprised half core samples taken based on lithological, alteration, and mineralisation breaks observed in geological logging. RC samples were collected on a 1m interval with approximately 2kg collected from a riffle splitter. Samples were sent for fire assay gold and four-acid multi-element analysis by ICPMS method. Blank, duplicate, and standard samples were inserted in at various intervals based on Geopacific’s QAQC procedure to ensure assay results are representative and repeatable. |
| Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 50gm charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. |
Core was cut in half using a core saw. Where core competency was low, whole core was wrapped in plastic clingfilm to help maintain integrity of the sampled interval while being cut. RC samples of approximately 2kg were collected on 1m intervals. Samples were prepared on the on-site sample prep laboratory operated by ITS Pty Ltd PNG (Intertek Services Ltd). Standard preparation of samples is to crush ~2kg through a jaw crushed, with a blank bottle wash between each sample. Crushed sample is then transferred to a LM-2 pulveriser for reduction to pulp. A 150gm pulp sample is split from the master sample and submitted for analysis. Coarse reject material and pulps are bagged and stored on site for future reference. Samples were sent for fire assay gold analysis using a 50g charge, as well as multi-element analysis using multi-acid digest with ICP finish at Intertek’s Townsville laboratory. |

| CRITERIA | JORC CODE EXPLANATION | COMMENTARY |
|---|---|---|
| Drilling Techniques |
Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
Hole with an RC suffix were drilled by Reverse circulation drilling (RC), using a 139mm hammer. Holes with a DD suffix were drilled PQ or HQ diameter triple tube. All core is oriented using Reflex digital ori tool for all core diameters. Holes with a RD suffix were PQ or HQ diamond drill holes with a RC pre-collar |
| Drill Sample Recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. |
Core recovery is recorded by measuring the core recovered from the drill hole against the actual drilled metres. RC samples are weighed for each metre and assessed for recovery, contamination and effect of water if present. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples. |
Triple tube barrel for diamond drilling plus closely monitored drill mud regime. Short drill runs used in areas of broken ground. RC drilling on 1 metre basis using cemented pvc casing to 12m to ensure tight collar seal and minimise outside circulation. |
|
| Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
Sample recovery data shows good recovery throughout the drill holes, consistently above 90%, and as such there is no sample bias introduced because of sample recovery. |
|
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. |
All drill core and chips was geologically logged by Geopacific geologists using Geopacific logging procedure. Geotechnical logging of Rock Quality Designation (RQD), hardness, degree of fracturing and weathering is undertaken by Geopacific staff using Geopacific’s logging procedure. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. |
Drill core and chips was logged both qualitatively (e.g. lithology, alteration, structure, etc.) and quantitatively (e.g. veining and mineralisation percentage, structural orientation angles, etc.). Drill core is photographed both dry and wet and is stored in plastic core trays in our exploration core yard. |
|
| The total length and percentage of the relevant intersections logged. |
All holes are logged their entire length. |

| CRITERIA | JORC CODE EXPLANATION | COMMENTARY |
|---|---|---|
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. |
Core is halved, with one half sent for sample preparation and analysis. The remaining core is stored in the core trays on site. |
| If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. |
RC samples weighed, and if dry, riffle split using a three-tier system generating a collective 12.5% split of the original metre sample for analysis. In areas of un-mineralised material, a 4-metre composite is taken by 25% splitting each component 1m sample and combining for a single sample for submission. Residual original split material is reserved should anomalous values be encountered and individual metre samples be required. Wet samples are placed in a clean container, mixed and spear sampled, mixed again and spear sampled, with resultant sub sample mixed and spear sampled again for submission. |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
Samples are crushed to a nominal 2mm by a jaw crusher, with the whole sample pulverised and then split; one 150gm sample for submission with residue stored on site. |
|
| Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. |
Field blank, duplicate, and standard samples are introduced to maximise the representivity of the samples. |
|
| Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling. |
Field duplicates are inserted in accordance with Geopacific’s QAQC procedure at a nominal 1 duplicate in every 20 samples which is in line with industry standards. |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. |
Sample sizes are appropriate to the grain size of the material being sampled. |
|
| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. |
Fire assay Au and four-acid digest ICP analysis are thought to be appropriate for determination of gold and base metals in fresh rock, and are considered to represent a total analysis. |
| For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. |
No results from geophysical tools, spectrometers, or handheld XRF instruments are reported in this release. |

| Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
Field and lab blank, duplicate, and standard samples were used in the drilling. Results from these QAQC samples were within the acceptable ranges. |
|||
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. |
Significant intersections were inspected by senior geological staff. |

| Discuss any adjustment to assay data. | No adjustments were made or required to be made to the assay data. |
|||
| Location of data points |
Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. |
Drill hole collars were located using a total station surveying instrument. Downhole surveys are recorded as being captured by single shot downhole camera |
||
| Specification of the grid system used. | Coordinates are recorded in PNG94 geodetic system |
|||
| Quality and adequacy of topographic control. | LiDAR survey data obtained over the licence area, tied in to total station collar readings provide sub- metre accuracy. |
|||
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. | Drilling reported in this release relates to infill drilling within the Kulumadau West, Kulumadau East and Busai deposits. Existing drilling within the defined deposit area is nominally spaced 25m x 25m, closer in some areas. |
||
| Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. |
Drilling results released in this announcement indicate new areas of unrecognised mineralisation that may or may not add to a future resource estimation. Data points are somewhat isolated from surrounding information and may require additional drill holes to support interpretations and subsequent inclusion in future resource estimations. |

| CRITERIA | JORC CODE EXPLANATION | COMMENTARY |
|---|---|---|
| Whether sample compositing has been applied. | No composite sampling in announced results. | |
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. |
Current interpretations of the mineralised zones in all areas indicate that the orientation of the drill holes has achieved unbiased sampling of the structures. |
| If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
An interpretation of the mineralisation has indicated that no sampling bias has been introduced. |
Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
| CRITERIA | JORC CODE EXPLANATION | COMMENTARY |
|---|---|---|
| Mineral tenement and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
Kula Gold Ltd has executed a Joint Venture agreement with Geopacific Resources Limited (ASX:GPR) where GPR can up to a 75% interest by spending AUD$18.65m over three tranches. In Tranches 1 and 2, GPR must spend AUD$8m and complete 15,000m of diamond drilling within the first two years to earn an initial 35% interest in operating company WML. Should GPR delineate a Reserve >1.2M Oz Au within the two-year period it will be deemed to hold a 51% interest in WML. GPR can increase its ownership to 60% of WML by completing the earn-in expenditure (Tranche 3) without delineating the Reserve target of 1.2M Oz Au. Should that target be met as part of Tranche 3 expenditure, GPR will be deemed to have earned a 75% interest in WML. |

| Geology | Deposit type, geological setting and style of mineralisation. |
Most of Woodlark Island is covered by a veneer of Plio-Pleistocene limestones (coronus) of variable thickness with associated marine clays and basal conglomerates. A central elevated portion of the island (horst structure) contains Miocene volcanic rocks intruded by late stage, high K porphyritic intrusives and contains the known historical mines. Gold mineralisation within the Woodlark Island Gold Project is principally hosted by andesites and their sub-volcanic equivalents within the Miocene age stratigraphic unit known as the Okiduse Volcanics. The mineralisation is variously associated with lodes, quartz veins, stockwork zones and breccias developed within proximal phyllic and marginal propylitic alteration envelopes regionally associated with intrusive breccia complexes. Gold mineralisation is consistent with low sulphidation, base metal carbonate, epithermal systems typical of the south-west Pacific. |
| Drill hole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collaro elevation or RL (Reduced Level – elevationabove sea level in metres) of the drill hole collar o dip and azimuth of the holeo down hole length and interception deptho hole lengthIf the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
See Appendix A, Table 1. |
| 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. |
No top-cuts were used in the reporting of these significant intercept. The interval selected using a cut off value 0.5g/t Au, a maximum of two meters of internal dilution and were calculated using weighted averaging. |

| CRITERIA | JORC CODE EXPLANATION | COMMENTARY |
|---|---|---|
| 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. |
Shorter intercepts of higher grade within larger reported intercepts are subsequently highlighted within the summary drilling table. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
N/A | |
| Relationship between mineralisation 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 (e.g. ‘down hole length, true width not known’). |
Information from other drilling in the area as well as geological mapping indicate that the downhole intervals may be close to the true width, but more structural information is needed to determine the exact orientation of the mineralised zones. |
| 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. |
Diagrams relevant to the report content are included in the body of the 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 Exploration Results. |
Refer to Appendix A, table 1. |
| Other substantive exploration data |
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. |
