The Board of Geopacific Resources Limited (Geopacific) is pleased to announce an update on the development potential of the Kulumadau deposit at the Woodlark gold project (Woodlark).
The current resource for Woodlark is 45.1 million tonnes @ 1.50g/t of gold for 2.12 million ounces (Table 1), including a reserve of 10.9 million tonnes @2.20g/t of gold for 766,000 ounces (Table 2) .
Geopacific is assessing the current resources at Woodlark to establish which areas hold the best potential to convert a further 500,000 ounces of gold from resources into reserves in order to deliver an overall reserve of 1.2 million ounces in accordance with the earn-in transaction to acquire up to 80% of the project from Kula Gold Limited (Kula).
The ongoing assessment began with a detailed evaluation of the Kulumadau Resource area, which is detailed in this release.
Geopacific’s assessment of the Kulumadau deposit has identified significant potential to increase both resources and reserves.
The assessment used 3D modelling to demonstrate how the resources at Kulumadau are situated in relation to existing pit designs. This shows substantial inferred mineralisation surrounding the pits and includes an area with a core of >5g/t Au. These resources may be amenable to conversion with a combination of improved economics, selected drilling and updated pit designs.
- Geopacific has prepared a 3D fly through video showing the grade and resource categories of the mineralisation in relation to current pit designs at Kulumadau, with an update on the potential of the Busai deposit to follow shortly.
The video is available on Geopacific's website www.geopacific.com.au.

Geopacific Managing Director Ron Heeks said:
”Woodlark is a development project with significant exploration upside – it’s a game changer for Geopacific.”
“Our immediate task is to convert approximately 500,000 ounces from the existing resources into reserves, this will occur because of infill drilling and rebasing of the 2012 “top of market” costs used in the original project CAPEX and OPEX costs. Significantly, increasing the reserve base does not rely on new exploration success just development drilling of the existing resource. We believe the known mineralisation surrounding the Kulumadau pits, which currently contain about a third of the project reserves, will provide an excellent starting point from which to increase the reserve base of the entire project.”
Next steps
Geopacific’s focus is to maximise the development potential of Woodlark in the shortest possible timeframe.
Work undertaken to date is encouraging, highlighting substantial potential to increase reserves at all deposits. The advanced stage of this work includes a clear development plan to maximise resource conversion and achieve the 1.2 million ounce reserve target required to progress the earn-in agreement. Geopacific looks forward to the completion of the development plan and the announcement of the decision to proceed to Tranche 2 of the earn-in transaction before the end of 2016.
Development plan
Geopacific’s development plan will include clear milestones to improve economics and pit designs along with a drilling program to move existing Inferred Resources into the Measured and Indicated (M&I) categories with selective infill drilling.
Exploration potential
The exploration potential of Woodlark is being assessed simultaneous to the development plan . Scout drilling, geophysics and airborne magnetics have all successfully identified numerous targets that require follow-up exploration. These areas will be prioritised and developed as the project progresses.
Indications are that Woodlark has the potential to be a greater than five million ounce goldfield .
Potential to convert Inferred Resources to Indicated and Measured status
The drilling inventory at Woodlark is enormous for a junior company, with over 220,000 metres of RC and 45,000 metres of diamond drilling.
Drilling density in the areas of the current reserves is high, with drill hole spacing regularly as close as seven metres. This adds greatly to the confidence of the reserve estimation, particularly in high-grade areas.
In spite of its high density, drilling in the areas of the reserves account for less than half of the overall drilling at Woodlark. This has resulted in many areas being drilled only to Inferred status with wide spaced drill patterns.
Geopacific’s development plan will include a drilling program targeting the areas which Geopacific has identified as having the highest potential to be upgraded.

Potential to increase current resources
The majority of the Inferred resources are situated within and surrounding the original pits designs. This mineralisation remains open along strike and at depth in most cases.
Geopacific’s development plan will include selected drilling to increase resources surrounding the current reserves. Mineralisation has already been identified in these areas but the drill spacing was too wide to allow for its inclusion in the resource.
Potential to improve economics
The original DFS was undertaken in 2012, at the height of the mining boom. The high CAPEX and OPEX costs used in the DFS were commensurate with the environment at that time and resulted in the average cut-off grade for current resources being 1g/t ( Woodlark Island Gold Project Mineral Resources Increases, 31 July 2012 ).
The change in the global economic environment and mining industry cycle provides Geopacific with a clear opportunity to re-base the CAPEX and OPEX costs of the project.
Current permitting for Woodlark supports the development of a 1.8 million tonne per annum plant. Industry average in-pit cut-off grades appropriate for a plant of this scale are in the range of 0.5 to 0.6 grams/tonne.
Geopacific’s aims to achieve a cut-off grade within the standard industry range.
Potential at the Kulumadau Deposit
The first area of assessment for Woodlark is the resource conversion potential at the Kulumadau deposit.
The Kulumadau area currently covers two pits located on opposite sides of a circular geological structure. The mineralisation is derived from the same source at depth. Wide spaced drilling between the pits indicates the continuity of mineralisation and suggests that the current pits could be joined with infill drilling.
Open-cut pit shells were designed around the current M&I (red). Numerous zones of inferred mineralisation exist outside the current pit shells ( 4 million tonnes at 2.9g/t gold for 397,000 ounces of gold at 0.5g/t lower cut-off grade) making them readily amenable to conversion to M&I with infill drilling.
Resource conversion potential is demonstrated in Figure 1 below, where the resource is currently 910,000oz of gold at 0.5g/t lower cut ( Woodlark Island Gold Project Mineral Resources Increases, 31 July 2012 ). Original economics and pit designs allowed for only 282,000oz Au at 1.0g/t Au lower cut to be converted to reserves.
It is now clear that the Kulumadau mineralisation has formed within a ring structure created by an intrusive at depth. The Kulumadau West and Kulumadau East deposits are on opposite sides of this structure, with the Adelaide zone on the northern margin. It is evident that the mineralisation forms circular zones around the outside of the ring structure. The internal breccia zone is also clearly mineralised. The drillhole traces detailed below show the southern margin has only been lightly drilled and largely at the wrong orientation. From the current resource model below it is clear that there are numerous zones of gold mineralisation between the existing pits as well as high-grade extensions of the mineralisation below the pits. Potential to add to the resource also exists along strike from the known mineralisation (around the margins of the ring structure) where a low drilling density and non-optimal orientation means many zones have not not been effectively tested.

Figure 1: Resources at the Kulumadau area of the Woodlark Island Gold Project
Geopacific aims to undertake infill drilling, limited to selected areas, with a view to moving existing inferred resources into the measured and indicated categories. These areas will be selected according to Geopacific’s optimisation studies, which are being used to highlight the areas that hold the greatest potential to effectively upgrade inferred resources. These will be included in the development plan milestones.
Existing areas of measured and Indicated resources fall outside current pit designs, clearly demonstrated in Figure 2. Rebasing the OPEX costs will allow the pit shells to be redesigned with the aim being to capture an increased proportion of the measured and indicated resource and converting it into reserves.
The positioning of the M&I and Inferred resources in relation to the current pit designs can clearly be seen in the 3D model below.

Figure 2: Both M&I and inferred resource falls outside current pit shells
The resource model in Figure 3 shows high-grade gold zones with areas greater than 5 g/t gold (magenta) which fall outside the current pit designs (M&I and inferred). The majority of this mineralisation falls in the inferred category and remains open to depth. Infill drilling will allow some of these areas to be upgraded to M&I so that improved economics will allow them to be added to the reserve base.

The potential to increase the resource is demonstrated in the section (below) of the Kulumadau West pit in Figure 4. The in-pit ore zone extends to depth. A lack of drilling below the base of pit resulted in the the mineralisation being assigned to inferred status. Selected drilling has the potential to allow mineralisation such as this to be upgraded to M&I. Areas of the eastern and western margins of the current pits have not been drilled to determine whether other mineralisation is present.
