The recently completed Resource definition drilling campaign at Misima (see ASX release 30[th] of March 2020) was designed to define potential shallow starter pit mineralisation to provide mill feed in the early stages of the proposed Misima mining operation. Starter-pit ore offers the opportunity to generate early cash-flow for Kingston while it establishes access to the larger-scale 2.6Moz Umuna Resource.
The diamond drill holes reported in this announcement were situated within the existing 220koz Ewatinona Inferred Mineral Resource area (see Figure 1), with drilling designed to confirm existing mineralisation and test the revised structural interpretation as well as potential depth extension. It is anticipated that the results from the drilling program will provide increased confidence in Resource modelling, while also highlighting the potential for additional ounces given the limited density of historical drilling.
A recent structural study of historical data and pit mapping has also delineated two main trends of mineralisation at the existing Ewatinona pit (see Figure 1). Grade distribution in 3D blast hole datasets supports the mineralisation model of gold-rich quartz-carbonate-base metal sulphide breccias and veining within ESE and NW-to-NNW trending structures with crackle breccia haloes.
A 0.2g/t Au to 0.4g/t Au mineralisation envelope broadly mirrors the NNW and ESE orientations (Figure 2). Higher-grade 1.0g/t Au mineralisation envelope trends predominantly ESE with the highest grade (>2.5g/t Au) mineralisation occurring within local zones of greater dilation and steep-plunging shoots and at the intersection of these two structural trends (Figure 3).

The Resource definition drilling has focused on in-filling mineralisation below the Ewatinona open pit and extensions of the modelled mineralisation trends to depth and to the ESE. The remaining Phase 2 diamond drill holes lie along strike to the east and north-west and down-dip below the Ewatinona pit. Assays are pending for several holes testing the potential eastern extension of the Ewatinona Resource.
Results from this drilling will be incorporated into the pending Resource update, which is expected to be delivered in the June 2020 Quarter.
In addition to the potential to expand the current Resource, the Resource update will also be focused on converting the existing 220koz Ewatinona Inferred Resource to the higher-confidence Measured and Indicated categories, making it available for conversion to Ore Reserves following the completion of a PreFeasibility Study (PFS) for the Misima mining operation.
==> picture [131 x 37] intentionally omitted <==
Kingston also anticipates an opportunity to review the underlying gold price assumption of US$1200/oz which was used to inform the “reasonable prospects for eventual economic extraction” requirement for the estimation of the existing 2.6Moz Umuna Resource.
Kingston Resources Limited Managing Director, Andrew Corbett, said: “ Resource definition drilling at Ewatinona continues to deliver excellent drilling results that are expected to have a positive impact on the impending Resource update.
“As announced on 30 March 2020, the Resource definition program within the Quartz Mountain area is now complete, with a number of final assays still awaited. These will all be incorporated into the broader Misima Mineral Resource update due in the June Quarter.
“The Company has made excellent progress with its development strategy over the last six months, identifying and drill-testing a number of potential starter pit targets. Ewatinona is now clearly emerging as an ideal opportunity for a starter pit, with an existing 220koz Resource, strong potential for growth, and proximity to infrastructure. The impending Resource update will help us to validate this concept ahead of the transition to mining studies over the balance of 2020.”

Results from Phase 2 Resource definition drilling received to date indicates the drilling has intersected veins and structures characteristic of the ore historically mined at Ewatinona. Commonly, mineralised intervals contain a higher grade core within the broader mineralised zone. These intercepts confirm the geometry and location of interpreted moderate to steep-dipping structures and mineralised zones within the Mineral Resource.
Gold mineralisation at Ewatinona occurs within carbonate base metal style mineralisation assemblages as veins and breccias and infill within micro diorite that has been pervasively altered by silica, sericite, clay and pyrite. Typically, gold intervals coincide with zones that host sphalerite, galena, pyrite and silica mineralisation. Geological logging and orientated veins and breccias in drill core reflect the broader-scale interpretation of mineralisation hosted by a series of moderate to steep-dipping, stacked structures with WNW to NW trends.
Next Steps
The Resource definition drilling program has been completed and work on the Resource update is underway. External consultants have been engaged to assist with the technical work related to producing the new Mineral Resource.

About Kingston Resources
Kingston Resources is a metals exploration company which is focused on exploring and developing the worldclass Misima Gold Project in PNG. Misima hosts a JORC resource of 2.8Moz Au. Misima was operated as a profitable open pit mine by Placer Pacific between 1989 and 2001, producing over 3.7Moz before it was closed when the gold price was below US$300/oz. The Misima Project offers outstanding potential for additional resource growth through exploration success targeting extensions and additions to the current 2.8Moz Resource base. Kingston currently owns 77% of the Misima Gold Project where active exploration programs are underway.
In addition, Kingston owns 75% of the high-grade Livingstone Gold Project in Western Australia where active exploration programs are also in progress.

|---|---|---|
| Mineral | • | Misima Island is part of the Louisiade Archipelago within Milne Bay Province of PNG. It is situated in the |
| tenement and | Solomon Sea about 625 km east of Port Moresby, the capital of PNG. The site is located at an approximate | |
| land tenure | latitude of 10° 40’ South and longitude of 152° 47’ E. | |
| status | • | The Property consists of a single Exploration Licence, (EL) 1747, comprising 53 sub blocks, covering a |
| total area of 180 km2. This EL is valid until 20 March 2021. All conditions pertaining to compliance of the | ||
| title have been met. The Property is located on the eastern portion of the island and includes the historic | ||
| mining areas of Umuna and Quartz Mountain. There are no known impediments. KSN holds title via its | ||
| subsidiary Gallipoli Exploration Ltd. Gallipoli is the legal entity and tenement holder and is responsible for | ||
| performingits obligations under the_Mining Act_1992. | ||
| Exploration | • | The project area has been subject to mineral exploration by a number of previous parties, most notably |
| done by other | Placer Pacific between 1987 to 2004. | |
| parties | • | For a detailed summary of previous explorers’ work readers are recommended to read the JORC Table 1 |
| released with the November 2017 Misima resource update(ASX:KSN announcement 27 November 2017). | ||
| Geology | • | Misima Island forms part of the Louisiade Archipelago which is a continuation of the Papuan Fold Belt of |
| the Papuan Peninsula offshore eastwards through the Papuan Plateau. The oldest rocks on Misima are | ||
| Cretaceous to Paleogene metamorphic rocks, which can be subdivided into the western Awaibi Association | ||
| and the younger overthrust eastern Sisa Association that is host to the gold and copper mineralization. The | ||
| two associations are separated by an original thrust fault with later extensional activation. | ||
| • | Mineralisation deposit style on Misima Island is best described as Intermediate Sulphidation Epithermal | |
| due to the strong association with porphyry Cu Au style alteration, veining and characteristics, the | ||
| dominance of Ag Zn Pb Au Cu Mn geochemistry as well as complex alteration styles and geometry. | ||
| • | Styles of mineralisation observed include multiphase hydrothermal breccia, stockworks both sheeted and | |
| three-dimensional, skarn, jasperoidal replacement, and poorly banded vein infill of quartz and carbonate | ||
| with associated pyrite, galena, sphalerite, barite and minor tetrahedrite. | ||
| • | Structurally the Umuna geometry is typical of a complex fault array with a large major fault hosting the | |
| majority of the precious metal mineralisation with numerous ancillary splays developed in the footwall to | ||
| the main structure. The intersection of the splays and the dominant Umuna Fault are loci for zones of well- | ||
| developed mineralisation. Mineralisation has a dominant structural control however strong secondary | ||
| stratigraphic controls are also observed in particular where skarn style mineralisation is developed in Halibu | ||
| Limestone – Ara Schist contacts. A series of north west trending splays intersect and control the loci of the | ||
| higher-grade material within the Umuna fault zone. | ||
| Drill hole | • | Hole locations and orientations are displayed in the table within the body of the announcement. |
| Information | ||
| Data | • | Where significant intersection results are used, the average grades are weighted by the sample width of |
| aggregation | each assay within the intersection. | |
| methods | • | No metal equivalence calculations are used in reporting. |
| Relationship | • | Drill orientation is as close to perpendicular as possible given the limitations of the rig used. True widths |
| between | vary from approximately 85% to approximately 100% of the down-hole width based on the current |
