Management Comments
According to Andrew Corbett, the Managing Director of Kingston, the release of the LOM plan signifies the
beginning of a new phase of growth for Mineral Hill and propels Kingston into the enviable position of a
copper and gold producer in an outstanding jurisdiction.
“The Kingston team has been working hard to deliver the updated LOM plan, which includes metallurgical
studies, geological modelling, engineering optimisation and design, as well as thorough cost estimation and
minimisation. This comprehensive technical work will ensure a successful transition back to conventional
mining and establish the foundation for long-term growth.
We view the current Tailings Project results as evidence of our ability to evolve from an explorer/developer
to a profitable gold producer. This represents Phase 1 of our Mineral Hill story.
The LOM plan now marks Phase Two of our long-term plans at Mineral Hill. Our team has finalised the
initial Mineral Resource and Ore Reserve inventory, and we know there is huge extension potential within the
Mining Lease alone. Additionally, we have identified priority exploration targets across our two adjoining
exploration leases, and we have a pipeline of resource development targets that could feed our processing
plant well beyond the LOM inventory.
We are confident that we can further demonstrate our expertise in open pit and underground mining, and
explore opportunities to expand our mining inventory through organic means or acquisitions in the region.
This would bring us into Phase Three, where we will focus on increasing the processing plant’s capacity and
sourcing additional high-grade gold and copper dominant ore.
The fully approved mine with abundant infrastructure at Mineral Hill was a key attraction for Kingston when
the project was acquired in January 2022. The significant plant and equipment located within the processing
plant enables us to rapidly increase cashflow from operations and maximise utilisation across our assets. Our
comprehensive permits and approvals provide us with a regulatory advantage, enabling us to transition
immediately from the Tailings Project to hard rock mining.
We are hugely excited to be taking this next step in scaling our operations. With the launch of the Placement
and SPP, alongside existing cash and debt facilities, we will now have the funds to progress Kingston’s growth
plans in earnest. The Company is very pleased with the level of support from our existing shareholders and
we are also pleased to welcome several new quality institutional investors to the Kingston register through
their participation in the Placement transaction. We remain committed to working closely with Lachlan Shire,
the Wiradjuri People, and our local community in Condobolin to identify opportunities for mutual growth and
to increase prosperity and well-being across the region.”

Cautionary Statement
The Scoping Study referred to in this announcement has been undertaken for the purpose of re-establishing
open pit and underground mining at Mineral Hill. It is a preliminary technical and economic study of the
potential viability of the project. The LOM plan includes Probable Ore Reserves from the Tailings Project and
the Pearse open pits, as well as Mineral Resource Estimates for the Southern Ore Zone (SOZ) and Jack’s Hut
to estimate the production target. All Ore Reserves and Mineral Resources underpinning this LOM plan have
been prepared by Competent Persons in accordance with the 2012 JORC reporting guidelines.
The production target is based on low level technical and economic assessments that are not sufficient to
support the estimation of ore reserves. Further exploration drilling, evaluation work and appropriate studies
are required to estimate ore reserves and refine the economic forecasts. The Scoping Study is based on the
material assumptions outlined in this announcement. While Kingston considers all the material assumptions
to be based on reasonable grounds, there is no certainty that they will prove to be correct or that the range of
outcomes indicated by the Scoping Study will be achieved.
The Company advises that the Probable Ore Reserve provides 48% of the LOM processing plant feed tonnage.
The underground production target is based on Mineral Resource Estimates which are classified as Measured,
Indicated and Inferred Resource and comprise 3%, 16% and 34% of the LOM plan respectively. There is a
low level of confidence associated with Inferred Mineral Resources and there is no certainty that further
exploration work will result in the determination of Indicated Mineral Resources or that the production target
itself will be realised. The planned mining and processing up to the end of CY24 is comprised of 96% Probable
Ore Reserves and 4% remaining Measured, Indicated and Inferred Mineral Resources.
The stated production target is based on the Company’s current expectations of future results or events and
should not be solely relied upon by investors when making investment decisions. Further evaluation work and
appropriate studies are required to establish sufficient confidence that this target will be met.
The Company notes that the Project forecasts a positive financial performance and is therefore satisfied that
the use of Inferred Resources in production target reporting and forecast financial information is not the
determining factor in overall Project viability and that it is reasonable to report the LOM plan with Inferred
Resources.
Mineral Hill has all major infrastructure in place to execute the mine plan and only minor refurbishment is
required to reinstate the comminution circuit and floatation circuits. The cash flow from the Ore Reserve
inventory at the front end of the schedule is the main driver of the project payback of 16 months. Underground
drilling is planned for the December quarter 2023, which will test the Inferred portions of the production target.
This will allow for an updated MRE and an initial Ore Reserve in the June quarter of 2024. The infrastructure
and operational layout at Mineral Hill are highly scalable, meaning the inclusion or exclusion of Inferred
material does not influence Kingston’s decision to make a financial commitment to the project.
The Company has concluded that it is has a reasonable basis for providing the forward-looking statements
included in this announcement. The detailed reasons for that conclusion are outlined throughout this
announcement. See section titled Important Notices for additional information.

Metal Equivalents
This announcement quotes metal equivalent grades for the life of mine plan, Mineral Resources and Ore
Reserves. Price assumptions used are based primarily on consensus forecasts with adjustments based on
company expectations. Gold equivalent (AuEq) conversion factors are used within the announcement and are
calculated by dividing price/unit for each commodity (Cu/t, Au/oz, Ag/oz, Pb/t, Zn/t) and multiplying by the
metallurgical recovery. Copper, lead and zinc grades also use a lb/tonne multiplied by grams/oz conversion.
Since the metallurgical recovery varies according to deposit type, the metal equivalent factors are unique for
each deposit (namely, Tailings Project, open pit and underground).
AuEq g/t = (Cu CAu * Cu %) + (Au CAu * Au g/t) + (Ag CAu * Ag g/t) + (Pb CAu * Pb %) + (Zn CAu * Zn %)
Metallurgical recoveries are based on historical production (2010-2016) as well as recent metallurgical test
work and are applied to the Resource and Reserve calculated grades for each commodity. The Company is of
the opinion that all the elements included in the metal equivalent calculations have a demonstrated potential
to be recovered and sold. Mineral Hill will have a CIL circuit, Cu flotation circuit, Pb flotation circuit and Zn
flotation circuit to produce three different concentrates as well as gold dore.

Overview
Kingston’s Life of Mine (LOM) plan for Mineral Hill forecasts production out to middle of 2027. The forecast
includes a 69% increase in payable metal output between FY23 and FY25 from 17koz AuEq to 29koz AuEq.
The company will transition from gold and silver dore production today, adding gold concentrate within CY24
and then adding separate copper, lead and zinc concentrates by the end of CY24. A key strength in the mine
plan is the large proportion of gold production over the LOM, complemented with copper and base metal
credits.
Figure 1 shows the ramp up of payable metal for all projects at Mineral Hill up to FY25. Forecast mined grade
increases to 3.3g/t AuEq in FY25 with the commencement of underground mining. The polymetallic nature
of the underground production target contributes to a high LOM grade of 3.3g/t AuEq (grades in recovered
terms). All-in-sustaining costs2 average A$1,368/oz over the LOM.

The mining sequence will commence with the continuation of the Tailings Project, which has been reconciling
positively to the original Resource & Reserve estimates and providing an average free cash flow of over $1.5m
per month this calendar year to date. Ore Reserves within the two open pits will be mined over a period of 13
months, commencing in December this year. Access to the existing underground development will begin this
year to allow for infill and extensional diamond drilling. Underground development will commence in October
2024, however there is already substantial development proximal to the planned stopes, so there is potential
to deliver material cash flow early in the underground mining phase.
2 All-in-sustaining cost (AISC) includes mining, processing, site general & administration, realisation, royalties and
sustaining capital costs.
3 FY23 forecast includes actual results to the end of April 2023 and forecasts to 30 June 2023.

Mining
Tailings Project
Kingston acquired Mineral Hill Mine as an operating asset on 18 January 2022, with the Tailings Project
already being commissioned. The performance of the project has been dramatically improved by the
Company, with processing recoveries increasing from 40% in February 2022 to 65.8% in April 2023.
Increasing the mining rate and optimising feed density have been key factors in lifting gold production and
recovery.
The Tailings Project has been a demonstrable technical and financial success for Kingston. The Company
reported A$1.3m of net profit for the half year period ending 31 December 2022. May 2023 production results
demonstrated that gold production remains strong at 1,827 oz produced and cost management has kept all-insustaining costs at A$1,312/oz. Importantly, the unhedged position allowed for an average gold price of
A$2,999/oz during May and this is making a substantial contribution to the company’s cash balance, which
was approximately A$11.5m as of 31 May 2023.

Open Pit Mining
The Pearse deposits are comprised of two separate ore bodies located 1km northwest of the Mineral Hill
processing plant site. The mining schedule for open pit mining is based on the Pearse Ore Reserves 8. Pearse
South will be a cut back and deepening of the existing pit and Pearse North will be a new pit. All permits and
approvals are in place to commence mining in December 2023. Historical mining at Pearse South totalled
219kt at 6.06g/t Au and 64g/t Ag.
Pit optimisation and design parameters used to build the mine plan are shown in Table 4. The high-grade
nature of the ore is a key factor driving the profitability of the pits. Details on the assumptions and unit rates
for the open pit reserve were released to the market on 15 March 2023. The open pit mining physicals are
shown in Table 5.

Underground Mining
The existing underground infrastructure is a major advantage for recommencing underground production at
Mineral Hill. Capital development is minimised over the LOM because of the site’s mining history and the
location of existing declines adjacent to planned stope production.
The underground mining plan commences with an initial phase of refurbishment and capital works. This
involves reinstating the underground development, communication & electrical upgrades, safety installations
and water pumping. Table 6 lists out the required work and associated capital expenditure.

The Underground production target is based on the Southern Ore Zone (SOZ) and Jack’s Hut Mineral
Resource Estimates (MRE) (see ASX announcements on 11 November 2022 and 21 March 2023). The mining
method will consist of long hole stoping with partial rock back fill.
Underground Stope Optimisation
The Mineable Shape Optimiser (MSO) program in Datamine™ Studio UG was used to generate mineable
stoping shapes. The evaluation was driven by a net value per tonne (NVPT) field in the block model, calculated
using the process recoveries and costs, site fixed costs, product pricing and royalties. Fixed and variable
mining costs were estimated based on supplied contractor budget prices with adjustments made for owner
mining. Stoping and development costs were then estimated by applying fixed and variable costs to the mining
physicals. Average stoping and development cost assumptions used in Kingston’s financial analysis were
assumed to be $70/t for stoping and $6000/m for development.
The processing flow sheet assumes sequential flotation of copper, then lead, then zinc, followed by a CIL tail
treatment. Process and site fixed costs are based on the operation’s production history with adjustments for
current labour, power and reagent costs. Processing recoveries by metal, concentrate stream and lode were
used for the optimisation. The full list of parameters used to derive the initial optimised stope shapes and the
subsequent Financial Model is shown in Table 7.

Transitioning to open pit and underground ore feed will require refurbishment of the comminution and
flotation circuit. The initial open pit phase will produce gold concentrate and dore. The processing of the
underground ore will produce separate copper, lead and zinc concentrates. Treatment of the flotation tail
through the CIL will also occur to extract the remaining precious metals. Figure 8 shows the detailed process
flow sheets for open pit and underground ore types.
All major processing infrastructure and facilities exist to execute Kingston’s updated LOM plan. Feasibility
study level cost estimation and scheduling for the processing plant refurbishment was completed by Maxwell
Energy and Resources and the key capital cost estimates are listed in Table 11.

Mine Scheduling
The key phases in transitioning to open pit and underground mining are shown in Figure 9. Cash flow from
the Tailings Project will continue alongside underground re-entry works, processing plant refurbishment and
open pit waste stripping. Processing of open pit oxide and sulphide ore is due to commence in Q2 CY24.
Processing of underground production target inventory will commence at the end of CY24. Figure 9 shows
the full LOM mining schedule.
Figure 9: Gannt chart of the transition to conventional open pit and underground mining.
The flotation plant is scheduled to operate at a 380ktpa processing rate (above the 350ktpa nameplate),
equating to an average of 32kt per month. The Company plans to maximise the plant’s utilization and then
investigate ways to increase capacity. Mineral Resources within the Mining Lease amount to 8.9Mt, drilling
and exploration focussed on increasing confidence on the Inferred portions, resource extensions and new
discoveries. The LOM mining inventory comprises 96% Ore Reserves to the end of CY24. Planned
underground drilling aims to increase the confidence of Inferred Mineral Resources and potentially expand
the Ore Reserves.
Mining higher grades in the open pits and underground is one of the main drivers in the substantial increase
in payable metal output over the next three years. Payable metal is forecast to increase 69% between FY23
and FY25 based on the company’s LOM projections (see Figure 12).

Infrastructure
Existing infrastructure on site includes a CIL circuit, floatation circuit, power and water supply, waste rock
dump, haul roads, tailings storage facility, offices, workshop and site access. Accommodation for employees
is based in Condobolin.
All concentrate produced will be bulk shipped in containers utilising the same route that was used previously
for the transport and sale of base metal concentrates from site. Shipping containers will be trucked
approximately 135km to the Narromine rail head via the public road network for aggregation into suitable
train loads for onforwarding to Port Botany. Sea containers will then be loaded onto cargo ships for export to
overseas markets.
Kingston Resources has a targeted long-term employment plan for the mine and is committed to local training
and employment at the Project. The emphasis will be on recruiting from the local shire and building mining
skillsets to sustain a long-term operation for the region.
Approvals and ESG
Kingston’s LOM plan is within approved mining licences and the company has officers qualified for fulfilling
all the statutory requirements. The list and status of mining tenure is included in the Appendix.
The site has an EPA license that covers all current and proposed activities, methods and reagents. EPL3151
allows for the processing of 700ktpa. There is a bore license in place for the dewatering of the underground
workings and this covers all site water requirements up to 630ML pa (80BL242753) with current extraction
in the order of 230ML pa. The site has a Rehabilitation Management Plan and the associated rehabilitation
bond, cash backed, is in place to cover all currently approved mining and processing activities. There are no
impediments to the LOM plan from native title or local landholder access.

Product Marketing
The LOM plan forecasts sale of gold dore, gold concentrate and three separate concentrates for copper, lead
and zinc. Kingston is currently selling gold dore to ABC Refinery in Sydney. Based on current discussions
with metal traders, gold concentrates can be sold with as low as 15 g/t Au. All concentrate from the two Pearse
pits is expected to be above 30 g/t Au and should be readily saleable. Base metal concentrates were sold from
Mineral Hill when the mine was previously in production. Discussions are underway with concentrate
marketing agents and there is indication of strong demand for all concentrates.
Project Economics
Revenue
Copper and gold sales collectively make up 74% of forecast revenue over the LOM (see Table 13). As the site
transitions into polymetallic ore from the underground mine, revenue from base metals becomes more material.
The Company is excited about the potential of increasing mineral inventory in this part of the deposit and the
possibility of moving this forward in the schedule.
