K92 Mining Inc. (“
K92” or the
“
Company”) (TSX-V
: KNT;
OTCQX
: KNTNF) is pleased to announce production in
the first quarter (“
Q1”) of 19,934 oz AuEq at its
Kainantu Gold Mine in Papua New Guinea.
During Q1, K92 produced 19,240 ounces of gold,
339,993 pounds of copper and 6,937 ounces of silver, or 19,934 AuEq
oz (based on a gold price of US$1,500/oz; silver price of
US$17.75/oz; copper price of US$2.70/lb). The quarter achieved
record mill throughput of 47,313 tonnes, mine material movements of
125,500 tonnes and development metres advanced of 1,560 metres as
Kainantu continues to benefit from the expanded mining fleet and
the completion of multiple infrastructure projects.
Mining operations in Q1 continued to focus on
Kora North and comprised of cut and fill stoping mining from the K1
vein at the 1170, 1205, 1225 and 1245 mRL levels as well as lower
grade K2 vein development tonnes from the 1170, 1200 and 1220 mRL
levels. The first long hole stope was brought into production on
the K1 vein during Q1 and significant development was focused on
opening up additional long hole stoping areas on K1 and K2. The
ramp up of mine production saw surface stockpiles increase to over
18,000 tonnes, equivalent to one-month plant throughput.
The blend of K1 and K2 material provided an
average head grade to the process plant for Q1 of 13.58 g/t Au and
0.36% Cu. Head grade was lower than previous quarters due to
greater focus on mining the K2 vein, with gold grades in-line with
budget and copper below budget.
The Kainantu mine continues to operate during
the Covid-19 pandemic, with a significant focus on health and
safety and risk-mitigation, as outlined in our March 23, 2020 press
release (K92 Announces Covid-19 Operational Update and Response
Plan). Importantly, K92’s financial position remains strong, with
approximately US$22 million of cash (as of December 31, 2019), the
vast majority of the Stage 2 Expansion capital spent, significant
concentrate receivables in transit to smelters and a stockpile of
over 18,000 tonnes at 11.5 g/t gold. The Company is making no
change to its production guidance at this time but will be
reviewing the situation as it develops in due course.
Financial details will be available in the
Company’s upcoming Q1 Financial Statements.

John Lewins, K92 Chief Executive Officer and
Director, stated, “We are very pleased with Kainantu’s significant
ramp-up momentum for the Stage 2 Expansion in Q1, including first
production from long hole stoping. The mine has performed well,
resulting in our stockpiles growing from a minimal amount to now
standing at ~1 month of production, or approximately 18,000 tonnes.
Importantly, development achieved record advance rates of ~1.6km in
Q1 consistent with the advance rates required in the long-term.
A key focus in Q1 was on further enhancing
Kainantu’s underground production capacity for the Stage 2
expansion with waste development and lower grade K2 vein
development to establish long hole stoping areas. Production
stoping from our first long hole stope commenced in late Q1. These
initiatives position Kainantu for a strong H2 as noted in our 2020
Operational Guidance.
And lastly, we would like to highlight that
Kainantu continues to operate in the Covid-19 pandemic environment.
While the environment is challenging and dynamic, the commitment of
our workforce has been extraordinary. As a result of their efforts,
we continue to strengthen our already solid financial position in
addition to having multiple near-term catalysts including our
updated resource, drilling results and PEA study on the next stage
of expansion in Q2.”
During Q1 2019, the Company announced the
commencement of the expansion of the Kainantu Gold Mine in Papua
New Guinea, with a goal of doubling current capacity to 400,000
tonnes per annum and increasing annual production to an average of
120,000 AuEq oz.
Based on the preliminary economic assessment
(“PEA”) published in January 2019, the major results from the
decision to expand production include:
- Total capital expenditure for 2019
is projected to be US$30 million, comprising US$12 million in
expansion capital, US$8 million in sustaining capital and US$10
million in capital development;
- Production is projected to be
68-75,000 oz AuEq in 2019 and is projected to be 115-125,000 oz
AuEq in 2020;
- Cash costs are expected to be
between US$580 and US$620 per oz AuEq, and all in sustaining costs
(“AISC”) are expected to be US$780 to US$820 per oz AuEq in 2019,
dropping to cash costs below US$500 per oz AuEq and AISC below
US$700 per oz AuEq in 2020;
- Number of employees is expected to
increase from the current 650 to 750 at the end of 2019, and to 800
by the end of 2020, with over 96% of all positions in-site being
filled by PNG Nationals;
- Based on the results of the
PEA:• Total production over the next 13 years would be 1.33
million oz gold and 130 million lbs copper;• Total revenue
for the period would be over US$2 billion;• Royalty payments
for the period would be US$50 million;• Tax paid to PNG
Government for the period, from payroll and corporate tax, would
total US$300 million;• Total sustaining capital of US$202
million would be required over the 13-year period; and• Net
cashflow would be US$1.03 billion, the net present value (“NPV5”)
would be US$710 million pre-tax, or US$559 million after tax, and
the internal rate of return (“IRR”) would be in excess of
350%.
The PEA is preliminary in nature and includes
inferred mineral resources that are considered too speculative
geologically to have the economic considerations applied to them
that would enable them to be categorized as mineral reserves, and
there is no certainty that the PEA will be realized. Mineral
Resources that are not Mineral Reserves do not have demonstrated
economic viability. The Company’s decision to expand production is
not based on a feasibility study of mineral reserves demonstrating
the economic and technical viability of the expansion. As a
result, there is increased uncertainty of the economic and
technical risks of failure associated with the decision.
K92 engaged H and S Consultants Pty Ltd to
complete a Mineral Resource Estimate for the Kora North Deposit
(Table 2). This resource together with the previously reported Kora
Mineral Resource Estimate dated March 2017 (Table 3) provide the
resource base for the updated PEA.
K92 engaged Mincore Pty Ltd (“Mincore”) to
complete the PEA for the expansion of the existing processing plant
to double its capacity to approximately 400,000 tonnes per annum.
The study found that the current crushing, milling and concentrate
handling circuits have sufficient capacity to treat the Kora mine
material at a rate of 400,000 tpa, subject to upgrading the
crushing and flotation circuits and plant services. The
estimated total cost of such expansion and upgrading would be
US$3.7 million, including EPC and commissioning with a contingency
of 10%.
The technical report containing the PEA, titled,
“Independent Technical Report, Mineral Resources Estimate Update
and Preliminary Economic Assessment of Kora North and Kora Gold
Deposits, Kainantu Project, Papua New Guinea” with an effective
date of September 30, 2018 (the “Technical Report”) was prepared by
Anthony Woodward BSc (Hons.), M.Sc., MAIG, Simon Tear BSc (Hons),
EurGeol, PGeo IGI, EurGeol, Christopher Desoe BE (Min)(Hons),
FAusIMM, RPEQ, MMICA, Lisa J. Park, BEng (Chem), GAICD, FAusIMM.
Refer to the Company’s news release dated January 8, 2018 for a
summary of the Technical Report and results of the PEA. The PEA
Technical Report can be found under the Company’s profile on
SEDAR.
The Company engaged Australian Mine and
Development Pty Ltd (“AMDAD”) to undertake the PEA mine plan for
Kora and Kora North, which involved:
- applying financial and processing
parameters to determine cut-off grades for stope design;
- generating three-dimensional stope
shapes and mining inventory using the CAE Mineable Shape Optimizer
(“MSO”) program;
- creating a conceptual development
layout to suit the MSO inventory;
- producing a project cash-flow
model; and
- producing a simple mining schedule
as input to the cashflow model.
The key results from the PEA for the combined
Kora North and Kora deposits are as follows:
- Could have a 13-year operating life
and treat 4.9 million tonnes @ 9.0 g/t Au, 20 g/t Ag & 1.3% Cu
(11.0 g/t Au Eq*);
- Could achieve an estimated pre-tax
NPV of US$710 million (US$559 million after-tax) using current
metal prices, exchange rate and a 5% discount rate;
- Initial capital cost estimated to
be US$13.6 million, including US$3.7 million for the plant upgrade
identified in the Mincore Scoping Study;
- The additional combined development
and sustaining capital cost is estimated at US$202 million spent
over the life of mine;
- Operating cost per tonne estimated
to be US$163/tonne for the first five years and US$153/tonne
thereafter;
- Cash cost estimated to be US$429/oz
Au Eq (inclusive of a 2.5% Net Smelter Return Royalty) and AISC of
US$615/oz Au Eq;
- Production of an estimated 135,000
Au oz and 2,100 Cu tonnes over a 5-year period from 2019 through to
2023, with average production of 90,000 Au oz and 6,500 Cu tonnes
for the balance of the life of mine; and
- Metal prices used were: Au -
US$1,300/oz; Ag – US$15/oz; Cu – US$2.90/lb.*AuEq used in PEA
calculated on above Current Metal Prices.
The Kora North resource estimate was defined
after just twelve months of underground exploration drilling.

The Mineral Resource estimate was prepared and
verified by Simon Tear (PGEO), consultant to the Company and a
director of independent consultancy of H & S Consultants Pty.
Ltd., Sydney, Australia (October 2018).
Key Assumptions and Parameters of Kora
and Kora North Resource Estimate
Mineralization comprises two parallel, steeply
west dipping, N-S striking quartz-sulphide vein systems, K1 &
K2, within an encompassing dilatant structural zone hosted by
phyllite. An additional structure, the Kora Link, has also
been defined and provides a possible link between the two main vein
systems.
Underground drilling consists of diamond core
for a range of core sizes depending on length of hole and expected
ground conditions. Sampling is sawn half core under
geological control and generally ranges between 0.5m and 1m.
Underground face sampling is completed for every fired round and is
to industry standard.
QAQC data indicated no significant issues with
the accuracy of the on-site analysis.
Core recovery of the mineral zone was initially
90%, this has improved to >95%. There is no relationship
between core recovery and gold grade. Geological logging is
consistent and is based on a full set of logging codes covering
lithology, alteration and mineralization.
The geological interpretation of the vein
systems is represented as 3D wireframe solids snapped to a
combination of diamond drillhole data and underground face
sampling. Definition of the wireframes is based on identified
gold mineralisation in drillcore nominally at a 0.2g/t Au cut off
in conjunction with geological control/sense and current mining
widths.
Gold Equivalent (AuEq) g/t was calculated using
the formula Au g/t +(Cu% x 1.53) + Ag g/t x 0.0127. (No account of
metal recoveries through the plant have been used in calculating
the metal equivalent grade. However, production is currently
achieving 93% metal recovery for both gold and copper and gold is
currently providing 95% and copper 5% of the total revenue of the
mine).
Gold price US$1,300/oz; Silver US$16.5/oz;
Copper US$2.90/lb.
The mineral resource estimate for the Kora
deposit is based on the technical report prepared in accordance
with National Instrument 43-101 – Standards of Disclosure for
Mineral Projects (“NI 43-101”), and titled, “Mineral Resource
Update and Preliminary Economic Assessment of Irumafimpa and Kora
Gold Deposits, Kainantu Project, Papua New Guinea," with an
effective date of March 2, 2017. This provides additional
information on the geology of the deposits, drilling and sampling
procedures, lab analysis, and quality assurance/quality control for
the project, and additional details on the resource estimates.
Mineral Resources that are not Mineral Reserves do not have
demonstrated economic viability.
