K92 Mining Inc. (“
K92” or the
“
Company”) (TSX-V
: KNT;
OTCQX
: KNTNF) is pleased to announce production in
the third quarter (“
Q3”), of
22,261 oz AuEq at its Kainantu Gold Mine in Papua New Guinea.
During Q3, K92 produced 21,298 ounces of gold,
488,020 pounds of copper and 7,127 ounces of silver, or 22,261 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 also achieved
record mill throughput of 64,702 tonnes following successful
commissioning of the Stage 2 process plant expansion to double
throughput from 200,000 tpa (~550tpd) to 400,000 tpa (~1,100 tpd),
including 5 consecutive days significantly above design, averaging
almost 1,200 tpd.
Mining operations in Q3 focused on Kora’s K1 and
K2 veins and comprised development tonnes on the K1 vein on five
levels, K1 vein long hole stoping (modified AVOCA method) on the
1205 and 1225 mRL level, K2 vein development tonnes from the 1170
mRL level and K2 vein long hole stoping (modified AVOCA method) on
the 1185 mRL level. Importantly, Q3 marked the second full quarter
of long hole stoping, which commenced in March 2020 on the K1 vein.
To date, long hole stoping has performed to design on both the K1
and K2 veins and has provided a notable positive impact on
operational flexibility, including multiple consecutive days
exceeding 1,100 tpd of plant feed from underground in Q3. Long hole
stoping is planned to increase through 2020 and K92 remains on
track to consistently achieve throughput of 1,100 tpd of plant feed
from underground by year end.
The blend of K1 and K2 material provided an
average head grade to the process plant for Q3 of 11.29 g/t Au and
0.38% Cu. Plant feed grades were deliberately lowered during the
commissioning period to minimize the potential for gold losses.
Gold head grades continued to deliver a positive grade
reconciliation. Grades are expected to increase in Q4 as
higher-grade mining areas are reprioritized.
In Q3, underground infrastructure development
encountered significant mineralization in the Judd #1 Vein (“J1
vein”), one of four known veins in the Judd vein system. As a
result, the infrastructure drive was modified to develop along the
J1 vein, providing a bulk sample to be treated during Q4. In
addition, a drilling program has commenced on Judd (see September
3, 2020 press release – K92 Mining Announces Bulk Sample
Preliminary Results at Judd Vein System and Commencement of Phase 1
Judd Drill Program). There are currently two drill rigs targeting
Judd from underground, and the underground development drive
continues to be advanced to the South. Judd is located on the
mining lease and runs parallel to and approximately 200 metres to
the North East of Kora. A portion of the Judd material mined has
already been processed and blended with Kora material.
The twin incline project made considerable
progress in Q3, including completing surface ground support, two
portals and portal ground support steel sets. Development has also
now advanced through weathered ground into competent fresh rock.
See Fig 1 for a photo of the Twin Inclines.
The Kainantu mine continues to operate during
the COVID-19 pandemic, with a significant focus on health and
safety and risk-mitigation. On March 20, 2020 the Government of
Papua New Guinea declared a COVID-19 State of Emergency (“SOE”)
(see March 23, 2020 press release - K92 Announces COVID-19
Operational Update and Response Plan) and on June 16, 2020 the
Government of Papua New Guinea lifted the SOE (see June 16, 2020
press release - K92 Mining Inc. Provides Operations and Stage 2
Expansion Update After Lifting of PNG COVID-19 State of Emergency),
resulting in a further easing of restrictions. After the lifting of
the SOE, Kainantu has experienced a significant improvement in the
movement of personnel, with exploration and development projects
resuming.

John Lewins, K92 Chief Executive Officer and
Director, stated, “We are extremely pleased to have successfully
completed the commissioning of our Stage 2 Plant Expansion, which
represents an important milestone for the Company and a positive
step-change in our throughput capabilities, doubling from 200,000
tpa (~550 tpd) to 400,000 tpa (~1,100 tpd). The performance of the
expanded plant to date has exceeded expectations on throughput,
with the plant achieving 5 consecutive days significantly above
design, averaging almost 1,200 tpd. Recoveries have also been solid
post-commissioning and have been steadily increasing through late
Q3 and into Q4 as our team fine-tunes the circuit.
Mining operations have also been tracking well,
benefiting from an expanded fleet and a significant boost to
operational flexibility, with long hole stoping now firmly
established on the K1 and K2 veins. During Q3, multiple consecutive
daily records were achieved, with underground plant feed material
movements exceeding 1,100 tpd and a solid quarter-end stockpile of
~18,000 tonnes. Kainantu remains on track to meet its goal of
consistently achieving 1,100 tpd of plant feed from underground by
year-end.
We are especially excited about the remainder of
this year for Kainantu. The fourth quarter is expected to deliver
our strongest quarterly production to date, benefitting from the
completion of the Stage 2 Plant Expansion in Q3. Exploration
activities are also ramping up considerably, with nine drill rigs
now on site, and one more rig expected to arrive by end of year.
Drill rigs are currently targeting the Judd, Karempe and Kora vein
systems, with exploration on Kora South planned to commence this
quarter. The second drill program is also scheduled to commence at
Blue Lake this quarter. We expect to provide exploration updates on
our vein field exploration programs near-term.
I would like to, once again, highlight the
exceptional commitment of our workforce and the quality of the Kora
Deposit. Despite the challenges of the COVID-19 pandemic, we
continue to take significant steps forward towards increasing
production and exploration activities, while also strengthening our
financial position. The support of all levels of Government in
Papua New Guinea, especially during the COVID-19 pandemic, has also
been a major positive factor in all of our achievements to
date.”
