K92 Mining Inc. (“
K92” or the
“
Company”) (TSX-V
: KNT;
OTCQX
: KNTNF) is pleased to announce that it has
completed the processing of 4,256 tonnes of underground bulk sample
material and also extended underground development by an additional
114 metres along the Judd 1235 Level J1 Vein underground
development, within the +2.5km strike, sparsely explored Judd Vein
System at the Kainantu Gold Mine in Papua New Guinea.
The Judd 1235 Level J1 Vein underground
development has now been extended 114 metres since the length
disclosed in the Company’s September 3, 2020 press release, to a
total of 223 metres. As development advanced to the South, notably
higher grade material was encountered, with an estimated 6,600
tonnes at 13.57 g/t AuEq or 12.17 g/t Au, 0.79% Cu and 19 g/t Ag of
additional undiluted J1 Vein extracted and estimated from
underground channel sampling. Multiple high grade faces were
recorded from channel sampling, including: 5.46 m at 109.54 g/t
AuEq or 108.00 g/t gold, 0.27% copper and 100 g/t silver
representing our southernmost assay to date; 3.9 m thickness at
46.8 g/t AuEq or 43.3 g/t Au, 2.12% Cu and 29 g/t Ag, and; 4.4 m
thickness at 20.8 g/t AuEq or 15.1 g/t Au, 3.38% Cu and 57 g/t Ag.
Vein thickness averaged 3.7 metres and ranged from 2 to 6
metres.
The development drive has been designed as a
return airway (“RAD”) and as such has been developed with
dimensions of 5.5 m x 5.5 m, significantly larger than an ore drive
would be developed. Incorporating the resulting excess planned
dilution of over 50%, the extension mined an estimated 10,020
tonnes at 9.03 g/t AuEq or 8.06 g/t Au, 0.55% Cu and 9 g/t Ag.
Overall, the 223 metres of development has recorded continuous vein
mineralization along strike and the undiluted J1 Vein average
estimated vein grade is 9.65 g/t AuEq or 8.02 g/t Au, 0.95% Cu and
19 g/t Ag.
The bulk sample delivered a significant positive
grade reconciliation, returning a head grade of 6.50 g/t gold
equivalent or 5.19 g/t gold, 0.82% copper and 10.9 g/t silver,
compared to the projected average bulk sample diluted grade of 5.57
g/t gold equivalent or 4.4 g/t gold, 0.7% copper and 10.6 g/t
silver from underground development channel sampling. The treatment
of the bulk sample via flotation also delivered good recoveries of
88.8% for gold, 97.5% for copper and 88.2% for silver, similar to
recoveries at Kora. As the bulk sample was processed after the
recently commissioned Stage 2 Plant Expansion, the Company sees
potential for improvement in recoveries through operational and
flowsheet optimizations. Given the similar results achieved in
processing the Judd bulk sample, it is now being blended with Kora
material to optimize plant feed grades and characteristics.
A total of 229 tonnes of flotation concentrate
grading 86 g/t Au, 14.8% Cu and 178 g/t Ag was produced. The
concentrate meets specifications for K92’s existing offtake
agreement with no significant deleterious / penalty elements. It
is, however, intended to blend the Judd material with Kora for
treatment through the process plant, so a separate Judd concentrate
will not be produced.
The Judd bulk sample development was originally
intended as a ventilation infrastructure drive and therefore was
developed with large 5.5 m x 5.5 m underground development
dimensions. The drive dimensions are considerably greater than what
would have been utilized for production stoping, implying the
potential for grade improvement by reducing drive dimensions and
therefore mitigating planned external dilution. The bulk sample
represents a discrete portion of the Judd 1235 Level development
and does not include the high grade material reported in the most
recent face sampling that was mined after the processing of the
bulk sample.
(1) Gold
equivalent (AuEq) is calculated using
copper price of US$3.05/lb, silver price of US$16.05/oz and gold
price of US$1,400/oz.John Lewins, K92 Chief Executive
Officer and Director, stated, “The results from the ongoing
development along the Judd J1 Vein are extremely encouraging with
some very high grades being encountered as we develop to the south
including the most recent face sample reporting 5.46 metres at
109.54 g/t AuEq or 108.00 g/t gold, 0.27% copper and 100 g/t
silver.
In addition, as expected, the processing of the
Judd bulk sample has shown the material to be very similar
metallurgically to Kora, with similar recoveries, producing a good
grade concentrate with no significant deleterious elements.
Importantly the overall head grade of 6.50 g/t gold equivalent or
5.19 g/t gold, 0.82% copper and 10.9 g/t silver, was approximately
15% higher than the average diluted bulk sample drive grade of 5.57
g/t AuEq or 4.4 g/t gold, 0.7% copper and 10.6 g/t silver. Kora has
reasonably consistently delivered positive grade reconciliations
versus the resource model and underground grade control sampling,
and given the similar geology observed at Judd this is a
particularly encouraging initial result.
As we have only recently commissioned the
expansion to the process plant, we anticipate that we will be able
to improve Judd (and Kora) recoveries as we complete our
de-bottlenecking and optimization work which is currently under
way.
The results to date from the underground
development and the initial phase 1 underground drill program that
recently reported its first four drill holes, including 7.25 metres
at 256.09 g/t gold, 113 g/t silver and 0.42 % copper (258.01 g/t
gold equivalent, 5.30 metres true width) on the J1 vein (see the
Company’s November 9, 2020 press release), strongly highlights the
potential for Judd to represent a very significant additional
mining front for our Stage 3 Expansion. We therefore intend to
extend the initial underground drilling program and also commence a
surface drilling program of both Judd and Kora before year-end.
Underground development on Judd will also continue to be extended
to the South.”
