NEWS RELEASE
May 16, 2017 Vancouver, British Columbia
K92 is pleased to provide a production update on the Kainantu Gold Mine for the March
Quarter of 2017.
Total production of 23,400 tonnes mined, primarily from development of the 1205
mRL, 1220 mRL and 1235 mRL, a production rate significantly above the 13,645
tonnes scheduled in the AMDAD Mine Plan
The first stope production now mined from the remnant stopes
The Process Plant treated just under 12,000 tonnes in March and has regularly
achieved over 600 tonnes per day, which is above design throughput
Grade control drilling and sampling for the initial mining area, comprising stopes
and development from 1205 mRL to 1265 mRL levels and between 59450 North and
59700 North, defines 38% more tonnes and 13% more ozs than the AMDAD design
Detailed design work incorporating all res ults from the grade control drilling and
face samples has defined a total of 35,716 tonnes at a gr ade of 6.53 g/t Au (25,446
tonnes @ 6.20g/t Au Measured Resource and 10,260 tonnes @ 7.35 g/t Indicated
Resource) as remaining to be mined from initial stopes and 1,175 tonnes at a grade
of 7.52 g/t Au (Indicated Resource) to be mined from the 1250 mRL level (see Table
3).
As at 31 st March 2017, surface stockpiles, from mining of development material,
contained a total of 9,000 tonnes at a gr ade of 4.54 g/t Au. This material was
classified as a Measured Resource.
Over 270 tonnes of concentrate trucked to th e port of Lae during the quarter with
shipments ongoing
Mining
The current mine plan is based upon the 3 Year Mine Plan prepared by Au stralian Mine Design
and Development (“AMDAD”) which is detailed in the “Independent Technical Report, Mineral
Resource Update and Preliminary Economic Assessment (“PEA”) of Irumafimpa and Kora Gold
Deposits, Kainantu Project, Papua New Guinea” with an effective date of March 2, 2017 (the
“Technical Report”). Formal approval to restart underground production was received from the
Mineral Resources Authority (“MRA”) in late October 2016 following the successful
rehabilitation and refurbishment of the undergr ound mine, so the effective start date for the
AMDAD Mine Plan has been taken as 1st November 2016.
The majority of mining production to date has come from development on the 1205 mRL, 1220
mRL and 1235 mRL production levels betwee n 59450 North and 59700 North, with a small
amount of approximately 1,000 tonnes recovered from remnant stopes left behind by the
previous operators on the 1250 mRL level.
The AMDAD Mine Plan based on the current Iruma fimpa Resource provided in Table 4 below,
called for a total of 13,645 tonnes at a grade of 6.69 g/t of development material containing 2,935
ozs to be mined during the quarter, with no st ope production due until month 7. This material
would be part of the Inferred Resource. In comparison K92 has mined 23,400 tonnes containing
3,400 ozs, with approximately 1,000 tonnes comi ng from existing remnant stopes based on
material processed or remaining in stockpiles. (See Table 1).
The major difference between the AMDAD Mine Plan and actual performance to date is that a
significant tonnage of material outside of defined stoping areas was originally classified as waste
within the AMDAD plan but wa s processed as lower grade material during the commissioning,
rather than being waste.
As was disclosed in the Company’s news re leases dated March 3, 2017 February 4, 2016, the
Company’s decision regarding production at th e Kaintantu Gold Mine was not based on a
feasibility study demonstrating economic and tec hnical viability and, as a result, there is
increased uncertainty and multiple technical and economic risks that are associated with this
decision. These risks include areas that are analyzed in detail in a feasibility study, such as
applying economic analysis to resources and reserves, more detailed metallurgy, and a number of
specialized studies in areas such as mining and recovery methods and environmental and
community impacts. In addition, th ere are certain specific risks associated with the Kaintantu
Gold Mine (as described in the Technical Report) including, but not limited to, inadequate water
access and access to power. Project failure may adversely impact K92 and future profitability. As
such, K92 cautions the reader that where projects are put into production without first
establishing mineral reserves, as opposed to mineral resources, supported by a te chnical report
and completing a feasibility study such projects ha ve historically had a higher risk of economic
or technical failure.
The preliminary economic assessment (the “PEA ”) contained in the Technical Report is
preliminary in nature and includ es inferred mineral resources that are considered too speculative
geologically to have the economic considerations a pplied to them that woul d enable them to be
categorized as mineral reserves, and there is no certainty that the PEA will be realized. The
Technical Report contains a full description of all underlying assumptions relating to the PEA.
Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

During the quarter the Company also complete d the installation signi ficant infrastructure
underground, including two new 55 kW ventilati on fans, a leaky feeder radio communication
system and extensions to the 11 kV power supply to the upper workings of the mine.
Grade Control and Stope Design
A total of 35 grade control holes (3,200 metr es) were completed underground by two diamond
drill rigs during the qu arter. In addition, a co mprehensive program of face sampling has been
undertaken, in which almost every development face which is within the known deposit is
sampled. This has resulted in almost 300 faces being sampled on the 1205 mRL, 1220 mRL and
1235 mRL levels generating over 1,300 samples. The results from grade control drilling and face
sampling have been used to upd ate the stope design model and pr ovide an updated estimate of
the tonnage and grade of the stopes it is planned to mine in the next six months.
A comparison of the tonnage and grade of th e first stopes between between 1205 mRL and 1265
mRL levels and from 59450 North and 59700 North - an area approximately 250 metres long and
60 metres high at the extremity of the known deposit (“Initial Mining Area”) has been carried out
between the original AMDAD design and the update d designs incorporating the grade control
information is provided in the Tables 2 and 3 below. The comparison breaks down the total
tonnage from the area into development tonnes and stope tonnes.
The AMDAD design defined a total of 44,073 tonne s at a grade of 6.83 g/t Au, containing 9,679
ozs in the Initial Mining Area. This tonnage comprised 33,539 tonnes at a grade of 6.71 g/t Au to
be mined from stopes and a further 10,534 tonne s at a grade of 7.20 g/t Au mined from
development of the 1205 mRL, 1220 mRL, 1235 mRL, and 1250 mRL levels. All of the material
in this initial mining area forms part of the Inferred Resource outlined in Table 4.
The more detailed design carried out by K92 inco rporating all of the results from the grade
control drilling and face samples has defined a to tal of 35,716 tonnes at a grade of 6.53 g/t Au as
remaining to be mined from stopes and 1,175 tonnes at a grade of 7.52 g/t Au to be mined from
the 1250 mRL level. This bei ng in addition to the 25,000 tonnes at a grade of 4.23 g/t that has
already been mined during the development of the 1205 mRL, 1220 mRL and 1235 mRL levels
over the last months, giving a total of 60,809 tonnes at a grad e of 5.58 g/t Au, containing 10,914
ozs within the defined area. This material has been defined by extensive grade control drilling
and face sampling of developments and is cla ssified as Measured Resource up to the1250 mRL
level and Indicated Resource between the 1250 mRL and 1265 mRL levels (see Table 3).
In summary:
Total tonnes defined by K92 grade control dr illing and sampling in the stopes are 6.5%
above that defined by AMDAD, while total tonnes from the above specified area are 38%
above those defined in the AMDAD model
The stope grade defined by K92 at 6.53 g/t Au (Table 3) is 2.7% below the 6.71 g/t Au
defined in the AMDAD design (Table 2)
The total contained ozs defined by K92 in the stopes (Table 3) is 3.6% above those
identified in the AMDAD design (Table 2), wh ile total ozs from the above specified area
are 13% above those identified in the AMDAD model.

The significantly higher tonnage of development material mi ned at lower grad e than predicted
from the AMDAD model is due primarily to the mi ning of lower grade material outside of the
defined stope areas which was identified duri ng face sampling. K92 mined and treated this
material as part of the commissioning process for the process plant.
Processing
The process plant throughput has ramped from just over 2,000 tonnes treated in January to
almost 12,000 tonnes treated in Ma rch. Despite treating only devel opment material assaying at
just under 4 g/t Au, the plant pr oduced saleable grade concentrat e during the enti re month of
March, with an average grade of 111 g/t Au. The final concentrat e produced has also averaged
almost 6% copper, which is over twice that produced by the previous operators. Unlike the
previous offtake agreements, the agreement wh ich K92 incorporates payment for copper, and
this level of copper increased the revenue for this first batch by approximately 4%. A total of 270
dry tonnes of concentrate was transported to the port of Lae during the month, while a number of
additional containers were loaded with concentrate and ready for transport to the port at the end
of the Quarter.
Recoveries have been steadily increasing as th e plant has moved towards steady state operations
and averaged 72% in March, despite the relatively low head grade. The plant demonstrated the
ability to treat in excess of 600 tonnes per day, while achieving grinds of in excess of 70% minus
45 microns, with only a light ball charge in the mill. This confirms the view of the Company that
the plant has significant excess capacity.
The newly installed and commissioned drum scr ubber is now fully operational and has allowed
the plant to treat extremely we t sticky mill feed from underground which would previously not
have been able to be handled by the crushing ci rcuit. The scrubber successfully removes all fines
and clays, allowing them to bypass the crusher and report to the milling circuit, while the coarse
fraction can be easily handled through the crushing circuit.
The new configuration with the dr um scrubber also provides significant flexibility to the process
plant, allowing the milling and flotation circuits to operate on feed from only the drum scrubber
undersize, only the crushed material from the Fine Ore Bin or a combination of the two.
During the quarter the Company purchased, installed, and comm issioned two 1,250 kW diesel
generators to provide complete standby power for the process plant, offices, workshop, and
camp. A third diesel generator located at the portal provides standby po wer for the underground
mining operations.

Exploration
Kora
The underground incline drive from the Irumafimpa Mine towards the Kora Deposit was
commenced during the quarter. This 5m x 5m driv e is designed to provide access to the Kora
deposit, where K92 is targeting the commenceme nt of production in First Half 2018, while also
providing the Company with the ability to drill test thereafter between Irumafimpa and Kora
from underground set ups. This area has not been previously tested due to topographical
challenges associated with drilling from the surf ace and is considered highly prospective given
the current interpretation of Irumafimpa and Kora being on the same vein structure.
Other
The Company completed the first phase of surf ace exploration work, including ridge and spur
soil sampling, rock chip sampling and creek traversing for the Pomasi Area 1 within EL’s
(Exploration Leases) 683 and 470 immediately to the north and west of the company’s ML
(Mining Lease) 150.
The exploration team have identified numerous qua rtz veins, which are potentially extensions of
the known mineralised vein systems (Irumafimpa/ Kora, Judd & Karempa) encountered within
ML 150. Selected results for this initial program are provided in Table 5.
Table 5 Pomasi Area 1 Selected Results
June Quarter
Mining in the June Quarter will focus on deve lopment along the deposit on the 1250 mRL level
between 59450 North and 59630 Nort h, together with access to, and development along, the
deposit on the 1205 mRl, 1220 mRL and 1235 mRL levels between 59700 North and 59950
North.
The mining production levels of 1,000 to 2,000 t onnes per month will be maintained in the
coming quarter from remnant stopes from the 1250 mRL and 1280 mRL levels. This will be a
combination of mining of broken material remaining from previ ous operations and blasting of
stopes which had been established or commenced by the previous operators.
New stope mining is scheduled to commence in May with material from the 1235 mRL to 1250
mRL stopes between 59450 North and 59700 North. The commencement of new stope mining
from the lower grade 1205 mRL and 1220 mRL leve ls is awaiting geotechnical input from
independent consultants to finalise the design and extraction schedules as the ground conditions
in this area is significantly different from that experienced in the rest of the deposit, requiring
modifications to the current design.
Ian Stalker, K92 Chief Executive Officer and Director, states, “The March Quarter has shown
solid progress and gives the Company confidence going forward. It is significant to note that that
three of the four stoping areas have recorded significant increases in both tonnes and contained

ozs in comparison to the AMDAD design and only one, the 1205 – 1220 stope area, which is at
the extremity of the known Irumafimpa deposit. While this is only the first stoping area and some
variability is to be expected within the mineral resource, it is nevertheless pleasing to see that in
this case as we move into upper stopes we consistently see more tonnes and contained ozs in our
grade control designs than from the AMDAD design, with the 1250 – 1265 stopes reporting a
50% increase in contained ozs”.
