K92 MINING INC.

K92 Production Ramps Up and Exploration Dr illing to Commence to Follow Up on Kora

Extension Discovery Hole

 Stope production achieved from the Irumafimpa deposit

 450 tonnes of gold copper concentrates shipped during July with another 250 tonnes

of gold copper concentrates sent to port and available for shipment

 extensive program of diamond drilling to commence early August from

underground set ups along Kora Drive, designed to follow up on Kora extension

discovery hole

 Continued regional exploration at the Poma si Project adjacent to the Mining Lease

(ML150) on EL 693 and 470 with multiple hi gh grade values returned and multiple

veins identified, including an interpreted extension to the Irumafimpa vein system

K92 Mining Inc. (“K92”) continues to ramp up production at the Irumfimpa Mine, is about to

commence exploration drilling from underground set-ups to fo llow up on the recent Kora

extension discovery hole, is preparing to mine and test a 2,000 tonne bulk sample from Kora and

continues regional exploration on the Pomasi Project.

Irumafimpa

K92 has, up until recently, been mining from deve lopment areas. Now, K92 is also mining from

production stopes where higher gold and copper grades are anticipated.

Long hole stope production has commenced from the newly developed 1235mRL to 1250mRL

stope area. It is anticipated th at the commencement of this ne w stope production, combined with

ongoing production from development and remnan t stopes will allow commercial production to

be achieved in September.

Additionally, extraction of material from planned stope s 1205S, 1220S and 1235S, which were

awaiting geotechnical input from independent consultants to fina lise the design and extraction

schedules (as per K92 News Release, May 16, 2017) is scheduled to commence in the coming

quarter. Extraction in this area will apply a combination of long hole stoping and flatbacking (cut

& fill) depending on access and geotechnical considerations.

Development above the 1250 mRL is planned in th e current quarter whic h is anticipated to

provide development feed to the mill from the 1250 and 1265 mRL levels with commencement

of stoping from these levels in the Q4 2017.

Further, grade control drilling has identified additional stoping material below the previously

planned lower limit of 1205 mRL and planning is underway to commence acc essing this area in

the Q4 2017. Further grade control drilling is also planned in this area as the limits to the down

dip extension of the mineralization has yet to be determined.

To date, approximately 7,000 metres of grade control drilling has now been completed at

Irumafimpa, which means the company has grade control drilling for the next 3 months of

production. Continuing with grade control drilling and staying ahead of production is key within

K92’s strategy of efficiently mining Irumafimpa.

Kora

Based on the recent high grade discovery of the Kora Deposit extension, the design of the Kora

Exploration Drive has been enhanced to inco rporate the development of a footwall drive

approximately 50 metres from the projected strike of the Kora Vein System as shown in Figure

1. This modification allows the development of dr ill cuddies approximately 100 metres closer to

the interpreted position of the Kora Vein System than previously planned, based on the results

from diamond drill hole KMDD000 9 which recorded an inters ection of 5.4 metres @ 11.68 g/t

Au, 25.5 g/t Ag and 1.33 % Cu from 154 metres downhol e, interpreted to be the discovery of an

extension of the Kora deposit (see K92 News Release May 24, 2017 for drill result details).

In addition to providing set ups for explorat ion drilling, this development will allow a bulk

sample (~2,000 tonnes) of the Kora deposit to be mined as early as September 2017 for testing

and evaluation purposes.

A total of approximately 120 metres of development of the Kora E xploration Drive, access drive

and footwall drive was completed during July. The first drill cuddy in the footwall drive will be

completed in early August and drilling is pl anned to commence from this cuddy immediately

following its completion. The company has also arranged the mobilization of a third more

powerful underground diamond drilling rig from its contractor which is expected on site in

September. This rig will allow holes of up to 900 metres to be drill ed from underground,

targeting rapid execution of the company’s planned exploration and expansion work.

Additional to the work underground, K92 is also in the process of re-logging core from drilling

at Kora conducted by previous operators. Of no te, in the re-logging to-date, are high grade

intercepts previously unreported by K92 such as diamond drill hole 080BD04 with 0.3 metres @

15,350 g/t Au (1.5%) from 50.7 metres (no top cut) and BKDD0015 with 0.3 metres @ 6,380 g/t

Au and from 62.4 metres (no top cut). Re-logging of the Kora core will assist and guide K92 as it

embarks on more aggressive Kora exploration a nd expansion drilling in the coming weeks and

months.

K92 has filed and made available for downloa d on the Company’s SEDAR profile, a technical

report titled “Independent Tech nical 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”).

The PEA estimates for Kora, based on the current Inferred resource , estimates (4.36 million

tonnes of 7.3 g/t Au, 35 g/t Ag and 2.23% Cu);

 Over a 9 year operating life the plant would treat 3.2 million Inferred tonnes averaging 7.1

g/t Au, 25 g/t Ag and 1.7% Cu (9.3 g/t AuEq*)

 this would generate an estimated positive cash flow of US $537 million using current metal

prices if 15m levels are used in mining. If 25m levels are used then net cashflows are

estimated as US $558 million. This cashflow includes conceptual allowances for capital

 production of an estimated average of 108,000 AuEq* ozs per annum over an 8 year period

from Year 2 through to Year 9

 An estimated pre-tax NPV of US $415 million for 25m levels; or US $397 million for 15m

levels; using current metal prices, exchange rates and a 5% discount

 an estimated after-tax NPV of US $329 milli on for 25m levels; or US $316 million for

15m levels; using current metal prices, exchange rates and a 5% discount

 initial capital cost is esti mated to be US $13.8 million, including the US $3.3 million for

the plant upgrade identified in the Mincore Scoping Study but excluding the proposed Kora

exploration inclines and diamond drilling. Sustai ning Capital Cost is estimated to a further

US $64 million spent over the life of the Kora mining for 25m levels or US $83 million for

15m levels

 operating cost per tonne is estimated to be US $125/tonne for 25m levels or US $126 /

tonne for 15m mining levels

 excluding initial capital expenditure of US $14 million, cash cost is estimated to be US

$547 / oz AuEq (inclusive of a 2.5% NSR) and AISC of US $619/oz AuEq for 25m mining

levels; or US $549/oz (inclusive of a 2.5% NSR) and AISC of US $644/oz AuEq for 15m

mining levels

Metal prices used were Au – $1300/oz; Ag – US $18/oz; Cu – US $4800/tonne

*AuEq calculated on above metal prices

Kora remains open for expansion in every direction and strongly mineralized at the extent of all

drilling.

The PEA is preliminary in nature and includes inferred mineral resources that are considered too

speculative geologically to have the economic consid erations applied to them that would enable

them to be categorized as mineral reserves, and there is no certainty that the PEA will be

realized. The Technical Report cont ains a full description of all underlying assumptions relating

to the PEA. Mineral Resources that are not Mineral Reserv es do not have demonstrated

economic viability.

Regional Exploration

Exploration outside of ML 150 is currently focu sed on the Pomasi Project area adjacent to the

Mining Lease (ML150) on EL 693 and EL 470 w ith work moving from Pomasi Area 1 to

Pomasi Area 2, see Figure 2 below. The work has included:

o Prospecting, sampling, mapping and assessment of the mineralised veins;

o Mapping of the geology within the drainage systems and surface exposures, and linking

them with the prospected veins;

o Conducting a ridge and spur soil sample survey for indications of anomalous

geochemical dispersion from the auriferous veins across a select number of ridges and

spurs;

o Trenching along the length of identified veins to establish widths, grades and strike extent

To date results have included multiple high grade values (previously reported) and the

identification of multiple high grade veins including an interpreted extension to the Irumafimpa

vein system. These results have also identified a number of gol d and copper targets from soil

sampling analysis, which will be followed up in the next phase of work.

The Company plans to fly a detailed aerial ge ophysics program over its Mining and Exploration

Leases. While limited aerial geophysics has prev iously been undertaken in 1982 and again in

2008, K92 and its consultants have evaluated the data and found it to be of generally poor quality

with very limited ground penetration. This survey is considered as an essential tool for the

identification of extensions to existing deposit s as well as better defining existing vein and

porphyry targets and identifying potential new targets.

Ian Stalker, K92 Chief Executive Officer and Director, states, “Moving from mining

development material into stope material is a major positive for our Irumafimpa mining

operation. With mining and processing going well and with the production ramp up progressing,

shareholders can also look forward to the commencement of explor ation drilling to follow up on

the recent Kora extension discovery hole. The combination of production alongside of

exploration targeting high impact expansion and disc overy will provide significant news flow in

the coming weeks and months.”
