NEWS RELEASE

K92 MINING ANNOUNCES STAGE 2A EXPANSION TO INCREASE THROUGHPUT

+25% TO 500,000 TONNES PER ANNUM AT KAINANTU GOLD MINE

• Stage 2A expansion underway to increase annual throughput by +25% to 500,000

tonnes per annum (“tpa”) or 1,370 tonnes per day (“tpd”) from 400,000 tpa or 1,100

tpd.

• Performance of existing process plant has already shown the ball mill is capable of

well above 400,000 tpa (1,100 tpd). Since Stage 2 Plant commissioning in 3Q 2020, the

mill has consistently demonstrated an ability to deliver a notably finer than required

product size, while also achieving up to 28% higher through put with a single day

record of 1,408 tonnes processed on September 22, 2021.

• Plant expansion involves low capital cost upgrades with an estimated capital cost of

US$2.5 million and full commissioning to commence in 3Q 2022. Several expansion

items have already arrived on site, and the expansion involves the following:

o Additional filter press on site and being commissioned.

o Additional T-1000 crusher expected to be installed in 4Q 2021.

o Additional flotation cells, pipes and pumps expected to be installed in 2Q 2022.

o Underground mobile equipment and development capital expenditures to be

accelerated from Stage 3 Expansion capital and expected to arrive during 1H

2022.

• Stage 2A Expansion decision was also supported by strong exploration and

development results along the Judd Vein System. Judd represents a new mining front,

proximal to existing infrastructure at Kora, and is expected to provide a notable boost

to operational flexibility and mining efficiencies.

• The expansion is expected to further drive economies of scale , increase potential

production, and strengthen K92’s ability to self -fund the Stage 3 Expansion . The

Stage 3 Expansion Definitive Feasibility Study is well underway.

Vancouver, British Columbia, October 7, 2021 - K92 Mining Inc. (“K92” or the “Company”)

(TSX: KNT; OTCQX: KNTNF) is pleased to announce that its Board of Directors has approved

the Stage 2A Expansion, expanding the annual processing throughput to 500,000 tonnes per annum

at its Kainantu Gold Mine in Papua New Guinea. This represents a +25% increase from the Stage

2

2 proc essing capacity of 400, 000 tonnes per annum. Full commissioning of the Stage 2A

Expansion is expected to commence in 3Q 2022.

The decision to proceed with the Stage 2A Expansion is based on the strong performance of the

process plant to date. The process plant has strongly demonstrated that it is capable of a throughput

rate well in excess of 400,000 tpa (1,100 tpd), delivering a mill product size that is notably finer

than required while also achieving multiple daily throughput records, including a single day record

of 1,408 tonnes processed on September 22, 2021.

The Stage 2A Expansion decision is further bolstered by the strong exploration and development

results from the Judd Vein System. Judd is located near -mine infrastructure, subparal lel to and

~150-200m east from the producing Kora deposit , within the mining lease and with similar

metallurgical characteristics to Kora. The proximity of Judd to Kora enables Judd to utilize Kora’s

incline and its footwall drive along strike while also being decoupled from Kora’s mining cycle ,

resulting in considerable development , mining and mine planning efficiencies. Judd produc tion

stoping is planned to commence this quarter, providing a near-term boost to mining throughput.

The incremental capital investment to complete the plant expansion is estimated to be US$2.5

million. Several upgrades have already been ordered or installed, with a new filter press being

commissioned and an additional T-1000 crusher to be installed this quarter. Key outstanding items

are additional flotation cells, pipes and pumping , which are expected to be installed in 2Q 2022 .

Mobile equipment and development capital expenditures will be accelerated from Stage 3

Expansion capital, with equipment expect ed to arrive during 1H 2022 . Stage 2A Expansion will

be funded from existing cash flows from the current Kainantu Gold Mine operations.

John Lewins, K92 Chief Executive Officer and Director, stated, “Expanding the existing process

plant to 500,000 tonnes per annum is a major positive development for the Kainantu Gold Mine .

Importantly, at an estimated plant expansion capital cost of US$2 .5 million, the expansion is not

only funded from existing cash flow but is also expected to considerably strengthen our near-term

ability to self-fund the Stage 3 Expansion while continuing to advance our vein field and porphyry

exploration.

In addition to the strong performance of the process plant to date, a notable driver for the Stage

2A Expansion decision has been the significant exploration and development results at Judd. Judd

is near existing Kora infrastructure making it highly efficient to access, while also being essentially

decoupled from Kora and has similar metallurgical characteristics. These attractive features make

mining Judd and its mine planning highly efficient . The first production stope at Judd is planned

to be mined this quarter and is expected to provide a notable boost to the ramp -up of mining

material movements, which were particularly impacted earlier in the year by COVID-19.

Judd is also highly efficient to explore, as it is not only proximal to Kor a but utilizes the same

diamond drill cuddy infrastructure that has been established over the last four years at Kora. With

infill drilling nearly complete at Kora, at least two-thirds of the underground drill rigs are planned

to be allocated to Judd by la te-October, marking the first major exploration program of the vein

system.

Lastly, we remain on track for the next Kora resource estimate update planned for late -2021 as

well as the release of a maiden resource estimate for Judd . The Stage 3 Expansion Definitive

Feasibility Study is also progressing well and f indings from certain studies and test work have

presented opportunities that will be implemented as part of the Stage 2A Plant Expansion.”
