NEWS RELEASE

K2 Drills High-Grade Gold at Mojave Project:

DF26-020 39.62m of 5.35 g/t Au;

DF26-019 10.67m of 7.75 g/t Au;

DF26-018 18.29m of 3.77 g/t Au

Vancouver, B.C. – August 18, 2026 – K2 Gold Corporation (“K2” or the “Company”) (TSX-V:

KTO; OTCQX: KTGDF; FRANKFURT: 23K) today announced the results of the first three drill

holes completed at the Mojave Project, as part of a fully permitted and fully funded 14,000 metre

campaign representing the largest drill program ever undertaken on the project . Results from

drilling at the first pad at the Dragonfly Zone confirm the presence of a high- grade oxide gold

system in a 40m step out hole north from K2’s 2020 discovery intercepts.

Highlights

• Results from all three holes reported herein are from site DF- A, a 40-metre step north

from K2’s 2020 highlight hole in the Dragonfly Zone, DF20-002: 45.72m of 6.68 g/t Au

(see K2 release of November 30, 2020);

o DF26-020: 39.62m of 5.35 g/t Au from 51.82m down hole, including 25.91 m of

7.14 g/t Au

o DF26-019: 10.67m of 7.75 g/t Au from 16.76m down hole

o DF26-018: 18.29m of 3.77 g/t Au from 27.43m down hole, including 7.62m of

7.48 g/t Au

o All three holes collared in a previously unknown gold zone with grades up to 0.96

g/t Au

• 15 holes completed to date for 2,630m of a fully permitted and fully funded 14,000m

campaign. Results from 12 additional K2 drill holes are pending.

• All holes drilled to date have intersected a well-mineralized system of sub-parallel, steeply

west-dipping structures hosting oxide gold.

• Mineralization at Dragonfly has been confirmed over 400m of drilled strike length and

remains open along strike and at depth. In addition to the main zone several parallel

structures have been identified by rock sampling.

• The Dragonfly Zone is located 1.5km south of the undrilled Gold Valley target (rock

samples to 375 g/t Au) midway along the >6.5km long Eastside Gold Trend, a broad

mineralized trend which has been identified by K2 sampling and limited historical drilling

(see NI43-101 Technical Report).

• The company will be hosting a live webinar Tuesday August 18 at 10am PST

John Robins, Executive Chairman of K2 stated: "We are exceptionally pleased with these initial

results. All work done to date on our 100% owned Mojave Project indicates the presence of a

very large mineralized system. The current drilling on the >6.5km long Eastside Gold Trend is

beginning to yield exceptionally high grades of oxide gold with multiple stacked mineralized

structures.”

“The strength of these initial drill results from Mojave reinforces our enthusiasm for the opportunity

we see across the project. Importantly, these first three holes represent a 40-metre step-out into

previously untested ground, demonstrating the potential to extend mineralization beyond our

previous drilling. With our 14,000 metre drill program continuing and assays currently pending

from 12 holes, we are excited about the results still to come,” stated Anthony Margarit, President

and CEO of K2 Gold.

Dragonfly Zone – Site DF-A

Dragonfly is centrally located in the middle of the Eastside Gold Trend 1.5km south of Gold Valley

and 2km north of Newmont, where high-grade oxide gold mineralization is hosted within a series

of steeply west-dipping structures. Ribs of silicified and strongly oxidized conglomerate, siltstone,

and limestone are exposed in the core of the target area and carry gold values of up to 22.53 g/t

Au. Surrounding the currently drilled portion of the target, s tacked, subparallel structures are

observed over a 400m wide corridor, with the majority undrilled to date.

K2’s initial drilling at the Dragonfly Zone was conducted from site DF- A, a 40m step north from

the highlight results of 45.72m of 6.68 g/t Au drilled in hole DF20-002 by the Company in 2020.

The 2026 holes represent the first drilling conducted in this segment of the Dragonfly Zone. Three

holes have been completed from Site DF-A, with drilling conducted at a 070° azimuth in an angled

fan: DF26-018 (-70° dip), DF26-019 (-50° dip), and DF26-020 (-85° dip).

All three holes intersected strong to moderate alteration starting shortly after collaring in a

previously unknown gold zone up to 0.96 g /t Au, with multiple zones of steeply west -dipping

mineralization occurring within a broad alteration envelope defined by a halo of silicification and

oxidation. Assay values for the individual samples ranged from trace to 14.9 g/t Au. At present

time, true widths of the mineralized structures at Dragonfly are unknown.

DF26-018

Hole DF26-018 drilled through a previously unknown gold zone and silicified conglomerate at

surface to 3.05m with grade up to 0. 61 g/t Au, before transitioning to a siltstone/shale unit with

variable iron oxides (goethite, hematite) and quartz -calcite veinlets to 21.0m. An alternating

mixture of sandstone and siltstone continues to final depth with pure calcite veins, quartz veinlets

and si licification, and oxidized finely disseminated sulphides. The sandstone/siltstone mixture

hosts strong gold mineralization with a moderate amount of iron oxides. Other observations

include the development of gypsum halos around quartz-oxidized sulphides, deep yellow, orange,

and red phyllitic siltstone. Increased iron oxides and fine- grained muscovite/illite are associated

with the phyllitic siltstones.

DF26-019

Hole DF26-019 collared on the same site as DF26-018 and drilled through a similar initial

sequence of conglomerate and sandstone. High- grade gold, 10.67m at 7.75 g/t, is associated

with the silicified and quartz -veined conglomerate starting at 16.76m to 27.43m. Starting at

79.25m the lithologies alternate from shale, siltstone, and sandstone with moderate to locally

strong iron oxides (goethite, hematite) in fractures, veinlets, and disseminated with or without

quartz veinlets. Several intervals of gold mineralization are associated with higher iron oxide

content starting at 79.25, at 94.49, 115.82m depths, each zone spanning 4.57 to 6.10 met res

thick.

DF26-020

Hole DF26-020, also collared from the same pad with a -85 inclination, drilled through the same

previously unknown gold zone for 6.1m with grade to 0.96 g/t Au. Like holes DF26-018 and DF26-

019, this hole cut interbedded shale, siltstone, sandstone, and minor conglomerates separated

by both natural depositional to fault-structural boundaries. The interval hosting gold mineralization

consists of bright yellow -orange (goethite) to purple- red (hematite) siltstone and orange- brown

sandstone cut by quartz veins and veinlets and occasional calcite. The interval is completely

oxidized. A segment of unoxidized siltstone with minor disseminated pyrite is intersected from

92.96 to 126.49m, then quickly transitions to an oxidized section of sandstone, shale, and siltstone

with minor intervals of gold mineralization up to 4.57m at 0.43 g/t Au from 128.02m depth.

Permitting

In early 2026, the Company received a positive Record of Decision (“ROD”) approving the Mojave

Exploration Drilling Program from the U.S. Bureau of Land Management (“BLM”) authorizing

exploration drilling from up to 22 drill sites.

The Company’s drilling program is proceeding under a comprehensive Plan of Operations that

aims to minimize environmental impact. Drill sites are limited in size, pads are constructed out of

timber to avoid extensive excavation, and all sites have been pr e-cleared by qualified biologists

and archaeologists after years of baseline work, avoiding all known cultural and biological

resources. In addition, Tribal Monitors from participating tribes are present at each drill site on a

24/7 basis. The current program constitutes the largest drill program ever undertaken on the

Mojave Project.
