K2 Gold Strengthens Si2 Model - New Studies Define High-Priority Targets
K2 Gold Strengthens Si2 Model - New Studies
Define High-Priority Targets
Vancouver, British Columbia--(Newsfile Corp. - December 8, 2025) - K2 Gold Corporation (TSXV: KTO)
(OTCQB: KTGDF) (FSE: 23K) ("K2" or the "Company") today announced the results of comprehensive
geological studies that further reinforce the Company's Si2 Project as a compelling analogue to other
significant low-sulphidation epithermal gold deposits, including AngloGold Ashanti's Expanded Silicon
Project (16.3 Moz Au)
i
. Both K2 Gold's Si2 Project and AngloGold Ashanti's Silicon Project were
originally identified by the same project generator using its proprietary geological targeting methodology,
securing first-mover access to this previously overlooked epithermal target style
ii
.
"
At Si2, we have taken a disciplined, science-first approach to validating our geological model. The
results from both the fluid inclusion and alteration studies unequivocally demonstrate that our drilling
to date has only tested the upper level of a potentially much larger epithermal system
," stated Anthony
Margarit, K2's President and CEO. "
The data strongly indicate that by targeting deeper levels along
key fault structures, we may enter the productive boiling zone, similar to what is observed at other
world class deposits in the Walker Lane."
Highlights
Fluid inclusion study on quartz veining from 2023 drillholes confirms increasing temperature with
depth in the Si2 epithermal system (Fig. 1).
Results indicate that 2023 drilling terminated above the modelled "boiling zone", which typically
begins at fluid temperatures of >220°C.
Alteration study confirms Si2 is a classically zoned low-sulphidation epithermal system exhibiting
evidence for higher temperature fluid in the vicinity of the 2023 drilling.
Combined results indicate that the productive level of the epithermal system may lie immediately
beneath the extent of 2023 drilling.

Technical Summary
Why Are Epithermal Deposits Important
Epithermal systems are a major deposit class globally and in the western United States—including in the
Walker Lane of Nevada and eastern California—and have historically been important sources of gold
and silver due to their near-surface, structurally controlled mineralization. When preserved and not deeply
eroded these systems can host blind-to-surface, vertically zoned mineralization which may have been
historically overlooked. Defining and understanding this zonation (including locating the "boiling zone"
where precious metals precipitate) can reveal high-priority exploration targets.
Gold Deposition in Epithermal Systems
Precious metal deposition in epithermal systems typically occurs in what is known as the "boiling zone",
a depth at which hot, metal-rich fluids rising towards the surface begin to boil due to dropping pressure.
Fluid boiling results in the precipitation of the metals previously held in solution forming high-grade veins
and breccias. Boiling in typical low sulphidation epithermal gold systems occurs at temperatures of
>220°C, and most commonly between 230 and 240°C.
Fluid Inclusion Analysis and Microscopic Study
Through study of trapped inclusions or bubbles of hydrothermal fluid within quartz veins, the temperature
of the fluid can be determined, and depth of formation of the vein inferred. Vein formation temperatures
can aid in exploration targeting by revealing the level of the epithermal system encountered by drilling.
Fluid inclusions examined from six core samples reveal low-salinity (0.5-6 wt.% NaCl equiv.) aqueous
fluids trapped at temperatures of ~130-200°C, warming downwards through the core of the drilled
interval. These characteristics, along with microscopically observed vein textures, confirm the shallow-
level nature of the drilled interval and support the interpretation of a blind, deeper gold-bearing zone. No
evidence of significant boiling was observed in the inclusions, suggesting that the productive zone lies
below the depth tested.
Alteration Mineralogy & Structural Controls:
The alteration study, based on 108 spectral analyses from 95 drill core samples, delineates a classic
vertically zoned epithermal system, with a systematic transition from steam-heated alunite and
kaolinite/dickite at surface into progressively higher-temperature assemblages (smectite → illite-
smectite → illite → illite-chlorite).
Variations in illite abundance and locations of quartz-illite ± adularia
alteration suggest proximity to primary fluid pathways and fault-controlled mineralization.
The AOI1.5 fault in particular hosts an approximately 6 m thick quartz-veined interval at 200 m depth with
adjacent anomalous gold, indicating a strong target for follow-up drilling down-dip and along strike.
Exploration Implications and Next Steps
The combined datasets establish a clear, multi-layered vectoring model for follow-up drilling. Priority
targets include:
At depth and along strike of the AOI1.5 fault, where increasing gold values and deeper alteration
assemblages suggest proximity to the productive / boiling zone.
Beneath consistent gold mineralization encountered in hole SD-23-002, where quartz-illite +/-
adularia alteration vectors towards strong fluid pathways projecting to depth.
Deeper structural targets at AOI3, AOI4, AOI5, and AOI6—each of which exhibits extensive
advanced argillic alteration and anomalous mercury in rocks at surface.
Ongoing exploration work at Si2 includes a property scale geological mapping campaign and a planned
expanded IP survey, with results to support future drill targeting.
