Tajiri Reports First Yono Trenches and

Delivers High Grade Intercepts of 2m @ 41.3g/t

Gold; 2m @ 30.2g/t Gold; 1m @ 10.9g/t Gold

Vancouver, British Columbia--(Newsfile Corp. - December 17, 2025) - Tajiri Resources Corp. (TSXV:

TAJ) ("Tajiri" or the "Company") is pleased to report results of initial trenching from its majority-owned

Yono Gold Property contiguous to the multi-million ounce gold endowment

i

shared between the

properties of G2 Goldfields Inc.

"G2" and G Mining Ventures Corp. "GMin."

Seven trenches reported today were excavated, except for YTR3 which tested better auger values along

the northern boundary of the Property, to gather stratigraphic and structural information

prior to the

receipt of the Company's initial auger results.

Although the trenches reported today did not test the

most anomalous auger results previously announced October 7

th

and November 6

th

, 2025, multiple

zones of gold mineralisation were intersected including several higher-grade intervals.

Notably, the style of higher-grade mineralisation observed at Yono closely resembles that at G2's Oko

Main Zone ("OMZ"), where high-grade gold is hosted in narrow shear zones along contacts between

graphitic metasediments with other lithologies as reported in the 43-101 of Lewis

et al.

2025

i

.

All trench results are tabulated in the appended Table of Significant Intersections and the locations of

trenches and mineralised intervals are shown in

Figure 1

while a description of the methodology

employed in trench sampling is given after the Table of Intersections. The length of trenching reported

herein totals 1,032 meters and all reported intercepts are intersected not true widths.

Trench Highlights

i)

Trench YTR 2

a 14m long trench intersected

2m @ 30.2 g/t Au

from 10m (all trenches have been

sampled from west to east) associated with quartz veinlets associated with the contact between a

4m wide graphitic unit and volcaniclastics.

The trench was dug near previously reported grab

samples which returned up to

800g/t

, from quartz rubble in a small artisanal working.

The trench is

limited on its eastern side by a large area of alluvial workings.

The association of a narrow high-

grade interval with graphitic metasediments is comparable to mineralisation at OMZ and given the

location of the intersection in YTR2 near the projected extensions of the western zones at OMZ it

may represent a continuation of the western part of OMZ into Yono.

Approximately 80m of

prospective ground remains to the east beneath alluvial workings and the trench will be extended to

the west to close any potential across strike gap with YTR1.

ii)

Trench YTR4

intersected

2m @ 41.3g/t

Au

, together with additional lower grade intervals of

2m

@ 2.65g/t

and

3m @ 1.2g/t Au.

The mineralisation is associated with the contacts of a narrow

west dipping diorite and lie 20-40m to the west of a ~200m thick unit of carbonaceous siltstones

(see Figures

4

&

5

).

The contacts exhibit weak shearing, early deformed and later extensional

quartz and quartz carbonate veins. The western contact exhibits a marked zone of brecciation with

a matrix enriched in iron and manganese oxides together with minor fuchsite. If one includes all the

mineralisation between 34 and 53m (internal dilution of up to 8m) then the combined interval gives

a length weighted intercept of

19m @ 4.6g/t.

iii)

Trench YTR3

returned

0.3m @ 6.2g/t

Au from 80m on the eastern contact between a ~40m thick

unit of graphitic metasediments interbedded with volcaniclastics (see

Figure 2 A

).

While narrow,

the intersection confirms the contact is gold-bearing. Given the short strike lengths of mineralised

shoots at OMZ associated with significant resources (e.g. most of the ~ 500k oz gold resource in

Shear Zone 5 is contained within a strike a length of ~ 150m

i

and begins ~100m below surface) the

contact remains highly prospective to "blossom" along strike or down dip.

YTR3 also intersected a broader low-grade interval-

20m @ 0.2g/t Au from 34m-54m associated

with the western contact of the graphitic metasediment unit.

During mapping, given the presence of

unsampled quartz-carbonate vein fragments in the upper portions of the trench and that west of ~

65m along the trench geology strikes subparallel to the trench, the low-grade zone was interpreted

to be wall rock mineralisation of a vein zone striking subparallel to YTR3.

Subsequently,

YTR16 was

excavated perpendicular to YT3.

While

assays are yet to be received for YTR16 the trench intersected an intense zone of

quartz carbonate veining and alteration of ~ 8m width

(4-14m) with less intense veining and

alteration present over its entire 20m length (see

Figure 2B

).

Panning of several veins has returned

60->100 very fine eyes of gold but given the gold's grain size, veining may yet to be shown to be

only weakly mineralised.

Importantly mapping of YTR16 and YTR3 has revealed the unit of interbedded carbonaceous

sediments and volcaniclastics hosting the veins is strongly folded around late F2 or F3 fold axes

striking 065-075 and plunging southwest into Yono. The gold bearing quartz-carbonate veins

also appear to be fold controlled occurring along the foliation and contact parallel zones forming

axial planar, leg and saddle reefs. This structural configuration is similar to that given in

Figure 4

of

the Company's November 6

th

, 2025 press release (reproduced here as

Figure 3

) and is in strong

concordance with structural observations on the controls on mineralisation at both OMZ and GMin's

Oko West Deposit "OKWD" (as described in the 43-101s referenced in the end note

i

).

As such,

late F2/F3 folds have potential to both localise higher-grade mineralised shoots within generally

north-south striking structures and lithologies

and to host mineralisation along the ENE-WSW strike

and plunge of the late folds (see

Figure 4

).

iv)

Trench YTR7

intersected

1m @ 10.8g/t Au

potentially extending mineralisation 50m into Yono

from the NE trending Ghanie West Artisanal Working. However, the mapped orientation of the

zone- striking NNE- also suggests the zone may be associated with a ~north-south striking splay

structures related to the OKWD.

v)

Other Trenches

YTR1, YTR5, the central portion of YTR4 and YTR4A intersected lower tenor

mineralisation (e.g. 2m @ 2.8g/t & 6m @ 0.6g/t Au).

While modest, these results demonstrate the

occurrence of multiple mineralised zones within Yono that may improve along strike or down dip.

This is a marked feature of mineralisation in the Yono-Oko district where gold mineralisation post

dates vein formation as elucidated by Davis and reported in Lewis

et al

2025

i

:

Dead zones in veins are to be expected. This is because the veins are simply hosts but

pre-date the mineralisation. The intersection of a permeability network that has been

accessed by gold-bearing fluids after vein formation is necessary to produce zones of

significant mineralisation. As such, identification of competent hosts (i.e. the veins) and

the prospective shears is critical. Keep in mind that other competent hosts favourable for

formation of gold depositional sites (e.g. zones of alteration, rigid igneous intrusions,

homogenous and massive sedimentary units), may be present.

If all the criteria are present but grade isn't, it means we are on the prospective structure

and that more drilling is justified.

A lack of gold in assay means this is the cliché of a

technical success and that good grades may be very close by, just not in the small-

volume sample in the initial hole

.

Exploration Progress

Currently a

2,610m

trenching program, targeting better auger anomalies is underway. To date,

1,135 m

has been completed. Field operations will pause for Christmas between December 18 and January 12.

Trenching and mapping has identified duricrust and underlying mottled zone capping a large portion of

Yono (see

Figure 6

).

Test pits along YTR10 has revealed the duricrust and mottled zone and thus

potential zone of strong surficial gold depletion can reach depths of at least 12m.

As a result, the

Company is evaluating power auger drilling and/or shallow RC drilling to effectively test gold anomalies

beneath the duricrust cap.

Summary & Outlook

Initial trenching, despite being uniformed by auger results, has intersected multiple zones of gold

mineralisation with potential to develop along strike or at depth.

Mineralisation style associated with the higher-grade intercepts within Yono closely resembles that

at OMZ where (as reported in Lewis

et al

2025

i

) gold is concentrated in narrow high-grade shoots

along graphitic contacts.

Mapping of YTR16 suggest late ENE trending folding may play a key role in localising

mineralisation along structures and contacts of gross north-south strike and/or extending

mineralisation along the previously untested ENE strike direction.

A substantial strike length and thickness of graphitic metasediments is indicated within Yono,

extending from YTR3 in the north, through YTR4 and continuing southwards (

Figure 4

). Given the

strong control this lithology plays in hosting high-grade gold mineralisation at OMZ and the

confirmation that the contacts of the graphitic unit within Yono are mineralised, the entire strike

extent of this graphitic unit emerges as a large compelling first order exploration target within the

central area of Yono.

Given the presence and potential importance of the graphitic units within Yono to host significant

mineralisation, and that graphitic lithologies respond well to electromagnetic survey methods, the

company is currently assessing initiating high-resolution IP/Resistivity and/or TEM surveys in early 2026

to both delineate graphitic units and locate potential sulphide accumulations associated with potential

mineralisation across Yono.

President and CEO of Tajiri, Mr. Graham Kevil commented:

"These first trench results confirm Yono

hosts multiple zones of mineralization as well as high-grade gold localised in what can now be

deemed to be readily identifiable structural and stratigraphic settings. These settings are directly

analogous to those of the neighbouring deposits hosting the multi-million ounce gold resources

i

of G

Mining Ventures and G2 Goldfields. As our exploration and understanding progress, our confidence

grows that not only will Yono play an important role in the ongoing development of these other

regional deposits, but that Yono has potential to deliver significant new and material gold discoveries.

We look forward to receiving further results from trenching and advancing to drill testing in 2026."

Methodology

Trenches were dug by a 25 tonne New Holland excavator, rented by the Company.

Ground is first

cleared and soil and laterite overburden is removed to a depth 2-4m in an upper bench.

Thence the

trench is dug to a total depth of 6-7m (2-3m below the upper bench) to reach underlying saprolite where

possible.

Sampling is routinely conducted as horizontal channels taken on the south side of the trench along the

floor mostly as 2m continuous composites. The entire length of a trench is sampled and in areas of

potential interest the sampling interval may be tailored to the interval of interest with sample intervals of

1m or less if required (e.g. YTR3 @ 80-80.3m). Trench walls are cleaned prior to channel sampling,

preventing contamination from higher in the weathered profile.

All trenches are sampled from west to

east and intervals reported herein are referenced from the western end of trenches.

Orientations and positions of all reported trenches and intersections are shown in Figure 1 together with

the mineralised intervals referred to in the Table of significant intersections. Except for Trenches YTR6

and YTR7 all trenches were excavated in an east west orientation to cut inferred dominant north-south

striking zones.

Samples, weighing typically between 2-5kg, are bagged and labelled immediately after sampling and

stored on site until transport to either Actlabs or MSA laboratories in Georgetown Guyana, respecting

industry standard chain of custody procedures.

At Actlabs samples are dried and crushed to 80%

passing 2mm and a 250g aliquot is riffle split and pulverised and analysed by 50-gram fire assay. At

MSA labs a 1,000-gram aliquot is pulverised. Initial assay readings are by atomic absorption with

samples returning values greater than 3.0g/t being re-assayed with a gravimetric finish. The detection

limit for both laboratories is 5ppb.

The company inserts a QA/QC sample every 10

th

sample alternating

between duplicates, blanks and standards.

Bulk rejects and pulps are retained for 3 months for any

required re-assay after which bulk rejects are discarded and pulps retained.

Intercepts are reported with a maximum of 2m of internal dilution at a cutoff grade of 0.2g/t.

Internal dilution has only been applied to the intervals 36-

56m in YT3 and 212-218m in YTR5.

All intervals are given as the intersected widths and while strikes and dips of structures, contacts and veins

associated with mineralised intervals have been measured during routine mapping of the trenches, given the early nature of exploration and the fact

that vein orientations within shear zones commonly occupy an array or orientations often oblique to the true strike and width of a mineralised zones

we cannot at this stage give a true width for the mineralised intervals given in the above table.
