Vancouver, British Columbia--(Newsfile Corp. - October 7, 2025) - Tajiri Resources Corp.
(TSXV: TAJ)
("
Tajiri
" or the "
Company
") is pleased to announce the first results from auger sampling at the majority
owned Yono Gold Project, Guyana, adjacent to ~8.9 million ounces of indicated and inferred gold
resources
i
at G2 Goldfields' (
G2
) Oko Main Zone (
OMZ
) and Ghanie deposits and G Mining Ventures'
("
GMin
") Oko West deposit ("
OKWD
").
To date results from approximately 60% of all the Company's auger sampling have been received and
these indicate
widespread gold anomalism across the entire property
.
Key Points
Peak Surface Results:
5.1 g/t, 1.3 g/t, and 1.6 g/t Au
from hand auger sampling within the
upper meter of a duricrust regolith (
Figure 1
).
Widespread Gold Anomalism:
Gold anomalies present on Yono compare favourably in scale
with those overlying OKWD (4.3Moz & 1.6Moz Au I & I resources
i
).
Almost the entire width of Yono
exhibits gold anomalism of 10-30ppb within which are embedded several highly anomalous zones.
The peak gold geochemical value returned from Yono compares favourably to OKWD which has a
peak soil value of ~
2.8 g/t
Au vs
5.1 g/t
Au
at Yono
(
Figure 2
).
Central Large Anomaly:
The largest indicated gold anomaly is the 1.5 km long "
Ridgeline
"
anomaly (Figures
2
,
3
&
4
) which runs diagonally through the entirety of Yono.
Ridgeline is
potentially a major mineralising structure associated and/or aligned with the following:
The centre line of the OMZ open pit and high grade resource- 700m north of Yono (
Figure 4
).
Average measured S2 Foliation at OMZ (
Figure 4
).
A major magnetic contact running through central Yono (
Figure 3
).
A substantial artisanal working to the southwest of Yono (
Figure 3
), indicating that Ridgeline
extends south beyond Yono.
Given Ridgeline is ~4km in strike, associated with substantial high grade gold resources, artisanal
workings, surface geochemical anomalism, and a major geophysical structure within Yono, it is
reasonable to assume that Ridgeline overlies a significant mineralising structure of which 1.5km strike
potential lies within Yono.
Multiple Additional Targets (see
Figure 3
):
Ghanie West Extension:
780m strike, 50-100ppb Au, extending from the Ghanie West
vein zone working, immediately adjacent to the Project - trending SW-NE through the south of
the Project and associated with a distinct magnetic contact.
The Splay:
580m strike with peak auger values of 5.1 g/t and 1.6 g/t Au.
The zone parallels
the gross orientation of the magnetic high whose contacts host Ghanie West and Ridgeline.
The Splay follows co-incident magnetic (weak internal) and strong topographic lineaments.
'Tweener:
1,000m strike, 30-375ppb Au, apparent source of significant alluvial & colluvial
gold workings, located within a region of low magnetic susceptibility, located between
Ridgeline and High Road.
High Road (Down-dip extensions):
950m strike, located on GMin's tenure, immediately
west of Yono, comprised of anomalous soil and shallow scout RC samples, likely dipping
into the property.
ii
Total Strike Potential:
~
4.8 km of anomalous gold-zones
identified within and immediately
adjacent to Yono.
Chairman's Comment
Mr. Dominic O'Sullivan commented:
"Today is very exciting for the Company and our supporters.
For me the big take home is revealed in
Figure 2
, where Yono can be seen to lie unequivocally within the same domain of gold enrichment,
that hosts nearly 9 million ounces
i
along Yono's eastern flank.
"Considering all the facts:
Widespread gold anomalism, multiple zones of higher gold anomalism
approaching 5 km in strike, a good smattering of high-grade results coughing out of a regolith where
strong leaching of surface gold is expected; Yono's potential to host the next discovery in the
developing Tier 1 Yono-Oko gold district, should not be underestimated."

Moving Forward
The Company expects to report further auger results and results of the initial trenching program as they
become available. Thereafter, the company will undertake further trenching to follow up today's discovery
with a view toward prioritizing targets and drill planning in the due course.
Regolith Regime — Significance for Results and Further Information
Mapping of Regolith during the Company's programs confirmed the majority of Yono is covered by a 2-
4m thick indurated duricrust (Figures
5
&
6
).
Consequently, most hand-auger holes did not reach the
targeted stone line horizon at the interface between laterite & mottled zone saprolite/bauxitic zone and
only attained depths of 20-60cm.
This is in distinct contrast to regolith regime overlying OKWD which is
a residual laterite.
As such, and as illustrated in
Figure 5
, the differing regolith regimes should make for
to a very muted geochemical response in the duricrust encountered at Yono compared to the residual
regolith immediately overlying OKWD.
Reunion Gold Corp. (predecessor and discoverer of OKWD) in their 2023 press release noted the
leached nature of the duricrusts in the district:
"Soil geochemistry was an important tool used in the discovery of the Kairuni zone
iii
however, in the
western portion of the PL, a thick duricrust cover combined with alluvial material in drainages, has
limited the effectiveness of the initial soil geochem program completed in 2020. SRCGP
iv
was
designed to address this by drilling 10 to 20 m deep RC holes to penetrate this
leached
cover
material and sample the saprolite beneath."
Further, as exemplified by the selected quotes from Voormeij's monograph given in the footnote below;
v
duricrusts regimes and their overlying soils are globally highly depleted / leached of gold, with the
consequence that surface values of 25-50ppb Au may overly significant gold ore bodies.
Consequently,
the widespread gold anomalism encountered at Yono, in addition to discrete zones of higher anomalism,
may be significant and warrants extensive follow-up sampling below the duricrust.

Methodology
Hand auger samples were collected on an initial grid of 400 x 50m which was later infilled to 200 x 25m.
Sample lines were oriented east-west.
Auger samples were taken with a 3-inch diameter hand auger,
with samples collected every vertical meter (or portion of a meter).
Where possible auger holes were
drilled to the stone line (interface of laterite and mottled zone saprolite) which in the area averages 2-4m
depth. However, most auger holes did not reach target depth with many only being able to penetrate to
20-60cm. Sample weights ranged from 1-4kg and after collection, samples were stored in a secure
facility at the Yono Project Site.
Entire auger samples were sent to either Actlabs or MSALABS, in
Georgetown, Guyana; both accredited mineral analysis laboratories.
Samples were assayed via 50g
charge, fire assay with atomic absorption finish.
Lower detection limit is 3ppb Au.
No certified gold
reference standards were inserted by the Company (we await shipment of such standards) however,
both MSALABS and Actlabs routinely assay internal standards and blanks, and the company inserted
blanks and field duplicates (every 20th sample).
On this basis no QA/QC issues were noted with the
results reported herein.

notes the following:
"
Duricrust:
The top of a hard cap associated with duricrust, typically capping hills and forming plateaux
will be greatly leached of
metals
. Laterite or saprolite beneath the duricrust, if it can be reached through augering or pitting, will make a better sampling medium
than the soils overlying duricrust....... To ensure collecting a soil medium (S) that can indicate potential blind/underlying gold
mineralization, the duricrust must be broken through and the base of the laterite sampled…
…
....
Too often, projects have been passed on because of the low gold grade in soil assays (e.g. 25-50 ppb Au), when it could
be the low-grade mushroom cap that is part of a large economic primary gold deposit
, potentially with supergene oxide
enrichment zones. Trenching and pitting is conducted to test for the source of significantly sized gold dispersal halos identified in the
soils....."
.......
Residual:
The entire laterite regolith is intact and is formed in situ. Upland areas in undulating topography are often residual.
Soft
laterite cap with a healthy set of upper soil horizons will provide good sampling medium
in the overlying B Horizon....."
