Vancouver, British Columbia — December 17, 2025 — Leads & Copy — Tajiri Resources Corp. (TSXV: TAJ) reports initial trenching results from its Yono Gold Property, adjacent to the multi-million ounce gold deposits shared by G2 Goldfields Inc. and G Mining Ventures Corp.
Seven trenches were excavated to gather stratigraphic and structural data before the company received initial auger results. The trenches, except for YTR3, which tested better auger values along the northern boundary of the property, did not test the most anomalous auger results previously announced on October 7 and November 6, 2025. However, multiple zones of gold mineralization were intersected, including higher-grade intervals.
The style of higher-grade mineralization at Yono 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.
Trenching totaled 1,032 meters, and all reported intercepts are intersected widths, not true widths. Trench results are in the appended Table of Significant Intersections, and trench locations and mineralized intervals are in Figure 1.
Trench YTR2, 14 meters long, intersected 2 meters at 30.2 g/t Au from 10 meters, associated with quartz veinlets at the contact between a 4-meter-wide graphitic unit and volcaniclastics. The trench was dug near grab samples that returned up to 800 g/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 mineralization 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 80 meters 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.
Trench YTR4 intersected 2 meters at 41.3 g/t Au, with additional lower-grade intervals of 2 meters at 2.65 g/t and 3 meters at 1.2 g/t Au. The mineralization is associated with the contacts of a narrow west-dipping diorite and lies 20-40 meters to the west of a ~200-meter thick unit of carbonaceous siltstones. 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. Including all the mineralization between 34 and 53 meters (internal dilution of up to 8 meters), the combined interval gives a length-weighted intercept of 19 meters at 4.6 g/t.
Trench YTR3 returned 0.3 meters at 6.2 g/t Au from 80 meters on the eastern contact between a ~40-meter-thick unit of graphitic metasediments interbedded with volcaniclastics. The intersection confirms the contact is gold-bearing. Given the short strike lengths of mineralized 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 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 of 20 meters at 0.2 g/t Au from 34-54 meters, associated with the western contact of the graphitic metasediment unit. Mapping showed unsampled quartz-carbonate vein fragments in the upper portions of the trench, and west of ~65 meters along the trench geology strikes subparallel to the trench. The low-grade zone was interpreted to be wall rock mineralization of a vein zone striking subparallel to YTR3. Subsequently, YTR16 was excavated perpendicular to YT3.
Assays are pending for YTR16, but the trench intersected an intense zone of quartz carbonate veining and alteration of ~8 meters width (4-14m) with less intense veining and alteration present over its entire 20m length. 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.
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 6th, 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 notei). 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).
Trench YTR7 intersected 1 meter at 10.8 g/t Au, potentially extending mineralization 50 meters into Yono from the NE-trending Ghanie West Artisanal Working. The zone’s orientation, striking NNE, suggests it may be associated with a ~north-south striking splay structures related to the OKWD.
Trenches YTR1, YTR5, the central portion of YTR4, and YTR4A intersected lower tenor mineralization (e.g., 2 meters at 2.8 g/t & 6 meters at 0.6 g/t Au). These results demonstrate multiple mineralized zones within Yono that may improve along strike or down dip. Gold mineralization post-dates vein formation.
A 2,610-meter trenching program, targeting better auger anomalies, is underway. To date, 1,135 meters has been completed. Field operations will pause for Christmas between December 18 and January 12.
Trenching and mapping has identified duricrust and an underlying mottled zone capping a large portion of Yono. Test pits along YTR10 revealed that this zone of strong surficial gold depletion can reach depths of at least 12 meters. The company is evaluating power auger drilling and/or shallow RC drilling to effectively test gold anomalies beneath the duricrust cap.
Initial trenching has intersected multiple zones of gold mineralization with the potential to develop along strike or at depth.
Mineralization style associated with the higher-grade intercepts within Yono closely resembles that at OMZ where (as reported in Lewis et al 2025i) 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.
The company is assessing initiating high-resolution IP/Resistivity and/or TEM surveys in early 2026 to delineate graphitic units and locate potential sulphide accumulations associated with potential mineralization across Yono.
Mr. Graham Kevil, President and CEO of Tajiri, said the trench results confirm Yono hosts multiple zones of mineralization and high-grade gold localized in structural and stratigraphic settings analogous to those of neighboring deposits hosting multi-million ounce gold resources of G Mining Ventures and G2 Goldfields. Mr. Keevil said as exploration and understanding progress, the company’s confidence grows that Yono will play an important role in the ongoing development of these other regional deposits and has the potential to deliver significant new and material gold discoveries. The company looks forward to receiving further results from trenching and advancing to drill testing in 2026.
