Vancouver, British Columbia--(Newsfile Corp. - June 10, 2026) - Trinity One Metals Ltd. (TSXV: TOM) (FSE: 5D5) ("Trinity One" or the "Company") is pleased to provide an operations update on the Silver-1 Mine in Ecuador and Victory Project in Mongolia.

The Company is advancing Silver-1 through a multi stream technical program focused on systematic tailings sampling, waste rock evaluation and geophysical planning to generate priority diamond drill targets. In Mongolia, the Company has recently completed a three hole diamond drilling campaign at the Victory Project for a total of approximately 600 metres, with assay results pending.

Highlights

• Initial samples of tailings from Silver-1 returned 132.82 g/t silver and 0.58 g/t gold, and 118.47 g/t silver and 0.50 g/t gold.

• Initial waste rock sampling from the historic Silver-1 Mine area returned results including 405.27 g/t silver and 3.07 g/t gold.

• Trinity One is preparing a systematic tailings drilling and sampling program, currently expected to commence July 2026.

• Community engagement is advancing, with the Company targeting completion of the current engagement phase by the end of June 2026.

• The Company has completed a three hole diamond drilling campaign at the Victory Project in Mongolia for a total of approximately 600 metres and is currently awaiting assay results.

Thomas Wood, Chief Executive Officer of Trinity One, commented:

"Silver-1 is moving from historical review into modern field execution. Initial silver results from the tailings material are encouraging, particularly as the results received to date are broadly consistent with the historical 2007 sampling data.

"The Company is moving beyond initial sampling toward a systematic 15 metre by 15 metre tailings program designed to test the grade, thickness and continuity of the material across the tailings area. This work will give us a much clearer understanding of the scale, grade distribution and potential pathways to realise future value from the tailings.

"In Mongolia, we are pleased to have completed our three hole diamond drilling campaign at Victory. We now have two active technical workstreams across the portfolio, with assay results pending from Victory and further fieldwork expected from Silver-1."

Silver-1 Mine, Ecuador

The Silver-1 Mine is located in the historic San Bartolomé silver district of Ecuador. The project area contains historic mine workings, tailings, waste rock material and broader exploration potential.

The Company has recently completed a 3D mapping program over the project area, providing a modern base map to support planned sampling, geophysical work, future drilling and environmental planning. This work is expected to assist in defining access, surface features, historic workings, tailings geometry and future work areas.

The Company's current focus is the systematic evaluation of the project's tailings and waste rock areas, while advancing broader geological and geophysical diamond drill target generation across the project to define an NI 43-101 compliant resource.

Initial Assay Results

The Company has received initial assay results from recent sampling of tailings and waste rock material at Silver-1.

Initial tailings material returned:

Waste Rock Evaluation

The Company is also progressing evaluation of the project's historic waste rock areas.

Initial waste rock assays have returned silver, gold, lead and zinc values, including a sample grading 405.27 g/t silver and 3.07 g/t gold. The Company views these results as extremely encouraging and intends to undertake further systematic drilling and sampling of the waste rock areas.

The current waste rock work plan includes manual pits and surface sampling designed to provide an initial understanding of grade variability and material distribution. If results support further work, the Company may consider larger scale mechanical sampling or drilling based evaluation.

Initial waste rock samples returned:

The Company cautions that these results are from an initial and limited sample set and should not be considered representative of the broader tailings or waste rock areas. Further systematic sampling is required to determine grade distribution, continuity, thickness and potential tonnage.

Systematic Tailings Program

Trinity One is preparing a systematic drilling and sampling program over the Silver-1 tailings area. The Company plans to drill in a 15 metre by 15 metre grid, comprising approximately 35 sampling points across the tailings area. Sampling points are expected to be advanced to approximately 8 to 10 metres depth where ground conditions allow. Sampled at one metre intervals, the program is expected to generate approximately 350 samples, subject to final decisions regarding sample intervals and compositing. The objective of the program is to better define the thickness of the tailings, lateral and vertical grade distribution, potential tonnage, silver, gold, lead and zinc distribution, material characteristics, geotechnical conditions and potential future processing pathways.

The Company expects this program to be the first major modern systematic evaluation of the Silver-1 tailings area.

No mineral resource or mineral reserve has been established at Silver-1, and the Company is not treating the tailings as a current mineral resource or mineral reserve. Further systematic sampling, QA/QC, technical review and independent verification will be required.

Geophysics, Geotechnical Work and Target Generation

The company is advancing multiple geophysical and geotechnical workstreams at Silver-1. Current planning includes vertical electrical soundings over the tailings and waste rock areas to assist in understanding subsurface geometry, material boundaries, stratigraphy and depth potential. The Company is also progressing geotechnical assessment work, including evaluation of the tailings wall and related stability parameters.

In parallel, the Company is advancing drone magnetic survey planning. The objective of this work is to support both the tailings evaluation program and broader exploration targeting across the historic San Bartolome mineralized system.

The Company believes the integration of 3D mapping, geophysics, sampling and historical data will provide a significantly stronger platform for future drilling and exploration decisions.

Community and Environmental Work

Community engagement remains a central priority at the Silver-1 Mine. The Company's local team is progressing engagement with community members and local representatives in the San Bartolomé area. The current engagement phase is expected to continue through June, with the Company targeting completion by the end of the month.

Subject to successful completion of the current community engagement phase, the Company expects to commence the planned tailings drilling and sampling program in early July 2026. The Company is also evaluating the establishment of a fixed local presence in San Bartolomé to support ongoing community engagement, field operations and future technical work.

Trinity One has received approval for its basic environmental registry and has commenced further baseline registry processes. These processes are intended to document the current environmental condition of the project area and support future regulatory and field planning.

The Company is also progressing discussions with the Universidad del Azuay regarding potential technical and research collaboration.

Victory Project, Mongolia

Trinity One is pleased to report that it has completed a three hole diamond drilling campaign at the Victory Project in Mongolia.

The program totalled approximately 600 metres of diamond drilling and was designed to test priority targets generated from previous geological, geochemical and geophysical work.

Core from the program has been logged, sampled and submitted for laboratory analysis. The Company is currently awaiting assay results and will provide a further update once results have been received, reviewed and interpreted.
