Trinity Silver Reports Silver Grades of up to 82 g/t from Historical Nueva Chanarcillo Tailings

Vancouver, British Columbia--(Newsfile Corp. - October 19, 2026) - Trinity Silver Corp. (TSXV: TOM) (FSE: 5D5) ("Trinity" or the "Company") is pleased to report preliminary silver assay results from its initial tailings sampling programme at the Nueva Chañarcillo Silver Project ("Nueva Chañarcillo" or the "Project") in Chile's Atacama Region. Highlights Initial auger sampling returned silver grades of 37 to 82 g/t, averaging 55 g/t silver across 39 primary tailings samples. An excavator is currently on site, with a test pit scheduled to be excavated this week to collect a bulk sample for metallurgical testing. Follow up work will include systematic drilling and sampling to assess tailings thickness and grade distribution, together with density measurements and metallurgical testing to evaluate silver recovery. Trinity undertook the initial programme to assess silver remaining in the historic tailings and determine whether the results warranted more detailed drilling and metallurgical investigation. Samples were collected by auger drilling to a depth of approximately 1.5 metres. A single composite sample was collected over the entire drilled interval at each location, combining material from surface to the bottom of the hole. This approach provided an initial assessment of silver grades within the shallow tailings and a basis for planning further work. The 39 primary samples returned silver grades ranging from 37 to 82 g/t, averaging 55 g/t silver. The encouraging results support advancing the investigation through deeper drilling, systematic sampling and metallurgical testing. The initial holes did not establish the full thickness of the tailings. The results provide a basis for further investigation of silver remaining within the historic tailings, including assessment of deposit geometry and metallurgical characteristics. Further Evaluation Planned Following the encouraging initial results, Trinity is advancing a follow up programme to assess the scale and grade distribution of the tailings and investigate potential silver recovery. An excavator is currently on site and is scheduled to excavate a pit during the week commencing 19 October 2026 to collect a bulk sample for metallurgical testing. The testwork will assess how effectively silver can be recovered and help identify potential processing options. The planned programme also includes systematic drilling and sampling through the full tailings thickness to establish the base of the deposit and assess changes in silver grade across the site and with depth. Surveying and representative dry bulk density measurements will support a more reliable assessment of the quantity of material. The results will guide subsequent evaluation of the tailings. Metallurgical recovery and economic viability have not yet been established. Conceptual Tailings Exploration Target The Company is evaluating a proposed conceptual exploration target of approximately 135,000 to 270,000 tonnes grading 35 to 85 g/t silver within the historic tailings deposit. This is equivalent to approximately 152,000 to 738,000 ounces of contained silver before any allowance for metallurgical recovery. The potential quantity and grade of the exploration target are conceptual in nature. There has been insufficient exploration to define a mineral resource, and it is uncertain whether further exploration will result in the target being delineated as a mineral resource. The proposed tonnage range is based on a tailings footprint of approximately 42,270 square metres (4.23 hectares), delineated using ArcGIS by the Company's geologist. The calculation assumes an average tailings thickness of two to four metres and a dry bulk density of 1.6 tonnes per cubic metre. Multiplying the mapped footprint by these assumed parameters produces approximately 135,000 to 270,000 tonnes, rounded. The thickness range incorporates an initial two metre working assumption and subsequent field observations suggesting that exposed sections may approach four metres. These observations do not establish average thickness across the deposit. The basal surface has not been systematically delineated, and the density assumption requires confirmation through representative measurements. The proposed silver grade range of 35 to 85 g/t is based on rounding outwards the observed sample grades of 37 to 82 g/t. Its application to the wider tailings deposit remains an assumption to be tested through further drilling and sampling. The initial auger samples tested the upper approximately 1.5 metres of the tailings. Whether these results represent material at greater depth or in unsampled areas has not been established. The planned systematic drilling, sampling and density measurements will test the assumptions underlying the exploration target, which may change as further information becomes available. No mineral resource or mineral reserve has been established for these tailings. Metallurgical recovery and economic viability have not been demonstrated. Management Commentary Thomas Wood, CEO of Trinity Silver, commented: "The initial programme has returned encouraging silver grades and gives us a clear reason to advance our assessment of the tailings. With an excavator already on site, we plan to collect a bulk sample this week. We are also planning a further programme to better define the thickness and grade distribution of the material. "Our next step is to establish how effectively the silver can be recovered and develop a better understanding of the scale of the opportunity. This work complements our broader silver exploration programme at Nueva Chañarcillo."

The disclosure is based on preliminary laboratory results, the mapped tailings footprint and field observations. The unresolved sampling and estimation limitations are described above. The assumed average thickness, dry bulk density and grade continuity throughout the target volume have not been verified. Sampling, Analysis and Data Limitations The initial programme comprised 39 primary tailings samples collected by auger drilling to approximately 1.5 metres, with a single composite sample collected over the entire drilled interval at each location. The laboratory recorded received sample masses ranging from 5.5 to 15.0 kilograms for the 39 primary samples. Samples were submitted to Andes Analytical Assay SpA ("3AAA"), a commercial laboratory engaged by Metales de Chile SpA, for preparation in Copiapó and analysis in Quilicura, Santiago, Chile. Silver was determined by four acid digestion followed by atomic absorption spectrometry, with a lower reporting limit of 2 g/t silver. Quality control included blanks and duplicate samples, together with laboratory reference materials and repeat analyses. Control and duplicate results are excluded from the reported primary sample dataset and average grade. Coordinates are available for 33 of the 39 primary sampling locations. The remaining six samples lack recorded coordinates, limiting assessment of their spatial distribution. The initial sampling tested shallow tailings only, and silver grades through the full deposit thickness remain to be established.
