CleanTech Vanadium Reports up to 12.9 g/t Gold in Quartz Surface Samples and Presents a Conceptual Starter Pit at Its El Triunfo Gold Project in Bolivia

Wider channel samples generally returned lower gold values than samples selected directly from veins and structures.

Rhea-AI Summary

CleanTech Vanadium Mining (CTVFF) reported surface samples returning up to 12.9 grams per tonne of gold at El Triunfo in Bolivia. The February and July 2026 campaigns collected 37 samples. West Block quartz float—loose rock—returned 12.9 and 2.58 g/t gold; selected mine dump material returned 2.78 g/t gold and over 100 g/t silver.

The company is modeling a conceptual starter pit approximately 274 meters long, 105 meters wide and 20 meters deep, supported by four drill holes and 122 surface samples. It plans further sampling and tunnel rehabilitation to obtain material for metallurgical testing, which evaluates mineral recovery. Underground trial mining and regional processing may follow positive results. No resources, reserves or economic studies have been completed. Additional drilling is required; the float source and continuity between blocks remain unconfirmed. No regional processing agreements are in place.

Vancouver, British Columbia--(Newsfile Corp. - October 14, 2026) - CleanTech Vanadium Mining Corp. (TSXV: CTV) (OTCQB: CTVFF) ("CleanTech" or the "Company") is pleased to announce surface sampling gold assay results from two recent exploration campaigns at its El Triunfo Gold Project (the "Project"), located approximately 75 kilometers east of the city of La Paz, Bolivia. The Project comprises the El Triunfo West Block (the "West Block"), where the highest gold values from the 2026 exploration program were obtained and the El Triunfo East Block (the "East Block"). On the West Block, mineralization outcrops at surface along an east-west structural trend with a strike length of 750 meters, and the East Block is interpreted to represent a possible continuation of this structural trend approximately 1.5 kilometers to the east; however, continuity of mineralization between the two blocks has not yet been confirmed.

2026 Sampling Highlights

• A total of 37 samples were collected over two campaigns in February and July 2026. Sample TR-028 returned 12.9 grams per tonne ("g/t") gold and sample TR-029 returned 2.58 g/t gold from quartz float in the southwestern sector of the West Block. Nearby bedrock exposures suggest that the source of the gold-bearing float may be local, although the specific bedrock source has not yet been identified.

• Sample TR-022, collected from selected mine dump material from a prior artisanal mine working in the southern sector of the West Block, returned 2.78 g/t gold, over 100 g/t silver, over 1% lead, over 1% zinc and 0.17% copper.

• Several additional anomalous gold sample values were found in the southern sector of the West Block, including 1.89 g/t gold in sample TR-017, 0.72 g/t gold in sample TR-014 and 0.57 g/t gold in sample TR-016.

• Diamond drilling results on the West Block in the vicinity of the 2026 sampling locations included 98.9 meters grading 0.37 g/t gold, 22.71 g/t silver, 0.74% zinc and 0.58% lead from 13.0 meters downhole in drill hole TR-007, and 77.3 meters grading 0.31 g/t gold, 17.65 g/t silver, 0.57% zinc and 0.53% lead from 6.8 meters downhole in drill hole TR-008. Both TR-007 and TR-008 drill holes were drilled by Silver Elephant Mining Corp. ("Silver Elephant") in 2020.

• The Company plans additional sampling on the West Block to establish the continuity, orientation and width of the mineralized structures and to locate the bedrock source of the high-grade float samples.

Conceptual El Triunfo West Block Starter Pit

In light of gold and silver prices above US$4,000 and US$60 per ounce, respectively, the Company is modeling a conceptual starter pit on the West Block measuring a strike length of approximately 274 meters, 105 meters wide, and at 20 meters deep. The proposed starter pit area demonstrated extensive near-surface gold mineralization supported by gold assays from 4 drill holes and 122 surface samples.

Table 1. Drill Intercepts Within the Area Under Evaluation, West Block

TR-008	-70°	6.8	84.0	77.3	0.31	6.4 m at 1.60 g/t Au

 

Note: Intervals for drill holes TR-001 and TR-002, drilled by Solitario Resources between 2005 and 2007, were compiled by the Company from the historical Project database rather than taken from results published by Solitario Resources. The TR-001 interval is a gold-only interval and differs from the 94.2-meter polymetallic interval reported by Solitario Resources and described below. Results for drill holes TR-006 and TR-008 are as previously reported by Silver Elephant in its news release dated November 25, 2020. Reported lengths are downhole lengths and are not true widths. True widths are estimated at approximately 54% to 65% of reported lengths for drill holes TR-006 and TR-008 and are not known for drill holes TR-001 and TR-002.

As part of the starter pit modeling, the Company plans to rehabilitate existing tunnels where artisanal gold mining took place at the West Block. The aim is to extract mineralized materials in bulk from the tunnels for metallurgical testing. If the bulk sampling and metallurgical results are positive, the Company may undertake underground trial mining and evaluate the processing of mineralized material at regional toll milling facilities.

The desktop starter pit modeling is conceptual in nature. The Company has not estimated mineral resources or mineral reserves at the Project and has not completed a preliminary economic assessment, pre-feasibility study or feasibility study. Additional drilling will be required to confirm the continuity of the near-surface mineralization and improve geological confidence, and there is no certainty that the internal studies will result in the definition of mineral resources or support a decision to develop a starter pit. The conceptual starter pit dimensions are preliminary and may change.

Regional Processing Capacity

Several third-party processing plants operate in the Departments of La Paz and Oruro, approximately 130 to 320 kilometers from the Project, and represent potential toll milling options for bulk sample material. These plants include carbon-in-pulp and leach circuits designed for gold recovery, as well as flotation circuits that are potentially suited to the silver, zinc and lead content of El Triunfo mineralization. The regional plants are summarized in Table 2.

Table 2. Regional Processing Capacity Near El Triunfo

Plant	Location	Distance	Circuit	Capacity
Jacha Kollo (Grupo Minero Bonanza)	La Paz	130 km	Carbon-in-pulp  cyanidation,  desorption, refining	60 t/day
Planta de Lixiviación de Viacha (Cooperativa Aurífera Asunción Totoral)	La Paz	130 km	Gold leach	100 t/day
Colquiri (Corporación Minera de Bolivia)	La Paz	220 km	Gravity and differential  flotation, tin-zinc	2,000 t/day, plus  1,000 t/day existing
Bonanza Oruro / Minandina	Oruro	300 km	Flotation, three ball mills,  two circuits	100 t/day; 40 t/day  leach circuit under  construction
Ingenio Machacamarca (Corporación Minera de Bolivia)	Oruro	320 km	Flotation and gravity  concentration, tin	100 t/day

 

Note: Plant information has been compiled by the Company and has not been independently verified. Distances from the Project are approximate. The Company has not entered into any agreement with the operators of these plants, and the suitability of El Triunfo material for processing at any of these plants will depend on the results of metallurgical studies. There is no assurance that processing capacity will be available to the Company on acceptable terms or at all.

2026 Detailed Sampling Results

The first campaign, completed in February 2026, was focused primarily on the southern sector of the East Block, with additional reconnaissance and sampling in the southern part of the West Block. Fourteen samples, TR-001 through TR-014, were collected during this phase.

Guided by those results, the second campaign, completed in July 2026, was focused primarily on the southern sector of the West Block and extended farther into the southwestern sector of the West Block. Regional reconnaissance was also carried out in the northeastern part of the East Block. Twenty-three samples, TR-015 through TR-037, were collected during this phase.

Note: Select samples were collected from specific mineralized veins, structures or altered zones and are not necessarily representative of the full width or average grade of the mineralized structure. Float and mine dump samples do not represent in-situ widths. True widths of the mineralized structures have not been determined.

The sample locations and the distribution of the principal gold results are presented in Figure 2 below.

Gold distribution across the 2026 sampling is heterogeneous, with anomalous values concentrated within specific quartz structures and fault zones. Channel samples collected across wider intervals generally returned lower gold values than selective samples taken directly from veins and structures, indicating that the higher gold values identified to date are associated with specific mineralized structures.

El Triunfo Project Summary

The El Triunfo Project covers 256 hectares in the Department of La Paz, Bolivia. The Project is accessible by road year-round and has access to power and water. CleanTech holds an option, assigned to it by Silver Elephant in 2025, to acquire a 100% interest in the Project.

The Project area is underlain principally by a Paleozoic sequence of quartzites, siltstones and shales of the Amutara Formation, affected by folding and faulting. Regional structural trends are predominantly northwest-southeast, while mineralized structures observed within the Project area also show an approximately east-west orientation. Mineralization observed in the field is associated with quartz veins and veinlets up to 1 meter in width, silicified zones and fault structures, locally accompanied by pyrite, arsenopyrite, galena, chalcopyrite and sphalerite. In several areas the structures are partially covered by Quaternary and colluvial material, which limits the definition of their surface continuity and width.

Mineralized zones have been observed across widths of up to approximately 200 meters. The mineralized system may extend for over 2 kilometers along an east-west trend; however, the continuity of mineralization along this trend has not yet been confirmed.

A total of 13 drill holes have been completed on the Project: three by Solitario Resources between 2005 and 2007, five by Silver Elephant in 2020 and five, totaling 1,500 meters, by Silver Elephant in 2022. An induced polarization and resistivity survey completed in 2021 defined four principal geophysical anomalies, portions of which remain to be tested by drilling. The Project database contains 2,264 drill assay samples and 423 surface samples.

The West Block

The West Block hosts the principal known mineralization at El Triunfo. Mineralization is exposed at surface and has been identified over a strike extent of approximately 750 meters, with artisanal workings exposing mineralized structures along strike and down dip. Mineralization is hosted principally in altered black shales and occurs as quartz veins, veinlets and locally developed stockwork associated with fractures and faults, spatially associated with a regional anticlinal fold structure.

Solitario Resources drilled three holes on the West Block between 2005 and 2007, all of which intersected mineralization, including drill hole TR-001, which returned 94.2 meters grading 0.39 g/t gold, 21.8 g/t silver, 0.39% zinc and 0.65% lead, as reported in the Form 10-K filings of Solitario Resources with the United States Securities and Exchange Commission.

Silver Elephant's 2020 drill program suggests continuity of east-west mineralization over a minimum strike length of approximately 225 meters, with the results also suggesting that mineralization may remain open below 100 meters depth and along strike to the east and west. Drill hole TR-007 intersected 98.9 meters grading 0.37 g/t gold, 22.71 g/t silver, 0.74% zinc and 0.58% lead from 13.0 meters downhole, including 48.9 meters grading 0.42 g/t gold, 35.49 g/t silver, 1.17% zinc and 0.83% lead. Drill hole TR-008 intersected 77.3 meters grading 0.31 g/t gold, 17.65 g/t silver, 0.57% zinc and 0.53% lead from 6.8 meters downhole, including 6.4 meters grading 1.60 g/t gold, 56.49 g/t silver, 1.66% zinc and 0.94% lead.

Drill holes TR-009 and TR-010, completed in 2022 at the eastern and western edges of the West Block, respectively, both intersected mineralization, suggesting that the mineralized system may extend beyond the previously tested area. Drill hole TR-009 intersected 247.0 meters grading 0.2 g/t gold, 8.1 g/t silver, 0.14% zinc and 0.17% lead from 3.0 meters downhole, including 14.0 meters grading 0.8 g/t gold, 65.0 g/t silver, 1.44% zinc and 1.74% lead. Drill hole TR-010 intersected 45.0 meters grading 0.3 g/t gold, 8.7 g/t silver, 0.40% zinc and 0.58% lead from 7.0 meters downhole, including 1.2 meters grading 2.4 g/t gold, 61.4 g/t silver, 2.98% zinc and 10.80% lead. Selected drill results from the West Block are presented in Table 4, and drill hole locations are shown in Figure 4.

The East Block (Discovery in 2022)

In 2022, Silver Elephant discovered the East Block, which is interpreted to extend the West Block structural trend, approximately 1.5 kilometers to the east and separated from the West Block by a fault.

It shares a similar lithological sequence, comparable alteration and mineralization, a correlative anticlinal structure and the same bounding fault systems as the West Block. Surface channel sampling on the East Block returned up to approximately 1.8 g/t gold, and the subsequent induced polarization survey completed in 2021 identified an intense and continuous anomaly.

Three widely spaced holes drilled on the East Block in 2022, TR-011, TR-012 and TR-013, all intersected mineralization. Drill hole TR-013 intersected 25.7 meters grading 0.32 g/t gold, 22.2 g/t silver, 0.48% zinc and 0.73% lead from 64.3 meters downhole, including 8.0 meters grading 0.76 g/t gold, 41.1 g/t silver, 0.98% zinc and 1.45% lead. Drill hole TR-011 intersected 47.0 meters grading 0.18 g/t gold, 12.9 g/t silver, 0.22% zinc and 0.31% lead from 195.0 meters downhole, including 1.0 meter grading 1.39 g/t gold, 75.0 g/t silver, 2.35% zinc and 1.82% lead. Drill hole TR-012 returned several discrete intervals, including 2.0 meters grading 1.54 g/t gold, 12.1 g/t silver, 0.76% zinc and 0.47% lead from 234.0 meters downhole.

With only three widely spaced holes completed across its strike extent, the East Block remains substantially underexplored and warrants further exploration to better define the extent and continuity of mineralization. Selected drill results from the East Block are presented in Table 5.

Sampling, Analysis and Quality Control

Samples were collected by a consulting geologist under the supervision of the Qualified Person and delivered to ALS Global's laboratory in Oruro, Bolivia. Gold was analyzed using method Au-AA25, and multi-element analyses were completed using method ME-ICP41. No over-limit analyses were performed; accordingly, results exceeding the upper detection limits of the analytical methods are reported as greater than those limits.

The Company's quality assurance and quality control program for 2026 sampling campaigns included the insertion of one certified reference material (standard) into the sample stream. No blanks or field duplicates were inserted by the Company. Laboratory internal quality control procedures were also applied.

As described in Silver Elephant's news releases dated November 25, 2020, April 4, 2022 and January 12, 2023, drill core samples from the 2020 and 2022 drill programs were prepared by ALS Global in Oruro, Bolivia, and analyzed by ALS Global in Lima, Peru, with certified reference materials inserted into the sample stream.

FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What gold results did CleanTech Vanadium report at El Triunfo in 2026?

The highest result was 12.9 g/t gold in quartz float sample TR-028 from the southwestern West Block. Another quartz float sample, TR-029, returned 2.58 g/t gold. Selected mine dump sample TR-022 returned 2.78 g/t gold and over 100 g/t silver. The two campaigns collected 37 samples.

How large is CleanTech Vanadium's conceptual El Triunfo starter pit?

The conceptual West Block starter pit measures approximately 274 meters long, 105 meters wide and 20 meters deep. These preliminary dimensions may change. Additional drilling is required to confirm near-surface mineralization continuity, and the internal studies may not support a decision to develop the pit.

Where could CleanTech Vanadium process El Triunfo bulk samples?

Potential third-party processing options are in Bolivia's La Paz and Oruro departments, approximately 130 to 320 kilometers from El Triunfo. They include gold leaching and flotation facilities. Plant information has not been independently verified, no operator agreements are in place, and material suitability depends on metallurgical studies.
