CleanTech Vanadium Mining Corp. (TSXV: CTV | OTCQB: CTVFF) has released surface sampling gold assay results from two exploration campaigns at its El Triunfo Gold Project in Bolivia, with the highest sample returning 12.9 grams per tonne gold from quartz float on the West Block. The company has also presented a conceptual starter pit model for the West Block, citing gold and silver prices above US$4,000 and US$60 per ounce respectively as context for the modelling exercise. Investors may be watching closely as the disclosure marks a meaningful advancement in the company's early-stage exploration efforts at the 256-hectare Bolivian project.

Key Points

  • CleanTech Vanadium Mining Corp. (TSXV: CTV | OTCQB: CTVFF)
  • Surface sampling across 37 samples in February and July 2026 returned a peak result of 12.9 g/t gold from the West Block of the El Triunfo Gold Project in Bolivia
  • A conceptual starter pit measuring approximately 274 metres in strike length, 105 metres wide, and 20 metres deep has been modelled on the West Block; no mineral resource estimate or economic study has been completed
  • Investors should watch for results from planned additional sampling, tunnel rehabilitation, bulk sampling, and metallurgical testing at the West Block

High-Grade Surface Samples Highlight El Triunfo West Block Potential

A total of 37 surface samples were collected during two field campaigns at the El Triunfo project, located approximately 75 kilometres east of La Paz, Bolivia. Sample TR-028 returned 12.9 g/t gold and sample TR-029 returned 2.58 g/t gold from quartz float in the southwestern sector of the West Block. Sample TR-022, collected from artisanal mine dump material, returned 2.78 g/t gold alongside over 100 g/t silver, over 1% lead, over 1% zinc, and 0.17% copper. The company notes that the bedrock source of the high-grade float has not yet been identified, and the release states that gold distribution across the 2026 sampling is heterogeneous, concentrated within specific quartz structures and fault zones.

Conceptual Starter Pit Modelling Supported by Four Drill Holes and 122 Surface Samples

In response to elevated precious metals prices, CleanTech has modelled a conceptual starter pit on the West Block with dimensions of approximately 274 metres in strike length, 105 metres wide, and 20 metres deep. The area is supported by gold assays from four drill holes and 122 surface samples. Historical drill intercepts within the evaluated area include 34.3 metres grading 0.64 g/t gold in TR-001 and 81.1 metres grading 0.30 g/t gold in TR-002. The company emphasises that the modelling is conceptual in nature, no mineral resource or reserve estimate has been completed, and there is no certainty that a starter pit decision will result.

Regional Toll Milling Options Identified Across La Paz and Oruro

As part of its planning process, the company has identified several third-party processing plants in the Departments of La Paz and Oruro, located approximately 130 to 320 kilometres from the project. The facilities include carbon-in-pulp, gold leach, and flotation circuits, with individual capacities ranging from 40 to 2,000 tonnes per day. The disclosure states that the company has not entered into any agreement with any plant operator, and the suitability of El Triunfo material for processing at any of these facilities will depend on metallurgical study outcomes. There is no assurance that processing capacity will be available on acceptable terms.

West Block Tunnel Rehabilitation and Bulk Sampling Planned

CleanTech has stated its intention to rehabilitate existing tunnels at the West Block, where historical artisanal gold mining took place, with the aim of extracting mineralised material in bulk for metallurgical testing. The company indicates that positive bulk sampling and metallurgical results could lead to underground trial mining and evaluation of regional toll milling options. Additional surface sampling is also planned to establish the continuity, orientation, and width of mineralised structures. The immediate share price impact was not clear from available public information.
