ECRTF OTC Link

Company Description

ECRTF is the OTC symbol associated with ATEX Resources Inc., a mineral exploration company whose primary focus is the Valeriano Copper-Gold Project ("Valeriano" or the "Project") in the Atacama Region of Chile. According to company disclosures, Valeriano is a copper-gold porphyry project located within an emerging copper-gold porphyry mineral belt that links the prolific El Indio High-Sulphidation Belt to the south with the Maricunga Gold Porphyry Belt to the north. This emerging corridor, informally referred to as the Link Belt, hosts several copper-gold porphyry deposits at various stages of development.

ATEX describes Valeriano as hosting a large copper-gold porphyry mineral resource, with exploration centered on both the main porphyry system and an overlying high-grade breccia discovery known as the B2B Zone. The company reports that the B2B Zone is a high-grade breccia body with copper-gold mineralization situated above a high-grade porphyry corridor, and that drilling has outlined a strike length on the order of several hundred metres with the zone remaining open in multiple directions. Within the broader Valeriano Porphyry footprint, ATEX has also defined a continuous high-grade trend of bornite- and chalcopyrite-bearing mineralization, sometimes referred to in its releases as the high-grade porphyry trend or corridor.

Valeriano Copper-Gold Project Focus

Company news releases state that exploration at Valeriano is being advanced through a series of multi-rig drill campaigns. These programs have included:

  • Phase IV drilling, which contributed to the discovery of the B2B breccia zone and extended mineralized porphyry intervals.
  • Phase V drilling, described by ATEX as the largest and most successful exploration program at Valeriano to date, with approximately 16,600 metres of directional diamond drilling completed and multiple daughter holes testing both breccia and porphyry targets.
  • Planning for a Phase VI drill program, with stated objectives that include further delineation and growth of the B2B Zone, testing additional breccia-style targets, expanding the Valeriano Porphyry system, and ongoing project de-risking work such as baseline environmental studies, early-stage engineering studies, and permitting for future drill campaigns.

Across these phases, ATEX reports numerous long intervals of copper equivalent (CuEq) mineralization in both breccia and porphyry settings, calculated using metal recoveries and prices disclosed in its technical materials. The company refers to an NI 43-101 technical report titled "Independent Technical Report for the Valeriano Copper-Gold Project, Atacama Region, Chile" with an effective date of September 1, 2023, which provides additional detail on the 2023 Mineral Resource Estimate for the project.

Exploration Strategy and Techniques

According to its news releases, ATEX employs directional diamond drilling, including the use of parent and daughter holes, to efficiently test targets at depth and along strike. The company states that this approach has allowed it to save thousands of metres of drilling compared to conventional methods, while increasing the density of drilling in key target areas. Drill programs have been designed to:

  • Delineate the high-grade B2B breccia zone and evaluate its geometry, scale, and vertical and lateral continuity.
  • Extend and infill the high-grade porphyry trend within the Valeriano Porphyry footprint, including step-outs along strike and into previously untested areas.
  • Test the broader porphyry footprint, encompassing Early and Intermineral porphyry phases, through infill and step-out drilling where system limits are described as still unknown.

Company disclosures also describe the use of multiple drill rigs, staged demobilization and remobilization between phases, and the integration of geological, geophysical, and metallurgical data to refine the geological model. ATEX notes that data from the B2B discovery has generated additional B2B-style targets to be evaluated in future exploration.

Project Setting and Regional Context

In its "About ATEX" sections, the company emphasizes that Valeriano lies within an emerging copper-gold porphyry belt in Chile’s Atacama Region, informally called the Link Belt. This belt is described as connecting the El Indio High-Sulphidation Belt with the Maricunga Gold Porphyry Belt and hosting several copper-gold porphyry deposits at various development stages. Within this context, ATEX characterizes Valeriano as a large copper-gold porphyry system with both porphyry-hosted and breccia-hosted mineralization.

ATEX’s disclosures also reference ongoing work to advance the project beyond pure resource delineation, including baseline environmental studies, monitoring, hydrogeology and geotechnical scopes, and permitting activities related to future drill campaigns. These activities are described as part of a broader effort to advance and de-risk the Valeriano Project.

Corporate and Capital Markets Activity

Company news indicates that ATEX is listed on the TSX Venture Exchange under the symbol ATX, and that ECRTF represents trading in another market. ATEX has reported:

  • Exercises of common share purchase warrants, with proceeds described as strengthening the company’s balance sheet.
  • Grants of restricted share units (RSUs) and stock options to employees, officers, and directors under its equity incentive plans.
  • Ongoing engagement of an investor relations service provider to assist with investor relations strategy, corporate content, public reporting, and shareholder engagement.
  • Annual general and special meetings where shareholders vote on matters such as the number of directors, election of directors, appointment of auditors, and approval of stock option and restricted share unit plans.

These disclosures illustrate that ATEX combines technical exploration work at Valeriano with corporate governance processes typical of a publicly traded exploration-stage company.

Key Technical Themes in Disclosures

Across its news releases, ATEX highlights several recurring technical themes at Valeriano:

  • High-grade breccia mineralization (B2B Zone), with reported copper equivalent grades over significant intervals and indications of vertical and lateral continuity.
  • High-grade porphyry trend within the broader Valeriano Porphyry system, with long mineralized intervals and step-outs that extend the trend along strike.
  • Use of copper equivalent (CuEq) calculations based on specified metal prices and metallurgical recoveries, with multiple CuEq reporting bases (in situ, MRE recoveries, and metallurgical test-work recoveries) described in detail.
  • Application of NI 43-101 standards, including identification of a Qualified Person responsible for reviewing and approving scientific and technical information.

Investors researching ECRTF as a way to follow ATEX Resources Inc. are therefore primarily gaining exposure to an exploration-stage copper-gold porphyry and breccia system in Chile, with company communications focused on drill results, geological interpretation, and incremental de-risking of the Valeriano Project.
