King Copper Discovery Stock Price, News & Analysis

King Copper Discovery Corp. (TBXXF), formerly known as Turmalina Metals Corp., is a TSX Venture Exchange (TSXV)–listed mineral exploration company. The company is focused on advancing the Colquemayo copper-gold-silver project in southern Peru and is also quoted on the OTCQB under the symbol TBXXF and on the Frankfurt Stock Exchange under 3RI. According to multiple company news releases, King Copper is led by a team that has been responsible for multiple gold-copper-silver discoveries in South America.

The company’s primary asset is the Colquemayo Project, an epithermal and porphyry copper-silver-gold exploration project located in the General Sanchez Cerro province in the Moquegua department, near the border with the Arequipa department in southern Peru. Company disclosures describe Colquemayo as a road-accessible project where King Copper, through a wholly owned Peruvian subsidiary, holds an option to acquire 100% of nine mining concessions from Compañia de Minas Buenaventura S.A.A. The property covers approximately 6,600 hectares and hosts multiple epithermal and porphyry targets.

Colquemayo project characteristics

According to the company’s news releases, Colquemayo lies within a late Miocene to Pliocene epithermal belt and exhibits features typical of high-sulphidation epithermal systems. Historic work by previous operators, including Rio Tinto and Buenaventura, comprised roughly 27,000 metres of diamond drilling across about 80 holes, detailed geological mapping, extensive surface geochemistry with thousands of rock chip and channel samples, high-resolution topography, and geophysical surveys (magnetometry, chargeability and resistivity) over key hydrothermal centres.

Alteration mapping reported by the company shows zonation characteristic of high-sulphidation epithermal mineralization, including argillic alteration with kaolinite and dickite, advanced argillic alteration with quartz and alunite, deeper pyrophyllite zones, and zones of massive and vuggy silica. Several phreatomagmatic and hydrothermal breccias with significant gold and copper values have been identified. The company highlights several kilometre-scale hydrothermal targets at Colquemayo, including the Amata, Cairani, Coripuquio and Yanarico areas.

Historic drill results disclosed in company releases illustrate the high-grade potential of the system. At the Amata area, reported intercepts include long intervals of copper mineralization with associated gold and silver, such as hundreds of metres grading copper with internal higher-grade zones. Additional intercepts at Amata and other centres such as Cairani and Coripuquio show combinations of copper, gold and silver over tens to hundreds of metres. These results form the basis of King Copper’s exploration model at Colquemayo.

Exploration strategy and technical work

King Copper’s exploration approach at Colquemayo, as described in its news releases, is based on integrating historic drill core, assay data, mapped geology, alteration zoning and geophysical information to build detailed geological models. The company has received and re-logged approximately 15,000–20,000 metres of historic drill core from prior drilling campaigns. This re-logging work is being used to validate previous interpretations, determine the geometry of breccia bodies, and refine drill targets.

The company notes that its exploration model at Colquemayo draws on similarities to linked epithermal and porphyry systems in the Andes, and explicitly references Filo del Sol in Argentina as an example. In addition to following up high-grade epithermal copper mineralization identified in earlier drilling, King Copper’s technical team is also assessing indications of an underlying copper porphyry system at depth.

Beyond the three main hydrothermal centres that have been drill tested to date, King Copper reports that exploration will also focus on areas of argillic and advanced argillic alteration that may represent less eroded parts of epithermal systems. These areas could host new hydrothermal centres for initial drilling, and the company has indicated that additional geophysical coverage of the remaining parts of the property is under consideration.

Permitting, environmental and community relations

Company updates describe a structured approach to permitting and environmental baseline work at Colquemayo. King Copper (and previously Turmalina Metals) has engaged INSIDEO, an environmental consulting firm based in Lima, to complete baseline studies and prepare an environmental impact assessment known as the Declaración de Impacto Ambiental (DIA), which is a key requirement for the drill permit application in Peru.

INSIDEO’s work, as reported by the company, has included soil and water sampling, air quality and noise control measurements, and biological baseline studies. These activities are intended to establish an environmental baseline for the project area. The company has stated that access agreements with the local communities of Palcamayo and Amata, who own most of the surface rights over the project, have been finalized to allow initial fieldwork. King Copper also reports maintaining contact with neighbouring communities and local authorities to inform them about the nature and status of the project.

Corporate evolution and capital markets

According to its news releases, the company previously operated as Turmalina Metals Corp. under the TSXV symbol TBX and OTCQX symbol TBXXF. A corporate name change to King Copper Discovery Corp. and a TSXV symbol change to KCP became effective on March 11, 2025, while the share capital remained unchanged. The company’s over-the-counter symbol TBXXF continues to reference this issuer for U.S. investors.

King Copper is described as a TSXV-listed exploration company with a focus on South American gold-copper-silver projects. News releases state that the company has completed non-brokered private placement financings to fund exploration and working capital, including offerings of common shares. Proceeds from these financings are earmarked for advancing exploration at Colquemayo, including diamond drilling, as well as for general corporate purposes. Certain financings have included participation by insiders and strategic investors, subject to applicable securities regulations.

Technical and leadership team

King Copper emphasizes the depth of its technical and leadership team in its public communications. The company notes that it is led by individuals responsible for multiple gold-copper-silver discoveries. Its technical team includes roles such as Vice President Exploration and Corporate Development and Lead Strategic and Technical Advisor, with experience in discovering and advancing mineral deposits globally.

Recent announcements highlight the appointment of senior technical consultants with decades of exploration and operations experience in Latin America, including expertise across the mining cycle from exploration and feasibility studies to construction and operations. These individuals bring backgrounds in sustainability, environmental management, geology, geochemistry and metallogenesis, and have worked for both major and junior mining companies. The company also reports appointments to its board of directors with experience in mining finance, capital markets, mergers and acquisitions, governance and regulatory compliance.

Project portfolio and regional focus

While the company’s current branding and communications emphasize the Colquemayo copper-gold-silver project as its flagship asset, earlier disclosures under the Turmalina Metals name describe a broader portfolio of high-grade gold-copper-silver projects in South America. These projects are characterized in company materials as having high-grade mineralization on established mining licenses and presenting drill targets. Prior disclosures also identify the San Francisco project in San Juan, Argentina as a principal project, with the company considering alternatives such as joint ventures to monetize or advance that asset.

Overall, King Copper Discovery Corp. presents itself, through its news releases, as a South America–focused mineral exploration company concentrating on copper, gold and silver systems. Its main current focus is on advancing the Colquemayo Project in Peru through geological modelling, environmental permitting, community engagement and planned drilling, supported by capital raised in private placements and guided by an experienced technical and corporate team.
