Key Terms

circular economy, tailings, molybdenum, emissions, +2 more

6 terms

circular economy technical

"a leading recognition in Chile for circular economy practices"

A circular economy is a way of designing and using products so that materials are reused, repaired, or recycled rather than discarded as waste. It mimics natural systems where resources are continually reused, reducing environmental impact and conserving resources. For investors, it represents an opportunity to support sustainable businesses that focus on efficiency and long-term resource management.

tailings technical

"copper and molybdenum recovery from tailings, energy efficiency"

Tailings are the leftover rock, water and fine particles produced when ore is crushed and processed to extract metals or minerals. Think of them as the muddy residue from a kitchen filtering process: they are stored in ponds or engineered dams and can carry chemical contaminants, so they matter to investors because they represent ongoing cleanup costs, regulatory liabilities and operational risks that can affect a mining company’s finances and reputation.

molybdenum technical

"copper and molybdenum recovery from tailings, energy efficiency"

Molybdenum is a metallic element used in small amounts to strengthen steel and other metals, improve heat resistance, and act as a component in catalysts and high-tech parts. Think of it like a special seasoning added to metal to make it tougher and last longer. Investors track molybdenum because its supply, production costs, and demand from construction, energy and industrial sectors can affect mining companies’ revenues and the prices of related raw materials.

emissions technical

"reduces energy consumption, emissions and the use of natural resources"

Emissions are pollutants or greenhouse gases released into the air, water or soil from activities like factories, vehicles, power plants and industrial processes — imagine a factory breathing out smoke or a car’s tailpipe. For investors, emissions matter because they drive regulatory rules, cleanup costs, fines and shifts in customer demand; a company with high emissions can face higher expenses, legal risks and damage to its reputation, all of which can affect profits and share value.

traceability technical

"energy governance based on indicators and traceability"

Traceability is the ability to follow a product, component, or piece of data backward and forward through every step of its lifecycle, like reading a parcel’s tracking history to see where it came from and where it went. For investors, strong traceability lowers risk by making recalls, quality problems, and regulatory breaches easier and cheaper to manage, while boosting consumer trust, supply-chain efficiency, and the reliability of reported information.

decarbonization technical

"contribution to industrial decarbonization"

Decarbonization is the process of cutting a company’s greenhouse gas emissions across its operations, supply chain and products by switching to cleaner energy, improving efficiency and changing materials or processes. For investors it matters because lower emissions can reduce regulatory and energy costs, limit legal and reputational risks, and signal long-term competitiveness—like a business replacing a gas-guzzling fleet with fuel-efficient or electric vehicles to save money and stay compliant.

VANCOUVER, British Columbia, Dec. 02, 2025 (GLOBE NEWSWIRE) -- Amerigo Resources Ltd. (TSX: ARG; OTCQX: ARREF) (“Amerigo” or the “Company”) is proud to announce that Minera Valle Central (“MVC”), the Company’s 100% owned operation located near Rancagua, Chile, has been awarded the 2025 Circular Awards in the Energy Challenge category, a leading recognition in Chile for circular economy practices. This prestigious award highlights organizations that show measurable impact in sustainability, innovation and leadership.

“This award is a testament to the dedication and ingenuity of our team at MVC. Circularity is at the heart of our business model, and our recognition at a national level reinforces the importance of what we do—not just for our company, but for the communities and environment we serve. We are proud to lead by example and will continue to innovate for a more sustainable future”, said Aurora Davidson, Amerigo’s President and CEO.

MVC received this award for its Energy and Environmental Liabilities Transformation project. This project integrates three strategic dimensions: copper and molybdenum recovery from tailings, energy efficiency in production processes and systematic application of circular economy principles. By recovering additional copper from the fresh and historic tailings generated by Codelco’s El Teniente mine, MVC converts an environmental liability into a valuable asset. The use of these tailings as a production input reduces energy consumption, emissions and the use of natural resources. The project incorporates state-of-the-art technology, continuous operational optimizations and robust energy governance based on indicators and traceability.

The Circular Awards, created by Fundación Desafío Circular, are the leading national recognition for circular economy initiatives in Chile. Winners are selected by a panel of 25 sustainability experts who evaluate projects in various thematic categories. In 2025, MVC was chosen as the winner in the Energy Challenge category, which highlights projects with notable advances in energy efficiency, emissions reduction, smart energy use and contribution to industrial decarbonization.

Amerigo congratulates the entire MVC team on this outstanding achievement and thanks the Circular Awards organizers for promoting sustainability and circular-economy practices across Chile.
