Nexa Resources and EnviCore Team Up to Create Cementitious Materials from Tailings


Lima, Peru and Calgary, CanadaNexa Resources (NYSE:NEXA) (“Nexa”), a leading global mining company, and EnviCore Inc. (“EnviCore”), an innovative environmental solutions provider, are pleased to announce their strategic collaboration to repurpose mining tailings into high-quality cementitious materials. This groundbreaking partnership represents a major advancement in sustainability within the mining sector.

By combining Nexa's extensive mining expertise with EnviCore's cutting-edge technological solutions, the collaboration aims to address one of the mining industry's most critical environmental challenges: the responsible management and utilization of mining tailings. These tailings, which are by-products of mining operations, will be transformed into cementitious materials, offering a sustainable alternative to traditional cement usage. Preliminary testing conducted by a Peruvian cement company has shown that replacing up to 30% of cement with tailings-cementitious material in a mortar mix demonstrated similar strength to a control cement sample.

After the successful validation of EnviCore’s technology by a third-party cement company, Nexa and EnviCore signed an MOU last year to deploy the technology at scale. This validation marks a paradigm shift in the mining industry, highlighting a shared commitment to environmental stewardship and the development of sustainable solutions. Through the implementation of advanced technologies and extensive research, this collaboration aims to reduce the environmental impact associated with mining activities while promoting a circular economy model.

Both Nexa and EnviCore are dedicated to fostering a circular economy by embracing innovative approaches that go beyond mere compliance with environmental regulations. This partnership represents a shared vision for sustainable mining practices that prioritize environmental responsibility while generating positive social and economic benefits.

"Partnering with Nexa Resources to repurpose mining tailings perfectly aligns with our mission to provide innovative and sustainable minerals repurposing solutions”, said Shahrukh Shamim, CEO and Co-Founder of EnviCore. "Together, we are demonstrating that responsible mining practices and environmental stewardship can coexist, paving the way for a more sustainable future."

Caio Moreira Van Deursen, Innovation manager at Nexa Resources said, "We are excited to embark on this transformative collaboration with EnviCore. By repurposing mining tailings into cementitious materials, we are taking a significant step towards our sustainability goals, contributing to a greener future for the mining industry."
