ESGold Corp. (CSE: ESAU) (OTCQB: ESAUF) announced it has signed a non-binding memorandum of understanding (MOU) with Québec-based Culture H. Dolbec Inc. to evaluate the potential supply and beneficial reuse of up to 300,000 metric tonnes annually of neutralized mining residue from its fully permitted Montauban Gold-Silver Project in Québec. The agreement could create an additional revenue stream alongside ESGold’s planned gold and silver recovery operations, according to the press release disseminated on behalf of ESGold (CSE: ESAU) (OTCQB: ESAUF).
Under the MOU, the companies will assess the use of treated mining residue as aggregate for potential construction applications. Any definitive agreement and deliveries will depend on material characterization, environmental testing, and applicable regulatory approvals. No pricing or minimum purchase commitments have been established. The initiative supports ESGold’s strategy to recover precious metals from historic mine tailings while addressing environmental risks associated with more than a century of mining activity in the Montauban region. The company’s planned closed-circuit processing system is designed to recover remaining gold and silver while treating, neutralizing, and stabilizing residual material for potential reuse.
“Our goal is to turn what has been an environmental liability for more than a century into something that benefits both the community and our shareholders,” said ESGold CEO and Director Gordon Robb.
The news matters because it signals a potential shift in how mining companies manage legacy waste. By exploring the reuse of neutralized residue as construction aggregate, ESGold aims to reduce environmental risks and generate additional revenue from material that would otherwise require long-term management. If successful, the model could serve as a template for other mining projects seeking to combine resource recovery with waste reduction. However, the non-binding nature of the MOU and the absence of pricing or volume commitments mean that significant uncertainty remains until testing and regulatory steps are completed.
For readers tracking the ESG sector, the announcement highlights growing interest in circular economy approaches within mining. ESGold’s fully permitted, fully funded, pre-production status and its flagship Montauban project under construction position the company to potentially advance this initiative alongside its core gold and silver recovery plans.
