Don Turvey, CEO and Director of Cornish Metals, stated: “We are very pleased to share our inaugural sustainability rating from Digbee, which demonstrates the Company’s commitment to operating to international best practices and acting with transparency. We enjoyed working with Digbee on this and appreciate the comprehensive overview that they have compiled. We understand there is always room for improvement, and we will be taking Digbee’s points of feedback onboard as we continue to develop our environmental, social and governance practices.”

Jamie Strauss, founder and CEO of Digbee, commented: “The successful completion of the Digbee sustainability assessment underscores Cornish Metals’ belief that responsible mining is not only the right approach, but a critical differentiator. By embedding responsibility at the heart of its strategy, the company strengthens its social licence to operate and builds trust among all stakeholders - from communities, regulators and investors.

Earning an excellent ‘A’ rating through the Digbee assessment demonstrates the company’s significant achievements to date in transparency, environmental stewardship, and community engagement. This independent verification not only validates Cornish Metals’ current performance but also reflects its clear vision for continuous improvement - proving that mining can be both a driver of economic opportunity and a trusted partner in protecting and enhancing the communities and environments in which it operates.”
