"We are very pleased with the response and look forward to continuing to work closely with the community to highlight the benefits Vizcachitas will bring. This includes outdoor recreation projects and the conceptual development of environmental offset that could benefit community properties which have remained underused.

Further information

Securing and maintaining the social licence to operate and enhancing community engagement is a key focus for Los Andes. Work on the ground has continued with the company's community engagement teams focusing on ensuring that the Vizcachitas project remains an engine of sustainable regional development and that meaningful collaboration is occurring with the local stakeholders.

The Vizcachitas project is expected to provide sustainable economic development to the Valparaiso region. The regional GDP is expected to increase by more than 3 per cent with the project's development, according to the social impact assessment study carried out by Jose Ignacio Guzman, professor at Universidad Catolica de Chile (2023).

The company successfully launched the third iteration of its Female Entrepreneurs program. The number of applications increased by 10 per cent year on year to 350 applicants following the success of the previous two programs. Forty-five aspiring businesswomen from across Putaendo county were selected to participate in the program.

Los Andes also renewed and expanded its partnership aimed at developing mining-related skills at local high schools and universities, in collaboration with key national organizations. The partnerships aim to improve young people's access to quality education and training opportunities that prepare them for careers in the modern mining industry.

In 2024, agreements were signed with two communities in Putaendo that own large parcels of land with the aim of working together to advance work on outdoor recreation projects and the conceptual study of environmental offset opportunities for the Vizcachitas project. The company can report that the work has shown potential for collaborative environmental stewardship, and it has renewed the agreements to further advance the opportunities that arose. The collaboration agreement with a local water association in the Putaendo Valley was also renewed.

During the year the company organized a landmark seminar titled "Agriculture and Mining: Collaboration and Synergies of Two Engines of Regional Development," facilitating important discussions on the compatibility and complementary nature of mining and farming activities in the Valparaiso region. The event brought together local farmers, business leaders and the heads of all major national business organizations, including commerce, agriculture, industrial and mining sectors.
