FAQ

• How much is the projected investment in Loma Larga?

  According to the Investment Agreement signed with the Ecuadorian State, DPM Ecuador will invest a total of USD 419,000,000 in the country.

• How many jobs will be generated with the construction of the mine and how many will be for the locality?

  Employment contracts will be divided into two phases:

  • Construction of the Mine: At this stage, up to 1,500 direct employment positions will be hired at its peak.
  • Mine operation: During this phase, 500 direct employment positions will be generated.

  80% of the hires will be local.

• How is DPM Ecuador's relationship with the community?

  Since 2021, a robust Corporate Social Responsibility (CSR) program has been implemented in Ecuador, collaborating with parish Governments (GADs) to promote community development in areas such as health, infrastructure, culture, education, and production. In addition, 100% of the community in the area of direct social influence has been informed about the development of the Loma Larga Mining Project.

• What are the benefits for the community near the LLMP?

  DPM Ecuador is investing in the social advocacy communities of Loma Larga, focusing on five key areas: health, infrastructure, culture, education and production. These investments are made in coordination with authorities and community leaders, following local Land Use Plans.

  By 2025, investment is focused on strengthening education, culture and sports with initiatives such as:

  • Dundee Sport Team: Provides scholarships to 9 elite athletes and 2 professional soccer teams, Deportivo Cuenca and Ñusta FC, representing Ecuador nationally and internationally.
  • Community Educational Project: Finances studies and training for communities near the Loma Larga Project, supporting university technical careers through an agreement with the American College Institute, basic studies and accelerated high school with FUNDER and technical workshops in bakery, beauty, cooking and hospitality.

  Since July 2025, through our Continuing Education Program (PEC), more than 400 technical certifications in mechanics, welding, construction and electricity have been offered, in collaboration with SECAP and CIMA of the Universidad Técnica Particular de Loja.

• Does the popular consultation in Cuenca affect the development of the Loma Larga Mining Project?

  No. During the development of this process, the Constitutional Court of Ecuador issued an opinion clarifying that the results of the Popular Consultations will have effects only in the future and will not modify previous legal situations. In this context, the Loma Larga mining title, granted in 2001, which authorizes all phases of mining activity (prospecting, exploration, exploitation and closure), remains intact. Since the consultation is not retroactive, it does not affect or limit the rights acquired under that title, in accordance with the principle of legal certainty.

• Was the environmental consultation process developed to obtain the Environmental License for phase change?

  Yes. The Ministry of Environment, Water and Ecological Transition (MAATE), as the competent entity for the development of environmental consultations in strategic projects in Ecuador, carried out the process in accordance with national environmental regulations and current international standards. This process included the participation of the inhabitants of the area of direct social influence of the Loma Larga Mining Project (PMLL), as defined in the Environmental Impact Study. The communities involved were: Cristal Aguarongos Community (Girón Canton), Chumblín Sombrederas Commune (San Fernando Canton) and Duraznos Community (Victoria del Portete Parish, Cuenca).

• Was the Prior Consultation process ruled by the Provincial Court of Azuay developed?

  Yes. In January 2025, the Ministry of Energy and Mines, as the competent entity to carry out the Prior, Free and Informed Consultation in Ecuador, concluded the process in the Community of Escaleras, located in the parishes of Victoria del Portete and Tarqui. This process was carried out in accordance with the comprehensive reparation measures ruled in August 2023 by the Specialized Civil and Commercial Chamber of the Provincial Court of Justice of Azuay.

• Why is it that if Ecuador does not have an organic law to regulate Prior Consultation, the one developed in Loma Larga is valid?

  The enjoyment of the fundamental rights guaranteed by the Constitution of Ecuador cannot be denied due to the lack of issuance of a specific law. In this context, while the legislation on Prior Consultation is being enacted, the process was developed by applying Article 57, paragraph 7 of the Constitution, together with the standards established in Convention 169 of the International Labor Organization (ILO). This ensures that the rights of communities are respected and protected, even in the absence of specific legislation.

• Was the comprehensive reparation measure complied with in which a water report was requested that addresses the sustainability of the Quimsacocha Recreation Area and the Cuenca water recharge area?

  Yes. In October 2024, the Ministry of Environment, Water and Ecological Transition (MAATE) issued a water report on the sustainability of the Quimsacocha Recreation Area and the Cuenca water recharge zone in relation to the Loma Larga Project. The report's conclusions were as follows:

  • The Loma Larga Mining Project (LLMP) does not intersect with the Quimsacocha Recreation Area, so it is sustainable under current conditions and with the future implementation of the project.
  • The LLMP will not influence the Yanuncay, Tomebamba and Machángara rivers, the main sources of drinking water for Cuenca, although a 0.5% reduction in the flow of the Tarqui River is anticipated.
  • The hydrological analysis, together with the water balance and the calculation of the ecological flow, analyzed in the report demonstrates that water-related environmental services are not and will not be affected in terms of human consumption and ecosystem conservation.
• Why were two water reports submitted as part of these remediation measures?

  Although the Ministry of Environment, Water and Ecological Transition (MAATE) was requested to carry out the hydrological report in collaboration with the municipal company ETAPA EP, this was not carried out due to the lack of coordination between the entities.

  Legally, MAATE is the entity responsible for developing and submitting the report to the judicial authority, since it is the only competent authority in terms of the protection, conservation and sustainable use of the environment and natural resources.

• What were the conclusions of the biotic report?

  Given the concern that the Quimsacocha Recreation Area could have undergone changes due to the exploration activities of the Loma Larga Mining Project (PMLL), the report of the Ministry of Environment, Water and Ecological Transition (MAATE) showed that the area is in a good state of conservation, and that its ecosystems maintain their functionality and biodiversity characteristics.

• Will the Loma Larga mining project affect Cuenca's water sources?

  No. Although the deposit is located within the water recharge zone of the Canton of Cuenca, in the upper area of the Victoria del Portete parish, it will not use water from these basins.

  DPM ECUADOR S.A. is authorized to use water from the Crystal Alumbre Gorge that feeds the Jubones Basin with a flow of up to 8 L/s. The project is designed with environmental sensitivity, incorporating advanced technology and engineering solutions based on technical studies. Strict controls will be implemented to minimize environmental impacts, guaranteeing a sustainable operation, without altering or polluting the waters of the Jubones Basin.

• Will the Loma Larga tailings dam be a giant pool at risk of collapse?

  No. The waste generated in the extraction of the Loma Larga deposit will be managed as follows: 50% will be deposited in the tailings dam and the other 50% will be returned to the underground mine after extracting gold, silver and copper. The type of tailings intended for the tailings, known as filtered tailings, will have a humidity of less than 80%. This type of tailings is compact and allows you to create a solid and stable base, similar to that used in road construction. It will not be a liquid deposit.

• Will the tailings dam be toxic and pollute the environment perpetually?

  The remaining waste from mining activity (tailings) will not contain additional elements to those they already possess naturally. Basically, the ore will be repositioned from depth to the surface.

  To avoid changes in their chemical composition due to contact with oxygen and water, they will be encapsulated using geomembranes, which are resistant materials that prevent leakage, as the tailings dam is formed by blocks.

  The tailings dam will be developed gradually over the 12-year life of the mine. At the end, it will become a new formation similar to a hill, whose upper part will be covered with a layer of vegetation and natural soil, capable of hosting flora and fauna.

• Will the Loma Larga Mine pollute the environment with mercury and cyanide?

  The use of chemicals, such as mercury, is prohibited by Ecuadorian law, and is used only for the amalgamation of the metal. In the case of Loma Larga, the material will not be processed in the area or within the country. To separate the gold from the rock with little mineral interest, biodegradable flocculants will be used. This method allows minerals to be separated into spin capsules, similar to how a household washing machine works. The water used in this process can be purified and reused multiple times, similar to water treatment plants that supply water to homes.

• Are Loma Larga and Quimsacocha in the same place?

  No. Although the Loma Larga deposit is located 6 km (on foot) from Quimsacocha, it cannot affect the lagoons for three reasons:

  • Height Difference: The lagoons are 200 meters above the site. By gravity, the water does not rise, so the mine liquid will remain there, much lower.
  • Natural Barrier: Between the lagoons and the site there is an impermeable rock barrier that prevents infiltration. This fact has been demonstrated by extensive studies conducted in the area, both by the company and by local scientists and academics.
  • Containment Design: Loma Larga is designed to contain all liquid that comes into contact with mining operations. All possible scenarios have been considered through engineering and research to avoid any impact on the environment.
