ADVENTUS MINING AND SALAZAR RESOURCES ACHIEVE KEY MILESTONE IN THE PUBLIC CONSULTATION PROCESS FOR ENVIRONMENTAL LICENSING OF EL DOMO - CURIPAMBA PROJECT

Adventus Mining Corp. and Salazar Resources Ltd. have provided an update on the advancing environmental licensing and community training activities for the El Domo/Curipamba copper-gold project, located in central Ecuador.

El Domo's first phase of official public consultations successfully completed

The participants have successfully completed the first of two phases of environmental and social impact assessment (ESIA) consultation activities for the El Domo project, which was managed and overseen by the government of Ecuador. The ESIA consultation process follows the technical approval of the El Domo ESIA in May, 2022 (see news release dated May 31, 2022), and is in compliance with the new environmental consultation regulation decree that was signed by the President of Ecuador in 2023 (see news release dated June 1, 2023). This official information phase of the consultation process is the culmination of many months of planning by the government ministry of environment (MAATE -- Ministerio del Ambiente, Agua y Transicion Ecologica). The information mechanisms included four information centres that were installed for 14 days in the canton of Las Naves, informative videos published on the MAATE website, five additional workshops in the local communities, and four open houses (assemblies) in the direct and indirect areas of influence of the project. Many local residents participated in the process over the 14-day period, with strong participation and engagement from different communities.

The completion of this phase represents the midway point for the final stage in the ESIA approval process, which started in June, 2023. The next step is for MAATE to issue a public summary report, which is expected to be released in August, 2023, followed by a final phase of consultation activities. The participants continue to expect approval of the environmental licence from the government of Ecuador in the second half of 2023. Subject to this approval and final financing arrangements, El Domo construction activities are also expected to start in the second half of 2023 (see news release dated July 14, 2023).

Ramp-up of training and development programs at El Domo

As part of El Domo's continued commitment to local training and employment, the participants have started the second round of heavy equipment operator training in the town of Las Naves. The program is being implemented in partnership with Stracon SA -- a mining contractor with extensive experience in Latin America, Ripconciv -- a large Ecuadorean infrastructure construction contractor -- and a university in Ecuador -- the Universidad Tecnica Particular de Loja (UTPL) (see news release dated Nov. 17, 2022).

This round of operator training includes 54 participants, of which 15 per cent are women. All participants are from the local communities in the direct and indirect areas of influence of the El Domo project. The scope of the program includes training on simulators and hands-on training on heavy equipment. The certified program enables operator trainees the opportunity to obtain their professional licences for operating the heavy equipment. Subject to the environmental licensing approval, an additional round of approximately 70 participants are expected to complete the operator training program by early 2024.

This heavy equipment operating training program follows the successful completion of the heavy equipment maintenance training and trades training program that ended earlier in 2023 (see news release dated Feb. 13, 2023). The completed operator maintenance training program and the trades training program included an enrolment rate of 25 per cent and 40 per cent women, respectively.
