Calibre Mining receives environmental permit for Pavon Central

Global Mining Review,

Calibre Mining Corp. has been granted the key environmental permit for development and production of the Pavon Central opencast mine from the Ministry of the Environment and Natural Resources in Nicaragua.

Darren Hall, CEO of Calibre, stated: “The approval of Pavon Central marks a significant milestone in the company’s efforts to organically grow production, utilising a portion of the installed excess capacity at our Libertad mill. We are excited to introduce Pavon Central into the development profile fuelling grade driven production growth in 2023 and 2024 from the 6.49 g/t gold (Au) reserve. We will continue to work closely with regulatory authorities, local communities, and all stakeholders to ensure safe and responsible development and mining at Pavon Central.”

During 2021, Calibre initiated mining at Pavon Norte, the first of three known gold deposits hosting mineral resources in the district. Calibre is advancing development of Pavon Central with the objective to commence production in 1Q23. Combined 2021 end-of-year mineral reserves for the Pavon Norte and Central opencast mines total 165 000 oz at an average gold grade of 5.07 g/t. Pavon Central hosts an average reserve grade of 6.49 g/t Au, notably higher than the average 3.28 g/t Au grade at Pavon Norte and is expected to contribute to the company’s 2023 and 2024 production growth.

Pavon Central drill highlights

  • PVC-21-046: 5.08 g/t Au over 7.6 m estimated true width (ETW) from 72.7 m.
  • PVC-21-062: 4.21 g/t Au over 6.5 m ETW from 32 m.
  • PVC-21-078: 4.46 g/t Au over 9.8 m ETW from 94.6 m.
  • PVC-21-081: 8.58 g/t Au over 4 m ETW from 145.3 m.

Pavon South drill highlights

  • PVS-21-004: 11.56 g/t Au over 12.4 m ETW from 37.6 m.
  • PVS-21-002: 4.08 g/t Au over 2.3 m ETW from 49.4 m.
  • PVS-21-006: 3.04 g/t Au over 28.4 m ETW from 26.2 m.
  • PVS-21-014: 11.75 g/t Au over 3.9 m ETW from 81.2 m.

Calibre has identified the potential for resource expansion along strike and at depth at the Pavon vein system and at new vein targets within the overall 32 km2 land package, where two rigs are currently operating.

Since the beginning of 2021, Calibre has continued to progress development at Pavon Central, working closely with its environmental consultant and the ‘Centre for an Understanding with Nature’ in Nicaragua, to ensure quality engineering designs with minimal impact to the environment. Calibre has advanced engineering studies, mine plans, road construction designs, and socio-environmental initiatives focusing on community resilience, water conservation, and sustainable forestry and ranching. With road construction to the project underway, Calibre is well-positioned to commence production from Pavon Central in 1Q23.

Alan Bolt, Director General of the Centre for an Understanding with Nature (CEN), stated: “Having been approved by the population through public consultation and confirmed by the Ministry of the Environment, execution of Pavon Central will allow the local communities, CEN and Calibre to continue working together on the strengthening of native bee populations, forest and water restoration, and socioeconomic initiatives such as women's entrepreneurship and healthier homes with smokeless stoves and access to clean water. Calibre’s continued presence enables us to improve the local economy, contributing to a life without violence or poverty, and generating the necessary resilience to successfully face climate change.”
