Mine Life22 years (as of Jan 1, 2021)
While mining operations were placed on care and maintenance in 2019, Lagunas Norte’s gold recovery plant has continued to produce gold from leach pad ore and Boroo expects to recover approximately in excess of 100koz of gold inventory by 2023.

The next phase of the mine will be to recover gold from carbonaceous oxide ore through the Carbonaceous Material Oxides Project (“CMOP”) and sulphide ore through the Refractory Material Project (“PMR”).

The CMOP project is designed to process about 15.0 million tonnes of high-grade gold bearing oxides mined early in the life of Lagunas Norte property.

Deposit Type

  • Epithermal
  • Vein / narrow vein


Summary:

Lagunas Norte differs from many other large high- sulphidation epithermal gold deposits of the Andes in that a majority of the known resource is contained within Cretaceous siliciclastic sedimentary rocks, and a relatively small portion is within the Tertiary volcanic sequence that is the primary host elsewhere (e.g., Yanacocha, Pierina). The main host rock sequence at Lagunas Norte consists of quartz sandstones and subordinate interlayered mudstone, siltstone, and carbon-rich siltstone, correlated with the Lower Cretaceous Chimú Formation (Lewis, 2002).

The Lagunas Norte mineralization occurs in the southeast portion of the Alto Chicama property. The mineralization is finely disseminated and is hosted mostly by siliclastic sedimentary strata.

The mineralization within the present pit extends for approximately two kilometres in the north-northwest direction by approximately two kilometres in the east-northeast direction and for more than 200 m vertically.

Mineralization is the result of multiple volcanic and hydrothermal events. It is hosted in both the Tertiary volcanics of the Calipuy Group and the underlying Cretaceous sedimentary rocks of the Chimú Formation. The alteration associated with the mineralization is typical of a highsulphidation epithermal environment, characterized by silica (SiO 2 ), surrounded by alunite [KAl3(SO4)2(OH)6], dickite [Al2Si2O5(OH)4] and pyrophyllite [Al2Si4O10(OH)2]. Trace elements typically associated with th ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The Lagunas Norte Mine is a traditional open pit truck/shovel heap leach operation that has been in continuous production since 2005.

Open pit mining operations are located on a mountain top with gentle to extreme terrain between elevations of 3,800 MASL and 4,200 MASL.

The Lagunas Norte ultimate pit measures approximately 2.5 km along strike, typically 0.8 km to 1.2 km across with a surface footprint of approximately 240 ha, and has a maximum depth of approximately 250 m. There are four main areas of development identified within the ultimate pit: Dafne, Josefa, Alexa, and the moraines furthest to the north. The open pit is overlooked by the Shulcahuanca Dome, a sacred feature, and there is an approximate 50 m standoff from the base of the Shulcahuanca Dome for mine planning and operations.

Final arrangement of the Lagunas Norte waste rock facilities is for the continued development of surface dumps surrounding the Lagunas Norte ultimate pit other than to the south-southeast where the HLF is located, resulting in a relatively compact overall footprint.
