The Alpamarca unit began operations in April 2014 and is comprised of the Río Pallanga underground mine (suspanded since 2015), Alpamarca open pit, Alpamarca concentrator plant and Romina expansion project.
Alpamarca open pit production is projected until December 2023 and the plant will be fed with the old piles and tailings stock.
A feasibility study of the Romina project was concluded in 2022. Project is expected to have the EIA approved in 2023 so that the start of the detailed engineering, construction and commissioning of the project can be planned with the aim of starting production operation in the first quarter of 2025. |

Summary:
The Alpamarca operations is made up of the Río Pallanga underground mine (suspended), the Alpamarca open pit and the Romina expansion project.
The Alpamarca-Rio Pallanga project is a deposit of lead, zinc, silver and copper veins. It is located 4,700 meters above sea level in the Santa Bárbara district of Carhuacayan, Yauli Province, Junin Region.
Ten kilometers from Alpamarca is the old Rio Pallanga mine, a deposit with significant potential at depth and in the lateral extensions of the vein in the explored area. The Rio Pallanga resources, which contain high grades of silver, will support ongoing operations at Alpamarca and provide a solid basis for development of projects at Colquihuarmi and Carhuacayan, located 14 and 25 kilometers to the southwest, respectively.
Romina II
The Puagjanca and Andrea deposits are in an advanced exploration project stage, with polymetallic mineralisation of zinc, lead, and silver. The mineralisation is in the form of lead and zinc-rich replacement bodies and mantles. It is located 15 km west of the Alpamarca mine in the Pacaraos district, Huaral province. In 2022 a drilling campaign refined the deposit extents, resulting in a reduction of 2.5Mt and a gain in mineral resource grades.
Summary:
(Translated from Spanish by Google Translate)
The Alpamarca operating unit is located in the Santa Bárbara district of Carhuacayán, Yauli province and Junín department, 182 km east of Lima.
This unit began operations in April 2014 and is made up of the Río Pallanga underground mine (suspended), Alpamarca open pit, Alpamarca concentrator plant and Romina expansion project.
At Río Pallanga mining activities suspended since 2015. Operations were carried out within the Pallanga 3 concession and continued with preparation, development and production of the Ramal 1 and San José veins. Long-hole drilling was used in narrow veins, where very good results were obtained in controlling mining widths.
The Alpamarca deposit is mechanically-operated open pit. This pit is being operated in two sectors: Sector 1, which consists of the Nito pit and Sector 2, which consists of the Juanita, Fortuna Anita and Don Pablo pits.
During the year 2022, at Alpamarca open pit, interramp slope angles have been improved, between 3° and 6°, allowing a reduction of sterile and improving the recovery of the mineral.
According to the update of reserves as of December 2022, the exploitation of the Alpamarca pit is projected until December 2023 and the plant will be fed with ore from stockpiles and old tailings.
