en.Wedoany.com Reported - Following a detailed technical analysis, Peru's National Environmental Certification Service (Senace) approved the "Third Technical Support Report for the Iscaycruz Mining Unit (Unidad Minera Iscaycruz)" submitted by Empresa Minera Los Quenuales, authorizing operational improvements at the mining unit. The approval was formalized through Director's Resolution No. 00090-2026-SENACE-PE/DEAR, granting environmental feasibility after confirming that the proposed modifications comply with relevant technical, environmental, and regulatory standards.

The approved improvements primarily include the expansion of the Tinyag Inferior tailings dam. The project will be implemented in three phases, planning to increase storage capacity by 2,148,765 cubic meters, equivalent to a 60.7% increase, helping to extend the facility's operational life. Additionally, the mining unit will relocate the southern entrance, as components in the Genoicocha-Escondida area will lose access after the tailings dam expansion. The new entrance will be 1,124 meters long, 6 meters wide, with a maximum slope of 10%. The road will be constructed from mine waste rock, with excess material placed in the Tinyag waste dump as part of closure and physical stability measures.

Peru's National Environmental Certification Service considers that the proposed actions will generate insignificant environmental impacts. Accordingly, environmental management measures have been established to prevent, control, and mitigate these impacts, in compliance with commitments outlined in the approved environmental management instruments. The mining unit is located in the Pachangara district, Oyón province, Lima region.
