Within the mining plans, there is a mineralized zone with 1,016 KTon of mineral resources (Mariela 4, Doña María Piso 6, and Melisa 3) with average grades of 10.8% Zn and 2.6% Pb, for which a mining method had not yet been defined. The RMR of the mineralized zone of the Melisa 3 orebody is in the range of 20-40, which complicates mining with the traditional methods used at the mine (Cut and Fill, Sublevel Stoping), since it requires sacrificing good ore pillars to maintain stope stability. In some cases, stability simulations did not ensure the optimal safety factors for the safe mining of this zone. Given the mining difficulties in the Melisa 3 zone, a review was initiated of the experiences with the application of the Sublevel Caving (SLC) method. This mining method is not commonly used in Peru; therefore, evaluations were conducted regarding stability, ore recovery, potential surface subsidence, and ore extraction rates, in order to
