contribution lies in the ability to selectively separate the fraction with higher metal content before it is sent to the plant, significantly reducing the volume of inert material entering the process. Among its most relevant characteristics are: ● Mass balance optimization, increased feed grade, ● Recovery of economic value from low-grade ranges previously classified as waste, ● Generation of a lower operational cut-off grade, ● Potential extension of life-of- mine (LOM) by incorporating marginal material as economically viable ore. In this way, ore sorting enables a structural transformation in the resource-toreserve conversion process. By lowering the economic cut-off grade, it unlocks blocks that under the traditional methodology would fall outside the pit or be classified as waste; by concentrating the ore at an early stage, it increases overall system recovery; and by reducing downstream unit costs, it allows the economic value of the deposit to be redefined. Taken together, these improvements address the limitations of the conventional approach and enable a more efficient, selective, and sustainable strategy for the management and valuation of mineral resources.

METHODOLOGY 5.1 Ore Sorting Parameters XRT technology shows high compatibility with various mineralization, demonstrated by its efficient application in sorting operations for copper, zinc, silver, and molybdenum, achieving homogeneous upgrade ratios for copper, zinc, and silver, lower values for molybdenum, and high ore sorting recovery factors for zinc and silver.
