Esmeraldas Mining Services (EMS), is a Colombian company in charge of the exploration and exploitation of the mining titles granted to Puerto Arturo S.A.S. Founded in mid-2009 as Minería Texas Colombia, MTC, we began operations on November 17 of that year when we took control of the Puerto Arturo mine in Muzo, Western Boyaca. Since then, we have been the flagship of The Muzo Companies Colombia in its first decade. In mid-2018, MTC was divided into two companies which are: Esmeraldas Mining Services, EMS, and Colombian Shared Services, CSS.

Currently, we have about a thousand direct employees, mostly inhabitants of the region, making us the largest employer in Western Boyaca. We are also pioneers of inclusion of women in emerald mining within the mining operation on different mining-related tasks. We perform with an underground exploitation that is different from other methods of mining. We use processes that involve high standards combined with traditional techniques of extraction to take care of the stone at all times, reducing the use of explosives and generating a minimum environmental impact.
