Project | Aranzazu
Location | Zacatecas
Project description: In this project we carry out several activities, such as the development of ramps, levels, against fronts, to have access to the mineralized area, with face drilling equipment; We prepare the chambers to the appropriate dimensions for the exploitation stage (overflows, exit shaft) which are drilled with long drilling equipment from level to level, after extraction we proceed to fill the chambers, as well as the ore hauling and tepetate of all activities as mentioned above.
Services: Development and production.

Project | Mercedes
Location | Sonora
Project description: The project is comprised of four areas: Diluvio, Lupita, Rey de Oro and Mariana; The company is in these areas developing production levels and tumbling for mineral extraction. The objective of the project for Cominvi is to deepen through ramps and accesses the preparation of new places that make the mine viable and through them reach to the ore block for production continuity.
Services: Development.

Project | Tall Pines
Location | Chihuahua
Operations began in area II (Dolores ramp) with the preparation of three of its main ramps with a section of 4.3 meters. X 4 meters In the same way, preparation and infrastructure works were carried out in areas I and III (San Nicolás and Villalpando, respectively), referring mainly to service ramps, crossings, accesses, fronts with a section of 3.0 meters. X 3.0 mts., as well as conventional 1.5 mts. X 1.5 meters. The equipment we used for these developments were: an electrohydraulic jumbo, leg machines, a 6 yd3 scoop tram, two 3 yd3 and 2 2 yd3.

Project | Half Moon
Location | Guerrero
Project description: The breaking of two entry ways will be carried out, for the development of internal ramps, sublevels, fronts and against fronts necessary for the exploitation stage that is planned to be carried out in 2024, in addition to the necessary preparation tasks such as electrical substations, sump pumps, ventilation crosses, vertical development with specialized equipment for emergency exits, ventilation circuits.
Services: Development.

Project | Las Chispas
Location | Hermosillo
Project description: In this project we are dedicated to the development and preparation of tasks, in which sections of Ramps are developed to give access to ore areas, in the same way secondary tasks are given as counterfronts to reach levels of preparation and extraction of the tomb.
Our development program for the year 2021 was 550 linear meters per month, but due to the need to prepare new areas and reach the ore tasks, it was increased to 757 meters per month on average; Currently, ore structures have been cut and the levels of preparation of the tomb have begun, by 2022 it is intended to start production.
On the other hand, the ventilation circuits have been started by means of counterwells made with a leg machine and long drilling equipment, which will help us to have better ventilation for the extension of tasks and their deepening.
Services: Development and preparation.
Project | Mercedes
Location | Sonora
The start of operations in August 2010, a contract for 21,000 meters of worked land for the period 2010 - 2012 began. With electro-hydraulic drilling equipment with one and two arms, with the support of 6 yd front loaders and trucks of 14 m we have produced around 80,000 tons of ore from the start-up period of its new processing plant. We have carried out the reinforcement of the task with a jumbo anchor and the placement of concrete with a robot.

Project | Palmajero
Location | Chihuahua
In this company we developed the general ramp of the 5.5 m section. X 4.6 meters. Generation of compressed air and electricity for services, the total length of the ramp was 2,500 meters. In addition to crossings of the same section every 30 meters. vertical to cut the ore body. Development of 150-meter alimak counterwheels. for emergency road and services.
Project | Bolañitos
Location | Guanajuato
In this mine we participated in the preparation of the Daniela ramp, access crossings for the development of the sublevels. Also in this project, we developed service and ventilation raises at the ends of the ramp using the conventional method and rapid raises by means of long drilling.
Project | Ocampo
Location | Chihuahua
In this company we develop the continuity of the main structures such as Aventurero, Juliana and Mastuerzo with a total of 10,250 meters. of developments for which a qualified team members and an installed infrastructure of equipment and machinery were deployed. The main equipment consisted of electro-hydraulic drilling equipment, loaders of various capacities, hauling equipment with low-profile and highway mining trucks, as well as facilities such as workshops, offices, warehouses and camps.
Jumbo is the name given to an electro-hydraulic equipment equipped with one or several hydraulic hammers (drills) on hydraulic arms that allow access to any part of the face. It is a machine designed to carry out underground work quickly and automatically: advancement of tunnels and galleries, cross drilling, benching with horizontal holes and mining by cut and fill, among others.
