Flotation pilot run
Project El Plomo Central
February 2021
Another pilot flotation run resulted in the gold (86 gr/t), copper (9.9%), silver (620 gr/t) concentrate, obtained from the mineral characterized by the dominance of gold-bearing finely crystallized pyrite with the traditional presence of copper (chalcocite) and silver (stromeyerite, acanthite, proustite) minerals.
Results of this test open up possibility of industrial processing and commercialization of the concentrates acquired from the currently developing underground zone of the project.

In-mine ventilation system upgrade
Project El Plomo Central
January 2021
Due to the development of underground tunnel's length to the total of 345 meters, the ventilation system was upgraded in order to maintain the required efficiency of fresh air supply to the working points and to reduce the ventilation time after drilling and blasting operations.
