While doing so 34 geotechnical openings, totaling 2 896 meters had been accomplished for mine technologies build motives. Following the achievement of the drilling system the company embarked to your comprehensive metallurgical evaluation of a lot you’ll be able to processes alternatives for the fresh new mineral zones. At the end of 1994, the business began pre-feasibility training.
