Concurrently 34 geotechnical gaps, totaling 2 896 meters was basically accomplished for exploit engineering structure aim. After the achievement of your own drilling program the company embarked to your detailed metallurgical assessment of numerous you can easily procedure choices for the latest mineral areas. At the conclusion of 1994, the business began pre-feasibility degree.
