GSL are undertaking pre-feasibility resource assessment, and metallurgical testing on samples from an African molybdenite deposit. Results of initial assays were positive showing head grades of between 0.22 and 0.5% molybdenum, but also showing good tin and zinc grades of 0.3-0.8%, and 0.4-1.9% respectively.
Metallurgical testing is planned for the gravity concentration of zinc and tin, and flotation testing for the recovery of molybdenum.
Some of the molybdenite in this deposit exhibits coarse mineralisation, as shown below.
