Mining district

District name Essequibo, Mackenzie, Kwakwni, Ituni Districts

Comments on the production information

  • HISTORICALLY, THIS DISTRICT IS THE MOST IMPORTANT DIAMOND PRODUCER IN BRAZIL. MINERACAO TEJUCANA CAN MINE GRAVELS WITH AS LITTLE AS 0.008 CARATS PER CUBIC METER ECONOMICALLY, AVERAGE GRADE OF GRAVEL RUNS 0.05-1.5 CARATS PER CUBIC METER.

Comments on the reserve resource information

  • 1) THE AVERAGE COMPOSITION OF ALUMINOUS LATERITES: 36% AL2O3, 14.3% SIO2, 24.4% FE2O3, 2% TIO2 2) THIS GRADE REFERS TO AVERAGE COMPOSITION OF BAUXITE.

Comments on the workings information

  • DREDGING.

Comments on development

  • MINERACAO TEJUCANA IS THE LARGEST PRODUCER IN THE DISTRICT.
  • THE BAUXITE DEPOSIT ZONE EXTENDS FROM POMEROON RIVER (NW) TO CORENTYNE RIVER (SE). MAIN DEPOSITS INCLUDE ESSEQUIBO DISTRICT NEAR BARTICA (NW) AND MACKENZIE DISTRICT NEAR DEMERARA RIVER (SE).
