Project Brief

Karouni Gold Project: Detailed Design


CDMS successfully completed the detail design of the Karouni plant. The project has been both profitable and successful for Troy Resources in a new operating location.


The Karouni Gold Project lies approximately 180km south-southwest of Georgetown. The project covers an aggregate area of 113,581 hectares; comprising of small, medium and large scale tenements west of the Essequibo River.

Project Objectives

  • Deliver construction drawings for tender
  • Minimise CAPEX
  • Provide operational flexibility


  • Very high rainfall
  • Initial wet sticky ore changing to hard fresh ore
  • Cyanide free tailings dam using DETOX

Our Approach

CDMS relied heavily on its core technical knowledge base and previous industry experience during the design of the plant infrastructure; which included the complete process, chemical, metallurgical, mechanical, structural, and civil design components. The design covered the all the crucial facilities in the plant, including ore handling, conveyors, crushing and grinding, milling and classification, gravity concentration, pre-leach thickening, leaching and adsorption, cyanide destruction (detox), tailings Finite Element Analysis (FEA) stress analysis software was used to check the design of bins, chutes and storage hoppers, and Helix DeltaT6 was used to design the long run conveyors. Regular design development meetings were held between the client (Troy Resources), METS Engineering and CDMS personnel to facilitate a workable and improved plant design.
