  • Gold
  • Ethiopia
  • 1.5 Mtpa


  • Project Design & Economics Optimisation
  • Strategic Direction of Project Implementation
  • Major Contract Evaluation Process to Award
  • Feasibility Study Review


KEFI Minerals acquired 100% ownership of the Tulu Kapi Gold Project in Western Ethiopia in 2014 and are proceeding to progress the project to operation.

We were engaged to assist KEFI advance the project from definitive feasibility study (DFS) through an optimisation review and through to development. We investigated all aspects of the project including technical, commercial, mining, environmental and community sustainability components and evaluated construction and mining operation options. We optimised the plant layout based on the site topography, in relation to mining operations. This resulted in a significant reduction in earthworks and haulage distances and subsequent capital and operating expenditure.

In conjunction with KEFI, we reviewed potential contracting strategies with major EPC/EPCM companies, mining operators, service and infrastructure providers to obtain a viable project direction and workable financing arrangements. To do this we undertook financial modelling, risk mitigation analysis and presented a range of scenarios for financial and commercial implementation.

It is a highly successful ongoing collaboration between KEFI Minerals and Increva staff, resulting in the Executive Chairman Harry Anagnostaras-Adams saying that KEFI was very pleased with our professionalism, work ethic and specialist advice.


  • Graphite
  • Mozambique
  • 1.2Mtpa


  • Owners Representative for the PFS/DFS Phase
  • Identification & analysis of strategic project scoping options
  • Coordination of study consultants


The Montepuez & Balama Central Graphite Project is located in the Northern province of Gabo Delgado in Mozambique. Metals of Africa (MTA) announced its maiden mineral resource for the Montepuez Graphite project in November 2015 and its second maiden resource for the Balama Central project in March 2016.

Spherical graphite, which is derived from natural flake graphite, is an integral component of the growing market for Li-ion batteries (LiB). The growing markets for clean energy, for example, electric vehicles using LiB’s and energy storage system’s market are driving demand for reliable, low cost, high quality graphite concentrate. Spherical graphite derived from natural graphite, is produced at approximately 1/3 the cost of synthetically produced spherical graphite, which currently dominates the market. MTA is focused on developing flake graphite to anode ready spherical graphite for LiB production which is anticipated to increase by about 40% per annum.

The Montepuez & Balama Central Graphite Project boasts a large proportion of natural graphite classified as large-jumbo flakes which command premium prices and generally equates to lower impurities leading to higher recovery.

MTA engaged Increva to act as its representative for the project management of the PFS/DFS phases of development. The MTA/Increva team have worked to identify and analyse strategic options for the project scope and study development alternatives, to fast track the completion of the DFS by end of the 4th Qtr 2016.

Brownfields Constructability Review

Increva was engaged to assist Newcrest with brownfields constructability reviews for a variety of projects at its Telfer mine.  In particular, we provided experienced construction management advice during the planning stage of the T2 pebble screen  structural remediation project, which was to be carried out during a 40 hr shutdown.

Services included detailed review of the implementation schedule, manning and equipment levels to assist Newcrest’s objectives of a safe, efficient shutdown.



  • Brownfields Constructability Review


BHPBilliton Iron Ore conducted an upgrade of the drinking water supply, treatment and distribution system at Mining Area C, near Newman in WA, to improve compliance with BHPBIO WAIO Drinking Water Standards.

The project was a multi-discipline project requiring civil, structural, mechanical, piping, electrical and instrumentation and HV services as part of its scope of works.

The scope of the project included the provision of a new potable water distribution system at Area C. This included construction of a new water treatment plant and distribution system. The works also included the upgrade of the existing distribution system such that the future capacity requirements of Area C and the planned South Flank project could be met.

In conjunction with BHPBilliton, we participated in a constructability review to optimise the delivery of the project. The review was a collaboration between the Owner’s project team and the EPC engineer, with representation from operations and maintenance. Increva provided independent constructability and implementation advice, which influenced the design and construction methodology of the project.
