Current Operations


The Çaldag mine in western Turkey is located near the deep port of Izmir.

The Project

The project has been designed to be a low cost, open pit operation, which will produce 20,000tpa of nickel and 1,000tpa of cobalt in a mixed hydroxide product (MHP) over a 14 year life of mine. This will be sold for processing into nickel and cobalt metal.  The deposit’s JORC proven reserves are 33.2Mt at 1.13%Ni (375,160t contained Ni).

The Çaldag project has been progressed to the point whereby the only outstanding item to successfully concluding the Western Bank project financing and commencing development of the project is the re-issuance of the forestry permit. Despite repeated assurances that the forestry permit will be re-issued, the Board has decided to put Çaldağ on care and maintenance and suspend project financing until such time that it receives the outstanding forestry permit. Upon receipt of the permit, the Board will re-assess the situation in light of the progress and development of the Acoje project.

Acoje & Zambales

The Acoje and Zambales deposits are based on Luzon Island in the Philippines.  The deposits have a combined JORC resource of 840,000 contained tonnes of nickel. The Company is fast tracking a Definitive Feasibility Study (DFS).

The proposed mining operation at Acoje will have a significant positive economic impact on the local and regional community.

Pre-Feasibility Study

A positive PFS demonstrated an economically viable, heap leach nickel laterite project, producing 24,500tpa nickel and 930tpa cobalt in mixed hydroxide product (MHP) over an initial 10 year life of mine. There is significant potential to extend the mine life by converting the JORC Inferred Acoje and Zambales Chromite deposits to JORC Indicated status.

The total development cost is estimated at US$498 million including infrastructure and working capital.

Definitive Feasibility Study

A DFS is underway at Acoje, which includes large scale batch testwork at the Acoje Test Centre (ATC). The test work programme for the 4m full column tests has passed its 100 day mark and is progressing in line with expectation. The ATC will provide all the metallurgical data required for the DFS.

In addition to the DFS, ENK will run a full scale heap leach trial to demonstrate the operability of the heap leach process under Philippines equatorial conditions, such as the use of raincoats. The DFS timeline is not dependent on the commencement of the heap leach trial.

The Zambales Deposit

At the Zambales deposit, an exploration programme focusing on the nickel saprolite ore is underway to increase the resource further.


The Berong mine is located on Palawan Island in the Philippines and majority owned by Toledo Mining (AIM: TMC).  ENK has a 23.7% beneficial interest in Berong Nickel Corporation (BNC) and a 7.7% interest in Toledo Mining.

Berong’s current JORC resource (compiled June 2007) is 9.92Mt at 1.55% nickel and represents only a small percentage of the tenement area.  There is strong potential to significantly increase this and a drilling programme is underway to prove up a JORC resource of around 30Mt. A total JORC resource of 40Mt is considered sufficient to support a 20,000tpa nickel processing operation.

Devolli/Koko JV

ENK is in a joint venture with the privately owned Balkan Resources to jointly develop Balkan’s Kokogllave (“Koko”) and ENK’s contiguous Devolli nickel laterite deposits in Albania.

The deposits are located in south-eastern Albania, close to the Greek border.  The Devolli nickel laterite deposit has a JORC resource of 427,000 tonnes of contained nickel (35.6 million tonnes at 1.20% nickel).  Balkan has completed a NI 43-101 technical report on its Koko nickel laterite deposit and it is intended to develop both deposits as one single mining operation. The Koko tenement has a historic resource estimate, which is neither JORC nor 43-101 compliant, of approximately 30 million tons at a grade of approximately 1.2% nickel.

Under the terms of the agreement, Balkan will earn its 50% interest in the joint venture by contributing the Koko deposit and funding, through to completion, a Pre-Feasibility Study (“PFS”) on the combined Koko/Devolli deposits to Canadian NI 43-101 standards. ENK will earn its 50% interest by contributing the Devolli deposit and granting access, via a licence agreement, to its heap leach technology, knowledge and experience.

If Balkan fails to complete the PFS by 31 December 2010, it shall transfer its interest in the Koko deposit plus all engineering, exploration and other data and studies conducted as part of the PFS to ENK for nil consideration.

The PFS, expected to cost some US$5-7 million, will require extensive drilling to bring sufficient tonnes into the indicated category to support a proposed production of 15,000-20,000 tonnes a year of contained nickel over a mine life of 15 to 20 years.  It will also be necessary to compile the engineering, mine development planning, environmental, infrastructure and other reports to substantiate the viability of this operation.
