A recent mine planning study based on the original drill data has indicated that at 1.0% nickel cut-off the combined resource for the project will be 357,000 tonnes at 1.30% nickel and 0.09% cobalt. The following table provides a summary of the results of the recent study on the higher grade material.

The modelled project results in the production of approximately 3,850 tonnes of nickel during the 5-6 year life of the operation, at an average operating cost equivalent to US$5.07/lb nickel ($A5.58/lb at the exchange rate provided above). It is noted that, as at the date of this release, the Australian dollar value of nickel was $11.56/lb (US$9.86/lb at an exchange rate of 0.85).
As outlined above, under the joint venture agreement with Metallica Minerals Limited, the Company will receive all project surplus until capital plus interest is fully repaid, with ongoing surplus after that time being shared equally between the parties.
On the basis of the analysis carried out the project remains financially positive under more adverse conditions, including:
An increase in capital costs of approximately $2M.
Revenue reduced due to a fall in nickel price by up to 10%.
An increase in operating costs by 10%
The directors note that the indicated result provided above is subject to firm pricing of equipment and consumables through establishment of formal contracts, in particular relating to acid supply for the ongoing operation. It will also be subject to potential variations in market and operating conditions through the potential life of the operation, including periodic and potentially adverse movements in the ruling value of nickel, exchange rates and possible newly imposed government taxes.
The feasibility study provides for a 12 month implementation schedule, including time required for establishment of supply contracts and arrangement of an appropriate funding structure.
The next stage of the Company's programme on Lucky Break will focus on the following key areas:
Analysis of the potential impact of a new resources tax regime in Australia
Procurement of the long term contract for acid supply
Negotiation of product sales arrangements
Confirmation and amendment if necessary of existing permits
Establishment of an appropriate funding mechanism for the project
Detailed engineering of the site and flow sheet
Establishment of fixed quotes for plant and machinery
The completed agreement with Metallica and the Definitive Feasibility Study place Metals Finance in a strong position to progress the development of the Lucky Break nickel project. |
