1.0 INTRODUCTION

2.0 BACKGROUND

The Design Criteria forms the basis for the process design for the Process Plant at the Mt Todd Gold Project. This data forms the basis for the definition of the Metsim model and the subsequent generation of the mass and energy balances. This Process Design Criteria document, together with the Process Flow Diagrams and mass and energy balances provide the information required for the design and specification of all equipment. In addition they allow for the development of schedules for reagents and utilities such as water and power. Any recovery or similar data stated in the Design Criteria are used for design purposes and should not be construed as a statement of predicted plant performance.

The Mt Todd Gold Project is a predominantly sulphide ore gold deposit located in the Northern Territory near Katherine. Measured deposits have shown a gold presence as high as 1.5g/t and averaging 0.94 g/t. The process plant and infrastructure has been designed to have a service life of up to 20 years.






BASE CASE – 33,000tpd THROUGHPUT FOR LIFE OF MINE The design for this option will be based on a plant that is capable of processing 33,000 tpd of ore at a cut off of 0.45g Au/t for the life of the mine.

A block flow diagram of the expected process is included below.

Piping

10/05/2013

A.21 Piping costs are factored off a percentage of the mechanical equipment supply costs per area. There will be no material differences for piping due to the larger mills, therefore reduced piping factor for 33,000 tpd to reflect the same costs as the 30,000 tpd case for area 3300. No other factors changed. There will be minor increases in the leach area piping requirements due to the additional tank.

1.0 INTRODUCTION

2.0 BACKGROUND

The Design Criteria forms the basis for the process design for the Process Plant at the Mt Todd Gold Project. This data forms the basis for the definition of the Metsim model and the subsequent generation of the mass and energy balances. This Process Design Criteria document, together with the Process Flow Diagrams and mass and energy balances provide the information required for the design and specification of all equipment. In addition they allow for the development of schedules for reagents and utilities such as water and power. Any recovery or similar data stated in the Design Criteria are used for design purposes and should not be construed as a statement of predicted plant performance.

The Mt Todd Gold Project is a predominantly sulphide ore gold deposit located in the Northern Territory near Katherine. Measured deposits have shown a gold presence as high as 1.5g/t and averaging 0.85 g/t. The process plant and infrastructure has been designed to have a service life of up to 20 years.






50,000 TPD CASE The design for this option will be based on a plant that is capable of processing 50,000 tpd of ore at a minimum grade cut off of 0.4g Au/t for the life of the mine.

A block flow diagram of the expected process is included below.

Piping

8/05/2013

A.23 Piping costs are factored off a percentage of the mechanical equipment supply costs per area. There will be no material differences for piping due to the larger HPGR drives and mills, therefore reduced piping factor for 50,000 tpd to reflect the same costs as the 45,000 tpd case for areas 3200 and 3300. No other factors changed. There will be minor increases in the leach area piping requirements due to the additional tank.

Other

8/05/2013 A.26 Changed percentage of total cost for installation to reflect Thailand manufacture of steel. Does not affect total expected cost.


13/05/2013A.27 Revised contingency of 25% added to areas that have been further factored from the 45,000 tpd case to account for less design and accuracy. This applies to the following changes concrete (A.7 - A.10), structural steel (A.12-A.14), Tanks (A.20 and A.22), piping (A.23) and electrical (A.24).

Determined by structural engineers and drafters with reference to 3D models. Accounts for wider dump pocket.As above.

16. Factor applied to MTO's for additional tank ring beam for the additional Leach tank for the 50,000 tpd case

18. Factor applied to MTO's for larger detox tanks for the 50,000 tpd case (applied to slab and ring beam only)

19. Factor applied to MTO's for larger reagent tanks for the 33,000 tpd case (applied to all MTOs)


Estimated by structural and process engineers based on impact of bund volume by larger detox tank diameters. Assumed to be directly proportional to throughputEstimated by structural and process engineers based on impact of bund volume by larger reagent tanks. Calculated using the six tenths rule.

17. Factor applied to MTO's to increase bund wall height for larger tanks for the 50,000 tpd case for the additional leach tank

Estimated by structural and process engineers based on impact of bund volume by addition of another tank

Description1. Design factor applied to total costs to allow for bolts, brackets, pipe racks etc. plus an additional 5% to account for incomplete design/ engineering.

2. As above

5. As above

4.Scaling factor applied to MTO's to account for additional structural steel for the 30,000 tpd to the 45,000 tpd case

3. Design Factor applied to total costs to allow for bolts, brackets, pipe racks etc.

Estimated by structural and process engineers based on impact of larger mill dimensions. Takes into account extension of platform.


Estimated by structural and process engineers based on impact of larger reagent tanks sizes. Calculated using the six tenths rule.

16. Factor applied to MTO's to increase to account for the larger mills for the 33,000 tpd case (applied to all MTO's)
