Geodynamics Limited : Savo Island Inferred Geothermal Resource Assessment

? Median Initial Inferred Geothermal Resource of 269 PJth estimated to be capable of supporting in excess of 30 MWe of generation capacity on Savo island

? Potential generation capacity to supply 100% of the power requirement of city of

Honiara and nearby Gold Ridge Mine

? Finalisation of Initial Resource Assessment and Scoping Study complete Stage One of the Earn- In Joint Venture Agreement

Geodynamics Limited (ASX:GDY) and its joint venture partner Kentor Energy Pty Ltd, a subsidiary of Kentor Gold Ltd (ASX:KGL) ("Kentor"), are pleased to announce that initial exploration studies have confirmed the presence of a high quality geothermal exploration prospect at their Savo Island Project in the Solomon Islands.

In November 2012, Geodynamics entered into an agreement with Kentor for Geodynamics to acquire up to a 70% interest in the Savo Island Geothermal Project through a two stage earn-in agreement under which Geodynamics would earn an initial 25% through funding initial exploration activities, and could earn a further 45% through funding exploration drilling and completion of a feasibility study. Since the completion of this agreement a magneto telluric geophysical survey (MT survey) covering 77 sites on the island has been completed and the results analysed to produce a
3D conceptual model and Initial Inferred Geothermal Resource Assessment of Savo Island.
The independent resource assessment, a summary of which is attached to this announcement,
was prepared in accordance with The Geothermal Reporting Code, Second Edition (2010). The full report was prepared by Volcanex International, and estimates a total median Inferred Geothermal Resource of 269 PJth within the prospecting license boundary. Using the P50 estimate the report concludes that Savo Island has a sufficient Recoverable Thermal Energy that if recovered and
converted would be adequate to generate 37 MWe for 30 years.

This generation capacity would be sufficient to supply more than the total current requirement of the city of Honiara and the Gold Ridge Mine, situated 25 km from Honiara.
The resource assessment provides sufficient information and confidence to justify the progression of further exploration activities, including exploration drilling, to prove the reservoir conditions and the prospectivity of the project for commercial electricity generation.
An independent peer review of the data by Sinclair Knight Merz Limited, a leading geothermal consulting company, states that "there is sufficient confidence in the resource assessment to encourage an exploration/production drilling programme in the most prospective area to the southeast of the crater."
In parallel to the completion of the initial resource assessment, a scoping study has been completed to assess the viability of potential development schemes to extract and deliver the
power from Savo Island. The scoping study assessed the potential for the development of a power
plant of up to 20 MWe and identified a viable potential project scheme that would bring significant benefits to all stakeholders.

Through the expenditure on preliminary exploration and the completion of the Resource Assessment and Scoping Study, Geodynamics has fulfilled its commitments under Stage One of the Earn -In Joint Venture with Kentor Energy. Completion of Stage One will see Geodynamics take a 25% interest in the Joint Venture along with operatorship of the Project.
With the completion of the initial technical studies, Geodynamics will now focus on progressing discussions with the relevant ministries within the government of Solomon Islands on planning and approvals for further exploration activities, and discussions with the Solomon Islands Electricity Authority in relation to electricity supply and power purchase agreements. Geodynamics is actively engaging with customary landowners through community consultations and workshops as we proceed with our next steps in advancing the project and would target initial exploration drilling to be undertaken during the 2014 dry season.
Geodynamics Managing Director and CEO Geoff Ward said "The completion of the initial resource estimate and scoping study is a key step in progressing the Savo Island Geothermal Power Project, which is aiming to replace high cost diesel generated power in Honiara and the nearby Gold Ridge Mine with cheaper and cleaner geothermal power. The positive outcome from the

initial resource assessment and scoping study confirms our initial assessment that Savo Island is a high quality geothermal project with significant potential to provide a cheaper, cleaner, more

reliable power to customers in the Honiara area than the current diesel power generation system. We look forward to working with the government of the Solomon Islands, the local community and customers to take this project forward.

With continued success in the exploration program and the positive engagement we have received from the Solomon Islands Government, the Savo Island Project could be supplying power to Honiara within 4 - 5 years."

About Savo Island Geothermal Power Project

The projects is a joint venture between Geodynamics Limited and Kentor Energy Pty Ltd a subsidiary of Kentor Gold Ltd.

The Project is located on the island of Savo, 14 km off the north coast of Guadalcanal where a volcanic based geothermal resource has been identified. Preliminary exploration studies indicate the island has sufficient Recoverable Thermal Energy that if recovered and converted would be adequate to generate 37 MWe for at least 30 years. A market of 20-30 MW is within ~60 km of the island, both Honiara and the Gold Ridge Mine are currently supplied by diesel generation.

Summary

Savo Island is the top 490 m of a 1,400 m high stratovolcano which displays numerous geothermal features including boiling jets and springs, sulphurous steaming fumaroles and areas of warm ground. Located 35 km from Honiara in the Solomon Islands, Savo is being explored to determine its potential for producing electricity that may be sold to the Honiara grid via a submarine cable.
A probabilistic stored heat Inferred Geothermal Resource estimate for Savo has been determined under the Australian Code for Reporting of Exploration Results, Geothermal Resources and Geothermal Reserves. It is based on a comprehensive geothermal conceptual model for the island which incorporates the nature and locations of the main surface thermal features, the geochemical and isotopic compositions of the thermal fluids, and a 3D model of the sub-surface resistivity structure derived from a 77-site magnetotelluric survey of the island.
In the conceptual model all of the known surface thermal fluids are considered to be of secondary origin, having formed as a result of having absorbed H2S, CO2 and steam evolved from the boiling tops of two hydrothermal convection cells about 350-500 m below the surface. The larger of about 6.5 km2 occurs in the southern part of the island and the smaller of about 2.6 km2 in the north.
The surface thermal fluids contain very little chloride but substantial and variable amounts of sulphate, silica and bicarbonate. Contrasting low-volume acid and high-volume alkaline sulphate fluids are thought to have been derived from small, near-surface ephemeral pools and a shallow flowing aquifer lying below the summit crater floor respectively. Silica contents suggest the formation temperatures of the latter are probably in excess of 200 °C.
Discharges of primary hydrothermal fluids from the deep convection cells are not known on Savo but probably occur offshore on the lower flanks of the volcano. Their temperature is estimated from the minimum temperatures at which they would boil directly below the surface sulphate fluids which, in view of the thickness of underlying conductive clay caps suggested by the 3D resistivity model, is about 210
°C to 250 °C. The absence of strong surface discharges of magmatic gases suggests the primary fluids are unlikely to be excessively acidic and therefore may be suitable for electricity generation.
The amount of thermal energy stored in the two resource areas can be inferred from the range of possible values for reservoir area, thickness and temperature. In conjunction with various other estimates and assumptions, particularly regarding the amount of heat that can be recovered from
depth, the probabilistic stored-heat Inferred Geothermal Resource estimate for Savo is as follows:

Savo Inferred Geothermal Resource Assessment 1

As there is a reasonable prospect for eventual economic extraction of the Inferred Geothermal
Resource its assumed electricity generation potential is as follows:

In terms of the Geothermal Reporting Code the Inferred Geothermal Resource estimate for Savo is associated with a relatively low level of confidence but it provides sufficient information and confidence to justify drilling to better determine the actual reservoir conditions and its suitability for commercial electricity generation.
The assumed electrical power potential estimate also has a relatively low level of confidence but it provides an indication that the Inferred Geothermal Resource on Savo is at least comparable in
magnitude to the Honiara electricity market.
