OCEAN BASED PROTEAN™ TEST SUCCESSFULLY COMPLETED OPTION TO ACQUIRE PROTEAN™ EXERCISED CAPITAL RAISING COMPLETED

Protean™ WEC ocean based test program successfully completed

Option to acquire 100% of Protean™ intellectual property exercised

$800,000 raised via convertible loan facility and oversubscribed placement

Executive team secured

Protean™ accelerated commercialisation program on track


Stonehenge Metals Limited (Stonehenge, or the Company) is pleased to advise that the functional ocean based testing of the fully assembled proof of commercial applicability ProteanTM Wave Energy Converter (WEC) device has been successfully completed. The testing showed that the ProteanTM WEC functioned as anticipated and that it was responsive to wave motion even in very low wave height conditions. Preparations for fabrication of the 30 ProteanTM WEC buoys which make up the planned pre-commercial demonstration wave farm have now commenced.
Building on the success of the testing program, the Company has now formalised its intention to complete the acquisition of 100% of the Protean™ intellectual property by exercising its rights under the option agreement (Option) between the Company and Protean Energy Ltd (PEL). Furthermore, the Company is pleased to announce that it has successfully completed a capital raising with sophisticated investors for $800,000 by way of a convertible loan facility and a heavily oversubscribed placement.
The Company remains focused on proving the commercial applicability of the technology through local, national and international collaborations with both existing and new supporters of the Protean™ WEC system.
Stonehenge MD, Bruce Lane said "The successful completion of ocean testing of the single proof of commercial applicability device was the next major milestone in our program to accelerate commercialisation of the Protean™ WEC technology. This is a pivotal moment for the Company and we are excited to have now exercised our option to acquire the Protean IP and to secure the ongoing commitment and services of both Sean Moore and Scott Davis. It is very pleasing to be in a position to commence building the 30 buoy demonstration wave farm so quickly."

More on: Ocean Testing

The functional ocean based testing program was successfully conducted at Coogee Beach, Western Australia, in approximately 2.5m of water, utilising only readily available equipment and personnel. The full assembly of the single proof of commercial applicability device was successfully tested including: beach launching equipment, Protean™ mooring, counterweights, buoy and energy conversion mechanism. Also tested was an extension to the development project; a prototype of an energy transmission and storage system with associated electrical generator used to power an array of nine (9) independent loads set up to demonstrate the modular scalability of the Protean Power™. The testing showed that the ProteanTM WEC was responsive to wave motion even in very low wave height conditions.
The next phase in the project execution is the fabrication of the 30 commercial applicability buoy demonstration array. Preparation for the build has commenced and is expected to be completed towards the end of 2015.

More on: Capital Raising

The Company has completed a placement to raise $500,000 to sophisticated investors via the issue of 12,500,000 new shares at 4 cents per share (Placement). The Placement was made pursuant to the Company's existing placement capacity under ASX Listing Rule 7.1. ASX will not quote the Placement securities until following recompliance and ASX escrow provisions will apply. Funds raised under the Placement will be used to fund continuing operations, completion of the acquisition and re-compliance with ASX Listing Rules.
The Company has also entered into an additional loan facility for up to $300,000 (Loan) with a small number of sophisticated investors (Lenders) including one of the Company's directors, Mr Bevan Tarratt. The Loan is convertible subject to shareholder approval and has material terms and conditions that are the same as the existing loan facility previously advised on 1 July 2015 as summarised in Schedule 1.

More on: Option Exercise, Name Change and Re-compliance with ASX Listing Rules

Pursuant to the Option the Company has entered into a Share Sale and Purchase Agreement with PEL, which specifies the terms on which the Company agrees to acquire 100% of the issued capital of Protean Energy Australia Pty Ltd (PEA) from PEL (Acquisition). The key terms of the agreement were previously announced to ASX on 14 August 2014 and are summarised in Schedule 2.
As part of the Acquisition, the Company will seek the approval of shareholders to change its name to Protean Wave Energy Limited. The Acquisition will result in a change in the Company's nature and scale of activities, requiring shareholder approval under Chapter 11 of the ASX Listing Rules and the Company will need to re-comply with Chapters 1 and 2 of the ASX Listing Rules. In order to re-comply with the ASX Listing Rules the Company expects to seek shareholder approval to, amongst other things, issue a re-compliance prospectus to raise sufficient funds to accelerate commercialisation of the Protean WEC technology. A notice of meeting to seek approval for the above matters, including the quantum of the capital raising, is expected to be dispatched in due course. The process of re-complying with ASX listing rules is not expected to require a consolidation of the Company's share capital.

ABOUT THE PROTEAN WAVE ENERGY CONVERTER (WEC) TECHNOLOGY

Stonehenge has exercised its option to acquire the Protean WEC technology. The Protean WEC system is based upon a point-absorber wave energy converter buoy device, which floats at the water surface and extracts energy from the waves by the extension and retraction of a tether to its anchoring weight on the seabed. The device is uniqu e in that it optimises the conversion of energy from waves at the surface through all six degrees of wave movement.

Figure 2: Protean WEC technology

The Protean WEC has been developed to use compact architecture to produce power from a small, low cost, scalable design targeted at keeping the projected levelised cost of energy (LCOE)1 down. The Protean WEC has been designed to be cost competitive to manufacture, deploy, maintain and retrieve. The future plans for the Protean WEC include the deployment of a pre-commercial demonstration of a dynamic, configurable and scalable power array prior to moving the technology into early commercialisation. During the Option period the Stonehenge assessment program aims to:

1. Refine the tried and proven scale device to produce a suitable pre-commercial model;

2. Create a scalable power array so as to provide the power requirements of a prospective customer;

3. Test the scalable power array for its potential to deliver cost effective power;

4. Verify the results, including commissioning of an independent expert to qualify the testing results; and

5. Commence commercialisation of the scalable array for small to medium customers.

1 Levelised cost of energy is one of the industry's main metrics for the cost of electricity produced. It accounts for all of a system's expected lifetime costs (incl. construction, finance, fuel, maintenance, tax, insurance & incentives), which are then divided by the system's lifetime expected power output (kWh) & discounted for inflation & time cost of money.
