Key Risks

There are a number of factors, specific to Global Geoscience and of a general nature, which may affect the future operating and financial performance of Global Geoscience and the industry in which it operates. This section discusses some of the key risks associated with an investment in shares in Global Geoscience. These risks may affect the future operating and financial performance of Global Geoscience and the value of Global Geoscience shares. The risks set out below are not listed in order of importance and do not necessarily constitute an exhaustive list of all risks involved with an investment in Global Geoscience. Before investing in Global Geoscience, you should consider whether this investment is suitable for you. Potential investors should consider publicly available information on Global Geoscience (such as that available on the websites of Global Geoscience and ASX), carefully consider their personal circumstances and consult their professional advisers before making an investment decision. Additional risks and uncertainties that Global Geoscience is unaware of, or that it currently considers to be immaterial, may also become important factors that adversely affect Global Geoscience’s operating and financial performance. You should note that the occurrence or consequences of many of the risks described in this section are partially or completely outside the control of Global Geoscience, its directors and senior management. Further, you should also note that this section focuses on the potentially key risks and does not purport to list every risk that Global Geoscience may have now or in the

• future. It is also important to note that there can be no guarantee that Global Geoscience will achieve its stated objectives or that any forward looking statements or forecasts contained in

this Presentation will be realised or otherwise evaluated. All potential investors should satisfy themselves that they have a sufficient understanding of these matters, including the risks described in this section, and have regard to their own investment objectives, financial circumstances and taxation position. Cooling off rights do not apply to the acquisition of shares. Rhyolite Ridge Lithium-Boron Project new development Global Geoscience Limited intends to develop the Rhyolite Ridge Lithium-Boron Project. The development of the Project will require establishment of a minesite, construction of a processing plant, haulage road, ancillary infrastructure including an accommodation camp, securing and maintaining adequate water supply including bore field access and licensing, pump and pipeline infrastructure, as well as a number of operating contracts, among other things. Like typical greenfield mining project developments of this nature, there are risks and uncertainties that are associated with the development of Rhyolite Ridge, such as unexpected technical, geographical, metallurgical, meteorological, geological, third party access, community issues, or inclement weather. If they were to eventuate, these risks and uncertainties could result in Global Geoscience not achieving its development plans, or such plans generating less revenue than expected, costing more than expected or taking longer to realise than expected. Any of these outcomes could have an adverse effect on Global Geoscience’s expected financial and operating performance. Pre-feasibility study/future milestones As Global Geoscience progresses the development of its Rhyolite Ridge Project, there are risks and uncertainties involved which could result in Global Geoscience not delivering on its anticipated timing or costs for its pre-feasibility study or future milestones. Any of these outcomes could have an adverse effect on Global Geoscience’s expected financial and operating performance. Cost inflation Higher than expected inflation rates generally, or specific to the mining industry in particular, could be expected to increase development and operating costs and potentially reduce the value of future project developments. While, in some cases, such cost increases might be offset by increased selling prices, there is no assurance that this would be possible. To the extent that such offset is not possible, this could adversely impact Global Geoscience’s financial performance.

Key Risks (continued)

Production and cost estimates Global Geoscience has prepared a range of target cash costs for its operations. No assurance can be given by the Company that such targets will be achieved. Capital costs may be affected by unexpected modifications to plant design, changes to estimates of non-fixed components, delays in commissioning and sourcing financing. Failure to achieve cost targets or material increases in costs could have an adverse impact on Global Geoscience's future cash flows, profitability, results of operations and financial condition. Water sources Any restrictions on Global Geoscience’s ability to access water may adversely impact the costs, production levels and financial performance of its operations. There is no guarantee that the source of water Global Geoscience intends to utilise will support Global Geoscience’s water demands in relation to its sites and operations or that access to water will otherwise remain

• uninterrupted. Any interruption to water access could adversely affect production and Global Geoscience’s ability to develop or expand projects and operations in the future. In addition,

there can be no assurance that Global Geoscience will be able to obtain alternative water sources on commercially reasonable terms or at all in the event of prolonged drought conditions or

• ther interruptions to existing water access arrangements.

Reserves and Resources To date, Global Geoscience has only released a Resource Statement. Global Geoscience’s JORC Ore Reserves and Mineral Resources are expressions of judgement based on industry practice, experience and knowledge and are estimates only. Estimates of Ore Reserves and Mineral Resources are necessarily imprecise and depend to some extent on interpretations which may prove inaccurate or incorrect. No assurance can be given that the estimated Ore Reserves and Mineral Resources are accurate or that the indicated level of lithium carbonate, boric acid or any other mineral products will be achieved. Such estimates are, in large part, based on interpretations of geological data obtained from drill holes and other sampling

• techniques. Actual mineralisation or geological conditions may be different from those predicted. No assurance can be given that any or all of Global Geoscience’s Mineral Resources

constitute or will be converted into Ore Reserves. Actual Ore Reserves and Mineral Resources may differ from those estimated, which could have a positive or negative effect on Global Geoscience's financial performance. Commodity price fluctuations as well as increased production and capital costs may render Global Geoscience’s Ore Reserves unprofitable for periods of time or may render Ore Reserves containing relatively lower grade mineralisation uneconomic. Estimated Ore Reserves may have to be recalculated based on actual production experience. Any of these factors may require Global Geoscience to reduce its Ore Reserves and Mineral Resources, which could have a negative impact on Global Geoscience’s financial results and the expected operating life of the Project. Community relations Global Geoscience’s mining activities may cause issues or concerns with the local community in connection with, among other things, the potential effect on the environment as well as other social impacts relating to employment, use of infrastructure and community development. If such issues or concerns were to arise, this may have an adverse effect on Global Geoscience’s reputation and relationships with key stakeholders, which may in turn negatively impact its financial and operational performance.

Key Risks (continued)

Operational risks Mining operations generally involve a high degree of inherent risk and uncertainty. Such operations are subject to all the hazards and risks normally encountered in the exploration, development and production of lithium carbonate, boric acid and other mineral products, including unusual and unexpected geologic formations, metallurgical recovery and other processing problems, industrial accidents, wall failure, seismic activity, rock bursts, cave-ins, flooding, fire, access restrictions, interruptions, inclement or hazardous weather conditions and other conditions involved in the drilling, blasting and removal or processing of material, any of which could result in damage to, or destruction of, mines and other processing facilities, damage to life or property, environmental damage and possible legal liability. Global Geoscience is further subject to all of the risks associated with establishing new mining, processing and haulage and transport operations including the timing and cost of the construction of mining and processing facilities, the availability and costs of skilled labour and mining equipment, the need to

• btain additional environmental and other governmental approvals and permits and the availability of additional funds if required to further finance construction and development activities.

Funding risk Global Geoscience's continued ability to operate its business and effectively implement its business plan over time will depend in part on its ability to raise funds for operations and growth

• activities. Existing funds (including the funds raised under the Offer) may not be sufficient for expenditure that might be required for acquisitions and new or existing projects. There can be

no guarantee that Global Geoscience will be able to raise sufficient funding on acceptable terms or at all. An inability to obtain finance on acceptable terms or at all may cause, among other things, substantial delays in, or prevent, the development or operation of the Rhyolite Ridge Project. To the extent that Global Geoscience does require funding for its future capital needs, the availability and terms of such funding are uncertain and may be less favourable to Global Geoscience than anticipated, which may negatively impact Global Geoscience’s future profitability and financial flexibility. Funding terms may also place restrictions on the manner in which Global Geoscience conducts its business and impose limitations on Global Geoscience’s ability to execute on its business plan and growth strategies. Tax and customs risk Global Geoscience is subject to taxation and other imposts in Australia and the USA, as well as other jurisdictions in which Global Geoscience has activities and investments. Changes in taxation laws (including transfer pricing), or changes in the interpretation or application of existing laws by courts or applicable revenue authorities, may affect the taxation or customs treatment of Global Geoscience’s business activities and adversely affect Global Geoscience’s financial condition. Further, there may be delays in processing, tax or duty rebates or refunds for which Global Geoscience has applied. Should it become unlikely that Global Geoscience will recover such rebates or refunds, this could also adversely affect Global Geoscience’s financial condition and require a reclassification of assets or recognition of expenses in the Company’s accounts. Dependence on key management personnel Global Geoscience is dependent upon a number of key management personnel. The loss of the services of one or more of these personnel could have a material adverse effect on Global

• Geoscience. Global Geoscience’s ability to manage its operations, development and exploration activities, and hence its success, will depend in large part on the efforts of these individuals.

Offtake agreements To date, Global Geoscience has not entered into any offtake agreements with third parties. In the event it does, as with all contracts, there is a risk that the offtake parties may not perform their respective obligations or may breach the offtake agreements. In addition there is a risk that an offtake party may become insolvent or may not be able to meet its future buying or equity subscription obligations under the relevant offtake agreement.

ASX: GSC 35

Key Risks (continued)

Commodity prices and foreign exchange Global Geoscience’s revenues will in time be exposed to fluctuations in the prices for the minerals it produces including the price of lithium carbonate and boric acid. Volatility in these prices creates revenue uncertainty and requires careful management of business performance and cashflows. Lower prices can impact operations by requiring a reassessment of the feasibility of mine plans and certain projects and initiatives. Even if a project is ultimately determined to be economically viable, the need to conduct such a reassessment could potentially cause substantial delays and/or may interrupt operations, which may have a material adverse effect on Global Geoscience’s results of operations and financial condition. The factors which affect the price for lithium carbonate and boric acid (many of which are outside the control of Global Geoscience and its directors) include, among many other factors, manufacturing activities; the quantity of global supply in lithium carbonate and boric acid as a result of the commissioning of new mines and the decommissioning of others; political developments in countries which produce and consume material quantities of lithium carbonate and boric acid; the weather in these same countries; the price and availability of appropriate substitutes; advancements in technologies and the uses and potential uses of lithium carbonate and boric acid, and the demand for the applications for which lithium carbonate and boric acid may be used; the grade and quality of lithium carbonate and boric acid produced; and sentiment or conditions in the countries and sectors in which Global Geoscience and its business/commercial partners sell or intend to sell their products. Given the range of factors which contribute to the price of lithium carbonate and boric acid, and the fact that pricing is subject to negotiation, it is particularly difficult for Global Geoscience to predict with any certainty the prices at which Global Geoscience will sell its product and accordingly, investors are cautioned not to place undue reliance on any price or demand forecasts provided by Global Geoscience or by external analysts. Movements in currency exchange rates may affect cash flows, profitability, costs and revenue. It is not possible to accurately predict future movements in exchange rates. As Global Geoscience moves into production it will consider hedging strategies to mitigate this risk. Contract and counterparty risk The ability of Global Geoscience to achieve its stated objectives will depend on the performance of contractual counterparties. Global Geoscience may enter into various agreements for the construction, development and operation of the Rhyolite Ridge Project (including the supply of equipment, construction services, diesel fuel supply, contract mining and product handling and logistics). Should any of the risks associated with entering into these agreements materialise, this could have a material adverse impact on Global Geoscience’s profitability and financial performance. If Global Geoscience’s counterparties default on the performance of their respective obligations, for example if an offtake counterparty defaults on payment or a supplier defaults on delivery, it may be necessary to approach a United States or other international court to seek enforcement or some other legal remedy, if no alternative settlement can be reached. Such legal action can be uncertain, lengthy and costly. There is a risk that Global Geoscience may not be able to seek the legal redress that it could expect under Australian law against a defaulting counterparty, or that a legal remedy will not be granted on satisfactory terms. In addition, the sale of lithium carbonate and boric acid by Global Geoscience is subject to commercial verification and qualification processes to ensure any produced product meets the specifications for industrial supply required by customers under any offtake and supply agreements. The qualification process may require approval from multiple parties in the supply chain and not just those parties with whom Global Geoscience has contractual arrangements. Failure to have Global Geoscience’s product qualified, or any unanticipated delay in qualifying Global Geoscience’s product, may adversely impact Global Geoscience’s financial performance and position (including by resulting in Global Geoscience generating less revenue or profit than anticipated and/or incurring higher costs than anticipated). Competition Global Geoscience competes with other companies, including major mineral exploration and production companies. Some of these companies have greater financial and other resources than the Company and, as a result, may be in a better position to compete for future business opportunities. Many of the Company’s competitors not only explore for and produce minerals, but also carry out refining operations and other products on a worldwide basis. There can be no assurance that Global Geoscience can compete effectively with these companies.

ASX: GSC 36

Key Risks (continued)

Environmental risk Global Geoscience’s operations and activities are subject to environmental laws and regulations. As with all mining operations and exploration and development projects, Global Geoscience’s operations may substantially impact the environment or cause exposure to or omission of hazardous materials, which could result in substantial costs being incurred for environmental risk management, rehabilitation and damage control. Further, environmental conditions may be attached to mining tenements and other permits and approvals, and a failure to comply with these conditions may lead to their forfeiture. Global Geoscience is also unable to predict the effect of additional environmental laws and regulations which may be adopted in the future, including whether any such laws or regulations would materially increase Global Geoscience’s cost of doing business or affect its operations in any manner. Regulatory Global Geoscience’s operations are dependent upon the grant, maintenance or renewal of appropriate licences, concessions, leases, permits and regulatory consents which may be withdrawn or made subject to limitations. Approvals, licences and permits required to comply with such rules may, in some instances, be subject to the discretion of the applicable government or government officials. No assurance can be given that Global Geoscience will be successful in obtaining any or all of the various approvals, licences and permits or maintaining such authorisations in full force and effect without modification or revocation. To the extent such approvals are required and not retained or obtained in a timely manner or at all, Global Geoscience may be curtailed or prohibited from continuing or proceeding with production, development and exploration. The operations of Global Geoscience are subject to various laws and plans including those relating to mining, prospecting, development, permit and licence requirements, industrial relations, environment, land use, royalties, water, native title and cultural heritage, land access, mine safety and occupational health. Amendments to current laws, regulations and permits,

• r a more stringent implementation thereof, could have a material adverse impact on Global Geoscience and cause increases in exploration expenses, capital expenditures or production

costs, reduction in levels of production at producing properties, or abandonment or delays in development of new mining properties. Government actions Global Geoscience’s operations could be adversely affected by government actions in the United States or other countries or jurisdictions in which it has operational exposures or investment or exploration interests. These actions include, but are not limited to, the introduction of or amendment to or changes in the interpretation of legislation, guidelines and regulations in relation to mining and resources exploration and production, taxation, the environment, carbon emissions, competition policy and so on. Such actions could impact upon land access, the granting of licences and permits, the approval of project developments and ancillary infrastructure requirements and the cost of compliance. The possible extent of the introduction of additional legislation, regulations, guidelines or amendments to existing legislation that might affect Global Geoscience is difficult to predict. Any such government action may require increased capital commitments in order to ensure compliance or could delay or even prevent certain operation/activities of Global Geoscience. Such actions could therefore have a material adverse effect on Global Geoscience’s financial condition. Global Geoscience’s business could be affected by new or evolving trade regulations and international standards, such as controls on exports, prices and sanctions restricting or regulating trading with, or the sale or purchase of goods or products to or from, entities in the United States or other jurisdictions relevant to Global Geoscience’s business, any of which could adversely impact Global Geoscience’s sales and profitability. Labour risks Global Geoscience believes that all of its operations have, in general, good relations with their employees. However, there can be no assurance that the Company’s operations will not be affected by labour related problems in the future, such as disputes for pay raises or increased benefits etc. There are risks associated with staff, no matter where located, acting out of their permitted authority and with contractors not acting in accordance with the Company’s policies.

ASX: GSC 37

Key Risks (continued)

Insurance and uninsured risks Although Global Geoscience maintains insurance to protect against certain risks in such amounts as it considers to be reasonable, its insurance is unlikely to cover all the potential risks associated with its operations and insurance coverage may not continue to be available or may not be adequate to cover any resulting liability. It is not always possible to obtain insurance against all such risks and the Company may decide not to insure against certain risks because of high premiums or other reasons. Moreover, insurance against risks such as environmental pollution or other hazards as a result of exploration and production is not generally available to the Company or to other companies in the mining industry on acceptable terms. Access to infrastructure Development and mining activities depend on adequate and reliable access to land and infrastructure, including roads, rail crossings, pipeline and services corridors, power sources and water supplies. Security of tenure The maintaining of tenements, obtaining renewals, and grant of tenements or permits (including for both construction and mining operations) depends on Global Geoscience being successful in obtaining statutory approvals for its proposed activities. There can be no assurance that such approvals will be obtained and there is no assurance that new conditions or unexpected conditions will not be imposed. If such approval or not obtained or new or unexpected conditions are imposed, this could have a material adverse impact on Global Geoscience’s operational and financial performance. Litigation Global Geoscience may be involved in litigation and disputes from time to time with its contractors, sub-contractors and other parties. Litigation and disputes can be costly, including amounts payable in respect of judgments and settlements made against, or agreed to by, Global Geoscience. They can also take up significant time and attention from management and the

• Board. Accordingly, Global Geoscience’s involvement in litigation and disputes could have an adverse impact on its financial position and performance.

Global economic conditions Economic conditions, both domestic and global, may affect the performance of Global Geoscience. Adverse changes in macroeconomic conditions, including global and country‐specific growth rates, the cost and availability of credit, the rate of inflation, interest rates, exchange rates, government policy and regulations, general consumption and consumer spending, input costs, employment rates and industrial disruptions, among others, are variables which while generally outside the control of Global Geoscience and its Directors, may result in material adverse impacts on Global Geoscience’s businesses and its operational and financial performance. Safety management Global Geoscience’s ability to attract new business in the future is dependent on many factors, including Global Geoscience’s ability to demonstrate that it can reliably and safely deliver the

• services. Potential clients consider the safety record of their service providers to be of high importance in their decision to award service contracts. Some of Global Geoscience’s activities

are by their nature among the higher risk activities undertaken. If one or more accidents were to occur at one of its sites, potential clients may be less likely to deal with Global Geoscience. A general deterioration in Global Geoscience’s safety record could have a material adverse impact on Global Geoscience’s business, including its ability to attract and retain qualified employees or to win future supply contracts. Global Geoscience could also be subject to liability for damages as a result of any such accidents and could incur penalties or fines for violations of applicable safety laws and regulations.

Key Risks (continued)

Underwriting risk Global Geoscience expects to enter into an underwriting agreement with the underwriter, who expects to manage and fully underwrite the Placement, subject to certain terms and

• conditions. If certain conditions are not satisfied or certain events occur, the underwriter may terminate the underwriting agreement.

Termination of the underwriting agreement could result in the Offer not proceeding or not raising the anticipated amount of proceeds, and accordingly materially adversely affect Global Geoscience's business, cash flow, financial condition and results of operations. In this event, Global Geoscience may be required to source funding by alternative means, which may result in additional costs (for example, by way of interest payments on debt) and/or restrictions being imposed on the manner in which Global Geoscience may conduct its business and deal with its assets (for example, by way of restrictive covenants binding upon Global Geoscience). Share price fluctuations The market price of the Company’s shares will fluctuate due to various factors, many of which are non‐specific to Global Geoscience, including recommendations by brokers and analysts, Australian and international general economic conditions, inflation rates, interest rates, changes in government, fiscal, monetary and regulatory policies, global geo‐political events and hostilities and acts of terrorism, and investor perceptions. Fluctuations such as these may adversely affect the market price of the Company’s shares. Neither Global Geoscience nor the Directors warrant the future performance of Global Geoscience or any return on an investment in Global Geoscience. Liquidity risk There can be no guarantee of an active market in the shares in Global Geoscience or that the price of the shares in Global Geoscience will increase. There may be relatively few potential buyers or sellers of Global Geoscience's shares on the ASX at any time. This may increase the volatility of the market price of Global Geoscience's shares. It may also affect the prevailing market price at which shareholders are able to sell their shares in Global Geoscience. Dilution The Offer is being conducted by way of an Institutional Placement under Part 6D of the Corporations Act to “sophisticated investors” and “professional investors” (within the meaning of sub- sections 708(8) and 708(11) of the Act respectively). As such, not all existing Global Geoscience shareholders will be provided the opportunity to participate in the Offer either to the full extent of the pro rata shareholding or at all. The percentage holdings in Global Geoscience of these affected shareholders will be diluted by the Placement from both an ownership and value perspective. Political risk, war and terrorism, force majeure and sovereign risk Global Geoscience’s operations could be affected by political instability in Australia, the United States or other countries or jurisdictions in which it has operations, investment interests, or conducts exploration activities. Global Geoscience is therefore subject to the risk that it may not be able to carry out its operations as it intends or to ensure the security of its assets and its people (particularly those located outside of Australia). Given its geographic footprint, Global Geoscience is subject to the risk of, among other things, loss of revenue, property and equipment as a result of expropriation, war, insurrection, civil disturbance, acts of terrorism and geopolitical uncertainty. The effect of these risks is difficult to predict and any combination of

• ne or other of the above may have a material adverse effect on Global Geoscience. Global Geoscience has a limited ability to insure against some of these risks and other 'force majeure‘

risks (such as natural disasters). Accounting standards Australian accounting standards are set by the Australian Accounting Standards Board (AASB) and are outside Global Geoscience’s control. Changes to accounting standards issued by AASB could materially adversely affect the financial performance and position reported in Global Geoscience’s financial statements.
