The presentation (in this projected form and as verbally presented) (“Presentation”) has been prepared by White Rock Minerals Limited and is provided on the basis that none of the Company nor its respective officers, shareholders, related bodies corporate, partners, affiliates, employees, representatives and advisers make any representation or warranty (express or implied) as to the accuracy, reliability, relevance or completeness of the material contained in the Presentation and nothing contained in the Presentation is, or may be relied upon as a promise, representation or warranty, whether as to the past or the future. The Company hereby excludes all warranties that can be excluded by law. The Presentation contains prospective financial material which is predictive in nature and may be affected by inaccurate assumptions or by known or unknown risks and uncertainties and may differ materially from results ultimately achieved. The Presentation contains “forward-looking statements”. All statements other than those of historical facts included in the Presentation are forward-looking statements. Where the Company expresses or implies an expectation or belief as to future events or results, such expectation or belief is expressed in good faith and believed to have a reasonable basis. However, forward-looking statements are subject to risks, uncertainties and other factors, which could cause actual results to differ materially from future results expressed, projected or implied by such forward-looking statements. Such risks include, but are not limited to, gold and other metals price volatility, currency fluctuations, increased production costs and variances in ore grade or recovery rates from those assumed in mining plans, as well as political and
The Presentation contains general background information about the Company and its activities current as at the date of this presentation. The information in this Presentation is in summary form only and does not contain all the information necessary to fully evaluate any transaction or investment. It should be read in conjunction with the Company’s other periodic and continuous disclosure announcements lodged with the ASX, which are available at www.asx.com.au and other publicly available information on the Company’s website at www.whiterockminerals.com.au. The information in this presentation that relates to Exploration Results is based on information compiled by Mr Rohan Worland who is a Member of the Australian Institute of Geoscientists. Mr Worland is engaged by White Rock Minerals Ltd as a technical consultant. Mr Worland has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’. The Exploration Potential described in this Presentation is conceptual in nature, and there is insufficient information to establish whether further exploration will result in the determination of a Mineral Resource. Mr Worland consents to the inclusion in this Presentation of the matters based on his information in the form and context in which it appears. The gold and silver Resource figures for Strauss, Kylo, Lady Hampden, Silver King, White Rock, White Rock North and Red Rock have been taken from resource estimates prepared by Ravensgate Minerals Industry Consultants on behalf of White Rock Minerals Ltd and authored by Mr Don Maclean who is a professional geologist with more than 10 years’ experience in resource estimation. Mr Maclean is a Competent Person as defined by the JORC Code and consents to the inclusion in this Presentation of references to this resource estimate in the form and context in which they appear. The gold and silver Resource figures for Guy Bell have been taken from the resource estimate report dated 1 October 2008 prepared by Mining One Pty Ltd on behalf of Rex Minerals Ltd and authored by Dr Chris Gee who is a professional geologist with more than 10 years’ experience in resource estimation. Dr Gee is a Competent Person as defined by the JORC Code and consents to the inclusion in this Presentation of references to this resource estimate in the form and context in which they appear. The Resources figures have not been updated since to comply with the JORC Code 2012 on the basis that the information has not materially changed since it was last reported. The pit optimisation study used a Mineral Resource made up of a combination of Indicated and Inferred Resource blocks. There is a low level of geological confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of Indicated Mineral Resources or that the production target itself will be realised. We have estimated the resources reported in this Presentation in accordance with the Australasian Code for Reporting of Identified Mineral Resources and Ore Reserves 2004 Edition ("JORC Code"), which governs such disclosure by companies listed on the Australian Securities Exchange.

A review of mining1 has advanced the initial design of the mine pits, site layout, waste dumps and mine scheduling. A key element of the current Feasibility Study is to investigate a range of parameters to maximise the economic returns from the Project:- Plant throughputs between 800,000 to 1,200,000 tonnes per annum; Reduced mining and processing costs as a result of this increased throughput; An increased gold equivalent2 production profile up to and exceeding 40,000oz per annum initially, Whilst still retaining an initial 6 to 7 year mine life.
1 Refer to WRM release to the ASX of 20 October 2016 - Initial Mining review demonstrates significant upside potential at Mt Carrington. 2 Gold equivalent production target calculations use the assumptions (gold price, silver price and metal recoveries) provided in Annexure A of the 20 October 2016 ASX Release. The price assumptions are A$1,600/oz for gold and A$22/oz for silver. The formula for gold equivalent calculations is gold produced plus silver produced times 22 divided by 1600 (the A$ price assumptions for silver and gold respectively). White Rock considers that both gold and silver have reasonable potential to be recovered and sold.

CRH Streaming Financing Cost:- a minimum of 40,000 ounces of gold equivalent over a 7-year period (at a minimum of 20% of its annual production). The Financial Metrics in the Scoping Study as a result of this financing are:- Mt Carrington expected to still generate A$54M in free cash flow over its initial 7-year mine life, with a project NPV10 of A$37.4M.
free cash flow is ~A$81M (up 50%) with a project NPV10 of A$53.9M (up 44%). White Rock maintains 100% ownership of the asset. White Rock can advance its exciting zinc-silver VMS Project in Alaska. The proposed gold streaming financing arrangement is non-dilutive to shareholders. White Rock gains a cornerstone strategic partner for the 9+ year journey. WRM joins a stable of other gold investments made by CRH – ASX listed Orinoco, TSX-V listed K92 Mining, TSX-V listed Equitas Resources and TSX-V Sage Gold Inc.

The approach for all reserve and resource calculations is consistent with the definitions and guidelines in the Society of Petroleum Engineers (SPE) 2007 Petroleum Resources Management System (PRMS). The resource estimate methodologies incorporate a range of uncertainty relating to each of the key reservoir input parameters to predict the likely range of outcomes. Cooper Energy has completed its own estimation of reserves and contingent resources based on information provided by the permit Operators Beach Energy Ltd, Senex Ltd and Santos Ltd, and in accordance with the definitions and guidelines in the Society of Petroleum Engineers (SPE) 2007 Petroleum Resources Management System (PRMS). Petroleum Reserves and Contingent Resources are prepared using deterministic and probabilistic
3C estimates may be optimistic due to the effects of arithmetic summation. Totals may not exactly reflect arithmetic addition due to rounding. The information contained in this report regarding the Cooper Energy reserves and contingent resources is based on, and fairly represents, information and supporting documentation reviewed by Mr Andrew Thomas who is a full-time employee of Cooper Energy Limited holding the position of General Manager Exploration & Subsurface, holds a Bachelor of Science (Hons), is a member of the American Association of Petroleum Geologists and the Society of Petroleum Engineers, is qualified in accordance with ASX listing rule 5.41, and has consented to the inclusion of this information in the form and context in which it appears. The Cooper Basin totals comprise the probabilistically aggregated PEL 92 project fields and the arithmetic summation of the Worrior project reserves. Total includes 0.05 MMbbl oil reserves used for field fuel. The Indonesia totals include removal of non-shareable oil (NSO) and comprise the probabilistically aggregated Tangai-Sukananti KSO project fields. Totals are derived by arithmetic summation. In the Otway Basin, reserves for the Casino, Henry and Netherby fields have been assessed by Cooper Energy. The Reserves have been assessed using deterministic and probabilistic methodologies for the Waarre Formation at the Casino, Henry and Netherby fields. This methodology incorporates a range of uncertainty relating to each of the key reservoir input parameters to predict the likely range of outcomes. Cooper Energy undertook the following analytical procedures to estimate the Reserves: independent interpretation of 3D seismic data; analysis of historical production data to assess accessed gas volumes and future production forecasts; review of the Operator’s reservoir and production simulation models to define raw gas recovery consistent with existing processing facilities; and independent probabilistic Monte Carlo statistical calculations to establish the range of recoverable gas. The Otway gas reserves for Casino, Henry and Netherby fields are net of fuel gas. The date of the Casino, Henry and Netherby Reserve Assessment is 27 February 2017. Sole gas field The contingent resource for the Sole field has been re-estimated assuming a two well subsea development plan. Advantages of a two well plan compared to the previous single well development include: increased 2C estimate attributable to accessing previously undeveloped gas; and reduced technical risk and enhanced field redundancy providing increased security of supply to the gas processing and gas sales agreements. Contingent resources for the Sole field were released to the ASX on 26 November 2015. Post-acquisition of the remaining 50% equity in the Sole gas field the following methodologies were used by Cooper Energy to re-calculate the Sole contingent resource estimate: probabilistic simulation modelling for the Kingfish Formation; incorporation of a range of uncertainty relating to each of the key reservoir input parameters to predict the likely range of outcomes; and review of the reservoir and simulation modelling assuming a two well subsea development. The date of the Sole contingent resource assessment is 27 February 2017. Manta gas and oil field Contingent and Prospective Resources have been assessed using deterministic simulation modelling and probabilistic resource estimation for the Intra-Latrobe and Golden Beach Sub-Group in the Manta
used to convert from Sales Gas (PJ) to Oil Equivalent (MMboe). Contingent Resources for the Manta Field have been aggregated by arithmetic summation. The date of the Manta Contingent Resource assessment is 16 July 2015 and the assessment was announced to the ASX on 16 July 2015. Cooper Energy is not aware of any new information or data that materially affects the information provided in that release and all material assumptions and technical parameters underpinning the assessment provided in the announcement continues to apply. Basker gas and oil field. Contingent and Resources have been assessed using deterministic simulation modelling and probabilistic resource estimation for the Intra-Latrobe Sub-Group in the Basker field. This methodology incorporates a range of uncertainty relating to each of the key reservoir input parameters to predict the likely range of outcomes. The conversion factor of 1PJ = 0.172MMboe has been used to convert from Sales Gas (PJ) to Oil Equivalent (MMboe). Contingent Resources for the Basker Field have been aggregated by arithmetic summation. The date of the Basker Contingent Resource assessment is 15 August 2014 and the assessment was announced to the ASX on 18 August 2014. Cooper Energy is not aware of any new information or data that materially affects the information provided in that release and all material assumptions and technical parameters underpinning the assessment provided in the announcement continues to apply.
