OUTLINE DisclaimerThis presentation has been prepared by Marmota Limited (“MEU”). The information contained in this presentation is a professional opinion only and is given in good faith. Certain information in this document has been derived from third parties and though MEU has no reason to believe that it is not accurate, reliable or complete, it has not been independently audited or verified by MEU. Any forward-looking statements included in this document involve subjective judgement and analysis and are subject to uncertainties, risks and contingencies, many of which are outside the control of, and may be unknown to, MEU. In particular they refer only to the date of this document they assume the success of MEU’s strategies, and they are subject to significant regulatory, business, competitive and economic risks and uncertainties. Actual future events may vary materially from those in the forward looking statements. Recipients of this document are cautioned not to place undue reliance on such forwardlooking statements. MEU makes no representation or warranty as to the accuracy, reliability or completeness of information in this document and does not take responsibility for updating any information or correcting any error or omission which may become apparent after this document has been issued. To the extent permitted by law, MEU and its officers, employees, related corporations and agents, disclaim all liability, whether direct, indirect or consequential for any loss or damage arising out of, or in connection with, any use or reliance on this presentation or information.
Cautionary StatementThe estimates of exploration target sizes mentioned above should not be misunderstood or misconstrued as estimates of Mineral Resources. The estimates of exploration target sizes are conceptual in nature and there has been insufficient results received from drilling completed to date to estimate a Mineral Resource compliant with the JORC Code (2012) guidelines. Furthermore, it is uncertain if further exploration will result in the determination of a Mineral Resource.
Forward Looking StatementThis presentation may contain forward looking statements that are subject to risk factors which are based on MEU’s expectations relating to future events. Forward-looking statements are subject to risks, uncertainties and other factors, many of which are outside the control of MEU, which could cause actual results to differ materially from such statements. MEU makes no undertaking to update or revise the forward-looking statements made in this report to reflect events or circumstances aver the date of this release.
Competent Persons StatementInformation in this presentation relating to Exploration Results and Mineral Resources is based on information compiled by Dr Kevin Wills, acting Managing Director of MEU, who is a Fellow of the Australasian Institute of Mining and Metallurgy. He has sufficient experience which is relevant to the styles of mineralisation and types of deposits under consideration and to the activities being undertaken to qualify as a Competent Person as defined in the 2012 Edition of the “Australasian Code of Reporting of Exploration Results, Mineral Resources and Ore Reserves.” Dr Wills consents to the inclusion in this report of the matters based on his information in the form and context in which it appears.

Aurora Tank ProspectDRILLING RESULTS
Best downhole gold results at Goshawk Prospect at Aurora Tank.
• Anomalous zone originally defined by calcrete sampling in the late 1990s
• Early drilling by Minotaur located isolated results up to 1m @ 1-2g/t Au
• Drilling by Apollo (in JV with Marmota) in 2014-2015 achieved an intersection of 4m @ 5g/t Au
• Drilling by Marmota in September 2016 led to a number of significant intersections with up to 34g/t Au over 1mF

• Best drill results are in an overall area with surface calcrete copper anomalies
• No detailed direct relationship between calcrete copper anomalies and drilling results
• Calcrete copper anomalies present over shallow copper anomalous bedrock
• Good grades at depth may not be reflected in surface calcrete copper anomalism

The polygonal Exploration Target is therefore based on actual recent drill hole intersections and is defined as between 1.7 and 3.1 million tonnes at a grade of 0.8% to 1.2% copper. This target is partly conceptual in nature, there has been insufficient exploration to estimate a Mineral Resource and it is uncertain that further exploration will result in the estimation of a Mineral Resource. Sectional Estimation Since the previous drill holes can be projected onto five straight lines with holes at approximately 50 metre centres, it is also possible to carry out a type of sectional estimate of the size and grade of intersected mineralisation. This has been carried out and the results presented in Figure 9 and Table 2. This is not a normal sectional estimate where all sections are parallel and mineralisation is projected half way to the adjacent section. Instead here, a lateral projection distance of either 25 or 50 metres either side of the section has been used. These distances are thought to be reasonable considering the on section correlations, intersection lengths and style of mineralisation. However, this again creates sufficient uncertainty to disallow classification as an Inferred Resource. The five sections were grade contoured as shown on Figure 9. This process allows perimeters to be drawn at different cut-off grades and to be referenced as shown on Figure 9. Tonnage of mineralisation has been estimated by the product of perimeter area, lateral projection length and a
