Mr. Clark has guidance or other statements that are not statements of TECHNICAL REPORTS sufficient experience that is relevant to the style of fact. Although the Company believes that the mineralisation and type of deposit under consideration For the Bayan Khundii project, please refer to the expectations reflected in such forward-looking and to the activity that he has undertaken to qualify as a Company’s National Instrument 43-101 technical report, statements are reasonable, it can give no assurance that available on the Company’s profile at www.sedar.com. Qualified Person as defined in the CIM Standards of such expectations will prove to have been correct. The Disclosure. There is no resource estimate included in the report. Company cautions that actual performance will be affected by a number of factors, many of which are For the Altan Nar project, please refer to the NI 43-101 beyond the Company's control, and that future events SAMPLE PROTOCOL compliant mineral resource report for Altan Nar, dated and results may vary substantially from what the All samples have been assayed at SGS Laboratory in March 24, 2015, entitled “Altan Nar Gold Project, Company currently foresees. Factors that could cause Ulaanbaatar, Mongolia. In addition to internal checks by National Instrument 43-101 Mineral Resource Technical actual results to differ materially from those in forward- SGS Laboratory, the Company incorporates a QA/QC Report”, Company’s available on the profile at looking statements include market prices, exploitation sample protocol utilizing prepared standards and blanks. www.sedar.com, as well as the Company’s news release and exploration results, continued availability of capital Erdene’s sampling protocol for drill core consisted of dated March 31, 2015, for further details on the Altan Nar and financing and general economic, market or business collection of samples over 1 metre or 2 metre intervals mineral resource estimate. All Mineral Resources for conditions. (depending on the lithology and style of mineralization) Altan Nar reported in this presentation represent over the entire length of the drill hole, excluding minor estimates as at 19th February, 2015. RungePincock- The Company's forward-looking statements are post-mineral lithologies and un-mineralized granitoids. Minarco (“RPM”) have considered the costs, recoveries expressly qualified in their entirety by this cautionary Sample intervals were based on meterage, not and dilutions expected by comparing with other similar statement. The information contained herein is stated as geological controls or mineralization. All drill core was cut deposits in the region and adjusted these by considering of the current date and subject to change after that date. in half with a diamond saw, with half of the core placed in the location of the Project and the deposit characteristics. Unless otherwise indicated, all dollar values herein sample bags and the remaining half securely retained in Mineral Resource grades are reported in accordance core boxes at Erdene’s Bayan Khundii exploration camp. are in C$. with the CIM Standards. All samples were organized into batches of 20 samples Mineral Resource Estimates for Altan Nar are reported including a commercially prepared standard and blank. DRILLHOLE INTERVALS on a dry in-situ basis. Gold equivalent (“AuEq”) values Sample batches were periodically shipped directly to Reported intervals in this presentation are not true width. are used in an effort to express the combined value of SGS in Ulaanbaatar via Erdene’s logistical contractor, At this time, there is insufficient data with respect to the gold, silver, lead and zinc as a percentage of gold, and Monrud Co. Ltd. shape of the mineralized system to calculate true are provided for illustrative purposes only. No orientations in space. At the Company’s Bayan Khundii All metallurgical testing and analysis was carried out by allowances have been made for recovery losses that project, reported intervals represent drill intersection Blue Coast Research Ltd. at their facility in Parksville, may occur should mining eventually result.

The Bayan Khundii $0.90/lb for lead and zinc. mineralization is moderately dipping (approximately 40 to 50 degrees), approximately perpendicular to the drill hole QUALIFIED PERSONS angle. Michael MacDonald, P.Geo. (Nova Scotia), Vice Reported drill hole intervals at the Company’s Altan Nar President of Exploration for Erdene, is the Qualified project represent drill intersection widths with most holes Person as that term is defined in National Instrument drilled at a 45 degree angle. For the Discovery Zone, the 43-101 and has reviewed and approved the technical information contained in this presentation. orientation of the mineralization is near vertical and Results for the metallurgical test programs summarized therefore true width is interpreted to be approximately in this release were reviewed and approved by Andrew 70% of the reported intervals.
