Forward Looking Statements
Certain information regarding Erdene ("the Company") contained herein may constitute forward-looking statements within the meaning of applicable securities laws. Forwardlooking statements may include estimates, plans, expectations, opinions, forecasts, projections, guidance or other statements that are not statements of fact. Although the
Company believes that the expectations reflected in such forward-looking statements are reasonable, it can give no assurance that such expectations will prove to have been
correct. The Company cautions that actual performance will be affected by a number of factors, many of which are beyond the Company's control, and that future events and
results may vary substantially from what the Company currently foresees. Factors that could cause actual results to differ materially from those in forward-looking statements
include market prices, exploitation and exploration results, continued availability of capital and financing and general economic, market or business conditions.
All Mineral Resources for Altan Nar reported in this presentation represent estimates as at 19th February, 2015. RungePincockMinarco (“RPM”) have considered the costs,
recoveries and dilutions expected by comparing with other similar deposits in the region and adjusted these by considering the location of the Project and the deposit
characteristics. Mineral Resource grades are reported in accordance with the CIM Standards.
Mineral Resource Estimates for Altan Nar are reported on a dry in-situ basis. Gold equivalent (“AuEq”) values are used in an effort to express the combined value of gold, silver,
lead and zinc as a percentage of gold, and are provided for illustrative purposes only. No allowances have been made for recovery losses that may occur should mining eventually
result. Calculations use metal prices of US $1,200/oz gold, $18/oz silver, and $0.90/lb for lead and zinc.
The Mineral Resource estimates for Altan Nar has been compiled under the supervision of Mr. Jeremy Clark who is a full-time employee of RPM and a Member of the Australian
Institute of Geoscientists. Mr. Clark has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activity that he has
undertaken to qualify as a Qualified Person as defined in the CIM Standards of Disclosure.
Please refer to the NI 43-101 compliant mineral resource report for Altan Nar, dated March 24, 2015, entitled “Altan Nar Gold Project, National Instrument 43-101 Mineral Resource
Technical Report”, available on the Company’s profile at www.sedar.com, as well as the Company’s news release dated March 31, 2015, for further details on the Altan Nar mineral
resource estimate.
Reported drill hole intervals at Altan Nar represent drill intersection widths with most holes drilled at a 45 degree angle. For the Discovery Zone, the orientation of the
mineralization is near vertical and therefore true width is interpreted to be approximately 70% of the reported intervals. For Union North the mineralized zone has an interpreted dip
of 45 degrees therefore true width is close to reported drill hole intervals. All holes in Union North were drilled perpendicular to the trend of mineralization.
All other technical/geologic information contained herein has been reviewed and approved by Michael MacDonald, P.Geo. (Nova Scotia), Director of Exploration for Erdene, who is
the Qualified Person as that term is defined in National Instrument 43-101. All samples have been assayed at SGS Laboratory in Ulaanbaatar, Mongolia. In addition to internal
checks by SGS Laboratory, the Company incorporates a QA/QC sample protocol utilizing prepared standards, blanks and duplicates.
The Company's forward-looking statements are expressly qualified in their entirety by this cautionary statement. The information contained herein is stated as of the current date
and subject to change after that date.
Unless otherwise indicated, all dollar values herein are in C$.

Bayan Khundii Gold Discovery
15
Bayan Khundii Gold Discovery
§  New discovery made by Erdene geologists on 100%
owned licence in July 2015
§  Visible gold observed in multiple locations with no
significant sulphide material present
§  Rock samples returned very high grade gold
§  Detailed sampling and trenching program initiated in
late August
§  Highly anomalous gold values over 1.4 km area
§  Target has not been drill tested
Bayan Khundii is yet another high-quality discovery by the Erdene technical team and is
testimony to the vast untapped mineral potential that exists in southwest Mongolia
