2. Certain information regarding Erdene ("the Company") contained herein may constitute forward-looking statements within the meaning of applicable securities laws. Forward-
looking 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 have 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.
Reported drill hole intervals at Bayan Khundii represent drill intersection widths from holes drilled at a 45 to 60 degree angle. The Bayan Khundii mineralization is moderately
dipping (approximately 40 to 50 degrees) perpendicular to the drill hole angle.
Results for the metallurgical test programs summarized in this release were reviewed and approved by Andrew Kelly, P.Eng., of Blue Coast Research Ltd., a Qualified Person for
the purpose of National Instrument 43-101. 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 drill result 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 and
blanks. All metallurgical testing and analysis was carried out by Blue Coast Research Ltd. at their facility in Parksville, British Columbia.
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$.

§ During 2Q-2016, Russia (+38.4t), China (+25.9t) and Kazakhstan (+9.8t)
were the top three driving forces behind central bank purchases
§ China remains the world’s #1 gold producer (490t; 17 Moz), with Russia
at #3 (242t; 8.5 Moz), and Uzbekistan at #9 (103t; 3.6 Moz)
§ To feed rising local demand, international M&A activity from Chinese
gold companies is rising, quadrupling to $483 M in 2015
§ China recently established the $16-Billion Silk Road Gold Fund to
facilitate increasing its gold holdings
§ China’s top gold producer, China National Gold Group Corp., recently
signed an agreement with Russia’s top gold producer, Polyus Gold, to
strengthen ties in regional gold exploration

Development of Mongolia’s Gold Industry
1995 to 1999
§ Pre 1990 - Limited commercial gold operations
§ 1995 - Gold production hits 125,000 ounces, 100% increase from 1994; sourced
from 75, state/privately-owned placer mines in North-Central and SW Mongolia,
equating to approximately US$25 M in gold exports
§ 1998 - Despite low gold prices ($290/oz), gold production spikes 150% from 1995
levels, hitting 314,000 ounces, with a growing number of low-cost placer gold mines
§ 9-Sept, 1998 - Headline in Mongolian National News Agency: Gold extraction up
10 times in the last 6 years, Mongolia expected to extract 20-25 tons of gold in 2003
§ Nov 1998 - Government, backed by IMF, imposes 10% VAT on sales/export of gold,
despite strong opposition from industry
§ 1999 - Some foreign gold mining companies exit, and local placer miners remain,
selling output to Mongolian Central Bank (production holds steady at 320,000 oz).
Two foreign companies remain; Cascadia Mining Inc. and Java Gold Corp.

31. Why Invest in ERD?
31
Early-In Opportunity
‒ Developing a new gold district through greenfield discovery
‒ Early in exploration to development value curve
‒ Low point in commodity cycle = low valuations
Ownership
‒ 100% interest in Projects
Growth Potential
‒ Limited drilling to date
‒ All targets open for expansion over large areas; 1.7km at Bayan
Khundii and 5.6 km at Altan Nar
High-Grade & Near Surface
‒ Very high grades
‒ Mineralized zones steeply dipping, exposed at surface
Excellent Metallurgy
‒ 99% gold recovery for high-grade Bayan Khundii
‒ 88 to 92% for Low Grade Bayan Khundii & Altan Nar (DZN)
Experience
‒ Very experienced management team; in Mongolia since the
mid-1990’s
Location & Infrastructure
‒ Region receiving rapid rail & road upgrades
‒ Next door to world’s second largest gold consumption region and
largest gold producer
