Mongolia Project Update

Altan Nar

During the second quarter, the Company reported its best results to date from drilling at the Altan Nar (Golden Sun) project in southwest Mongolia. These included the highest grade gold interval drilled at Altan Nar with 17.7 g/t gold over 5 m, within 19 m of 5.8 g/t gold, 37 g/t silver and 2.49% combined lead and zinc, intersected in the Discovery Zone ("DZ"), and up to 24 m exceeding 2 g/t gold at the Union North target, located over one kilometer north of the DZ. Click here to read the Company's press release that presents the DZ results, and here to read the Company's press release that presents the Union North results. These near-surface mineralized zones have also been exposed at surface through trenching. The DZ strike length was extended to 450 m and is still open to the northeast and at depth where drilling returned 6 m of 4.8 g/t gold at 235 m. Union North has been tested over a 150 m strike length through trenching and drilling and remains open in all directions.

During the second quarter the Company also completed an expanded surface exploration program, an induced polarization ("IP") geophysical survey, close-spaced infill geochemical soil sampling, and rock chip sampling. Results from this program support the continued expansion of the gold-polymetallic mineralization within the 5.6 km by 1.5 km target area at Altan Nar and has resulted in improved definition of 12 highly prospective targets. Two of these targets, the DZ and Union North, have been shown to host significant near-surface mineralization while the remaining ten targets are relatively un-tested by trenching and drilling. These zones have the potential to significantly expand the areas of known gold-polymetallic mineralization at Altan Nar with further exploration. The Erdene technical group is currently compiling, reviewing and interpreting results of the second quarter 2014 program which will be incorporated in the design of the next exploration phase to commence in the third quarter. Exploration, including delineation and exploration drilling, trenching and expanded geotechnical surveys is expected to continue at Altan Nar during the remainder of 2014 with the goal of establishing a maiden National Instrument 43-101 compliant resource and the identification of further gold, silver, lead and zinc mineralization amenable to open pit development.

Khuvyn Khar Copper Porphyry Project

The 2014 exploration program at the Company's Khuvyn Khar copper project, located 40 km east of the Altan Nar project, has included field evaluation of the seven porphyry copper drill targets identified during the 2013 program and geophysical characterization studies of drill core to provide further definition and confidence in the modelling of potential mineralization at Khuvyn Khar. Geochemical rock chip sampling, vein density mapping, and geophysical modeling completed during the second quarter has resulted in the identification of new, partially buried targets in the western and central portion of the Khuvyn Khar target area. Plans are now being developed for additional work for the remainder of 2014. The ongoing exploration program continues to confirm the potential for copper-rich porphyry style mineralization within the Khuvyn Khar target area. This conclusion is supported by high-grade copper-silver mineralization intersected by Erdene in previous drilling (34 m of 1.34% copper and 9.24 g/t silver).

Regional Exploration

The Company continues to evaluate metal opportunities throughout Mongolia, through both the Teck Alliance and independently, but has largely concentrated in the southwest and predominantly on gold and base metals. This includes the Company's 100% owned Altan Arrow license, located 15 km southeast of the Altan Nar project, where recent trenching confirmed the presence of high-grade gold, with 6 m of 4.5 g/t gold (including 1 m of 16.7 g/t gold) and 1 m of 31.4 g/t gold within epithermal quartz veins and the potential for broader mineralized zones.

Zuun Mod Molybdenum Resource

The Company controls a very large, NI 43-101 compliant molybdenum and copper resource in southwestern Mongolia. Although molybdenum prices have been under downward pressure in recent years, the improving global economy and ongoing shift in China from infrastructure industrialization to urbanization/modernization has resulted in increasing demand for stainless steel of which molybdenum is the third most widely used alloying element. Molybdenum has one of the highest melting temperatures of all the elements, yet unlike most other high-melting point metals, its density is only 25% greater than iron's. Its coefficient of thermal expansion is the lowest of the engineering materials, while its thermal conductivity exceeds all but a handful of elements. As such, it is being used in many key areas in the urbanization and modernization area including high strength steels allowing for weight reduction in automobiles, piping for the oil and gas industry, desalination and sepercritical power plants and in many everyday uses in residential and industrial construction. This increasing demand, in the face of recent production decreases globally, has resulted in a rebounding price for molybdenum in recent months with between 30% and 50% increases over the low price reached in 2012. The Zuun Mod project, based on its location relative to the China market, it's proximity to infrastructure, its very large resource, and its potential for further exploration success represents an exceptional development opportunity as the Molybdenum markets rebound.

Teck Alliance

In April 2013 the Company formed an Alliance with Teck Resources Ltd. ("Teck") under which Teck would subscribe for up to $3 million of the Company's equity through subscriptions or 19.9% of the outstanding shares of Erdene, whichever occurs first. Share purchases are priced at the then current market plus 10%. Teck has participated in three subscriptions totaling $1.5M invested to date and currently owns 12.2% of the outstanding shares of Erdene. Erdene is committing 85% of the proceeds of the Teck private placements to exploration work to be directed by a technical committee, with the remaining 15% to be used for general corporate purposes. Once Erdene has spent the proceeds from the Teck financings on the initial program, Teck will have the option to acquire up to a 75% interest in designated projects through a two-stage option process by funding exploration expenditures of up to $10 million on the Company's Khuvyn Khar project and up to $5 million on each of the other existing or acquired projects (excluding Altan Nar and Zuun Mod) so designated within the Trans Altai project area of southwest Mongolia. Projects are currently underway in the Trans Altai area on regional properties and the Khuvyn Khar copper project.

Mongolia Update

In an effort to improve the investment climate for foreign investors, the Mongolian government in October 2013 passed, with 83% parliamentary approval, a new Foreign Investment Law that eases restrictions on foreign investors and offers long-term tax stabilization contracts. In January 2014, the Mongolian government announced the passing of an amendment to the Minerals Law that reduced the royalty for gold from 10% to 2.5% under the condition that producers sell their output to the Mongolian central bank. In addition to these positive legislative changes, it is anticipated that Phase II funding for Rio Tinto's Oyu Tolgoi copper-gold project will be approved in 2014, allowing it to advance to underground development. It is expected that the approval of the underground phase of this world-class project will be a positive stimulus for the mineral exploration and mining sector in Mongolia.

Significant Cost-Saving Initiatives

During the AGM, the Company presented details of significant cost-saving initiatives undertaken during the past year. At the 2013 AGM, the cost-saving target presented was a minimum 43% reduction in G&A during fiscal 2013. That target was exceeded with cash administration costs decreasing by $771,220, or 53%, compared to the prior year. This significant cost saving is evidence of management's continued focus on the reduction of overhead and administrative expenses and the increase of equity-based compensation in lieu of cash. In 2013, administrative expenses totaled $939,455 (including $225,626 in non-cash stock based compensation), compared to $1,678,298 in 2012 (including $186,559 in non-cash stock based compensation).

Options

Following the AGM, the Company's board granted an aggregate of 1,090,000 incentive stock options to an aggregate of 21 directors, officers and employees of and consultants to the Company. The options are exercisable for 5 years at an exercise price of $0.16.
