Erdene Continues to Expand High-Grade Zones at Bayan Khundii, Including Most Significant Intersection to Date, 65 Metres of 6.3 g/t Gold, Including 12 Metres of 29 g/t Gold

HALIFAX, NOVA SCOTIA--(Marketwired - Nov. 28, 2016) - Erdene Resource Development Corp. (TSX:ERD) ("Erdene" or "Company") is pleased to report the fourth batch of drill results from its Q3/Q4 drill campaign at its 100%-owned Bayan Khundii Gold Project ("Bayan Khundii") in southwest Mongolia.

"Today's results further support our belief that Bayan Khundii represents one of the most prospective new high-grade, near-surface gold discoveries in the industry today. Our drill program continues to push the boundaries of the mineralized system at depth and along strike, with today's results including the widest, high-grade intercepts we have witnessed to date," said Peter Akerley, Erdene's President and CEO. "We recently completed a series of drill holes on our two adjacent gold projects within the larger gold district, and have now returned to Bayan Khundii to test new areas for expansion north of the initial discovery. These holes will test targets in the area surrounding hole BKD-60, a strongly mineralized step-out hole that was announced in October."

Highlights (see attached plan maps and cross-sections for reference)

• Drilling continues to extend the boundaries of gold mineralization at Bayan Khundii with several high-grade gold intersections over wide intervals with six of the 13 reported holes ending in gold mineralization
• Multiple gold-bearing structures are now being defined at Bayan Khundii, including Striker Zone, the most extensively explored zone
• Deep Striker

Discussion of Drill Results

Striker Zone - Extension at Depth

Three holes, BKD-77 to BKD-79, were drilled along the southern boundary of the Striker Zone, targeting extensions of mineralization at depth. As shown in Table 1 above, all three holes returned high-grade gold mineralization to depths of up to 136 m. Hole BKD-77 returned 65 m of 6.3 g/t gold between 71 m and 136 m depth and contained very high-grade intervals, including up to 306 g/t gold over 1 m at 111 m depth. All three holes have successfully expanded the southern boundary of the Striker Zone, which remains open in all directions. Drill hole locations are shown on the attached maps.

Striker Zone - Northern Expansion

A new gold zone, located north of and parallel to the Striker Zone, was discovered in mid-2016, and has been further defined with today's results from three drill holes, BKD-82, -83 and -86. These holes were drilled to test continuity of the new zone along strike to the northwest and southeast of the original discovery. As shown in Table 1, all three holes returned high-grade gold mineralization, including 18 m of 7.1 g/t gold (BKD-86) and 17 m of 4.5 g/t gold (BKD-83), with all holes ending in gold mineralization.

Striker Zone - Continuity of High-Grade Zone

Seven holes were drilled within the Striker Zone to test continuity of the high-grade mineralization, including an extension of hole BKD-27. The new holes include BKD-76, -80, -81, -84, -85 and -87. BKD-27 was extended from 85 to 134 m and returned 25 m (109 to 134 m) of 2.4 g/t gold. The fact that this hole ended in gold mineralization confirms the potential for additional mineralization at depth. Drilling within the Striker Zone continues to deliver significant results, with BKD-84 returning 36.7 m of 5.0 g/t gold, including 21 m of 8.3 g/t gold (see Table 1).

All holes drilled to date within the Striker Zone have intersected anomalous gold mineralization. Drill hole spacing generally ranges from 20 m to 50 m over a strike length of 250 m and a down-dip extension of up to 150 m has been established. Wider spaced holes have returned mineralization over a strike length of approximately 400 m and depths up to 200 m vertically. The majority of holes have been orientated perpendicular to the mineralized zones at 30 degrees to the NNE. The zones remains open in all directions and multiple sub-parallel zones are being drilled adjacent to the Striker Zone over a width of approximately 600 m.

Bayan Khundii Regional; Step-Out Drilling

On November 25, 2016, the Company mobilized a drill rig to test a target area approximately 200 m north of the Striker Zone, surrounding the successful step-out hole BKD-60. Results from a series of drill holes in this area are anticipated to be reported early in Q1-2017.

The decision to focus drilling in this area follows very encouraging results from BKD-60 reported on October 18, 2016 that tested a geophysical target beneath younger Cretaceous cover rocks. Hole BKD-60, drilled 170 m north of Striker, returned a very wide intersection of gold mineralization starting immediately below 20 m of Cretaceous cover and averaged 1.3 g/t gold over 123 m, that included 68 m of 2.0 g/t gold (including 30 m of 3.0 g/t gold) near the top of the hole (click here to see October 18 press release). Visible gold was observed in multiple locations, particularly between 29 and 59 m, but continued locally to a depth of 117 m. This hole suggests that significant gold mineralization continues beyond the Striker Zone under the younger Cretaceous units that lie between the main exposed area of mineralization in southwest Bayan Khundii (includes Striker Zone) and the Northeast Zone, located 750 m to the northeast, demonstrating the strong potential for expansion gold mineralization within this area. The prospectivety of this area is strengthened by geophysical surveys (strong induced polarization resistivity response typical of Striker Zone) that suggest an extensive zone of alteration continues at depth to the north and west, beneath the younger Cretaceous units, suggesting that Bayan Khundii's epithermal system may be more widespread than the main exposed areas at surface.

Background on Bayan Khundii Gold Project

In Q2-2015, Erdene conducted an initial exploration program on the southern portion of the Company's 100%-owned Khundii exploration license in southwest Mongolia. This reconnaissance work led to the discovery of the Bayan Khundii, low sulphidation epithermal gold prospect. Gold mineralization at Bayan Khundii has been identified over a 1.7 km trend, with detailed exploration only taking place over a 500 m by 350 m zone in the southwest portion of the prospect area, where the Company's drill programs have focused (includes Striker Zone). Visible gold was observed in multiple drill holes, and results include several high-grade intersections within a series of parallel structures exposed at surface. Results include:

(2)	End of hole

In Q1-2016, the Company concluded preliminary metallurgical test work at Bayan Khundii, indicating that gravity concentration and cyanidation of the gravity tails yield very good overall gold recoveries for both high-grade and low-grade composites: 99% gold recovery from the high-grade composite (24.9 g/t gold), and 92% gold recovery from the low-grade composite (0.7 g/t gold).

The license has a 2% net smelter returns royalty ("NSR Royalty") in favour of Sandstorm Gold Ltd. with a buy-back option to reduce the NSR Royalty to 1%.
