Erdene Announces Significant New Gold Discovery in Southwest Mongolia, Commences Drill Program

HALIFAX, NOVA SCOTIA--(Marketwire - Sept. 7, 2011) - Erdene Resource Development Corp. ("Erdene") (TSX:ERD), is pleased to announce results from an expanded surface exploration program, focused on gold and base metal mineralization, at the Company's 100% owned Tsenkher Nomin property in southwest Mongolia. This program has resulted in the discovery of extensive gold mineralization. A drill rig was mobilized to the property and commenced drilling September 5th to determine the extent of the mineralization.


  • A widely spaced soil survey (400 metres between samples) identified an intense gold-in-soil geochemical anomaly that included two adjacent samples that returned 0.47g/t and 1.4g/t gold

  • Initial prospecting in the area of the gold-in-soil anomaly identified a wide zone of intense, parallel epithermal quartz veining over a 160 metre by 100 metre area

  • Rock chip samples from these veins returned an average grade of 3.4g/t gold from 20 samples, including one sample that returned 19.2g/t gold and 12.5% lead

  • Additional prospecting 400 metres further south resulted in the discovery of gold-bearing epithermal veins over a 160 metre strike length that returned an average grade of 5.2g/t gold from 11 rock chip samples, including one sample that returned 41.3g/t gold and 10.9% lead

Tsenkher Nomin Property

The Tsenkher Nomin property is located in south-western Mongolia discovered, in part, by a regional stream sediment survey that identified a broad polymetallic geochemical anomaly. Previously undocumented old workings, consisting of a series of shallow hand-dug pits, were identified; this area was the focus of the initial exploration program which included geochemical sampling and geophysical surveys (IP and magnetic). This prospect, referred to as Nomin Tal, was the subject of a scout drilling program earlier this year consisting of six drill holes which intersected high grade gold and copper mineralization below the ancient pits, including 0.5 metres of 13.3g/t gold, 3.0% copper and 26g/t silver.

As a result of these encouraging assays, an expanded exploration program was carried out including geological mapping, rock chip sampling and a soil geochemical survey at 400 metre intervals. This expanded exploration program identified a number of significant new discoveries over a large area of the Tsenkher Nomin property including several high grade gold anomalies. The most significant of the new discoveries is a large polymetallic anomaly (gold and lead with lesser zinc and copper) referred to as Altan Nar. The geochemical anomaly at Altan Nar extends over an area approximately 2 kilometres by 3 kilometres. Geochemical results include high grade gold (41.3g/t) from rock chip sampling and wide-spread soil anomalies which include highly anomalous values for gold (up to 1.5g/t) and lead (up to 2.6%).

Altan Nar

The Altan Nar area is located approximately 2.5 kilometres southwest of the Nomin Tal copper-gold prospect. The Altan Nar prospect contains several new polymetallic epithermal discoveries with the two most significant to date referred to as Altan Nar 1 and Altan Nar 2.

Altan Nar 1 contains wide-spread mineralized quartz veins traced over 400 metres along strike and up to 100 metres in width in an area with limited exposure. The area is characterized by widespread massive chalcedony, recrystallized coarse comb, saccharoidal, quartz-carbonate veins and fine comb quartz veinlets. Sphalerite and galena mineralization as well as malachite staining is commonly associated with the quartz veining. A total of 28 rock chip samples were collected from across the Altan Nar 1 prospect with 16 of these samples returning gold values greater than 1g/t with an average of all 28 samples at 2.7g/t gold (range 19.2g/t to 26ppb gold). The Altan Nar 1 samples were also anomalous in silver, lead and zinc. Silver values ranged from less than detection limit (1g/t) to 74g/t (average 11.2g/t); lead values ranged from 205ppm to 12.5% (average 1.02%); and zinc values ranged from 383ppm to 1.59% (average 0.37%). A close-spaced geochemical soil survey (100 metre spacing) has been completed over the Altan Nar 1 area with results pending. Geophysical surveys are currently underway.

Altan Nar 2 is located 400 metres south of Altan Nar 1 and is characterized by polymetallic epithermal quartz veins traced over a 160 metre strike length. Eleven rock chip samples were collected over the 160 metre strike length and all samples returned anomalous gold, silver, lead and zinc values. Gold values ranged from 256ppb to 41.3g/t, with six of the 11 samples returning values greater than 1g/t gold. Silver values ranged from 2g/t to 11g/t (average 9.5g/t). Lead values ranged from 0.4% to 10.9% (average 1.97%), with four of the 11 samples returning values greater than 1% lead. Zinc values ranged from 0.15% to 3.03% (average 1.08%), with five of the 11 samples returning values greater than 1% zinc. Although the mineralization at Altan Nar 2 appears to be associated with narrow quartz veins (less than 1 metre), the area of mineralized quartz veins appears to widen to the north toward Altan Nar 1.

Also of interest are two additional areas (Altan Nar 3 and 4) with anomalous gold, silver, lead and zinc values. Only limited rock chip samples have been taken over these prospects to date. Altan Nar 3 is located approximately 600 metres east of Altan Nar 1 and 2. A single rock chip sample returned 11.2g/t gold, 8g/t silver and 0.25% lead. This sample is within a zone of anomalous soil geochemistry. Altan Nar 4 is located 1.5 kilometres southeast of Altan Nar 1 and four rock chip samples, along a 700 metre strike length, all returned values greater than 1.3g/t gold (range 1.3g/t to 3.8g/t) and averaged 2.7g/t gold. These four samples also averaged 13g/t silver, 1.5% lead and 0.52% zinc.

Preliminary rock chip sampling and geological mapping over the four Altan Nar prospects has identified highly anomalous gold mineralization over a zone covering approximately 2 kilometres by 1 kilometre. The potential for additional discoveries within the area of the larger soil geochemical anomaly (2 by 3 kilometres) at Altan Nar is considered by management to be high.

Nomin Exploration Plans

The initial 400 metre spaced soil geochemical program has been expanded with closer spaced sampling (200 and 100 metre intervals) along with detailed geological mapping and rock chip sampling, particularly in the areas of soil geochemical anomalies, including the Altan Nar area. In addition, a geophysical program (IP and magnetic) is currently underway. Results are expected to be received throughout September. Drilling commenced on September 5th at Nomin Tal and will continue at Altan Nar by mid-September.
