Bayan Khundii Exploration Program Q2-2016

The Q2-2016 Bayan Khundii exploration program will include 3,500 m of diamond drilling, approximately 900 soil samples over a 7.6 km by 3 km area, 35.4 line km of gradient IP geophysical surveys, 33 line km of dipole-dipole geophysical surveys, 550 m of trenching and sampling within a 2 km by 2 km area, and mineralogical studies. The majority of this work is complete with the exception of drilling; approximately 1,700 m of drilling remains in the program. Results for 1,012 m (7 holes) are being released today and approximately 700 m of drill sample material is currently being analyzed, with all results anticipated during Q2-2016. The drilling program was designed to test the strike and vertical extent of the high-grade gold mineralization discovered in Q4-2015 (previous drilling tested to less than 50 m depth). The first seven reported holes were drilled to depths of 50 to 232 m or approximately 35 to 150 m vertically. All holes are drilled perpendicular to the interpreted dip of the mineralized zones. In addition, various technical studies in support of future scoping/feasibility-level studies and a mining license application, including hydro-geological, archaeological, paleontological, and environmental base line studies, have commenced on both Bayan Khundii and the Company's Altan Nar gold-polymetallic project located 20 km to the northwest.

The following key technical observations have been made from the exploration program to date:

  • High grade gold zones within the Striker Zone can be very wide, grading in excess of 5 g/t gold and greater than 50 m in width;
  • Based on the drilling and surface sampling completed to date, the entire target area has a pervasive low-grade gold mineralization averaging greater than 0.1 g/t gold (excluding all zones with greater than 1 g/t gold);
  • Visible gold mineralization has been observed in newly completed trenches and within unreported drill holes on the western extension of the Striker Zone, from surface to depths up to 116 m;
  • Based on mapped alteration and visible gold observed in the western-most trenches and drill holes, it indicates a minimum strike length on the Striker zone of approximately 200 m;
  • The near-surface, eastern extension of the Striker Zone (BKD-23 to 25) has been partially eroded or structurally displaced, based on an observed unconformity with younger sediments and volcanics. Drilling in the coming weeks will further test the down-dip extension in this area;
  • The alteration and mineralization continues to the north of Striker Zone under the younger sediments and volcanics as evidenced by hole BKD-16 (83 m of 0.59 g/t);
  • Trenching has uncovered several new areas of visible gold southwest of the area drilled (west of Gold Hill);
  • Geophysics has established many targets within the Bayan Khundii project area (2 km by 2 km) and also outlined significant anomalies to the north where silica caps have been identified with similar geophysical signatures;
  • Undrilled areas between Westridge and Gold Hill have strong gold geochemical and geophysical anomalism;
  • Intense chargeability and resistivity anomalies (similar to those recognized at Striker and Gold Hill) are present at the Northeast and Northeast Extension zones located, respectively, 700 m and 1.2 km to the northeast; and
  • Trenching and mapping within the Northeast zone has confirmed the same intensity of alteration with associated anomalous gold mineralization supporting a large interpreted northeast-trending zone of alteration and gold mineralization.

Geology

Bayan Khundii is a low sulfidation epithermal gold system with all of the primary lithologies (volcanic tuff and andesite) pervasively altered by multi-stage, locally intense, silica and sericite alteration. The locally intense silica-sericite alteration (SS2) overprints the pervasive silica sericite alteration (SS1) and commonly forms selvages (halos) around quartz veins, fractures, and hematite/specularite veinlets, as well as selvages surrounding disseminated hematite and other inclusions. Extensive hypogene hematite and specularite mineralization occurs as veinlets, mineralized fractures, locally disseminated, and infilling of breccia zones, including common hematite-quartz breccias. Quartz veins and breccias occur within all altered lithologies and include comb textured quartz, saccharoidal (sugary) quartz, recrystallized quartz (intensely silica altered) as well as chalcedonic quartz. The gold mineralization is associated with quartz veins, quartz breccias, within hematite-specularite veins and fractures, within altered host rocks including along margins (alteration selvages) of quartz veins and disseminated within the altered host rocks, often, but not always, associated with disseminated hematite-specularite mineralization. Gold grades within the host rocks, excluding the greater than 1 g/t material, average 0.1 to 0.2 g/t gold. The recent drilling supports much wider zones of gold mineralization than previously recognized, ranging from previously untested gold mineralization north of the Striker zone with 83 m of 0.59 g/t gold in hole BKD-16, to the high grade intersection in hole BKD-17. Gold mineralization is generally observed to be fine grained.

Future Plans and Results

The current drill program will include continued testing of the Striker Zone as well as Gold Hill, Westridge, Stockwork and now the newly defined Northeast Zone. It is anticipated that this phase of the Bayan Khundii exploration program will be completed in June 2016 with all results received by the end of Q2 or early Q3. On completion of the program the Erdene technical team will be interpreting all results and establishing plans for the next phase of exploration with a follow-up drill program anticipated in Q3-2016.

About the Bayan Khundii Gold Project

In Q2-2015, Erdene conducted an initial exploration program on the southern portion of the Company's 100%-owned Khundii license. This reconnaissance work led to the discovery of the Bayan Khundii ('Rich Valley') gold prospect, located 20 km southeast of the Company's flagship Altan Nar gold-polymetallic project. Subsequently, gold mineralization at Bayan Khundii has been identified in three separate prospect areas over a 1.7 km trend, with detailed exploration only taking place over a 475 m by 300 m zone in the southwest prospect area, where the Company's Q4-2015 drill program (totaling 695 m) was completed. Visible gold was observed in 10 of the 15 initial drill holes and results included several high-grade intersections within a series of parallel structures exposed at surface. Results included up to 35 m of 5.9 g/t gold in hole BKD-10 (including 12 m of 16.2 g/t gold) from surface to the bottom of the hole. The details of that drill program can be found in Erdene's December 14, 2015 news release (click here for link).

Initial independent metallurgical test work, completed by Erdene in February 2016, indicates the gold mineralization at Bayan Khundii is very amenable to conventional processing techniques involving a combination of gravity and cyanide leach of gravity tails, yielding 99% gold recovery for the high-grade composite sample (24.9 g/t gold) and 92% gold recovery for the low-grade composite sample (0.7 g/t gold). Blue Coast Research Ltd. of Parksville, British Columbia, carried out the metallurgical testing program, the details of which can be found in Erdene's February 16, 2016 news release (click here for link).

Qualified Person and Sample Protocol

Michael MacDonald, P.Geo. (Nova Scotia), Director of Exploration for Erdene, is the Qualified Person as that term is defined in National Instrument 43-101 and has reviewed and approved the technical information contained in this news release. 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 and blanks.

Erdene's sampling protocol for drill core consisted of collection of samples over 1 m or 2 m intervals (depending on the lithology and style of mineralization) over the entire length of the drill hole, excluding minor post-mineral lithologies and un-mineralized granitoids. Sample intervals were based on meterage, not geological controls or mineralization. All drill core was cut in half with a diamond saw, with half of the core placed in sample bags and the remaining half securely retained in core boxes at the Company's Bayan Khundii exploration camp. All samples were organized into batches of 20 samples including two commercially prepared standards and blanks. Sample batches were periodically shipped directly to SGS in Ulaanbaatar via Erdene's logistical contractor, Monrud Co. Ltd.
