Erdene Announces Resource Estimate for the High-Grade Khundii Gold Project

18.09.2018  |  GlobeNewswire

HALIFAX, Sept. 18, 2018 - Erdene Resource Development Corp. (TSX:ERD) ("Erdene" or "Company"), is pleased to announce the Mineral Resource estimate for its 100%-owned Khundii Gold Project in southwest Mongolia, prepared by RPMGlobal in accordance with the definition standards of National Instrument 43-101 (“NI 43-101”).

Khundii Gold District


High-Grade and Near-Surface


Significant Exploration Upside Along Mineralized Trend


The Khundii Gold Project includes the Company’s high-grade Bayan Khundii and Altan Nar deposits, located 16 kilometres apart. Today’s announcement includes the Maiden Mineral Resource estimate for the Bayan Khundii deposit and incorporates the significant increase in the NI 43-101 Mineral Resource for the Altan Nar deposit reported by the Company in May 2018. These deposits are shallow and high-grade, outcropping and located within the newly discovered Khundii Gold District.

Highlights (see attached figures for reference)

• Khundii Gold project total Mineral Resource:

  • 751,000 ounces gold at an average grade of 2.3 g/t gold, Measured and Indicated; and,
  • 291,000 ounces gold at an average grade of 1.8 g/t gold, Inferred.

• At a higher cut-off grade of 1.4 g/t gold, the Khundii Gold Project contains:

  • 642,000 ounces gold at an average grade of 3.7 g/t gold, Measured and Indicated, including, 357,000 ounces gold at an average grade of 5.2 g/t gold at the Bayan Khundii deposit.

• Including precious and base metals, the Khundii Gold Project includes:

  • 886,000 ounces gold equivalent (“AuEq”) at an average grade of 2.7 g/t AuEq, Measured and Indicated; and
  • 382,000 ounces AuEq at an average grade of 2.3 g/t AuEq, Inferred.

• Work has commenced on the Preliminary Economic Assessment for the Khundii Gold Project, expected to be announced in Q4-2018

“With the results of the maiden Bayan Khundii resource estimate, we have met our initial resource target for the Khundii Gold Project at grades significantly higher than the global average of producing open pit gold mines,” said Peter Akerley, Erdene’s President and CEO. “The Bayan Khundii and Altan Nar deposits provide synergies for our Company and represent a compelling development opportunity given their high-grades, proximity to surface and favorable metallurgy. We will incorporate these two resource estimates into a Preliminary Economic Assessment for the Khundii Gold Project by year-end and expect to submit mining license applications for both deposits in early 2019. At the same time, we continue our regional exploration program with drilling currently underway testing multiple targets, designed to expand current resources and discover new deposits in this newly discovered gold district.”

A supporting NI 43-101 Technical Report will be filed on SEDAR at www.sedar.com within 45 days of this release.

Overview of Mineral Resource Estimate

Bayan Khundii is located 16 kilometres southeast of Erdene’s Altan Nar high-grade gold-polymetallic deposit, where the Company announced a significant increase to the mineral resource on May 10, 2018 (click to read news release). The two resource estimates are considered a single project (Khundii Gold Project) for future economic and technical development studies, and are discussed herein as the Khundii Gold Project Mineral Resource estimate (Table 1).

The Bayan Khundii Maiden Mineral Resource estimate (“Mineral Resource”) was prepared in accordance with NI 43-101 by RPMGlobal Asia Limited (“RPM”) and is dated effective September 12, 2018. The reported Mineral Resource (Table 2) is based on information provided to RPM by Erdene and verified where possible by RPM. All statistical analysis and mineral resource estimations were carried out by RPM. A final NI 43-101 Mineral Resource estimate and Technical Report will be filed on SEDAR within 45 days. The Mineral Resource incorporates 255 diamond drill holes totaling 42,656 metres, completed between Q4-2015 and Q2-2018. The Mineral Resource is contained within a near-surface, shallow-dipping and strongly mineralized system (intercepts up to 2,200 g/t gold as previously reported) that extends over an area of 1.2 kilometres (NE-SW) and 200 to 400 metres (NW-SE). Grade capping for the purposes of the Bayan Khundii deposit resource estimate averaged 51 g/t gold for high-grade domains (range from 8 g/t to 250 g/t gold) and a maximum of 1.5 g/t gold for the low and medium grade domains.

RPM estimated the Khundii Gold Project Mineral Resource at a number of gold cut-offs, however, RPM recommends reporting the Bayan Khundii Mineral Resource at a 0.6 g/t gold cut-off and the Altan Nar Mineral Resource a 0.7 g/t AuEq above a pit and 1.4 g/t AuEq below the same pit shell. A sensitivity analysis of the grade and tonnage relationships at cut-off grades is shown in the Tables below.

Notes:
1. The Statement of Estimates of Mineral Resources has 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.
2. All Mineral Resources figures reported in the table above represent estimates based on drilling completed up to June 27, 2018. Mineral Resource estimates are not precise calculations, being dependent on the interpretation of limited information on the location, shape and continuity of the occurrence and on the available sampling results. The totals contained in the above table have been rounded to reflect the relative uncertainty of the estimate. Rounding may cause some computational discrepancies.
3. Mineral Resources are reported on a dry in-situ basis.
4. The Mineral Resources is reported at a 0.6 g/t Au cut-off. Cut-off parameters were selected based on an RPM internal cut-off calculator, which indicated that a break-even cut-off grade of 0.6 g/t Au, assuming an open cut mining method, a gold price of USD $1500 per ounce, an open mining cost of USD $6 per tonne and a processing cost of USD $20 per tonne milled and processing recovery of 95% Au.
5. Mineral Resources referred to above, have not been subject to detailed economic analysis and therefore, have not been demonstrated to have actual economic viability.

A detailed Mineral Resource estimate for the Altan Nar gold-polymetallic project can be seen below in Table 3. For further details on the Mineral Resource estimate please see the Company’s May 10, 2018 news release (click here).

Background on the Khundii Gold Project

Erdene’s deposits are located in the Edren Terrane, within the Central Asian Orogenic Belt, host to some of the world’s largest gold and copper-gold deposits. Although epithermal gold and porphyry copper-gold deposits are well documented across the border in China and along the Belt’s westward trend, exploration in Mongolia was limited until the mid-1990’s, when the country returned to democracy and opened its’ doors to foreign exploration. Exploration since that time in southeast Mongolia led to the discovery of the world-class Oyu Tolgoi gold-copper deposit. Erdene has been the leader in exploration in Mongolia’s southwest over the past decade and is responsible for the discovery of the Khundii Gold District. The Khundii Gold District is comprised of multiple high-grade gold and base metal prospects, two of which are being considered for development: Bayan Khundii and Altan Nar. In addition, the company discovered and defined a large molybdenum-copper resource on the 100% owned, Zuun Mod project, 40 kilometres to the east.

Over the past two years, drilling at the Altan Nar and Bayan Khundii projects has revealed very high gold grades, including intercepts up to 2,200 g/t gold over 1 metre within 14 metres of 158 g/t gold at Bayan Khundii, and intercepts up to 101 g/t gold over 1 metre within 20 metres of 10.3 g/t gold at Altan Nar. Outside of these two deposits, which will be the focus of a Preliminary Economic Assessment study in Q4-2018, the Company continues its regional, district-scale exploration program. The broader district, although still in its infancy, hosts the full spectrum of arc-related base and precious metal systems, including copper-gold porphyries, intermediate sulphidation / carbonate base metal gold deposits, and low sulphidation epithermal gold and gold-silver systems.
