Dundee Precious Metals Inc. (TSX:DPM)(TSX:DPM.WT.A) ("DPM" or "the Company") is pleased to report the favourable technical results outlined in its preliminary economic assessment ("PEA") of the potential underground expansion project (the "Project") at its Kapan Mine in Armenia.
Highlights of PEA
- Planned expansion of the Kapan Mine to 1 million tonnes per annum ("Mtpa") based on December 31, 2013 Indicated and Inferred Mineral Resources;
- Reviewed refurbishment of existing mill equipment plus modest additional capital to restore mill to its prior 1 Mtpa operating rate;

"We are pleased with the results of the new PEA on our Kapan underground expansion project," stated Rick Howes, President and CEO. "An underground expansion could showcase the mine's true potential and create value for our shareholders. The study shows that the incremental capital required is quite small and it results in a significant increase in net cashflow to the business and a very high return project," he added.
Mineral Resource and Life of Mine Mineral Inventory
Mineral Resources and LOM mineral inventory are based on the 2014 production schedule currently in operation at the Project, historic operating costs through to 2013, and projected metal prices of $1,250 per troy ounce for gold, $23 per troy ounce for silver, $2.75 per pound for copper, and $0.85 per pound for zinc.
The Mineral Resources estimates ("MRE") have been classified as Indicated and Inferred, following the guidelines specified by the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") and adopted for technical reports in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"). Mineral Resources have been estimated as at December 31, 2013, and reported using a gold equivalent (Au + Cu x 1.20 + Ag x 0.02 + Zn x 0.34) cut-off of 2.24 g/t and a breakeven net smelter royalty ("NSR") methodology.

The LOM mineral inventory has been estimated as at December 31, 2013, inclusive of Inferred Mineral Resources and a number of technical-economic factors, to provide an indication of the potential life of the operation. The LOM mineral inventory has been reported using a gold equivalent (Au + Cu x 1.20 + Ag x 0.02 + Zn x 0.34) cut-off of 2.24 g/t and NSR methodology. Therefore, it is important to note that the PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves. There is no certainty that the PEA will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

Scope of the Project
The mine is currently producing run-of-mine material at an average rate of 1,200 tonnes per day. The preliminary economic analysis supporting the LOM mineral inventory estimate, contemplates ramping up production during years 1 and 2, to attain an annual production rate of 1 Mt from year 3. The potential expansion would be achieved through increased development and production rates by increasing the mining equipment fleet currently in use in the operation.
Access into the Kapan mine is via two decline ramps, one to access the south section of the mine, and one to access the north section. Crosscuts are developed from each of the declines. These intersect the veins at approximately 90°. Mine levels are at 15 m vertical intervals. Sub-level open stopes are opened up along the vein drives. Each stope is typically 56 m high and 60 m along strike. Production blast holes are drilled upwards from the lower sub-level, and consist typically of parallel holes. All mine development waste is backfilled into each completed stope.
The veins containing most of the mineralization are narrow, down to 0.2 m in width and up to 2.0 m in width (the average width being about 1 metre). The MRE is modelled to a minimum width of 1.8 metres to include appropriate dilution when required. The minimum stoping width with the sub-level stoping method in use is around 1.8 metres. However, due to geometric, geotechnical and operating factors, stopes can be wider than 1.8 metres, resulting in additional mining dilution. The amount of mining dilution is currently being analysed and procedures reviewed. New drilling machinery is expected to improve efficiency and accuracy of the stope blasting and overall geometry.
Processing Facility
The original infrastructure that processed up to 1 Mtpa of Centralni ore through the 1990s is being utilized for current operations. Following conventional two-stage crushing of run-of-mine material, one of the original grinding circuits (rod mill/ball mill) provides the feed to the first of two sequential flotation circuits. These produce copper and zinc concentrates, both of which contain substantial precious metal credits. Final tailings from the plant are pumped to the tailings management facility, located on the site of the original Centralni tailing facility.
The current milling and flotation circuits are capable of processing at the rate of approximately 750,000 tpa. The additional capacity required for the expansion in throughput may be achieved by refurbishing the currently idle second grinding line, while the capacity of the flotation and downstream circuits may be supplemented, as required, to achieve the 1 Mtpa throughput rate.
The current tailings facility is capable of storing the LOM mineral inventory. However, a substantial upgrade of the infrastructure is required, which has been considered in the project capital estimates. This upgrade is required regardless of the expansion, although the expansion would accelerate the timing.
As part of the ramp up, an options study is underway to compare the introduction of dense media separation to reduce the volume of material being processed, without significantly impacting on metal recoveries and the upgrade of the existing processing facility, for the increased throughput.

The capital cost estimate reflects the initial capital cost and includes sustaining capital and closure and rehabilitation costs.

The NI 43-101 technical report entitled "NI 43-101 Technical Report, Shahumyan Project, Kapan, Republic of Armenia" dated September 30, 2014, in respect of the Mineral Resource and Life of Mine Mineral Inventory estimates disclosed herein (the "Technical Report"), is being filed today on SEDAR at www.sedar.com. Simon Meik, Corporate Director of Processing, and Edgar Urbaez, Corporate Director of Technical Services, both of DPM, who are QPs and not independent of the Company, have also reviewed and approved the contents of this release.
The Mineral Resource and LOM Mineral Inventory estimates contained herein may be subject to legal, political, environmental or other risks that could materially affect the potential development of such estimates. See the Technical Report for more information with respect to the key assumptions, parameters, methods and risks of determination associated with the foregoing Mineral Resource and LOM Mineral Inventory estimates.
Cautionary note to U.S. Investors concerning estimates of Mineral Resources. These estimates have been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of U.S. securities laws. The terms "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are defined in NI 43-101 and recognized by Canadian securities laws but are not defined terms under the U.S. Securities and Exchange Commission ("SEC") Guide 7 ("SEC Guide 7") or recognized under U.S. securities laws. U.S. investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be upgraded to mineral reserves. "Inferred mineral resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an "inferred mineral resource" will ever by upgraded to a higher category. Under Canadian securities laws, estimates of "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies. U.S. investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. Accordingly, these mineral resource estimates and related information may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements under the U.S. federal securities laws and the rules and regulations thereunder, including SEC Guide 7.
