TORONTO, ONTARIO--(Marketwired - Mar 31, 2014) -
(All amounts have been expressed in US Dollars except where otherwise indicated)
Dundee Precious Metals Inc. (TSX:DPM) (TSX:DPM.WT.A) ("DPM" or "the Company") announces the results of the updated Mineral Reserve and Mineral Resource for its Chelopech mine in Bulgaria.
Highlights:
- Life of mine ("LOM") extended from 2023 to 2025
- Measured tonnes increased 13%, or 2.2 million tonnes ("Mt"), from September 2011 estimate
- Pyrite recoveries incorporated into Mineral Reserve estimation
- LOM assumptions maintain gold price of $1,250 per ounce
- Pyrite recovery circuit commissioned in Q1 with an annual gold capacity in pyrite production of up to 80,000 oz of gold; concentrate contracts in 2014 for 240,000 tonnes and 40,000 oz contained gold
- First shipment of pyrite concentrate to Xiangguang Copper Co. completed in March
- 18 months of stable operation at the 2 million tonnes per year rate, combined with the newly introduced pyrite recovery circuit, allows incremental tonnage, recovery and profitability optimization steps in keeping with DPM's continuous improvement core value
"The addition of a further two years to the LOM of our flagship asset is an encouraging outcome from our reserve and resource update, which now incorporates pyrite recovery as a result of our newly constructed capability to treat all pyrite feeds rather than discard pyrites to tailings," stated Rick Howes, President and CEO. "We have recently completed our first shipment of pyrite concentrate and expect to be able to meet our 2014 contractual obligations."
The 2005 metallurgical testwork characterized the hardness and flotation parameters of each mineralized block, and confirmed that the process flowsheet currently in operation was optimum for the production of copper/gold concentrates. An additional test program was completed in 2012, covering current and future ores, which confirmed the current flowsheet performance for the copper circuit, and developed the optimum conditions for the future recovery of pyrite from the current process plant ore feed.
The expanded ore treatment process was completed in early 2012. Further plant upgrades have been completed since the original expansion, including the replacement circuit for the second and third cleaners of the copper circuit in mid-2013, and a new pyrite circuit that commenced operation in the first quarter of 2014.
Mineral Reserves have been estimated as at December 31, 2013, and are based on, and inclusive of, Mineral Resources, and include approximately 71,000 tonnes of broken stocks and stockpiles. Mineral Reserves are reported using a gold equivalent (Au + Cu*2.06) cut-off of 3 g/t and a Net Smelter Return ("NSR") methodology.

Mineral Reserves have been estimated by including a number of technical, economic and other factors. A change to any of the inputs would therefore have some effect on the overall results. Concerning mining and metallurgical factors, it is the belief of CSA Global (UK) Ltd. ("CSA") that sufficient work has been done by DPM to ensure that these are not likely to have any significant or material effect on Mineral Reserves. The quality of the ore reserves means that a high level of mine planning can be instituted and complied with.
Mineral Resources have been classified as Measured, Indicated and Inferred, following the guidelines specified by the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") and adopted for technical reports complying with National Instrument 43-101 ("NI 43-101"). Mineral Resources have been estimated as at December 31, 2013, and reported using a gold equivalent (Au + Cu*2.06) cut-off of 3 g/t and a breakeven NSR methodology.
MINERAL RESOURCES | GOLD | SILVER | COPPER | ||||||||||
Tons M | Grade g/t | Oz M | Grade g/t | Oz M | Grade % | Pounds M | |||||||
Measured | 18.6 | 4.07 | 2.431 | 9.72 | 5.808 | 1.35 | 553 | ||||||
Indicated | 10.2 | 3.96 | 1.293 | 8.39 | 2.742 | 1.06 | 237 | ||||||
Measured and Indicated | 28.7 | 4.03 | 3.724 | 9.25 | 8.550 | 1.25 | 791 | ||||||
Inferred | 8.2 | 2.71 | 0.712 | 11.22 | 2.952 | 0.92 | 166 |
Compared to the September 2011 Mineral Resources estimate, for combined Measured and Indicated material, the updated estimate for Measured tonnes has increased by 13% (or 2.2Mt). Inferred material has 15% fewer tonnes with a 12% increase in copper, 7% increase in gold and 11% increase in silver. The primary reason for these changes are tonnage losses due to production of 2.5 Mt of ore treated during the period October 1, 2012 to December 31, 2013, offset by increases in resources from development drilling success.
It is CSA's opinion that the Mineral Resources estimate has a very low to negligible risk of being affected by factors such as geological understanding, data mismanagement, poor estimation methodology or poor classification strategy. The deposit geology is well understood, has been appropriately modeled in 3D and has adequate sampling data to support the grade and tonnage estimates. Recent reconciliation with production has verified the quality of the Mineral Resources estimate.
Mineral Resources and Reserves are based on the 2014 ore production schedule, operating costs through to 2013, with current projected metal prices of $1,250 per troy ounce price for gold, $2.75 per pound for copper, and $23 per troy ounce for silver.

The NI 43-101 technical report entitled "NI 43-101 Technical Report, Mineral Resource and Mineral Reserve Update, Chelopech Project, Chelopech, Bulgaria" dated March 21, 2014, in respect of the Mineral Resource and Mineral Reserves estimates disclosed herein (the "Technical Report"), is being filed today on SEDAR at www.sedar.com. Simon Meik, Vice President, Processing, and Edgar Urbaez, Corporate Director, 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 Mineral Reserve estimates contained herein may be subject to legal, political, environmental or other risks that could materially affect the potential development of such Mineral Resources. 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 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.
