Dundee Precious Metals Inc. (TSX:DPM)(TSX:DPM.WT.A) ("DPM" or "the Company") is pleased to report the positive technical results outlined in its preliminary economic assessment ("PEA") of the pyrite recovery project (the "Pyrite Project") at its Chelopech Mine in Bulgaria. "We are excited by the potential of this Pyrite Project and the opportunities it may create for us in the future. Should this proceed, the study indicates that up to an additional 85,000 oz of gold could be recovered annually from Chelopech, increasing the gold contained in concentrate recovery from 55% to 90%", stated Jonathan Goodman, President and CEO.

Background

Chelopech is an underground gold, copper and silver mine, which currently produces a copper concentrate with metal recoveries averaging 55%, 85% and 42%, respectively. The work has confirmed that with this Pyrite Project there is potential to recover most of the unrecovered gold, silver and copper. The bulk of these unrecovered metals are mainly associated with the mineral pyrite, which is currently rejected in the flotation process to ensure a saleable copper concentrate. The PEA is based on the Mineral Reserves reported in the National Instrument 43-101 ("NI 43-101") Technical Report for the Chelopech Project, Bulgaria filed on SEDAR on March 25, 2011. At the full mine production rate of 2 million tonnes per annum, approximately 400,000 tonnes of pyrite concentrate could be generated from the mill feed as a separate concentrate product in addition to the copper concentrate already produced. Initial flotation test work has indicated that a pyrite concentrate would contain:

Contained Metal Content Annual Production
Pyrite concentrate 380,000 - 420,000 tonnes
Gold (@ 6-7 g/t) 75,000 - 90,000 oz
Silver (@ 10-15 g/t) 130,000 - 190,000 oz
Copper (@ 0.5%-0.7%/t) 4.5 - 6.0 M lbs

Project Description

An initial desktop study assessed several options for further processing of this concentrate to recover the gold and other economic metals contained following which bench scale test work was conducted on the highest potential options. The test work included roasting, atmospheric oxidation, pressure oxidation ("POX") and biological oxidation, each with the subsequent leaching and smelting. This work has indicated that a POX process or autoclave could be used to produce a low mass metals rich residue containing high values of gold and silver.

Subsequent laboratory and pilot scale test work conducted at the SGS Lakefield laboratory in Canada has confirmed the technical viability of this process. Results to date have shown that a product containing 30-60 g/t of gold and 25-75 g/t of silver, with recoveries of 95% of the gold and approximately 50% of the silver, can be produced. There is a significant mass reduction which provides a unique opportunity to produce a product which can be transported economically to DPM's smelter in Namibia.

It is proposed that the copper and silver remaining in the acid solution after the POX process would be recovered through a precipitation process as part of the neutralization stages.

This solution will be neutralized in several stages using limestone, which will form gypsum. This will then be disposed of in a properly designed waste storage facility adjacent to the existing tailings storage facility.

The test work shows the following products will be produced from this process:

Oxidation Products Annual Production
Solid residue 40,000 - 80,000 tonnes
Gold (@ 30 - 60 g/t) 70,000 - 85,000 oz
Silver (@ 25 - 75 g/t) 60,000 - 100,000 oz
From the solution
Copper (as precipitate) 3.0 - 4.5 M lbs
Silver (as precipitate) 35,000 - 80,000 oz
Neutralized waste 1.2 - 1.5 M tonnes

Further flow sheet test work and conceptual studies will be conducted in the next three months to complete the basis for input to the feasibility study, which is expected to commence in the fourth quarter of 2012.

Project PEA

The Pyrite Project is expected to be implemented in two stages. The first stage is a pyrite concentrate circuit, which includes a new flotation, thickening and filtration installation in the existing mill facility. This requires minimal capital and permitting and can immediately generate a pyrite concentrate for sale to smelters to generate some initial cash flow while the remaining phases of the Pyrite Project are being designed, permitted and constructed. A stockpile of pyrite concentrate, previously produced at Chelopech, is currently being sold to smelters confirming that there is a market for this product. The PEA assumes the sale of a portion of the 400,000 tonnes of pyrite concentrate available for the period 2013 - 2016. The remaining portion would be stockpiled for later processing through the POX facility.

The second stage would be the construction of the POX facility, which is expected to be done in two phases to reduce the Pyrite Project risk and to make use of the existing autoclave, oxygen plant and other equipment already owned by DPM and not used in a previous project. Phase 1 would allow for the processing of approximately 200,000 tonnes, or half, of the annual pyrite concentrate. Completion of a feasibility study and environmental permitting is expected to take up to two years from initial start in early 2013. Assuming the foregoing milestones are achieved within this time frame, the Pyrite Project construction would be expected to be completed within one year with operation of the first phase beginning in 2016.

The second phase of the POX facility (comprising an additional autoclave and associated infrastructure) would be capable of processing the remaining 200,000 tonnes of pyrite concentrate. Construction would commence after it has been confirmed that the first phase has been operating successfully. The PEA assumes construction would take place in 2016 with start-up commencing in 2017.

Preliminary capital cost estimates for each phase of the Pyrite Project are as follows:
