FORWARD–LOOKING STATEMENTS
2
This presentation contains “forward-looking information” or "forward-looking statements" that involve a number of risks and
- uncertainties. Forward-looking information and forward-looking statements include, but are not limited to, statements with respect to the
future prices of gold and other metals, the estimation of mineral reserves and resources, the realization of mineral estimates, the timing and amount of estimated future production, costs of production, capital expenditures, costs and timing of the development of new deposits, success of exploration activities, permitting time lines, currency fluctuations, requirements for additional capital, government regulation of mining operations, environmental risks, unanticipated reclamation expenses, title disputes or claims, limitations on insurance coverage and timing and possible outcome of pending litigation. Often, but not always, forward-looking statements can be identified by the use of words such as “plans”, “expects”, or “does not expect”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates”, or “does not anticipate”, or “believes”, or variations of such words and phrases or state that certain actions, events or results “may”, “could”, “would”, “might” or “will” be taken, occur or be achieved. Forward-looking statements are based
- n the opinions and estimates of management as of the date such statements are made, and they involve known and unknown risks,
uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any other future results, performance or achievements expressed or implied by the forward-looking statements. Such factors include, among others: the actual results of current exploration activities; actual results of current reclamation activities; conclusions of economic evaluations; changes in project parameters as plans continue to be refined; future prices of gold; possible variations in ore grade or recovery rates; failure of plant, equipment or processes to operate as anticipated; accidents, labour disputes and other risks of the mining industry; delays in obtaining governmental approvals or financing or in the completion of development or construction activities, fluctuations in metal prices, as well as those risk factors discussed or referred to in this news release under and in the Company’s annual information form under the heading "Risk Factors" and other documents filed from time to time with the securities regulatory authorities in all provinces and territories of Canada and available at www.sedar.com. Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be anticipated, estimated or intended. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers are cautioned not to place undue reliance on forward-looking statements.

- The Chelopech mineral deposit lies in the northern part of the
Panagyurishte mining district where a number of copper-bearing massive sulphide and porphyry copper deposits exist.
- The Company acquired its mining rights (i.e. Mining License) under
a Concession Agreement with the Bulgarian Government , signed in 1999 for a period of 30 years.
- The Mining License covers an area of 266 hectares and includes the
area of the Chelopech mining operation and its immediate
- surroundings. The Company owns the land upon which the facilities
are constructed.
- The mine has operated since the early 1950’s.
- The operation was acquired by Dundee Precious Metals in 2003.
Chelopech Gold/Copper Mine
13
Chelopech Gold/Copper Mine
- The mine currently produces approximately 75,000 ounces of gold
and 12,000 tonnes of copper per annum in a high arsenic concentrate grading approximately 16.5% copper and approximately 30 g/t gold.
- The target growth plans are to grow production since acquisition
from 550,000 tonnes per year to 2,000,000 tonnes per year.
- All concentrates produced are currently processed through the
Tsumeb Smelter. In March 2010 DPM purchased the Tsumeb Smelter in Namibia.

- Chelopech Mining is situated in traditional old mining
region;
- Since 90s of the last century neither state nor industry care
for the environment;
- Damaged areas from past mining activities can be seen all
around the region;
- Three mining companies (two open pits, one underground
mine) and one smelter operate in the region;
- In the region: five TMFs constructed; one of them already
rehabilitated.

115
Chelopech – Path Forward
Why the Need for Change
- Expansion to 2MT will require a 30 % productivity
improvement and 44% unit cost improvement
- Current performance contains waste in the form of
– poor use of resources – low performing employees – inefficient use of the shift time – poor planning – conflicting activities – bottlenecks
- Improvements will only come with a change in the way we
manage the operation to reduce or eliminate the waste and motivate the people.
116
- System and process view for the operations to allow
better integration and optimization
- Computerized Maintenance Management System,
integrated with the other systems on site
- Enhanced training system to ensure the right
competencies and skills for the operators / fitters
- Use models to identify bottlenecks on a timely manner
(Production, Simulation, Stope Cycle)
- Initiate Projects to improve efficiency in
– Work execution – Mobile maintenance facilities – Haulage – Production drilling and blasting
