Forward-Looking Statements
This presentation contains or incorporates by reference “forward-looking information” under applicable Canadian securities legislation. Except for statements of historical fact relating to the
Company, information contained herein constitutes forward-looking statements, including any information as to the Company’s strategy, plans or future financial or operating performance.
Forward-looking statements are characterized by words such as “plan,” “expect”, “budget”, “target”, “project”, “intend”, “believe”, “anticipate”, “estimate” and other similar words, or statements
that certain events or conditions “may” or “will” occur. Forward-looking statements are based on the opinions, assumptions and estimates of management considered reasonable at the date
the statements are made, and are inherently subject to a variety of risks and uncertainties and other known and unknown factors that could cause actual events or results to differ materially
from those projected in the forward-looking statements. These factors include, but are not limited to, the impact of general business and economic conditions, global liquidity and credit
availability on the timing of cash flows and the values of assets and liabilities based on projected future conditions, fluctuating metal prices (such as gold, copper, silver, nickel and iron ore),
currency exchange rates (such as the Canadian dollar, Brazilian Real, Mexican Peso and the Honduran Lempira versus the United States dollar), possible variations in ore grade or recovery
rates, changes in accounting policies, changes in the Company’s corporate resources, changes in project parameters as plans continue to be refined, changes in project development and
production time frames, the possibility of project cost overruns or unanticipated costs and expenses, higher prices for fuel, steel, power, labour and other consumables contributing to higher
costs and general risks of the mining industry, failure of plant, equipment or processes to operate as anticipated, unexpected changes in mine life, final pricing for concentrate sales,
unanticipated results of future studies, seasonality and unanticipated weather changes, costs and timing of the development of new deposits, success of exploration activities, successful
completion of proposed acquisitions, permitting time lines, 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 and labour disputes, as well as those risk factors discussed or referred to in the Company’s Annual
Information Form under the heading “Item 4.2 – Risk Factors”. 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. The Company
undertakes no obligation to update forward-looking statements if circumstances or management’s estimates, assumptions or opinions should change, except as required by applicable law.
The reader is cautioned not to place undue reliance on forward-looking statements. The forward-looking information contained herein is presented for the purpose of assisting investors in
understanding the Company’s expected financial and operational performance and results as at and for the periods ended on the dates presented in the Company’s plans and objectives and
may not be appropriate for other purposes.

Forward-Looking Statements and Cautionary Notes
TSX : ORA 2
Introduction
TSX : ORA 3
Mine Plan Options:
1. Continue to mine with existing fleet and try to “catch-up” waste strip
2. Split pit North and South (2 phase)
3. Split pit East and West (2 phase)
4. Dedicated waste stripping for 3-4 months – complete waste push
back and change overall mine operations and development plan
TSX : ORA 4
Option 1
1. Continuing as is - not working
2. Waste catch-up is too slow – contractor fleet inadequate to
achieve mine plan and catch up on stripping; pit layout
completely inefficient to allow accelerated strip – Congested
operation
3. Operating costs for this option could impair asset
4. Waste dilution high and pit operations totally inefficient - refer to
photo on Slide 7
TSX : ORA 5
1. Split Pit either N/S or E/W
2. Has certain benefits in terms of phasing out waste strip and using
mined out areas for waste storage
3. Study showed that these options would still provide low grade ore for
several months and would still have ore dilution – though less than
current practice.
4. Layout of pit would also cause difficulties in implementing phased pit
Option 2 – Split Pit

Sao Francisco – 3-4 Month Waste Stripping Plan
TSX : ORA 12
Dedicated 3-4 months stripping plan
• Concentrate on mining waste
• Remove 4-5 Mt.
• Expose all ore in H/W and Footwall
• End up with 30 m wide operating benches,
• Ore grade after start-up will be 0.8 -1.0 g/t CGO and 0.37 g/t DLO.

Sao Francisco – Benefits
TSX : ORA 13
Benefits include:
• Wider benches for better blasting and mining efficiency –
eliminate dilution
• Greater potential to mine in lifts – more efficient operations
• Building “wide bench” operating philosophy into operating
plan – double side loading and more efficient mining.
Convert backhoes to “front shovel” configuration
• Sustainable ore release
• Improved haulage roads, less congestion
• Maintenance time for plant / crusher / gravity circuit

Sao Francisco – Tailing Re-Treatment Economics
TSX : ORA 15
• Estimated Capex $12-14 million (depending on used
equipment availability)
• Estimated production – 9,000-11,000 oz/annum
• Cash costs $200-250/oz
• Payback <12 months
Sao Francisco – Cash Cost Reductions on Restart
TSX : ORA 16
• Independent studies indicate savings in operation of crushing/gravity
circuit of approximately $1.00/t treated. However, Company project
savings conservatively based on $0.50/t for $2.4 million/annum
• Savings of $0.45/t on replacement of crushed rock haulage contractor
with owners fleet or $1.9 million/annum – Majority of fleet available at
site
• Negotiation of new contracts for fuel and cyanide now complete for
savings of $4.8 million/annum
• Currency hedging – annualized savings of $2.4 million until mid-2012
• Above does not include potential cost reductions in mine contract due
to revised pit plan – negotiations to commence end November
• Total savings $8-10 million/annum
Sao Francisco – Cash Costs
TSX : ORA 17
• Production Forecast
– Heap and gravity – 90,000 -95,000oz/annum
– Tailings retreatment – 10,000-11,000 oz/annum
– Total production – 100,000 -106,000oz/annum
• Projected Annual Operating Costs - $74 million
• Projected Cash costs 700/oz – 740/oz
