Interested parties are encouraged to read the entire report. The following news release contains excerpts from the report. (2) Average production for Years 2 - 10 (Year 1 includes 6 months of ramp-up; Year 11 production is from the milling of a combination of sulphide ore and some stockpiled oxide ore; Year 12 production is solely from the milling of stockpiled oxide ore). Capital Costs The Yenipazar project is located approximately 220 kilometres southeast of Ankara, the capital of Turkey, 60km south of Yozgat, the provincial centre and approximately 120 kilometres northwest of Kayseri, a city of one million people. The project is well served by existing infrastructure, including paved roads, a railroad, and will be connected to the national power grid. With the benefit of Turkey's excellent infrastructure that is already in place, the majority of the capital expenditures will be spent on developing the project. The pre-production capital costs for the Yenipazar project summarized below are estimated to be $382 million and are based on first quarter 2013 US$ costs. No estimates for escalation or foreign exchange fluctuation have been included in the capital costs. Capital Cost US$ millions Mine Development, Plant & Equipment Mine development $20 Mine equipment $41 Process plant equipment $55 Process plant & infrastructure $119 Tailings facility $37 Power transmission $4 Water management $2 Total $278 Owner's cost (including land acquisition) $31 EPCM $36 Contingency (11%) $37 Total pre-production CAPEX $382 The project requires additional sustaining capital of $58 million, largely to purchase additional mining equipment in Years 1 and 7 ($22 million), for additional tailings management work in Year 3 ($12 million), and for mine closure in Year 12 ($24 million). The sustaining capital requirements are reflected in the financial model. Operating Costs The shallow nature of the ore body and the flat topography of the project footprint and surrounding area allow the Company to benefit from the lower operating costs associated with conventional open-pit mining methods. Operating costs for the tailings management facility have been estimated at approximately $11 million during the 12-year life of the project. G&A includes on-site costs as well as a portion of the costs incurred at the Company's corporate office in Ankara. Total operating costs per ore tonne for the project have been estimated as follows: Operating Cost (LOM) $/tonne of ore Mining $11.15 Processing $16.36 Tailings management $0.31 Water management $0.07 G&A $1.26 Total Operating Cost $29.15 Reserve Estimate The mineral reserves for the Yenipazar project comprise three different mineralization types to be mined and processed: -- oxide mineralization (11% of total); -- copper-enriched mineralization (9% of total); and -- sulphide mineralization (80% of total). The processing characteristics of each are slightly different with the oxide zone yielding three payable metals (Au, Ag, Pb); while the copper-enriched and sulphide zones will yield five payable metals (Au, Ag, Cu, Pb, Zn). The mineral reserve is the portion of the mineral resource that has been identified as mineable within a design pit. The overall pit slope criteria that were used for designing the pit ranged from 26° to 35° in the upper slope (weakened and weathered rock) and from 39° to 49° in the lower slope (competent rock). The strip ratio for the deposit is 4.3:1 including the pre-stripping and drops to 4.0:1 when pre-stripping is excluded. The mineral reserve incorporates ore criteria such as mining recovery, mining losses and dilution. A mining loss factor of 3% and a dilution factor of 14.8% were applied to each ore type. The Probable mineral reserves are summarized in the table below: ____________________________________________________________________________________________________________ | | | Contained Metal | | |_________________________________________________________|__________________________________| | | Tonnage | Au| Ag| Cu| Pb| Zn| NSR| Au| Ag| Cu| Pb| Zn| | | | | | | | | | | | | (M| | | | | (g/t)| (g/t)| (%)| (%)| (%)| ($/t)| (M| (M| (M| lbs)| (M| | | | | | | | | | oz)| oz)| lbs)| | lbs)| |_______________|______________|______|______|______|______|______|_______|______|______|______|______|______| | Oxide | 3,212,000| 0.83| 23.2| 0.24| 0.96| 0.54| 42.23| 0.09| 2.40| | | | | | | | | | | | | | | 16.99| 67.98| 38.24| |_______________|______________|______|______|______|______|______|_______|______|______|______|______|______| | Cu-Enriched| 2,491,000| 0.90| 32.9| 0.45| 0.94| 1.16| 74.72| 0.07| 2.63| | | | | | | | | | | | | | | 24.71| 51.62| 63.70| |_______________|______________|______|______|______|______|______|_______|______|______|______|______|______| | Sulphide | 23,463,000| 0.90| 30.1| 0.29| 0.96| 1.56| 93.32| 0.68| 22.71| | | | | | | | | | | | | | |150.01|496.58|806.94| |_______________|______________|______|______|______|______|______|_______|______|______|______|______|______| | TOTAL | 29,166,000| 0.89| 29.6| 0.30| 0.96| 1.41| 86.10| 0.84| 27.74| | | | | | | | | | | | | | |191.72|616.18|908.88| |_______________|______________|______|______|______|______|______|_______|______|______|______|______|______| -- The mineral reserves are based on NSR cut-off values of USD $17/t for oxide and USD $20/t for copper-enriched and sulphide mineralization. -- The reserve estimate is based on an updated resource estimate (see news release dated November 26, 2012). -- The mineral reserves in this press release were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council. Mining The mining method proposed for the Yenipazar project will be a conventional open-pit mine. An owner-operated fleet of 90-tonne trucks and 10-m(3) hydraulic excavators will be used to mine the ore and waste materials. Drilling and blasting of ore and waste rock will be required, while overburden materials will be free digging. The organic top soil component of the overburden will be segregated and stockpiled separately. These temporary top soil stockpiles will eventually be removed when the material is used as part of the closure plan to cap the tailings dam, waste rock dump, and other disturbed areas. In order to distribute the waste stripping quantities over time and to allow faster access to better grade ore, the pit has been subdivided into four phases that are mined sequentially. Mining may occur in multiple phases simultaneously, depending on the respective strip ratios of ore to waste on the mining benches. Processing As part of the Feasibility Study, an extensive testwork programme was undertaken in order to establish the process design parameters, formulate the process flowsheet, select equipment, evaluate ore variability and confirm metallurgical recoveries. Based on the findings of this testwork programme the process plant design parameters were determined. The design basis of the selected process is based on whole ore processing at a nominal throughput of 2.5 million tonnes per annum. The process plant and design, as detailed in the Feasibility Study, is based on conventional crushing and grinding followed by a gravity circuit where most of the gold and a portion of the silver are recovered. The gravity circuit is followed by sequential flotation of copper, lead, and zinc. 80% of the ore tonnage mined consists of sulphide ore while copper-enriched and oxide ore make up 9% and 11% of the total respectively. Some oxide ore is milled in Year 1 during plant commissioning and ramp-up and the remaining oxide is processed in Years 11 and 12. Sulphide and copper-enriched ore is essentially milled in the year that it is mined. The mill ramp-up rate increases gradually over the first 6 months of operations with full production reached in Month 7. The total tonnage processed in Year 1 is 2.06 million tonnes compared with 2.5 million tonnes in full production. A summary of the milling schedule is included in Appendix B. Recoveries The metallurgical testwork conducted by SGS to-date indicates the following recoveries by ore type. Additional variability testwork was performed on sulphide ore mined and processed in the first four years ofoperations. The results of this testwork are not shown below, but are reflected in the financial model.

After leaching of gold in the gravity circuit, significant optimization of lead and silver recoveries may be achieved by single stage flotation of the leach residue (containing lead and silver) before it joins the lead flotation circuit.Additional gold may be recovered by floatingpyrite in the zinc tailings and subsequently leaching gold from the pyrite.Confirming these potential improvements is a priority following the completion of the Feasibility Study.

The grades of the concentrates are summarized in the table below. Occasional levels of deleterious elements can be expected in the concentrates and a penalty may be incurred due to higher than ideal levels of lead in the copper / gold concentrate. All three concentrates will be marketable. _____________________________________ | |Concentrate| |Product | Grade| |_________________________|___________| |Copper / Gold Concentrate| 26% Copper| |_________________________|___________| |Lead / Silver Concentrate| 56% Lead| |_________________________|___________| |Zinc Concentrate | 53% Zinc| |_________________________|___________| Average annual production for Years 2 - 10 by metal and product is as follows: _______________________________________________________________ | | Gold |Silver| Copper| Lead| Zinc| |Product | (oz)|(M oz)|(M lbs)|(M lbs)|(M lbs)| |_________________________|______|______|_______|_______|_______| |Doré |42,185| 0.1| | | | |_________________________|______|______|_______|_______|_______| |Copper / Gold Concentrate| 6,896| 0.3| 11.2| | | |_________________________|______|______|_______|_______|_______| |Lead / Silver Concentrate|10,404| 1.2| | 33.8| 3.3| |_________________________|______|______|_______|_______|_______| |Zinc Concentrate | 3,157| 0.3| | | 53.0| |_________________________|______|______|_______|_______|_______| |Total |62,642| 1.9| 11.2| 33.8| 56.3| |_________________________|______|______|_______|_______|_______| |% of Revenue | 34.7%| 20.8%| 12.9%| 12.3%| 19.3%| |_________________________|______|______|_______|_______|_______| Infrastructure The proposed mine development involves the construction of an open pit mine, a waste rock dump ("WRD"), a processing plant and a tailings management facility ("TMF") together with the construction of a supporting road infrastructure and various mine-related utilities. Port The port of Iskenderun, which has been identified by the logistics study as the preferred port for the shipping of concentrates, is located approximately 500 kilometres to the south of the project on the Mediterranean Sea. The concentrates will be trucked on existing roads approximately 75 kilometres southwest of the project to a railhead in Himmetdede, where they will then be sent by rail the remaining distance to the port. Power The project will be connected to the national grid with the construction of a 17 kilometre 154 kV power line. Tailings Management To satisfy the lining requirements under Turkish legislation, the TMF will be equipped with a composite lining system constructed from a compacted clay layer sourced from the open pit overburden sediments, a geomembrane layer, and a drainage system. The TMF design incorporates a system to divert water from the valley above the facility, underneath the WRD and around the open pit, from where it will flow down the valley. Tailings from the plant will be pumped to the TMF situated approximately 500 metres south of the plant, where it will be hydraulically deposited. The operating phase of the TMF will commence with commissioning of the plant and first deposition of tailings on the facility. Tailings will be pumped from the plant to the TMF via a slurry delivery pipeline and will initially be deposited from the top of the TMF starter wall into the basin of the lined facility. The maximum height between the crest of the TMF raise and the valley floor will be approximately 38 metres. Water Management The Yenipazar project is located in a gently inclined valley that is drained by a small creek. The open pit, the WRD and the TMF will all be located in the valley and will thus intersect surface water courses as well as the groundwater in the underlying geological formations. Studies conducted to date indicate that run-off from the WRD is relatively inert and therefore it should be possible to dispose of this water to the environment with little or no treatment. A source of fresh make-up water will be required from outside the mine works, particularly during the first year of mining when the TMF is charged-up and water from pit seepage is predicted to become available only towards the end of Year 1 of mining. However, after the first year of mining, clean water from an outside source is only likely to be required to supply potable water to the mine camp and surrounding villages. Testing has demonstrated that nearby aquifers have the potential to supply the required amount of water for these purposes. Royalties The Company, in consultation with its corporate advisors, estimates the effective net profit royalty (revenues less operating expenses) to the Turkish government amounts to approximately 1.6%. In addition to the Turkish government royalty, the Yenipazar project is subject to a 6% net profit interest ("NPI", revenues less operational expenses) to Alacer Gold Corp. ("Alacer") until revenues of US$165 million are generated, and a 10% NPI from there on. Investment Incentives The Turkish government has legislated certain investment incentives designed to promote investment in specific industries and regions of Turkey. The Company has evaluated these investment incentives in consultation with its corporate advisors, and has determined that the Yenipazar project will qualify for the following incentives on successful application and receipt of an investment incentives certificate: -- Reduced corporate tax -- VAT exemption -- Exemption from custom duties -- Support for interest payments -- Social security premium employer share elimination For the purpose of the Feasibility Study, the Company has only incorporated the corporate tax rate reduction and the VAT exemption into the economic analysis. Under the incentive program, the Company would receive income tax savings equal to 40% of the depreciable capital cost required to build the Yenipazar project. Approximately 90% of the total capital costs are depreciable. The income tax savings will be received via a corporate income tax rate reduction from 20% to 4%. For example, for every $100 million of allowable capital cost, the corporate income tax savings would be $40 million, which enhances the after-tax cash flow of the project. Economic Analysis: Base Case Metal Prices The Company has determined to present three economic scenarios using the base case metal pricing assumptions described on Page 1. The first scenario is on a pre-tax project basis and does not reflect the Alacer NPI. The second scenario includes the NPI and the third scenario includes both the NPI and applicable taxes. All scenarios demonstrate robust economics. ______________________________________________________________ | |Pre-NPI, Pre-Tax|After-NPI, Pre-Tax|After-NPI,| | | | | After-Tax| |_______________|________________|__________________|__________| |IRR | 26.4%| 23.8%| 22.5%| |_______________|________________|__________________|__________| |NPV (0%) | $899M| $783M| $707M| |_______________|________________|__________________|__________| |NPV (7%) | $433M| $363M| $323M| |_______________|________________|__________________|__________| |Payback (years)| 2.6| 2.8| 2.9| |_______________|________________|__________________|__________| Economic Analysis: Base Case Metal Prices Minus 10% In the interest of further demonstrating the strength of the Yenipazar project, the scenarios below outline the effect of a 10% reduction to base case metal prices on the economics of the project. _______________________________________________________________ | Base Case Minus 10% Pricing Assumptions | |_______________________________________________________________| |Gold ($/oz)|Silver ($/oz)|Copper ($/lb)|Lead ($/lb)|Zinc ($/lb)| |___________|_____________|_____________|___________|___________| | $1,300 | $25.00 | $2.70 | $0.85 | $0.80 | |___________|_____________|_____________|___________|___________| ______________________________________________________________ | |Pre-NPI, Pre-Tax|After-NPI, Pre-Tax|After-NPI,| | | | | After-Tax| |_______________|________________|__________________|__________| |IRR | 20.3%| 17.9%| 17.0%| |_______________|________________|__________________|__________| |NPV (0%) | $637M| $546M| $513M| |_______________|________________|__________________|__________| |NPV (7%) | $275M| $220M| $199M| |_______________|________________|__________________|__________| |Payback (years)| 3.1| 3.7| 3.9| |_______________|________________|__________________|__________| Sensitivity Analysis (Base Case) The graph below shows the sensitivity of NPV(7) (Pre-Tax, Pre-NPI) to capital costs, operating costs, and revenue using base case metal prices. The value of the project is more sensitive to revenue than to capital and operating costs. Additional sensitivity analyses are included in Appendix A. http://files.newswire.ca/899/AldridgePDF.pdf Permitting In accordance with Turkish law, an Environmental Impact Assessment ("EIA") report on the Yenipazar project must be submitted for approval by the Turkish government. The EIA approval process involves the filing of an initial application defining the scope of the proposed project (completed), a public consultation process (completed), and a final submission. In parallel with the EIA, Aldridge is also preparing an Environmental and Social Impact Assessment report in accordance with international standards. The Company expects to submit its Turkish EIA by early Q3 2013 and will also proceed to apply for operating, construction and other required permits following receipt of the EIA permit. Development Timeline Once initiated, it is estimated that construction will take approximately 21 months and will be followed by a 2-month period of plant commissioning and production ramp-up estimated to take 6 months. Full commercial production will follow thereafter.
