Retransmission: Chesapeake Announces Positive Preliminary Economic Assessment for Metates

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 22, 2010) - Chesapeake Gold Corp. ("Chesapeake") (TSX VENTURE:CKG) is pleased to announce the results of a positive Preliminary Economic Assessment ("PEA") on its large 100% owned Metates gold-silver project located in Durango State, Mexico. The NI 43-101 compliant PEA was prepared by M3 Engineering & Technology of Tucson, Arizona ("M3") with input from other prominent industry consultants.

The PEA indicates a large tonnage open pit mining operation using conventional mining and milling methods to produce a sulphide concentrate followed by pressure oxidation to be feasible using current and projected future economic conditions. Highlights of the PEA using base case prices of $900 per ounce gold, $14 per ounce silver and $1.00 per pound zinc are as follows. All costs are quoted in US dollars and reference to "gold equivalent" refers to gold plus the gold equivalent of silver only, at gold to silver ratio of 1:64.3.

- Base case ultimate pit mining 852 million tonnes of ore containing 17.4 million ounces gold, 463 million ounces silver and 3 billion lbs of zinc with a life of mine (LOM) strip ratio of 1.75 to 1

- 27 year LOM production at 90,000 tonnes per day of ore throughput

- Annual average gold equivalent production during the first seven years of full operation averages 963,200 ounces at a direct cash cost of $326 per ounce excluding zinc credits, $267 per ounce including zinc credits

- LOM average annual gold equivalent production of 772,700 ounces at a direct cash cost of $419 per ounce excluding zinc credits, $366 per ounce including zinc credits

- Estimated initial capital cost of $3.19 billion including $493 million in contingency costs and working capital

- Unleveraged pre-tax internal rate of return ("IRR") of 13.0% and a net present value ("NPV") of $1.2 billion at an 8% discount rate, including zinc recovery

- Payback period of 5.7 years and an undiscounted cumulative LOM net cash flow of $11.0 billion, on a pre-tax basis and including zinc recovery.

The PEA is based upon a new NI 43-101 compliant in-pit mineral resource estimate by Independent Mining Consultants of Tucson, Arizona ("IMC") at a gold price of $900 per ounce and a cut-off grade of 0.40 g/t gold equivalent.

Contained Metal   2,611,000 oz 62,219,000 oz 3,572,000 oz 357,881 (Klbs)

* Gold Equivalent equals Gold plus Silver/64.3, assuming equal metal recoveries

This new resource increases the existing (see news release dated May 7, 2009) Measured + Indicated mineral resources by 2.4 million ounces gold, 70 million ounces silver and 790 million pounds zinc and the Inferred mineral resources by
0.7 million ounces gold, 24 million ounces silver and 145 million pounds zinc.

IMC prepared the mine schedule used in the PEA from the new resource which includes Inferred mineral resources which are considered to be too speculative geologically to have economic considerations applied that would enable them to be categorized as mineral reserves. There is no certainty that all or any part of the mineral resources will be converted into mineral reserves. The PEA is an estimate of the economic viability of the project and there is no certainty that the results projected will be realized and actual results may vary substantially. A variable gold equivalent cut-off grade ranging from 0.55 g/t to 0.43 g/t was used to optimize the grades and waste:ore ratio in the early years of production. The resource used in the PEA mines a lower tonnage but higher value portion of the updated resource estimate using 0.40 g/t gold equivalent cut-off grade.

* Mineral resources that are not mineral reserves do not have demonstrated economic viability.

The initial capital costs, including contingency and working capital and the zinc recovery plant are estimated at $3.19 billion or approximately $153 per ounce of LOM gold equivalent production. Average operating cost per tonne of ore mined LOM including mining, processing and G&A is estimated at $11.58, including zinc recovery. The capital and operating costs are current to second quarter 2010.

 Capital and Operating Costs Summary

Initial $ 2.701 billion Mining Cost $ 0.90 per tonne
Contingency and working capital $ 0.493 billion Processing Cost $ 10.28 per tonne
Sustaining (including reclamation and salvage) $ 0.705 billion G&A Cost $ 0.40 per tonne
Total $ 3.899 billion Total $ 11.58 per tonne

The PEA is based on a mine production rate of 90,000 tonnes per day processed by a crushing and grinding system utilizing high pressure grinding to feed a sulphide flotation plant. The bulk sulphide rougher flotation concentrate representing about 11% of the original weight of the ore, will be transported by slurry pipeline 140 kilometres downhill to an area of relatively flat terrain proximate to a large limestone resource as well as existing power, water and supporting infrastructure. The concentrate will be treated via pressure oxidation with subsequent cyanidation and Merrill-Crowe recovery of gold-silver dore. Acidic solutions from pressure oxidation will be treated with limestone and lime produced on-site. A new process will be used to produce high quality zinc metal sulphide from the pressure oxidation solutions, with the sulphides shipped to a smelter for final processing. Electrical power is to be supplied from a dedicated coal fired power plant which is included in the initial capital cost. Overall gold and silver recoveries from ore through dore production are estimated at 84.7%. Overall zinc recovery is estimated at 85%. The PEA forecasts a 27 year mine life. Total LOM production is expected to recover 14.8 million ounces gold, 391 million ounces silver and 2.44 billion pounds of zinc.

The base case economic evaluation on a pre-tax basis and with ± 10% sensitivities are provided in the table below, which includes zinc recovery:

After two years of comprehensive work, management is very pleased with the results of the PEA. As a result, the Company plans to rapidly advance Metates towards pre-feasibility which is estimated to cost about $3.0 million and take approximately 12-15 months to complete. Chesapeake believes the project economics can be improved by further work and trade-off studies investigating alternative zinc recovery methods, access road alignments and independent power sources. Excellent potential exists to expand the current gold resource at Metates as the deposit remains open along trend in both strike directions. As such, a significant tonnage of material within the existing pit design that has not been drill-tested is presently classed as waste rock.

Chesapeake currently has 38,309,797 shares outstanding and approximately C$12.0 million in cash and liquid investments.

Mr. Gary Parkison, Metates Project Manager and a Qualified Person as defined by NI 43-101 supervised the preparation of the technical information in this release. Mr. Doug Austin P E , Senior Vice President with M3 and Mr. Michael Hester
F AUS IMM, Vice President of IMC have also reviewed and approved the data in this new release.

The NI 43-101 PEA Technical Report will be available late May at and on the Company's website. For more information on Chesapeake and its Metates Project, please visit our website at or contact investor relations at 604-731-1094.
