Perseus Mining Limited Updates Edikan Mineral Resource

PERTH, WESTERN AUSTRALIA -- (Marketwired - Aug. 26, 2014) - Perseus Mining Limited ("Perseus" or the "Company") (TSX:PRU) (ASX:PRU) reports that following an infill drilling programme on the Edikan Gold Mine ("EGM") mining leases in Ghana in the period up to June 2014, and after adjusting key assumptions to reflect actual results to date, Mineral Resource estimates have been updated by independent consultant, RungePincockMinarco in accordance with the JORC Code - 2012 Edition. A detailed summary of the current Mineral Resource estimate for each of the mineral deposits identified to date on the EGM tenements, calculated using a 0.40 g/t gold cut-off grade, is presented in the Attachment. A Table 1 as required by the JORC Code (2012) for each of the revised Mineral Resource estimates are included in the full report which is available for download from www.perseusmining.com and www.asx.com.au.

The Mineral Resource estimates take into account mining depletion as at 30 April 2014 as relevant.

In summary, the revised global Mineral Resource estimate for the EGM is as follows:

Table 2: EGM Inferred Mineral Resources

Gold (oz)
Oxides	2,960	1.1	109,100

Fresh	68,680	1.0	2,137,000
TOTAL	74,770	1.0	2,355,700

Relative to the previous Mineral Resource estimate for EGM published in June 2013, the updated Mineral Resource contains 357,300 fewer ounces of gold in the Measured and Indicated categories and 74,300 fewer ounces in the Inferred category. After adjusting both Mineral Resource estimates to the mining surface as at 30 April 2014, the net decrease in Mineral Resources is 155,500 ounces (2.8%) in the Measured and Indicated category and 73,800 ounces (3.0%) in the Inferred category.

Work is underway on revising the design of each of the pits based on the updated Mineral Resources as well as key operating parameters, and reassessing the sequence in which each of the pits will be brought into production, with the objective of maximising cash flow generated by the Edikan operation. The revised Life of Mine Plan and updated Ore Reserve statement is expected to be completed in the December 2014 Quarter.


Comment from Managing Director, Jeff Quartermaine

"The overall change to Edikan's Mineral Resource estimate is relatively immaterial but it does reflect several points worth noting.

"The first is that actual conditions encountered once mining operations commence do not always totally mirror assumptions made when initial mine planning takes place. In this case the bulk density of ore mined in the AF Gap and Fobinso pits is slightly different to what was assumed in prior Mineral Resource estimates and when this difference is factored into Mineral Resource calculations, it does have an impact, albeit, reasonably small.

"The second key takeaway from the current Mineral Resource estimate is that our recent infill drilling programme at Bokitsi South has been successful in identifying mineable material with a head grade well above the life of mine average ore grade that may lead to an increase in the average head grade of ore processed by our mill.

"The grade of the Mineral Resources in the Bokitsi North and South deposits has increased from 2.6g/t to 3.0g/t and the amount of contained metal has also increased slightly. Further infill drilling is planned at Bokitsi South that will particularly target extensions to the ore body to the south and at depth where the mineralisation appears to remain open. An infill drilling programme is also currently underway at Mampong with the aim of delineating higher grade material and this will be extended to other deposits at Edikan in due course, subject to budgetary constraints."
