PERTH, WESTERN AUSTRALIA--(Marketwired - March 5, 2015) -

NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

Perseus Mining Limited ("Perseus" or the "Company") (TSX:PRU) (News - Market indicators) is pleased to advise that it has purchased four new Caterpillar diesel driven generators capable of producing in total up to 5.8MW of power to boost its on-site power generating capacity at its Edikan Gold Mine ("Edikan") in Ghana.

The equipment which was purchased from Mantrac Ghana Limited and associated infrastructure will cost approximately US$3.3M (including taxes) and once installed on site the four generators will be able to generate sufficient power to fully compensate for the power that Perseus is unable to draw from the national grid under measures introduced by the Ghanaian government in response to a country-wide power shortage.

Taking into account estimated delivery and installation time, this acquisition should ensure that the Edikan processing plant can operate unimpeded by power disruptions from approximately mid April 2015 onwards. The net incremental cost of generating power using the diesel fired generators is not estimated to be material in the context of Edikan's all-in sustaining cost of gold production.

Perseus has also commenced studying a range of alternative longer term energy solutions designed to provide Edikan with a secure supply of power that is not reliant on the national electricity grid. In the event that the recently purchased generators are no longer needed on the Edikan site, they may be re-deployed as the primary energy source for Perseus's Sissingué Gold Mine in neighbouring Côte d'Ivoire.

Background

In early December 2014, the Ghanaian government announced a plan to reduce the amount of power available to Perseus (and other mining companies operating in Ghana) by up to 25% in response to the country's power shortages. This arrangement remained in place until late January 2015, during which time the impact of reduced power availability on Perseus's gold production in December 2014 and January 2015 was minimal as a result of the use of an existing standby generator and managing the composition of ore fed to the SAG mill.

In late January 2015, the government increased the amount of compulsory load shedding required of mining companies to 33% of normal base load power draw and introduced a roster which temporarily permitted Edikan to draw power for only four days out of every six. Under this scenario, production during the month of February 2015 was approximately 6,500ozs below target notwithstanding outstanding operational performances in terms of throughput rates, head grade and gold recovery when power was available to enable the processing plant to operate.

Edikan's additional power generating capacity will take effect from around the middle of April 2015, which means that gold production from Edikan for the next seven weeks will be reduced by approximately one third of what was originally planned for this period. Beyond that point, it is expected that the operation will perform at or above previously forecast levels.

Revised Production Guidance

As a result of the above, it now appears likely that in the absence of an unexpected improvement in the availability of power in Ghana prior to mid April 2015, Perseus will be unable to produce sufficient gold to meet the production guidance that it has previously provided to the market for the six months and twelve months ending June 30, 2015.

Previous production and cost guidance provided to the market was as follows:

Based on current forecasts, the following production profile appears more likely:

It should be noted that in the two months to February 28, 2015, Perseus produced 32,339 ozs of gold which means that in order to produce to the mid-point of the revised June 2015 Half Year guidance range, the mine will need to produce on average approximately 18,200ozs of gold per month, which is considered achievable given the excellent recent operational performance at the mine, notwithstanding power shortages.

All production targets for Edikan referred to in this news release are based on estimated Ore Reserves that have been prepared by competent persons in accordance with the requirements of the JORC Code, 2012 Edition.
