Perseus Mining's Edikan plan shows 230,000 oz Au a year 2013-10-15 07:35 ET - News Release Mr. Jeffrey Quartermaine reports REVISED MINE PLAN FOR PERSEUS MINING'S EDIKAN GOLD MINE Perseus Mining Ltd. has released details of its revised life of mine plan for the Edikan gold mine in Ghana, West Africa. HIGHLIGHTS -- The revised LOMP is based on seven open pits designed using US$1,200/oz pit shells, containing 6% less gold than the previous LOMP but requiring mining of 15% less ore and waste, resulting in material cash flow benefits. -- Production and cost guidance for FY 2014 of +/- 200,000 ounces at an all-in site cash cost(1) of +/- US$1,100/ounce remains unchanged. -- For the period from FY2015 to FY2018, average gold production increases with an increase in grade relative to FY2014 to 240,000 ounces/year at an average all-in site cash cost of US$1,050/ounce. -- The LOMP estimates average gold production of 230,000 ounces/year at an all-in site cash cost of US$937/ounce from FY2014 to FY2024. -- The independent estimate of the Ore Reserves for the EGM as at 1 July 2013 indicates Proved and Probable Ore Reserves totalling 82.7 million tonnes of ore grading 1.1 g/t of gold and containing 2.925 million ounces of gold. Comments from Perseus's Managing Director, Jeff Quartermaine "The revised Life of Mine Plan for the Edikan Gold Mine represents a robust and financially attractive way forward for our flagship operation. The plan clearly indicates that at a gold price of US$1,200/ounce, a significant amount of cashflow can be generated at Edikan, and at even lower gold prices the operation remains viable, based on our assumptions. Going forward, our financial performance will continue to be highly leveraged to the gold price and operational improvements, and the revised LOMP represents an important element in our ongoing efforts to improve our operating performance on the EGM site." (1)All in site cash costs include direct production costs, royalties, investment in waste stripping and sustaining capital expenditure. It does not include exploration expenditure, income taxes or corporate costs. MINERAL RESOURCES Following an infill drilling programme on the EGM mining leases in the period up to early June 2013, an updated Mineral Resource estimate was prepared for the Company by mining consultants, RungePinco**Minarco ("RPM") in accordance with the JORC Code - 2004 Edition. A detailed summary of the current Mineral Resource estimate for each of the mineral deposits identified to date on the EGM mining leases, calculated using a 0.40 g/t gold cut-off grade, was published in Perseus's June 2013 Quarterly Report. In summary, the revised global Measured and Indicated Mineral Resource estimate for the EGM, which takes into account mining depletion as at 30 April 2013, was estimated as 162.5 million tonnes grading 1.1g/t gold and containing 5.7 million ounces of gold. A further 77.4 million tonnes of material grading 1.0g/t gold and containing a further 2.4 million ounces of gold were classified as an Inferred Mineral Resource. Details of these estimates are shown below in Tables 1 and 2 respectively.

This exercise involved varying key parameters such as the pit development sequence, applying technical assumptions that reflected actual operating parameters, and working within known constraints such as the expected timing of access to new mining areas. The planning exercise was required to achieve the following objectives: 1. Minimise investment in FY2014 without compromising the future by mining ore from existing pits (Fobinso and AF Gap) and reclaiming ore from existing ore stockpiles; 2. Commence development of Eastern Pits as early as possible after July 2014; 3. Include new pits (Chirawewa and Bokitsi) not previously included in Ore Reserves; 4. Give priority to cash generation over marginal gold production; and 5. Preserve the capacity to expand pits in a higher gold price environment. Based on this work, the following pit development schedule was developed: https://media3.marketwire.com/docs/904344_graph_1015.pdf. ORE RESERVES Following completion of the above, mining consultant RPM was commissioned to complete an independent estimate of the Ore Reserves for the EGM as at 1 July 2013 in accordance with the requirements of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code, 2004 Edition). The Ore Reserves, which include material from seven open pits including Abnabna, Fobinso, Fetish, Chirawewa, Bokitsi, Esuajah North and Esuajah South plus stockpiles, are as follows: Table 3: EGM Proved and Probable Ore Reserves Contained Tonnes Grade Gold Category (Mt) (g/t gold) (oz) Proved 59.6 1.1 2,177,300 Probable 23.1 1.1 835,700 TOTAL 82.7 1.1 2,924,500 Notes: 1. Estimate has been rounded to reflect accuracy 2. All the estimates are on a dry tonne basis The Ore Reserve estimate for the EGM was based on actual operating performance and ongoing test work and applied the following criteria: 1. Proven and Probable Mineral Reserves found within the economic pit limits designed based on Measured and Indicated Mineral Resources; 2. Gold metal price US$1,200/ounce; 3. Key mining parameters include: a. Mining recovery 100%, mining dilution varies by deposit as result of block regularisation resulting in a range, due to multiple block models used, of between 3-12%; b. Overall pit slopes of 30 to 50 degrees inclusive of berms spaced at between 5m and 20m vertically and berm widths of 5m to 12m. These parameters were derived from ongoing geotechnical studies commenced by George Orr and Associates in August 2012; c. Pit ramps have been designed for the current 777 truck fleet and are set at a net 16m (single lane) to 26m (dual lane); d. Vertical mining advance has been set at 60 to 80m/year based on the size of the pit. 4. Ore cut-off grades are based on the gold price and mining parameters described in (2) and (3) above and are as follows: Table 4: Cut-off grades Material Type Gold Grade (g/t) Oxide 0.6 Transitional 0.5 Sulphide 0.4 5. Gold processing recovery ranging from 61% for oxide to 88% for fresh rock. 6. Processing throughput 7.5Mtpa. 7. Mining operating costs based on rates negotiated in November 2009 with mining contractor (African Mining Services) adjusted for historical rise and fall factors, currently at 25% for load and haul cost and 10% for other mining costs and additional US$2.15/t ore for crusher feed haulage from the Eastern Pits. The average life of mine mining cost is US$3.43/t of material moved. 8. Unit processing costs are assumed to be US$9.05/t of ore processed plus a further US$0.09/t of ore processed for refining costs. A General and Administration unit cost of US$2.82/t of ore processed has been assumed, which equates to approximately US$2 million per month. LIFE OF MINE PLAN Based on the Ore Reserves stated above, the production profile for the EGM for next five years is currently expected to be as follows: Table 5: LOMP Production Statistics LOMP Parameter FY2014 FY2015 FY2016 FY2017 FY2018 Avg(1,2) Ore mined (Mt) 5.3 7.7 9.7 9.4 7.4 8.7 Waste mined (Mt) 22.9 26.6 26.5 26.4 28.8 25.1 Strip ratio (t:t) 4.3 3.5 2.7 2.8 3.9 2.9 Ore processed (Mt) 7.5 7.4 7.5 7.5 7.5 7.5 Head grade (g/t) gold 1.0 1.2 1.2 1.1 1.2 1.1 Gold production (kozs) 200 240 240 230 245 230 Notes: 1. Assumes mining occurs over 9 years from 1 July 2013. 2. Assumes processing of ore over 11 years from 1 July 2013. Processing of low grade ore stockpile is scheduled to continue for a further 3 months beyond 30 June 2024 at a lower production rate and is not included in the above data. Compared to the previous LOMP for EGM, which was based on the 2012 Ore Reserve, the updated LOMP results in the following: - Tonnes of ore and waste moved - Down by 15% - Life of mine strip ratio - Down by 16% - Head grade - Steady - Contained gold in Ore Reserve - Down by 6% - Life of mine - Increased by 0.6 years to 2024 On a pit by pit basis, the technical parameters of each pit are as follows: Table 6: Comparison LOMP Production Pit 2012 LOMP(1,2) ------------------------------------------------------------ Waste Ore Grade Gold Strip (Mt) (Mt) (g/t) (koz) Ratio AF Gap 78.1 29.8 1.1 1,015 2.6 Fobinso 40.1 11.5 1.2 429 3.5 Sub-total 118.2 41.3 1.1 1,444 2.9 Fetish 53.7 15.8 1.1 576 3.4 Esuajah Sth 73.8 8.2 1.9 493 9.0 Esuajah Nth 32.5 17.1 0.9 501 1.9 Chirawewa - - - - - Bokitsi - - - - - ROM S/pile - 4.4 0.6 89 - TOTAL 278.2 86.9 1.1 3,109 3.2 Pit 2013 LOMP(1,3) ------------------------------------------------------------ Waste Ore Grade Gold Strip (Mt) (Mt) (g/t) (koz) Ratio AF Gap 63.4 27.5 1.1 954 2.8 Fobinso 30.6 9.3 1.1 330 3.6 Sub-total 94.0 36.8 1.1 1,283 2.6 Fetish 29.8 13.9 0.9 442 2.1 Esuajah Sth 56.2 6.9 1.7 382 7.2 Esuajah Nth 22.2 15.7 0.9 465 1.4 Chirawewa 11.2 2.9 1.1 106 3.8 Bokitsi 13.3 2.1 2.3 158 6.3 ROM S/pile - 4.4 0.6 89 - TOTAL 226.7 82.7 1.1 2,925 2.7 Notes: 1. Based on Measured and Indicated Mineral Resources only, adjusted for mining depletion to 30 June 2013. 2. Based on August 2012 Proved and Probable Ore Reserve; 0.4g/t and 0.5g/t cut-off, sub-blocks. 3. Based on the June 2013 Measured and Indicated Mineral Resource; Oxide - 0.6g/t cut-off; Transitional - 0.5g/t cut-off; Fresh - 0.4g/t cut-off, regular block. Applying the stated unit cost assumptions to this production profile, the forecast unit all-in site cash costs for the EGM are estimated to be as follows: Table 7: LOMP Costs(1) US$/oz Cost FY2014 FY2015 FY2016 FY2017 FY2018 LOMP Avg Mining 479 481 474 551 486 410 Processing 344 282 291 293 276 297 General & Admin. 118 95 95 96 88 91 Sub-Total 941 858 860 940 851 799 Royalty 79 82 82 78 78 79 Sustaining Capital 87 80 79 101 94 60 Total All-in Site Cost 1,107 1,020 1,021 1,119 1,022 937 Note 1: Before taking silver credits of US$5/oz into account . These estimated unit costs are based on the following assumptions: 1. Mining costs include the total cash cost of mining both ore and waste (including pre-strip) during the period. Mining costs are based on contracted rates negotiated in November 2009 with mining contractor, African Mining Services, adjusted for historical rise and fall factors (currently at 25% for Load and Haul cost and 10% for other mining costs) and an additional US$2.15/t ore for crusher feed haulage from the Eastern Pits. The average life of mine mining cost is US$3.43/t of material moved. 2. Unit processing costs are assumed to be US$9.05/t of ore processed plus a further US$0.09/t of ore processed for refining costs. This cost is based on actual costs adjusted to remove one-off costs incurred in recent periods that related to one-off maintenance events, electricity back-pay etc. 3. A General and Administration unit cost of US$2.82/t of ore processed has been assumed, which equates to approximately US$2 million per month. 4. Future costs do not include estimates of inflation, nor do they assume that the benefits of cost optimisation programmes being implemented across the EGM site will be realised; 5. Royalty is based on a US$1,200/oz gold price and assumes a 5% royalty paid to the Ghanaian government and a 1.5% royalty payable to Franco Nevada; 6. Sustaining capital expenditure is estimated at US$151 million for the remaining life of mine, or on average US$13.7 million per year for 11 years of processing. This estimate includes the cost of site rehabilitation net of equipment salvage value in the final year of the mine. The single largest item of forecast capital expenditure relates to the cost of compensating landowners for loss of crops, structures and livelihood as well as the cost of relocation housing. This accounts for slightly more than half of the sustaining capital estimate and includes expenditure associated with accessing open pits on both the western and eastern sides of the mining lease. The use of underground mining techniques on the Esuajah South Resource could result in a material decrease in the estimate. However, as the feasibility of using this mining technique has not yet been demonstrated, it has been assumed that open pit methods requiring relocation of infrastructure and dwellings will be applied. It is intended that the EGM LOMP will be reassessed annually taking into account any incremental Mineral Resources delineated during the preceding period and any revisions to design parameters (including, but not limited to, gold price and operating costs) in the design of the pit shells.
