"The Wa Gold Project Feasibility Study confirms the Project's technical and financial viability and enables Azumah to commence applications for key mining, environmental and other approvals required to initiate development," Azumah Managing Director, Mr Stephen Stone, said.

"The Study also allows us to advance discussions with our short-list of possible providers of various forms of project finance."

"We envisage making a development decision in early 2013 by which time the expected delivery of additional Mineral Reserves will have placed the Project on an even stronger footing."

"With $20 million in cash and listed investments, Azumah remains well positioned to continue delivering excellent exploration results in parallel to advancing its plans to establish the first commercial-scale gold mining operation in Ghana's emerging and very prospective northwest gold province."

NB: All amounts in US$ unless specifically stated and all financial analysis based on 100% project ownership.  Rounding of numbers may result in minor inconsistencies in tables.

Gold explorer and developer Azumah Resources Limited (ASX: AZM; TSX:AZR) is pleased to announce the completion of a Feasibility Study (FS) and a maiden Mineral Reserve which represents an important first step in developing its 100%-owned Wa Gold Project in northwest Ghana (the 'Project') (Figure 1).

The FS has confirmed that the Project is technically and commercially viable with current Mineral Reserves of 430,000oz gold supporting an initial six years production from a planned nominal one million tonne per annum gravity / carbon-in-leach (CIL) plant.

The Mineral Reserves were estimated by independent engineers, Coffey Mining Limited, based on the Kunche, Bepkong and Julie gold deposits (Table 1).

Table 1: Mineral Reserve Summary

Mineral Reserve Summary
(As of 21st Aug 2012) Proved Probable
Tonnes (Mt) Grade (g/t Au) Tonnes (Mt) Grade (g/t Au)
Bepkong 1.7 1.9 0.2 2.0
Kunche 2.3 2.1 1.6 1.6
Julie - - 1.0 2.4
Total 4.0 2.0 2.8 1.9

Importantly, the completion of the FS enables Azumah to commence applications for key mining, environmental and other approvals required to initiate development as well as formalise discussions with a short-list of possible providers of various forms of project finance.

Azumah expects that a development decision can be made in the first half of 2013 by which time the planned delivery of additional Mineral Reserves will have placed the Project on an even stronger footing.

Mineral Resource and Mineral Reserve Updates

Recent exploration and drilling provide clear evidence that Mineral Resources and consequently Mineral Reserves will continue to grow to extend mine life beyond the initial base now established to underpin a start-up operation.

Azumah anticipates providing an update of Mineral Resources in late 2012 / early 2013 that will benefit from the results of recently completed infill and extensional drilling at the Kunche, Bepkong and Julie deposits (refer releases dated 19th June 2012 and 19th July 2012)(Table 2).

A Mineral Reserve upgrade, scheduled for early 2013, is planned to extend mine life with a commensurate positive impact on financial returns.  This update will benefit from infill drilling designed to convert Mineral Resources to Mineral Reserves in the immediate vicinity of designed pits and from excellent recent drilling results from the Julie deposit and Aduane prospect (refer ASX releases 29th February 2012 and 19th July 2012).

The Collette Mineral Resource, currently 79,000 oz, was not considered a part of the FS but is being advanced to determine if it will also add to existing reserves, as are several other prospects.

More broadly, and a key asset of Azumah, is its commanding control position of over 3,100km2 of the prospective Wa-Lawra Birimian greenstone belt complemented by its 17% interest in neighbouring explorer, Castle Minerals Limited (ASX: CDT), which has more than 10,000km2 of additional tenure in the region (Figure 1).

With some $20 million in cash and listed investments, Azumah remains well positioned to maintain its focused exploration programmes, leveraging off its excellent site infrastructure that includes a fully serviced 50-man exploration headquarters at Kalsegra and a recently commissioned on-site sample preparation laboratory providing a much improved average 25 day sample-to-assay turnaround.

NB:  The Mineral Resources shown in Table 2 are inclusive of the Ore Reserves that are stated in this release.

Mining Schedule and Key Outputs

The gold recovery plant will be located adjacent to Azumah's Kunche flagship deposit with initial ore sourced from the phased, contractor based, open-cut mining of the Kunche, Bepkong and Julie deposits providing a robust first year head grade of 2.5g/t Au and an average of 2.2g/t Au for the first four years of production (Table 3, Table 4 and Graph 1).

Table 3:  Key Outputs

  Units Year 1 Years 1 to 4 Life of Mine
Average Process Plant Throughput Mtpa 1.23 1.12 1.13
Feed Grade Processed g/t 2.5 2.2 2.0
Gold Recovery % 93.8% 93.3% 92.4%
Strip Ratio - Waste to Ore   4.1 5.1 4.9
Annual Gold Production oz 92,000 74,000 66,000
Total Mining Cost $/t mined 3.84 4.05 4.67
Process Plant Cost $/t processed 14.24 16.26 16.00
Administration Cost $/t processed 3.88 4.25 4.19
Site Cash Cost $/oz 624 782 802

Accelerated production of 92,000oz during the first year is achieved from the processing of higher grade, softer oxide ore. The first four years of open-cut mining produce an average 74,000oz gold per annum from the treatment of mill feed averaging 2.2g/t Au at a strip ratio of 5.1:1.

The final months of gold production are from the treatment of stockpiled material but it is expected that this material will be deferred and replaced with additional and higher grade Mineral Reserves as they are progressively defined.

Current mining schedules have the Julie ore being mined and transported 80km to the Kunche plant, after the completion of mining at Kunche and Bepkong, at a transport cost that equates to approximately 0.3g/t Au. Whilst Julie ore is relatively high grade, the transport costs impact on Mineral Reserves.  Hence, Julie has been scheduled towards the end of the current mine life. This also gives the opportunity for a possible second stand-alone project to be established in the longer term, subject to exploration success.

Table 4: Summary by Deposit

  Ore Mined Strip Ratio Ore Grade Contained Gold
  Tonnes (million)   (g/t Au) (Oz)
Kunche 3.9 5.5 1.9 238,000
Bepkong 1.9 4.4 1.9 117,000
Julie 1.0 3.8 2.4   74,000
Total 6.8 4.9 2.0 430,000

Total site cash operating costs (C1) over the life of the maiden Mineral Reserve average $802 per oz (ex 5% government royalty), with a first year C1 cash cost of  $624 per oz.

Rising operating costs, and in particular a 45% escalation in mining costs since the FS was commenced, have had a negative impact on Mineral Reserves and overall Project returns.  However, Azumah holds the view that these costs may have now stabilised


Project oxide, transitional and primary ore types all have excellent metallurgical characteristics with overall gold recoveries averaging 92.4% over the present life-of-mine, whilst Julie ore types average 88%.  Flowsheet design and modelling incorporated separate considerations of each ore type at each deposit. The ore requires a medium grind of 75 microns.

Establishment Capital Costs

Total project establishment capital of $144M is consistent with earlier guidance levels and is inclusive of all plant, infrastructure, owner's costs, contingency, EPCM, first-fill of reagents and pre-production mining works.  Import duties on equipment have been included in capital cost estimates but no estimates have been made for VAT and withholding tax payments (Table 5).

Financial Summary

The pre-tax Project Net Cash Flow, NPV and IRR are $148M, $82M and 31% respectively (8% per annum discount rate, $1,600 per oz gold realisation price) and is based on 100% equity financing i.e. no interest cost.  Pits were optimised using a gold price of $1,300 per oz.

After taking into account a 5% gross government royalty, 35% company income tax and accumulated tax losses, the post-tax Net Cash Flow, NPV and IRR are $81M, $34M and 18% respectively with payback of less than three years (Table 6).

Table 6: Financial Summary

  Net Cash Flow NPV @ 8% IRR
  (millions) (millions) (%) (Years)
Site Project Return - Pre Royalties & Income Tax 148 82 31 2.4
Project Return - Post Royalties and Income Tax   81 34 18 2.9

Sensitivity analysis has shown that increasing Mineral Reserves by the equivalent of another Bepkong deposit (117,000oz at 1.9g/t Au) would increase post-tax Net Cash Flow by 65% to $134M and the NPV and IRR to $63M and 23% respectively as well as provide pit design, scheduling and other operational benefits.

Excellent Operating Environment

The Project benefits from excellent road and air access, plus continually improving local and regional infrastructure, including grid power which the Ghana power infrastructure utility, Gridco, has commenced upgrading to the Project's requirements.

Ghana's Upper West region is only moderately populated, has no major industry and generally relies on subsistence farming.  The Project is likely to bring many benefits to the area.

Importantly, there are no communities in the vicinity of the planned mining area that require relocation.  The process of land and crop surveying as a prelude to the formal farm compensation process, as required under the Ghana Minerals and Mining Act, has commenced and is now under the auspices of Azumah's newly appointed General Manager - Community.  Several community and other stakeholder consultation meetings have already been held.

Azumah's Draft Environmental and Social Impact Study has also been submitted to the Ghana Environmental Protection Authority.

Ghana has a long tradition of gold mining and is now Africa's second largest gold producer with several World-class gold mines in operation and four new mines established in the past year.  These are supported by a myriad of mining services and facilities available in-country and a well-trained and educated workforce. It has a strong economy and is ranked as one of the World's top ten fastest growing economies. Ghana has a long history of stable government and peaceful transitions to new democratically elected governments.

Timetable and Implementation

Subject to the timing of the receipt of key permits and the financing of the Project, the Project construction programme of 17 months could see it be in production by late 2014.

GR Engineering Services Ltd has completed a review of the Feasibility Study and the overall Project, with no issues identified. It is now on stand-by to commence the front-end engineering and design ('FEED') phase.
