additional diamond core drilling
------------------------------
The strong economics of the proposed development - including a pre-tax NPV of US$680.5 million and post-tax NPV of US$416.4 million - provide a strong foundation for the definitive Feasibility Study on the Obotan Project (see Figure 1), which is already underway and targeted for completion by the end of June 2012, paving the way for a development decision in the September 2012 Quarter.
Post completion of the FS, the financing, construction and development of the Obotan Project can proceed. This will be PMI's first gold operation in West Africa and, contingent on the outcomes of the FS, the Project development is planned to proceed in Q3, calendar 2012, with initial mine development activities scheduled to commence in Q1, calendar 2013 and targeting full production for calendar 2014.
The Obotan PFS, which was independently compiled by GRES a leading experienced engineering company of Perth, Western Australia, based on work by four leading international geological and engineering consultants, resulted in a life-of-mine production of 2.10 million recovered ounces of gold over an initial 11.2 years (inclusive of 1 year pre-strip operations).
This Project is based on a NI 43-101/JORC compliant estimate of combined Proven and Probable Mineral Reserves of 2.26 million ounces at 2.32g/t gold (1.06 million ounces at 2.36g/t gold in the Proven category and 1.20 million ounces at 2.28g/t gold in the Probable category).
Annual gold production is forecast at 205,600oz at an estimated life-of-mine total cash operating cost of US$690.2 per oz including royalties, refining costs and pre-strip mining, positioning the Obotan Project at the lower end of the global cash cost curve.
The estimated production profile is based on processing 3Mtpa of ore for 10 years with a total of 30.3Mt of ore mined. Initial capital costs are estimated at US$183.5 million, including a contingency of US$23.2 million. Deferred and sustaining capital is estimated at US$21.9 million.
The PFS was based on a gold price of US$1,300 per ounce, 5% discount rate and contract mining scenario, with the Project generating a pre-tax NPV of US$680.5 million and post-tax NPV of US$416.4 million. The pre-tax IRR is 42% and the post-tax IRR is 31% with a capital payback of 2.9 years from commencement of first gold production.
Commenting on the PFS results, PMI's Managing Director and CEO, Collin Ellison, said:
'Our focus is now moving on to complete the definitive Feasibility Study - the key elements of which actually commenced in the second half of last year and are already well underway. We are on target to complete the next resource estimate update before the end of February and the FS by the end of Q2, 2012, putting us in a position to make a development decision on Obotan in Q3, calendar 2012.'
'PMI has an objective of commencing plant commissioning in Q4, calendar 2013 and gold production by the start of calendar 2014. It is anticipated that the project will start pre-strip mining in Q1, calendar 2013, requiring the issue of tender documents to preferred contractors in Q1, calendar 2012. Furthermore, we shall also review the delivery times for key plant and equipment and if necessary place orders for their supply.'
'This timetable will enable PMI to join the ranks of leading West African gold producers by early 2014 . We are now well placed to make the transition from explorer to producer on an exciting project which has been significantly de-risked through the earlier successful mining that was carried out at gold prices less than US$350 per ounce.'
'Our target now is to identify and develop new shallow oxide resources within trucking distance of the Nkran processing plant at Obotan and the adjoining Asanko (Asankrangwa) concessions, as part of an increased regional exploration push the details of which will be announced in the near future.'
'With exploration ramping up at Obotan and across our regional tenement holdings at Kubi and Asanko, we are looking forward to a period of strong news flow from drilling as well as a further upgrade of the JORC/NI 43-101 resource base at the Obotan Project next month.'
'Finally, in order to facilitate the expansion of exploration activities PMI has recently introduced changes to its drilling fleet with the addition of two multipurpose Reverse Circulation (RC)/Diamond core (DD) drill rigs and one Rotary Air Blast (RAB)/AirCore drill rig complementing the existing dedicated diamond drill rig. The establishment of a dedicated sample preparation facility at Obotan in October 2011, operated by AMS/MinAnalytical, has also shortened the turn-around of assay results which is providing significant support to our expanded exploration drive.'

Economic Analysis
The economic analysis has been completed on behalf of Adansi and on the basis that Adansi is the 100% owners of the Obotan Project. It is noted that the regulations in Ghana stipulate a 'Net Profit Interest Royalty' of 10% be paid to the Government of Ghana at the same time as any dividends are paid by Adansi.
The proposed new corporate tax rate of 35% has been incorporated into the analysis together with the proposed new depreciation rates of 20% per annum. A proposed 10% windfall profit tax has not been included, as the basis for any such tax is not known.
A 5% royalty to the Ghana government and a further royalty of 2% to the vendor (Goknet Mining Company Limited) are also provided for.
A summary of the Project economic analysis pre-tax at various gold prices is as follows:

Mineral Reserves Used in the Mine Plan
(The reported Reserve estimate is shown in the following table:)
___________________________________________________

1. The SRK Mineral Reserve was estimated by construction of a block
model within constraining wireframes based on Measured and
Indicated resources.
2. The Reserve is reported at lower a cut-off grade of 0.5g/t Au,
which defines the continuous/semi-continuous mineralized zone
potentially amenable to the low grade, bulk tonnage mining
scenario currently being considered by PMI.
3. The grades and Reserve tonnes have been modified by a 95% mining
recovery and a 5% allowance for mining dilution at 0.0g/t gold.
4. At 93% metallurgical recovery for Oxide and Transitional material
and 94.5% metallurgical recovery for Fresh material was used in
defining the optimal pit shell
5. The Mineral Reserves are based on the October 2011 Mineral
resource reports for the Nkran, Adubiaso, Abore and Asuadai
deposits
6. All tonnes reported are dry tonnes
7. The base case pit optimization utilized a US$1,300/oz gold price
8. Mineral Reserves are reported in accordance with the NI 43-101 &
JORC.
Mining Plan
It is proposed that the Obotan Project will initially be an open pit mining operation providing ore at a nominal rate of 3Mtpa during the process plant operating life of 10.2 years following a 1-year waste pre-strip operation.
Annual mine production of ore and waste will peak at 35.0Mtpa, with a life-of-mine stripping ratio of 7.6. The base case pit design was optimized at US$1,300/oz gold and a mine recovery of 95% and mining dilution of 5% at a grade of 0.0g/t.
A mining contractor is proposed for earth moving activities. All deposits would be mined utilizing conventional truck and shovel methods.
Approximately one year of waste stripping will be required at Nkran to expose sufficient ore to maintain a constant ore feed rate of 3.0Mtpa. The cost of this pre-strip is estimated at US$68.3m and is included in mine operating costs.
The overall mining sequence is based on commencing operations at Nkran followed by mining the satellite deposits at Adubiaso, Abore and lastly Asuadai (see Figure 2). The opening up of each deposit is to be developed to optimise ore feed to the mill while maintaining throughput of 3.0Mtpa.
Metallurgy and Mineral Processing
Metallurgy
The PFS has been based on testwork undertaken by the previous operators, Resolute Mining Ltd ('Resolute') plus operational data from 5-years of production. New metallurgical testwork is being undertaken by PMI, supervised by GRES to validate the earlier testwork and operating results. The original Resolute testwork was carried out by AMMTEC Pty Ltd, AMDEL Ltd, Supaflow Technologies Pty Ltd, Analabs Pty Ltd and METCON Research Inc. under the supervision of Lycopodium Pty Ltd and Orway Mineral Consultants as part of the Lycopodium Feasibility Study for Resolute.
Resolute's operating data indicates overall recovery of 93.5% for oxide ore and 93.1% for primary ore.
Mineral Processing
The Obotan carbon-in leach ('CIL') plant is designed to nominally crush and mill 3.0Mtpa of primary ore with a maximum wet plant capacity of approximately 3.8Mtpa to allow for higher throughput when treating soft oxides.
The process includes single stage jaw crushing, a SAG and ball mill in closed circuit with hydro-cyclones, pebble crusher, a gravity circuit and a single stage pre-leach and seven stage CIL circuit. The process plant will be located proximal to the Nkran deposit where 80% of the Reserves are located. Maximum haulage distance for ore from the satellite deposits will be 15km.
The process plant design allows for a gravity recovery of gold of 40%. This recovery is similar to that achieved by Resolute. The proposed process flow sheet is similar to that employed by Resolute.
Infrastructure
The PFS has assumed the cost for the construction of new administration buildings, temporary and permanent mine village facilities, a new 30km 116Kv power line, and the rehabilitation and expansion of the existing borefield.
The recent agreement with the Anglican Church (as announced 20 December 2011) to purchase the original Resolute's administration and mine village buildings was not incorporated into the PFS. The refurbishment of these facilities is expected to cost marginally more than the new facilities but will provide immediate access during development and for current exploration activities.
Sensitivities
The key sensitivities are set out below:
____________________________________
|Factor |Change|Effect on NPV|
|_______________|______|_____________|
|Gold Price | +10% | +28% |
|_______________|______|_____________|
|Operating Costs| +10% | -15% |
|_______________|______|_____________|
|Capital Costs | +10% | -4% |
|_______________|______|_____________|
|Ore Grade | -10% | -28% |
|_______________|______|_____________|
When the Company examined a sensitivity model from the base case, whereby the operating costs were increased by 10%, capital costs increased by 10% and grade reduced by 10%, the resulting after tax NPV was still a strong $221.8 million.
Project Development Plan
PMI had already commenced various FS work in Q3/Q4, 2011. This FS work entailed geotechnical and metallurgical drilling and laboratory analysis, environmental baseline monitoring and socio-economic evaluation. A new resource estimate of the Obotan deposits is scheduled for completion before the end of February and will form the basis for the FS mineral reserves and mine production schedule. The Company is now focused on completion of the Obotan Gold Project FS by the middle of 2012.
