PMI Gold Corporation (TSX-V: PMV) (ASX: PVM) is pleased to report further assays have been received from resource drilling at its 100% owned Obotan Gold Project in Ghana, West Africa (Figure 1). The results from 46 diamond drill holes representing 6,395 samples from 11,843 metres of drilling have been received. These results are from all four deposits in the Obotan Gold Project. All drill holes were designed to test the down dip extension of mineralization on the four deposits (Nkran, Adubiaso, Abore and Asuadai) in the Obotan Gold Project. The results continue to reinforce the resource estimate and block models for the various deposits and continue to support the potential of the project. (Figure 2).
These results will be included in a new resource estimate due in the March quarter, 2012 for the definitive Feasibility Study. The definitive Feasibility Study is targeting completion by June 2012.
To date, PMI Gold has completed 311 diamond drill holes totaling 80,218 metres at the Obotan Project.
Resource expansion and exploration drilling continues within the Obotan Project area with one multi-purpose RC/Diamond core drill rig and one RAB/Aircore drill rig testing multiple oxide targets. One additional multi-purpose RC/Diamond core drill rig is completing a hydrogeological drill program for the evaluation of pit wall drainage and the future expansion of the existing Obotan process water supply.
With the commencement of operations of the Obotan preparation laboratory, established for the exclusive use of PMI Gold by AMS/MinAnalytical Laboratory Services Australia Pty. Ltd., the provision of assay results has improved considerably on the local commercial laboratories resulting in an average turn-around time for sample results of 20 days. This is enhancing the quick interpretation of PMI's drilling activities and allows more informed decisions to be made during our exploration drilling programs.
Drilling Results at Obotan Project
Assay results for 12 diamond drill holes were received from Nkran. The results confirm the high grade gold mineralization intersected in the previous drilled hole results. It also confirms the known mineralization, which is formed within an eastern lode, western lode and central adjoining stockwork complex. Mineralisation is associated with highly altered greywackes, brecciated phyllite, diorite and quartz/albite veins with arsenopyrites. Drill and assay results from deeper holes confirm that the Nkran mineralization is open at depth and to the south.
Significant results from Nkran include:
|- NKR11-069||72m at 4.25g/t from 318m||including 6m at 7.68g/t from 349m|
|- NKR11-085||60m at 3.47g/t from 440m|| including 6m at 14.00g/t from 480m, and
|2m at 17.75g/t from 490m|
|- NKR11-086||20m at 2.46g/t from 541m|
|- NKR11-089||12m at 2.27g/t from 320m||including 2.4m at 8.92g/t from 320m|
|- NKR11-089||63m at 1.22g/t from 345m||including 5m at 4.72g/t from 367m|

|including 2.9m at 20.04g/t from 466.1m|
|- NKR11-091||28m at 4.21g/t from 558m|| including 15m at 5.56g/t from 558m, and
|3m at 14.16g/t from 564m|
|- NKR11-092||10m at 3.42g/t from 359m|

|- NKR11-093||36m at 1.63g/t from 619m|
Assay results from 11 diamond drill holes confirmed that high grade gold values continued at depth. The mineralisation occurs in jogs within a NE-SW striking shear vein system in sub-vertically dipping interbedded greywackes and phyllites within an intrusive. The down dip extension of mineralization within the resource area has been confirmed with the assays received for this report. Hole ADP-038 also confirms mineralization is still open to the North.
Significant results from Adubiaso include:
|- ADP11-032||3m at 3.13g/t from 118m|
|- ADP11-038||5.2m at 8.53g/t from 98.8m||including 3m at 13.10g/t from 100m|
|- ADP11-039||14m at 2.68g/t from 203m||including 3m at 7.2g/t from 208m|
At the Abore deposit, assays from 2 diamond drill holes were received. Values reported were low grade results. Gold mineralization at Abore is located within granitoids and at the contacts with the meta-sedimentary rocks. Mineralization in Abore is open to the north and there is the potential to increase the resource base in Abore.
Assays were received for 21 drill holes at Asuadai deposit which returned medium to low grade review. Assays from hole ASP-044 indicate that mineralization in the southern and northern parts of the deposit is internally continuous.
Significant results from Asuadai include:
|- ASP11-043||4.42m at 3.33g/t from 121.3m||including 1.16m at 11.63g/t from 121.3m|
|- ASP11-055||4m at 2.58g/t from 103m|
|- ASP11-058||49m at 1.73g/t from 146m||including 1m at 10.38g/t from 165m, and|
|including 1m at 28.22g/t from 190m|
|- ASP11-059||9m at 2.75g/t from 188m|
|- ASP11-059||6m at 5.20g/t from 218m|
|- ASP11-060||12m at 6.69g/t from 143m||including 3m at 23.68g/t from 152m|
|- ASP11-061||25.9m at 1.08g/t from 3m|
Full drilling results are available in Table 1.
On 13 October 2011, PMI released its interim JORC/NI43-101 resource upgrade for the Obotan Gold Project as summarised below:
|- Measured Resources||- 14.67 million tonnes @ 2.66g/t for||- 1.22 million Au ounces|
|- Indicated Resources||- 27.50 million tonnes @ 2.32g/t for||- 2.00 million Au ounces|
|- Inferred Resources||- 17.54 million tonnes @ 2.35g/t for||- 1.29 million Au ounces|
The SRK Consulting Resource estimate was based on a 0.5 g/t Au lower cut-off grade for each deposit. The resource estimate results are provided in further detail in Table 2.
The robustness of the interim resource estimate provides confidence that potential remains for future increases in resources. All Obotan deposits remain open at depth and there is further scope for strike extensions. The interim resource estimate was incorporated into the Pre-feasibility study mine plan, the results of which were released on 12 January 2012. The JORC/NI43-101 Pre-feasibility Study estimated a Proven and Probable Reserve for the Obotan Gold Project of 30.3Mt at 2.32g/t for 2.26Moz of gold, as summarised in Table 3.
The Company lodged its NI43-101 Resource Estimate Technical Report on 28 November 2011 and its Pre-feasibility Study Technical Report on 13 February 2012, both of which are available at www.sedar.com.

Competent Person Statement
The information in this announcement that relates to Exploration Results is based on information compiled by Collin Ellison, who is employed by PMI Gold Corporation. Mr Ellison, who is a Member Institute of Material, Minerals and Mining of UK, a 'Recognised Overseas Professional Organisation' (ROPO) included in a list promulgated by the ASX from time to time, has sufficient experience which is relevant to the style of mineralization and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2004 Edition of the 'Australasian Code for Reporting Exploration Results, Mineral Resources and Ore Reserves'. Mr Ellison consents to the inclusion in this report of the matters based on his information in the form and context in which it appears. Scientific and technical information contained in this news release has been reviewed and approved by Collin Ellison, C.Eng. a "qualified person" as defined under National Instrument 43-101. Field work was supervised by Thomas Amoah (VP-Exploration). HQ and NQ core was logged, sawn and sampled on site, with half samples sent to SGS Laboratory in Tarkwa, and analyzed for gold by fire assay-AA on a 50 gram sample charge or by screened metallics AA finish. Internal QC consisted of inserting both blanks and standards into the sample stream and multiple re-assays of selected anomalous samples. Where multiple assays were received for an interval, the final value reported was the screened metallic assay if available, or in lieu of that the average of the other results for the interval. Results from the QC program suggest that the reported results are accurate. Intercepts were calculated with a minimum 0.5 g/t Au cut off at the beginning and the end of the intercept and allowing for no more than three consecutive metres of less than 0.5 g/t Au internal dilution. True widths are estimated at from 60% to 70% of the stated core length.
Obotan Resource & Reserve Estimate :
Information that relates to Mineral Resources at the Obotan Gold Project is based on a resource estimate that has been carried out by Mr Peter Gleeson, and information that relates to Mineral Reserves at the Obotan Gold Project is based on a reserve estimate that has been carried out by Mr Duncan Pratt, both full time employees of SRK Consulting, Australia. Mr Gleeson is a Member of the Australian Institute of Geoscientists (MAIG) and Mr Pratt (CP Mining), is a Member of the Australasian Institute of Mining and Metallurgy (MAusIMM).
