REO PROJECT (BURKINA FASO)

The Reo Project is located in Burkina Faso, approximately 150km by road west of the capital Ouagadougou. The project comprises five granted exploration permits previously held by Newmont and two permit applications made by Bureau de Consultations et des Services (BCS). The exploration permits and permit applications cover an aggregate area of 1,166km. Middle Island acquired a 100% interest in all exploration permits and applications from Newmont Ventures Limited (Newmont) for the equivalent of US$2.5 million in fully paid Middle Island shares (10.15 million shares), issued to Newmont on listing.

The project area straddles the structurally complex junction of the Boromo and Houndreenstone belts where thrusted against the central Burkina granitoid massif. The geology comprises a typical greenstone succession of felsic to mafic volcanics and derived sediments, regionally metamorphosed from mid to upper greenschist facies, which are intruded by syntectonic (belt or Dixcove type) granitoid stocks. The project is located 90km north of the historic Poura gold mine (1.5Moz), 100km northeast of the Mana deposit (3Moz), currently being developed by Semafo Inc., and immediately northwest of the Perkoa volcanogenic massive sulphide (VMS) zinc deposit, also being developed by Glencore International plc and Blackthorn Resources Limited.

The Reo project area was originally selected by Newmont on the basis of a regional (cratonic) study. Between 2007 and 2010, gold mineralisation was defined by Newmont at six main prospects, variously referred to as Morley, Goumi, Dassa, K4, K5 and East, and a further VMS prospect is located in the southeast portion of the Bissou permit application. The principal gold prospects are located around the margins of the Didyr granitoid, with the two more significant prospects, Morley and K4/K5, located in classic pressure shadow sites at opposing ends of the stock as shown in the figure below.

The more advanced Morley Prospect lies immediately west of the village of Didyr and comprises a 3.25km x 0.8km soil anomaly with a peak value of 500ppb Au. No outcrop is exposed at the prospect, as it is largely veneered by transposed to transported soils and laterites. Newmont variously employed trenching, rotary air blast (RAB), aircore, reverse circulation percussion (RC) and limited diamond core (diamond) drilling to resolve the mineralised zone structure and geometry, ultimately defining what appears to represent a series of broad, stacked, parallel east-west trending lodes that dip north.

Previous exploration at Morley generated numerous broad, high grade gold intersections, summarised in the table below, however some of these intercepts are derived from holes drilled oblique to the interpreted mineralised zones and therefore exaggerate their likely true width, which is interpreted to approximate 6m to 12m.

There is no evidence of artisanal mining activity at the Morley Prospect, presumably due the extremely fine nature of the gold mineralisation.

It is important to note that the northern mineralised zone at Morley extends eastwards into the outskirts of Didyr village, potentially requiring the relocation of some scattered residences should an economic discovery be made.

Initial trenching and RC drilling completed by Middle Island at the Morley Prospect has confirmed the width and tenor of mineralisation identified by Newmont, with better results tabulated below.

The distribution of results to date confirms the interpreted mineralised zone geometry and validates the new drilling orientation (-60o to 180o grid). The width and tenor of intercepts is consistent with that encountered at surface in historic and recent trenching as well as modelled drilling completed by Newmont. The results received for Morley appear consistent with stacked, broadly east-west striking, moderately north-dipping veins and lodes, and the current drill orientation is providing near true widths of mineralisation.

A RAB drilling campaign is planned to assess the full extent of the stacked lodes along the axis of deformation (granite contact) within the Morley-Goumi dilation zone in the coming field season, prior to the commencement of pattern RC and diamond drilling.

The other more significant target at the Reo Project is the K4/K5 Prospect, located at the southern extremity of the Didyr granitoid. The prospect comprises a cohesive 4km x 2.5km soil anomaly with peak values >1,000ppb (>1g/t) Au. Again little geology is exposed, but the area is predominantly veneered by transposed soils and laterite.

The prospect was previously only tested by sparse, shallow aircore drilling on 400m spaced lines with a dominant hole spacing of 100m. The most significant intersection of 18m at 2.51g/t Au (to end of hole) was returned from hole NAC027 within the southern-most, K5, portion of the anomaly. Subsequent limited RC drilling by Middle Island returned a best intercept of 13m at 2.23g/t Au (also to end of hole) some 30m distant from the original Newmont intercept. Logging and modelling of these intercepts suggests that mineralisation is associated with a broad east-west trending zone of intense sheeted to massive quartz-carbonate veining with intensely sericite-altered metasediment that veneers the shallowly south-plunging extremity of the Didyr granitoid.  A 5,000m RAB drilling programme has just been completed over the K5 portion of the target in an effort to confirm the morphology and tenor of the mineralised zone prior to RC drilling.

Some 10,000 illegal artisanal miners were present on the K5 portion of the K4/K5 Prospect, exclusively working lateritic material over an area 2km wide by 1km long. However, in May 2011 the Burkina Government closed the operations down due to safety concerns following a series of ground collapses.  The presence of intense artisanal mining activity over such a wide area clearly demonstrates the potential of the K4/K5 Prospect.

The Morley and K4/K5 targets individually and/or collectively represent the potential to fulfil the Company's primary objective, and exploration is primarily focussed on achieving this objective.

Aircore drilling at the K4/K5 Prospect appears poorly oriented with respect to the mineralised structures and potential exists to define significant mineralisation with appropriately located and oriented drilling.

In addition, an extensive program of geochemical auger drilling has commenced, primarly focussed on a major shear zone recently defined over a 50km strike length.  This programme has the potential to identify other significant prospects in transposed and/or transported regolith regimes within what is a substantial and highly prospective tenement holding.
