Steven Poulton, Chief Executive of Altus, commented:
'Exploration is being accelerated at the Company's Tabakorole gold project in southern Mali under the JV with Glomin. Our field teams have commenced a ground magnetic programme which targets potential structural extensions to the historical resource, in an area where previous soil sampling returned encouraging results. Results from this survey will be analysed alongside those of the ongoing aircore drilling and the historical data, in order to guide the next phases of drilling under the JV. The aircore programme is progressing well, with over 1,100m completed to date of the planned 2,000m. We look forward to updating shareholders on the results from exploration at Tabakorole in due course.'
Tabakorole Project: Ground Magnetic Programme
The high-resolution ground magnetic programme is comprised of 163 NE-SW orientated lines spaced 50m apart for a total 520 line kilometres and covering an area of 25km2. Survey lines are orientated perpendicular to the strike of the NW to WNW striking FT deposit, as well as structures identified from historical airborne magnetic data. The Company's field team are using an in-house GEM Systems Overhauser Magnetometer. Processing of the data and QA-QC will be performed by Terratec Geophysical Services GmbH & Co. (Germany). Results of the programme will guide a follow up regolith sampling and potential drilling of the highest priority targets.

Tabakorole Project: Location
The 100 km2 Tabakorole project is located in southern Mali, approximately 280 km south of the capital city of Bamako. The Project sits on the Massagui Belt which hosts the Morila gold mine (operated by Barrick NYSE:GOLD, TSX:ABX), located approximately 100 km to the north. The Project is 125 km southeast of the Yanfolila gold mine (operated by Hummingbird AIM:HUM) and 100 km east of the Kalana gold project (operated by Endeavour Mining TSX:EDV).
Tabakorole Project: Geology
Tabakorole comprises a 2.7 km long shear zone which is up to 200m wide, hosted in the Archaean and Birimian aged Bougouni Basin of the Man Shield of southern Mali. The geology is dominated by clastic sediments cut by northwest trending deformation zones which host gold mineralisation. At least two, possibly three, Eburnean deformation events are believed to have affected the geology of Tabakorole.
The Project hosts the FT prospect which is comprised of mylonites, sheared diorite, gabbro, mafic dykes and late stage felsic dykes, within a folded and deformed metasedimentary package of meta-siltstone, meta-wacke and meta-sandstone. Gold mineralisation within the FT prospect is typically associated with 3-5% disseminated sulphides, notably pyrite, arsenopyrite, pyrrhotite and locally chalcopyrite. Mineralisation is locally most favourably associated where structures cut gabbro and along lithological contacts with gabbro.
Tabakorole Project: Historical exploration
The Project was discovered by a regional soil sampling programme completed on a 500m x 100m grid by BHP in the early 1990s. Since 2003, a total of 28,912m of diamond drilling, 31,943m of RC drilling, 6,577m of auger drilling and 60,676m of air core drilling have been completed, in addition to 1,400 line km of airborne geophysics. A selection of drill intersects from Tabakorole is shown in Table 1.
Following the completion of the 2007 historical mineral resource estimate, 58 RC holes (5,492m) were completed within and along strike of the FT prospect in 2010. Results included 6.05 g/t Au over 18m from 12m (10FLRC-12A) and 2.53 g/t Au over 24m from 48m (10FLRC-01A).

Tabakorole Project: Historical resource
The Tabakorole project hosts a historical mineral resource estimate as shown in Table 2. The historic resource comprised of 240,000 oz Au (7.88 million tonnes at 0.94 g/t) in the Indicated category and 350,000 oz Au (10.55 million tonnes at 1.03 g/t) in the Inferred category. The key assumptions, parameters and methods used to prepare this historical estimate are:
- A block model constructed using the Inverse Distance Squared method
- Block sizes of 10m X 25m X 5m in the easting, northing and RL directions
- The block model was estimated in 6 passes at 25m, 50m and 100m ranges
- Pass 1 & 2 represent spacing of 25m X 50m used to determine the Indicated portion of the resource
- Pass 2, 3, 4, 5 and 6 were used to estimate the Inferred portion of the resource
- 3 samples minimum were used to estimate any one single block
- Sample hierarchy:
- Bulk screen assays took precedent over regular assays
- Diamond drilling assays took precedent over Reverse Circulation drilling assays
- Air Core drilling was not used in the resource estimation
- Assays were top cut to 10 g/t gold (based on 99.5% on the cumulative frequency curve)
- Resources were reported at a 0.5 g/t gold cut off
The historic resource was prepared in accordance with NI 43-101 by H. Andrew Daniels, Consulting Geologist, P.Geo in a report entitled 'Technical Report on the Mineral Resource Update, June 2007 FT Project Mali, West Africa', dated July 27, 2007 and filed on SEDAR on July 27, 2007 by North Atlantic Resources Ltd. A Qualified Person has not done sufficient work to classify this historical estimate as current mineral resources and Altus is not, therefore, treating this historical estimate as a current mineral resource. However, it remains relevant to the Project and Altus believes it is also reliable. To verify this historical estimate so that the resource can be considered current, Altus would be required to contract a qualified and independent consultant to review historical drilling data and prepare a resource estimate in accordance with NI 43-101.

Tabakorole Project: New targets defined from historical data
The Company has completed a comprehensive review of the historical exploration data on the Project. A number of priority drill targets have been defined both within the main NW-SE trend of the existing FT prospect as well as potential extensions to the northeast. Several historical drill holes intersected mineralisation off the main trend of the FT prospect, including 12m at 3.40 g/t Au (06FLRC-01) and 28m at 1.01 g/t Au (06FLRC-04) which represent priority areas for follow up.
Six hundred metres to the south of and parallel to the FT prospect, a new prospect which is approximately 2.5 km long has been defined from historical airborne magnetic data. Elsewhere on the Tabakorole licence a number of priority targets for follow up trenching and auger drilling have been defined by the historical geophysical and surface geochemical data. The next phase of work at Tabakorole is expected to include drilling across new targets, as well as further resource definition drilling.
Cautionary note regarding historic data
Readers are cautioned that the data on Tabakorole as referred to in this written disclosure is historical exploration data that has not been verified by a Qualified Person. Not all historical samples are available and Altus does not have complete information on the quality assurance or quality control measures taken in connection with the exploration results, or other exploration or testing details regarding these results.
The potential tonnages and grades described in this release are conceptual in nature and are based on previous drill results that defined the approximate length, thickness, depth and grade of the portion of the historical resource estimate. There has been insufficient exploration to define a current resource and the Company cautions that there is a risk further exploration will not result in the delineation of a current mineral resource. The historical data should therefore not be relied upon until the Company can confirm them.
The technical disclosure in this regulatory announcement has been read and approved by Steven Poulton, Chief Executive of Altus. A graduate of the University of Southampton in Geology (Hons), Steven Poulton also holds a Master's degree from the Camborne School of Mines (Exeter University) in Mining Geology. He is a Fellow of the Institute of Materials, Minerals and Mining and has over 20 years of experience in mineral exploration and is a Qualified Person under the AIM rules and National Instrument 43-101 Standards of Disclosure of Mineral Projects of the Canadian Securities Administrators.
