Golden Hill Project (BOE 100%)

The Golden Hill Project is located 240km southwest of Ouagadougou, within the Houndé Greenstone Belt of Burkina Faso (Fig. 1). The project consists of three contiguous exploration permits (Baniri, Intiedougou, and Mougue) that cover a total area of 470km². Access is all year round off the Ouagadougou-Bobo Dioulasso highway via a well maintained lateritic gravel road. Boss Resources Limited owns a 100% interest in the project.

The Golden Hill permits cover a NNE-trending strip of highly prospective Birimian Greenstones that contain numerous NNE and NW-trending gold bearing shear zones and intrusive units (Fig. 2). Equivalents to the younger Tarkwaian Group sediments present in the eastern part of the project area are typically proximal to major structures and are spatially coincident with many giant gold deposits throughout the world.

Gold Mineralisation

The Houndé Greenstone Belt hosts a number of significant gold deposits including the 180,000 ounce per annum Mana gold mine (6.0 million ounce project) located only 75km to the north of the Golden Hill Project, and the 430,000 ounce Bondi project just 11km to the SW of the Mougue permit.

Previous regional soil geochemistry and drilling programs completed by Orezone Resources Inc. identified the presence of significant gold mineralisation within the project area (Fig. 3-8). A drill hole, trench and surface geochemistry database has been compiled from the Orezone data with a first pass validation completed.

Several phases of RC and diamond drilling by Orezone within the Intiedougou permit delineated NNE-trending, east dipping ore zones hosted by syenite intrusives within intermediate volcanic units (A Zone, B Zone), and WNW-trending, south dipping ore zones associated with quartz veined intermediate to mafic volcanics and felsic intrusives (C Zone, Peksou). Fifty two (52) Reverse Circulation and diamond drilling intercepts greater than 20 gram metres have been identified from within the Golden Hill Project historic drilling data (Fig. 4-8). Best results included:

8m @ 3.4g/t Au from 32m

A Zone, B Zone, C Zone, Peksou, Pekperine, and Ville7 Prospects are all located within a 6km x 1km +30ppb Au soil anomaly. Large gaps (up to 500m wide) in the previous drilling and untested high grade plunging ore shoots expected at the intersection of the two styles of gold mineralisation require drill testing. Additional drilling will also be required at the Intiedougou (A, B, C zones) and Peksou deposit in order to confirm previous drill results and to bring the currently defined gold mineralisation into a JORC compliant resource category.

Orezone also conducted scattered drilling at the Ma and Sebedougou prospects. These two prospects are located within a 3.5km x 400m wide NW-trending +40ppb Au in soil anomaly associated with both NW and NNE-trending shear zones containing pyritic quartz and quartz-feldspar porphyry intrusives within strongly altered basalt units (Fig. 8). Previous drilling returned several significant intercepts including 15m @ 3.3g/t Au from 4m, 10m @ 3.6g/t Au from 9m, 24m @ 2.1g/t Au from surface and 22m @ 1.0g/t Au from 8m. Systematic RC and RAB drilling is required at both these prospects and across the entire, very prospective soil anomaly.

Orezone only drill tested three of the dozen or so gold in soil anomalies that exist within the Golden Valley Permits. Regolith mapping and interpretation work has commenced in order to determine the distribution of residual and transported soil cover and subsequent validity of the Orezone soil geochemistry. Numerous artisanal mining sites are currently active on the Intiedougou and Mougue permits, where preliminary mapping and rock chip sampling has been completed. Best rock chips results include 35.8g/t Au, and 5.6g/t Au from the Nabale Prospect, 20.9g/t Au, 9.0g/t Au, 7.0g/t Au, and 6.3g/t Au from the Nabere Prospect, and 11.3g/t Au, 9.1g/t Au, 6.4g/t Au and 6.1g/t Au from the Gogoba West Prospect (Fig. 9). The Nabere and Gogoba West gold mineralisation requires first pass drill testing.

Boss Resources has secured an RC rig in order to confirm and expand the currently defined gold mineralisation within the Intiedougou permit. The program is due to commence early in December 2011.
