Overview
The Nassile project lies 35 kilometres south of the Samira Hill gold mine and 200 kilometres southeast of IAMGold's Essakane Project, in the Sirba greenstone belt.
Cassidy Gold Corp. and Island Arc Exploration Corp. have entered into a mining option agreement dated August 31, 2010 with Middle Island Resources (MIR) Pty Ltd. of West Perth, Western Australia pursuant to which Cassidy and Island Arc have granted MIR an option to acquire up to a 70% interest in the Nassile project located in Niger.
Summary
The Nassile permit covers 576.7 square kilometres approximately 100 kilometres southwest of Niamey, the capital of Niger. Based on fieldwork completed in 2008 and 2009, Island Arc geologists have identified significant gold mineralization along 20 kilometres of a large regional structure, the northeast-trending Tampena shear zone.
Songonduari Prospect
The Songonduari prospect was subject to a recent gold rush of up to 10,000 local artisanal miners; coarse gold was recovered from hard lateritic cover at surface, and from smoky grey, quartz veining at depths of up to 15 metres. Eleven of 60 grab samples returned assays greater than one gram per tonne Au, including 13.1 g/t and 15.5 g/t Au from quartz veins in graphitic sedimentary rocks near the southern limit of the trend. A sample from a sulphide-rich quartz vein, approximately 750 metres to the east, assayed 8.28 g/t Au.
Forbemi
Located two kilometres north of Songonduari, Forbemi is marked by prominent northeast-trending chargeability highs covered by hard laterite that may mask potential mineralization at depth. Significantly, the Forbemi area hosts at least two northwest-towest- trending quartz-sulphide veins. The southern vein is exposed in extensive artisanal workings over a distance of almost 200 metres. Two grab samples from the workings returned assays of 9.20 g/t Au and 6.77 g/t Au.
Bamperi South
The Bamperi prospect covers an extensive chargeability high in the central part of Tampena, Much of the area is covered by alluvial laterite but one trench (No. 17) excavated during the 2008 program intersected 7.55 g/t Au over three metres at the south end of the anomaly. A number of north-south, east-west, and northeast-trending veins have been mapped and sampled. Grab samples from one such vein over one kilometre northeast of Trench 17 returned assays of 35.7 g/t Au, 25.1 g/t Au, and 21.8 g/t Au. Sulphides including galena, pyrite, chalcopyrite and bornite appear related to high gold values in quartz veining. Another grab sample 500 metres farther northeast assayed 132 g/t Au.
Bamperi North
Bamperi North, is characterized by several large northeast-trending quartz veins. The largest mapped vein extends over a distance of 1.5 kilometres with high-grade assays from grab samples reported over 600 metres of that distance. There are significant artisanal diggings along sections of the vein. Grab sampling from the central portion of the largest vein returned several very high-grade assays, including 109 g/t and 105 g/t Au, associated with galena. Grab samples 400 metres to the northeast returned assays of 58.2 g/t and 30.0 g/t Au, with seven more grading greater than 10 g/t Au. In all, 23 of 120 grab samples assayed greater than one gram per tonne Au.
Koutougou
Veins mapped at Bamperi project onto the Koutougou area adjoining to the northeast. Grab samples collected from quartz veins at Koutougou returned assays from <0.01 g/t Au to 11.8 g/t Au, but to date work in the Koutougou area has been limited to prospecting. Soil and/or termite mound geochemistry will cover projected mineralized trends followed by RAB and RC drilling.
Tirboye
Regolith mapping at Tirboye, 15 kilometres northeast of Bamperi, has identified several prospective quartz structures in highly sheared metavolcanic and metasedimentary rocks. These vein structures trend north-easterly and strongly resemble the veins mapped at Bamperi North. Grades from 28 grab samples collected from these quartz vein structures at Tirboye ranged from <0.01 g/t to 20.8 g/t Au with 12 samples returning values >1.0 g/t Au.
