Introduction
The Wa Project consists of one granted Reconnaissance Licence situated in NW Ghana near the border with Burkina Faso. Castle has an option to acquire a 100% interest in the project from Newmont Ghana Gold Limited. The 0.3Moz Julie gold deposit is located within an excised portion of the Wa Project. Azumah Resources 0.5Moz Kunche gold deposit is located 50km north.
The 8,200 km² Wa project was acquired from Newmont Ghana Gold Limited (NGGL) in November 2007. An extensive sampling and mapping program was undertaken in February and March 2008 with 2,269 samples collected from a variety of areas.
Castle has identified a large number of gold in soil anomalies including a strongly anomalous 2,000m long x 1000m wide area west of Crew Gold's 300,000 ounce Julie gold deposit.
This area has reported values up to 3,096 ppb gold (3.09g/t gold) and is hosted by sedimentary rocks flanked by granites to the north and south. In 2008 rock chip sampling defined a high-grade zone of quartz vein hosted gold mineralisation over 500m long.
Nine rock chip samples collected from quartz vein material exposed in shallow workings along a 500m zone averaged 22.2g/t gold. This mineralised area is hosted within a discrete granite body bounded by sediments to the north and south.
The zone of quartz veining is interpreted as being along the same structure as the neighbouring Julie gold deposit (5km to the east). The Julie deposit is an east-west trending zone with shear-hosted gold mineralisation occurring along a granite/basalt contact. Crew Gold (CRU:TSX) has reported an unclassified (inferred) resource of approximately 3.3 million tonnes for the top 30m of the Julie target, containing about 300,000 oz gold.
Seventy eight rock chip samples were collected as part of a program of mapping and field checking of the significant gold in soil anomaly returned from Castle's earlier program of geochemical sampling. Further mapping and sampling is proposed, including trenching of this zone.
