October 10, 2008 Africa West Minerals Corp. is pleased to announce that a 2000m Air Core (AC) and Reverse Circulation (RC) drilling program has commenced on the Nyakagwe Gold Project in Tanzania. The program will drill beneath surface gold in soil anomaly trends and trench anomalies outlined from recently completed exploration programs. The Nyakagwe Gold Project is located 6km north west of Barrick’s 10.2m ounce Bulyankhulu Gold Mine. Africa West Minerals, through their wholly owned subsidiary Gold Rim Exploration Inc. is earning 100% of the Nyakagwe project by bringing the property to the Mining Licence category.
Anomalous gold in soil trends coincide with east – west and northwest – southeast trending quartz reefs that have been exposed and exploited by local artisanal miners. Gold in soil anomalies have ranged from 0.08 gAu/t to 0.84 gAu/t. The mineralized trends persist from 180 metres in length to over 800 metres in length. Subsequent trenching on two of the trends has indicated subsurface anomalies from 0.21 gAu/t over 9.0 metres to 0.98 gAu/t over 1.0 metre. Both the trench sampling and the soil sampling were assayed using 500g cyanide bottle roll leaching for 24 hours. This method was employed in order to ensure that any coarse gold in the sample would be dissolved and analyzed. All assays were performed at the SGS laboratory in Mwanza, Tanzania. A regiment of 10% quality control samples as standards and duplicates were used and analyzed.
“We are quite happy to see that the anomalous trends outlined by the surface geochemical sampling are confirmed with subsurface trench results.” comments Jeffrey Ackert, VP Exploration for Africa West. “It seems that the mineralization seen in the local miners’ pits continues along strike and beyond the workings.” The AC and RC program has been targeted to drill beneath the stronger gold anomalies and along strike of several of the persistent gold bearing quartz reefs. The program is expected to be completed by the end of October with results available approximately one month later.
In Kenya, the Ngira-Migori Gold Project is undergoing a first phase regional surface geochemical sampling program. The Ngira-Migori property is located in the southern part of Kenya, within the Migori Archean greenstone belt, and adjacent to the past producing gold and copper McCalder Mine. Mineralization in this area is characterized by gold in quartz reefs as well as gold associated with massive to disseminated sulphides. Surface grab sampling at two of the mineralized reefs returned from 30ppb to 16.7 gAu/t.
Also in Kenya, the Rosterman Gold Project, is undergoing a compilation of available historic data in order to produce a three dimensional geological model. Located near the town of Kakamega in the Western Province, it is the site of the past producing Rosterman Gold Mine. The mine was worked to a depth of 2000 feet between 1935 and 1952 and produced over 250,000 ounces of gold at an average grade of 13.6 gAu/t. Gold mineralization at the Rosterman Mine is typically associated with stacked sigmoidal quartz reefs hosted within and adjacent to a diorite.
