However, as part of this major work programme, SLDChas also located several sites with a high potential of discovery for variousprecious, base and minor metals. The Company is pleased to report an update onits uranium and niobium exploration projects. Uranium Exploration Regional geochemical stream trap site sampling identified a 4,000 square kmarcuate zone of anomalous 5 to 30 parts per million (ppm) uranium resultsassociated with later Liberian granite bodies intruded into the Leonean gneissbasement. The arcuate uranium anomaly is approximately 30 km wide and begins atthe town of Koardu on the Guinea border, running parallel with the border forapproximately 70km in a north-north-westerly direction, before turning 70km inan east-westerly direction towards Kumala, a town located 20km to the south-eastof Tonkolilli. External to this 4,000 square km area, the background values are in the rangefrom 0 to 3ppm uranium. The smallest anomaly covers a 30 square km areaconsisting of a cluster of 5 sample points ranging from 5 to 20ppm uranium. Thetwo most significant anomalies are the 160 square km Lovetta anomaly comprising21 results ranging between 8 and 43ppm and the 240 square km Gertrude anomalythat consists of 18 results ranging between 10 and 30ppm uranium. The Lovetta anomaly centred on the village of Taindu is coincident with a 15 kmlong 4.2 km wide elongate Liberian granite intrusive emplaced into the Leoneanbasement. The actual area of anomalism is 22 km in length and 8km in widthcovering the elongate granite and surrounds. To date, approximately 500 soilsamples out of a 1,000 soil sample program have been collected of which 228 arebeing processed in SLDC Bo Laboratory in preparation for analysis at Ultra TracePty Ltd in Australia. Sampling is carried out on 800m line spacing and 100msample spacing. In conjunction with the soil sampling an orientationScintillometer survey is in progress to determine the optimum spacing. The Gertrude anomaly centred on the village of Weima is more diffuse andassociated with the margin of a Liberian intrusive. Twenty seven orientationstream sediment samples have been collected and dispatched to Ultra Trace. Theresults will determine the sample collection medium for the remaining 150 infillstream sediment samples that will be required in conjunction with orientationScintillometer surveys. The other 8 Uranium anomalies are smaller in area, often more diffuse and lowerin tenor but similarly associated with Liberian granite emplacements and willrequire follow up sampling and investigation. Niobium Exploration Approximately 25 km to the north-west of Farangbaya centred on the village ofSendugu another Liberian granite emplacement returned a Niobium anomaly. Niobiumcommonly occurs with Colombite-Tantalite the source for Tantalum. This 21 kmwide and 23 km long north-easterly trending anomaly drains the north-easternpart of the granite pluton. The anomalous zone covered 15 stream sediments thatare over 0.8 ppm Niobium against a background of less than 0.2 ppm Niobium.Small scale operators are currently mining alluvial Colombite-Tantalite in thevicinity. This anomaly covers an area of 160 square km that requires infillstream sediment sampling and field investigations.
