TORONTO, ONTARIO - December 8, 2004
- Tsodilo Resources Limited ("Tsodilo") (TSX Venture Exchange: TSD) is pleased to announce the discovery of a new kimberlite on its Newdico (Pty) Limited license block in Botswana.
Drill target A16 is a coincident magnetic and gravity anomaly with an indicated diameter of approximately 800 - 1,000 meters. The magnetic anomaly is dipolar and roughly circular, indicative of a pipe-like intrusive body. (See, geophysical gravity and magnetic images on the Company's website under Images - Geophysical
) The target was tested with a vertical reverse circulation drill hole. After drilling through loose sand to 25 meter depth (Kalahari Formation), a sequence of limestone breccias mixed with vein quartz and biotite rich shales was intersected to the end of the hole depth of 143 meters. Although no kimberlite was intersected, the breccias have been identified in the field as altered kimberlite crater material similar to that intercepted in kimberlite intrusives A12 and A37 previously discovered by the Company.
Drilling commenced on November 24th, 2004 and ceased on November 28th. Due to technical problems of drilling with a high groundwater inflow, the drill hole was stopped at 143m depth still in crater facies The interception of kimberlitic crater material at this depth indicates that the pipe is well preserved.
Target A16 is located approximately 20km east of the Namibia / Botswana border in the Company's Newdico license block. The kimberlite lies within the Nxau Nxau kimberlite field where 23 kimberlites have been identified to date. Target A16 lies approximately 1.5 km from a kimberlite intrusive (anomaly 40/97/07, drillhole THC 16) discovered by the Ashton / Reunion joint venture in February of 1998. This kimberlite tested positive for micro-diamonds. Previous geochemical loam sampling work over A16 resulted in the collection of numerous picro-ilmenites.
Drill cuttings will be sent to Mineral-Logic in Cape Town, South Africa, for integrated petrographic and indicator-mineral analysis and if warranted to the Saskatchewan Research Council for micro-diamond analysis and interpretation. The results will be released on completion of the processing.
On October 25, 2004 the Company announced the discovery of this kimberlite intrusive. Photos of kimberlite indicator minerals recovered as a result of the drill program have been posted to the Company's website (See, Image Gallery - A15 - Kimberlite Indicator Minerals (KIMs)
). These and other specimens recovered have been submitted for electron microprobe analysis. The results will be released on completion of the processing.
Border Gravity Survey and Drill Program
As announced on October 13, 2004, the Consultant Geophysicist commissioned to perform the gravity survey along the border completed his initial line of survey along a 30km portion of the border. This line straddles a prominent linear satellite image feature (See, under Images on the Company website the area indicated on the satellite imagery as Border gravity points
). The gravity survey shows that this image feature is coincident with a major gravity low (between stations 200 and 460m), which the geophysical consultant interprets to reflect a major pre-Kalahari valley. A further gravity low (between stations 0 - 100) has been interpreted to reflect a second channel to the south. On November 3, 2004, the company began a series of shallow drill holes along this border section. In total, 19 holes were drilled for a total of 405 meters. Samples from these drill holes were collected and the Company will confer with its Consultant to interpret and analyze these results.
Drilling on target 2021 B4 began on November 9th and due to the technical and equipment deficiencies of the drilling contractor, the first hole on this target collapsed at 96 meters. The Company decided to abandon the first hole and started a second hole on the target. The second hole began on November 13th using a combination of DTH, RC, and rotary mud drilling to reach the interpreted target depth of 150m. The thick sequence of Kalahari sediments, to 158m was followed by a magnetite quartzite. The hole was terminated at a depth of 175metres.
Previous geochemical loam sampling work over 2021 B4 resulted in the collection of a single diamond inclusion eclogitic garnet. Diamond inclusion eclogitic garnets are Ti-poor, but have relatively high Na2O (>0.7% Na2O). The garnet recovered from the northern portion of the Gcwihaba ground is one of the latter variety, i.e., matches eclogitic diamond inclusion compositions.
The Company intends to test the other targets in the northern Gcwihaba ground for which ground gravity and magnetic surveys have been performed when the drilling program resumes after the worst of the rainy season early in 2005.
Tsodilo Resources is an international diamond exploration company engaged in the search for economic kimberlites at its Newdico and Gcwihaba projects in northwest Botswana. The Republic of Botswana is the largest producer of diamonds, by value, in the world. Tsodilo has a 75% stake in Newdico while Trans Hex Group, a South African diamond mining and marketing company, holds the remaining 25%. The southern Gcwihaba Project area is 100% held by Tsodilo subsidiary Gcwihaba Resources (Pty) Limited. Tsodilo manages the exploration of both license areas. The design and conduct of the Company's exploration program is the responsibility of Peter Walker, a professional geologist registered with the South African Council for Natural Scientific Professions.
