Tsodilo Resources Limited released an exploration update for its work in Botswana and Namibia in early January. The company's Botswana licenses are near to two major unexplained surface concentrations of diamonds and G10 garnets across the border in Namibia, one near the village of Tsumkwe and another in the area known as Omatako. The company reports that the characteristics of these kimberlite pathfinder mineral anomalies indicate that they are secondary concentrations derived from respective primary high-grade kimberlite sources located elsewhere. The geomorphological model envisages that the Tsumkwe and Omatako pathfinder anomalies were formed by ancient rivers transporting diamonds and garnets derived from kimberlites located in the Company's license blocks. Prior to the deposition of the superficial Kalahari sand that covers much of Ngamiland, this area formed a topographic high. Rivers rising off this high ground flowed westward into a major inland sea located in the north of present-day Namibia. The company's diamond targets cover former headwaters of this ancient river system and lie within the southern margin of the Congo craton.
Tsodilo Resources has offices in Toronto, Canada and Gaborone and Maun, Botswana. You can read the full report on the company's website.
