Ongoing drilling at the Itetemia gold property in the Victoria Lake gold district in Tanzania has confirmed the volcanogenic nature of mineralization.
Tan Range Exploration (TNX-A) reports that five core holes intersected the Golden Horseshoe reef, a quartz-pyrite exhalative horizon, and a new sulphide-bearing gold zone 70 metres to the south. The zones are separated by siliceous rocks and bounded by volcanic tuffs, and their proximal location is considered consistent with a volcanogenic origin.
Gold values ranged from nil to 6.81 grams gold per tonne over 1.81 metres (50.8 to 52.6 metres). The widest gold-bearing interval came from hole 31, which yielded 3.21 grams gold over 9.5 metres (from 111.5 to 121 metres).
Tan Range notes that the new zone was not detected in the
induced-polarization (IP) survey that resulted in the discovery of the Golden Horseshoe reef in 1997, and suggests, therefore, that similar zones might be nearby. In light of this, the company is having its geophysical data reinterpreted by an independent consultant in hopes of pinpointing future drill targets.
The Golden Horseshoe reef has been traced over a length of 360 metres and to a vertical depth of 100 metres; the coincident IP anomaly extends for an additional 1.8 km. The widest interval from previous drilling is 33.3 metres (from 25.3 to 58.6 metres) averaging 2.76 grams gold.
