Ivanhoe's current drill program is focused at the Gold Hill Prospect, where previous drilling intersected two pipe-like quartz vein stockwork zones that host high-grade copper-gold porphyry mineralization. These zones, approximately 100 metres apart, have been designated the Southern Stockwork and Northern Stockwork.
The Southern Stockwork is 20 to 70 metres wide, 450 metres long and at least 300 metres deep, with grades ranging from 0.6 g/t to greater than 5.0 g/t gold and 0.3% to 1.0% copper. The Northen Stockwork is 250 metres long, 150 metres wide and at least 350 metres deep. Grades of 0.3 g/t to 0.5 g/t gold and 0.2% to 0.6% copper are typical, although there are several 10 to 40 metre wide pockets of stronger mineralization with grades of 0.5 g/t to 3.0 g/t gold and 0.5% to 1.0% copper.
