Drilling identified a steeply-dipping gold stock-work 200 metres wide in the north of Klyuchi West.
Highlights from the drilling include:
- Hole SDH18-39, which intercepted 2.03 grams per tonne (g/t) gold (Au) over 10.15 metres; 5.83 g/t Au over 5.55 metres; and 2.64 g/t Au over 10.55 metres.
- Hole SDH18-40 intercepted 0.82 g/t Au over 46.45 metres; 2.3 g/t Au over 9.4 metres and 1.76 g/t Au over 10.9 metres.
- Hole SDH18-34 intercepted 1.17 g/t Au over 31.75 metres, including 2.06 g/t Au over 9 metres.
- Hole SDH18-35 intercepted 1.27 g/t Au over 58.5 metres, including 2.63 g/t Au over 10.5 metres.
- Hole SDH18-41 intercepted 1.0 g/t Au over 41.1 metres; 1.5 g/t Au over 15.9 metres and 3.33 g/t Au over 9.85 metres.
"Although Orsu identified a gold-mineralized stock-work at Klyuchi West in 2017, its extent remained unknown. New drilling in 2018 intercepted a 200-m-wide envelope with voluminous disseminated porphyry-like gold mineralization, superimposed by a linear 75-m-wide stock-work of north-west-trending gold-quartz veins. The highest gold grades tend to appear near the contact between granite and granodiorite porphyry intrusions,” explained Dr Alexander Yakubchuk, the director of exploration at Orsu.
“The stock-work trends towards the central part of the Kozie prospect, located some 250 m north-west from Klyuchi West. The area in between was never drilled or trenched in the past, and Orsu is currently drill-testing this area," he added.
Dr Sergey Kurzin, the executive chairman of the company, said the drilling results were “great news”.
“It is hoped that results from further drilling will connect this stock-work with the Kozie occurrence, to potentially double the expected size and tonnage of the Klyuchi West zone,” Dr Kurzin said.
“We are nearing completion of the 2018 exploration program having drilled 8 000 out of 10 500 planned metres. I am very happy with what we have seen so far. All three zones that we worked on this year - Zone 23, Adit 5 and Klyuchi West - comfortably met and more often exceeded our expectations by a margin. Orsu is firmly on track to deliver the resource statement in Q4 2018," Kurzin said.
