White Cliff Minerals Ltd (ASX:WCN) has completed its second diamond drill hole at the emerging Aucu gold deposit in Kyrgyz Republic, central Asia.
The 224 metre deep hole was drilled below surface channel sampling that discovered 2 metres at 9 g/t gold as well as visible gold in quartz.
Four mineralised zones with substantial sulphides have been intersected with the drill core to be sent to the lab later this week for assaying.
Two drill rigs are currently drilling two new holes while assay results from the first hole, which intersected three mineralised zones, are expected within the next two weeks.
The 2016 exploration program is focussed on drilling out the eastern upper gold zone (UGZE) which has an exploration target of 1-2 million tonnes at 15-30 g/t for 500,000 to 1.2 million ounces of gold.
Drill hole details
The 224 metre deep hole encountered four mineralised zones at depths consistent with the high grade zones encountered in the adjacent hole drilled in 2015.
The four intersected mineralised zones were:
- 2.9 metres from 198.1 metres consisting of sheared granodiorite, 25% quartz veining, 45% disseminated pyrite;
- 1.9 metres from 203.0 metres consisting of sheared granodiorite, 5% quartz veining, 40% disseminated pyrite;
- 6.0 metres from 208.0 metres consisting of sheared sandstone, 30% quartz veining, 20% disseminated pyrite; and
- 2.7 metres from 217.0 metres consisting of sheared sandstone, 2% quartz veining, 60% semi-massive pyrite.
The core will be cut and sampled on site and delivered to the laboratory later this week.
Assay results are expected to be available in 4 weeks.
Aucu gold deposit
The 89% owned Aucu gold deposit is located in the Kyrgyz Republic, which is a democratic republic bordering Kazakhstan and western China.
The company announced a maiden inferred resource for the Aucu gold deposit above a cut-off grade of 1 g/t gold of 1.15 million tonnes grading 4.2 g/t gold for 156,000 ounces of contained gold.
In 2015, drilling identified exceptional gold mineralisation east of this resource in the UGZE over a strike length of at least 500 metres.
Results included 8 metres at 55.2 g/t gold and 4 metres at 59.9 g/t gold.
Overall metallurgical recovery of all mineralised zones discovered at Aucu is 99% with gravity recoverable gold averages of 88.6%.
2016 Drill Program
Two rigs are currently drilling the third and fourth holes of a 5,000 metre program.
Drilling is currently targeting the UGZE where the average grade of mineralisation intersected in the 2015 drill program was 45 g/t gold.
Drilling is focused on an 800 metre long section of the UGZE to a maximum vertical depth of 200 metres.
The exploration target for the UGZE in 2016 is 1-2 million tonnes at 15-30 g/t for 500,000 to 1.2 million ounces of gold.
This exploration target is based on the average grade of previous drill intersections completed in the UGZE in 2015.
With drilling and laboratory assaying in progress, news is expected from Aucu regarding:
- Assay results from the first completed diamond hole;
- Assay results from channel sampling completed to date; and
- Preliminary results from two holes currently in progress.
