China Yunnan Copper Australia targets Australian copper, owned by China's largest copper producer
wotnews.com.au
China Yunnan Copper Australia Limited (ASX:CYU) has commenced a reverse circulation (RC) drilling program on untested geochemical, geophysical, geobotanical and geological copper anomalies at its northwest Queensland project areas of Cloncurry North and Mount Isa located in the highly prospective Mount Isa Inlier. China Yunnan Copper is an Australian company formed to explore for and develop minerals in Australia and overseas. Cornerstone investor, Yunnan Copper Industry (Group) Co Ltd, is one of China’s largest copper producers.
CYU is targeting high quality copper, gold and uranium projects with eleven wholly owned Exploration Permits for Minerals (EPM’s) in the Mt Isa Inlier, Ravenswood-Pentland Province and the Clermont Inlier in Queensland. Main Points of drilling program - 1,700 metres reverse circulation drilling program over two prospects on untested geochemical, geophysical and geological copper anomalies within the Cloncurry North and Mount Isa projects. - Two high priority targets (Gem and Mount Colin West).
- Ground magnetic surveys completed focusing on granite - sediment contacts and known magnetic and soil copper anomalies. - Exploration is targeting iron oxide-copper-gold and shear-hosted copper deposits. A 1,700m RC drilling program in 10 holes is being undertaken to test combined geophysical, geochemical, geobotanical and geological targets in two areas, the Gem prospect located in EPM 12205 of the Cloncurry North Project and the Mount Colin West prospect located in EPM 15248 of the Mount Isa Project.
Gem Prospect – Cloncurry Project Situated in the central west of EPM 12205, the Gem Prospect contains numerous old workings that have been sunk on a northwest trending zone of copper mineralisation. Additional prospecting pits have been located to the south of Cattle Creek and to the north of the main line of workings. No modern day exploration is evident within the prospect area.
Mineralisation appears to be confined to structural corridors (shear zones) within the granite country rock. These corridors consist of a series of sub-parallel quartz veins and vary in thickness from less than 1m to more than 10m in width. The overall strike length of these workings is greater than 650 metres. In late 2008 CYU conducted a soil geochemistry survey on a 400m by 700m area on 50m line spacing at 40m sample centres.
Broad areas of spot anomalies were defined and an infill survey on 25m line spacing at 20m sample centres was completed to tighten up the anomalies. The The main soil geochemical anomaly (more than 200ppm copper) trends northwest for over 100m and returned peaked values of 10700ppm copper (1.07% copper) and 2520ppb gold (2.52g/t gold) associated with the old workings. Mount Colin West Prospect – Mount Isa Project Situated to the west of the Exco Resources Mount Colin deposit open cut (Mining Lease 2640), the Mount Colin West prospect lies in the northeast portion of EPM 15248 of the Mount Isa Project.
The Mount Colin deposit currently has a JORC compliant resource (measured, indicated and inferred) of 667,200 tonnes at 3.43% copper. The Mount Colin deposit is a mineralised shear zone ranging from 5m to more 20m that has reported yielded 122 tons of copper with an average grade of 9.4% Cu from historic shafts and shallow pits. The mineralised shear zone strikes approximately east - west with an overall steep northerly dip of about 75º.
In early 2009 CYU undertook a ground magnetic survey and surface geochemistry soil sampling program over the area to the west of the Mt Colin mining lease. Soil sampling results are still pending. The ground magnetic survey delineated a strong magnetic anomaly that is trending with the same orientation of the known workings with an associated magnetic low.
This trend is postulated as the trend of mineralisation. A total of five RC drill holes are being drilled to test a possible strike extension of the Mount Colin deposit.. Fri May 2009 01:05 (1 day, 17 hours ago) |
