Welcome To CuDECO

CuDeco Ltd is an Australian Top 300 listed ASX Company.  The company has one project the "Rocklands Group Copper Project" that is located only 15klms from the large regional township of Cloncurry in North West Queensland Australia.  The Rocklands Project is located in the biggest known copper belt of Australia and is host to the giant Mt Isa Copper Mine and the Ernest Henry Copper Mine.

 

As at the end of November 2008 the company has completed approximately 160,000 metres of RC and diamond core drilling in over 1,000 holes and over 2,000 bedrock drill holes. The Rocklands Group Copper Project is one of the largest single exploration programs in Australia and would be in the top three exploration programs ever in Australia for the past decades to have completed such a large drilling and exploration program in such a short period. 


The company has achieved this milestone within only 2.8 years of drilling and exploration with an expenditure likely to exceed $50m by the time the drilling has been completed.  The drilling and exploration commenced on a prospect known as "Double Oxide" which was historically mined as a high grade native copper underground mine that produced some 390 tonnes of copper metal from 890 tonnes of ore. The average grade of the ore was 44% Cu.  

 

The drilling of Double Oxide culminated in a strike length of 800m being achieved  and recently this strike length has been extended to 1800m with additional drilling.  During the exploration phase a new area of mineralisation was discovered and named Las Minerale (lost mineral). In 2006 the company announced a JORC Resource statement of 59mt @ 2%Cu equivalent in the inferred category for Las Minerale. This was later reduced to 25mt @ 2% Cu equivalent at the request of the regulator.  The regulator believed at the time  there may not have been enough drilling at that time to assume the strike of the mineralisation exceeded 600m and the depth exceeded 375m. 

 

The drilling to date has now identified a 1900m strike of the Las Minerale prospect and has interesected mineralisation to a depth below 375m.  In addition the company has been drilling several other zones of mineralisation within the Project area and in the immediate proximity of Las Minerale.  These new zones include several new sub-parallel zones of mineralisation with a 500m wide shear zone originally discovered by Rio Tinto in 1992.

 

Rio described the shear zone as a "potentially significant resource of low grade copper".  Drilling by CuDeco in the 500m wide shear zone has identified a 700m long strike of a multiple of sub parallel zones within the 700mx500m area proving up the Rio theory.  The drilling has been a great success and approx 180 more holes are planned to complete the drilling for a resource statement within this area known as Rocklands Central which incorporates the Le Meridian Prospect.  All of the zones of mineralisation in this shear, appear to strike parallel with Las Minerale.  The company’s geological team has just completed a series of "fence holes" (a line of holes drilled along a grid line at 100m intervals) 1300m to the west of the most western end of the Rocklands Central prospect to test for any possible extensions to the 700m strike length already defined.  The drilling has identified visual sulphides in a number of the holes at varying widths adding to the potential stirke of up to 2,000m (2klms) strike length of the Rocklands Central prospect.   The total length of the strike lengths discovered to date have an aggregate strike length of over 10 klms with numerous other areas indentified by drilling as hosts for further mineralisation.

 

Apart from the giant Las Minerale prospect drilling has also identified the potential for a parallel zone to Las Minerale located approx 150m to the north of Las Minerale ( Las Minerale strikes east/west). The new zone was discovered by SAM survey (Sub Audio Magnetics) geopgysical survey.   To date all holes have intersected high grade Cu mineralisation in siltstone/sandstone which is evident on the North side of Las Minerale and believed to have been affected by the same event that led to Las Minerale being formed.  The southern side of Las Minerale is predominently dolerite and the north side siltstone/sandstone and the potential for the site is considered enormous especially in areas of massive siltstone/sandstone units which are also evident in the Rocklands Central incorporating Le Meridian.  Metallurgical testwork carried out has shown astounding results with a 98.8% recovery on the sulphides at 140 microns and 96%  recovery on the native copper zones which carry the high grade coarse copper within the supergene zones.  Sulphides have been identified at Las Minerale in places on 7m below the surface and grading up to 44% Cu within the chalcopyrite/chalcocite zone.  

 

Las Minerale Central is one of the richest deposits of copper in the world to a depth from surface to 150m within the supergene zone over a central bonanza zone of over 800 metres.  In 2006 I, as the Chaiman of CuDeco, reported that the Rocklands Group Copper Project was one of the richest copper mines in the world and declared Rocklands would be a "World Class Copper  Cobalt Deposit."   I say it again this time with more confidence and conviction.
