A further 11 drill holes from the NANR campaign and the earlier Copperstone campaign 2015 have also been sampled.
Copperstone Resources (NASDAQ:COPP_B) has announced significant copper assay results from drill hole COS18364 in the Granliden Hill area.
As highlighted in the press release:
103m of semi-continuous chalcopyrite mineralization intercepted from 315-418m returning 0.42 percent copper and 3.24 grams per tonne (g/t) silver and containing an 11m zone from 343-354m returning 2.62 percent copper, 17.5 g/t silver and 0.2 g/t gold.
The company said at the moment laboratory testing is still ongoing for drill holes COS18360, COS18362 and COS18363. A further 11 drill holes from the NANR campaign (2004-2007) and the earlier Copperstone campaign 2015 have also been sampled. The main objective of the latter is to close the gaps within the sample string so that composite grades can be determined.
