Copperstone Resources Releases Interim Technical Report on Granliden Hill

- May 17th, 2018

Copperstone Resources has released an update on the drilling programme at Granliden Hill in Sweden to provide information on the current geological interpretation relative to geophysics.

Copperstone Resources (NASDAQ:COPP B) has released an update on the drilling programme at its Granliden Hill project in northern Sweden to provide information on the current geological interpretation relative to geophysics.

As highlighted in the press release:

  • Mineralization consisting of interspersed chalcopyrite veins has been intercepted in drill hole COS18359 over 81m from 745m to 826m. This mineralization is associated with a vertical resistive Natural Source Audio-frequency magnetotelluric (NSAMT) feature which has considerable strike and depth extent and is being drill- tested for the first time.
  • Potassic alteration is a characteristic style of alteration in porphyry style deposits and was intercepted over several hundred metres (from 110.7m to 361.4m) in drill hole COS18356 and from 155.8 to 618.9m in drillhole COS18357 as previously announced. This helps substantiate the porphyry style of mineralization proposed for the genesis of the copper sulfides historically drill tested on the project.
  • Geochemistry commensurate with adakite in drill hole COS18358 provides further validation for porphyry style mineralization.
