Copperstone Resources AB ("Copperstone" or "the Company") is pleased to present an update on the drilling programme at Granliden Hill and to provide information on the current geological interpretation relative to geophysics. Note that assay results from the fourth hole are still pending. (See attached interim technical report).


  • Mineralisation consisting of interspersed chalcopyrite veins has been intercepted in drillhole COS18359 over 81m from 745m to 826m. This mineralisation 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 drillhole COS18356 and from 155.8 to 618.9m in drillhole COS18357 as previously announced. This helps substantiate the porphyry style of mineralisation proposed for the genesis of the Cu sulphides historically drill tested on the project.
  • Geochemistry commensurate with Adakite in drillhole COS18358 provides further validation for porphyry style mineralisation.

"Our drilling work at Granliden Hill is confirming our geological interpretation of the geophysical targets and is beginning to show that copper mineralisation is linked to large scale intrusive features. We are excited to have drilled extensive mineralisation deep under Granliden Hill and we are now awaiting the assay results for this intercept. Our porphyry-style model appears to hold credibility, and we are continuing to build the first deep east-west geological sections across the target area.

The application of deep drill holes well below the shallow historical datasets is proving to be a key to unlocking the scale of the intrusive complex and its related mineralisation." comments Chris McKnight CEO of Copperstone.
