Copperstone Resources AB (“Copperstone” or “the Company”) is pleased to announce favourable results for an extensive geophysical survey recently carried out on the porphyry copper exploration target project in Norrbotten County, northern Sweden. Fieldwork commenced on the 21st September 2017 and has included both a ground magnetic survey and a Natural-source Audio-frequency Magnetotellurics (NSAMT) survey. The objective of this integrated study was to utilize the two geophysical survey techniques to aid in the identification, mapping and interpretation of geology, alteration zonation vector patterns of the proposed porphyry copper model, and to provide targets locations for further core drilling.

In general, the application of combined geophysical surveys has enabled the alteration styles as seen from a large drill dataset to be resolved into halo vectors that indicate a likely source of the system (Target A).  The genetic model for a porphyry copper mineralisation system present at the property has been significantly improved, and now deep core drilling is required to test out this model.

We are very pleased that the 3D modelling of the NSAMT and magnetic surveys has helped to identify the key zonation patterns of our exciting porphyry copper target. During these past months our understanding of the local geology and mineralisation potential has increased significantly. Finding the advanced argillic alteration zone to the east and the deeper magnetic body to the west has increased our belief that the heart of the system remains blind, starting somewhere around 250-300m under the Granliden Hill area. No drill holes have ever penetrated deep into this target area, so drill testing out Target A is now a high priority” comments Chris McKnight, CEO for Copperstone.

The detailed report is attached.
