Viscaria Drillings – VDD0201 returns 15m @ 0.73% Cu and 6m @ 1.45% Cu outside the Mineral Resource Boundary

Kiruna October 18, 2019

Copperstone is pleased to announce that the assay results of VDD0201 and VDD0202 have been received from ALS laboratories and compiled by Copperstone, verified by the QP.


  • The phase 1 on A zone shallow drilling has been successfully completed.
  • VDD0201, drilled outside of the mineral resource boundary, intersected significant copper mineralisation in the A main zone and the footwall lode, respectively 15m@0.73%Cu  from 40m and 6m@1.45%Cu from 103m downhole depth (65m vertically below surface).
  • VDD0202 intersected 18m@0.54%Cu from 27m downhole depth, including 3m at 1.85% Cu. This intercept fits very well with the A zone resources wireframe.
  • VDD0203 and VDD0204 assaying pending.
  • D zone deep exploration started with VDD0205 planned depth 1,000m.

Copperstone’s first drill campaign on the Viscaria property commenced on September 17, 2019, and confirmed the veracity of the historic shallow copper deposit and intersected significant copper mineralisation at the footwall lode. VDD0201 was drilled for four days and stopped as planned at 150m. VDD0202 was drilled for three days and stopped as planned at 70m.

VDD0201 details:

VDD0201 is drilled from the hanging wall to the footwall of the A zone mineralisation, outside the boundary of the current Mineral Resource, i e potentially adding mineralised tonnage. Copperstone intersected two significant shallow mineralizations, previously not included in the resource wireframe:

  • The A main zone: Copperstone intersected a broad mineralisation of  39m@0.43%Cu from 40m downhole, included two continuous mineralisation zones:
    • The first zone   15m@0.73%Cu from 41m. This zone is likely the  same mineralisation lode as was historically intersected by drill holes D-8149 ad D-8507, respectively 15m@1.2%Cu from 34m downhole and 6m@1.8%Cu from 46m downhole.
    • The second zone intersected 10m@0.46%Cu from 69m downhole.
  • The A footwall lode: Intersected 6m@1.45%Cu from 103m downhole depth.

VDD0202 details:

      ·VDD0202 is drilled to test the veracity of the historic drill assay. The hole intersected 18m@0.54%Cu from 27m, including 3m at 1.85% Cu from 41m downhole.This intercept fit very well with the A zone mineralisation wireframe. In this section, Copperstone has evidence of the  footwall lode by D-3167 which intersected 8m@0.4%Cu from 87m.

“The success of this first drilling campaign at A zone give us high confidence to plan a strategic low risk activity. We will immediately move forward to the next step by planning shallow drilling, to follow up the significant hanging wall and footwall lodes. This data will be valuable to reinterpret and re estimate the A zone shallow resources, prior to the feasibility studies. We are confident that the resources will significantly improve.”, comments Maurice Zongo, Project Geologist.

“The first lab assay results from A zone drilling are very encouraging.  It confirms both that the historical drilling assay data is reliable, and that the shallow mineralisation at A zone does indeed exist and can be increased. We are already planning for the next shallow drill campaign. This while the awaiting the assays from VDD0203 and VDD0204. Meanwhile, the D-zone drillings could be approaching its exploration target.”, comments CEO Michael Mattsson.
