Copperstone Announces Assay Results of VDD0201 and VDD0202 Drill Holes

Copperstone takes pleasure in announcing that the test results of VDD0201 and VDD0202 assays have been obtained from ALS laboratories and compiled by Copperstone, and confirmed by the Qualified Person (QP) of the company.

Highlights

  • Phase 1 shallow drilling on A zone has been completed successfully.
  • VDD0201, drilled beyond the mineral resource boundary, intersected considerable copper mineralization in the A main zone and the footwall lode, respectively, 15 m at 0.73% Cu from a 40 m downhole depth and 6 m at 1.45% Cu from a 103 m downhole depth (65 m vertically below surface).
  • VDD0202 intersected 18 m at 0.54% Cu from a 27 m downhole depth, including 3 m at 1.85% Cu. This intercept fits extremely well with the A zone resources wireframe.
  • Assaying at VDD0203 and VDD0204 are pending.
  • D zone deep exploration commenced with an intended depth of 1000 m for VDD0205.

The initial drill campaign of Copperstone on the Viscaria property started on September 17th, 2019. It confirmed the veracity of the historic shallow copper deposit and intersected important copper mineralization at the footwall lode. Drilling of VDD0201 lasted for four days and ceased as scheduled at 150 m, whereas drilling of VDD0202 lasted for three days and ceased as scheduled at 70 m.

VDD0201 Details

VDD0201 has been drilled from the hanging wall to the footwall of the A zone mineralization, beyond the boundary of the present Mineral Resource, i.e. virtually adding mineralized mass. Copperstone intersected two important shallow mineralizations, which were not included in the resource wireframe in the past:

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

VDD0202 Details

VDD0202 has been drilled to analyze the veracity of the historic drill assay. The hole intersected 18 m at 0.54% Cu from a 27 m downhole depth, including 3 m at 1.85% Cu from a 41 m downhole depth. This intercept fits extremely well with the A zone mineralization wireframe. Here, Copperstone has proof of the footwall lode by D-3167 that intersected 8 m at 0.4% Cu from an 87 m downhole depth.

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.

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,” commented CEO Michael Mattsson.

We are already planning for the next shallow drill campaign. This while awaiting the assays from VDD0203 and VDD0204. Meanwhile, the D-zone drillings could be approaching its exploration target.
