Copperstone Resources AB Pressmeddelande COPPERSTONE RESOURCES TOP HAMMER DRILLING AT GRANLIDEN IS COMMENCED AND SECOND DEEP HOLE ON-GOING AT SVARTLIDEN-EVA Copperstone Resources AB (below ”Copperstone” or ”the Company”) commences top hammer drilling at the northern subproject, Granliden within the Copperstone project. The Company initiates a parallel campaign using top hammer drilling on the northern sub-project Granliden, in order to map the shallow part of the bedrock down to a maximum of 25 meters and thus create a more extensive understanding if Granliden (as Svartliden-Eva) is an altered system of hydrothermal origin and, if so, this area also potentially is a mineralization of copper-gold porphyry-type. Results from the top hammer drilling will, combined with information from existing diamond core drilling on the sub-project, make an excellent foundation for planning further core drilling in the area. “The work on the Copperstone project continues in an extensive scale. In the southern sub project, Svartliden-Eva, the second of three planned deep drill holes is in progress as planned and presented in the technical report published in the end of January. Within short we await results from the assay results from core of the first drill hole, which was a great success and was terminated at approx. 1166 meter, which is the capacity of the equipment. Accordingly, we now commence mapping of the bedrock in the northern part of the Copperstone project where the Company, in addition to the mineral resource at surface, in its significant database has mapped drill core with sections of significant mineralisation at 300 to 400 meters depth. The aim of the drilling is to create a better foundation for further core drilling to develop this part of the potentially extensive Copperstone area” comments Copperstone CEO Per Storm.
