| The Stormyra deposit was discovered by Sulfidmalm A/S and Blackstone Ventures Inc. joint venture in 2004. From the web page of Blackstone Ventures Inc.(http://www.blv.ca/s/Espedalen.asp): The Espedalen Ni province covers approximately 55 square kilometres and is centered on a large differentiated mafic intrusion. Numerous small mines, worked in the mid 1800's, and showings occur throughout the property area. Disseminated and massive sulphide type nickel-copper mineralization is typically associated with the peridotite intrusions. Grab samples of high-sulphide mineralization from four of the historical mine dumps average 1.9% Ni and 0.6% Cu. In spite of being extensively mineralized, the area has received only minor amounts of exploration and no modern geophysics. To date, airborne and ground-based UTEM geophysical surveys have identified numerous geophysical conductors. Subsequent drilling of UTEM conductors has returned high grade nickel mineralized zones. The Stormyra target: Drill intercepts of significant nickel mineralization at the Stormyra (P2) target; 14.6m of 1.73% Ni, 0.77% Cu, 0.06% Co and 2.7m of 2.07% Ni, 1.20% Cu, 0.07% Co. January 2009: NI 43-101 classification done by Reddick Consulting Inc.: at a US$100 GMV cut-off, Stormyra contains approximately 1.0 million tonnes of Inferred mineral resources grading 1.09 % Ni, 0.48% Cu and 0.04% Co. Drake refined the Mineral Resources at Stormyra (1.16Mt @ 1% Ni, 0.42% Cu & 0.04% Co) and Dalen (7.8Mt @ 0.28% Ni, 0.12% Cu & 0.02% Co) prospects in accordance with JORC (2012). |
