Northern Sphere Mining Corp. provided an update on it's ongoing diamond drill program at it's patented Buckeye Property, located adjacent to Freeport McMoran-BHP's open pit copper project in Miami, Arizona. The company has completed nine (9) holes, testing the major structure, below the historical underground workings that can play host to high-grade silver mineralization. The drilling intersected the host structure on all 9 holes, all exhibiting pervasive alteration and mineralization. The company has moved forward and is expanding the program. Additional holes will target areas below the surface sampling completed in February 2017 where systematic rock-chip channel samples taken perpendicular to the strike of the mineralized structure, yielded silver grades of 38.2 ounces per tonne (opt) over 0.8 ft, 12.2 opt over 3.0 ft, and 4.0 opt over 5.0 ft. The mineralization is on strike with the historic Buckeye Structure, which had grab samples selectively taken within the mineralized structure (and may not be representative of the entire mineralization), yielding assays of 227.4 opt, 22.7 opt and 88.7 opt. These samples were collected where the central portal re-accessed the historical working at the bottom of the decline. Laboratory analysis for the first (9) nine holes are expected to be completed during the month of August. Northern Sphere is currently reviewing a prospective surficial copper-iron-gold prospect known as the Iron Nugget. The prospect, located on the Black Diamond Claims was mapped and sampled last in 2011 by Trueclaim Resources, when chip samples taken from surficial exposures returned copper values between 2.3% and 7.4% copper.
