Arizona: Buckeye

The Arizona project has made significant strides through 2016 and the first quarter of 2017 with the Buckeye mine patents receiving the bulk of the work in these initial stages. The Company assembled an experienced mining team who have dewatered the adit and rehabilitated the underground workings, accessed the vein, and mucked out the workings. The Company has fully equipped an assay facility, a small gravity pilot plant and has poured 500 ounces of dore silver. It has purchased a two boom jumbo to drill the face of the mine; a 2.5 cu.yd. mucking machine to move ore to surface; ventilation equipment; and the necessary ancillary items to commence work underground. The Company is currently building its evaporation ponds, security and shop facilities.

The Buckeye Patent covers less than 1% of Northern Sphere's Arizona land package. NSM's Black Diamond Property, contiguous with the Buckeye Property, has multiple prospects, including historic underground silver mines such as the McMorris-La Plata Mine, Jumbo Mine and Silver Sevens Mine. In addition to the historic underground silver mines, large scale, near surface, silver-gold prospects exist in the vicinity and are part of an ongoing large scale geochemical sampling program which began in June 2017.

On  June 2, 2016 Northern Sphere completed its first pre production processing run of material from Buckeye.  NSM successfully produced 143 ounces of Silver dore and over 200 ounces silver in concentrate, the silver / gold / copper bars were produced by gravity separation. The run of mine     (ROM ) consisted of approximately 800 lbs. of feed to the mill. Internal assays done in its onsite assay facility established the grade to be 500 ounces per ton.

AS of July 2017 NSM 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 is expected to be completed during the month of August.
