Northern Sphere Assays 344 g/t Silver Plus Elevated Copper, Nickel, Cobalt and Zinc at Arizona Property

Northern Sphere Mining Corp. (CSE:NSM,OTCQB:NSMCF) released an update on a geochemical survey being conducted at its Black Diamond property, and provided details on recent diamond drilling completed at its patented Buckeye project.

As quoted in the press release:

In efforts to unlock the potential of its Black Diamond Property, which borders the Porphyry Copper Mining District in Miami, Arizona, Northern Sphere has undertaken an intensive Geochemical Soil Survey over its 3,800-acre property culminating with a 35 Element Aqua Regia ICP-AES analysis.

In addition to using geochemical surveys and geologic, geophysical and outcrop sampling data, Northern Sphere is now employing “cutting-edge” Exploration Targeting Technologies to better and more precisely identify drilling targets. Such technologies use Hyperspectral Satellite Imaging in conjunction with ground geochemical data to re-compute existing geophysical survey data to depict more precise 3D signal locations.

Preliminary results from the first 250 geochemical samples analyzed are extremely encouraging. The strategic soil survey, which began near the historic McMorris and La Plata Silver Mines, demonstrated anomalous copper, zinc, and nickel values along with significantly anomalous (up to 344 g/t) silver values (see Figures 4 & 5). More than one third of the first 250 samples taken had silver values greater than 1 g/t (see Figure 3). Ten percent of the 250 samples yielded silver values greater than 10 g/t. A second set of 224 geochemical samples has been collected and shipped to ALS Laboratories for analysis.

The press release also states:

Over the summer, Northern Sphere drilled 14 surface diamond drill holes on its patented Buckeye Project. The drilling targeted structures similar to those which apparently hosted sufficient quantities of silver to warrant extraction from the historic Buckeye Mine.

The drilling was successful in identifying anomalous silver values below several documented highgrade surface and underground showings. The drilling yielded anomalous silver below both the “Square Nail” shaft, and the former Buckeye Mine.

Thirteen of the fourteen holes drilled intercepted the perceived host structure up to 250 metres below the underground workings for a strike length of 400 metres. The width of the structure, and its corresponding alteration, varied between two and six metres. Of the14 holes drilled, 10 of such holes contained intercepts considered to be anomalous. The intercepts contained elevated silver and copper levels varying from 3 g/t to 179 g/t silver and upwards of 4,600 ppm copper. Table 1 depicts most of the noteworthy intercepts.

Combined with surface and underground samples, the diamond drilling has assisted in identifying four areas hosting anomalous to high grade silver (see Figure 5). The drilling results are encouraging and will assist with future drill targeting. Underground rehabilitation could provide better strategic diamond drilling platforms and would allow for the re-accessing of historic mineralized development.
