$NSM.ca Arizona Soil Geochemical Sampling Program Returns Elevated Copper-Molybdenum Values

Posted by Er at 1:14 PM on Tuesday, December 12th, 2017

 

    • Black Diamond Property borders Freeport McMoRan’s open pit operations.
    • Intensive Geochemical Survey recovered systematic soil samples on a 50-metre spaced grid
    • Significant anomalous Copper, Zinc and Silver values approach grades at which some deposits are mined
    • Elevated Copper in association with elevated Molybdenum levels, two metals found in association with porphyry copper environments.

Northern Sphere Mining Corp. (CSE: NSM) (OTCQB: NSMCF) (“Northern Sphere” or the “Company”) ‎is pleased to provide an update on its Geochemical Survey being conducted on its Black Diamond Property which borders the Porphyry Copper Mining District in Miami, Arizona.

Figure 1: Miami-Globe, Arizona — NSM’s Black Diamond Claims

Northern Sphere has undertaken an intensive Geochemical Survey over its 3,800-acre Black Diamond Property, located 12 km (8 miles) north-east of Freeport McMoRan’s Open Pit Copper Operations. The Geochemical Survey recovered systematic soil samples on a 50-metre spaced grid. Each sample was submitted to ALS Laboratories for a 51 Element Aqua-Regia digestion and ICP-MS finish.

The survey currently comprises of more than 600 samples from three prospective areas encompassing approximately 370 acres: (i) the Richmond Basin and site of historic underground silver mines, (ii) Buckeye South and (iii) Black Copper where previous outcrop sampling (outcrop samples were grab samples selectively taken within the mineralized structure and therefore are not representative of the entire mineralization) yielded copper values up to 7% (see Trueclaim Exploration Inc. press release of September 29, 2011).

Initial results from the first 250 geochemical samples taken in the Richmond Basin area delineated areas of anomalous (as defined by the values of the sample population greater than the 90th percentile) copper with some significantly anomalous results (exceeding the 98th percentile) as 1,040 parts per million (ppm), 522 ppm, and 340 ppm. Areas defined by anomalous silver were also noted with values reported as high as 344 grams per tonne (g/t) (see the Company’s prior press release of November 11, 2017).

Significantly anomalous copper, zinc and silver values approaching grades at which some deposits are mined is very encouraging. Previous exploration undertaken on the property limits the Company’s ability to gauge the background values for potential economic minerals and their relative proximity to the source bedrock.

Interpreting anomalous trends will be aided by exploration techniques and services which combine Hyper-Spectral Imaging, Geophysical Survey re-inversion, Digital Geologic Modelling, Artificial Intelligence which utilizes machine learning and mineral related algorithms to optimize mineral targeting.

A second soil survey area consisting of 224 samples collected from the Buckeye South area returned exceptional results defining areas with both anomalous copper (values greater than 123 ppm) and zinc (with value highs of 7,660 ppm, 4,820 ppm, and 4,770 ppm). Figure 2 depicts some of these anomalous trends.

Figure 2: NSM Black Diamond Soil Geochemical Survey

More recent geochemical soil sampling from the Black Copper area yielded excellent results. Forty-six percent of the 135 samples collected at this location have copper results that exceed 100 ppm (or 100 g/t). Notable copper values that were strongly anomalous (greater than 97th percentile) analyzed from this location resulted in 634 ppm, 503 ppm and 496 ppm.

Manganese levels indicated from the soil survey were anomalous with all sample results exceeding 100 ppm. Soils samples collected from the Black Copper area all had manganese levels exceeding 200 ppm (72 soil samples were in excess of 1,000 ppm or 0.1%). Manganese, which is often found in association with other notable metals such as lead, silver, zinc, copper and vanadium has been mined in the Globe-Miami, Arizona area. Although considered a “strategic mineral” in the United States, Manganese is predominantly sourced outside the United States, primarily from China and South Africa.

With ongoing Geochemical Survey activities, the Company anticipates that it will continue to identify significant metal anomalies on the property. Steve Gray, Vice President of Northern Sphere, states, “One of the more encouraging geochemical trends is the correlation between results indicating significantly elevated copper in association with elevated molybdenum levels, two metals found in association with porphyry copper environments.”

In support of a potential porphyry environment, O.M. Bishop mapped andesite porphyry in the Richmond Basin, while researching for his Master’s thesis, ‘Geology and Ore Deposits Richmond Basin, Gila County’.

Mr. Gray adds, “The Geochemical Survey covers only 10% of the Black Diamond Property and already we have encountered various significant anomalous metals. The property is located up gradient from Freeport McMoRan’s porphyry copper mines ensuring soil geochemistry results are local to Northern Sphere’s mineral claims.”

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.

During October, Northern Sphere personnel is focusing on geochemical grid sampling efforts on the documented copper anomalies located on the Black Diamond Property. An area of particular interest to Northern Sphere is a documented iron-copper-gold showing which had a Permit to Drill previously submitted to the Forestry Department.

Buckeye Patent – Diamond Drilling

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.
