Northern Shield Resources Inc. (TSXV:NRN) announced the results from the first phase of rock sampling at the Shot Rock property, Nova Scotia. This includes analysis of three float samples of quartz vein material recently found exhibiting classic epithermal textures. Shot Rock is being explored through Northern Shields wholly-owned subsidiary, Seabourne Resources Inc, which can earn up to an 80 percent interest in the property.
As quoted in the press release:
Significantly, all of the above noted samples are highly anomalous in gold with assays of 0.29, 0.26 and 0.13 grams per tonne gold. Fragments, bands, and infillings of jasper within the banded quartz veins are a common feature. These sample are all from small angular float material collected along a 2 kilometre stretch of river bed. Several more samples have been collected on a recent return visit to the river and approximately fifty further angular to sub-angular pieces of jasper-banded and/or colloform-banded quartz were noted along a short stretch of the river. These samples contain very little sulphides with a maximum of 0.3 percent sulphides.
The textures and mineralogy of the quartz vein material are all very consistent with epithermal gold systems. Textures include colloform banded quartz (generally chalcedony), bladed carbonate with some samples showing quartz pseudomorphing the carbonate, comb textured quartz with jasper infilling and brecciated colloform chalcedonic quartz with jasper veins. Bladed carbonate textures suggest the vein material originates high up in the epithermal system, likely above the “boiling cap.”
Boiling caps form at the level where rising boiling fluids, which carry the gold, interreact with cooler near surface water (water table) with the result that epithermal quartz veins typically show significant and rapid vertical zonation in gold grades from low-grades above the cap to higher grades below.
The company has increased the size of the Shot Rock property by an additional 1,200 hectares, which now totals 19,700 hectares.
Assays are still pending for 197 stream sediment samples and a further batch of rock grab samples (including more collected from the river) have been shipped to the lab for analysis.
Follow-up rock and till/soil sampling is being planned for the area which will commence after interpretation of the pending assays.
Ian Bliss, president and CEO, commented:
In typical epithermal systems, one doesn’t see significant gold mineralization above the boiling cap even with the presence of the quartz veins. We believe the erosional level of Shot Rock is at, or above, the boiling cap. Hence, the highly anomalous gold values we are seeing bode well for what may be found at deeper levels of the quartz vein below the boiling cap. We believe there is high potential here since this style of mineralization has been historically unrecognized in this area
