Silver Spruce Resources Inc. (TSXV:SSE) announced preliminary mineralogical studies from the Big Easy gold/silver prospect in eastern Newfoundland.

As quoted in the press release:

Native silver (Ag), electrum (Au/Ag), acanthite (Ag2S) and unidentified silver-sulfide-selenide (Ag-S-Se) minerals are noted, mainly in “ginguro” bands (narrow erratic black bands) in banded silica (quartz) veins. The Ag-S-Se minerals occur as very fine disseminations (2-3 microns) enclosed within pyrite (FeS2), while the native silver, electrum and acanthite are found as discrete polyminerallic grains up to 30 microns in size, averaging 10-15 microns. A sample of core from the brecciated, gold/silver rich section in DDH BE-11-3 showed one 200 micron grain of pyrite with native Ag, electrum and acanthite in fractures, which is different from numerous smaller pyrite grains in the same polished section – indicating that it may have been re-emplaced from another zone deeper in the system during the periodic re-activation of the boiling / hot spring system. The native Ag-electrum-acanthite mineral assemblage is also associated with well preserved boiling textures (bladed features – quartz after calcite) as shown in a sample from DDH BE-12-10.

Silver Spruce’s  President and CEO, Peter Dimmell, said:

The mineral assemblages and vein textures are characteristic of an epithermal, low sulphidation, gold/silver system, like many others world-wide, especially Nevada (Sleeper, Round Mountain) and Japan (Hishikari), where silver selenide minerals are found. The brecciated zone in DDH BE-11-3, with the isolated grain showing different characteristics from the rest of the grains may indicate better potential for Bonanza grades, typical of these systems, at depth.
