Shefa Yamim (A.T.M.) Ltd (LON:SEFA) has reported “encouraging” results from the first bulk sample collected at the Kishon Mid-Reach Zone 2 site.

The Israel-focused precious stone explorer said the BS-1230 bulk sample, the first of five collected at the end of 2017 to determine a potential resource, was dominated by gemstones at 99%, with spinel accounting for 57% of the target mineral assemblage (TMA) followed by garnet at 18%, ilmenite at 15%, sapphire at 5%, Carmel Sapphire at 3% and hibonite, moissanite and ruby comprising the remaining 2%.

The largest gemstones recovered in the sample were a 6.2 carat spinel and a 3.61 carat garnet, with the company adding that the sample represented a “significant increase” in the overall grade following the update of its TMA to include spinel in the Kishon Mid-Reach placer gemstones assemblage and with the formation of a revised "Gem Box" suite that incorporates 9 gemstones.

A total of 1,380.69 carats of gemstones were recovered from 568.9 tonnes of basal gravels with an overall TMA recovered grade of 242.69 carats per hundred tonnes at a bottom screen size of 1mm.  Of this, the "Gem Box" suite comprised 99% of the TMA, with the heavy industrial minerals (HIM) suite of zircon and rutile accounting for the balance of 1%.

The company added that the addition of spinel into the Gem Box suite at the site had resulted in a significant increase to the overall TMA grade of the BS-1230 sample.

The news follows previous results from bulk sampling at the group’s Kishon Mid-Reach Zone 1 site last week, in which it boosted the number of carats recovered to 9,778.15 from 6,384 tonnes of ore sampled.
