Shefa Yamim completes bulk sampling campaign in Zone 1 of the
Kishon Mid-Reach
Shefa Yamim (LSE: SEFA), a precious stone exploration company in
Northern Israel, announces it has completed its bulk sampling
campaign at the Kishon Mid-Reach Zone 1, following the exploration
results from bulk samples BS-1208 and BS-1228, the last two bulk
samples from a fourteen-bulk sample campaign carried out in Zone
1.
Strategy Highlights
-- Shefa Yamim has been concentrating its efforts on an alluvial
deposit where coloured gemstones are more frequent and potentially
higher yielding rather than exploring for the primary source.
Alluvial gemstone deposits typically have lower operating costs and
although the geological certainty associated is lower, these mines
typically yield higher quality gemstones than primary deposits
-- As a consequence, Shefa Yamim has focused its efforts on the Mid Reach Zone with:
o 137 drill holes (total of 1,378.4 metres drilled) and 14 bulk
samples (total of 6,385 tonnes) in Zone 1 and;
o 23 drill holes (total of 249 metres drilled), so far, and 25
bulk and mini bulk samples in Zone 2 (total of 3,793 tonnes);
o Total of 10,178 tonnes from bulk and mini bulk samples so far
from the Kishon Mid Reach Zone 1 and 2
The Company has started processing bulk samples collected during
August and September 2017 from the Kishon Mid-Reach Zone 2, as it
continues to assess the resource potential of the Kishon Mid-Reach.
In total, the Company will be processing five bulk samples
consisting of 2,900 tonnes of gravel.
Bulk Sample Summary for BS-1228 and BS-1208
-- Smallest bulk samples taken from the Kishon Mid-Reach Zone 1,
in comparison to previous bulk samples of 500 tonnes
o BS-1228 - bulk sample of 249 tonnes
o BS-1208 - bulk sample of 123 tonnes
-- Sapphire was the dominant gem mineral from BS-1228, with the largest sapphire 3.04 ct
-- 0.88 ct sapphire recovered from bulk sample BS-1208
-- Bulk Samples 1208 and 1228 mark the end of a fourteen sample
bulk sampling programme at the Kishon Mid-Reach Zone 1
-- The variation in overall grades is what might be expected for
a placer with semi mobile trapsites
Bulk Sample Details:
Bulk samples BS-1228 and BS-1208 mark the end of a bulk sampling
campaign to determine a resource estimate in Zone 1 of the
multi-commodity target mineral assemblage ("TMA Suite") in the
Kishon Mid-Reach exploration area. The samples consisted of 249
tonnes and 123 tonnes of basal gravel respectively. Shefa Yamim's
TMA has two sub categories; the DMCH Suite consisting of Diamond,
Moissanite, gem Corundum species (sapphire, ruby and Carmel
Sapphire(TM)) and Hibonite and the HIM Suite, consisting of the
heavy industrial minerals: garnet, ilmenite, zircon and rutile.

Sapphire was the dominant gem mineral from BS-1228 with the
largest sapphire 3.04 ct. The results are in line with previous
bulk sample results in Zone 1 to date, with the exception of
BS-1212, in that the TMA in BS-1228 was dominated by the HIM Suite
(85%).
In contrast, but in keeping with the majority of the earlier
bulk samples, BS-1208 results were dominated by the Carmel
Sapphire(TM) (37%), followed by the sapphire (16%). Although no
diamond, moissanite, ruby or hibonite were recovered from BS-1208,
this bulk sample was unusual, but similar to BS-1212, in that the
TMA was dominated by the DMCH suite (53%). The HIM suite (47%) was
also unusual in BS-1208 in that only garnet (36%) and ilmenite
(11%) were recovered with zircon and rutile seemingly absent.
The largest gemstone recovered from BS-1208 was a 0.88 ct
sapphire. Although a comparatively small stone, this size is in
keeping with the lowest TMA grade returned so far in Zone 1, viz.
7.93 cpht for BS-1208, pointing to immature trapsite development at
that locality in Zone 1.
The variation in overall grades is what might be expected for a
placer with semi mobile trapsites. The TMA was represented by all
minerals except for diamonds, which have only rarely been found in
the Kishon Mid Reach area.
Avi Taub, CEO of Shefa Yamim, said: "We are delighted to mark
the end of Bulk Sampling in Zone 1, which consisted of processing
over 6375 tonnes of material which confirmed the presence of
diverse gem minerals. We have started processing bulk samples
collected from Zone 2 and expect to process five bulk samples
consisting of 2900 tonnes of gravel. We look forward to reporting
on our progress as we continue to assess the resource potential of
the Kishon Mid-Reach area."
