Shefa Yamim finds high grade Spinel
Spinel, Ilmenite, and Garnet added to Gem Box Suite of potential
commercial stones
Shefa Yamim (LSE: SEFA), a precious stone exploration company in
Northern Israel, announces that it has updated its Target Mineral
Assemblage ("TMA"), following the results of its 14 bulk sampling
campaign at the Kishon Mid-Reach Zone 1. The TMA recovered from the
6,384 tonnes sampling campaign in Zone 1 increased from a total of
5,825.24 carats ("cts") to a new total of approximately 9,778.15
cts enabling the original TMA to be updated to a predominantly
gemstone suite (99.5%) of potentially 9 gemstone minerals,
including the new addition of spinel, often found in large
crystals. Spinels come in different colours such as red, black,
violet, and the very rare blue.
Highlights from Bulk Sampling Campaign at the Kishon Mid-Reach
Zone 1
-- Increase in total gemstone minerals to date by 99.5% to 9,778.15 cts
-- Spinel becomes the 9th gemstone to be added to the TMA suite
following a recovery of 3,952.91cts
-- Cutting and polishing confirms gemstone quality of garnets, a
total of 2,176.77 cts were recovered
-- DMCH Suite renamed to 'Gem Box' to reflect the addition of the new gemstone minerals
-- Garnets re-assigned to the 'Gem Box' suite from the original
HIM suite of heavy minerals made up of garnet, ilmenite, zircon and
rutile ("HIM")
-- Ilmenite greater than or equal to 1mm, was also re-assigned
to the 'Gem Box' suite from the HIM suite as it is found to be of
gemstone quality, a total of 768.86 cts were recovered
-- The revised TMA, dominated by the Gem Box suite, is comprised
mainly of minerals that are <=0.65 cts/stn (85%) with 15% being
>=0.65cts. The largest gems recovered were: Carmel sapphire(TM)
33.3ct, garnet 13.6ct, sapphire 5.7ct, spinel 6.2ct, hibonite 2.8ct
and ruby 1.7ct
-- The overall TMA grade was some 153 cpht (at a bottom screen
size of 1 mm), with the grade dominated by 4 Gem Box suite
minerals: spinel (69.91 cpht); Carmel sapphire(TM) (39.36 cpht);
garnet (34.09 cpht) and ilmenite (12.06 cpht).
Commenting on the results Avi Taub, CEO of Shefa Yamim,
said:
"This is an excellent start to our campaign as we move towards
trial mining at the Kishon Mid-Reach Zone 1 and progress with Zone
2. The discovery of a 9(th) gemstone, Spinel, at our project in
northern Israel, coupled with the re-classification of ilmenite and
garnet to the newly created 'Gem Box', further cements our position
as a unique multi-commodity explorer.
"Shefa Yamim's gem-box contains very rare gemstones which will
form the basis of jewellery which, once manufactured, will be
marketed, due to their provenance, as 'gemstones from the Holy
Land'. We look forward to updating the market in due course."
RECOVERED GRADES & PRELIMINARY SIZE DISTRIBUTION OF THE TMA
SUITE IN ZONE 1, KISHON MID REACH ALLUVIAL PLACER
-- With the "new" gem minerals added to the original "DMCH"
suite, viz., garnet, ilmenite and spinel, this higher value
collection has been renamed the "Gem Box" suite to reflect the
>=95% gem contribution in Zone 1 of the Kishon Mid Reach
alluvial placer.
-- In the revised TMA, only 2 minerals thus fall into the "HIM"
industrial category (0.5%): zircon (which may also be a gem at
larger sizes) and rutile (Table 1).
-- The revised TMA, dominated by the Gem Box suite, is comprised
mainly of minerals that are <=0.65 cts/stn (85%) with 15% being
>=0.65cts. The largest gems recovered were Carmel sapphire(TM)
33.3ct, garnet 13.6ct, sapphire 5.7ct, spinel 6.2ct, hibonite 2.8ct
and ruby 1.7ct.
-- As Zone 1 has been mapped out as a geologically and
geomorphologically "homogenous" section of the Kishon Mid Reach
alluvial placer (notwithstanding the expected nugget effect in a
natural alluvial system), the results of the 14 bulk samples have
been combined per placer mineral to give average recovered grades
of these minerals as a first-pass estimation in this Zone (Table
1). The overall TMA grade was some 153 cpht (at a bottom screen
size of 1 mm), with the grade dominated by 4 Gem Box suite
minerals: spinel (69.91 cpht); Carmel sapphire(TM) (39.36 cpht);
garnet (34.09 cpht) and ilmenite (12.06 cpht).
-- The spatial positioning of the bulk samples from south to
north along much of the length of Zone 1, as well as their layout
approx. perpendicular to palaeo-flow direction of the ancient
Kishon in places, will allow for better geostatistical analyses of
the grade and size distribution of the Gem Box and HIM industrial
minerals in Zone 1 that will be presented at a later stage.
TARGET MINERAL ASSEMBLAGE SUITE & A REVISION OF THE GEM -
INDUSTRIAL MINERALS COMPRISING THE TMA IN ZONE 1 OF THE KISHON MID
REACH ALLUVIAL PLACER
The combined gem and industrial mineral component of the Kishon
Mid Reach alluvial placer is referred to as the Target Mineral
Assemblage. The "DMCH" gem suite made up of Diamond (extremely rare
and mostly small, <1 mm stones; only one record from the Kishon
Mid Reach alluvial placer from borehole SY-18), Moissanite (SiC, a
rare mineral globally of which the Shefa Yamim prospects host the
most abundant and the largest size natural moissanite in the
world), Corundum gem varieties namely, Carmel sapphire(TM) (to
date, a sapphire type known only from Mt Carmel and the Kishon
Valley alluvial deposits), sapphire and ruby, and Hibonite (another
rare gem).
However, with the last of the 14 bulk samples processed to
completion by late April 2018, the combined total of 6,384 tonnes
from Zone 1 yielded a large number of stones and carats per mineral
species of the original TMA suite as defined above (5,825.24
carats, cts). This provided an opportunity to review the status of
the original TMA, in particular the large garnet (2,176.77 cts) and
ilmenite (768.86 cts) populations, as well as the most abundant
potential gem mineral recovered to date, viz., spinel (3,952.91
cts). This investigation demonstrated that:
-- The garnet population, which is not of the more common
metamorphic origin but was sourced from deeper levels by the
Cretaceous Mt Carmel basic to ultra-basic volcanic complexes, is of
a gemstone and not an industrial quality. These garnets, which also
form an integral part of the so-called Kimberlitic Indicator
Minerals (KIMs) suite, were tested further by cutting and polishing
several stones, the results of which confirmed their gem quality.
Therefore, the Kishon alluvial placer garnets are no longer
considered part of the original HIM suite and have been re-assigned
to Gem Box suite.
-- The ilmenite, which is also a KIMs mineral, but is generally
finer-grained than the garnet, was likewise studied and found to be
predominantly of a gemstone and not of an industrial quality.
Therefore, the ilmenite population in the Kishon Mid Reach Placer
has also been re-assigned to the Gem Box suite from the original
HIM suite.
-- Significantly, and in addition to the original TMA suite
(described above) that is the focus of the Shefa Yamim Recovery at
the Akko facility, the Recovery personnel also pick spinel and
other remaining KIMs (e.g. clinopyroxe, chromium diopsides, etc) as
a matter of routine. Significantly the Zone 1 placer gravels
yielded a considerable quantity of spinel, most of which was gem
quality and relatively coarse-grained (3,952.91 cts). Thus spinel
has been added as an additional mineral to the original TMA
suite.
-- The TMA now comprises of 9 gemstones (in order of abundance):
spinel, Carmel sapphire(TM), garnet, ilmenite, sapphire, hibonite,
moissanite, ruby, diamond (not recovered in the Zone 1 bulk sample
campaign and only known from borehole SY-18 in Zone 2); and 2
industrial minerals: zircon and rutile.
