Pangolin Drills into Kimberlite Dyke, Botswana Africa; Mini-Bulk Sample of 100 Tonnes Planned to Determine Diamond Content
31 July 2018 - 11:00PM
Pangolin Diamonds Corp. (TSX-V:
PAN) (the "Company" or "Pangolin") is pleased to
provide an update on the drilling programme at Pangolin’s 100%
owned Malatswae Diamond Project, Botswana, Africa.
- Two diamonds recovered at surface
in excess of 1mm in long axis size
- BH1 - Kimberlitic garnets with
Class 1 surface textures recovered at a vertical depth between 21.6
and 26.9 m
- BH2 - Kimberlitic garnets with
primary surface textures recovered at a vertical depth between 47.6
m and 52.8 m
- BH3 - Kimberlitic garnets with
primary surface textures recovered at a vertical depth between 21.6
and 26.9 m
- The combination of the soil sample
and drilling results are indicative of a diamondiferous kimberlite
dyke system at MAL 001
- Once core drilling is completed, a
mini-bulk sample of at least 100 tonnes will be undertaken to
determine the diamond content for the kimberlite
Following a 24-month soil sample programme
sampling the same 4 hectare grid monthly, a well defined kimberlite
indicator anomaly was identified in the MAL 001 area of the
Malatswae Diamond Project. The indicators were analysed and
reported on 08 May 2018 (see news release – May 8 2018). The
majority of the indicators analysed are garnets (93) and consist
predominantly of peridotitic garnets which include 4 x G10
garnets and an additional 41 garnets consistent with a derivation
from the diamond stability field.
Two diamonds, both in excess of 1mm in long axis
size, were also recovered from the soil samples at MAL001.
The presence of the diamonds is consistent with the observed garnet
compositions above.
A detailed groundmagnetic survey has been
completed over the 4 hectare area and no magnetic anomaly is
present. The distribution of the recovered diamonds and
indicators are concentrated in the central part of the area covered
by the groundmagnetic survey and suggests that the source of the
indicators extends beyond the northern and southern limit of the
survey area.
Borehole MAL 001/BH1 was drilled with an air
percussion drill at an angle of 60 degrees from the horizontal in a
southwesterly direction to intersect possible source rocks below
the indicator anomaly. Geological logging of the percussion
chips from this borehole indicate that Kalahari sediments depth and
the top of the surrounding Karoo rocks is at a vertical depth of
17.3m at this position. Samples were collected on a 6m interval
basis and processed through a mini-DMS 1 tph plant for indicator
minerals. Garnets with Class 1 surface textures were
recovered from the drilled material between the drill hole depth
intersection of 25m to 31m, which is equivalent to a vertical depth
between 21.6 and 26.9 m.
Boreholes MAL 001/BH2 and MAL 001/BH3 were
drilled 50 metres to the south east from MAL 001/BH1 with an air
percussion drill at an angle of 60 degrees from the horizontal in a
northeasterly direction to intersect possible source rocks below
the indicator anomaly. Samples were collected on a 6m
interval basis and processed through a mini-DMS 1 tph plant for
indicator minerals.
Garnets with primary surface texture were
recovered from the drilled material of borehole MAL 001/BH2 between
the drill hole depth intersection of 55m to 61m, which is
equivalent to a vertical depth between 47.6 m and 52.8 m.
Borehole MAL 001/BH3 was drilled 15 m to the
northeast of borehole MAL 001/BH2. In both holes, geological
logging of the percussion chips from this borehole indicate that
Kalahari sediments depth and the top of the surrounding Karoo rocks
is at a vertical depth of 19.0m at this position. Garnets with
primary surface textures were recovered from the depth interval of
25 to 31 m, which is equivalent to a vertical depth between 21.6
and 26.9 m. This positive recovery is vertically correlated
with the positive recovery of indicators in borehole MAL
001/BH2.
The combination of the soil sample and drilling
results are indicative of a diamondiferous kimberlite dyke system
at MAL 001. A systematic programme to assess the economic
potential of the dyke system will be undertaken. Initially, a
core drilling programme will be undertaken to determine the width
and extent of the dyke system. Once the core drilling
programme has been completed a mini-bulk sample of at least 100
tonnes will be undertaken to confirm and determine the diamond
content for the kimberlite.
In addition, following the Marsfontein model
where an enlargement was discovered on a diamondiferous dyke
system, a programme to search for an enlargement on the MAL 001
dyke system has commenced. Soil sampling will be extended to
the north and the south of the current sampling grid. An
extended groundmagnetic survey has produced an anomaly of
approximately 1.5 hectares on strike about 500 m to the southeast
of borehole MAL 001/BH3. A detailed soil sample programme
over the groundmagnetic anomaly has been initiated.
Kimberlite dykes have been successfully mined in
South Africa for more than sixty years. The Bellsbank dykes have
been mined for diamonds since 1956. Other kimberlite dyke
mines in South Africa are Swartruggens, Sover, Star and
Klipspringer. Enlargements in the form of small pipes have
been found at Bellsbank, Star and Marsfontein.
DRILLING UPDATE
Drilling on PAN Projects in Botswana continues
in the third quarter. Due to large sample backlogs at laboratories,
analytical results from the drilling conducted earlier in the year
have not been received. Results will be announced once the
analytical data is available and has been assessed.
