Pangolin Diamonds Corp. (TSX-V: PAN) (“the
Company” or “
Pangolin”) wishes to
update shareholders on recent activities at its various projects in
the Republic of Botswana, Africa.
Highlights Include
- Positive drill results at Kweneng
- 52.5% of chromites recovered from soils at Kweneng
indicative of diamond stability field
- 68 aeromagnetic targets identified at Motloutse and
Malatswae
Kweneng
Drilling intersected a shallow (< 1 m
overburden) phlogopite and clinopyroxene rich ultramafic hypabyssal
dyke of approximately 6m in true width. Processing of 25 kg drill
chips through Pangolin’s in-house 1 TPH DMS plant produced
chromite, clinopyroxenes, and what is interpreted as fragments of a
chromite-garnet peridotite. The Kweneng Project is located about 20
km north of Botswana’s capital, Gaborone.
The dyke material is highly altered and is
currently interpreted as a phlogopite-rich lamprophyre - similar to
the diamondiferous lamprophyres discovered by Southern Africa
Minerals Corporation in 1998 approximately 33 km to the north.
Pangolin’s samples will be submitted for petrographic
identification.
This discovery came on the back of an extensive
soil sampling program that identified a chromite anomaly measuring
approximately 850 m x 250 m. Based on the indicator distribution
and the relative location of the dyke, it is expected that more
dykes may be present in the area. A soil sampling programme will
continue once the lockdown is lifted to determine the horizontal
extent of the dyke, locating any diatreme structures associated
with the dyke as well as locating additional dykes within the KW04
area.
Dykes have been mined in South Africa for
diamonds to depths exceeding 1000 metres below the surface.
Significant diamonds mines have been established on the Bellsbank,
Bobbejaan, Ardo, Helam, Roberts Victor, Star and Klipspringer
dykes. Economic kimberlite dykes normally average 60 cm – 80
cm in width and tend to maintain their width and grade with
increasing depth.
Chromites have been identified as diamond
inclusions in West Africa, Dokolwayo in Swaziland, the five mines
in Kimberley, Roberts Victor Star (all in South Africa), the Diavik
kimberlite in Canada and Murowa as well as River Ranch in
Zimbabwe.
A total of 326 kimberlite indicator minerals
from surface soil samples (KIMs) were submitted to C.F. Mineral
Research (CFM) in Kelowna, BC, Canada for microprobe analysis. C.F.
Mineral Research Ltd. is certified ISO 9001:2015 and compliant with
ISO 17025:2005
52.5% of chromites analyzed were classified as
being derived from a “diamond friendly” environment in the
mantle.
- 23% classified as CR DI; Chromite with major element
diamond-inclusion composition
- 29.5% classified as CR DI*; Diamond-Inclusion Chromite from
favorable harzburgite source
Chromites with Cr2O3 in excess of the
stoichiometric limit of 67.9% Cr2O3 comprised 5.5 % of the
population, thus indicating a derivation from a highly oxygen
reduced environment which is favorable for the formation of
diamonds.
The significance of chromites in diamond
exploration was recognized in a publication by Griffin et al (1991)
where it was stated:
“The high proportion of chromites as inclusions
in diamonds from the producing mines in Siberia suggests that
disaggregated chromite peridotite can make a major contribution to
the overall diamond content of at least some kimberlites. Diamond
inclusions also show that important contributions from chromite
bearing rocks have occurred in West Africa, at Dokolwayo in
Swaziland, at the five mines in Kimberley, at Roberts Victor and at
Star (all in South Africa). No doubt there are many other
examples.”
Subsequent to this publication, chromites have
been identified as diamond inclusions in the Diavik kimberlite in
Canada and Murowa and River Ranch in Zimbabwe.
COVID-19
Fieldwork in Botswana ceased at the end of March
due to a nationwide lockdown. The lockdown is currently extended to
08 May but may be further extended depending on the spread of the
virus in the country. To date, there are 23 confirmed COVID-19
cases in Botswana.
Pangolin has used its time during the lockdown
for reviewing all existing data and for planning future field
programs. Preparations are made to commence exploration as soon as
the lockdown is lifted.
Motloutse and Malatswae
Aeromagnetic data over the Malatswae and
Motloutse Project areas has been reviewed extensively. As a result,
38 aeromagnetic targets in the Motloutse Project area and 30
targets in the Malatswae Project area were identified for follow-up
with groundmagnetic surveys and soil sampling. Once the targets
have been followed up on the ground, the top twelve selected
targets, based on magnetic and soil sample results, will be
drilled.
AK10 Kimberlite Pipe
Due to the close working distances required at
the AK10 kimberlite, work at the project has been suspended until
such time that the Botswana Government lifts all social distancing
requirements related to the COVID-19 virus.
