Advanced Metallurgical Group NV has completed the sale
of a 40% equity stake in AMG Graphite
Kropfmuhl to an affiliate of Alterna Capital
The transaction was completed on 30 March. Germany-based AMG
Graphite Kropfmuhl, known as GK Graphite,
recently entered a strategic partnership
with ASX-listed Triton Minerals
Ltd through its subsidiary, GK Ancuabe Graphite Mine
SA, to explore for graphite deposits in the Ancuabe
region of Mozambique.
Australia-headquartered Kibaran Resources
Ltd has retracted a statement relating to a 55%
increase in the net present value (NPV) of its Epanko graphite
project in Tanzania, which pegged the project at
The figure, released on 8 April, was based on calculations made
by professional evaluation firm The CloudMiner Ltd
and assumptions contained in an updated Epanko scoping study
released in August last year.
The company issued an update today, however, saying that the
revised sum "contained a significant formula error and hence
overstated the Epanko project NPV".
"For avoidance of doubt, the company retracts all references to
the NPV calculations made in yesterday’s
announcement," Kibaran added.
"Based on current indications, which include a corrected
re-calculation by CloudMiner utilising the updated Epanko
scoping study and indicative terms proposed for the project
(…) as announced on 27 March 2015, the company expects
that the pre-tax project NPV of $213m (…) will improve
in the coming [bankable feasibility study]," Kibaran
Also in Tanzania, fellow ASX-listed IMX Resources Ltd
has released a maiden inferred mineral resource for the Shimba
deposit at its Chilalo graphite project.
The inferred resource for Shimba stands at 7.4m tonnes graphite
grading at 10.7% C, for 792,000 tonnes contained graphite
within the sites high grade (>5% C) zone.
IMX said that over 90% of the mineral resource lies within 100
metres of surface and that there is significant potential to
further increase the high grade resource base, as the Shimba
deposit remains open to the northeast and southwest.
The company expects to begin a prefeasibility study at Chilalo
this quarter and earlier this week raised Australian dollar
(A$) 1.57m ($1.2m*) from a placement of 157m shares at a price
of A$0.01/share to advance the project.
Elsewhere in Africa, TSX-V-listed DNI Metals Inc.
has said that the results of further tests on grab samples
recently collected at its Madagascan graphite property have
indicated jumbo and large flake distribution of over
Grades for the samples range from 91.3% C for large flake to
97.9% C for jumbo flake. Small and medium flakes, which account
for 37.5% of the deposit’s distribution, have
grades ranging from 87.3-89% C.
DNI has also filed a notice with the TSX-V to complete a
non-brokered private placement of up to 12.5m common shares at
a price of Canadian dollar (C$) 0.16/share ($0.13/share) for
gross proceeds of C$2m, to be used for corporate cash flow
In the US, A
labama Graphite Corp
. has received positive assay results from a trenching
programme carried out at the Bama mine project in Chilton
The trenching programme identified new targets with a number of
sections averaging over 3% C, based on previously outlined
airborne geophysical anomalies and targets from surface channel
Alabama Graphite also collected bulk samples from the property
and is preparing composite samples to undertake metallurgical
testing from some of the key trench intercepts.
TSX-V-listed Nouveau Monde Mining
Enterprises has completed a short core drilling
programme on its Matawinie graphite property, located
approximately 140km north of Montreal in Quebec.
The campaign was designed to test both the extent at depth of
graphite mineralisation discovered during ground prospecting in
2014 in the northern sector of the property, as well as a
number of distinct conductors.
The programme consisted of seven boreholes totaling 675.7
metres, from which 135 split-core samples were collected and
sent to the ALS Minerals’ laboratory in Val D'Or,
Quebec, for graphite and multi-element analysis.
The results are expected by the end of April and will be used
to plan the next development stage of the project.
Canada-listed Graphite One Resources
Inc. has changed the name of its Alaska, US-based
subsidiary company to Graphite One (Alaska) Inc. from Cedar
Mountain Exploration (Alaska) Inc., effective
The company, which is developing the Graphite Creek graphite
deposit on Alaska’s Seward Peninsula, also
announced that its board of directors has approved an incentive
stock option grant to its chief financial officer, Alan
Ahlgren, for the purchase of 500,000 shares of Graphite One at
an exercise price of C$0.13/share. All shares vest immediately
and expire on 2 April 2020.
Big North Graphite Corp
. has issued a corporate update stating that the
company’s management and its consultants TetraTech have
determined that one line of the El Tejon graphite mine
and mill site in Mexico can be restarted in a six month period
at a cost of approximately $2.5m.
The Vancouver, Canada-headquartered explorer said that a second
processing line would be re-started in an orderly manner in
line with initial operating experience.
"In recognition of the vital importance of offtake agreements
in the industrial minerals industry, the company has initiated
the process of securing such agreements," Big North
It added that a quantity of bagged graphite product from the
mine’s previous operation remains on the El Tejon
site and is being submitted to two potential offtake candidates
for evaluation and quality assurance purposes.
Canadian technology firm Grafoid Inc. has
entered into an agreement to acquire Hamburg, New Jersey-based
Corp., a company which develops and produces
speciality elastomeric materials used in the defence,
automotive, aerospace, personal protection and industrial
"Our purpose in acquiring Ames is to broaden Grafoid’s
opportunities by bringing our Mesograf graphene materials into
an established, high-value market through a diverse range of
elastomeric materials, working with and through an experienced
team of engineers and scientists," said Grafoid’s
CEO, Gary Economo.
"We see Ames as our springboard into the $700bn rubber and
plastics market — a market in which we believe Grafoid
can become a major influence," he added.
Terms of the agreement were not disclosed. The acquisition is
expected to close in the second quarter of 2015.
The UK’s National Graphene
Institute (NGI) has named
NASDAQ-listed Bruker Corp. as an
official partner as the institute works towards its goal of
commercialising graphene materials.
The NGI, which is part of the University of
Manchester where graphene was first isolated in 2004,
previously purchased seven atomic force microscopes from
The partnership will see the US-based technology provider
partially sponsor a PhD student at the NGI working on novel
scanning probe microscopy techniques to characterise graphene
and other 2D materials.
Sri Lanka-focused MRL Corp. has
signed a contract with Adelaide Research and
Innovation Pty Ltd, the commercial development arm of
the University of Adelaide in Australia, to test the potential
of graphite extracted from its Sri Lankan deposits for
scaleable graphene production.
"The tests will seek to determine the yield and quality of
isolated graphene within MRL’s graphite," the
Recent tests on MRL’s material have already shown
that the graphite is suitable for use in batteries.

graphene oxide, new research has shown.
China’s Nankai University
in Tianjin found that graphene oxide is "relatively
biocompatible", despite concerns that the
nanocarbon’s innate properties make it a prime
nanomaterial contaminant for soils.
According to a
report by Chemistry

exhibiting nitrogen-fixing functions. These were found to be
