Hier die beiden momentanen Projekte, die aber wie gesagt, meiner
Meinung nach zukünftig nur eine untergeordnete Rolle spielen
werden, aber laut Eckhof dennoch sehr gute Grade aufweisen, hier
ist sicherlich ein JV oder ein farm-in denkbar:
Elemental Minerals has two projects in the Kimberley and
Forrestania regions of Western Australia.
The Kimberley Project, which is made up of two granted Exploration
Licenses and four pending exploration licenses, covers one of the
largest sill complexes in the world. Such large volumes of mafic
magma are indicative of sustained plume activity from a mantle
source, a setting that has similarities to Noril’sk, one of the
larger mineral deposits in the world. In addition, the copper
occurrences within the Carson Volcanics in the same tenement group
show similarities to Zambian type copper mineralisation.
The Forrestania Project, made-up of two granted Exploration
Licenses, encompass a concealed interpreted, greenstone target that
is prospective for nickel sulphide (and possibly gold)
mineralisation. They also represent a strategic position in an area
that is thriving with exploration activity and previously
unrecognised potential.
Elemental Minerals plans to spend approximately $1.8M in the first
two years after listing to explore for precious and base metals
including uranium, PGE’s and gold at the Kimberley Project and
nickel and gold at the Forrestania Project. In addition to
exploring and developing its current projects, the Directors will
assess and pursue other valid economic opportunities in mining and
exploration.
Kimberley Project
Kimberley Project - Prospective for Base Metals, Uranium, PGE,
Gold
The Kimberley tenements located approximately 120km northwest of
Halls Creek comprise two granted exploration licenses E80/3277 and
E80/3278, covering a total of 136 blocks. Four applications are
currently pending approval (ELA’s80/3445-8) in the same area
covering 70 blocks each.
The project areas have seen sparse exploration throughout history.
The area was explored during the 1970’s for base metals and
uranium, and more recently for copper and gold. These programs
concentrated on the Carson Volcanics, King Leopold Sandstone and
Elgee Sandstone. The tenements contain prospective units such as
the Carson Volcanics and the Hart Dolerite. These units represent a
phase of intracratonic rifting resulting from mantle-plume activity
and as such have the potential to host base metal sulphides with
associated PGE’s and gold. The Carson Volcanics represent extruded
lavas and interbedded sediments related to the intracratonic
rifting and have the potential to host stratabound copper
mineralisation, lead, zinc, gold silver and PGE’s. The Hart
Dolerite is a series of massive tholeiitic dolerite sills and
granophyre intrusions containing trace chalcopyrite and
hydrothermal veins of base and precious metals. This unit
represents the driving force behind the intracratonic rifting. This
intracratonic rifting system has been recognised previously but
only recent conceptual modelling of other such systems has
highlighted its significance as a potential host for large metal
deposits. Tectonic models suggest a regime of subduction and
compressive forces prior to pluming, with these forces creating
structural pathways that possibly, but not necessarily, aided the
thermal evolution of the plume as it heated the underside of the
plate. Sill complex emplacement through the basinal sediments and
limestone reef systems should result in enhanced sulphur
concentration to a point where saturation occurs developing
sulphide accumulations in the basal sections of the sill similar to
the Noril'sk style of metal deposition. Tenements were applied for
with the aim of blocking out a large section of this orogenic belt
as the Company believes it has significant potential to host large
mineral deposits.
Previous Exploration 1968 - 1971: Previous exploration discovered
copper mineralisation within the Carson Volcanics during 1968.
Several prospects were actively explored until 1971 under an
exploration joint venture. Exploration during this time was limited
to gridding, geological mapping, stream sediment, soil and rock
chip geochemistry. Samples taken from around Carson 1, located
within the project tenements, were analysed for copper only, the
maximum reported result was 5%. Regional exploration in the area
concentrated on base metal and uranium targets.
2001 - 2002: A compilation, review and analysis of previous
exploration activities was undertaken while acquiring air photos,
Landsat and digital topographic images. Exploration in the field
was limited to 16 multi-element (Au, Ag, As, Bi, Cr, Cu, Fe, Mo,
Ni, Pd, Pt, Sb, Se and Zn) stream samples analysed by Genalysis and
rock chip sampling (17 samples) conducted over copper bearing
exposures. The rock chip samples were analysed for Au, Ag, As and
Cu utilising Aqua-Regia digest with a flame AAS or solvent
extraction finish. Several high copper results (up to 5% Cu – rock
chip), anomalous silver (8.1g/t Ag – rock chip) and bismuth
(2.46ppm Bi – stream sample) were reported. The gold content was of
a low order (0.09g/t Au - rock chip) and as such the project did
not appear to warrant further exploration and the tenement was
released.
Forrestania Project
Forrestania Project - Prospective for Nickel and Gold
The Forrestania tenements are located approximately 140km east of
Hyden, proximal to the Lake Johnston Greenstone Belt in Western
Australia. The Forrestania Project comprises two granted
exploration licenses E63/880 and E63/881, covering a total of 64
blocks. Access to the area can be obtained from the Hyden- Norseman
unsealed road. This road directly crosses E63/880 and runs just to
the north of E63/881. The Forrestania and Lake Johnston districts
are being actively explored for nickel sulphide mineralisation by
other companies.
Recent discoveries of nickel sulphides have occured at the Flying
Fox, Emily Ann and Maggie Hays projects. The Project Tenements lie
to the south and south west of the Maggie Hays deposit, and have
interpreted structural targets and the likelihood of covered
greenstone sequences. Previous Exploration Little exploration has
occurred over the project tenements though regional programs during
the 1980’s indicate that greenstones were present in the area (just
north of E63/880). It is apparent from other exploration activities
that covered greenstones occur in this region that have gone
unrecognised until now. Exploration in the area has been hampered
by the surficial cover prevalent in the area and preconceived ideas
regarding underlying stratigraphy.
Geology
The Lake Johnston greenstone belt is narrow and outcrops poorly
over 200km. The majority of the belt is covered by laterite, thin
colluvium and wind blown sand. Exploration for nickel resources
commenced in the 1960’s, with the successful delineation of nickel
sulphide and disseminated mineralisation following over the next 30
years. The greenstone succession of basalt has been intruded by
mafic to ultramafic intrusions generally parallel to layering. This
is overlain by various sediment units including a banded iron
formation, which is in turn overlain by felsic volcanics. The belt
is bounded by the Koolyanobbing fault to the east and is complexly
faulted resulting in some stratigraphic repetition caused by
thrusting. Late stage dolerite dykes cut the sequence east-west as
does some quartz veining. Mineralisation is related to ultramafic
and felsic volcanic units which contain both nickel sulphide and
disseminated mineralisation styles. Tectonic activity post
emplacement has caused remobilisation along structures, lineaments
and litholigcal contacts.
Recent exploration has uncovered previously unknown rafts of
greenstone that are prospective for nickel sulphide mineralisation.
These units are interpreted to pass through the project tenements.
Exploration Potential The Lake Johnston and Forrestania Regions
have in recent years been subjected to active and sustained
exploration for mainly nickel sulphide mineralisation. Regional
aeromagnetic, new stratigraphic information and identified
structural corridors indicate the possibility of favourable
stratigraphy within the project tenements that could host nickel
sulphide mineralisation. The intersection of ultramafics proximal
to the project tenements outside previously recognised greenstone
belts further supports the areas prospectivity. Both tenements have
the potential to host orogenic vein gold, nickel, heavy mineral
sands and diamonds.
