VANCOUVER,
Aug. 13, 2013 /CNW/ - Tanzania
Minerals Corp. (the "Company"), (TSX-V: TZM) (FRANKFURT: TM0.F) is
pleased to provide a summary of exploration activities on their
extensive property portfolio in Tanzania.
Statement from the CEO
Kal Matharu, CEO
of Tanzania Minerals Corp. said, "We have been conducting field
work over the majority of our exploration portfolio and, encouraged
by preliminary field results at the Nyamwaga project, we intend to
commence a 3D induced polarization (IP) study to better delineate
the outlined target structure at depth. Shallow soil sampling
at Siga, within the Siga-Mabale Greenstone Belt, appears to have
identified a broad copper anomaly that we hope exhibits coincident
gold mineralization; the results of this survey are pending.
Other licences within our portfolio appear promising and additional
work is required to develop them further."
In 2013, the Company has conducted field
exploration on eight of its gold licences. This work mainly
consists of interpretation of airborne geophysics, geological
mapping, lithogeochemistry and shallow soil geochemistry.
Mrangi
Situated in the Musoma-Mara Greenstone Belt, the 10.47
km2 a drill programme at the Mrangi property was carried
out in 2011. Drilling highlights included long intercepts of
weak copper mineralization (43 m @ 0.14 % Cu) within rhyolitic
tuffs and also elevated gold concentrations (7 m @ 0.53 g/t Au)
present at the contact between a felsic tuff package and mafic
tuffs and lavas. Results of the deep overburden soil sampling
programme, conducted over a 1.4 km long zone adjacent to elevated
gold drilled intercepts, were obtained in April 2013 from the assay lab. Results were
disappointing with the highest gold assay being only 120 ppb, and
no clear trends identified from the 129 samples analysed. It
appears that the thickness of the organic-rich soil (mbuga) in the
area has profoundly affected the assay results, and rotary air
blast (RAB) drilling is being considered to test this zone.
Nyamwaga
This licence is located 5 km along strike from Africa Barrick
Gold's Gokona and Nyabigena pits in the Mara District, both of
which are concealed beneath thin flows of recent lava. Extensive
shallow soil sampling, including multi-element XRF analyses (1,637
samples) and gold assays (508 samples), in addition to 68 shallow
test pits have identified three anomalous gold-rich zones, with
gold concentrations up to 473 ppb. The strongest gold anomaly
is coincident with an interpreted magnetic lineament (deduced from
high resolution airborne geophysics) along the same trend as the
Gokona and Nyabigena pits.
Analysis of the soil geochemistry and
high-resolution airborne geophysics data has identified a 600 m
wide and 2,000 m long northwest-trending structure that is the
focus of ongoing exploration at Nyamwaga. The company has
decided to perform a 3D induced polarization (IP) survey to test
for conductors similar to mineralization currently being mined at
Gogoma and Kibanda pits.
Tabora
The Tabora licence covers an area of 163.18 km2 and is
underlain by late stage granites cut by mafic and alkali
dykes. In April, reconnaissance mapping and shallow soil
geochemistry (XRF) programmes were performed over targets
identified from geophysical interpretation. The results were
not encouraging and this licence will be relinquished.
Misungwi
The Misungwi licence covers an area of 25.38 km2 and is
underlain by Archean mafic volcanic rocks of the Lake Nyanza
subterrane. The licence is a dual gold-diamond target being
located within the Mabuki Kimberlite Province, adjacent to the
Shinyanga/Mwadui kimberlite province which hosts the Williamson (or Mwadui) diamond mine.
Exploration carried out in April 2013
was restricted to geological mapping and XRF analysis of shallow
soil samples. A total of 297 samples were collected from a
grid with a 400 m line and 200 m sample spacing. Laterally
extensive weak copper, lead and zinc anomalies were identified
which mimicked the outlines of flood plains of the rivers in the
area. Since these samples followed the course of the rivers
and were not coincident with structures identified with geophysical
features, it was decided not to submit the samples for gold
analysis. Subsequent work planned for the licence will investigate
the diamond potential by employing heavy mineral separation from
pit-dug samples.
Fort Ikoma
Reconnaissance mapping, lithogeochemistry sampling (48 samples) and
XRF multi-element shallow soil sampling (50 samples) was carried
out on the Fort Ikoma licence in March
2012. Results in this poorly exposed area were encouraging,
and it was recommended that a licence-wide shallow soil programme
be undertaken, with a higher density grid covering the Mugara
prospect. The Mugara prospect is a historic gold occurrence,
previously mined by artisanal miners, and appears from airborne
geophysics and mapping to be at the contact of a hydrothermally
altered mafic tuff and late granite. Field activities remain
suspended on the licence until government permits are issued
allowing work to be carried-out in the Ikorongo Game Reserve.
Siga
The Siga licence covers an area of approximately 51 km2
and is underlain by the Archean Siga Mabale Greenstone Belt and
associated granites. Much of the licence is covered by alluvial
deposits associated with Lake Nyanza, which obscures the surface
geology. The licence is located approximately 5 km south of the
colonial-period BIF-hosted Jubilee Reef or 'Augusta Victoria' gold
mine. Gold mineralization at the Jubilee Reef is recorded as being
associated by shear-zone hosted quartz veins, and recent
mineralization reported by Currie Rose Resources Inc. (TSXV: CUI)
at Masabi Hill includes 88 m @ 1.8 g/t Au from 114 m associated
with a granitic intrusion. Masabi Hill is located 6 km NW of the
Siga property. Masabi- and Jubilee Reef- style mineralization was
investigated in July 2013 through a
shallow soil geochemistry survey, which recorded 1,642 analyses
through the use of portable XRF equipment. An initial grid of
400 m wide lines and 250 m sample spacing was employed that
identified five areas containing anomalous concentrations of base
metals (Cu, Pb and Zn). Follow-up detailed grids (100 x 100
m) sampled over the anomalous areas and statistical analysis
resulted in the selection of 185 samples for gold assaying from two
of the areas. The two areas are 2 km x 1.5 km and 1 km x 1
km, with the larger area present at the contact of a late granitic
intrusion and mafic volcanic rocks. Gold assay results are
pending.
Haidom
The Haidom licence covers an area of 30.6 km2 and is
located on the eastern part of the Iramba Greenstone Belt.
Lithologies which underlie the licence include Archean
metasediments (micaeous phyllite), which have been intruded by
synorogenic granite and diabase dykes. Geophysical
interpretation and geological compilation was performed prior to
the start of the field programme in May. Geological mapping,
lithogeochemical sampling, extensive XRF soil geochemistry (1,095
samples) and follow-up gold soil geochemistry were all
conducted. The XRF soil geochemistry identified two areas
containing coincident copper, zinc and iron anomalies. A
total of 155 soils samples from three areas were assayed for gold,
with a maximum concentration of 11 ppb recorded. A total of 4
samples exceed the 90th percentile with gold
concentrations greater than 70 ppb. These samples were
collected from outcrops where the metasediments were cut by quartz
veins. Limited trenching over the elevated rock outcrops is
recommended.
Kiagata
Located within the Musoma-Mara Greenstone Belt, the 44
km2 Kiagata property is located approximately 5 km to
the north of the past-producing Buhemba mine (~ 0.7 Moz Au). High-resolution airborne
geophysics flown by the company in 2011 identified several
exploration targets on the licence, based on faults and splay
structures cutting the underlying granite and possible volcanic
units. A wide spaced 200 m by 200 m shallow soil XRF sampling
programme is currently being undertaken. Any base metal
anomalies located during this initial phase of the survey will
become the focus of a tighter (50 x 50 m) grid and gold soil
samples will be sent to the lab for assaying.
