Copper mining in Lausitz will not start before 2020

The copper mining in the Lausitz will start later than previously
thought. Experts of mining companies and Mining Authority told at a
briefing in Krauschwitz that is not the first ore can be recovered
before 2020. It was originally planned to start early as 2015 with the
promotion. Before about 60 interested people, mainly residents of the
affected region, said the experts how it goes with the copper mining
industry in the coming years.

Copper mining in Lusatia

The rights for the reduction of copper ore in the Lausitz region
shared by two companies. White water companies around the copper shale
Lausitz, KSL, is currently investigating the area. CEO Thomas stated
in Lautsch Krauschwitz the construction of the mine in 2014 at the
earliest in view. This would last for six years. Whether the mine can
be built at all, 2013 will be decided. Spokeswoman Pia Verheyen said
the MDR, recently lay before the results of seismic exploration. This
could be derived, where the best location for the mine and mining
methods, which are due to the structures in the ground at all in
question. The results are according to Verheyen now in the planning
for the construction of the mine. Only when it is unclear how the ore
can be mined economically, and whether the security is ensured that
the mine would be built.
Initial drilling at White Water

In addition to the KSL is also the Polish company KGHM, while, in the
Lausitz to drill for copper. He was awarded exploration rights in the
area around white water. KGHM expected to be later than the start of
the KSL copper production. In July of this year saw the first test
drilling. KGHM has been in more than 50 years experience of copper
mining. The company is also one of the world's largest silver
companies.

Actually, should at the event in Saxony Finance Minister Georg Unland
Krauschwitz also occur, and on copper mining in Lausitz lecture. But
he had previously suffered from a panel in white water, a faint and
was taken to hospital.
Copper: Valuable Treasure of the Lausitz

Stored in the Lausitz valuable copper shale. There are currently
drilling to explore how rich are the deposits. It is still unclear
whether the copper is mined.

Health of workers in gold mines should be improved

- children are exposed to high risk of poisoning

Nairob - Governments around the world protect the health of millions
of prospectors who work with mercury, the human rights organization
Human Rights Watch. Prior to the negotiation of an international,
legally binding agreement on mercury, Human Rights Watch uses with
recommendations to the participating governments. In around 70
countries worldwide small-scale mining is operated, which is often
referred to as "the mining of the little man." The workers use
labor-intensive, technically simple methods. In order to extract gold
from raw ores, they use the cheap and easy to handle mercury. The
highly toxic heavy metal, however, takes on the central nervous system
and is particularly damaging for children. According to doctors, high
mercury exposure affect the development of the brain, kidneys and
digestive system and cause developmental problems. The small miners
come in contact with the heavy metal when they mix raw ore and mercury
with bare hands and - far worse - the burning of the amalgam to
separate the gold inhale toxic fumes.

"Efforts to reduce mercury use in gold mining are important. In the
debate, however, lacks an approach that puts the public health care
for the miners in the forefront, "said Juliane Kippenberg, children's
rights researcher at Human Rights Watch. "The agreement should mercury
be treated not only as a technical and environmental issue, but also
the right to adequate health care are addressed."

The negotiations will be presented at the Third Session of the
Intergovernmental Negotiating Committee of 31 October to 4 November
2011 held under the leadership of the UN Environment Programme in
Nairobi, Kenya.

Mine work is among the world's most dangerous professions.
Nevertheless, work according to the International Labour Organization
in Asia, Latin America and Africa about a million children in the
small-scale mining to reduce gold - some of them already from the age
of six years. Human Rights Watch has documented how children in Papua
New Guinea, Mali and Nigeria exposed to mercury.

A 11-year-old girl from Mali told Human Rights Watch:

"Once the ore is washed, you do this a little mercury. You rub the
brass, and the mercury with both hands. Then, when the mercury has
attracted the gold, you do it in a metal box and burn it. When I'm
done, I'll sell the gold to a dealer. I do it every day ... I know
that mercury is dangerous, but I do not know how. I do not protect me.
"

Children, including infants come into contact with mercury when their
mothers take them to work in the gold mines and burn amalgam in their
immediate vicinity. Mercury can enter the mother's milk in the bodies
of infants and fetuses at risk even in the womb when their mothers are
working with the heavy metal.

Under international law, governments must prevent children working
with mercury. Working with mercury is considered as one of the worst
forms of child labor. International law also requires governments to
reduce the risk of environmental toxins, such as a reduction or a
prohibition of contact with harmful substances.

Currently there is no simple alternative to the use of mercury for
miners, which promote small scale mining in gold. Nevertheless, the
required amounts could be drastically reduced and the effects are much
better controlled. Mine workers should use special containers
("retorts") that capture the mercury vapor. Particularly harmful
practices, such as the use of mercury in residential areas should be
prevented. Industrial gold mines use expensive, complex techniques,
using mercury instead of cyanide.

In its recommendations, Human Rights Watch said that the contract will
oblige governments to adopt national action plans to reduce mercury
use in gold mining. These should include the following measures:

The health of vulnerable groups, particularly children, should be
improved. These are tests and treatments for those who are already
compromised by the use of mercury, and include the collection of
health data, training of medical staff and education about the dangers
of mercury by health centers.

Strategies should be developed within a specified time frame, through
the use of mercury by children and pregnant women are prevented in
small mines. These are educational measures, the enforcement of laws
against child labor, and include programs must work with the children
no longer in the small-scale mining.

It would be set concrete targets for reducing mercury use for the next
five, ten or 20 years.

"Governments have done far too little to protect children from mercury
and to end child labor in small-scale mining," said Kippenberg. "With
this contract, they can prevent hundreds of thousands of children are
exposed to mercury and poisoned."

tantalum and niobium mining methods and feasibility study

Commerce Resources Corp. .. gives positive preliminary economic
assessment for the Upper Fir tantalum and niobium deposit in Blue
River, British Columbia, known

DGAP-News: Commerce Resources Corp. .. / Key word (s): Between
Commerce Resources Corp.. report. gives positive preliminary economic
assessment for the Upper Fir tantalum and niobium deposit in Blue
River, British Columbia, known

The main points

- AMECs PEA technical report on the tantalum-niobium project in Blue
River, dated the 29th September 2011, will be published shortly
- The results of the study show a positive cash flow for a possible
underground operation (7,500 tons per day) to Upper Fir at Cash Costs
of 24.91 CAD per kg of tantalum metal (minus the Niobmetallguthaben)
in the form of an oxide product of technical quality.

- AMECs economic evaluation based on the mineral resource of 36.4
million tonnes of indicated mineral resources of 195 ppm (g / t) Ta2O5
and 1.700 ppm (g / t) Nb2O5 and 6.4 million tonnes of inferred
resources of 199 ppm (g / t) Ta2O5 and 1890 ppm (g / t) Nb2O5.

- The PEA (Preliminary Economic Assessment, preliminary economic
assessment) identified opportunities for the optimization of geology
and mining areas, where the key risks lie for project development in
the susceptibility of the project to fluctuations in commodity prices
and the exchange rate of U.S. dollar against the Canadian dollar.

- After completion of the PEA AMEC has now begun work on an updated
mineral resource estimate, the results of the drilled holes and the
end of 2010 to 29 September 2011 include assay results received will
be. This is followed by a technical report of the holes, analysis,
geological mapping and other work is included, Which were carried out
on Upper Fir to the end of Commerce's 2010 field program. A subsequent
update of this technical report is also planned. It will include the
results of drilling conducted in 2011 and metallurgical test programs.

- The results of the PEA are forward-looking information. The
preliminary economic assessment is only preliminary in its nature and
includes inferred mineral resources, one that will be considered on
the basis of geology as too speculative to be considered as
economically, Which would make it into the category of mineral
reserves. Furthermore, it is uncertain Whether the preliminary
economic assessment will be implemented. Mineral resources are not
mineral reserves, because they have not Demonstrated economic
viability.

Vancouver, British Columbia. Third November 2011. Commerce Resources
Corp. .. (TSX: A0J2Q3 TSX-V: CCE; OTCQX: CMRZF) announces the
completion of a positive, with National Instrument 43-101 compliant
Preliminary Economic Assessment (Preliminary Economic Assessment,
"PEA") for the Upper Fir tantalum and niobium deposit in Blue River
British Columbia announced. The PEA, Which was by the independent
consulting firm AMEC Americas Limited ('AMEC') were made, indicates
that the deposit can be economically developed as in underground mine
and Proposes to support a feasibility study for the project for
further studies. The Blue River Project is located near the town of
Blue River, about 250 km north of Kamloops and 90 km south of the town
of Valemount.

The project PEA was prepared to delineate the concept of fitness for a
further development of the Blue River. It includes geological models
and mineral resource models, the preliminary mine planning, a
description of the metallurgical test work and preparation of plans, a
summary of the basic work environment to date and estimates of capital
and operating costs. It also plans to deterministic mines the
profitability of a development project as in underground mine with
processing. An estimate of the direct cash costs for the preparation
of tantalum oxide product in the form of a technical grade is also
included. Readers are encouraged to read the entire PEA technical
report, Which is under. On the website of the company also find a
link.

The main findings of the PEA

- An indicated mineral resource of 36.35 million tonnes at 195 ppm and
1.700 ppm Nb2O5, Ta2O5 and 6.4 million tonnes of Inferred Mineral
Resources of 199 ppm and 1890 ppm Nb2O5, Ta2O5 (see press release
dated February 2, 2011). - Underground mining of 7.500 tons per day,
using different variants of the Chamber building piers. - Estimated
production of 2.7 million tonnes of ore over 10 years. - Mineral

ferro-columbite and pyrochlore. - The end products of tantalum and
niobium oxides will be, a total of 2.400 metric tons and 18 610 metric
tons of these metals during the life of the mine. - The total
estimated capital cost for the design and construction are at 379
million CAD. - The operating costs over the life of the mine are
estimated at 38.44 CAD per tonne milled. - Before tax is the Net
Present Value (NPV, net present value) of the project with interest a
factor of 8% at 18.5 million CAD with an internal rate of return of
9.1%. The amortization period would amount to 6.3 years when using an
internal rate of return method. - Cash Costs kg for tantalum metal

Property

The Blue River Project covers on area of ​​105 373 hectares (1,000
km2) off high voltage power lines, railroads and paved roads and
unpaved run close to or within the property boundaries. The Bone Creek
18 MW hydroelectric power project is under construction near the
project and was put into operation in June 2011th

Resource Estimate

The resource comprises a series of seam shaped carbonatite bodies with
up to 91.2 m in estimated true thickness. This composite body covers
more than 1450 m in a north-south direction and up to 800 m on
east-west direction. Tantalum and niobium are present in the minerals
pyrochlore and columbite-Ferro.

The PEA was based on a mineral resource estimate, Which was published
in February 2011 ("Blue River Ta-Nb Project NI 43-101 Technical
Report, Blue River, British Columbia 'by AMEC, January 31, 2011). AMEC
used the drilling of boreholes drilled by the end of 2009. This
included 183 bores, Which provided for the creation of the resource
estimate of 37 446 m HQ core samples and drill core samples were sawn
from 8218th Most holes located at a nominal spacing of 50 m with
slopes that were typically between -60 degrees and subvertical
orientation. The results of the holes drilled in 2010 were compared
with the existing resource model and it was found that they to some
extent with the model predicted geology in agreement. Likewise, the
preliminary drilling results from the year 2011 were examined on site.
It also turned out that they also coincide with the geological model
predicted.

The new expiration date for the resource estimate, based on a review
of current drilling is now the 29th September 2011 (Table 1). There
was no amendment to the final date of data collection, Which was used
to estimate and includes all the holes that were drilled by the end of
December 2009.

Table 1: Blue River Project Estimated resources.

(More tables in the original press release available on the website of
the company -

The following Table 2 shows the coupling of the Blue River tantalum
resource with the price

Table 2: Blue River project linking the estimated resources with the
tantalum price:

AMEC is of the view that the preferred approach for reducing the Blue
River reservoir is an underground mining chamber with different
variants of the pillars of building a conceptual scenario assuming
that the extraction and processing of 7.500 tons per day included.
Access to the deposit is made by two mine shafts in places where the
deposit occurs at the slope edge-to-light. They will be about 4 km
from the proposed location of the treatment plant. The excavated
material by the above procedure Corresponds to 84% of the resource. A
further 2% were identified as internal ore overburden thinning.
Geotechnical Studies Indicate that a recovery rate of 67.5% can be
achieved. This results in at overall yield of 58%. Taking into account
the waste rock in the tunnel and external dilution, the resource
estimates of funding levels for the ore to a total of 185 ppm and 1591
ppm Nb2O5, Ta2O5 have been reduced.

Based on experience with relevant AMECs deposits and mining methods,
mining and economic parameters were adjusted. There is a processing
method that will use a standard-grind flotation process to produce a
concentrate of ferro-columbite and pyrochlore, provided for the Upper
Fir ore. The proposed processing method is similar to the one used in
the Niobec mine from Iamgold Commercially applied in Quebec. The
concentrate will be further processed to produce marketable separate
niobium and tantalum. The proposed processes are mature and already in
industrial use.

End products and base case metal price fixing

The proposed processes for the Blue River Project will produce 99.9%
pure tantalum and niobium oxides, commonly known as the oxide product
of technical quality. These products are usually sold under contract
and the prices are between the buyer and seller kept confidential to
maintain the competitive edge.

Tantalum

Tantalum is usually given in two separate forms:

* Ta2O5 in Tantalitkonzentrat: an uncoated, tantalum-containing
concentrate of variable composition and content of trace elements, and
* tantalum scrap (99.9% pure Ta), tantalum this product provides a
supplement to the market Relatively Tantalitkonzentrat

In the past six years, moved the Tantalitkonzentratpreise between 75
USD / kg contained Ta2O5 and 110 USD / kg contained Ta2O5 (34 USD / lb
- 45 USD / lb). In the same period, the tantalum scrap metal prices
ranged from 110 USD / kg Ta up to 180 USD / kg tantalum metal (50 USD
/ lb - 82USD/lb).

2010, the prices because of numerous conditions, including reduced
production, increasing concerns about production of tantalum conflict
in Africa, the depletion of known strategic stockpiles have risen
dramatically. In mid-October 2010, the price for Ta2O5 in tantalum
concentrate at 195 USD / kg (89 USD / lb) and tantalum scrap metal at
280 USD / kg (127 USD / lb).

The higher price for tantalum scrap metal compared to the price of
Ta2O5 in concentrate is to be regarded as a proxy for the additional
value that should be realized through the refinement of Commerce Blue
River concentrate to high purity Ta2O5.

Niobium

Niobium is usually as niobium metal and ferro-alloy. The price was
relatively stable in recent years at $ 44.08 / kg (20 USD / lb). It
was assumed a base case price of 46 USD / kg (21 USD / lb) for niobium
metal.

PEA price assumptions

The metal price assumptions that were used to Determine the cut-off
and reduce the financial analysis in the PEA are 317 USD / kg for
tantalum metal and 46 USD / kg for niobium metal oxide product.

Comments of the Commerce president

'We are with the results of this study, a major milestone Which is
progress in the development of Upper Fir, very satisfied. The AMEC PEA
is released today, is a further confirmation of Commerce's view that
we are currently developing a very important, long-term source of
conflict-free and morally justifiable tantalum, Which could cover
almost 10% of global demand over almost 10 years, "said Dave Hodge,
Commerce's president. 'The results of the additional wells that were
drilled in 2011 are closed pending and we are eagerly awaiting the
results of AMECs Ressourcenaktuaslisierung next, based on the end of
the 2010 field season will be holes drilled. Everything indicates that
we can improve the quality of the resource even further. '

'Of necessity, the resource estimate was based, the PEA was used as
the basis of an assumed long term price fixing, Which could prove
conservative. The recent developments in global tantalum and
Niobmärkten Provide an indication of much higher prices than those
that were used to define the resource on Which the PEA is based. For
example, enter information for the 30th Asian Metals September 2011
(CAD = 0.961429 USD) for Nb2O5 (99.5%) with average quality of a price
61-66 USD / kg, and Ta2O5 (99.95%) with average quality of a 378 price
-403 USD kg / in. Search prices could offer to opportunity for ongoing
resource upgrade, they aim at Achieving higher prices, but
conservative. We believe that there will be a positive development in
the foreseeable future for investors who believe that the projected
trends will continue for higher prices. '
