      Bactech'S Strategic Partner Receives Permit To Evaluate The
      Lichkvaz-Tey Gold Deposit In Armenia
=======================================================================

Toronto, Canada, October 6, 2009 -- BacTech Mining Corporation
("BacTech" or the "Company", TSX.V: BM) announced today that it has
been advised by its Strategic Partner, Caldera Resources Inc.
("Caldera", TSX.V: CDR), that it has received permission from the
Ministry of Nature Protection of the Republic of Armenia, to conduct
geologic studies to evaluate the Lichkvaz-Tey refractory gold deposit,
located in Southern Armenia.

The Lichkvaz-Tey gold property has a Soviet-era GKZ mineral resource,
categorized as C1 and C2,  of 3.4 million tonnes grading on average 5.1
g/t Au, 33.2 g/t Ag and 0.41% Cu. This translates to approximately
575,000 oz of gold, 3.7 million oz of silver and 33.4 million pounds of
copper.

All numbers are historical and there is no NI 43-101 compliant report
prepared for this project. The data presented above was referenced from
the Mining-Metallurgical Institute of Armenia in 1986 Protocol GKZ USSR
N 10081 dd.28/11/1986. Caldera is in the process of obtaining these
historical reports so as to establish a sampling and exploration
program in order to create a NI 43-101 compliant report.  The
references to the GKZ mineral resource estimates appear in
independently prepared technical reports which are now in government
archives and were prepared for the former property owners. According to
the Committee for Mineral Reserves International Reporting Standards
(CRIRSCO), "C1" and "C2" classifications are equivalent to "indicated"
and "inferred" resources.

The property was explored during the Soviet era, resulting in 18 km of
drives and tunnels on 8 underground levels, spaced 40 m to 100 m apart
vertically and in numerous raises. The property is located 380 km south
of Yerevan, with access to power, water, a local workforce, and to the
main highway serving the area. 

The project is being pursued jointly with Caldera. BacTech has the
option to acquire a 40% interest in Caldera's subsidiary, Biomine LLC,
in return for providing technical support and test work for the
project.

Dr. Paul Miller, BacTech's Vice President of Technology and
Engineering, who reviewed internal data on the project, commented that,
"The project is a good candidate for bioleaching due to the refractory
nature of the ore and the strong interaction of arsenic with both base
metals and gold. The limited amount of diagnostic work suggests that
high gold extractions should be readily achievable if an oxidation
technique such as bioleaching were used prior to cyanidation for either
ore or concentrate treatment."

Caldera is assembling a geological team to retrieve samples from the
Lichkvaz-Tey deposit which will allow for the bioleach test work to
begin. BacTech will undertake bioleach test work at the University of
Toronto to confirm the recoveries when using bioleaching to liberate
the gold and copper associated with the deposit.

The option in the project held by BacTech will reside in BacTech's gold
subsidiary which will be spun out to the shareholders shortly, as
announced in a news release May 12, 2009.

About Armenia

Armenia sits in a geological formation know as the Tethyan Belt, which
contains some of the world's largest gold porphyry deposits. The
Tethyan Belt is a major porphyry-related mineralized zone that extends
across central and South-eastern Europe, Turkey, Armenia, Iran,
Pakistan, through the Himalayan region into Burma, Malaysia, Indonesia
and Papua New Guinea.

There are currently several mining companies extracting copper, zinc,
molybdenum and gold in Armenia. Dundee Precious Metals operates the
Kappan polymetalic mine, extracting zinc, copper, silver and gold. On
the exploration front, Lydian Resources is drilling a 1 million plus oz
gold resource in its Amulsar project.

About BacTech

BacTech Mining Corporation (TSX.V: BM) owns patented bacterial
oxidation technology for the treatment of refractory ores and
concentrates to enhance the recovery of gold, silver and base metals.
The Company's focus is the acquisition of equity positions in projects
amenable to bioleaching. In September 2008, BacTech signed an MOU to
investigate the use of bioleaching to reprocess arsenic-laden tailings
in Cobalt, Ontario. This is the Company's first foray into the
cleantech industry. BacTech is continuing to evaluate additional
remediation projects.

About Caldera

Caldera Resources Inc. (TSX.V: CDR) is focusing on projects amenable to
utilizing bioleaching or chloride leaching technology for the economic
recovery of base metals and precious metals from mine waste and
tailings, with a focus on Southeastern Europe and the Caucuses.

therefore the historical results should not be relied upon. Caldera and
BacTech believe these historical results provide an indication of the
potential of the properties and are relevant to ongoing evaluation of
the project.
