======================================================================

Toronto, Canada, October 16, 2007: BacTech Mining Corporation
("BacTech" or the "Company") resumed trading on the TSX Venture
Exchange (the "TSX-V") on October 4th after receiving approval from the
TSX-V. The stock had been halted on September 4, pending an
announcement of the Company's proposed acquisition of Scorpio Gold
Corporation ("Scorpio"). Full details are provided in news releases
dated September 6 and October 3, 2007.

The following is a summary of recent events involving BacTech and/or
Scorpio.

BacTech/Scorpio Merger - The proposed merger between BacTech and
Scorpio Gold is proceeding as planned, with a Definitive Agreement to
be signed shortly. BacTech will call a meeting of shareholders to vote
on the merger which constitutes a change of control of BacTech pursuant
to the policies of the TSX-V and, following conditional acceptance of
the merger transaction by the TSX-V, will deliver an Information
Circular to shareholders pursuant to which shareholders will be asked
to vote upon and approve the proposed merger transaction. BacTech has
secured expressions of support from over 40% of its shareholders.

Cochrane Hill, Nova Scotia - Scorpio's 60% joint venture partner on
this property, Atlantic Gold of Australia, issued a press release on
September 14th outlining an increase in grades at Cochrane Hill. Please
refer to Atlantic Gold's press release at www.atlanticgold.com.au to
view the details of the revised estimates. Atlantic is undertaking a
complete re-assessment of the historical core to better understand the
deposit, the results of which will determine a meaningful resource
estimate and follow-up drill program.

Golden China Resources Corporation - On August 7, 2007, BacTech and
Mintek of South Africa signed an agreement with Golden China to sell
their back in rights and a gold license to use BacTech's patented BACOX
technology in China, and North and South Korea. BacTech/Mintek received
847,000 shares of Golden China as compensation, with a deemed value of
$0.59 per share, or $500,000. On August 13, Golden China received a
friendly takeover offer from Sino Gold Mining Limited, an Australian
based company with extensive holdings in China. The offer contemplates
Sino issuing 1 share of their stock for every 4.5 shares of Golden
China, which will result in BacTech/Mintek receiving 188,000 shares of
Sino. Sino's stock recently has traded in the AUD$7-8 range, resulting
in a value of AUD$1.2M to $1.5M. BacTech will own 50% of the shares to
be issued by Sino.

2 Boys Uranium Property, Quebec -- Last month, the Company optioned a
uranium property located approximately 40 km north of Godbout, Quebec,
as announced in a news release on September 17. The $5,000 finder's
fee will now be paid to Exploration Esbec in cash, and not through the
issue of 25,000 common shares of BacTech as previously announced. The
property currently consists of 73 map designated claims covering an
area of 4,058 hectares; 50 claims are 100% owned by BacTech and 23
claims were optioned from local prospectors.

The Company has received a detailed report for the property that
outlines a two-phase work program. Phase 1 will include magnetic and
radiometric geophysical surveys and follow up sampling, and will begin
shortly. Phase 2 will be contingent on positive results from the
initial program.

BACTECH PROFILE

BacTech has developed and patented bacterial oxidation technology for
the treatment of refractory ores and concentrates to enhance the
recovery of gold, silver and base metals. BacTech has successfully
commissioned three bioleach plants for gold and demonstrated its
technology in the selective recovery of base metals from complex
sulphide concentrates in a joint project with Industrias Pe�oles de
C.V. of Mexico that was completed in 2001. The Company's focus is the
acquisition of equity positions in projects amenable to bioleaching.

The Company recently agreed to purchase the gold assets of TSX-listed
Scorpio Mining Corporation in exchange for common shares of BacTech,
which will result in Scorpio Mining becoming the controlling
shareholder of BacTech. It is expected, subject to the receipt of
BacTech shareholder approval, that the resulting company will be
renamed Scorpio Gold Corporation.
