Lake Shore Gold Reports Results of Underground Drilling and Development at Timmins Mine, Results Confirm Previous

TORONTO, ONTARIO, Oct 29 (MARKET WIRE) --
Lake Shore Gold Corp. (TSX: LSG) ("Lake Shore Gold" or the "Company")
today announced encouraging results from 21 underground holes (4,417 m)
from the 525 m and 650 m Levels of the Company's 100% owned Timmins Mine
Property. The holes represent the continuation of an ongoing drilling and
bulk sampling program which is testing the continuity and grade of the
Ultramafic ("UM") Zone and Footwall Zone between the 650 m and 525 m
Levels. Current drilling from 650 m Level is being done on 12.5 m centres
and targeting a 50 m horizontal slice above the 650 m Level which will be
part of the first test stope.

Key intercepts from the 21 holes include: 16.41 gpt over 14.20 m
(including 114.00 gpt over 0.70 m) and 13.26 gpt over 12.70 m (including
63.37 gpt over 1.20 m) and 52.89 gpt over 5.75 m. Holes drilled
intersected grades and widths consistent with previous surface drilling,
with the overall size and shape of the main Ultramafic Zone ("UM1") being
shown to be similar to previous projections, based on current drilling.
In addition, Hole 525-005 intersected high-grade mineralization in areas
outside of the existing resource at the 525 Level, including grades of
7.19 gpt over 14.15 m and 4.99 gpt over 15.50 m. New high-grade lenses
were identified on the 650 m Level between the Ultramafic and Footwall
zones, including 10.79 gpt over 4.10 m in Hole 650-023 and 14.67 gpt over
3.75 m in Hole 650-025a.

New modeling and resource estimation for the 50 m horizontal slice above
the 650 Level being evaluated, using inverse distance squared block
modeling and a 50 gpt capping factor, suggests that tonnage and ounces
for the Utramafic Zone resource could be expanded from the most recent
43-101 resource calculation at similar grades.

Tony Makuch, President and CEO of Lake Shore Gold, commented: "The
results from our ongoing underground drilling and development program at
Timmins Mine are very encouraging and confirm the grades and widths
established from previous surface drill programs. With the results from
holes 525-005, 650-023 and 650-025a we also continue to intersect
high-grade mineralization outside of the known resource. Our development
from the shaft on the 650 m Level is also advancing very well and we have
commenced driving a development ramp 20 m above the 650 Level where we
are planning our first sublevel."

Mineralization in the area being evaluated occurs as a series of E-W
trending lenses surrounding a steep west plunging fold nose formed at the
contact between ultramafic and volcanic rocks. The bulk of known
resources are contained within the UM1 Zone, which occupies the core of
the fold, and Footwall Zone to the north and along the contact of the
Ultramafics with volcanic rocks. The UM1 Zone has an average strike
length of approximately 125 m and width of 10 to 15 m. The Footwall zones
are shorter in strike length but may be more numerous than originally
thought and have local high grades.

Closely associated with the mineralization in the Ultramafic and Footwall
zones is quartz veining, abundant pyrite, strong alteration, and local
visible gold Besides confirming grades obtained by previous surface
drilling, mineralized intercepts in this recently completed underground
diamond drilling correlate well with the predicted locations of the zones
as interpreted from the original more widely spaced surface drill holes.

At present 54 holes and 8,144 m of diamond drilling have been completed
on the 650 level with 32 holes and 3,596 m remaining to be reported. An
additional 28 holes (6,012 m) have been drilled on the 525 m Level with
results for three holes being reported to date. Based on positive results
so far a development ramp is now in progress to access the area approx 20
m above the 650 m Level where ore definition for the first mining block
and bulk sampling will continue.

Quality Control

The Company's Qualified Person ("QP") for the underground drill program
at the Timmins Mine property is Heather Miree, P.Geo. As QP, she has
prepared or supervised the preparation of the scientific or technical
information for the property and has verified the data disclosed in this
press release.

Lake Shore Gold has implemented a quality-control program to ensure best
practice in the sampling and analysis of the drill core. Samples are
obtained from BQTK-sized diamond drill core, with roughly 75% of sampled
core being sawn in half and the remaining 25% being whole core sampled.
All remaining core materials, including the remaining half of sawn core
is retained on site in a secure location. Drill core samples are s for
sample preparation and gold analysis performed by ALS Chemex. ALS Chemex
is an ISO 9001-200 registered laboratory, preparing for ISO 17025
certification. Drill core samples are transported in security-sealed bags
to ALS Chemex's Timmins Sample Preparation Facility. Sample preparation
is completed in Timmins, and the prepared sample pulps are then
transported to ALS Chemex's analytical laboratory in Vancouver, BC. Gold
grades are obtained on all samples via Fire Assay with Atomic Absorption
finish, using 50g aliquots. For samples that return a gold content
greater than 3 gpt, the sample is reanalyzed via Fire Assay with
Gravimetric finish, again using a 50g aliquot.

About Lake Shore Gold

Lake Shore Gold is a mineral development and exploration company that is
moving towards gold production through its 100%-owned Timmins Mine
project, where the Company is sinking a shaft and driving a ramp. The
wholly owned Bell Creek Mill, located on the east side of Timmins, has
been refurbished to a capacity of 1,500 tonnes per day. The Company is
also making progress with an underground advanced exploration program at
its Bell Creek Complex, including the Bell Creek Mine, Schumacher and
Vogel properties, which have the potential to become the Company's second
mining project in the Timmins Camp. In addition, Lake Shore Gold is
pursuing a number of other highly prospective exploration properties in
Northern Ontario and Quebec. The Company's common shares trade on the TSX
under the symbol LSG.

On August 27, 2009, Lake Shore Gold and West Timmins Mining Inc. ("West
Timmins") announced an agreement for a business combination under which
Lake Shore Gold would acquire all outstanding West Timmins common shares
at an exchange ratio of 0.73 of a Lake Shore Gold share for every West
Timmins common share. As a result of the proposed transaction, Lake Shore
Gold would acquire the 40% of Thunder Creek not currently owned and
approximately 120 square kilometers of highly prospective property in
close proximity to Thunder Creek, as well as a significant land position
in Mexico. Subject to the approval of West Timmins shareholders and the
satisfaction of other conditions, the transaction is expected to close in
November.
