  *  TC09-68b intersects 12.75 grams per tonne (gpt) gold (Au) over 83.40 metres 
  (m), or 13.73 gpt over 77.50 m, including 24.68 gpt over 13.00 m, 38.22 gpt over 
  11.00m and     26.78 gpt over 8.50m 
  *  High-grade intercepts among best drilled in Timmins Gold Camp 
  *  Second mineralized porphyry unit identified 
 
 
 
Hochschild Mining plc ("Hochschild") is pleased to announce that Lake Shore 
Gold, in which it has a 40% investment, today announced results for six new 
holes and one wedge hole (5,900 metres) as part of its ongoing 22,000 metre 
diamond drill program at the Thunder Creek joint venture property, located 
immediately adjacent to Lake Shore Gold's 100%-owned Timmins Mine project. Lake 
Shore Gold holds a 60% interest in the Thunder Creek property, and is the 
operator of the joint venture with West Timmins Mining Inc. 
 
 
Miguel Aramburú, Chief Executive Officer of Hochschild Mining plc, commented: 
 
"We are delighted with the encouraging drill results reported by Lake Shore 
Gold, in which we have a 40% interest. Lake Shore Gold is a long term strategic 
asset for Hochschild and we remain extremely confident about the company's 
prospects. We are working closely with their management team to continue to 
explore the full potential of their assets." 
 
 
Tony Makuch, President and CEO of Lake Shore Gold, commented: 
 
 
"The widths and grades of the intercepts reported from wedge Hole TC09-68b are 
clearly our most encouraging to date and demonstrate that we are dealing with a 
large gold system. The results highlight the potential of Thunder Creek to host 
a significant orebody with multiple horizons covering different geological 
settings, including the Rusk and Porphyry zones, as well as a new porphyry unit 
that has now been discovered at the bottom of TC09-68b. We are currently 
awaiting results from one wedge hole with four additional holes in progress. We 
have a total of four drills operating on the property, with approximately 
15,000 metres of the current 22,000 metre drill program having now been 
reported. We have also added a drill on our 100% owned Timmins Mine property to 
explore for new mineralization along the north-east extension of the same 
geological contact hosting the Rusk Zone." 
 
 
The results include wedge Hole TC09-68b, which intersected the best widths and 
grades encountered to date at Thunder Creek. TC09-68b intercepted 12.75 gpt Au 
over 83.40 m or 13.73 gpt over 77.50m, including 24.68 gpt over 13.00 m, 38.22 
gpt over 11.00 m and 26.78 gpt over 8.50 m. The broad intercept in TC09-68b, 
which spans the full width of the Porphyry unit, contains many of the 
features from other holes including strong alteration, intermittent quartz 
veinlets, local visible gold and accessory minerals such as molybdenite, galena, 
sphalerite and scheelite. TC09-68b also intersected mineralization in the Rusk 
Zone, with an intercept of 5.62 gpt Au over 4.90 m, including 9.50 gpt over 2.20 
m, and also intercepted 1.01 gpt Au over 6.00 m in a new, second Porphyry unit 
discovered near the bottom of the hole. TC09-68b is located approximately 50 
metres above the previously released wedge Hole TC09-68a, which included an 
intercept of 10.09 gpt Au over 4.70 m, including 17.16 gpt over 
2.25 m. 
 
 
Hole TC09-72 was an infill hole designed to test for the upper limits of the 
Rusk and Porphyry zones. 
The Rusk Zone was weakly mineralized, whereas the Porphyry Zone was intersected 
with local occurrences of visible gold. The results of TC09-72 confirm the down 
dip extension of the Porphyry Zone. 
 
In addition to wedge Hole TC09-68b and Hole TC09-72, Lake Shore Gold also 
released results for Holes TC08-63, TC08-65, TC08-66, TC08-67 and TC09-71. 
TC08-63 and TC08-65 were drilled to test a large Syenite intrusive located 400 
to 500 metres south of the Rusk Zone and intersected local strongalteration and 
low grade gold values, which could form an important new target for future 
exploration. Holes TC08-66 and -67 were preliminary holes drilled to the 
north-east of the known mineralized systems, with Hole TC09-71 located 125 
metres south-west of Hole TC09-69 and representing the first attempt to expand 
the zone southwards at this elevation. Hole TC09-71 encountered multiple 
intrusions of Porphyry and local strong alteration surrounding these and the 
Rusk Zone suggesting that the mineralized system is still open in this 
direction.

Lake Shore Gold's Qualified Person ("QP") for the Thunder Creek property is 
Jacques Samson, P. Geo. As QP, he 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 a quality control program to ensure best practices in the 
sampling and analysis of drill core. Assays have been completed using a standard 
fire assay with a 30-gram aliquot. For samples that return a value greater than 
three grams per tonne gold, another pulp is taken and fire assayed with a 
gravimetric finish. Zones with visible gold are tested by pulp metallic 
analysis. NQ size drill core is saw cut and half the drill core is sampled in 
standard intervals. The remaining half of the core is stored in a secure 
location. The drill core is transported in security-sealed bags for preparation 
at ALS Chemex Prep Lab located in Timmins, Ontario, and the pulps shipped to ALS 
Chemex Assay Laboratory in Vancouver, B.C. ALS Chemex is an ISO 9001-2000 
registered laboratory preparing for ISO 17025 certification.
