Lake Shore Gold Corp. (TSX:LSG) ("Lake Shore Gold" or the
"Company") today announced results from six new holes (1,233 metres) of underground drilling from the 730 Level
at Thunder Creek. The new holes were drilled from the face of the
access drift developed from the Timmins Mine on the 650 Level as well
as a cut out in the access drift located approximately 300 metres northeast of the Thunder Creek deposit which
includes the Rusk and Porphyry zones. The purpose of the diamond
drilling was to confirm the shape and grade of mineralization as
identified by previous drilling in support of exploration development
within the zones. This exploration development will include strike
drifts and cross cuts for the purpose of mapping, sampling and
metallurgical testing to help characterize the mineralization.
Five of the holes, TC730-001, 730-002, 730-003, 730-004 and 730-006,
were drilled from the face of the access drift at the 730 Level. Among
results reported were 26.25 gpt over 28.90m,
including 35.80 gpt over 20.90m and 105.67 gpt over 6.00m, in TC730-003; 12.11 gpt over 35.20m, including 18.67 gpt over 19.85m, and 14.38 gpt
over 38.80m, including 20.22 gpt over 14.80m,
in TC730-004; 3.98 gpt over 46.40m and 6.64 gpt over 13.50m, including 10.44 gpt over 7.70m in TC730-002; 3.53 gpt over 105.00m in TC730-001 and 1.81 gpt over 91.80m in TC730-006. The holes intersect
the Rusk and Porphyry zones at a variety of angles and strongly confirm
a broad mineralized zone containing substantial widths and grades.
In addition, one hole, 650-005, intersected 8.60 gpt
over 29.70m, including 13.01 gpt over 11.00m, defining a western extension of
the Rusk Zone on the 730 level.
Tony Makuch, President and CEO of Lake Shore
Gold, commented: "Today's results are the latest drill holes from
the planned 2011 underground drill program at Thunder Creek. The
program is aimed at characterizing and expanding the shapes of
mineralization both within the Porphyry and Rusk zones as we work
towards establishing an initial National Instrument 43-101 resource by
the second half of the year. These results demonstrate that, in
addition to the potential for large-scale, low-grade bulk mining, there
exist multiple areas of thick, high-grade mineralization within the
broader Porphyry and Rusk zones."
Based on the new results, the Rusk and Porphyry zones form a continuous
broad envelope measuring approximately 175 metres
long by as much as 100 metres wide at the 730
Level at Thunder Creek. The envelope covers the full width of the
TC-144 alteration zone with an overall dip of approximately 65 degrees
to the north. The TC-144 alteration zone is interpreted as a major
structure that extends approximately six kilometres
in a southwesterly direction from the Timmins Mine through Thunder
Creek and the 144 project towards the Destor-Porcupine
Fault Zone (DPFZ). The alteration zone has the potential to host
significant gold mineralization at multiple locations. Both the Rusk
and Porphyry zones are open along strike and dip. Observations of the
Porphyry Zone in the 730 Level exploration drift and in drill core
indicate that the mineralization is characterized by swarms of quartz
veining with increased pyrite and local visible gold.
Results from two additional holes, which were also drilled from the
face of the access drift (TC730-004B and TC650-005), are still pending.
Drilling is continuing with two drills working on several additional
holes from the face of the access drift. Work is also advancing to
develop two new hangingwall drifts which will
support additional detailed diamond drilling of the zones from the 600 metre level to the 1,500 metre
The Company's Qualified Person ("QP") for the underground
drilling being completed on the Thunder Creek property is Dean Crick,
P. Geo. As QP, he has prepared or supervised the preparation of the
scientific or technical information and has verified the data disclosed
in this press release. Mr. Crick is an employee of Lake Shore Gold.
Lake Shore Gold has a quality control program to ensure best practices
in the sampling and analysis of all drill core.
Assays have been completed at both ALS Chemex
(TC200 series holes) and LSG - Bell Creek lab (TC300 series holes);
both labs use a standard fire assay with a 30-gram aliquot. For samples
that return a value greater than 10 grams (ALS Chemex)
and 20 grams (Bell Creek) per tonne gold,
another pulp is taken and fire assayed with a gravimetric finish.
Mineralized sections of the Porphyry Zone are analyzed using the "metallics" or screen fire assay technique.
BQTK 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
to either the Bell Creek lab for preparation and analysis or to the ALS
Chemex Prep Lab located in Timmins, Ontario.
The pulps from core that is sent to the ALS Chemex
Prep Lab are then shipped to ALS Chemex Assay
Laboratory in Vancouver, BC. ALS Chemex is an
ISO 9001-2000 registered laboratory preparing for ISO 17025
certification. The LSG - Bell Creek lab conducts in-house analysis of
mill, underground and drill core samples and is not an ISO 9001-2000
