Thorne Property (along Gold River Trend)
The Thorne Property was the largest land holding in West Timmins´ Timmins portfolio. The western continuation of the Destor-Porcupine fault system can be traced through the Thorne Property for over 7 kilometres.
The Golden River Deformation Zone is a 5.0 kilometre long trend of gold mineralization which parallels the Destor Porcupine and tracks through the Thorne Property. Discovered in 1996, the Golden River Trend hosts a National Instrument 43-101 compliant inferred gold resource of approximately 400,000 ounces and numerous other zones of gold mineralization which have been discovered since the last resource update in 1998. All zones remain open to depth and a number of untested geophysical anomalies indicate potentially to significantly expand the gold mineralized system along strike.
On February 10, 2010 the Company commenced drilling at the Thorne property. The majority of known mineralization defined to date on the property is related mainly to the Gold River East (North Porphyry and 4800 zones) and Gold River West areas where multiple lenses of higher grade mineralization occur in close proximity to each other. The 2010 drill program consists of approximately 20,000 metres and is being directed mainly towards extending the Gold River East and West areas to depth and along strike.
On May 4, 2010, initial results from the 2010 drill program were released and included extension of the North Porphyry Zone in the Gold River East area by 120 m to depth (to 520 m) and of the 4800 Zone by 125 m downplunge, as well as the reporting of multiple high-grade intercepts in the Gold River West area. The results highlighted the potential for significant resources at shallow depths with the possibility for open and/or underground bulk mining, as well as for deeper higher-grade resources with significant depth potential. (see May 4, 2010 press release)
On June 23, 2010, Lake Shore Gold announced results from an additional 17 holes (5,885 m) of the 2010 drill program at the 100% Thorne property. The results included significant extensions to mineralization in both the Fold Nose and North Porphyry zones in the Gold River East area with high grades and good widths. Both zones remain open along strike and at depth and include wide shallow mineralization with the possibility for open pit and/or underground bulk mining, as well as deeper higher-grade mineralization.
Among intersections reported on June 23, 2010 were: TH-10-21 which intersected 18.18 gpt over 11.00 m, including 33.54 gpt over 5.00 m, 2.68 gpt over 21.20 m and 5.32 gpt over 8.00 m within 75 m of surface, up plunge of previous drilling on Fold Nose target; TH-10-24 which intersected 13.19 gpt over 8.70 m, including 21.43 gpt over 4.20 m, 250 m below surface in Fold Nose target, 50 m down dip of previous drilling; and TH-10-26 which intersected 13.06 gpt over 8.50 m, including 295.00 gpt over 0.30 m, and extended the North Porphyry Zone in the Gold River East area by 150 m down dip to 650 m below surface.
The Qualified Person (“QP”) for Lake Shore Gold´s drill program at the Thorne Property is Jacques Samson, P.Geo. who, as QP, prepared or supervised the preparation of the scientific or technical information for the property and verified the data disclosed in the May 4, 2010 press release.

144 Project
The 144 Property covers the western extension of the Golden River Deformation Zone which hosts a number of zones of gold mineralization on the adjacent Thorne Property. Geologically, the 144 Property shares a number of similarities with the adjacent Thunder Creek and Timmins Mine properties, covering 4.0 kilometres of the same volcanic/ultramafic intrusive/sedimentary contacts found on these properties.
Recent drilling has intersected multiple zones of gold mineralization on the 144 Property located along this contact and associated with porphyritic intrusions which host some of the broadest and highest grade intercepts from the Rusk Zone at Thunder Creek.
The 144 Syenite discovery on the 144 Property, announced in February 2009, is hosted by a porphyritic intrusion located along the sediment-volcanic contact. With mineralized widths similar to those observed in the upper portion of the Rusk Zone, the 144 Syenite discovery has potential to be a significant gold zone. The 144 Property also hosts gold mineralization associated with quartz-carbonate vein systems within the mafic-ultramafic volcanic sequence which are typical of the majority of mineralization in the Camp and in association with disseminated sulphide zones within the sedimentary sequence.
