Weststar Resources Corp., subject to regulatory approval, has entered into a letter of intent with a group of arm's-length vendors, pursuant to which the company has acquired 72 coal permit applications, known as the "18 Meter" property, located approximately 120 kilometres northwest of the recent coal discovery of Goldsource Mines Inc.'s coal discovery, near the community of Hudson Bay, Sask. The coal lease applications encompass approximately 138,240 acres or 55,944 hectares. The coal lease applications have been granted priority status by the Saskatchewan ministry.

The Tobin Lake property is located 50 kilometers from the community of Nipawin, central Saskatchewan.
Geological Summary for Weststar:
The Weststar Tobin Lake property lies within Central Saskatchewan, proximal to the sedimentary edge of the Western Canada Sedimentary Basin. The property sits on top of the Mannville Group, with the underlying Devonian carbonate Ashern Formation to the Northeast and the overlying Cretaceous Lower Colorado Group to the Southwest.
The Mannville Group is a primarily non-marine sandstone and shale unit, early Cretaceous in age. The Lower Mannville consists of non-marine clastic sedimentation shed as alluvial plains and deltaic deposits sourced from and due to the mountain building to the west. This allowed for peat accumulation, which gave rise to the development of extensive coal seams. The Upper Mannville was deposited primarily as continental to transitional marine sediments during the withdrawal of the inland sea. This again allowed for great amounts of peat accumulation leading to numerous coal beds being deposited, with individual beds reaching 4.5 m in thickness, or greater and cumulative thicknesses upwards to over 12 m. (Coal Resources of Canada, 1989)
There have been historically identified showing of coal Saskatchewan within the Lower Cretaceous stratigraphy. Examples of these showings include:
- Most recently, Goldsource Mines Inc. discovered coal thicknesses between 27-34m within the Mannville Group, 120 kilometers southwest of the Tobin Lake property.
- In recent discoveries, Consolidated Pine Channel Gold Corp. completed an exploration program in 1994 discovering the "18-meter hole", which lies on the Tobin Lake property. This coal began at a depth of 47.7 m and contained 7.6 m of massive coal followed by 11.22 m of coal breccia, containing up to 60 per cent coal clasts. The discovery was made while testing a magnetic geophysical anomaly for kimberlite. The historical drill log (TL02-2, assessment report 63E-0004) indicates:
- 47.70 meters to 55.32 meters (7.62 meters): coal, massive;
- 55.32 meters to 66.54 meters (11.22 meters): coal breccia, from 20 to 60 per cent angular coal clasts, mixed with varying amounts of clay, silt and sand.
- In the 1970's Flin Flon Mines Ltd and Brascon Resources Ltd explored the area south of Lac La Ronge, which lead to the discovery of the Bow River Coal Field. The companies defined a non-43-101 compliant 50 million t resource, where the sub-bituminous coal in seams that average a net thickness is 1.8 meters, and buried beneath an average of 25 meters overburden. This deposit is 170 kilometers northwest of the Tobin Lake Property
- In the 1980's Luscar Ltd. examined more than 400 electric drill logs in the west-central area of Saskatchewan, where they defined 1.7 billion t of sub-bituminous rank coal in seams that average a net thickness of 2 meters. This resource of coal is hosted by the Manville Formation where is dips to 830 meters below the surface.
- Coal outcrops were recorded in 1921 in the Wapawekka Lake area (east of Lac La Ronge), where coal seams up to 1.6 meters were recorded in test pits.
