1945: Mr. J.M. Thrasher was seeking fluorite at this location and found economical gold instead. (Kenora AF 52F/05NW, H-1, Thrasher Claims) Previous Work Work on the property dates back to the mid 1940's when the ODM inspected fluorite +/- gold showings staked by J.M. Thrasher. 1964 D.V. Reade trenched and drilled six x-ray holes into the fluorite showings to assess their potential. Activity resumed in the early 1980's when Bob lFairservice recognized additional gold potential in the area and staked and optioned the property. Several groups have explored the property more recently including: 1983 Esso Minerals Canada conducted geological mapping, stripping, trenching and channel sampling with limited mag and VLF surveys. 1984-1987 B.P. Selco optioned the property from bob Fairservice and geologically mapped the property, soil sampled, conducted I.P. surveys and did limited hand trenching. In conjunction they also drilled twelve diamond drill holes (2430m's) on the main zone. 1988 Noranda/Noront conducted a small humus sampling program. 1990-1992 Phelps Dodge Corporation conducted additional geological mapping, I.P. surveys and work culminating in an additional five diamond drill hole program (700m). Since 1992 to staking the property in 2006, no work has been recorded. 2006 & 2008: Teck Cominco Ltd. conducted a 2006 and a 2008 geological mapping and sampling program on the 'Lobstick Property'. * see Deposit Comment - Mineralization for assay results.

Province: Superior
Geological Age: Precambrian
Feb 15, 2011 (J Bongfelt) - The Lobstick property is located in the northwestern portion of the Wabigoon subprovince and covers the central portion of the Berry river formation which is a portion of the Warclub group. The property is just northeast of the junction of two regional scale fault systems namely the Pipestone-Cameron Lake fault and the Wabigoon fault systems. The property covers a western portion of the late stage sediment dominated Warclub group which hosts other disseminated gold systems to the east, namely the Plomp Farm and Thunder Lake properties. (Kenora AF 52F/05NW, DD-1, Teck Cominco, Report - pg.5)
Feb 15, 2011 (J Bongfelt) - The Lobstick property covers lower amphibolite facies rocks of the Berry River Formation. The past regional mapping had identified proximal vent volcanics over much of the property and previous B.P. Selco work had also identified subvolcanic intrusives on the property. Much of this previous work was confirmed in the 2006 geological work. Lithologies on the property are dominated by QFP dacites to rhyolite in composition with a generally pale grey to yellow aphanitic and commonly weakly foliated matrix with variable 5-15% 1-3mm plagioclase phenocrysts and 10-20% 15 mm quartz phenocrysts. Occasional fragmental sections appear randomly and are difficult to follow on strike and often display a primary pyroclastic texture with generally fragments consisting of the same composition as the groundmass.

Feb 15, 2011 (J Bongfelt) - Best assays: 0.03 to 0.63 oz./ton Au - surface samples, 1945 (Kenora AF 52F/05NW, H-1, Thrasher Claims) The main historic showing noted as the BP A&B trenches on map #5 is located on the southeast side of Lobstick Bay, and the highest values in the 2006 sampling were returned from here. Historically grab samples from this area have returned values up to 13,100 ppb Au and channel sampling has returned values up to 2100 ppb Au over 2.6 meters. Drilling by B.P. under this showing have returned similar values at a shallow depth but the potential is demonstrated by holes such as LB-01-03 located 200 meters to the northwest of the historic trenches. Hole LB-01-03 returned values of 0.602 glt Au over 17.76 meters (including 2.10 glt Au over 4.76 meters then the zone was intruded by a late mafic dyke and was followed with a further 0.696 glt Au over 18.57 meters (including an interval of 1.32 glt Au over 4.57 meters). This hole is under Lobstick Bay near a swamp and demonstrates the potential in this subdued poorly exposed corridor. B.P. Selco (Pryslak) had postulated a archean epithermal prospect being present with the unusual presence of fluorite in the system. * This information proves this MDI to be a “prospect”. (Kenora AF 52F/05NW, DD-1, Teck Cominco, Report - pg.9) Sampling in 2006 by Teck Cominco returned maximum values of: 936ppb Au, 592ppb Hg, 114ppm Zn, 173ppm Mo, 77ppm V, 45ppm As and 15ppm Sb. (Kenora AF 52F/05NW, DD-1, Teck Cominco, Report - pg.9) Sampling in 2008 by Teck Cominco returned maximum values of: 0.08ppm Au, 1.86ppm Ag, 169ppm As, 8670ppm Ba, 18ppm Bi, 5% K, 16ppm Mo, 6% Na, 328ppm Pb, 18ppm Sb, 10ppm TI, 16ppm W.
