Point Location Description: Trench
Location Method: Conversion from MDI
Access Description: Access to the Lumby Lake Zone is obtained by travelling 40 km north along the Premier Lake Road from Sapawe (located at the terminus of Highway 623) to a secondary logging road. After travelling a further 1.3 km north along the logging road, the surface showings associated with this prospect (No. 1 Pit, Anderson West Trenches, Anderson, Beaver Dam) can be accessed by using the ATV trail that runs to the east from this location. The Anderson showing trench is located approximately 700 m east of the logging road and 200 m south of the ATV trail.
The earliest prospecting activity in the Lumby Lake area began during the 1890s and culminated in the discovery of the Golden Winner gold deposit at Longhike Lake, approximately 5 km southwest of Lumby Lake. Development of the Golden Winner Mine resulted in the production of 15 tons of ore during 1899-1900. Between 1913 and 1918, exploration activity focused on pyritic iron occurrences in the Cryderman-Pinecone Lakes area. Exploration interest increased markedly in the late 1930s after the discovery of gold-bearing float near Lumby Lake by the Geological Survey of Canada. Since that time, exploration efforts by numerous prospectors and exploration companies have resulted in the discovery of several gold and base metal occurrences in the vicinity of Lumby Lake. One of these historic occurrences (Anderson showing) is located in the central portion of the Lumby Lake Zinc property. A summary of exploration work that has been documented on the Lumby Lake Zinc property is provided below. 1950: L.C. Anderson - prospecting, sampling and assays. 1951: Noranda Exploration Company Ltd. – geological mapping, trenching and diamond drilling (9 diamond drill holes for 736.7 m). 1954: Balacen Mines Ltd. – diamond drilling (1 ddh for 152.4 m). 1970-72: Univex Mining Corp. – ground magnetic and electromagnetic surveys, diamond drilling (5 ddh for 520.3 m). 1975: Kerr Addison Mines Ltd. – ground magnetic and electromagnetic surveys, geochemical survey and diamond drilling (1 ddh for 63.4 m). 1981-82: Mining North Explorations Ltd. – prospecting, trenching, stripping, sampling, geological mapping, ground magnetic and electromagnetic surveys. 1986-89: Premier Lake Resources. – prospecting, geological and geochemical surveys, ground magnetic, electromagnetic and IP surveys, diamond drilling (7 ddh for 1213.7 m). 1998-2005: D. Saunders – prospecting, trenching, sampling, ground magnetic, electromagnetic and IP surveys. 2006-07: Probe Mines Ltd. – diamond drilling (17 ddh for 1913 m).

May 28, 2015 (Mark Puumala) - The following is excerpted from OFR 6303: The geology of the Lumby Lake Zinc (formerly known as Anderson) property has been described previously by Woolverton (1960), Jackson (1985), Schnieders and Dutka (1985) and Buse et al. (2009). Bedrock exposures on the property are typical of the Lumby South assemblage rocks which have been described by Buse et al. (2009) as follows. The Lumby South depositional sequence is dominated by massive mafic metavolcanic flows that conformably overlie the felsic tuffaceous units at the base of the greenstone belt. The mafic volcanic rocks make up repetitive successions of synvolcanic gabbros overlain by massive basalt, pillowed basalt, pillow and flow-top breccia with varying amounts of hyaloclastite in the pillow selvages and hyaloclastite breccia. Amygdules occur locally throughout the Lumby South depositional sequence and are often irregular and filled with plagioclase or quartz. Pillow selvages are 0.8 to 1.0 cm thick on average, whereas pillows are 20 to 50 cm wide with ovoid to bulbous shapes. Many of the pillows are “eyebrow-shaped” and drape over each other. In the Lumby and Spoon lakes area, felsic tuffs are interbedded with thin mafic metavolcanic flows that are commonly massive and may contain amygdules that are 1 to 2 cm in size. The felsic tuffs are generally 1 to 5 m thick and often concentrate the dextral shearing along the margin of the greenstone belt; furthermore, the felsic tuffs commonly contain copper-lead-zinc-silver mineralization.

May 28, 2015 (Mark Puumala) - Surface occurrences within the Lumby Lake Zone include the Pit No. 1, Anderson (consisting of the main occurrence and west trenches), Beaver Dam and A-Zone occurrences. Significant diamond-drill intersections of base and precious metal mineralization have also been reported from the Lumby Lake Zone, with the zone having been delineated as far east as Premier Lake Resources Ltd. diamond-drill hole 88-2 (Wagg and Holmstead 1990). Descriptions of the Anderson, Beaver Dam, Anderson West, and Pit No. 1 occurrences, as well as the mineralization encountered in ddh 88-2 can be found in OFR 6303.

Geologist: Mark Puumala
Notes: The following is excerpted from OFR 6303: Stripped outcrops located at the Pit No. 1 area (UTM Zone 15, 620650E 5432767N) consist of gossanous exposures of felsic metavolcanic rocks. These rocks are strongly deformed, exhibiting zones of intense silicification and sulphide mineralization. Disseminated pyrite is found throughout the mineralized zone, while the silicified zones contain sphalerite-rich stringer zones and disseminated chalcopyrite. Foliation at this location strikes 290º and dips 65º to the north. Two samples were collected from the No. 1 Pit area. Three grab samples were also collected from trail-side outcrops and a trench located in the Beaver Dam occurrence area. The rocks in this area consist of sheared felsic metavolcanic rocks that are mineralized with 3 to 5% disseminated sulphides. Assay results for the samples referenced above are available in OFR 6303.
