Township or Area: Horwood
Latitude: 48° 1' 44.54" Longitude: -82° 19' 29.73"
UTM Zone: 17 Easting: 401222.976 Northing: 5320377.088 UTM Datum: NAD83
Resident Geologist District: Timmins
NTS Grid: 42B01SW
Point Location Description: The point located is a small outcrop above water level at the south end of a grassy flooded area
Location Method: Data Compilation
Access Description: The showing is located 89km west southwest of Timmins and access is possible with a vehicle and a boat via Highway 101 to the Horwood Lake - Groundhog Lake turn-off. From this point an access road to Horwood Lake extends 11km south and then the showing is another 8km boat trip to an island east southeast of Blueberry Island.
1935 The showing was originally staked by P.H. Silams. 1947 H. Logan mapped and sampled the showing. During this work values up to $166/ton were reported. 1948 J. Lefever drilled a number of holes over a three year period and intersected some quartz veining. 1959 J. Lefever drilled additional holes. 1960 Kerr Addison carried out a magnetic survey which included the occurrence and drilled 7 holes. This work returned high gold and silver values over narrow widths and limited lateral extent. 1980 Raise Contracting / Ingamar Exploration carried out a magnetic and VLF-EM survey which covered the occurrence, then subsequently re-examined the surface exposures. 1986 Pelangio Larder Mines carried out a VLF-EM survey over the property. In the next three years Pelangio repeated the VLF survey together with an IP and magnetic survey, and then mapped the property. Following this work two short holes were drilled and 12 auriferous zones were intersected up to 1.5m thick with a maximum grade of 19 g/t over 30cm but otherwise values were less than 5 g/t over 30cm.

Metamorphism Type: Regional

Dec 07, 2005 (S Fumerton) - To the west of the showing the existence of a major north south fault has been inferred to underlie the axis of Horwood Lake.

Dec 07, 2005 (S Fumerton) - The occurrence is hosted in a medium grained diorite which is part of a sequence of Fe tholeiitic flows and tuffs which trend northeast. A strong carbonate alteration zone occurs in outcrop but has not been delineated in drill core and appears to be north of most quartz carbonate veins tested by drilling.

Dec 07, 2005 (S Fumerton) - Mineralization occurs as disseminated sulphides in a number of parallel quartz carbonate veins. These veins pinch and swell and are known to be up to 50cm thick but normally are up to 10 - 15cm thick. The veins have been traced laterally up to 60m. Typically the gold values are low but a section in one vein has consistently returned values between 14 and 118 g/t.

Date: Jun 30, 1992
Geologist: S Fumerton
Notes: The showing has been flooded when the lake was damned. None of the early work is apparent though it would appear than a zone of strong carbonate alteration presently outcropping on a small island to the north east was not drill tested in the past.
