Access Description: The Beckington Lake road begins at the intersection with Hwy. 599 at the Provincial Highway garage 1.7 km south of Savant Lake village. The road runs south for approximately 3.5 km and then turns east to Wellington Lake where it turns south to East Bay of Sturgeon Lake.

Exploration History

1985: UMEX (Union Miniere Exploration and Mining Corp. Ltd.) conducted a geological and geophysical program over a block of claims on the east side of Sturgeon Lake parallel to the Beckington Lake Road. The primary targets of the program were base metal prospects but gold and other precious metals were included in the geochemical assaying program. The program centred on claims Pa 486032 and Pa 486040 which straddle the Beckington road.

Mineralization Comments

Dec 07, 2005 (R Tuomi) - The UMEX drill site B-16 is located to the north of the Beckington Lake Road 200 m northeast of the crossing of the narrow creek which eventually drains into the Northeast Arm of Sturgeon Lake. The drill had an initial bearing of 25 degrees and a dip of -54 degrees which flattened to -47 degrees at 320 m in length. The core contained a mixed section of silicified tuffs, garnet tuff, mafic volcanics, sericite schist and quartz porphyry. Zones with significant gold values were marked by increased black biotite in what appears to be mafic flows. Assays ranged from 0.018 ounce gold per tonne over 1.5 m to 0.375 ounce gold per tonne. A re-assay of the 0.375 ounce per tonne sample gave a result of 0.072 ounce per tonne.
