Exploration History

The first record of this property was E. S. Moore's Map of the Sturgeon Lake Gold published in 1911 (Moore, 1911). The map showed a claim, BG130, located on the south side of an east trending bay at the southern tip of the Horn peninsula between North Bay and North East Bay of Sturgeon Lake. Moore did not comment on the property. A shaft was sunk near the lakeshore and an area trenched. Up until 1952, BG130 remained on claim maps of the area. In 1969 the claim was re-staked as Pa 38180 and in 1980 the claim was leased. In 1974 the claim holder was Leon W. Green. He carried out stripping, trenching and additional excavation of pits on the property and surrounding claims. 1979: Rickaby Mines bought the property and carried out stripping, trenching, and sampling. In 1980-82: Rickaby Mines collected a small bulk sample which was shipped to a custom mill in Thunder Bay. Apparently, the results were unfavourable and the property was returned to the former owner. 1985: E. Roberecki carried out stripping. 1988: E. Roberecki carried out stripping, sampling, a humus geochemical sampling, and magnetic and VLF-EM surveys. 1994-97: E. Roberecki carried out prospecting, stripping and sampling. 2006: E. Holbik carried out prospecting, a beep mat survey, stripping, and sampling. 2017: E. Holbik carried out prospecting, sampling, and stripping.

Apr 29, 2020 (R Tuomi) - The style and type of mineralization is very similar to that found on Rainbow Island 1.5 km to the southwest of the Rickaby Mine property. The following is taken from p.96, O.G.S. Miscellaneous Paper 147, by Janes, D.A. et al, 1990: “An old water-filled pit or shaft is located just off the shoreline on this property. Rickaby Mines stripped and trenched a 100 by 40 m wide area to the northeast of the pit. At least six trenches were excavated along a shear zone trending 075 degrees and dipping 60 degrees. The shear zone is parallel to a breccia of angular 5 to 50 mm sized mafic metavolcanic fragments in a carbonate matrix. The breccia grades to the south into massive fine-grained mafic metavolcanics over a 0.5 to 1 m interval. To the northwest of the breccia, blue to black quartz veins up to 0.3 m in width carry pyrite, chalcopyrite and a few specks of visible gold. The black quartz veining is in contact with medium-grained grey granodiorite. Later dikes of feldspar porphyritic leucogranodiorite cut the shear zone and truncate at the carbonate breccia contact. The shearing and black quartz veining can be traced for 50 m along the 075 degrees trend into a contact with mafic metavolcanics where the veining pinches out. Gold assays from grab samples taken by the first author varied from 0.01 to 0.56 ounce gold per ton. The highest values were obtained from a sample collected from blue quartz in contact with feldspar porphyry approximately 60 m northeast of the pit. This area had been excavated to a depth of several metres and was partially water filled.”

Apr 29, 2020 (Therese Pettigrew) - A sample collected in 1988 by E. Roberecki returned 0.2 oz/t Au over 3 feet (6.85 g/t Au over 0.91 m) (Assessment report 52J02SE8668). Sample 8 collected in 1994 by E. Roberecki returned 0.026 oz/t Au (0.89 g/t Au) (Assessment report 52J02SE0002). The main vein is 3 m wide on average and is contact with fine grey granodiorite and mafic metavolcanics (Assessment report 20000014865).
