Past work on the Oakes project includes two drill campaigns, more recent VLF, Mag and IP geophysics in addition to a soil chemistry survey and trenching campaigns. Historical drilling by Hard Rock Gold Mines includes 7 short, BQ-sized holes drilled between 1949-51. Five of the drill holes from the 1950s intersected gold grades above 3 g/t . Only a few rare pieces of core from these past programs are available such that the old work will need to be confirmed and incorporated into new work being conducted by Riverside to produce bonified exploration targets. Drill logs report the mineralized zones that were sampled historically comprised quartz-carbonate veins within sheared mafic volcanics with sulphide mineralization (pyrite, chalcopyrite and galena). This drilling campaign was conducted to trace known veins discovered at surface at depth.

In 1993 in a different area two holes were drilled by Greater Lenora Resources Corp. to test two coincident VLF and copper-in-soil geochem anomalies. Drill logs from the historical reports show the mineralized zones that were sampled comprised meta-basalts (greenschist to amphibolite facies) and tuffs showing silicification and sulphide mineralization (pyrite, chalcopyrite and pyrrhotite). Hole GL-93-1 was drilled to a depth of 153 m and returned anomalous results in gold and copper. Hole GL-93-2 (155 m) intersected an 8.3 m length of semi-massive pyrrhotite mineralization starting at 112m down hole with one, 1.5 m long sample returning 3.3 g/t gold. The emphasis of this exploration appears to have been exploring for copper.

More recent work conducted by Golden Chalice Resources (2010-12) included an IP survey and a trenching campaign. The trenching campaign identified several mineralized shears coincident with VLF and IP chargeability geophysical anomalies. The best trench of six, Trench #1, returned three channel samples of 4.77, 4.17 and 3.41 g/t gold within shear-hosted quartz-carbonate veins. In addition, 26% of the 20 samples taken at Trench #1 returned greater than 1 g/t gold. The best composite sample results from this older work in Trench #1 were 1.3 g/t over 4 m and 1.32 g/t over 4 m. None of the trench work has been followed-up on and most of the complimentary geochemical anomalies have not been drilled. Riverside sees ample opportunity at Oakes to further consolidate the past work and build on the survey work that has showed positive results for gold so far. Riverside in July of 2019 sampled selective sections of the shear zones showing sulphide mineralization that retuned good gold values of 19.7, 31.9 g/t and 6.9 g/t (see press release dated July 29, 2019)

Riverside’s fieldwork indicates gold mineralization at Oakes is hosted within shear zones along contacts between mafic volcanics and gabbroic sills or felsic volcanics and less commonly with diabase dikes.
