[1][2] The primary commodities mined at O'Connor was copper, sulfur/pyrite and nickel.

[3] A number of small lenses of massive pyrite with much disseminated material have been opened up along the foot-wall of a sheared diorite sill near the northeastern arm of Lake Temagami.

In 1962, the Candela Development Company dug trenches and drilled four diamond drill holes totaling 376.1m and found 11.3m of sulphide averaging 0.5% copper and another 2.4m averaging 0.47% copper and 0.22% nickel.

In 1970, the Milestone Exploration Company held the claim for the O'Connor prospect.

[4] A 2022 UAV magnetic survey and prospecting report suggested that further sampling was in order.
