The showings are situated less than 61 metres from tidewater at the east entrance to Poole Inlet on Burnaby Island.

The Flo group of 24 recorded claims was held in 1964 by Merrican International Mines Ltd. The company completed 152 metres of diamond drilling in the vicinity.

The area is underlain predominantly by massive grey limestone and black, thin bedded limestone of the Upper Triassic Sadler and Peril Formations (Kunga Group) and lithic siltstone and greywacke of the Lower Cretaceous Longarm Formation. A monzonitic intrusive of the Middle to Late Jurassic Burnaby Island Plutonic Suite occurs east of the showing.

A magnetite replacement zone, 40 by 30 metres, occurs in Kunga limestone near a major north trending fault. Assays on four samples from diamond drilling in 1964, ranged from 60.80 per cent to 69.60 per cent iron (National Mineral Inventory Card 103B6 Cu10).

About 180 metres east of the magnetite zone, chalcopyrite outcrops in the limestone as two occurrences, 60 metres apart, with lengths of 9 and 22 metres, respectively. Widths range from 3 to 4.5 metres, with assays showing 4 per cent copper and 1 per cent copper (Minister of Mines, Annual Report 1964, page 46).
