The Nikko, or Nikco, occurrence is situated approximately 1.2 kilometres southwest of Kitchener.

Regionally, the area is underlain by the Middle Proterozoic Purcell Supergroup, a thick succession of siliciclastic and lesser carbonate rocks. The Purcell Supergroup is well known for hosting a number of significant deposits including the Sullivan (MINFILE 082FNE052) sedimentary exhalative lead-zinc deposit and the Troy copper-silver deposit in Montana.

The claim area is underlain by the Aldridge Formation, the lowermost division of the Purcell Supergroup. The Aldridge Formation is composed of turbiditic siliciclastic rocks, quartzofeldspathic wacke and siltstone and numerous gabbro sills and/or dikes of the Middle Proterozoic Moyie intrusions.

Mineralization is hosted by a metadioritic Moyie sill. The sill occurs within the Aldridge Formation and dips 20 degrees southeast. The Iron King 7 showing, situated to the southwest, is believed to be a more eastern exposure of the same mineralized sill.

Mineralization was discovered in 1966 or 1967 by Arthur Johnson, who subsequently staked a variety of claims over the area. Johnson conducted several prospecting programs and sent property submissions and grab samples to a variety of mining and exploration companies.

The Nikco #7 claim was staked by Johnson in November 1975 along with the Iron King #7 claim situated to the west of the Nikco claim. In 1976, G.W. Laforme of Chevron Standard Limited visited the Iron King property to conduct a brief examination. Laforme collected eight chip samples from existing pits on the Iron King #7 claim and two grab samples from Pit #8 and the south side of Sullivan Creek. Due to an access road being washed out, Laforme was unable to visit the Nikco claim at that time.

Cominco, Phelps Dodge Mining Corporation of Canada and Echo Bay Mines visited the property and conducted superficial examinations sometime prior to Chevron Standard Limited’s visit in 1976. According to field notes taken by Chevron staff in 1976, Echo Bay Mines visited that year and collected five samples, and Comino and Phelps Dodge collected at least one sample each on an unknown date. The Phelps Dodge sample is the only one known to have been collected on the Nikco (New Nickel) 7 claim.

In 1979, Cyprus Anvil Mining Corporation visited the property and collected three grab samples that returned variable copper and low-grade nickel values. Based on the sample results, Cyprus Anvil declined any further involvement in the property.

One sample collected by Phelps Dodge assayed 0.5 per cent copper and 0.5 per cent nickel (Property File, Laforme and Chevron Standard Ltd. Minerals Staff, October 2, 1976, page 1).

During 2004 through 2012, Eagle Plains Resources Ltd. completed programs of geological mapping, geochemical (soil and rock) sampling and airborne geophysical surveys on the area as apart of the Iron Range property. A completed property exploration history can be found at the O-Ray (MINFILE 082FSE017) occurrence.
