The Carmax website can answer some of these questions.

Imperial Oil Ltd. optioned the property in 1970 and drilled 30 diamond drill holes between 1971 and 1976. Esso Resources Ltd (formerly Imperial Oil) with joint venture partner Nuspar Resources drilled a further 25 holes between 1977 and 1981.

Carmax acquired the property by staking after Homestake Mining let the claims lapse and has expanded the claims to cover 11,410 hectares.

That means that none of the original people remain. There is a report probably available on SEDAR that details all the botched drilling, etc. from before.

The company notes that due to non-standard sampling techniques in historic drilling, some of the past drill holes were not included in the current in-pit resource estimate.
