The claims fall within the Cretaceous/Eocene Age Nechako Basin which has recently become a significant gold environment with targets including the Newton Hill occurrence located 90 kilometers to the west, the Blackwater Davidson occurrence located 220 kilometers to the northwest and the Blackdome Mine located 18 kilometers to the south.
Heavy mineral samples from several small drainages within the area of the claims returned very high gold values with some exceeding 10 g/t Au. A subsequent search of assessment records indicates that part of the current claims was staked a few years later and re-sampled confirming the initial results with heavy mineral sample results of up to 20 g/t Au being obtained. The assessment report indicates that only four rock samples were collected and it appears that follow-up was minimal.
