Hertz optioned two properties in the Bathurst Inlet area of Nunavut. These properties cover 5,046 hectares with uranium occurrences discovered during 1975-1976, and include the Pomie prospect by Cominco Limited, and the Yon showing by Noranda Exploration Co. Ltd.
The Pomie property consists of the Pomie, Pomie2, and Pomie3 claims and is located at the south end of Bathurst Lake. These claims cover ground around the Pomie uranium showing (076JSW0003).
The Yon property consists of the Yon claim and was staked to cover the historic Yon showing (076JNW0005), located near the southeast shoreline of Bathurst Inlet.
Access is currently by helicopter. The Bathurst Inlet Lodge is located 86 km from the Pomie property and 38 km from the Yon property and offers seasonal support.
The Pomie showing is a veintype uranium prospect in the lower Proterozoic (Aphebian) Brown Sound Formation of the Bathurst Inlet area. Exploration showed that anomalous radioactivity is confined to fractures in the lower basalt flow of the Brown Sound Formation and predominantly to its contact with the underlying arkosic sediments.
Since there is the Aphebian/Helikian unconformity in the middle Proterozoic, it could be hypothesized that the uranium mineralization at Pomie is an unconformityassociated uranium mineralization.
The Yon property consists of the Yon claim and was staked to cover the historic Yon showing (076JNW0005), located near the southeast shoreline of Bathurst Inlet.
The possible origin of the uranium mineralization at the Yon property is from hydrothermal fluids. These may have ascended from a basement source along fault zones and deposited mineralization within features in the brecciated rocks.
Pomie & Yon Geophysics
The magnetometer survey conducted at Pomie by Cominco produced a group of localized anomalies along the length the basalt flow. The anomalous zones contain relatively unaltered cores of material in altered basalt along a 1km zone.
Cominco also completed a radiometric survey at Pomie which concluded the anomalies are confined to the basalt and faulted basalt-arkose contact. These anomalies cover a substantial portion of the exposures of the lower basalt and it is reasonable to conclude that the material buried beneath the drift is similarly anomalous.
At Yon, detailed radiometric logs completed by Noranda were made on seven trenches and one outcrop, across the mineralized fracture. These logs gave fairly uniform curves, which were an indication of the width and grade of mineralization.
The Pomie and Yon claims sit within a prominent magnetic low anomaly that is localized to the regional fault structures that run parallel along the northwest/southeast trend between the respective properties.
The Cominco property surrounds the active claim containing the original Pomie showing drilled by Cominco back in 1977. Two out of seven drill holes (PM-3 and PM-7) gave very encouraging intersections of fracture-controlled and disseminated mineralization in the basalt flows which grade 2.59lbs U3O8/ton over 38 ft, and 4.79lbs U3O8/ton over 43 ft, respectively.
Noranda completed work programs in the 1970’s on the Yon property including thirteen trenches with a 1.5m channel sample yielding 0.33% uranium and the highest grab sampling returning 0.456% uranium.
Within the mineralized zones at the Yon showing radiation levels ranged from 2,500 to 10,000 counts per second using a TV-1A scintillometer.
Hertz aims to utilize modern exploration technologies to revisit strong historical results and hopes to define a distract scale uranium prospect in Nunavut.
