ASX Overview Map |
The Mag Hill target area is an IOCG plus uranium drill prospect at Contact Lake.
The Mag Hill target is the site of the most extensive hydrothermal magnetite-actinolite- feldspar-apatite plus sulphide alteration along the Contact Lake Mineral Belt in the northern part of the Great Bear Magmatic Zone. The host rocks are alkali (sodic or potassic) and or actinolite-epidote altered andesites. The core zone comprises a pervasive alkali feldspar-scapolite-magnetite-actinolite-apatite hydrothermal assemblage.
The alteration signature and zone at Mag Hill is similar to that of the Port Radium- Eldorado uranium mine area situated on Labine Point, NT. The Mag Hill target area is defined by predominately pyrite mineralization, which is present intermittently throughout the Mag Hill region and in an extensive gossan at the southeast end of Echo Bay, with minor amounts of visible malachite. In addition, uranium, cobalt, nickel, copper, silver, lead and zinc enrichments are present locally as veins, veinlets and disseminations that extend outward in the southern and eastern extensions of the Mag Hill area.
Mag Hill Target area -Contact Lake, NT- grab samples assayed
- 0.69% U3O8 and 30.9 g/ton silver and 0.32% lead (the maximum uranium values returned from the assayed samples)
- 0.38% U3O8 and 30.5 g/ton silver and 0.24% lead
- 0.31% U3O8 and 7.8 g/ton silver
This region is being targeted for detailed uranium exploration due to its notable similarities to the Port Radium-Eldorado mine region with regard to hydrothermal alteration and mineralization and large size of the associated hydrothermal system, 1-2 km2 core zone of magnetite-actinolite-apatite alteration, kilometre-scale surface gossans and distinct lenses of poly-metallic sulphide mineralization.
The Company analyzed over 121 surface grab samples from the Mag Hill Grid over a 5 square kilometer area in the southern portion of the Contact Lake belt. 25 samples collected were variably enriched in uranium, silver, copper, lead, zinc, nickel and cobalt. The rock samples assayed to a maximum of 0.69% uranium, 68.0 g/ton silver, 4.98% copper, 0.40% lead, 0.49% zinc, 0.23% nickel, 0.58% cobalt, 0.4 g/ton gold and 0.10% bismuth.
(See attached table for analytical results of surface grab samples)
