The 3992 ha AB Property is located in the Mackenzie Mountains of the NWT, 263 km west of Norman Wells and 230 km to the NE of Mayo, Yukon. The closest float plane access is at Border Lake, located 10 km to the west of the property. Access to the property is via helicopter only. Staked in 2005, and then expanded in 2007, it is owned 100% by Eagle Plains with no underlying royalties or other encumbrances.
Historic work by Welcome North Mines first identified carbonate hosted Zn-Pb mineralization on the property in 1974. Eagle Plains Resources work, driven the carbonate-hosted Mississippi Valley-Type (“MVT”) Pb-Zn model, has been successful in improving the geological and geochemical knowledge of the property, adding to the known mineralization occurrences and locating highly prospective geophysical IP anomalies that could potentially represent large buried mineralization systems
- Numerous mineralized occurrences
- Excellent geology favourable for carbonate-hosted MVT base-metal deposits
- Untested high-priority coincident geochemical and geophysical targets associated with favourable geology
- Potential for world Class Ddeposit
- Encouraging exploration to date with comprehensive database
The dominant regional lithologies are thick-bedded limestone and dolomite beds belonging to the Cambrian Franklin Mountain and Sekwi Formations which overlie similar lithologies in the Proterozoic to Cambrian Backbone Ranges Formation. The Sekwi Formation contains skeletal, oolitic, recrystallized and silty dolomite members. All four members of the Sekwi Formation are mineralized, but the ooid layer appears from geochemical and geophysical analysis to be preferentially mineralized. The Franklin Mountain Formation also contains recrystallized, oolitic and silty dolostone members and mineralization is confined to the oolitic and skeletal members.
Two large E-W trending faults, 2 km apart, occur on the property. The more northern fault located near the center of the property appears to be an important conduit for mineralizing fluids. Many of the mineral showings are located near or on smaller faults splaying off and bounded by the two.
Geochemical results indicate that both structure and stratigraphy control mineralization at the property. The AB-Main Showing occurs close to deep seated structures that may have transported scavenged metals from a vast area and concentrated them in receptive units closer to the surface.
1974 to 1977 – The Arctic Red JV discovers the Zn-Pb AB-Main Showing, and a 263 m drill program intersects 30 m of disseminated sphalerite including 3 m of 12% Zn. Detailed ground-based exploration is conducted over the AB-Main. The AB-C Zone is discovered and trenching indicates that the lower high-grade bed extends at least 69 m horizontally with an average grade of 10%. Six diamond-drill holes over 476 m at the AB-C Zone reveal that all facies of the Sekwi dolostone are found to be mineralized.
Sampling of the mineral showings returned significant Zn values of:
||8.34% Zn over 5m
||10% Zn over 69m
||11% Zn over 2m
||AB-C Lower Showing
||6% Zn over 4m
||3.1% Zn over 2m
Eagle Plains Exploration
2005 – A reconnaissance level field program verifies target types and area potential, claims are staked.
2006 – Eagle Plains obtains over 5700 stream-sediment samples collected by Rio Tinto in the Mackenzie Mountains during the 1970’s. These are re-analyzed using modern techniques. Follow up prospecting investigates areas of anomalous silt geochemistry and the AB showings are examined.
2007 – Silt sampling following up prospective lithologies is conducted in the AB and AB-C Zone area.
2008 Eagle Plains Program
Mapping, prospecting, geochemical surveys and ground-based geophysics are conducted discovering 14 new mineralized occurrences, most notably the Link and Twist. Soil grids centered over the Main Showing and BAK Zone locate several multi-element (Pb-Zn-Fe) anomalous zones, several remain open.
Ground geophysics delineated a body of moderately high conductivity associated with the AB Main Showing and a strongly anomalous Zn soil anomaly. Another anomaly to the west of the creek is on strike and may represent continued mineralization similar to the AB Main.
Geophysics also located two extensive anomalies at the AB-C, with one appearing to be stratigraphically controlled over a 500 m strike length. The other is a 1 km length structurally controlled zone from the AB-C Zone to the Link Showing.
Geophysical and geochemical surveys have outlined prospective stratigraphy where an 8000 m diamond-drill program is recommended to test the mineralized horizons and showings. Additional geophysics, geochemistry and prospecting to infill areas that contain showings but did not have detailed coverage in 2008 should be undertaken. The diamond-drilling will focus on developing a resource at the AB-Main and AB-C Zones in addition to exploration drilling on some of the 2008 showings and newly defined targets.
Othere work includes additional mapping and prospecting in the Franklin Mountain Formation on high-grade showings characterized by white sphalerite.
