Church Uranium-Germanium-Molybdenum Deposit
North Dakota

LOCATION:  The Church deposit forms the central 3,000 acre portion of the Sentinel uranium-germanium-molybdenum project, which covers in excess of 25,000 acres located in western, North Dakota USA.

STORY:  The target at Sentinel is multiple, near surface (less than 20 metres depth), stacked, sub-horizontal high-grade uranium–germanium-molybdenum mineralisation zones that occur at the top of coal (lignite) horizons. 

Resource drilling (419 holes) at the Church Deposit (the first of several prospects to be tested) was completed in late-2008 to assess the continuity and extent of mineralisation between and beyond the existing historic resources with the aim of developing high-grade near surface resources that can be developed by coal-style open pit mining.  Continuous mineralisation has been identified in drilling over in excess of 3km of strike and resource modelling is in progress with results anticipated to be released in early 2009.

In addition to the resource drilling, close spaced post-hole drilling designed to test the local scale continuity and potential mine-ability of the mineralisation shows excellent continuity and consistency of mineralisation, with the weighted average grade for all 12 holes assaying 0.105% U3O8, with mineralisation starting at or very near to surface.

Mining in the late 1960's from a small open pit (now rehabilitated) that occurs within the Church lease is reported as producing approximately 40,000 tons of ore grading 0.175% U3O8 from near surface.  Mining in the district ceased in the late 1960's when U3O8 was at $7 per pound.

Recent testwork indicates uranium metallurgical leach recoveries of 92% on beneficiated material whilst metallurgical testwork on germanium and molybdenum mineralisation is in progress.  The company believes that as the mineralisation occurs from surface and because of the gently dipping strata, the project provides an excellent exploration and development opportunity over large areas.

GEOLOGY:  Host lignite seams of the Sentinel Butte member of the Tertiary Fort Union Formation are flat lying to very gently dipping and are generally 0.5 to 5 metres thick with the upper 0.5 – 1.5 metre portion carrying the highest grades of uranium and molybdenum mineralisation, whilst germanium occurs in multiple stacked layers.
