Achieved final critical milestones, completing a successful silicon pour
MONTREAL, QUEBEC--(Marketwire - Feb. 14, 2008) - URANIUM BAY RESOURCES INC. (TSX VENTURE: UBR) is pleased to give its shareholders a third update on the progress of the diamond drilling campaign started in October 2007 from its wholly owned 314 km2 Uskawanis Uranium Property ("UUP") situated SE of Hydro-Quebec's Opinaca Hydroelectric Reservoir along the Eastmain River, 180 km SE of Radisson, Quebec.
Review of Project Aims and Expectations
The Uskawanis Uranium Property is being prospected for a Rossing type uranium deposit. The Rossing deposit (in Namibia - south-western Africa) is a very large low grade, essentially mono-mineralic uranium deposit (with associated thorium) that is mined as an enormous open-pit operation. The principal exploration target is multiple large intrusive mineralized alaskites (pale/ white pegmatites). These pegmatites must be intruded in close proximity to each other to generate sufficient mining tonnage. Individual dykes may be up to 20-30 metres in thickness and mining volume can only be created by many dykes in close proximity as is the case at Rossing.
This type of deposit will give widespread airborne radiometric anomalies for uranium and thorium as mineralized pegmatites can be spread over a large area. In general however it is anticipated that several core areas will be identified where the uranium grade is highest and dykes are more abundant.
Average uranium levels in a granite may be as high as 3 to 4 parts per million (3 to 4 ppm). Uranium levels in alaskitic pegmatites that are x25 background (between 75 ppm to 100 ppm) are significant and indicative of Rossing type mineralization.
Currently (2007), Rossing Mine average grade is around 0.032% or 320 ppm U308 (approximately x100 granite background values), but at current uranium prices, it is understood that Rossing Mine can economically mine a grade as low as 80 ppm (approximately x25 granite background values).
THEREFORE THE HYPOTHESIS THAT THE USKAWANIS URANIUM PROPERTY IS A ROSSING TYPE DEPOSIT HAS BEEN CONFIRMED.
The salient features of the results to date can be summarized as follows:
- Radiometric anomalies identified from ground and airborne surveys have been found on granites/ pegmatites over a large part of the project area;
- The presence of mineralized alaskites (pegmatites) was initially demonstrated in outcrop;
- 25 drill-holes have been logged and many have radiometrically active pegmatites demonstrating mineralization in the third dimension;
- Down-hole-logging has demonstrated elevated uranium/ thorium values in several drill-holes;
- Down-hole radiometric logging has demonstrated mineralization over substantial widths (greater than 70 m);
- Geochemical results from drill-hole USK-02 confirm intersects of U308 mineralization over substantial widths with 76 ppm over 95 metres (1-96) including 16 metres at 100 ppm (77-93) and validate the Radiometrically down-the-hole readings values obtained;
- Radiometrically down-the-hole logging readings varying from 500 counts per second (or cps) to over 4,000 cps, intersected over depth
- Logging of drill-holes has shown extensive metasomatism (complete alteration of rock due to mineralized fluids) typical of the Rossing deposit;
- Uranium mineralization has been shown associated with multiple dykes (dyke swarms);
- The hypothesis that the UUP is a Rossing type deposit has been confirmed.
Uskawanis Uranium Property program update
Initial uranium anomaly identification on the UUP was completed between June and August 2007 by ground survey teams using Radiation Solutions Inc spectrometers. These surveys identified radiometric anomalies in pegmatitic/ granitic rocks. Grab samples taken indicated uranium anomalies varying from 500 counts per second (or cps) to 65,535 cps, and 30 ppm to 11,465 ppm equivalent uranium assay values (or eU). The more than 140 chemical assay results gave uranium values ranging from trace to 1% U3O8 (refer to news releases dated July 19, 26 and 31, 2007).
During June and July 2007 Geophysics GPR International Inc, flew an airborne radiometric survey of the UUP using an airborne spectrometer. Some 3,537 line kilometers were flown. This data was presented to UBR November 2007.
Uranium Bay's autumn 2007 drilling campaign drilled 25 drill-holes numbered USK-01 to USK-25. The drilling was initially investigating "spot" uranium anomalies located during the field survey near helicopter Pads 1, 7, 40 and 42. Drill-holes located adjacent to these anomalies failed to find any continuity of high grade mineralization to depth.
Interpretation of the airborne radiometric data, after it became available during the drilling programme, showed several areas of significant elevated uranium levels. These were more typical of the type of anomalies expected with Rossing style mineralization. Unfortunately, in general, these were east of the area investigated by the field teams and there was no ground information available to the UBR team about these anomalies.
Careful location of the position of the drill-holes showed that several holes were on small airborne radiometric anomalies. Down-hole-logging demonstrated that many of these boreholes had continuity of low grade mineralization. It is now understood that the geology of the area consists of an early granodioritic rock cut by a later monzonite that has in turn been intruded by late phase alaskitic pegmatites. It is some of these pegmatites which are significantly uranium/ thorium enriched.
All boreholes have now been down-hole radiometrically logged and several long mineralized intersections have been demonstrated.
UBR has just received the first geochemical results from ALS Chemex for drill-hole USK-02. See the attached diagram for the location of USK-02 and a table of the results available.
As can be seen uranium levels are elevated throughout the borehole with 95 metres (1-96) at 76 ppm, and some 16 metres (77-93) at 100 ppm being more than x25 typical granite background (between 75 ppm to 100 ppm).
These results are viewed by UBR as highly significant. They clearly support the belief that the UUP has the potential to contain a Rossing type deposit.
Further results will be released as they become available.
Mr. Bernard Tourillon, UBR's President and CEO comments: (...) The drilling still supports our original working hypothesis suggesting that the style of targets found on the Uskawanis Uranium Property may be similar to the bulk-type uranium mineralization found in Namibia at the Rossing Uranium Deposit (...) The Company's goal is fixed on identifying an economic bulk mineable target within the broad region of anomalous U3O8 at Uskawanis (...)
