Silver
Spruce Resources Inc. And Universal Uranium Ltd. Announce An Initial
Mineral Resource Estimate At The Two Time Zone
Highlights
- Indicated Mineral
Resources of 2.33 M lbs U3O8; Inferred Mineral Resources of 3.73 M lbs
- Two Time Zone is open
at depth and along strike to the south
April 29, 2008 - Bridgewater, NS - Silver Spruce Resources
Inc. (TSXV: SSE) and Universal Uranium Ltd. (TSXV: UUL) are pleased to
announce an initial Mineral Resource estimate for the Two Time Zone on
the CMB NW property in the northwestern part of the Central Mineral Belt
of Labrador.
Scott Wilson Roscoe Postle Associates (Scott Wilson RPA) has prepared a
Mineral Resource estimate for the Two Time Zone using drill hole data
available as of February 4, 2008. The Two Time drill hole database
includes 40 diamond core holes (holes 1-23 and 25-41) totaling 10,928
metres, plus five surface trenches.
The Mineral Resources are contained within eight zones, D101 though D108.
At a cut-off grade of 0.03% U3O8, Indicated Mineral
Resources are estimated to total 1.82 million tonnes grading 0.058% U3O8
2.33 million pounds U3O8. Inferred
Mineral Resources are estimated to total 3.16 million tonnes grading
0.053% U3O8 containing 3.73 million pounds U3O8.
A set of cross sections and plan views were interpreted to construct
three-dimensional wireframe models at a cut-off grade of 0.03% U3O8,
and a minimum true thickness of four metres. These criteria reflect a
potential underground bulk-mining scenario. High U3O8
grades were cut to 0.3% U3O8 prior to compositing
to two metres. Variogram parameters were interpreted from two-metre
composited assay values. Block model U3O8 grades
within the wireframe models were estimated by ordinary kriging.
Classification into the Indicated and Inferred categories was guided by
the drill hole density, interpreted variogram ranges, and the apparent
continuity of the mineralized zones. See Table 1, following, for details.
The Two Time Zone was discovered during ground follow up of a regional
radiometric survey in the fall of 2006 and was first drilled in December
2006. Drilling continued through 2007 and the resource definition program
was completed on December 15, 2007. The
Two Time Zone, like most of the CMB NW property, lies outside of lands
administered by the Nunatsiavut government that are subject to the
recently announced moratorium on uranium development.
"We have come a long way since the discovery of the Two Time uranium
zone in the fall of 2006, and now have the first "newly
discovered" resource to be defined in the Central Mineral Belt since
the 1970s," stated Lloyd Hillier, President and CEO of Silver
Spruce. "These resources establish Silver Spruce and Universal
Uranium as companies with a significant uranium deposit at the Two Time
Zone. We look forward to increasing the size of the deposit and making
further discoveries as we continue our follow up exploration."
Infill diamond drilling and drilling to test the strike extensions and
the down plunge extension of the Two Time Zone are planned for the second
quarter of 2008. A second drill will focus on the Firestone Zone (see
news release dated October 17, 2007) and other regional targets that have
been generated on the CMB NW property.
Table 1 summarizes the Mineral Resources estimated by Scott Wilson RPA. A
table giving the significant results for the infill drilling for holes
CMB-07-25 to 41 and the plan maps and sections for the drilling on the
Two Time Zone can be viewed on the Silver Spruce and Universal Uranium

Notes:
- CIM definitions
were followed for mineral resources.
- The cut-off grade
of 0.03% U3O8 was estimated using a U3O8
price of US$65/lb and assumed operating costs.
- Grade-shell
wireframes at 0.03% U3O8 and a minimum true
thickness of four metres were used to constrain the grade
interpolation.
- High U3O8
grades were cut to 0.3% prior to compositing to
two-metre lengths.
- Several blocks
less than 0.03% U3O8 were included for
continuity or to expand the lenses to the four metre minimum
true thickness.

All uranium analyses are
performed by Activation Laboratories in Ancaster, Ontario, an approved,
accredited laboratory, using the delayed neutron activation technique
(DNC), which gives accurate results for samples carrying up to 1.0%
uranium. In addition, samples are analysed using an ICP technique that
gives good results for most other elements, including Thorium. A quality
assurance/quality control (QA/QC) program, described on the companies'
websites, has been implemented by the Silver Spruce/Universal Uranium
joint venture to increase confidence in the results generated.
ABOUT THE CMBNW PROPERTY
The CMB NW block is part of
the Silver Spruce (SSE)/Universal Uranium (UUL) CMB/Seal Lake joint
venture previously announced. The property is held 60% by UUL and 40% by
SSE.
