Brilliant Mining Corp.: Increased Grade Improves Economics at Winner Lanfranchi Nickel Mine, Kambalda District of Western Australia

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - April 4, 2007) - Brilliant Mining Corp. (TSX VENTURE:BMC) ("Brilliant" or the "Company") today announced that ongoing evaluation of the Winner orebody has increased the grade resulting in a 13% increase in tonnes of nickel metal in both the Probable Mineral Reserve and Indicated Resource at the Lanfranchi Nickel Mine in the Kambalda District of Western Australia.

Key Point Summary

- Winner Probable Mineral Reserve increases 13% to 144,003t grading 4.26% Ni containing 6,139t Ni metal; Increase of 712 contained Ni metal tonnes

- Winner Indicated Resource increases by 13% to 111,680t grading 6.16% Ni containing 6,879t Ni metal; Increase of 769 contained Ni metal tonnes

- Winner mining method allows a resource to reserve conversion rate of 96%

- Box-cut is complete and decline development on track with first ore scheduled for August 2007

- Mine scheduled to produce ore at 8,000-10,000t per month (340-420t per month contained nickel)

"The integration of production from Winner into the mine schedule in August will add significant nickel tonnage to the production profile during 2007/08 and is another step towards the Lanfranchi Joint Venture achieving our target of 10,000 tonnes contained nickel metal per annum for 10 years," stated Brilliant Mining CEO John Williamson. "The development of Winner should result in significant cashflow for the Company with nickel prices forecast to remain strong for the foreseeable future."

Ongoing evaluation of the Winner orebody has produced a new Indicated Resource estimate resulting in a 13% increase in contained nickel metal over the previous resource estimate (See press release dated July 12, 2006) as shown in Table 1.



Table 1: Winner Resource(i)
---------------------------------------------------------
Resource Date Category Tonnes Ni % Ni Tonnes
---------------------------------------------------------
March 2007 Indicated 111,680 6.16 6,879
---------------------------------------------------------
July 2006 Indicated 110,500 5.56 6,100
---------------------------------------------------------


Subsequent to the resource upgrade, the mine design optimization was completed and a new Probable Mineral Reserve of 144,003 tonnes at 4.26% Ni containing 6,139 tonnes Ni was estimated resulting in an increase of 13% or 712 tonnes of nickel metal over the previous reserve estimate (See press release dated October 12, 2006) as shown in Table 2. The proposed mining method is cut and fill with paste backfill, which is similar to the method used at the Helmut South orebody. This method will ensure high ore recovery rates and maximum flexibility to deal with any unexpected changes in geometry. It also provides us the ability to mine additional ore outside the current resource base, if later discovered. The mineable reserve for Winner has a resource conversion rate of 96% excluding any resource outside the current mine plan.

Reserve Date Category Tonnes Ni % Ni Tonnes
---------------------------------------------------------
March 2007 Probable 144,003 4.26 6,139

The Winner orebody is located approximately 1km east of the main Lanfranchi workings and up-dip of Schmitz. The orebody is 155m below surface and has an elongated cigar shape with a plunge of 30-40 degrees which is typically 10-20m thick in the east/west plane and 30-60m thick in the north/south plane. The mineralization is predominantly massive sulphides on the basalt ultramafic contact with minor disseminated sulphides hosted in the ultramafic.

(i) The tonnes and grade of the updated resource/reserve are the ore constrained within the interpreted ore wireframes which were constructed on sectional interpretations at 20m centres to a 1.0% Ni cut-off grade. Internal dilution not exceeding 6m down-hole was included in some instances to allow for simplification of wireframing and modelling.

This updated JORC-compliant, resource and reserve estimate (Summarized in Tables 1 and 2 - March 2007) has been prepared by BM Geological Services Pty Ltd. and Lanfranchi Nickel Mine's personnel; and has been reconciled to the mineral resource and mineral reserve categories as set out by and adopted by the CIM Council.

Development Schedule

The duration of the overall project remains unchanged and is expected to be 29 months, based on four months for surface works (now completed) and 25 months of decline development and mining (well underway).

Completed



- October 2006 Statutory approvals
- November 2006 Excavate box-cut
- January 2007 Commence decline development
- March 2007 Decline 50m below surface


Target



- August 2007 First ore delivered to surface


Benefits/Opportunities

- Winner adds significant Ni production for the Lanfranchi JV from August 2007

- High grade Winner ore blended with Helmut South ore will improve grade and payability

- Scope for discovery of additional ore on sidewalls, up-dip and down-dip of current resource shape

- Additional production will spread fixed costs over larger tonnage thereby reducing overall mine unit costs

- No significant geotechnical risks

- Winner opens up another orebody with separate decline access improving flexibility of mine operations and scheduling

Brilliant Mining Corp. owns a 25% interest in the Lanfranchi Joint Venture ("Lanfranchi JV"), which owns the Lanfranchi Nickel Mine together with associated infrastructure, mining leases and mineral claims. The remaining 75% interest in the Lanfranchi JV is owned by Sally Malay Mining Limited.

The project is supervised by John Williamson, PGeol, of Edmonton, Alberta, CEO and a Director of Brilliant, and is the qualified person as defined in National Instrument 43-101.
