Messina Minerals ("MMI") Resource and Exploration Updates

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - April 5, 2007) - Messina Minerals (TSX VENTURE:MMI) -


The Boomerang resource estimate from Snowden, expected in April 2007, will now be available in June 2007. This allows Messina time to complete 8 infill drill holes intended to change the mineral inventory classification in certain areas of Boomerang from lower confidence 'inferred mineral resources' to higher confidence 'indicated mineral resources' by decreasing the spacing between drill holes to within 50 meters apart.

The 60 day delay also allows Messina to expand the scope of Snowden's resource estimation to include Domino and Tulks East B Zone mineralized areas. Resource estimation for the western portion of the Domino mineralized zone only has begun, as has estimation of the Tulks East B Zone mineralization. These are expected to be available from Snowden in June 2007.


Messina contracted Snowden Mining Industry Consultants Inc. ("Snowden") (see NR December 19, 2006) to conduct a resource estimate on, and prepare a NI43-101 Technical Report for, the Boomerang zinc-lead-copper-silver-gold deposit located in Newfoundland, Canada.

Messina has received a draft report from Snowden documenting methodologies used to determine mineral resource boundaries at Boomerang. Based upon data from 67 diamond drill holes and using a tool called "kriging efficiency" among others, Snowden estimates that 67% of Boomerang is classifiable as indicated mineral resource, and 33% is classifiable as inferred mineral resource.

The classification of 'indicated' versus 'inferred' mineral resources is dependent primarily upon drill hole spacing: where drill hole spacing between pierce points is 50 meters or less, the Boomerang mineralization is estimated to be an "indicated mineral resource", as compared to the lower-confidence category of "inferred mineral resource" where drill spacing is greater than 50 meters or less. The addition of 8 infill drill holes, designed to bring the drill spacing to 50 meters or less in key areas at Boomerang, could change most of the inferred mineral resource to the higher confidence indicated mineral resource category.

Messina's objective is to obtain the highest 'confidence' mineral resource estimate for Boomerang which, when combined with metallurgical test results underway at Lakefield Research, can be used (with fewer assumptions) to better constrain economic parameters of 'scoping' studies expected to be undertaken in 2007/2008.

The infill drill program at Boomerang is now in progress using one drill and is anticipated to be complete in May 2007. Snowden will update the Boomerang resource estimate with results from the infill program and the completed resource estimate is expected in June 2007.

Domino Resource Estimation Begins

Messina has expanded the scope of Snowden's resource estimation to include that portion of Domino that has sufficient drilling to demonstrate continuity of mineralization with economically interesting grades. The completion of the preliminary Domino resource estimate is anticipated in June 2007. Exploration drilling at Domino will continue with the objective of discovering extensions to this base metal mineralization that can, in time, be added to the developing mineral resource.

Tulks East B Zone Resource Estimation Begins

The Tulks East "B Zone" is located 20 kilometers northeast of Boomerang/Domino also within Messina's Tulks South Property. The B Zone is one of several zones of base metal mineralization identified in the 1970's on Messina's properties for which an historical resource estimate was produced. The historical estimate of B Zone mineralization from surface to 200 meters vertical depth yielded 200,000 tonnes grading 8.7% zinc, 1.3% lead, 0.7% copper, 59 g/t silver, and 0.14 g/t gold (Barbour and Thurlow, 1982; as cited in Dearin, 2006 NI43-101 Report on the Tulks South Property; available on Sedar and from Messina's website). This is an historical estimate of mineralization only, is non-compliant with current NI43-101 standards, and should not be relied upon as estimates of absolute tonnage and grade. Messina completed 5 holes in 2004 at the B Zone which successfully intersected and confirmed similar base metal mineralization from surface to 70 meters vertical depth. Lakefield Research completed preliminary metallurgical tests in 2005 on B Zone mineralization; these tests were positive. Full results are available from Sedar or Messina's website.

All B Zone holes have been compiled into one database; geotechnical testing has been completed on Messina's 2004 drill core, and this data has been submitted to Snowden. A NI43-101 compliant resource estimate for the B Zone is anticipated for June 2007.

Other Historical Resources

Messina is working to upgrade other zones of base metal mineralization with historical resource estimates on its properties to current NI43-101 standards for inclusion in the Company's developing mineral inventory. These other historic resource estimates include the Skidder 'deposit', the Tulks East A Zone, the Tulks East C Zone, and the Long Lake Main Zone. The Skidder and Main Zone mineralized areas are planned to be drill tested in 2007.

About Messina

Messina is drilling zinc-lead-copper-silver-gold enriched massive sulphides adjacent to the Boomerang massive sulphide mineral resource, within the Company's Tulks South Property located in central Newfoundland, Canada. The Tulks South Property represents a portion of the 327 square kilometer area of Messina's central Newfoundland mineral land holdings. The region is historically known as prospective for zinc-rich deposits and home to the formerly producing world-class base metal deposits at Buchans and currently home to a producing zinc-copper mine at Duck Pond.

Kerry Sparkes, Vice President Exploration of Messina Minerals Inc. is the Qualified Person responsible for exploration on the Company's properties in central Newfoundland and the person responsible for the technical data contained within this news release.
