    Production Table Notes:

    1. Production statistics are on a 100% basis.
    2. Cash cost per payable ounce of silver or payable pound of copper is a
       non GAAP measure. The Company believes that, in addition to cost of
       sales, cash costs per ounce or per pound is a useful and complementary
       benchmark for performance and is well understood and widely reported
       in the mining industry. However, cash costs per ounce does not have a
       standardized meaning prescribed by Canadian GAAP. Investors are
       cautioned that cash costs per ounce or per pound should not be
       construed as an alternative to cost of sales determined in accordance
       with Canadian GAAP as an indicator of performance. The Company's
       method of calculating cash costs per ounce or per pound may differ
       from the methods used by other entities and, accordingly, the
       Company's cash costs per ounce or per pound may not be comparable to
       similarly titled measures used by other entities.
    3. Average commodity prices used to off-set (by-product credit basis) or
       allocate (co-product basis) cash costs are the monthly weighted
       average realized prices based on invoiced shipments.
    

    Exploration Update
    ------------------

    Revett's drill program recently produced some very promising results at
the Troy Mine with drilling targeting expansion of the South Ore Body Lower
Quartzite area. While the Lower Quartzite is typically a lower grade area, the
results of this drilling are particularly promising due to the significantly
higher grades in drill hole 09-LWA77SW-14 with silver grades averaging two
times higher than normal over a nearly 25 foot thick interval. This area
remains open to the south and follow up drilling is anticipated to further
define the potential for expansion of reserves in this area.
    From December 1, 2008 through April 2, 2009, the Troy Mine drilled
fourteen (14) NQ2 diamond drill holes in the South Ore Body Lower Quartzite
West Stope. The drilling, designed to extend the orebody to the south beyond
the previous drill data and to increase the confidence in ore quality in this
area, included low angle fans of holes to extend the ore zone and short
vertical holes to define bench ore.
    Below is a table summarizing the results of this drilling program.
Reserve/resource calculations are in progress with the results expected to
increase both tonnage and grade for mill throughput from this stope in 2009.

    A total of 402 samples were taken from the fourteen core hole intercepts
in the Lower Quartzite of the Upper Revett. Detailed geologic logging
identified the mineralized intervals to be sampled. All the samples were
prepared from the entire NC cores (~2"). In general, four foot intervals were
sampled. All samples were analyzed for copper, silver and lead using atomic
absorption spectrometry. Sample intervals determined to be within the ore zone
were analyzed for non-sulfide copper.
    The Troy Mine laboratory prepared the samples and performed the assays.
The quality assurance / quality control at the Troy Mine laboratory consisted
of 45 analyses of standard samples. The average differences between the mine
laboratory results and the known samples were 0.005 ounces per ton for silver
(2.2%) and 0.003 percent for copper (2.5%) for the low grade standard and
0.001 ounces per ton for silver (0.1%) and 0.007 percent for copper (1.4%) for
the ore grade standard. For information regarding the geology and mineralogy
of the Troy Mine Deposit, refer to the Company's Form 10-K, filed March 31,
2009.
    Mr. Larry Erickson, an employee of the Troy Mine and Revett's Qualified
Person, has verified the data relating to the results of drilling disclosed in
this press release and has reviewed the contents of this press release.
    Mr. John Shanahan, President and CEO, noted "Our exploration and
operating teams are very excited about our first quarter achievements and
exploration prospects. This coupled with the recent rebound in metals prices,
has strengthened our confidence in operations at the Troy Mine."
