RML Rusoro Mining Ltd

Rusoro Mining Ltd. (TSX VENTURE:RML) is pleased to report that a 43-101 report
prepared by independent consultants Micon International Ltd. for the Isidora and
Twin Shear gold projects has been filed. Both projects were part of the assets
acquired in the acquisition of Hecla Mining Company's Venezuelan assets. The
total resources outlined in the report for Isidora confirmed the resources
originally estimated by Rusoro with the Twin Shear estimation out performing all
previous estimates by adding 482,000 Inferred gold ounces to the Company's total
resources.


Highlights of the report include;

- Proven and Probable Mineral Reserves at Isidora (March 2008) are 168,000 oz Au
(161,900 t @ 32.3 g/t Au). Mineral resources for Isidora are 331,000 oz Au
(470,000 t @ 21.9 g/t Au) of Measured and Indicated and 45,000 oz Au (99,000 t @
14.1 g/t Au) of Inferred.


- Mineral resource for the Twin Shear Zone is 482,000 oz Au (1.2 Mt averaging
12.5 g/t Au) of Inferred.


- The company now has a total of 6.87 M oz Au (84.5 Mt @ 2.52 g/t Au) Measured
and Indicated and 6.81 M oz Au (109.6 Mt @ 1.93 g/t Au) Inferred.


Rusoro President, George Salamis, states that, "The Company is very pleased that
the overall resource reported in the technical report is more favorable than
originally thought. This combined with both deposits being open from an
exploration perspective makes both projects very exciting moving forward."


The Mineral Reserves were estimated using a cut-off grade based on actual
operating costs from 2007 and were adjusted for production up to March 31, 2008.
Total direct operating costs used are $308.98/t of diluted ore with an assumed
gold price of $570/oz and a mill recovery of 94.4%.


The Isidora Mine Resources were estimated by mine staff and confirmed by Micon
as the independent QP. The estimates were completed using an 8 g/t Au cut-off, a
cap of 200 g/t Au with densities of 2.68 for vein material and 2.88 for waste
rock. The Twin Shear Resource was estimated by Scott Wilson RPA using a cut-off
of 8 g/t Au and a grade cap of 50 g/t Au with a density of 2.7 used for all
material.


Mineral resource estimates which are not mineral reserves do not have
demonstrated economic viability. The estimate of mineral resources may be
materially affected by environmental, permitting, legal, title, taxation,
socio-political, marketing, or other relevant issues. The quantity and grade of
reported inferred resources in these estimates are uncertain in nature and there
has been insufficient exploration to define these inferred resources as an
indicated or measured mineral resource and it is uncertain if further
exploration will result in upgrading them to an indicated or measured category.


Diamond drilling was conducted by independent contractors for Hecla Mining
principally using HQ-diameter drill holes. Mineralized sections were split using
a core saw and the second half of core remains for inspection and/or additional
tests. All sample analyses were conducted by independent contractors using
industry standard fire assays. A stringent QA/QC program was utilized including
the insertion of standards and check assays for all ore grade samples.


All aspects of the reserve and resource estimates as well as the QA/QC are
described in detail in the analysis in the technical report by Micon
International with contributions from Scott Wilson RPA for information relevant
to the Twin Shear deposit and resource estimate.


Qualified Person: Mr. Gregory Smith, P.Geo, the Vice-President Exploration of
the Company, is the Qualified Person as defined by National Instrument 43-101,
and is responsible for the accuracy of this news release.


About Rusoro Mining: Rusoro Mining is a junior gold producer with a large land
position in the prolific Bolivar State region of Venezuela. The Company operates
the Choco 10 and Isidora Mines, processing the ore through the Choco Mill
facility near the town of El Callao. The Company has significant 43-101
compliant gold resources and will produce approximately 150,000 oz/Au in 2008.
Rusoro is scheduled to drill up to 300,000 meters in 2008 to expand and upgrade
its gold ounces for projected production expansion at both the Choco 10 Mill in
El Callao and the Emilia Mill in El Dorado where the SREP Mine should be
operating by year end.
