Blackhawk Resource Corp. Reports Significant Reserve Additions From First Quarter Drilling Program

Blackhawk Resource Corp. ("Blackhawk" or the "Corporation") (TSX VENTURE:BLR) is
pleased to announce the following reserve additions relating to the successful
completion of the 100% owned BLR Bodo #1 and BLR Bodo #2 wells which were
drilled in the first quarter of 2010. The new well reserve estimates were
prepared by AJM Petroleum Consultants with an effective date of April 30, 2010
using the AJM March 31, 2010 price forecast. The two well program, including
drilling, equipping and tying-in the wells, cost approximately $2.1 million and
increased Blackhawk's proved plus probable before tax net present value,
discounted at 10%, by more than $11.2 million.

The estimates of reserves and future net revenue for individual properties may
not reflect the same confidence level as estimates of reserves and future net
revenue for all properties, due to the effects of aggregation.


All barrels of oil equivalent ("boe") conversions in this release are derived by
converting natural gas to oil in the ratio of six thousand cubic feet ("Mcf") of
gas to one barrel ("bbl") of oil. A boe conversion ratio of six mcf to one
barrel is based on an energy equivalency conversion method primarily applicable
at the burner tip and does not represent a value equivalency at the wellhead.
