VANCOUVER, BRITISH COLUMBIA is pleased to report that the
Technical Report supporting the Monument Bay mineral resources as
reported on January 8, 2008 is now filed on the Company's profile
at www.sedar.com.
The new estimation increased the inferred mineral resource by
35% to 944,000 ounces gold from 701,000 ounces gold. The resource
estimate was made by Thomas C. Stubens, M.A.Sc. P.Eng., Senior
Geologist of Wardrop Engineering Inc.
The report titled Monument Bay Gold Deposit; Focus on Gold
Inventory Update incorporates all previous work to date including
over $28 million of exploration expenditures with over 100,000
metres of diamond drilling. The Technical Report was prepared by
J.T. Shearer, M.Sc., P.Geo along with Jose Garcia; the Company's'
Senior Project Geologist.
Monument Bay is Rolling Rock's 100% owned flagship project that
was acquired in March 2006 from what was then Bema Gold Corporation
and Wolfden Resources. Monument Bay is located in Northeastern
Manitoba, 350 kilometers southeast of Thompson. Red Sucker Lake,
with full hydro electric power and airport services as well as
winter road access, lies 60 kilometers to the southwest. The
project consists of 35 contiguous claims and a mining exploration
license covering 25,706 hectares in area.
The significant increase in this inferred resource is mainly
contributed by additional mineralized volume from the newly
discovered Burn Zone, the expanded G Zone and the main body east
extension.

The mineral resource update, particularly the Block Model, has
enhanced the understanding of the continuity, geometry and gold
grade distribution for each of the 13 veins modeled in this study
of the Monument Bay project.
As recommended in the report, Rolling Rock has now contracted
Beacon Hill Consultants Ltd. to carry out a Preliminary Assessment
Mining Plan (scoping study). This will determine the economic
viability of pursuing underground development work for more
diagnostic mapping and sampling of the deposit as well as to serve
as a platform for more cost-effective definition drilling to
upgrade the resource category and eventually convert the mineral
resource to mineral reserve.
Parameters used for the updated resource estimates are as
follows:
- The mineral resource in the table was estimated using CIM
standard on mineral resources and reserves.
- The total database is comprised of 414 drill holes aggregating
113,703.6 metres (373,061.7 feet) of core drilling.
- Within the area of the resource inventory update, there were
341 holes totaling 96,578.7 metres (316,874.8 feet), of which
38,985.48 metres (127,911.4 feet) of the core was sampled and
assayed in accordance with industry best practice procedures. These
yielded a total of 38,043 gold assays that had passed
industry-standard QA-QC protocol.
- The inferred resource consists of thirteen geologically and
geographically distinct mineralized solids (veins) with distinct
structural-stratigraphic, alteration-mineralization and sulphide
assemblage characteristics.
- Grade interpolation is based on 1meter length composites
within each geological unit or vein. The cutting thresholds used in
Wardrop's 2006 Technical Report (previously filed on the Company's
profile on www.sedar.com) were employed in this study.
- Block models were established in Datamine for each of the 13
veins, truncated at the bedrock-overburden surface, using an
inverse distance cube estimation procedure, with directional
parameters (distance and direction) based on the attitude and
continuity of the mineralization in each vein.
- Block model dimension is 10m by 1m by 10 m (Easting x Northing
x Elevation), with sub cell size of 5m (Easting - X) by 0.5m
(Northing - Y) and infinite splitting on the Z direction, to best
model the narrow steeply dipping veins.
- Only blocks lying within 50 metres of a drill hole composite
have been included in the estimate.
