    The Lundberg and Engine House resource estimates are based on a
combination of 45 drill holes completed from surface by Royal Roads in 2008
and 136 historic drill holes completed from surface and underground prior to
1975 by former mine operators, American Smelting and Refining Company
("ASARCO"). The Lundberg deposit comprises disseminated and stringer base
metal sulphides beneath the mined out Lucky Strike massive sulphide orebody
from which Asarco produced 5.6 million tonnes(1) averaging 17.39% zinc, 8.20%
lead, 1.51% copper, 113.6 g/t silver and 1.68 g/t gold prior to the Buchans
mine closing in 1984. A large portion of the Lundberg deposit extends to
surface beneath overburden that is typically less than 10 metres thick, or at
similar depths below the floor of the Lucky Strike glory hole (former mine
workings now exposed at surface). The Engine House deposit is predominantly
comprised of similar disseminated and stringer sulphide mineralization where
ASARCO mined 256,646 tonnes(2) averaging 4.96% zinc, 1.70% lead, 1.50% copper,
25.0 g/t silver and 0.48 g/t gold.
    The Lundberg and Engine House deposits are being evaluated for their bulk
tonnage-open pit mining potential. The Company is also assessing the Lundberg
deposit for discrete higher grade zones within the larger mineralized
envelope.
    The new Lundberg resource estimates represent a significant expansion of
the deposit which in 1974, ASARCO estimated to contain approximately
11.9 million tonnes(3) averaging 2.88% combined base metals comprised of 1.83%
zinc, 0.67% lead, 0.38% copper, 5.5 g/t silver and trace gold based on a
cut-off of 1% combined base metals (Cu%+Pb%+Zn%). The ASARCO estimate is
historic in nature, having been prepared before implementation of NI 43-101
and therefore cannot be relied upon (details for the historic estimate are
more fully disclosed in Buchans River's news release dated September 10,
2007). For comparative purposes, Mercator were instructed to complete an
additional resource estimate using a threshold of 1% combined zinc, lead, and
copper, similar to parameters used by ASARCO. On this basis, Mercator
estimates the deposit to include an Inferred Resource of 20.5 million tonnes
grading 2.78% combined base metals comprised of 1.68% Zn, 0.72% Pb, & 0.38%
Cu. This estimate, which includes new drilling beyond the limits of previous
ASARCO drilling, represents a tonnage increase of more than 70%. Importantly,
the mineralization remains open in several directions, including areas where
the deposit is predicted to extend to surface.
    A plan map showing the current interpreted limits of the Lundberg and
Engine House resource estimates as calculated by Mercator is available on the
Royal Roads' website at http://www.royalroadscorp.ca.

    Management's Opinion
    --------------------

    Will Felderhof, President and CEO of Royal Roads stated, "We are very
pleased with these resource estimates especially given that, at a 2% Zn
cut-off, approximately 70% of the Lundberg resource occurs within 100 metres
or less from surface in an area offering excellent infrastructure. The
potential for further resource expansion at shallow depths is excellent."

        from an article by Thurlow., J.G., and Swanson, E.A., published in
        1981: Geology and ore deposits of the Buchans area, central
        Newfoundland. In: Swanson, E.A., Strong, D.F., and Thurlow, J.G.,
        (editors), "The Buchans Orebodies: Fifty Years of Geology and
        Mining". Geological Association of Canada Special Paper 22. Page 122,
        Table II.

    (2) Past production figures for the Engine House orebody were obtained
        from archived ASARCO records.

    (3) Trace gold is less than 0.01 ounces per ton gold (i.e. less than
        0.35 g/t gold), the lower detection limit of historical gold assays
        used in ASARCO's resource estimate.
    

    Estimation Methodology
    ----------------------

    The resource estimate reflects a three-dimensional deposit block model
developed by Mercator using Surpac(C) Version 6.0.3 deposit modeling software.
Analytical results for 181 diamond drill holes were used to calculate the
resource estimate in this model, of which 45 drill holes are from recent
Company drilling (6,860 meters), and 136 drill holes are from validated
historic data. The model utilized 1 metre down-hole assay composites
individually calculated for Zn(%), Pb(%), Cu(%), Ag(g/t), Au(g/t), and BaSO4
assay values. Model blocks measured 5 m x 5 m x 5 m with sub-blocking at 2.5 m
x 2.5 m x 2.5 m within the Lundberg solid, and 2.5m x 2.5m x 2.5m with
sub-blocking at 1.25m x 1.25m x 1.25m for the Engine House solid.
    The model was constrained by individual wireframed solids representing
resource estimates for the Lundberg and Engine House zones respectively. The
wireframes were based on geological sections, that reflect a minimum included
grade of approximately 1% combined base metal (Zn% + Pb% + Cu%) with dilution
considerations limited to a maximum of 40% of the overall drill hole
intersection. No high grade capping factors were applied due to the spatial
correlation of high grade samples. The Lundberg resource solid occurs between
the bedrock-overburden interface and plunges to a maximum depth of
approximately 350 metres below surface, and the Engine House solid elevation
ranges from between 25 metres to a depth of approximately 145 metres below
surface. Historical underground development was reviewed and, where
information was available, was modeled into 3-dimension solids. All resource
block model volumes that lay within the underground workings solids were
removed from the resource estimate after the grade interpolation process was
completed, and were not reported as part of the final volume and grade
calculations of the resource estimate.
    Metal grades were assigned to the block model using inverse distance
squared (ID2) interpolation methodology with blocks being peripherally
constrained by wireframe solids. The Lundberg solid incorporated two
interpolation domains which were defined as north and south of gridline 7930N.
Two unique interpolation ellipses were determined for these two domains. Major
and minor axis parameters were selected based on continuity and distribution
of metal grade and reflect geological characteristics of the mineralized
zones. The Engine House estimate was based within a single interpolation
domain, and used an isotropic model with a 75 metre range.
    Results of 2,266 separate laboratory determinations of specific gravity
("SG") were used in the block model. The mean SG value from within the
resource solids of 2.88 g/cm(3) was assigned to blocks occurring within the
Lundberg and Engine House models.
