TORONTO, Dec. 31 /CNW/ - Guyana Goldfields Inc. (TSX: GUY) ("Guyana" or the Company") is pleased to announce the completion of an initial Mineral Resource
Estimate for the Company's wholly owned Sulphur Rose property at its
Aranka group of properties in Guyana, approximately 35 kms away (by
road) from the Aurora Gold project.
Resource estimate includes 460,400 ounces of inferred resources.
Infill drilling with the objective of upgrading inferred resources to
measured and indicated will commence in the New Year.
Potential for further resource additions in nearby areas considered
Exploration potential remains open at depth and along strike.
The reported resource contains 6,853,000 tonnes with an average grade of
2.09 grams per tonne Au ("g/t") for a total of 460,400 contained ounces
of gold in the inferred category, as set out in the table below. The
base case resource was estimated assuming a long term gold price of
US$1,000 per ounce. Open pittable mineral resources were determined
from a conceptual pit, designed using Whittle software, metallurgical
test results from Sulphur Rose mineralization and operating costs
estimated for the nearby Aurora project. Potentially mineable
underground mineral resources were determined from the remaining
mineral resource below the pit bottom using mining costs determined for
the Aurora project and Sulphur Rose metallurgical recovery results,
after leaving a 30 m thick crown pillar.
Sulphur Rose Inferred Mineral Resource
Note: Table may not add precisely due to rounding errors.
1 - Determined using the following assumptions: $1.45/t mining, $10.02/t
processing, $10/t G&A and 91.9% recovery.
2 - Determined using the following assumptions: $75.70/t mining,
processing and operating costs and 91.9% recovery.
The mineral resources above were determined using the "CIM Standards on
Mineral Resources and Reserves - Definitions and Guidelines" as adopted
by CIM Council on December 11, 2005. The estimate's effective date is
December 29, 2010. Mineral resources are not mineral reserves and do
not have demonstrated economic viability. At this time the mineral
resources are not understood to be materially affected by any known
environmental, permitting, legal, title, taxation, sociopolitical,
marketing, or other relevant issues.
Patrick Sheridan, CEO of Guyana Goldfields, commented: "The initial
resource estimate at Sulphur Rose highlights the robust nature of this
project with attractive grades and good widths. This initial resource
estimate represents a strong starting point as we continue to advance
the deposit forward with our expectation that significant potential
exists to add ounces both at Sulphur Rose and at other nearby
prospective properties within Aranka."
The reported open pittable mineral resource extends from surface to a
vertical depth of approximately 215 metres. The underground portion of
the resource was determined from a block model which extends to 630
metres below surface, with the deposit remaining open to depth.
The initial Resource Estimate for Sulphur Rose will be evaluated for
possible inclusion in the Aurora Feasibility Study. The Aurora revised
Resource Estimate is due to be completed in Q3 2011 with the final NI
43-101 Technical Report due in Q4 2011.
The Company expects to be able to complete an updated resource estimate
at Sulphur Rose by the end of the second quarter in 2011.
The Company has significantly allocated more drills and funds to the
exploration program at Sulphur Rose and at its other Aranka properties,
currently known as Wynamu, North Ridge, Pakira Hills and Kopang. A
total budget of up to ~$10million will be spent for 2011 with up to 6
drill rigs to support the extensive exploration efforts. Guyana
Goldfields will continuously report on the drilling success of these
properties as the programs progress.
