3.1. OPERATIONS - MACRAES GOLD PROJECT
3.1.1 HIGHLIGHTS
* Record fourth quarter gold sales of 47,074 ounces at a cash cost of
A$297 per ounce resulting in annual gold sales of 168,967 ounces, at
a cash cost of A$296 per ounce.
* Commitment to a Continuous Improvement alliance with Caterpillar
(Australia) and Goughs (NZ), following their appointment as the
preferred supplier of mining equipment and maintenance services at
Macraes.
3.1.2 REVIEW OF OPERATIONS
FOURTH QUARTER
Gold production during the fourth quarter was 45,899 ounces, at a
cash cost of A$297 per ounce sold.
Processing of sulphide ore recommenced at the start of October
following two months of oxide processing in the third quarter.
The record quarter was underpinned by favourable ore grade and
recoveries. A better than expected high-grade zone was mined in
Golden Point resulting in 19,312 ounces produced in December.
Mining continued at Deepdell, Golden Point and Innes Mills pits
whilst waste stripping commenced at Frasers South towards year-end.
The appointment of Caterpillar as the preferred supplier of mining
equipment and maintenance services at Macraes follows a comprehensive
owner-mining study and contract mining tender.
The transition from Macmahon Contractors to owner-mining will occur
in June 2002.
2001
Annual gold production of 169,571 ounces at a cash cost of A$296 per
oz is consistent with the previous year's result and the long-term
expectation of 170,000 - 180,000 ounces at 2 cash cost of A$280-320
per ounce.
Ore was sourced from Deepdell, Golden Point, Southern and Innes Mills
pits all of which reconciled favourably to resource model
predictions. The overall reconciliation was 11% favourable to
expectation.
Total ore processed was on target with sulphide processing generally
performing to budget. Oxide processing for two months during the
third quarter while not on budget, enabled deferment of waste
stripping. The option of processing oxide by heap leaching is being
considered.
A total of two lost time injuries were incurred during 2001 resulting
in LTI injury frequency rate of 3. This outcome is consistent with
2000 and compares favourably with the industry average.

3.2. DEVELOPMENT
3.2.1 MACRAES GOLD PROJECT
PROCESSING PLANT
The 15% upgrade of Macraes milling capacity from 3.9 Mtpa to 4.5 Mtpa
(MREP-2) is on schedule for completion by mid 2002. The annualised
mill throughput for December was 4.25 Mt whilst the annualised
throughput of sulphide ore in 2001 was 4.16 Mt. The upgrade entails a
series of de-bottlenecking and efficiency enhancing activities.
OWNER-MINING
The appointment of Caterpillar (Australia) and Goughs (NZ) as the
supplier of equipment and maintenance services has been expanded to
include a formal Continuous Improvement agreement. The risk and
reward agreement binds both parties to ongoing investment in
continuous improvement initiatives targeting a minimum 2% improvement
in mining cost per annum.
3.2.2 REEFTON GOLD PROJECT
Board approval to develop the Reefton Gold Project was obtained in
December following successful conclusion of the outstanding matters
relating to the existing 15-year access agreement with the Department
of Conservation
The development of the project will entail establishing the necessary
infrastructure including an access road and bridge prior to the
commencement of major earthworks and plant construction in September
2002.
The viability of the Project was secured following the forward sale
of 200,000 ounces at historically high gold prices averaging over
$665/oz on a spot deferred basis. GRD is now in a position sell up to
80% of the future gold production. taking full advantage of the near
record high NZD gold price.
3.3. EXPLORATION
3.3.1 MACRAES GOLD PROJECT
FRASERS NORTH OREBODY EXTENSION
Success was encountered from further drilling of this established ore
body, providing an indication of potentially significant Resource
extension.
The first hole completed to target depth RCD4218 intersected weak
Hanging Wall mineralisation of 6m at l.llg/t at 4l2 metres.
The next two drill holes RCD 4220 and RCD 4221 respectively 200m and
400m south intersected the Hanging Wall at a slightly shallower depth
than RCD4218 and intersected strong gold mineralisation with visible
gold observed in one of the drill holes.
The significant intersections are listed below.

* Interval 424 - 425m assayed at 46.7 g/t. The intercept was however
calculated with a standard 15 g/t cut.
These two drill holes have extended the Fraser's North Orebody a
further 400 metres down dip to the east and the ore body still
remains open to the South. Drilling during the first quarter of 2002
will continue on a 200 metre spaced pattern to determine the full
width of the extension to the ore body.
MACRAES NORTH
An exploration permit for Macraes North covering the northern 7 km of
the Hyde Macraes Shear Zone has been obtained, successfully
completing the 10-year strategy of having the entire Hyde Macraes
Shear Zone under GRID Macraes control.
The Macraes North exploration permit contains the known northern
strike extensions of the currently producing Deepdell pit and a
number of old workings (Coronation, Nunns, NZGT and Mareburn) and
previous explorers of the respect workings have recorded a number ore
grade drill intersections as listed below.

3.4. MINERAL RESOURCE AND ORE RESERVE
3.4.1 MINERAL RESOURCE
The Mineral Resource Estimate as at 31 December 2001 is 5.19 million
ounces from 109.12 million tonnes of ore at an average grade of 1.33
g/t.
MINERAL RESOURCE ESTIMATE AS AT 31 DECEMBER 2001
PROJECT CUT OFF GRADE TONNAGE GRADE OUNCES
(G/T) (MT) (G/T) (Moz)

Reefton 0.9 14.85 2.81 1.34
Total 109.112 1.33 5.19
The Macraes Mineral Resource Estimate of 3.85 million has decreased
by 320,000 ounces, through annual depletion and sterilisation of
uneconomic gold following the conversion of Southern pit to a
tailings impoundment.
3.4.2 ORE RESERVE
The Ore Reserve Estimate as at 31 December 2001 is 2.76 million
ounces derived from 54.5 Mt tonnes of ore at an average grade of 1.58
g/t.
ORE RESERVE ESTIMATE AS AT 31 DECEMBER 2001
PROJECT CUT OFF GRADE TONNAGE GRADE OUNCES

Macraes 0.5 47.6 1.43 2.18
Reefton 0.9 7.0 2.59 0.58
Total 54.5 1.58 2.76
The Macraes Ore Reserve estimate of 2.18 million ounces remains
largely unchanged since 1997 despite the depletion of 0.68 million
ounces through production over the past five years.
This has been achieved through the introduction of pressure oxidation
and the subsequent 20% improvement in gold recovery, mine planning
enhancements and infill drilling.
The overall Resource to Reserve conversion amounts to only 53%.
3.5. HEDGING
As at 31 December 2001, the mark to market value of the Company's
gold hedge and options book was $96.18 million deficit. This mark to
market was based on a spot price of $539.17 (US$276 00 and A$/US$
exchange rate of 0.5119) at the end of the quarter.
The mark to market value of the Company's gold hedge and options book
has reduced to $85 million deficit as at 29 January 2002.
