The Company completed the acquisition of Guinor on December 14, 2005 and accordingly, the results of Guinor from that date to the
year-end are included in the Crew financial statements for the year ended June 30, 2006.

Nalunaq includes 42,836 tonnes shipped prior to year end and not recognised as sold in the period due to the ice delay. Therefore the gold produced and sold in the quarter are reported as nil. These amounts will be reported in the next quarter. |

Nalunaq Gold Mine: Results from Mining
The Nalunaq resource is a narrow vein deposit consisting of several
high-grade “bands” typically carrying grades of around 30 g/t or
higher. Between the high-grade bands, grades can vary between
10 g/t and 20 g/t. In practice this means that the grades achieved
on an ongoing basis can vary considerably.
During the fourth quarter of fiscal 2006, $0.6 million (2005: $0.8
million) was spent on further development of the mine and the total
expenditure for the year was $2.4 million (2005: $3.2 million).
The focus of this work was ramp development required to connect
the South and Upper Block Areas to the existing Target Block and
drilling associated with the expansion of the overall resource base.
Ore production for the fourth quarter was 33,223 tonnes, an
average of approximately 365 tonnes a day, and for the year was
123,763 tonnes representing an average of 339 tonnes per day.
This in line with expectations given the higher level of development
undertaken on the mine’s infrastructure in the period and the
increased focus on achieving higher quantities of higher grade ore.
The daily production target when the new equipment is utilized is
expected to be in excess of 500 tpd.
Owing to prevailing ice conditions, at the end of the fourth quarter
of fiscal 2006, along the southwest coast of Greenland, access to
the fjord entrance leading to the mine harbour was not navigable.
Consequently the arrival of the ore ship MV Baffin was delayed by
11 days. 42,386 tonnes of ore were shipped for processing on this
shipment. Loading was completed on 28th June 2006 and the ship
had clear passage to Aviles in Spain where the ore is offloaded.
The ore was offloaded in Aviles in early July at which point title to
the ore passed to Rio Narcea. As a result of this delay, the June
shipment is required to be recognized as a sale in the next financial
year even though the ore was produced in the year.
For the 2006 year’s production at Nalunaq, 145,419 tonnes
(2005: 111,741 tonnes) of ore have been shipped for processing
and gross gold production totals 74,731 ounces (2005: 55,975
ounces) which represents a head grade of 19.0 grammes per tonne
(2005: 15.9 grammes per tonne). This represents an improvement
in head grade of 19.5%. After tailings and efficiency fees, 57,960
ounces of gold were sold in the year with a gross value of $29.9
million. This compares to 52,866 ounces of gold sold in the prior
year with a gross value of $23.0 million. After accounting for
annual processing costs of $4.1 million (2005: $4.5 million), net
sales of $25.8 million (2005: $18.5 million) have been realised for
the year under review.
Management is pleased with the increased tonnage of ore
produced in the year and the higher grade of gold achieved.
Management believes these improvements were achieved through
improved mining techniques which reduced mining dilution.
Management also believes that the addition of newer more reliable
mining vehicles and equipment to ensure a sustainable balance
between mine development and stage production will further
improve productivity within the mine and production rates in the
forthcoming year.
Lefa Gold Mine: Results from Mining
During the fiscal year, management decided to continue the Lefa
heap leach operation, in spite of higher costs, as it was necessary
to retain key plant personnel until they can be transferred to the new
CIP plant. The quantity of ore processed could have been
increased during the year however it was decided to process only
enough ore to generate cash to cover operating costs. The balance
of the ore was stockpiled for processing through the higher
recovery CIP process.
Ore mined from the Lero pit in the period since the acquisition of
Guinor totalled 317,257 tonnes at a grade of 2.88 g/t, containing
29,426 ounces. This was supplemented with 115,262 tonnes at a
grade of 0.94 g/t, containing 3,498 ounces moved from the lowgrade
stockpiles to provide additional material for the heap leach
operation.
Ore processed in the period since acquisition was 459,152 tonnes
at a heap grade of 2.17 g/t, containing 31,985 ounces of gold.
Gold recovered in the period since acquisition from the heap leach
operation was 20,428 ounces. This was below expectation and the
shortfall arose primarily from plant shutdowns following a gearbox
failure and damage to the apron feeder as well as fuel shortages.
Gold recoveries from the low-grade ore from the stockpiles were
also lower than expected and both mining and plant throughput
were adversely affected by low equipment availabilities.
Gold sold in the period since acquisition was 20,646 ounces. Total
revenue from gold sales amounted to US$11.9m and the average
price realized was US$576 per oz.
Average cash cost per ounce from the heap leach operation for the
period since acquisition was $449 per oz. Average costs were
high due to the low production and a high proportion of production
costs being fixed however this was expected. Gold production
increased significantly towards the end of the period, when higher grade material from the Lero pit was processed. This is expected to
continue to December 2006 when the heap leach operation is
decommissioned and replaced by the new CIP Plant. Management
believes this will result in improved results from the operation being
recorded in Q1 of calendar year 2007.
Gold production from the heap leach operation in calendar year
2006 is expected to be approximately 52,000 ounces at an
average cash cost of approximately US$400/oz. Management
will continue to review production plans to ensure that existing
operations are self-sustaining whilst preserving as much of the high
grade mine reserves as possible for processing through the more
profitable CIP Plant expansion project.
Barberton Mines Limited
Barberton’s results for the year under review were in line with the
previous year; decreases in gold sales were compensated by
increased gold prices. In order to focus on its development and
managed projects, the Company chose to dispose of its interest in
Barberton.
Following year end, Crew agreed to divest of its interest to Metorex
Limited (“Metorex”), one of its partners in Barberton and a
company listed on the JSE, in return for Metorex shares valued at
ZAR 84 million (US$11.8 million), representing a significant
increase over both the cost and carrying value of the investment.
The profit on sale will be recognised in the financial statements in
the first quarter of fiscal 2007.
